Phalasa - An Animator's Art Album
I'm a Polish/Canadian artist who is currently completing a bachelors in animation here in Canada, I just wanted to share some of my work, I only recently took up photoshop seriously, I am more of a traditional artist.
My goal is to get better in conceptual work so I can take characters from concept and bring them to life with animation. I believe photoshop is really important now in the conceptual art industry.
Thanks for your time guys, tell me what you think.

Hi Phalasa, welcome to CA . Really nice stuff here. Looking for some comments :p. Euhm for the rider with the beast piece, I think you could soften your shadow more to the end. Because his tail is higher and the cast shadow wouldn't be that strong I think.
Liking the boxer and those 2 environments very much though. Are you going to color up those environments?
Have fun drawing .

More About Leptin Feedback Control System
Demonstrates how changes in the amount of fat tissue lead to changes in leptin levels and thus changes in appetite.
Leptin Feedback Control System Background
Leptin is a hormone that is produced by fat tissue found throughout the body. The amount of leptin produced is proportional to the amount of fat tissue. If someone reduces their caloric intake, their fat tissue will decrease, and the leptin signal will also decrease. This decreased signal reaches an area of the brain called the hypothalamus. The hypothalamus responds to the reduced signal by increasing the desire to eat. Once the amount of fat tissue is back to the usual level, the amount of feeding also returns to the usual level. Likewise, if someone increases their caloric intake, their fat tissue increases, as does the amount of leptin signal reaching the hypothalamus. This increased signal to the hypothalamus results in a decreased desire to eat. This eventually returns the amount of fat tissue to the usual level, which in turn returns feeding to the usual level.
From Lecture One of the 2004 Holiday Lectures Series "The Science of Fat."
Leptin Feedback Control System Teaching Tips
The animations in this section have a wide variety of classroom applications. Use the tips below to get started but look for more specific teaching tips in the near future. Please tell us how you are using the animations in your classroom by sending e-mail to email@example.com.
- Use the animations to make abstract scientific ideas visible and concrete.
- Explain important scientific principles through the animations. For example, the biological clocks animations can be used to demonstrate the fundamentals of transcription and translation.
- Make sure that students learn the material by repeating sections of the animations as often as you think necessary to reinforce underlying scientific principles. You can start, restart, and play back sections of the animations.
- Urge students to use the animations in accordance with their own learning styles. Students who are more visually oriented can watch the animations first and read the text later, while others might prefer to read the explanations first and then view the graphics.
- Incorporate the animations into Web-based learning modules that you create to supplement your classroom curricula.
- Encourage students to incorporate the animations into their own Web-based projects.

Publisher's Weekly
This simple message of belonging to the greatest King of all was created by Christian communicator, singer, and songwriter Sheila Walsh. Pink-loving princesses will love the whimsical illustrations by Meredith Johnson. Although royals of all ages may enjoy Gigi and her quest, its simple story line is probably geared to the youngest princesses who lay in wait for a bedtime story and a sweet reminder of Gods gracious love. -- Susan Hammond, Christian Book Previews.com

Le Méridien Mahabaleshwar Resort & Spa

Meaning "God of Great Power" in Sanskrit, small and picturesque Mahabaleshwar is a hill station situated in the Indian state of Maharashtra. Surrounded by rare evergreen forests in the Western Ghats is an atmosphere of unhurried relaxation at Le Méridien Mahabaleshwar Resort & Spa. We are located near the city centre on Satara Road.
Dating back to 1215, Mahabaleshwar has a rich cultural heritage and is an important pilgrimage site for Hindus. Hire an autorickshaw and visit one the nearby temples, including the iconic Mahabaleshwar Temple. Inspirational historical landmark sites can be found at Mount Malcolm, the Mahabaleshwar Club, and Moraji Castle. Glimpse at the pride of the Maratha Empire at Pratapgad Fort. Built in 1656, it is just 24 kilometres outside of town. Or capture the marvelous views at Wilson Point, Arthur's Seat, Baghdad Point, or Bombay Point.

Visitors can take a boat ride, fish, go horseback riding, and enjoy local cuisine and games in the entertainment area.
Gourmands will delight in the local gastronomy, including chikki, a traditional Indian sweet made with jaggery and nuts. The region is also highly regarded for its fruit products, strawberries, mulberries, honey, and jams. During strawberry or mulberry season, you can visit one of the local farms and pick them in the fields. For those interested in the art of making honey, stop by the educational beekeeping centre.

Originally written on NESN.com | Last updated 2/15/13
The Bruins have had some tremendous success in the late stages of games this season, and that could be playing out once again in Buffalo on Friday night. After trailing for much of the first period, the Bruins sprang into action, with Dougie Hamilton scoring his first career NHL goal. That knotted things up at 1-1, but something tells us the drama isn't done just yet in this one. NESN Nation's Dan Duquette is hoping the B's stay true to form and pull this one out. See why in the above video. Join NESN Nation: In-game home page | Twitter | Facebook Thumbnail photo via Facebook/Boston Bruins

Hovering Over Me.I just recently became very attracted to black men.. I guess since I moved to cali, I see the difference because back home where I am from all men dressed the same and act the same, black or white. I never cared about if the guy was black or white, but now that I see how the white peole act around here I am obly attracted to the black men. I can honestly say that black men know how to treat a woman better than white men. I am saying this about the men in the area I am in right now, not everywhere so dont get offened.
When I am with a black man, they treat me as if I am the only woman in the room, as if they can only see me and they cant take their eyes off me.. I feel so much lust when they touch my body. I can say that so far I have better sex with black men.. Its not about the size either. They know how to carress a womans body, they know how to make love instead of just ******* someone. I love it. I have been with black men before I moved out here but they never treated me like they do here, and I am enjoying it.
I love a muscular black man hovering above me, it just makes me enjoy sex just a little be more. :)
My wife told me she would never consider ******* a black man. Then she met two of them where she works, she could see the outline of their hugs ***** through their pants. One day they went out to lunch and while driving down the road, he reached over and started to rub her *****, she in turn reached over and started to rub his **** through his pants. When she felt the length of what he was offering, she had to try it. He is not only her lover now, but also the man who has bread her. It is amazing watching them together
you are hott n sexy.............im a white boi whos noticed my girlfreinds get weak around black men......they flirt and ignore me like im not there
I am writing a book about interracial realtionships and I would love to talk to you further about this. I would love to use your story in my book and the thing I need is what attracts you to black men? I am a white woman and I too am in love with a black man, Please feel free to write me back and tell me what it is that draws you to your man and I do promise to not use websites or names unless I have your appoval to use only a first name only, if you would rather submit without a name I can do it that way too. I appreciate your time. Thank you.
This was a great post.. :) i am an african american male, & it was nice to "hear" the "feelings" in your story. I bet it hit koolranch deep inside his heart like a spear.. the pain he felt was the reason he tried to make you feel bad with the dumb comments. Love has no color, (physically) or emotionally.. if you feel treated well, or (better), that is all that's important.. :)
your not alone as a wife i enjoy being with black men more and now have a black boyfriend that really keeps me satisfied

The symbol is a collection of a couple ancient symbols. One symbolizes part of the spirit while the other one is more closely related to death. The artist has dealt with a lot of inner turmoil, and the simplicity of the logo design contrasts the complexity of the music beautifully.

I have an 07 Tundra 5.7 this exhaust was easy to install with no modifications.I noticed an improvement in power and sound is great.
Reviewed By Stephen W (FREDERICKSBURG, VA) Reviewed for a 2006 Ford Explorer —6/26/2015 7:02 AM
The installation was fairly simple but you should make sure to "scrub" clean your exhaust pipe and use a metal polish to finish the job before installing the Gibson slash exhaust tip. The exhaust tip I ordered was 12 inches long but it could have been up to 14 or 15 inches long. I would have gladly paid more to get a longer exhaust tip. Very smart looking on my Explorer and it really dresses it up.

Smart grid communications: BPL spec gets the go-ahead
By: SGN Staff
Quick Take: With all the noise about wireless communications such as RF mesh and cellular, it is easy to forget that powerline communications (PLC) is still the preferred method in many parts of the world. Indeed, the PLC market is growing by a robust 19% per year, according to new research from MarketsandMarkets.
Meanwhile, the upper end of the powerline family - broadband over powerline (BPL) - has just received a stamp of approval from the Smart Grid Interoperability Panel (SGIP). The group just voted to include IEEE's BPL spec in its "Catalog of Standards." - By Jesse Berst
The new standard, IEEE Standard for Broadband over Power Line Networks: Medium Access Control and Physical Layer Specifications (IEEE 1901â"¢) includes standards and practices the SGIP "considers to be relevant for the development and deployment of a robust, interoperable and secure smart grid."
Bill Ash, strategic program manager with the IEEE Standards Association, said "Having the SGIP approve the inclusion of our standard in its catalog underscores the importance of smart grid expansion and advancement worldwide. We understand that collaboration among multiple organizations is paramount to the smart grid's success."
The IEEE 1901 standard was created for high-speed communication devices using electric power lines (also known as broadband over powerline). The standard provides data rates above 500 Mbps in LAN applications and is used with transmission frequencies below 100 MHz.
Click the link below for more information on IEEE 1901.
Jesse Berst is the founder and chief analyst of Smart Grid News.com, the industry's oldest and largest smart grid site. A frequent keynoter at industry events in the U.S. and abroad, he also serves on advisory committees for Pacific Northwest National Laboratory and the Institute for Electric Efficiency. He often provides strategic consulting to large corporations and venture-backed startups. He is a member of the advisory boards of GridGlo and Calico Energy Services.

The present invention is directed to a monitor system that measures flight characteristics of at least one object moving in a predetermined field-of-view using at least one fluorescent marker. The system may include a lighting unit with a light filter, at least one camera unit with a camera filter. The lighting unit directs light in the direction of the object. If there is a light filter the light is filtered prior to reaching the object. The camera unit is pointed toward the object and the camera filter inhibits all wavelengths except those in a certain range. The reflected light from the object is transmitted to the camera through the camera filter. In one embodiment, the system includes a camera filter that is electronically switchable between at least two colors. The present invention further includes methods for monitoring at least one object with at least one marker using filters.
1. A monitor system for measuring kinematics of at least one object, comprising:
a light source capable of directing light having a primary excitation wavelength at the at least one object, wherein the at least one object has fluorescent markers with a primary emission wavelength arranged thereon;
a camera;

The present invention relates to a monitor system with optical wavelength discrimination and fluorescent markers. More particularly, the present invention relates to a system for monitoring kinematics of golf equipment and a method for use thereof.
Devices for measuring golf ball flight characteristics and club head swing characteristics are known. For example, the golf ball or golf club head may be marked with at least one contrasting area, used to generate optical images that may be used to determine performance characteristics. Some of these devices use retro-reflective tape or paint markers. Retro-reflective markers, however, result in a raised surface when placed on the golf ball and effect flight performance of the golf ball. It would therefore be desirable to provide a system which measures the launch or flight characteristics of a golf ball using markers that did not substantially effect the flight performance of the golf ball. In addition, paint or ink-based markers and devices are ineffective in bright sunlight and do not provide sufficient optical discrimination of markers.
Devices for measuring two sports objects in a single swing are known, however, these systems have drawbacks relating to outdoor functionality, portability, accuracy, and ease of use. Thus, a need exists for a monitor system to capture club motion data and ball motion data where the system is portable, easy to use, accurate, and adaptable for outdoor use.
The present invention is directed to a method and apparatus for measuring the flight characteristics of an object using fluorescent optical markers. In particular, one embodiment contemplates a monitor system for measuring flight characteristics of an object, such as a golf ball and/or a golf club, with fluorescent markers. The flight characteristics are derived from data taken when the object is in a predetermined field-of-view. The system preferably includes at least a lighting unit with a light filter and at least one camera unit with a camera filter. The lighting unit directs light in the direction of the object. This light is filtered through a light filter or produced from a narrow wavelength light source, e.g., light emitting diodes, to allow only selected wavelengths of the light to contact the object. The filtered light illuminates the object causing the fluorescent markers on the object to exhibit fluorescence, and thus producing a reflected light at a longer wavelength than the light emitted from the light source. The camera unit is pointed toward the object. The camera filter inhibits the passage of all wavelengths except those in a selected range so that only a portion of the reflected light passes through the camera filter and is transmitted to the camera.
In one embodiment, the camera is a CCD camera with about 90,000 pixels or greater. In another embodiment, the camera has about 300,000 pixels or greater. In yet another preferred embodiment, the camera has about 1,000,000 pixels or greater.
The monitor system may further include a second camera unit pointed toward the object. The second camera unit also has a camera filter.
In one embodiment, the camera filter is a band pass filter. The bandwidth of the band pass filter may be about 60 nm or less; preferably about 30 nm or less, and more preferably about 15 nm or less.
The light filter for use with the present invention may be a low pass filter. In one embodiment, the low pass cut off wavelength is at least 10 nm less than the center wavelength of the camera band pass wavelength. In another embodiment, the low pass cut off wavelength is at least 20 nm less than the center wavelength of the camera band pass wavelength. In one embodiment the light filter passes wavelengths of light less than 580 nm. Filters may have transmission of about 50 percent or greater, preferably about 70 percent or greater. In one embodiment, the filter transmission is about 85 percent or greater.
In one embodiment of the present invention, the fluorescent marker is an orange-fluorescent pigment with a peak transmission around about 600 nm. In yet another embodiment, the monitor system also includes a computer that generates data from images produced by the camera units. These images result from the reflected light that reaches each camera through its camera filter.
The present invention is also directed to a combination of an object, having at least one fluorescent marker, and a monitor system. The monitor system includes a discrete wavelength lighting unit and at least one camera unit. In one embodiment, a first light exits the lighting unit through a light filter towards the object so that only a portion of the first light passes therethrough to the object.
Alternatively, a light source that produces discrete wavelengths or a narrow spectrum of light, e.g., light emitting diodes, may be used. The first filtered light illuminates the fluorescent markers to produce an emission of a second light in the direction of the camera unit at a longer wavelength.
In one embodiment, the camera unit includes an associated camera filter through which the second light travels. Only a portion of the second light passes through the associated camera filter, thereby producing a second filtered light transmitted to the camera.
The present invention is also directed to a method for monitoring an object. The method includes the step of providing the object with at least one fluorescent marker. The method further includes directing a first light in the direction of the object, then filtering the light. The filtered light is reflected off of at least one fluorescent marker to produce a second light in the direction of at least one camera unit. One embodiment further includes filtering the second light to produce a second filtered light, and transmitting the second filtered light to the camera unit.
According to another embodiment of the present invention, the invention is a combination of at least two objects and a monitor system for measuring data for the objects in a predetermined field-of-view. The first object includes at least one first marker with a first reflectance spectra. In one embodiment, the second object includes at least one second marker with a second reflectance spectra significantly different from the first reflectance spectra. The monitor system includes at least one camera pointed toward the predetermined field-of-view. Each camera may further include a switchable filter so that at a first time the filter has a first center wavelength and at a second time the filter has a second center wavelength.
The present invention is also directed to a method of calculating club motion data and ball motion data using a monitor system. The method includes the steps of providing a club with at least one first marker with a first reflectance spectra; providing a ball with at least one fluorescent marker; and directing a light in a predetermined field-of-view. In one embodiment, the method further includes the steps of: reflecting the light off the at least one first marker to produce a first-reflected light; filtering the first-reflected light with a switchable filter at a first wavelength to produce a first filtered light; transmitting the first filtered light to a camera at a first and second time; changing the switchable filter to a second wavelength; reflecting the light of the at least one second marker to produce a second-reflected light; filtering the second-reflected light with the switchable filter set at the second wavelength to produce a second filtered light; and transmitting the second filtered light to the camera at a third and fourth time.
The present invention is also directed to a monitor system for measuring data for a club and a ball moving in a predetermined field-of-view. The system includes at least one camera with a filter pointed toward the predetermined field-of-view. Each camera obtains at least two club images in the predetermined field-of-view, and obtains at least two ball images in the predetermined field-of-view. The system may further include a computer to determine club motion data from the club images and ball motion data from the ball images.
The present invention is related to a portable and accurate method and apparatus for measuring golf performance. In particular, the kinematic characteristics of an object are measured, such as a golf ball and a golf club, using at least one fluorescent marker, camera, filter, and central processing unit. The camera, lighting system, and markings on the object allow measurements, at discrete time intervals, of an object's position and orientation in a predetermined field-of-view.
The apparatus includes at least one lighting unit, used to direct light in the direction of the object and filtered through at least one light filter, or otherwise controlled, to allow only selected wavelengths of the light to contact the object, and at least one camera unit, with at least one camera filter, configured to point toward the object. The light illuminates the object to cause the fluorescent markers to reflect light toward the camera. The camera filter allows only a portion of the reflected light to pass through the camera filter and be transmitted to the camera at selected moments in time. Optionally, a narrow spectrum light source may be used to eliminate the need for a filter on the lighting unit. Narrow spectrum light sources preferably include light emitting diodes.
The activation of the system is initiated through the use of a trigger that may respond to object position or sound. In response to the trigger signal, a first image of the golf ball and/or golf club in the predetermined field-of-view is taken. The actuation of the cameras are controlled through shuttering electronics and via strobes used to take a picture of the object several times. For example, if the camera sensing element is active for 1 ms (1000 microseconds (μs)), the strobe may fire two times, preferably once at t=0 and again at about t=800 μs, producing, or "burning" two images of the markers on the camera's CCD. The camera system also includes a computer and monitor to process image data and determines the launch conditions of the object. Alternatively, an electronic shutter may be opened and closed rapidly, and a strobe light, remaining constant, may be used to acquire images of the markers at two discrete time intervals.
In one embodiment, the trigger communicates via an asynchronous protocol with the camera to control activation. In another embodiment, the cameras and strobes are controlled and communicate using an IEEE 1394 bus. Control and communication using the IEEE 1394 bus, or the like, advantageously eliminates complex cables and allows for a compact, lightweight monitor system. Another embodiment includes a wireless communication device, which advantageously eliminates cables and allows for a compact and lightweight monitor system. The wireless communication device enables remote control and visualization of data acquired by the camera system. The equipment for use in such a wireless connection is known in the communications arts. Preferably, the data rate transfer for such wireless transmission is about 5 Mb/s or greater. More preferably, the data transfer rate is about 10 Mb/s or greater. Still more preferably, the data rate transfer is 100 Mb/s or greater. A preferred communication protocol is IEEE 802.11. A cellular network, as well as other wireless networks, may also be used. If the monitoring equipment is connected to a common power source, a system such as the PowerLine system available from Linksys, which also alleviates the requirement for separate communication lines or wires, may be used. The computer and monitor of the camera system may also be connected via a wireless connection. The trigger used in one embodiment of this system is an acoustic trigger.
Although an acoustic trigger is used as the primary example to explain the system of the invention, a position-sensing trigger, e.g., an optical trigger, such as a laser or other apparatus, can also be used to initiate the system. For example, a light beam and a sensor system may be used so that when the golf ball or club moves through the light beam, the sensor sends a signal to the system. When a laser is used, the laser may be arranged such that a trigger is initiated as soon as the ball moves. For example, the laser may be directed or trained toward the teed golf ball and the first image may be taken as or shortly after the golf ball leaves the tee. An example of a suitable commercially available laser-based optical trigger is Model LV-H32 available from Keyence Corporation of New Jersey.
The Camera
The camera used is preferably an electro-optical camera with a light-receiving aperture, shutter, and light sensitive silicon panel. One example of such a camera is discussed in U.S. Pat. No. 5,575,719. Suitable commercially available cameras include, but are not limited to, Sony XCD-X700 (available from Sony Electronics Inc., Park Ridge, N.J.) and DragonFly (available from Point Grey Research, Vancouver, B.C.). A charge coupled device ("CCD") camera is preferred, but TV-type video cameras are also useful. In one embodiment, cameras based on CMOS technology are used. As discussed, the cameras may communicate through and be controlled by an IEEE 1394 bus or the like.
In one embodiment, the camera has a digital resolution of about 90,000 pixels or greater. In another embodiment, the camera has a digital resolution of about 300,000 pixels or greater, preferably, about 1,000,000 pixels or greater.
More than one camera may be used in the present invention. In an embodiment with a dual camera system, for example, the cameras are preferably asynchronous with external triggering capability and each have a digital resolution of about 100,000 pixels or greater, preferably about 500,000 pixels or greater. Additionally, cameras having the digital resolution values described in the preceding paragraph may also be used.
The camera is directed and focused on a predetermined field-of-view in which a golf ball moves and is imaged. The camera has a field-of view larger than necessary to image just a single golf ball. Thus, when using more than one camera, the predetermined field-of-view is the cameras' fields-of-view at the location where the cameras' lines-of-sight intersect. The angle between the cameras' lines of sight should be from about 0� to about 40�, preferably from about 10� to about 30�.
The optical shuttering systems used in the present invention may have an electronic device to successively control, i.e., activate and passivate, the influence of light on the camera. A non-limiting example of such a shutter is a ferroelectric liquid crystal shutter. Preferably, the time required to open and close the shuttering system is less than about 100 μs.
The camera may be electrically connected to a microprocessor and a computer and monitor.
The Camera Filter
The camera may be fitted with a filter to create greater contrast between the illuminated markers and other objects in the field-of-view. The filter used in the present invention is preferably a band pass filter used to inhibit wavelengths of light in selected ranges. The filter used in the present invention preferably has a center frequency, or center wavelength, around about 600 nm. Depending on the bandwidth of the filter used, e.g., 2, 10, 20, 40 nm, also referred to as filter precision, wavelengths of light from about 560 nm to about 640 nm may be allowed through the filter.
For example,
In one embodiment, the camera filter used in the system of the invention is an orange-interference filter preferably mounted in front of the camera(s). Suitable filters include those from Andover Corporation of Salem, N.H. and Edmund Scientific Corporation of Tonawanda, N.Y.
In another embodiment, a switchable filter is used. A recommended switchable filter is electronic and can change from a filter of one color to a filter of a different color in a short period of time. In one embodiment, the switchable filter is an optical filter with colors that are electronically tunable with a response or turning time of less than about 500 μs, more preferably a response time of less than about 50 μs, with no moving parts or vibration. In another embodiment, the switchable filter has a transmissibility about 60 percent or greater, preferably about 80 percent or greater.
In one embodiment, the switchable filter is able to alternate between three primary colors, e.g., an RGB filter that is switchable between red, green, and blue. A Varispec VS-RGB-GP liquid crystal tunable filter may be used to enable switching between a red filter and a green filter in about 250 μs. When a Varispec filter and a black-and-white camera is used, the filter may be mounted in any suitable way as to situate the filter between the camera lens and the camera.
The Lighting Unit
The lighting unit used in the system of the invention may be a dual strobe lighting unit. The strobe light unit includes at least one flash bulb assembly, the related circuitry, and a cylindrical flash tube. Preferably, the circuits used with the strobe light unit are similar to those disclosed in U.S. Pat. No. 6,011,359, the entire disclosure of which is incorporated herein by reference. In one embodiment, the dual strobe lighting unit includes two Vivitar Automatic Electronic Flash Model 283 strobe lights. In another embodiment, the system uses a dual strobe flash unit, such as those available from Unilux Inc., Saddle Brook, N.J. In yet another embodiment, the flash unit is an LED strobe, such as commercially available Model 5380 available from Illumination Technologies Inc., East Syracuse, N.Y. One skilled in the art would appreciate that the lighting units described herein are exemplary of the light sources for use with the present invention without limiting or restricting the use of other light sources.
In one embodiment of the invention, strobe lights are mounted to sequentially direct light, preferably filtered light, onto the predetermined field-of-view. The distance from the lighting unit to the object is preferably about 60 inches or less, and more preferably about 30 inches or less. Short light bursts are desirable to prevent elongation of optical markers. In one embodiment, the duration of the light for a single burst may be less than about 100 μs, preferably less than about 30 μs.
Alternatively, a flash unit with a single bulb and two separate discharge circuits may be used. Once the trigger signals the microprocessor, the strobe lighting unit sets off successive flashes and provides at least two bursts of light separated by less than about 2000 μs. In another embodiment, the at least two bursts of light are separated by less than about 1000 μs.
The energy in a single burst of light may be greater than about 1.5 joules, and more preferably may be greater than about 3.0 joules; most preferably greater than 6 joules.
Preferably, the strobe light communication and control is performed via a wireless connection, an IEEE 1394 bus, or the like. The delay between an external asynchronous trigger signal and the activation of the first light burst, as well as the delay time between successive light bursts, is dictated by software on the control computer and is transmitted to the strobe unit via the wireless connection or 1394 bus prior to activation.
The Lighting Filter
The filter used with the lighting system is mounted in any suitable way in front of the lighting unit to create a first filtered light. It is preferred that the excitation wavelength is distinct from the marker emission wavelength. While one skilled in the art would readily appreciate that there are several ways to accomplish this, one example is using a lighting filter chosen to have a cut off wavelength less than the center wavelength of the camera filter. This allows for definitive contrast between the emission wavelength and the excitation wavelength and, therefore, only the emitted light, i.e., the marker(s), will be imaged by the camera. The excitation light, i.e., the strobe light, would not be able to pass through the camera filter because the wavelength would not meet the filter's pass criteria.
In one embodiment, the lighting filter is a low pass filter with a cut off wavelength of at least about 10 nm less than the lower end of the marker emission wavelength. For example, the low pass filter would have a cut off wavelength of about 10 nm or less than point BW1, as previously described regarding
The excitation wavelength preferably has a peak transmission at a center frequency or wavelength around about 450 nm. Lighting filters of the invention preferably have transmission of about 50 percent or greater, more preferably about 70 percent or greater. In one embodiment, the filter transmission is about 85 percent or greater.
The Marker
Fluorescent markers include pigments or dyes that release electromagnetic radiation while absorbing another form of energy, but cease to emit the radiation immediately upon the cessation of the input energy. For example, the fluorescent markers useful with the present invention may obtain excitation energy from the lighting unit but cease to fluoresce as soon as the lighting unit is no longer functioning. This feature may be beneficial in the present invention. For example, this phenomena enables dual strobing to capture two discrete groups of markers on a single image frame with minimal blurring that might result from a slow decay of fluorescence.
Fluorescent markers may be identified by spectral emission tests. Spectral emission tests may be performed using, for example, the MacBeth Color-Eye 7000A in the specular excluded and UV included modes. Fluorescent markers typically have reflectance values exceeding 100 within the visible spectrum.
When a fluorescent marker is used with the present invention, the marker is preferably made of orange-fluorescent pigment, although other pigments may be used. The orange-fluorescent pigment can be from a variety of sources, for example, those manufactured by Dayglo Corporation of Cleveland, Ohio, Binney & Smith of Easton, Pa. (LIQUITEX�), and Kuretake Company of Japan.
The marker(s) can be applied to the golf ball or golf club using any suitable method known to those of ordinary skill in the art, e.g., pad printing, foil transfer, marking pens, and spray painting.
When monitoring a golf club and a golf ball simultaneously, it is preferred that the markers for the club and ball are distinguishable from each other. This may be accomplished by using markers of different sizes, shapes orientation, peak optical reflective wavelengths, or any combination thereof. Additionally, different types of markers for the club and the ball may be used. For example, the club may be marked with a fluorescent marker and the ball may be marked with a retro-reflective marker. Another example would be to use a diffuse-reflective circular marker on the ball and a triangular fluorescent marker on the club.
In one embodiment, the club marker has a first reflectance spectra and the ball marker has a second reflectance spectra. In another embodiment, the first reflectance spectra has a first primary response wavelength and the second reflectance spectra has a second primary response wavelength. In another embodiment, the first and second primary response wavelengths are separated by about 50 m or greater. In yet another embodiment, the first and second primary response wavelength are separated by about 100 nm or greater. In one embodiment, the first primary response wavelength is 500 nm or greater, and the second primary response wavelength is about 600 nm or greater.
At least one marker should be used on the golf equipment, although it is preferred that at least two markers are used. In general, the markers should be positioned so that they reflect light from the golf ball or club in the predetermined field-of-view back to the camera(s) used to capture the images. In one embodiment, six or more markers are used on a golf ball and three or more markers are used on a golf club.
The placement of the markers on the golf ball or club can be changed in ways known to those of ordinary skill in the art. A non-limiting example, shown in
Golf balls spin when struck with a golf club, and at some angle of rotation the pattern of markers 60 a-f will yield identical images. Calculation of spin rate is accomplished by computing the angular rotation of a ball through the use of at least two images of the ball taken at a known time interval. If the ball rotates through one of the symmetric orientations during the interval, then errors will occur in calculating the rotation angle and, consequently, in the computed spin rate. A typical pattern of markers is symmetric when rotated through and an angle of 72�. Therefore, use of a pattern of markers that enlarges the rotation angle between symmetric images would be beneficial. Preferably, the pattern is symmetric only after being rotated through an angle of rotation for symmetric images α that is greater than 72�.
Another non-limiting example of marker placement, shown in
As shown in
The Monitor
The monitor used in the system may be an electronic character or graphical display that can be viewed outdoors. In one embodiment, the monitor display has an optical intensity of at least 500 candela per square meter (nit). The display may also be a liquid crystal display (LCD) or light-emitting diode (LED) display. In the embodiment using the LCD, the LCD preferably utilizes super twisted nematics (STN) or thin film transistor (TFT) technology.
In one embodiment, a touch screen is used to overlay a bright LCD panel. The operation of the touch screen system is based on capacitive, resistive, or optical techniques. In this embodiment, the operator may use the touch screen to display, store, or send collected kinematic data or to adjust system parameters prior to and after collecting the kinematic data.
Wireless Connection
In use, the camera unit and lighting unit are placed near the person being measured. The monitor and computer may preferably be located a distance away from the golfer. A preferred embodiment of the invention includes a wireless communication device so that wires or cables do not have to be connected between the equipment positioned adjacent the golfer and the equipment controlling the system and displaying the measured data. The wireless communication device enables remote control and visualization of data acquired by the camera system and eliminates complex cables and allows for a compact, lightweight monitor system. This setup advantageously allows the system to be used in a wide variety of locations and conditions. This setup also advantageously facilitates connection to other display devices, such as a large screen for use during demonstrations.
The equipment for use in such a wireless connection is known in the communications arts. Preferably, the data rate transfer for such wireless transmission is greater than 10 Mb/s. Still more preferably, the data rate transfer is greater than 100 Mb/s. A preferred communication protocol is IEEE 802.11. The computer and monitor of the camera system may also be connected via a wireless connection.
The System
Preferably, the system of the invention weighs less than about 50 pounds and more preferably weighs less than about 25 pounds. In addition, preferably, the physical volume of the system is less than about 2 cubic feet. The entire system 10 (i.e., the camera, filters, lighting unit, central processing unit, and display) may be contained within a single housing capable of being carried with a handle 10 a (shown in
One suitable arrangement of the system, a portable, dual-camera monitoring system, is shown in
Monitoring system 10 includes a lighting box 40 and camera units 36, 38. In this embodiment, the lighting box 40 contains a centrally disposed trigger 41 and a dual strobe lighting unit 42. In other arrangements of the system, the trigger may be separate from the lighting unit. Filter 44 is disposed in front of the dual strobe lighting unit 42. Cameras 36, 38 are directed to the predetermined field-of-view, for example toward golf ball 60. Camera filters 50 a, 50 b are disposed in front of cameras 36, 38.
A single camera system is similar to system 10, however, the system includes a single camera unit, a single filter, an adjacent trigger contained in a lighting box, and a light source.
A ball camera and club camera system allow for simultaneous golf club and golf ball monitoring.
The system is similar to system 10, however, the system may also include a club monitor, a ball monitor, a microprocessor, and a computer and monitor. The club monitor includes a first club camera, a spaced second club camera, and a lighting box. Club filters are disposed in front of each club camera. The club monitor further includes a strobe light unit and a trigger within the lighting box. The ball monitor is similar to the club monitor and includes a first ball camera, a spaced second ball camera, and a lighting box. The ball monitor further includes a strobe light unit within the lighting box and ball filters are disposed in front of each ball camera.
In this arrangement, the club filters are preferably different colors from the ball filters. For example, the club filters can be red and the ball filters can be green. Such club filters allow the club cameras to view the strobe flashes, as reflected from the markers, in a red wavelength and such ball filters allow the ball cameras to view the strobe flashes, as reflected from the markers, in a green wavelength.
Another arrangement of the system, detailed in U.S. patent application Ser. No. 09/782,278, includes a strobe lighting unit with four capacitors and at least one camera unit that is preferably a black-and-white CCD camera with a switchable filter with placement in front of the camera, as previously discussed. This arrangement includes at least one club motion sensor, the number of sensors corresponding with the number of cameras. The sensors are preferably photoelectric sensors manufactured by Tritronics and preferably used with a reflective mount as described in U.S. patent application Ser. No. 09/782,278.
Launch monitoring system 210 further includes first and second camera units 236, 238, a centrally disposed control box 240, and a dual strobe lighting unit 242. First and second camera units 236, 238 are preferably ELECTRIM EDC-1000U Computer Cameras from Electrim Corporation in Princeton, N.J. Charge coupled device or CCD cameras are preferred but TV-type video cameras are also useful. The angle between the two cameras' line of sight is preferably in the range of 10�-30�, with 22� being most preferable. Each of the cameras 236, 238 has a light-receiving aperture, shutter, and light sensitive silicon panel 239. The cameras are directed and focused on a predetermined field-of-view in which a golf ball moves and is imaged. A trigger 272 may be included with system 210.
The control box 240 communicates via a communication method discussed above with the camera units 236, 238 to control their activation and the dual strobe lighting unit 242 to set off the successive flashes. Dual strobe lighting unit 242 includes two strobe lights mounted on top of one another. These strobe lights sequentially direct light onto a beam splitter 243 and then out of the unit through windows 244 and 246 to reflective elements or panels 248, 250 and then to the predetermined field-of-view. Panels 248, 250 may be plates formed of polished metal, such as stainless steel or chrome-plated metal. Other light reflective elements may also be used without departing from the spirit or scope of the invention. Each reflective panel 248, 250 includes an aperture 252, 254. Cameras 236, 238 are fixed on support structure 256, 258 and are thereby disposed with their respective lenses 260, 262 directed to the predetermined field-of-view through apertures 252, 254. Video lines 264, 266 feed the video signals into control box 240 for subsequent use.
The locations of the strobe lights, beam splitter, reflective elements and cameras allow the light directed from the strobe to enter the field-of-view and be reflected back from the ball, due to the reflective dots, to the camera lenses through the apertures. In another embodiment, ring-shaped strobe lights can be used which surround each camera lens. Since the ring-shaped strobe lights are positioned close to the lenses and the center axis of the strobe is aligned with the center of the lenses, the light once reflected off the markers would enter the lenses. Thus, eliminating the need for the reflective elements.
Preferably, telescoping distance calibrators 268, 270 are affixed to support structure 212. The telescoping members are used in calibrating launch monitoring system 210 at the appropriate distance from an object to be monitored. Distance calibrators 268, 270 are extendable members for example conventional radio antennae can be used. Calibrators 268, 270 are used in conjunction with a calibration fixture 370, shown in
Launch monitoring system 100 includes a base or support structure 112 that may also have a cover 113. Slide members or pads 114, 116 are utilized at a lower front portion of support structure 112 and include notches 118, 120 for receiving a rod 190 along which pads 114, 116 may slide. As shown in

Calibration and Operation
The general calibration and operation of the system is shown in
After starting up the system, calibration begins to define the coordinate system to be used by the system (Step S102). The details of the calibration step are disclosed in U.S. patent application Ser. No. 09/468,351, now pending. For example, a single camera system may be calibrated through calculation of the distance between dots.
Optional telescoping distance calibrators 64, 66 may also be used in the system 10, as shown in
After the system is calibrated, operating parameters are defined (Step S103), i.e., left- or right-handed orientation depending on the golfer to be tested. The selection of the left-handed orientation requires one set of coordinates to be used for the left-handed golfer while the right-handed system requires the use of another set of coordinates. Step S103 also involves setting the system in either test or demonstration mode. If the test mode is selected, the system saves the test data. In the demonstration mode, the system does not save the data. Additional data specific to the location of the test and the golfer is entered during Step 103. The operator may optionally enter data for ambient conditions, e.g., temperature, humidity, wind speed and direction, elevation, and type of turf to be used in making the calculations for the golf ball flight, roll, and total distance. The operator may also optionally input the personal data of the golfer, e.g., name, age, handicap, gender, golf ball type, and golf club used (type, club head, shaft).
After this data is entered, the system is ready for data collection or demonstration (Step S104). Steps S105-S107 involve the use of several algorithms stored in the system computer to determine the location of the golf ball and/or golf club relative to the monitor. After the computer has determined the location of the golf ball or club from the images, the system (and computer algorithms) determine the launch conditions. These determinations, which correspond to Steps S105, S106, and S107, include locating the bright area(s) in the images, determining which of those bright areas correspond to the marker(s) on the golf ball, and, then using this information to determine the location of the golf ball from the images, and calculate the launch conditions, respectively.
The use of the system may be explained using the dual-camera system of
A marked golf ball 60 is shown as described according to
At Step S105, the system analyzes the images recorded by a silicon panel in the camera, by locating the bright areas in the images.
Although the marker pattern of
Specific to the ball camera and club camera arrangement, Step S104, involves a first swing sensor that sends a signal to the microprocessor to tell the computer to "arm" the ball cameras, during the club back swing, so that they are ready to fire when signaled. "Arming" the ball cameras clears and readies the panel within the CCD camera to be activated. The arming of the ball camera prior to taking images is due to the particular cameras used. If other cameras are used that more quickly clear and ready the panel, this step and an additional sensor may not be necessary. The signal is also sent to the microprocessor so that it is ready for the signal from a second swing sensor.
After the ball cameras have been "armed", the second sensor causes the club monitor to strobe twice and produce light in the direction of the club on the club downswing. The light reflects off the club markers 72 a-c, at positions A and B as shown in
Graphical representations of the pixel maps for the club cameras are shown in
The ball and club markers are preferably arranged as discussed above and shown in
Referring to the system using switchable filters briefly outlined above, and explained here using two cameras 36, 38, Step S104 begins with the operation of a first club motion sensor when the club 72 moves through the player's back swing. The sensor sends a signal to a microprocessor to tell the computer 70 to open the shutter of the cameras 36, 38 that are stereo-viewing the scene. The signal is also sent to the microprocessor to prepare for the signal from a second club motion sensor.
On the downswing, the beam from second club motion sensor is broken and a strobe light flashes twice. With each light flash from the strobe lighting unit 42, electrical energy from a capacitor is drained, in particular, the downswing drains the electrical energy from two of the four capacitors. The light reflected off the club markers 72 a-c is filtered by the switchable filters in a corresponding filter mode (e.g., red retro-reflective club markers and a red filter). A trigger 41, i.e., a microphone, senses the sound of the collision of the golf club 72 with the golf ball 60 and provides a signal to the microprocessor to switch the filter from the first filter to the second filter, i.e., converts from red to green, or from "on" to "off".
After the filters are switched, a sequence of two flashes of light are then fired by the strobe light from the electrical energy stored in the remaining two capacitors. The light of the last two strobe flashes reflect off the reflective markers 60 a-f on the golf ball 60, are filtered by the second filter, and then transmitted to the cameras 36, 38. The use of the second filter allows the club markers 72 a-c, also included in the field-of-view, to be filtered out of the image. As previously discussed with respect to system 10, this arrangement of the system captures two images of both the club 72 and ball 60.
The system can then determine which of the bright areas correspond to the markers at Step S106. This analysis, which can be done in several ways, is discussed in detail in U.S. patent application Ser. No. 09/468,351, now pending.
If the correct number of dots are found in the image, the system moves on to step S107 to determine, from the dots in the images, the position and orientation of the golf ball and/or club during the first and second images. However, if there are more or less than the expected dots or bright areas found in the images, Step S108 allows the operator to manually filter the images. If too few bright areas are located, the operator may adjust the image brightness, and if too many bright areas are present, the operator may delete them. In some instances, the bright areas in the images may be reflections off of other parts of the golf ball or off the golf club head. If it is not possible to adequately adjust the brightness or eliminate those extraneous bright areas, then the system returns the operator to Step S104 to have the golfer hit another golf ball. If the manual editing of the areas is successful, however, then the system goes to Step S107.
At Step S107, the system uses the identification of the markers in step S106 to determine the location of the centers of each of the markers in the images. Knowing the location of the center of each of the markers, the system can calculate the golf club's speed, loft angle, attack angle, path angle, face angle, droop angle, loft spin, face spin, droop spin, and hit location. In addition, the system can calculate the ball's velocity, launch angle, backspin, side angle, side spin rifling spin, carry distance, direction, carry and roll distance. Detailed information regarding the analysis of the images is in U.S. application Ser. No. 09/782,278.
After the spin rate, velocity, and direction are calculated, the system uses this information, as well as the ambient conditions and the golf ball information entered at Step S103 to calculate the trajectory of the golf ball during the shot (Step S109). The system estimates where the golf ball lands or carries, how far it rolls, and gives a total distance for the shot. Because the system is calibrated in three dimensions, the system also is able to calculate if the golf ball has been sliced or hooked, and how far the ball is off line, as discussed in U.S. Pat. No. 6,241,622.
This information (i.e., the golfer's launch conditions) is then presented to the golfer at Step S110, in numerical and/or graphical formats. At Step S111, the launch conditions can be modified to calculate the same information but for the hypothetical use of a different golf ball (e.g., two-piece as compared to a three-piece golf ball). It is also possible to determine the effect a variation in any of the launch conditions (e.g., golf ball speed, spin rate, and launch angle) would have on the results.
Step S112 provides the golfer the option to take more shots by returning the system to Step S104. For example, if the system is in test mode and the golfer takes a variety of shots, Step S113 can calculate the average of all shot data accumulated during the session. Step S114 provides ideal launch conditions for the golfer's specific capabilities, thereby allowing the golfer to make changes and maximize distance. After completing the session, Step S115 allows the golfer to start a new test with a new golf club or to end the session at Step S116.
Thus, the system of the invention can be used to determine the kinematics of two colliding objects, where the measured kinematics data may be compiled into a database and the database can be accessible to a large user group via the internet or internet networks of computers that are linked in a conventional manner. The present invention is also directed to a computer providing on-course kinematic data acquired by the present system. This data may be posted on a computer and transmitted via the internet or intranet computer networks. This data may be provided, for example, for a fee that the computer may process. The data could also be sent from a golf pro shop to a club or ball manufacturer for equipment purchases or recommendations for a specific golfer.
While the above invention has been described with reference to certain preferred embodiments, it should be kept in mind that the scope of the present invention is not limited to just these embodiments. One skilled in the art would recognize numerous variations of the embodiments described herein without departing from the spirit and scope of the invention. For example, the system could be battery operated or include more than two cameras. In addition, the operating system could be an embedded computer or controlled with programmable logic controllers (PLC). Different markers or paints are possible, as well as the use of laser diodes with a narrower light range to avoid the use of filters. The invention may also include remote capability based on radio or infrared frequency. In addition, features of one embodiment can be combined with features of another embodiment. One skilled in the art may find other variations of the preferred embodiments which, nevertheless, fall within the spirit of the present invention, whose scope is defined by the claims set forth below.

Just and update:
they discovered a hole in LO's lungs last week. They've been monitoring it and draining it but keeps getting worse. This is apparently the reason he's been aspirating, having apnea spells and having "foggy" lungs. Anyhow, they did an operation yesterday. Didn't go too well and he coded. He had to be resuscitated a few times and transfered to another hospital. He is now in a medically induced coma while the doctors figure out a way forward. There have been talks of signing a DNR but we are not ready to give up just yet, but I'm not too sure for how long these feelings will last. Would you sign a DNR on LO's life? This was suggested at the first hospital but we are almost half expecting these guys to suggest it as well.
We joke that since our initial NICU stay was very uneventful, the problems of prematurity are finally catching up to us. Although we say it as a joke I'm pretty sure we all mean it to some degree. I can only hope that this is the last major hurdle we have to overcome.
Please HUG and KISS your LOs every chance you get. You never know what tomorrow brings
Lots of Love

Tommy Lee Sparta released yesterday his Ep titled – Grim Reaper – for U.I.M Records that features some of his best hits and some new tracks. Leroy Russell aka Tommy Lee Sparta the young Gaza DeeJay from Flankers – Mobay -is setting new records with the speed of light inna Dancehall, like his homie , legendary Usain Bolt in the running fields, and… it's all happening quick quick quick.
Listen to Tommy Lee Sparta Ep – Grim Reaper – U.I.M. Records -October 2012
It's been since the release of one of his recent singles -Psycho and after his performance at Reggae Sumfest this past summer,in his native Mobay, that the young artist's popularity has been growing non – stop so fast, so big that everybody is talking about his music and the different flavor the Sparta's vision brought inna Dance Hall. While some people can get him yet and tryed to label him as demonic, this artist is making some real noise internationally too, there's a lot of attention,all eyes and hears on him type of situation, even from the mainstream medias in America.This is a BIG WEEk for Uncle Demon: the EP release and an article on The Fader Magazine.
So it happened that The Fader Magazine, out on newsstands next week, came out with a story on the Sparta written by Jesse Serwer. To understand the potential of this artist to the fullest it has to be first clear that very few Jamaican artists are getting coverage in mainstream magazines since Dancehall is said to be less popular internationally now, and magazines are getting smaller. Few artists had that type of honors in current times. Vybz Kartel, Mavado,… Popcaan and now Tommy Lee Sparta. This is pretty big for Uncle Demon because it's a first major international magazine's article (not a blog post but real paper magazine that people actually buy in major numbers at the news stands).

The Culture of Sharing: Join Us For #YamJam12 Tweetchat on Wednesday!
In anticipation of YamJam 12, our first annual conference, we drew together some of our amazing speakers for a public tweetchat last week. The goal of this meeting of the minds was to address tactical adoption advice, as well as high-level commentary around The Future of Work. Joining us were: Ray Wang and Alan Lepofsky of Constellation RG, Adam Pisoni of Yammer, Miguel Zlot of Molson Coors. Check out the Storify recap below for highlights.
We had a great time discussing the future of work, and wanted to continue the conversation talking about The Culture of Sharing — a culture that fuels and makes successful efforts in enterprise social. We are doing another tweetchat this week, featuring a fresh and equally big topic, with a new cast of featured speakers. We'll be discussing why organizational sharing is important to help you move with velocity, and what you can do to make it less scary to share. Join Michael Fauscette of IDC, Roland Hulme of Tyco, Lawrence De Voe of Initiative and Jonathan Anthony of Teekay on Wednesday, October 24 at 12 noon PST / 3 p.m. EST.
We will be addressing questions like:
- Why is sharing important?
- How sharing be encouraged at an organizational
- Why are top-down hierarchical organizations hesitant to encourage sharing?
- How does sharing translate into a culture of transparency?
- What does sharing mean for execs, middle managers and users?
- How does "working out loud" help you avoid costly mistakes?
What do you want to know? Ask a question in the comments or show up to the tweetchat!
To participate, follow hashtag #YamJam12 and bring your brilliant comments and questions. We'll be giving away a few free tickets to YamJam '12 to a few lucky participants who contribute thoughtfully!
Update! We had SO much great insight from all those who participated. Check out some of the best Culture of Sharing tweets:

Apple, others sued over Bluetooth usage
updated 12:15 pm EDT, Wed March 28, 2007
Apple sued over Bluetooth
Apple and seven other tech companies were added to a lawsuit filed over Bluetooth patents, potentially threatening the company's use of the technology in its products. The Washington Research Foundation -- which filed suit against Matsushita Electric Industrial, Nokia Oyj, and Samsung Electronics in December over Bluetooth technology in a federal court -- has added Apple, Dell, Logitech International, Motorola, Plantronics, Sony, and Toshiba as defendants in the case, according to Bloomberg. The companies are accused of infringing on four patents that describe data exchange between mobile phones, personal computers, and other devices without cables. Apple has built Bluetooth functionality into its Mac OS X operating system, and allows customers to configure Macs with Bluetooth hardware.
