1. Technical Field
The present invention pertains generally to microwave powered lamps and, more specifically, to improvements in methods and apparatus for mounting optical reflectors in microwave cavities defined by a screen structure employed to transmit light while retaining microwave energy.
2. Discussion of the Prior Art
Lamps utilizing radio frequency (RF) energy to excite electrodeless bulbs are well known. Examples of such lamps may be found in U.S. Pat. Nos. 4,954,755 (Lynch et al), 5,227,698 (Simpson et al), 5,334,913 (Ury et al) and 5,404,076 (Dolan et al). The disclosures in all of these patents are expressly incorporated herein. In lamps of this type microwave energy is coupled from a magnetron or other RF source to the lamp bulb via a coupling circuit including a waveguide and a quasi-resonant cavity typically defined, at least in part, by a screen unit. The waveguide functions as an impedance matching device from the source to the cavity.
Prior art screen structures used in microwave powered lamps are disclosed in numerous prior patents as represented by the above-mentioned Lynch et al, Simpson et al, Ury et al and Dolan et al patents, and in European Patent Specification 0 153 745 (Yoshizawa et al). Such screens typically surround a bulb envelope and serve to allow optical radiation from the bulb to escape while forming a conductive enclosure blocking escape of RF energy. Screen design has generally involved an inherent compromise between these factors. Specifically, screens having very low optical loss tend to permit escape of undesirably large amounts of RF radiation. On the other hand, elimination of RF radiation generally incurs the penalty of diminishing optical transmission through the screen.
A recent development in screen structure is disclosed in U.S. patent application Ser. No. 08/592,474, filed contemporaneously herewith by Brian Turner and Michael Ury and entitled "Microwave Container Screens for Electrodeless Lamps" (attorney docket FUS961). The entire disclosure from that patent application is incorporated herein by reference. The screen structure disclosed in the Turner and Ury patent application includes a metal mesh section and a metal solid section. The mesh section is transmissive to light and non-transmissive to microwave energy at the operating frequency. The solid section is non-transmissive to both light and microwave energy. In this regard, the term "solid" as used herein is intended to distinguish from the mesh section and connotes the absence of gaps or breaks in the structure. The mesh section has a right cylindrical configuration with a mesh end cap at one end, and the solid section is configured as a right cylindrical section of like diameter extending coaxially from the opposite end of the mesh section. A reflector, in the form of an electrically non-conductive circular disk, has its annular edge secured at the annular juncture between the mesh and solid sections, and is disposed coaxially with both of these sections with its reflective surface facing into the mesh section. The reflector thus defines an optically isolated light transmission chamber within the microwave cavity. An electrodeless bulb has its discharge envelope disposed within the light transmitting cavity surrounded by the mesh section. The reflector is centrally apertured to permit passage of the bulb stem through the space bounded by the solid section of the screen unit.
The screen unit is fabricated from two members, the first of which is a single thin rectangular sheet of stainless steel that is etched to provide the desired mesh pattern. The sheet is rolled into a cylinder to form the screen member containing both mesh and solid sections.
The reflector is essentially a mirror made from fused silica coated with a metal oxide dichroic coating which does not absorb microwave energy. The mirror can be mounted in various positions in the cavity depending upon the optical design. Once mounted it must retain its position regardless of orientation to gravity, shocks experienced during shipping or operation and continued vibration over many years of use. The mirror is subjected to very high temperatures because it is disposed adjacent a bulb operating at temperatures in excess of 800� C. and emitting over 600 watts of radiation. Any mirror mounting system must not absorb microwaves or add dielectric volume to the cavity, and must be able to withstand a high temperature (e.g., 300�-500� C.) environment.
The reflector described in the aforementioned Turner and Ury patent application is held in place with a high temperature cement called Saurereisin™ brand cement a white hard cement which adheres reasonably well to glass and to the stainless steel screen material. Three or four dabs of cement are placed around the edge of the reflector glass where it touches the screen material. This technique works reasonably well but requires fixturing the mirror in place while the cement dries, usually an overnight procedure. The process tends to be messy and labor intensive in order to put the right amount of cement on the reflector edge. In addition, the technique is subject to occasional bond failures.
It is therefore an object of the present invention to provide a method and apparatus for quickly, inexpensively and reliably mounting a reflector in a microwave cavity formed by a thin metal screen unit used in a microwave powered electrodeless lamp.
In accordance with the present invention, an optical reflector is secured in place between two rows of bendable tabs or other members defined in a cavity-forming screen of the type disclosed in the Turner and Ury patent application. Specifically, the screen unit, which is made from a thin sheet of etched stainless steel, has the desired tab patterns etched into the metal sheet preferably at the same time the mesh portion of the screen is etched. The tabs are defined by etching generally U-shaped cut-outs in the metal sheet. Upper tabs, defined in an annular row at circumferentially spaced tab locations, are adapted to be bent downward out of the plane of the sheet at an angle of 90� so as to extend radially inward of the cylindrical screen unit. The reflector, typically in the form of a circular disk, is inserted through the bottom of the cylindrical screen against the bent upper tabs. Lower tabs, defined in an annular row at positions circumferentially spaced about the screen periphery, are then bent upward to engage the reflector in place between the two rows to tabs. The spacing between the two rows is substantially equal to the thickness of the reflector disk.
Bending of the upper tabs downward can be effected by a fixture placed inside the cylindrical screen to ensure a sharp 90-degree bend. The tabs themselves are rounded at their distal ends to minimize any field enhancement that might be caused by the radial projection of the metal. In addition, the tabs must be sufficiently short to avoid coupling of energy from the microwave field in order to prevent arcing from the tab edges.
Multiple rows of tabs can be defined in the screen in order to provide several alternative positions for the reflector. The tabs may be formed in either the mesh pattern or the solid pattern of the screen unit. As an alternative to tabs, any members defined in the screen and capable of being projected into the cavity may be utilized to mount the reflector.
The above and still further objects, features and advantages of the present invention will become apparent upon consideration of the following detailed description of specific embodiments thereof, particularly when taken in conjunction with the accompanying drawings wherein like reference numerals in the various figures are utilized to designate like components.

FIG. 6 is a detailed top view in plan of a portion of the sheet of FIG. 5.
FIG. 7 is a detailed top view in plan of a portion of an alternative sheet configuration used to form a screen assembly of the present invention.
Referring specifically to FIG. 1, a lamp assembly using the screen unit of the present invention includes a lamp module 10 comprising a housing for a magnetron 11 or other microwave source, a filament transformer 13 supplying filament current to the magnetron 11, and a motor 15 for rotating a bulb and for driving a cooling fan in the form of blower wheel 17. An air inlet 19 is defined in one end of the housing, and blower wheel 17 causes air to flow through the lamp module 10 to an air outlet, as shown in FIG. 1.
A screen assembly 20 defines a microwave cavity wherein a bulb 21 is disposed. Bulb 21 includes a generally spherical discharge envelope 23 (also shown in FIG. 3) supported at the end of an elongate cylindrical stem 25. Stem 25 is secured to a drive shaft 27 of a motor 15 to permit the bulb 21 to be rotated about the longitudinal axis of its stem 25. Bulb 21 has a high pressure fill material contained in its discharge envelope 23 such as, for example, the material described in the above-referenced Dolan et al patent. The bulb is made of quartz or other suitable material.
Microwave energy generated by magnetron 11 is fed by a waveguide 27 to a coupling slot 29 providing ingress to the microwave cavity defined by screen unit 20.
The screen unit 20 of the preferred embodiment is made from two members, namely a right cylindrical member 30 and an end cap 40 (see FIGS. 1-3). Each of these two members is formed as a respective one-piece unit. Specifically, cylindrical member 30 is formed from a single sheet 41 (see FIG. 5) of metal that has been etched to provide a metal mesh section 42 and a contiguous metal solid section 43 (see FIGS. 1-5, also denoted by "RF SCREEN" in FIG. 1). In addition, an upper row of mounting tabs 47 and a lower row of mounting tabs 48 are etched into sheet 41 simultaneously with the etching of mesh section 42 (see FIGS. 4 and 5). In the preferred embodiment the upper tabs 47 are defined in mesh section 42 whereas the lower tabs 48 are defined in solid section 43. As seen in FIG. 6, the tabs are generally U-shaped and co-planar with sheet 41, and are defined by etching a U-shaped slot through sheet 41 about each tab location. The upper tabs 47 extend upwardly while the lower tabs 48 extend downwardly. Typically, right tabs are defined in each row at equally spaced circumferential locations about screen unit 20 with the tabs in each row being offset circumferentially from the tabs in the other row. In the preferred embodiment each tab 47 is located circumferentially midway between tabs 48.
An imaginary circumferential line joining the roots or bases about which tabs 47 are bendable is longitudinally spaced from a similar imaginary line joining the base of tabs 48. The spacing is selected to match the thickness of a reflector 50 (see FIGS. 1, 3, 4; also denoted by "MIRROR" in FIG. 1) described below.
Preferably, sheet 41 is a stainless steel sheet having a thickness between 0.003 and 0.005 inches. Mesh section 42 and tabs 47, 48 are etched through the sheet, the etching pattern preferably being controlled by computer so that virtually any location of the tabs and mesh section or sections and any pattern and size of the tabs and the interstices of the mesh can be provided. The size and pattern of the interstices are selected to minimize transmission of RF energy through the conductive mesh. As shown in FIG. 5, in the preferred embodiment mesh section 42 and solid section 43 are formed in sheet 41 as adjacent or contiguous rectangular sections meeting at a straight line juncture corresponding to the abutting inboard edges of these two sections. The rows of tabs 47, 48 are defined on opposite sides of this juncture. The three outer edges of mesh section 42 are bounded by a very narrow solid metal border or strip 44 (see FIG. 5) formed as a continuance of solid metal section 43. The longer outer edge of solid section 43 has multiple slots etched therethrough and extending perpendicular to that edge toward mesh section 42. These slots define multiple finger-like members 45 which, because of the thinness of the material of sheet 41 and the spacing of the slots, are individually compliant to facilitate attachment of the screen unit to the assembly in the manner described below.
As seen in FIGS. 2 and 3, during assembly sheet 41 is rolled into a right circular cylinder such that mesh and solid sections 42 and 43 form respective adjacent cylindrical sections for the resulting screen unit 20. In order to maintain the final cylindrical form of the rolled sheet, opposite edges of the sheet are slightly overlapped, i.e., by the width of border 44 (see FIG. 3), and then secured together by any suitable means such as adhesive, welding, etc. In the resulting cylinder 30, the end comprising fingers 45 defined in solid section 43 is referred to herein as the proximal end of the cylinder; the opposite end, bounded by the annular portion of border 44 of mesh section 42, is referred to herein as the distal end.
As shown in FIG.3, end member 40 is a substantially circular mesh member formed from the same material and by the same process as cylindrical member 30. The mesh end member 40 is circumferentially bounded by a solid border 46. Border 46 and the annular portion of border 44 of cylinder 30 are joined together by crimping, welding or other suitable technique to provide a mesh closure at the distal end of the cylinder.
As best illustrated in FIGS. 3 and 4, a reflector 50 takes the form of a circular disk having an outside diameter substantially equal to the inside diameter of cylindrical member 30. Reflector 50 is typically made from fused silica and has at least one surface 51 (see FIGS. 1,2,3,) with an optically reflective metal oxide coating which does not absorb microwave energy. A small centrally located aperture 53 is defined in reflector 50 and is of sufficient size to permit stem 25 of the bulb 21 to pass therethrough. Reflector 50 is positioned coaxially within the microwave cavity at a location corresponding to the annular juncture of mesh section 42 and solid section 43. In this manner reflector 50 effectively defines an optically isolated light transmission chamber by optically closing off the proximal end of mesh section 42 from the remainder of the microwave cavity without affecting the quasi-resonant characteristics of the overall cavity at the operating microwave frequency. Attachment of reflector 50 to the cylinder is achieved according to the present invention in the manner described immediately below.
In order to mount reflector or mirror 50 in the microwave cavity, the upper tabs are each bent 90� downward and inward about their bases so as to project radially into the cavity and define a first support plane. This bending can be by hand but is preferably done by using a suitable fixture placed inside the screen to assure a sharp 90-degree bend. Reflector 50 is then inserted through the bottom opening of screen unit 20 (i.e., through the opening at the proximal end of the unit where solid section 43 is located). The reflector disk, having an outer diameter corresponding to the inner diameter of screen unit 20, is thus able to be seated with its top reflective surface against the bent upper tabs 47. The lower tabs are then bent 90� upward and inward about their bases so as to project radially into the cavity and against the bottom surface of reflector 50, thereby defining a second reflector support plane. The spacing between the two support planes substantially corresponds to the thickness of reflector 50.
The screen unit is secured to the lamp assembly 10 (see FIGS. 1 and 3) by disposing fingers 45 circumferentially about an annular flange 28 extending from the assembly housing. The compliance inherent in the finger structure facilitates this placement. An annular hose clamp 60 (FIG. 3) may then be placed circumferentially about the fingers and then tightened by radial contraction to secure the fingers to the flange 28. Coupling slot 29 from the waveguide is located radially inward of flange 28 so that the microwave energy from magnetron 11 can be delivered into the microwave cavity defined by screen unit 20, as seen in FIG. 1.
As best seen in FIG. 1 in the assembled unit the bulb discharge envelope 23 is disposed in the optically isolated optical transmission chamber of the microwave cavity defined circumferentially by cylindrical mesh section 42 and at its ends by reflector 50 and end cap 40. Bulb stem 25 extends through aperture 53 in reflector 50 into the opaque chamber bounded by solid section 43, and then through a suitably provided bore in the lamp assembly housing where the stem is engaged by a rotatable drive shaft of motor 15 to permit rotation of the bulb about the stem axis. As is conventional, one of the effects produced by rotation of the bulb in this manner is the cooling of the bulb discharge envelope 23 in the microwave cavity.
Microwave energy entering the cavity defined by screen unit 20 via coupling slot 29 excites the fill in discharge envelope 23 resulting in light energy being emitted from the envelope. Reflective surface 51 prevents the light from entering the region of the microwave cavity bounded by solid section 43 of the cylindrical member 30. Instead, light impinging upon surface 51 is reflected out of the cavity through the interstices in mesh section 42 and end cap 40. Reflector 50, and in particular reflective surface 51, may be contoured as desired (e.g., concave, convex, etc.) to reflect light in preferential directions through the mesh. Clearly, substantially all of the light energy is prevented from passing into the region bounded by the solid section of the cylinder, thereby permitting the light to be most efficiently transmitted out through the interstices of the mesh material. Since the portions of the microwave cavity boundary wall through which light transmission is not desired are solid, the overall RF leakage through the screen unit is greatly reduced from that of an all mesh screen unit.
In an exemplary embodiment of the present invention, a stainless steel sheet 41 is rectangular in shape and has a thickness of 0.102 mm. The length and width of the sheet are 237.13 mm and 125.73 mm respectively. The width of solid section 43 is 41.91 mm, and the width of mesh section 42 is 83.82 mm. Edge border 44 is 1.52 mm wide. Fingers 45 are sixteen in number, extend 10.0 mm into solid section 43 from the edge of sheet 41, are separated by 1.3 mm wide slots and are 13.4 mm wide. Tabs 47 and 48 are 1.27 mm wide and 2.54 mm long, and their defining U-shaped slots are 0.25 mm wide throughout their U-shaped length. The spacing between tabs 47 in the top row, and between tabs 48 in the bottom row is 30.2 mm. The spacing between the bases of the rows of tabs (i.e., longitudinally along the cylinder) is 1.65 mm. It is to be understood that these dimensions are provided by way of example only and are not in any way limiting on the scope of the invention.
The length of tabs 47 and 48 must be limited to prevent them from coupling energy from the microwave field established in the cavity. Such coupling could lead to arcing from tab edges. The 2.54 mm exemplary tab length stated above is considerably shorter than the wavelength of a typical operating frequency of 2.45 Ghz and has proven to be a satisfactory choice for the described embodiment.
In mounting the reflector it may not be necessary to bend all of the tabs into the cavity. For example, only alternate tabs in either or both rows may be deployed in certain instances, thereby further reducing the likelihood coupling energy from the microwave field.
It will be appreciated that more than two rows of support tabs may be etched into sheet 41, thereby providing alternative longitudinal mounting locations for a reflector in the cavity. Moreover, the "rows" need not be defined in straight lines across sheet 41 or parallel to the edges of that sheet, depending, of course, on the configuration of the reflector to be mounted in the microwave cavity. In addition, a pair of supporting tab rows need not be located at the junction of solid section 43 and mesh section 42. Thus, for example, the cooperating tab rows may both be defined in a mesh section 42 as illustrated in FIG. 7.
As noted above, the cylindrical member of the screen unit is preferably fabricated by selectively etching the desired mesh and tab patterns and in a sheet of metal. It will be appreciated that the mesh pattern can easily take any shape consistent with the desired light transmission pattern for the lamp assembly. Of course, the configuration of the reflector can also be changed to provide such light transmission pattern, thereby determining the location and pattern of mounting tab groups. It will be appreciated, therefore, that the cylindrical member 30 can be etched or otherwise formed with any combination of tab patterns and mesh and solid sections from one sheet of metal. By appropriately locating one or more reflectors in the resulting microwave cavity, the optically transmissive chamber of the cavity can be optically isolated from the remainder of the cavity, thereby minimizing RF leakage while optimizing light transmission.
Although the screen unit for the preferred embodiments illustrated herein includes a substantially cylindrical member, it will be appreciated that the microwave cavity, in some instances, need not be cylindrical. In this regard, the same techniques described hereinabove may be utilized to provide screen units having rectangular, polygonal, oval, or other transverse cross-sections, and the tab patterns for mounting suitable reflectors will change accordingly.
The tabs may be used to support a reflector in other types of screens, not only screens having mesh and solid sections etched or otherwise formed in the same sheet. For example, where the screen unit is entirely mesh, the tab approach described herein is equally applicable. Likewise, although tabs constitute the preferred reflector support structure, such structure need not take the form of tabs. Substantially any inwardly projectable deformable portion of a screen unit may be used to mount the reflector. For example, two annular portions of a screen, either mesh or solid, may be radially compressed inward and deformed to define an annular recess for receiving and supporting a reflector. Similarly, portions of the screen may be projected radially outward to define an annular pocket to receive a reflector. Whichever alternative is used, the important feature is that the reflector support structure is formed as part of the same one-piece member in which the mesh is etched or otherwise defined.
It will also be appreciated that the use of built-in tabs or other deformable members to support a reflector as described herein is not limited to the particular etched screen structures disclosed herein. Rather, the reflector mounting techniques of the present invention are useful and adaptable to a wide variety of prior art screen units in which the deformable member can be formed. See, for example, the Lynch et al, Simpson et al and Ury et al patents referred to hereinabove.
From the foregoing description, it will be appreciated that the invention makes available a novel mounting arrangement for a reflector in a screen unit for electrodeless lamps wherein reflector mounting tabs and mesh and solid sections may be defined in a single member used to form the body of a microwave cavity, whereby a reflector can be easily, reliably and inexpensively mounted at a location to optically isolate a light transmission chamber from the remainder of the microwave cavity while reducing microwave energy leakage from the cavity.
Having described preferred embodiments of a new and improved method and apparatus for mounting a mirror in a microwave powered lamp, it is believed that other modifications, variations and changes will be suggested to persons skilled in the art in view of the teachings set forth herein. Accordingly, it is to be understood that all such variations, modifications and changes are believed to fall within the scope of the present invention as defined by the appended claims.

Just two years ago there was an article written by Bob Bauder about this issue- Skyline-defiling signs targeted by council chief. "Harris said the signs, including company names and logos, clutter the city skyline and detract from its aesthetic splendor."
And author Charles Rosenblum's blog post Under a Bad Sign– Pittsburgh Architectual Club weighs in on the issue.
What My Client Lent Me at the Photo Shoot
Remember the Spring-like November Day I posted Tuesday with the thirty degree drop in temps predicted?
Well, it's more like a forty degree drop two days later-
in the park, late afternoon.
Cashmere fingerless gloves.
Thank you SB for the loan of the luxurious gloves. I'm still warming up the rest of me.
My hand looks a bit like "The Claw" in a horror flick but the cozy gloves were so welcome on my chilly hands during the photo shoot in the park.
Life-Size Chipmunk Sighting on Herron Hill
Friday afternoon I drove a colleague to the Strip District to pick up her car. It was raining. She'd gotten new tires.
At the red light, down Herron Hill, I saw a Life Size Chipmunk making her way to the intersection to cross Liberty Avenue. (The same spot I saw the groundhog scurrying under the cars.)
Oh that's right, it was Halloween.
Office Party? Chip or Dale? Alvin? A leftover from the Furries
The city is there, I swear
On the way to school, I drove up McArdle Roadway to Mount Washington.
This is shot from the Duquesne Incline Platform. A blanket of October 1st fog.
Almost a Wordless Wednesday.
Weekly Photo Challenge: Nighttime
Photographing at night is one of my favorite things to do.
The city looks the most beautiful at night.
I scanned just a wee portion of my archives to get a representative sampling.
Nighttime- quiet, dark. Sparkly, twinkly too as I seem to shoot a lot of lights.
Anna and Maura and Henry getting ready to go to sleep.
The city lit up feels magical to me. Every November they have Light Up Night
Goorin Brothers Hat Shop on Bleecker Street, New York City
Inspired by my son-in-law James. A bus on Bryant Street in Highland Park

80 Pounds of Fresh Linguine in a Day
No, not eaten. Made!
I can tell you that it is delicious. Today I was buying walnuts and Amish butter and fresh eggs to make biscotti.
On Tuesday they make ravioli. Mushroom, Imported cheese, artichoke, and many other varieties
Here is Carol in the Groceria Italiana (established 1958) in Bloomfield neighborhood of Pittsburgh.
She is of Irish German descent but is married to an Italian, she told me. Very hospitable and didn't mind my questions at all.
There is a lovely photograph of Gloria who has passed but who made fresh pasta for years and years using these same machines.
One machine is 27 years old.
Thanks for letting me photograph the process with my iPhone. I will return with my good camera one of these days.
Another machine rolling the dough into strips.
Preparing the strips for the machine.
Here the pasta strips are being cut.
Carol can make 80 pounds of fresh linguine in a day!
You can see the different widths on the pasta cutter machine. Gloria's photo is above the machine. Carol said her spirit is with them still.
Hot Town Summer in the City
Back of my neck feeling dirty and gritty.
This is a photograph without a caption other than waiting. One of my self-assignments is to experience more street photography this summer.
Taken with a 100-300mm Canon lens. The old lightweight one. Bought it used for $150 at the Camera Repair store.
Shot through the driver's side glass when I was at a red light. I think I was spotted.

Building Storage for Availability and Survivability
Jon Toigo
Jul 1 2015
46 mins
With software-defined storage taking hold both as a model for building data storage infrastructure behind servers and as a template for designing ready-made hyper-converged server/storage hardware nodes, IT planners confront many options for creating a high performance, cost efficient platform for data hosting. Just as important, however, is the design of storage infrastructure for high availability – to protect against hardware and software glitches – and for survivability – to ensure data accessibility in the face of disasters with a broader geographical footprint. In this Brown Bag webinar, IT-SENSE editor and chief Jon Toigo kicks things off with a discussion of the requirements for building a bullet proof storage infrastructure using software-defined and hyper-converged elements. He will be joined in the Between Two LUNs segment by storage expert Max Kolomyeytsev from StarWind Software to talk about the availability/survivability of StarWind technology and the resiliency of its latest hyper-converged infrastructure product, developed in connection with xByte Technologies.

The 2015 Ethernet Roadmap For Networked Storage
Scott Kipp, President of the Ethernet Alliance; Dave Chalupsky, Chair, IEEE P802.3bq/bz TFs; David Fair, Chair - SNIA-ESF
Jun 30 2015
63 mins
For over three decades, Ethernet has advanced on a simple "powers-of-ten" speed increases, and this model has served the industry well. Ethernet is changing in big ways and the Ethernet Alliance has captured the latest changes in the 2015 Ethernet Roadmap. SNIA is pleased to welcome Scott Kipp, President of the Ethernet Alliance and David Chalupsky, Chair IEEE P802.3bq/bz TFs and the Ethernet Alliance BASE-T Subcommittee to present the Ethernet Alliance's 2015 Ethernet Roadmap for the networking technology that underlies most of future network storage.
SNIA has focused on protocols and usage models and more or less just takes Ethernet for granted. The biggest technology disruption in the storage space is the emergence into the mainstream of Non-Volatile Memory (NVM), FLASH in particular. NVM increasingly moves system bottlenecks from the storage subsystem to the network. Developments in NVM -- most recently 3D FLASH -- assure that the cost per GB will continue aggressive declines and demand for bandwidth will go up. NVM will become more prevalent, making the roadmap for Ethernet increasingly more important to the storage networking community.

Drowning in Data and Starving for Information
Jan 8 2013
45 mins
Stanley Zaffos - VP and Research Director, Gartner and Joey Jablonski - Practice Director, Analytic Services, DDN
The ability to generate and capture various sensor data, communications, and imagery has grown exponentially, and there does not appear to be any change in sight. To effectively extract the maximum benefit from the deluge of data generated today, analysts need to utilize the new generation of analytical tools and human expertise that is rapidly being developed. When properly utilized, these advances are providing today's analysts with an unprecedented ability to make real-time data-driven decisions as well as improved options to collaborate and share information. However, effective implementation in the era of hyperscale data depends on the ability to manage conventional system technology, and unpredictable volume requirements. An imbalanced analytics system can result in bottlenecks that reduce the value of analytics tools and the enterprise data warehouses (EDW) that power them. As such, it's critical for organizations to ensure that at either end of the ingest/egest process they build scalable storage and storage processing technology to complement today's high-speed data warehousing and data analytics technology. This session will detail how new filing system options and cloud infrastructure can improve the performance of analytics applications utilizing actual benchmark tests, and demonstrate new options to collaborate and share information.

Policy-Based Data Management, Integrated Rule Oriented Data Grid (iRODS)
Oct 12 2012
58 mins
Dr. Reagan W. Moore - Director, Data Intensive Cyber-Environments
Higher education institutions around the world are in the process of digitizing, indexing and adding searchable metadata to their digital collections. As these data sets expand to hundreds of millions of immutable objects and petabytes of data, there is a need to consolidate and automate to maximize the value of this capital expenditure.
The Integrated Rule-Oriented Data System (iRODS) is a popular open source policy-based data management system (application) that enables data sharing, publication and preservation and is also capable of implementing an automated data analysis pipeline. For each type of data management application, policies or rules can be applied that control the execution of procedures that enforce desired collection properties. By evolving the policies, a collection can migrate through the stages of the data life cycle.
DataDirect Networks - Storage Fusion Architecture is a highly scalable storage platform capable of hosting iRODS in a tightly coupled solution with a RAID controller and parallel file system providing an appliance like solution that can scale to multiple-petabytes in a single name space.

Tybee LIVE CAMS: Check July 4th holiday beach crowds and traffic
Jim Furyk defeated Kevin Kisner with a birdie on the second extra hole (No. 17), and Kisner dropped his first playoff on the Tour.
Furyk improved to 4-8 in playoffs in his career.
HILTON HEAD ISLAND, S.C. - Jim Furyk enjoys playing at Harbour Town Golf Links, and now, he enjoys it twice as much.
HILTON ISLAND, S.C. - One day after equaling the RBC Heritage tournament record with a 10-under-par 61, Troy Merrit carded a third-round 2-under-par 69 to maintain his lead heading into the final round.
HILTON HEAD ISLAND, S.C. - Troy Merritt built on his tournament record-tying second round, Matt Kuchar remained within reach of back-to-back titles and fan favorite Jordan Spieth kept himself in the mix Saturday in the third round of the RBC Heritage.
HILTON HEAD ISLAND, S.C. - Troy Merritt equaled the RBC Heritage tournament record with a 10-under 61 Friday, and moved clear of defending champion Matt Kuchar and John Merrick by four strokes.
HILTON HEAD ISLAND, S.C. - Troy Merritt seemingly came out of nowhere to snag sole possession of first place during the second round of the RBC Heritage Friday, shooting a 10-under-par 61 as the tournament heads into its final two days of play.
HILTON HEAD ISLAND, S.C. - Blake Adams admitted it "meant nothing," but he did it anyway.
He glanced at the leaderboard. Not necessarily where the former Georgia Southern standout was in relation to the RBC Heritage first-round leaders.
HILTON HEAD ISLAND, S.C. - Graeme McDowell shot a 5-under-par 66 in the opening round of the 2015 RBC Heritage, tying with two-time PGA Tour winner Matt Every for first place on Thursday.
HILTON HEAD ISLAND, S.C. - In his last four starts, Jordan Spieth has two wins - one of which was last week's Masters - and two runner-up finishes. At 21, the Texan is the youngest player to lead the FedExCup points standings.

Stetson has organized successful exhibits at all three of the Orlando MakerFaires. Here is another opportunity to be the cool kids.
On April 18, 2015 Gulf Coast MakerCon will be held at the Florida Fairgrounds (East of Tampa). Although the MakerCon is an hour further away than the Orlando event, it comes at a much better time of year, when you all should have some great projects to showcase. In fact it's a week after Stetson Showcase so you can double down on anything you prepare for that.
The event website with more details is at: http://gulfcoastmakers.com/gulf-coast-makercon/
They plan to host "80-100 makers, with expanded outdoor exhibits, a large scale *fighting robots *competition, a *ComicCon*, a *Young Makers Corner* and a *Steampunk Ball* after party for makers and guests." Apparently they are fond of asterisks as well.
If you would like to be part of a Stetson booth at this event, let me know at email@example.com. Don't worry about transportation or fees, just start thinking about what you might share with Gulf Coast makers.

Top 20 Flyers Prospects, #7
1. C Scott Laughton(77.36%)
2. D Samuel Morin(59.70%)
3. D Robert Hagg(69.74%)
4. D Shayne Gostisbehere(66.30%)
5. G Anthony Stolarz(48.15%)
6. C Nick Cousins(77.22%)
Straka. After that, you can pick the rest of them out of a hat because they are all deep long-shots to develop into anything that won't be easily replaceable.
I went Mcginn. He showed me enough last year that I'm not afraid to put him in the lineup if needed. He can get to the front of the net and clean up garbage pretty well. He's also very physical. His skating seemed to be the huge knock on him coming into last year, but wasn't near as bad as reported.
If it wasn't for the extreme severity of the concussions, I would have taken Bourdon. You could probably twist my arm into voting for Alt, Noebels, Leier or Lauridsen as well. I haven't seen enough of that crop (except Lauridsen) to really know.
Please add Matt Konan to the list for next time. The kid did enough to earn a call-up as a 21 year old rookie and didn't look bad when he dressed. He at least deserves to be on the list.
wow Akeson 0 votes
Went with Straka. I'd say he has a higher ceiling than McGinn but McGinn is closer to his potential at the moment, so it comes down to what you are basing the poll off of.
Was between Straka and McGinn for me. I think Straka has a chance for a higher ceiling than McGinn (which McGinn's isnt too high). Should be 1-2 them though for 7-8.
Straka. He seems to be a bit of a wildcard and may have more potential than a guy like McGinn.
Went Straka, next it's a toss up.
McGinn looks to be a solid 4th line, and might one day be a good 3rd liner. So that seemed pretty good.
Straka is a huge long shot to be at best a mediocre NHL player. There's a reason you don't see any prolific scorers with his kind of career trajectory.
McGinn at least has a skill set to play in the bottom 6.
It's nice to have a home grown bottom 6 guy, but you can find those players at any time. Even if Straka amounts to absolutely nothing (and that's very likely), I'd rather take a chance on a prospect like him than one like McGinn who is guaranteed to never be anything better than a bottom six presence.
Also, I disagree that Straka has a shot at being more valuable. I doubt he plays more than a handful of NHL games in his career (if any). Is Straka's offensive upside really much better than McGinn's anyway? I mean, McGinn scored at a better pace than Straka in junior. I'd rather have someone who drives the net frees up space for more talented players than someone who tries a stupid toe drag and turns the puck over 90% of the time.
Gonna go with Mcginn here. I loved this pick when we made it and had him pegged with quality 3rd line upside. I think he's on par for that and has shown potential, albeit little, to play compliment up higher using his assets properly. The kid has a great attitude, wears his heart on his sleeve, sticks up for teammates and has only exceeded expectations when given the opportunity. a nice Flyer.
I really haven't looked into Straka that deeply but hear he has the skills to score. I like to be optimistic about him but so far, as opposed to Mcginn, he's only failed to meet the expectations of others.
McGinn because he has done everything right so far and exceeded expectations.
Am I the only one struggling to get a read on players who haven't even played a single game for the organization yet?
Straka seems to have some skill from what I've heard but could as well be just another Stefan Legein who just doesn't have it in him...
How can everyone be so high on straka when no one has seen him play.
That being said, Straka's offensive potenial is absolutely higher than McGinn. Straka was hurt which killed two years for him. There is a reason why what, 15 NHL teams wanted him? Also a reason he wa a 2nd round pick. You can discredit his defense, but to say he has no offensive potenial, i think those who did watch him play would 100% disagree with you. A few even went into the prospect thread and talked about him.
But this poll shows the split in type of players people like. We got the rough and tough player and the dangle around people player. Looking at where people vote alot from both sides have shown which type of player they like in the past. Hell even norm said he likes the rough and tough over the dangle.
I went Straka based off of potenial. Will he hit it? No idea. McGinn type of players are really easy to find though so I choose potenial.
Once again, McGinn.
I gave some love to MA Bourdon, in the hope that he is recovering well from PCS and still can have an impact (and withstand impact) in the NHL.
went with Noebels, while McGinn is closer to NHL ready, he's also older, Noebels may have more upside
