FIELD OF THE INVENTION  
         [0001]    This invention relates to the field of temperature sensing apparatuses, specifically those specially adapted for use on an infant.  
         BACKGROUND OF THE INVENTION  
         [0002]    The health of one&#39;s children has always been considered to be of the utmost importance. This is especially true of newborns and infants who, having built up few immunities to sickness and disease, are very vulnerable. Furthermore, serious disease or maladies early in life may lead to permanent physiological problems in the child&#39;s future. Therefore, many parents spend a great amount of time checking on their infants so that they may either prevent sickness from occurring or help eliminate it as soon as it does occur.  
           [0003]    One very important key to an infant&#39;s health is maintaining an infant&#39;s body temperature within a certain tolerance level of the average human body temperature. A high body temperature beyond a certain tolerance level may be undesirable. The third leading cause of death among infants 1 month to 1 year in age is Sudden Infant Death Syndrome (SIDS), the unexpected death of an infant typically under 1 year old, without explicable cause. While SIDS has no symptoms and provides no indication, parents can follow some precautionary measures to help minimize the possibility that their child may afflicted. One precautionary measure now being advocated by doctors is preventing a sleeping infant&#39;s body temperature from rising too highly and/or too rapidly.  
           [0004]    A high body temperature is undesirable for other reasons as well. For example, a high body temperature may cause a small infant discomfort, leading him to cry and scream. A high body temperature may also be the sign of an infectious disease which should be attended to by the parent. An extremely high body temperature at an early age may even cause permanent brain damage or death.  
           [0005]    An abnormally low body temperature is equally undesirable. Because an infant contains less body fat than an adult, certain ambient temperatures that may be comfortable for an adult may be too cold for an infant. This would leave the infant uncomfortable which may lead to the infant crying and screaming. Furthermore, a low body temperature may also be indicative of a malady or sickness.  
           [0006]    It would be desirable, then, to have a device that periodically monitors an infant&#39;s body temperature automatically so that a parent may take appropriate measures if the infant&#39;s body temperature is too high or too low.  
         SUMMARY OF THE INVENTION  
         [0007]    The present invention is a system for continuously monitoring the body temperature of an infant in order to promote health and comfort.  
           [0008]    According to one aspect of the invention, the monitoring system includes a temperature monitoring station having a housing, a temperature sensor and a Radio Frequency (RF) transceiver and a companion station having a housing, an RF transceiver and an output device.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0029]    The present invention is a system for continuously monitoring the body temperature of an infant in order to promote health and comfort.  
         [0030]    [0030]FIG. 1 illustrates one embodiment of the present invention. The present invention may include a temperature monitoring station (TMS)  10  and a companion station (CS)  5 . It may also include a single TMS  10  and more than one CS  5 , or, conversely, it may include more than one TMS  10  and a single CS  5 . Lastly, it may include more than one TMS  10  and more than one CS  5 . The TMS  10  monitors the infant&#39;s current body temperature. It may transmit and receive information to and from the CS  5  through radio frequencies (RF). As such, a user may remotely control one of these devices by interacting with the other.  
         [0031]    [0031]FIG. 2 illustrates the TMS  10  embodied as an adhesive patch. The adhesive patch may be composed of two layers pressed together to form a single unit.  
         [0032]    [0032]FIG. 2 a  illustrates the topside view of the top layer of the TMS  10 . The topside of the top layer of the TMS  10  may contain various elements. For example, it may contain a graphic  20 . This graphic  20  may be the logo of the manufacturer, as illustrated, or it may be some other graphic. One popular alternative may be a graphic that is often associated with small infants, such as clowns or teddy bears. Another popular graphic may be a cartoon character.  
         [0033]    The topside of the top layer may also contain an actuation button  40  in the micro-circuitry area  30 . A user may press the actuation button  40  to turn the temperature monitoring system on or off. The actuation button  40  may also be many buttons, each button having a respective function. For example, one button may turn the entire system on and off, while another button may turn a local display  50  on or off.  
         [0034]    The topside of the top layer may also contain a local display  50  in the micro-circuitry area  30 . The display  50  may be a digital display for displaying the infant&#39;s current body temperature. The digital display may display the body temperature in Fahrenheit or Celsius or both. The type(s) of temperature scale displayed may be predetermined by the designer, or it may be selected by the user. The display  50  may also be a color display so that different colors may be used to represent a range of body temperatures. For example, when the infant&#39;s body temperature is 98-99 Fahrenheit, the display  50  may display a green background. If the infant&#39;s body temperature is 99-100 Fahrenheit, the display  50  may display a yellow background. If the infant&#39;s body temperature is over 100 degrees Fahrenheit, it may display a red background. The ranges associated with a specific color may be predetermined by the designer, or they may be set by the user. The display  50  may also be a combination of a color display and digital display. For example, if the infant&#39;s body temperature was 98.6 degrees Fahrenheit, a digital “98.6 F.” could appear on a colored background (e.g. green background).  
         [0035]    [0035]FIG. 2 b  is an underside view of the bottom layer of the TMS  10 . A portion of the underside layer of the TMS  10  may be adhesive so that when the TMS  10  is pressed upon a child&#39;s skin, the TMS  10  will stick to the skin and will not accidentally slip off. The adhesive material  60  may be spread liberally on the underside of the patch, or it may be placed on the underside of the patch in small, evenly spaced amounts as illustrated in FIG. 2 b.  The adhesive material  60  should be such that when removing the TMS  10  from the child&#39;s skin, the child&#39;s skin is not hurt.  
         [0036]    The underside of the bottom layer of the TMS  10  may also contain a temperature sensor  70 . The temperature sensor  70  may be a conventional electrical thermometer plate for measuring surface temperature, which is apparent to those skilled in the art. When the patch is placed on the infant&#39;s skin, the temperature sensor  70  may press against the infant&#39;s skin.  
         [0037]    [0037]FIG. 2 c  illustrates a side view of the present invention embodied as an adhesive patch. As noted earlier, the TMS  10  is composed of a top layer  90  and a bottom layer  100 . The two layers may be pressed together so as to form a single distinct unit. As also noted earlier, the TMS  10  has a micro-circuitry area  30  where the micro-circuitry resides between the top layer  90  and the bottom layer  100 . The micro-circuitry area  30  may be rectangular in shape, as illustrated by guidelines  80  in FIG. 2 c,  or it may be in another shape.  
         [0038]    [0038]FIG. 3 illustrates the micro-circuitry of the TMS  10 . As noted earlier, the micro-circuitry may reside in the micro-circuitry area  30  of the TMS  10  and it may include an actuation button  40 , a display  50 , and a temperature sensor  70 . The micro-circuitry may also include a micro-controller  110  and an RF transceiver  120 . The RF transceiver  120  may include an antenna. The micro-circuitry may also include a battery (not shown). A typical operation will now be described.  
         [0039]    The TMS  10  may be placed in the appropriation location prior to system activation. For example, it may be attached to the child&#39;s skin prior to activation. Users desiring to activate the temperature monitoring system may do so in different ways. For example, a user may press the actuation button  40  on the TMS  10 . This may generate an interrupt signal at the micro-controller  110 . Users may also activate the monitoring system at the CS  5 . The CS  5  will generate an interrupt signal that is transmitted to the TMS  10  through RF. The interrupt signal may be received at the RF Transceiver  120  and passed to the micro-controller  110 .  
         [0040]    While the system is not active, the micro-controller  110  may reside in a typical “Sleep” Mode so as to conserve battery power. Upon receiving an activation interrupt signal, the micro-controller may “Wake.” If the interrupt was received at the actuation button  40 , the micro-controller  110  may activate the RF Transceiver  120  and send a corresponding activation signal to the CS  5  indicating that the system is now active.  
         [0041]    After the activation of the TMS  10  and the CS  5 , the micro-controller  110  may poll a respective input line for a configuration signal if the system is configurable by the user. Since the actuation button  40  may be more than one button, a configuration signal may be generated by pressing one of the actuation buttons  40 . A configuration signal may also be generated at the CS  5 , transmitted to the RF transceiver  120  and passed to the micro-controller  110 . If a configuration signal is detected, the micro-controller  110  may prompt the user for the desired configuration on the local display  50 . A user may enter configuration information using the actuation button  40 . Configuration information may be stored in the memory buffer of the micro-controller  110 . The information may also be sent to the CS  5  and stored in the memory buffers of the micro-controller  550 .  
         [0042]    If a configuration signal is not received within a time-interval pre-determined by the designer, the micro-controller  110  times out and prevents the user from configuring the system. The micro-controller  1   10  may then send a signal to the temperature sensor  70  to monitor the infant&#39;s current body temperature.  
         [0043]    The temperature sensor  70  may be capable of sensing the infant&#39;s body heat, and converting that signal to a body temperature. The body temperature information may then be sent to the micro-controller  110 . Alternatively, the temperature sensor  70  may only be capable of sensing the infant&#39;s body heat. If so, the body heat information may be sent to the micro-controller  110  which may then convert the body heat information to body temperature information. The micro-controller  110  may store the body temperature information in its memory buffers. It may also display body information on a local display  50 .  
         [0044]    The micro-controller  110  may be configured so that so long as the system remains activated, the micro-controller  110  activates the temperature sensor  70  periodically. For example, it may active the temperature sensor  70  and obtain a new data reading every  6  seconds. The periodic time interval may be pre-determined by the designer, or it may be configured by the user. While a shorter time interval between readings provides more accurate information, a longer time period helps extend battery life.  
         [0045]    The micro-controller  110  may also transmit information to the CS  5  through the RF Transmitter  120 . The information sent to the CS  5  may be body heat information or it may be actual body temperature information. The micro-controller may also send a simple alarm signal to the CS  5  if appropriate. For example, the micro-controller  110  may compare the infant&#39;s current body temperature stored in its memory buffer to a predetermined number (e.g. average body temperature). If the infant&#39;s body temperature is above or below a certain tolerance level of that pre-determined number (e.g.,  1  degree), the micro-controller  110  may send an alarm signal to the RF transceiver  120 , which may transmit the signal to the CS  5 .  
         [0046]    The micro-controller may also send an alarm signal to the CS  5  only when a series of body temperature readings are not within a certain tolerance level of a pre-determined number. For example, the micro-controller  110  may determine that a body temperature reading is above or below a tolerance level for a pre-determined number. Rather than sending a signal immediately, the micro-controller  110  may wait for a second temperature reading. If a second temperature reading is above or below a certain tolerance level for a pre-determined number, the micro-controller  110  may send an alarm signal to the CS  5  through the RF Transceiver  120 , or it may wait for a third temperature reading. The number of continuous temperature readings which must be above or below a certain tolerance level of a pre-determined number may be configured by the designer, or it may be configured by the user. By sending a signal only when a series of temperature readings indicates an anomalous body temperature, the user may reduce the occurrence of false alarms. For example, an infant&#39;s body temperature may rise below a certain tolerance level for one reading because of some physical exertion by the infant. As such, it may not be advantageous to transmit an alarm signal for every temperature reading that is anomalous. It may be noted, however, that the greater the number of temperature readings compared, the longer a valid alarm signal might be delayed.  
         [0047]    The temperature sensor  70  may continue to monitor the infant&#39;s body temperature in pre-determined intervals until the micro-controller  110  sends a “Stop” signal. Such a “Stop” signal may occur when a second interrupt signal is received at the micro-controller  110 . Such an interrupt signal may occur when the user presses the actuation button  40  for a second time, or when a second remote interrupt signal is received at the RF Transceiver  120  and passed to the micro-controller  110 . After the micro-controller  110  has processed a “Stop” signal, it may return to “Sleep” mode to conserve power.  
         [0048]    The TMS  10  may be physically embodied in various different forms other than an adhesive patch.  
         [0049]    [0049]FIGS. 4 a  and  4   b  illustrate the TMS  10  embodied as a strap. The strap may have many of the same elements as in FIG. 2, such as a graphic  20 , an actuation button  40 , and a local display  50 . The micro-circuitry may also reside in the micro-circuitry area  30 . The underside of the strap may also have a temperature sensor  70 .  
         [0050]    Instead of attaching the patch to the infant with adhesive  60 , the TMS  10  may be strapped on to the child using a buckle  210  and buckle holes  200 . The strap may be locked around the child&#39;s arm, leg, or neck so that the temperature sensor  70  presses against the child&#39;s skin. The buckle  210  may be inserted into the buckle holes  200  to prevent the TMS  10  from slipping off. The buckle holes  200  may be pre-punched by the designer, or they may be punched by the user so that the strap is a custom-tailored fit for their infant.  
         [0051]    The buckle  210  and the buckle holes  200  may also be replaced by Velcro hook and loop patches. Again, the strap may be locked around a certain part of the child so that the temperature sensor  70  presses against the skin. The Velcro hook patch may be pressed against the Velcro loop patch, thereby creating a snug fit.  
         [0052]    [0052]FIG. 5 illustrates the TMS  10  embodied as a pacifier. The pacifier may have an actuation button  40 , a local display  50 , and a micro-circuitry area  30  for the micro-circuitry to reside. The micro-circuitry area  30  may be in the plastic base of the pacifier. The TMS  10  may also have a handle  310  similar to the handles found on typical pacifiers.  
         [0053]    The temperature sensor  70  may be placed on the rubber nipple  300  which is placed in the infant&#39;s mouth. When the system is activated, the temperature sensor  70  may determine the infant&#39;s body temperature. Also, the rubber nipple  300  may be constructed of the same type of material as the temperature sensor  70  so that the two may be interwoven so as to comprise a single unit.  
         [0054]    [0054]FIG. 6 schematically illustrates the TMS  10  as a stocking cap. FIG. 6 a  schematically illustrates the outer surface of the stocking cap. The stocking cap may be have a brim  350  and a stocking  400 . The stocking cap may also have an actuation button  40 , a local display  50 , and a micro-circuitry area  30 . The micro-circuitry may be sewn into the brim  350  of the hat in a specific area  30 .  
         [0055]    The stocking  400  for the stocking cap may be manufactured from many different materials. For example, if the parent desires to keep their infant cool, the stocking  400  may be manufactured from lightweight linen or terrycloth. If the parent desires to keep their infant warm, the stocking  400  may be manufactured from cotton or wool. Those skilled in the art will note that the stocking may also be manufactured from some combination of commonly known fabrics.  
         [0056]    [0056]FIG. 6 b  illustrates the insides of the stocking cap&#39;s brim  350 . The insides of the brim  350  may have a temperature sensor  70  sewn into the micro-circuitry area  30 . When the stocking cap is placed on the infant&#39;s head, the brim  350  may fit snugly around the infant&#39;s head so that the temperature sensor  70  is pressed against the infant&#39;s skin (e.g. the infant&#39;s forehead).  
         [0057]    [0057]FIG. 7 illustrates the TMS  10  as a finger clasp  450 . The finger clasp  450  may be manufactured from rubber, plastic, or some other appropriate material. The finger clasp  450  may include an actuation button  40 , a local display  50 , and a micro-circuitry area  30  located at the base of the clasp. The inner surface of the finger clasp  450  may have a temperature sensor  70 . When the finger clasp is slipped over an infant&#39;s finger, the temperature sensor  70  may press against the infant&#39;s skin so that the infant&#39; body temperature may be monitored.  
         [0058]    [0058]FIG. 8 illustrates the TMS  10  as an infrared heat detector. The TMS  10  may be placed on a crib  460  so that the TMS  10  is pointed at the infant&#39;s body  470 . As in the other embodiments, the TMS  10  may include an actuation button, a local display, micro-circuitry, and a micro-circuitry area (not shown). The temperature sensor  70  may be an infrared detector, which when pointed at the infant&#39;s body, may detect the infant&#39;s body heat. The body heat information may be passed to the micro-controller  110 , which may convert the body heat readings into body temperatures.  
         [0059]    [0059]FIG. 9 illustrates the system&#39;s companion station (CS)  5  as a console. The CS  5  may contain a local display  500 , although it does not have to. The display  500  may be a digital display for displaying the infant&#39;s current body temperature. The digital display may display the body temperature in Fahrenheit or Celsius or both. The type(s) of temperature scale displayed may be predetermined by the designer, or it may be selected by the user. The display  500  may also be a color display so that different colors may be used to represent a range of body temperatures. For example, when the infant&#39;s body temperature is 98-99 Fahrenheit, the display  500  may display a green background. If the infant&#39;s body temperature is 99-100 Fahrenheit, the display  500  may display a yellow background. If the infant&#39;s body temperature is over 100 degrees Fahrenheit, it may display a red background. The ranges associated with a specific color may be predetermined by the designer, or they may be set by the user. The display  500  may also be a combination of a color display and digital display. For example, if the infant&#39;s body temperature was 98.6 degrees Fahrenheit, a digital “98.6 F.” could appear on a colored background (e.g. green background).  
         [0060]    The CS  5  may also include a graph display  510 . The graph display  510  may display the infant&#39;s average body temperature over a specific time interval. The time interval may be predetermined by the designer, or it may be configured by the user. The graph display  510  may display information as an analog graph or it may display information as a digital graph.  
         [0061]    The CS  5  may also include a keypad  520  for inputting information. The keypad  520  may be a single key, or it may be more than one key. The local display  520  may display information  520  based on input entered at the keypad  520 .  
         [0062]    The CS  5  may also include a speaker  530  for making alarm signals audible. The CS  5  may also include an antenna  540  connected to its RF Transceiver (not shown). The CS  5  may also include a micro-controller (not shown).  
         [0063]    [0063]FIG. 10 illustrates the micro-circuitry of the CS  5 . As noted, the micro-circuitry of the CS  5  may include a local display  500 , a graph display  510 , a keypad  520 , and a speaker  530 . The micro-circuitry may further include a micro-controller  550  and an RF Transceiver  560  connected to an antenna. The micro-circuitry may also include a battery (not shown), or it may be powered by some other power source (e.g. AC wall outlet). A typical operation will now be described.  
         [0064]    The TMS  10  may be placed in the appropriate location prior to system activation. For example, it may be attached to the child&#39;s skin prior to activation. Users desiring to activate the temperature monitoring system may do so in different ways. For example, a user may press the keypad  520  on the CS  5 . This may generate an interrupt signal at the micro-controller  550 . Users may also activate the monitoring system at the TMS  10  (see above). The TMS  10  will generate an interrupt signal that is transmitted to the CS  5  through RF. The interrupt signal may be received at the RF Transceiver  560  and passed to the micro-controller  550 .  
         [0065]    While the system is not active, the micro-controller  550  may reside in a typical “Sleep” Mode so as to conserve battery power. Upon receiving an activation interrupt signal, the micro-controller may “Wake.” If the interrupt was received at the keypad  520 , the micro-controller  550  may activate the RF Transceiver  560  and send a corresponding activation signal to the TMS  10  indicating that the system is now active.  
         [0066]    After the activation of the TMS  10  and the CS  5 , the micro-controller  550  may poll a respective input line for a configuration signal if the system is configurable by the user. Since the keypad  520  may be more than one key, a configuration signal may be generated by pressing on the keypad  520 . A configuration signal may also be generated at the TMS  10 , transmitted to the RF transceiver  560  and passed to the micro-controller  550 . If a configuration signal is detected, the micro-controller  550  may prompt the user for the desired configuration on the local display  500 . Users may enter configuration information using the keypad  520 . The configuration information may be stored in the memory buffer of the micro-controller  550 . It may also be transmitted to the TMS  10  and stored in the memory buffers of micro-controller  110 .  
         [0067]    If a configuration signal is not received within a time-interval pre-determined by the designer, the micro-controller  550  times out and prevents the user from configuring the system.  
         [0068]    Information may be received by the CS  5  at the RF Transceiver  560 . For example, the CS  5  may receive body temperature information at the RF Transceiver  560 . This body temperature information may be passed to the micro-controller  550 . The micro-controller  550  may store the information in its memory buffer. It may display the information on the local display  500 . It may use a series of body temperature readings to create a graph for display on the graph display  510 . If the body temperature reading is above or below a certain tolerance level of pre-determined number (e.g. average body temperature), it may generate a signal at the speaker  530  causing an alarm to sound.  
         [0069]    The CS  5  may also receive body heat information at the RF Transceiver  560 . The information may be passed to the micro-controller  550  which may convert the body heat information to body temperature data. The micro-controller  550  may store the body temperature information in its memory buffer. It may display the body temperature information on the local display  500 . It may use a series of body temperature readings to create a graph for display on the graph display  510 . If the body temperature reading is above or below a certain tolerance level of pre-determined number (e.g. average body temperature), it may generate a signal at the speaker  530  causing an alarm to sound.  
         [0070]    The CS  5  may also receive a simple alarm signal at the RF Transceiver  560 . If such a signal is received, the micro-controller  110  at the TMS  10  has already determined that the body temperature reading or series of body temperature readings is above or below a certain tolerance level of a pre-determined number. Such an alarm signal would be passed to the micro-controller  550 . The micro-controller may generate a signal at the speaker  530  so that an alarm may sound.  
         [0071]    The CS  5  may be physically embodied in many different forms.  
         [0072]    [0072]FIG. 11 illustrates the CS  5  embodied as a wearable wrist device. The CS  5  may be strapped to the wrist of a user&#39;s arm  610 . The CS  5  may include a local display  500 , a keypad  520 , and a speaker  530 . It may also include a micro-controller  550  and an RF Transceiver  560  (not shown). The microprocessor  550  may be configured so that when the system is not activated, the local display  500  functions as a chronometer.  
         [0073]    [0073]FIG. 12 illustrates the CS  5  embodied as a miniature console in the form of a pager or beeper. The CS  5  may be attached to the user&#39;s clothing by a clip  620 . The CS  5  may include a local display  500 , a keypad  520 , and a speaker  530 . It may also include a micro-controller  550  and an RF Transceiver  560  (not shown). The microprocessor  550  may be configured so that when the system is not activated, the local display  500  functions as a chronometer. The CS  5  may be further configured to work as a regular pager when the system is not activated.  
         [0074]    [0074]FIG. 13 illustrates a system where multiple CS  5  are utilized. Because of recent studies indicating the possible dangers of cellular phone use, parents may be hesitant to place a device with an RF Transceiver on their infant child. It would be advantageous, then, to have a system where the RF Transceiver  120  in the TMS  10  is relatively low-powered.  
         [0075]    Such a system may be realized by using two (or more) CS  5 . CS  5   a  may be placed on or near a crib  460 . The TMS  10  may be placed on or near the infant  470 . When it is appropriate for the RF Transceiver  120  on the TMS  10  to transmit information, the TMS  10  may communicate with the CS  5   a  using a very low power signal. The signal may also be low in frequency. The signal may be received by the CS  5   a  and re-broadcast to CS  5   b.  The re-broadcast signal may be stronger in strength and power. As such, a system where a CS  5   b  is relatively far-away from the infant  470  may be realized without having the RF Transceiver  120  on the TMS  10  transmit a strong signal.  
         [0076]    Furthermore, if the CS  5   b  needs to transmit information to the TMS  10 , it may do so through the CS  5   a.  The CS  5   b  may send a strong signal to the CS  5   a.  The CS  5   a  may reduce the signal in intensity and relay it to the TMS  10  so that the TMS  10  receives a relatively weak RF transmission.  
         [0077]    Those skilled in the art will notice that if CS  5   a  is being used solely as a relaying station, it may simply include an RF transceiver and appropriate circuitry. However, it may also include other components such as a display  500   a,  a keypad  520   a,  etc. Similarly, CS  5   b  may include other components, such as display  500   b,  a keypad  520   b,  etc.  
         [0078]    [0078]FIG. 14 illustrates a system where a CS  5  has an attached mechanical arm  710 . The system may work as previously described. However, the CS  5  may be configured so that when a body temperature reading indicates a body temperature above or below a certain tolerance level of a predetermined number, the mechanical arm  710  either removes a blanket  700  from the infant&#39;s body or place&#39;s a blanket  700  on the infant&#39;s body. Although FIG. 14 only illustrates a single CS  5 , those skilled in the art will note that multiple CS  5  may be used as in FIG. 13.  
         [0079]    [0079]FIG. 15 illustrates a system wherein a heating pad  720  has been added. The heating pad  720  has a built-in RF Transceiver (not shown). When a body temperature reading indicates that the infant&#39;s body temperature is below a certain tolerance level of a predetermined number, either the TMS  10  or the CS  5  may transmit a signal the heating pad  720 . Such a signal would instruct the heating pad&#39;s heating element to activate so that the child would be provided warmth and comfort.
