Abstract
Body sensing switch and warning system with a resilient cushion and right and left vertical supports rising above the top of the cushion on either side of the cushion. An inwardly facing light beam transmitter is located on the top portion of one vertical support and an inwardly facing light beam sensor is located on the top portion of the other vertical support. When a person sits on the cushion, the light beam is broken, telling a microprocessor that a person is sitting on the cushion. When the person gets up from the cushion, the light beam is unbroken, thereby triggering a pre-recorded message telling the person to sit down. Also an alert is transmitted to a remote receiver carried by a care giver, telling the care giver that the person has gotten up from the chair.

- This invention relates generally to the field of Alzheimer patient care devices and more specifically to a body sensing switch and warning system.
- The prior art includes the following patents:
- Silver U.S. Pat. No. 2,359,254, Gault U.S. Pat. No. 4,242,672, Hamilton U.S. Pat. No. 4,538,142, Tingley U.S. Pat. No. 6,255,956, All the prior art patents require the use of a switch that is either mechanically activated or air activated. Both of these methods provide certain deficiencies. If a person does not sit squarely on a seat, a mechanical switch may not activate. If a switch is an air sensor type, any leak in the cushion or tubing leading to the cushion can cause the unit to fail.
- There is therefore, a need for a more reliable method of switch activation for a seat cushion designed to alert a care giver when a person has gotten up from his or her seat.
- The primary object of the invention is to provide a body sensing cushion system that detects whether on not a person is seated on a cushion.
- Another object of the invention is to provide a body sensing cushion system that sends a signal to a care giver when a person gets up from the body sensing cushion.
- Another object of the invention is to provide a body sensing cushion system that automatically plays a pre-recorded message when a person gets up from the body sensing cushion.

FIG. 1 we see a perspective view of aperson 2 sitting on the body detectingseat cushion 100 of the present invention which is in turn placed on astandard chair 4. Raisedhousings 6, 8 shown inFIG. 2 contain an an infra-red transmitter and receiver. The infra-red beam 12 is broken when aperson 2 is sitting on the cushion and unbroken when theperson 2 gets up from thechair 4. An infra-red light source was chosen in the preferred embodiment because if another light source was used that is in the visible spectrum, the beam receiving device may be triggered accidentally when an ambient light of a similar frequency strikes the beam receiver. However, it should be noted that other types of light beams may be used. Electronics, including a microprocessor and other standard components, within ahousing 24 shown inFIG. 3 process the information regarding the status of the infra-red beam and do two things. First, aprerecorded audio message 26B stored within thehousing 24 plays and tells theperson 2 to sit back down in the chair. Second, anRF transmitter 26A also located withinhousing 24 sends a signal to anRF receiver 91 located in aportable housing 90 as shown inFIG. 9 . Apiezo beeper 93 located in thehousing 90 alerts a care giver who is wearing thehousing 90 that theperson 2 has gotten up from his or her chair. -

Thestructural bar 16 terminates at each end invertical support arms red transmitter 42 is located on onevertical support arm 18 and a, infra-red receiver 44 is located on the othervertical support arm 20. The infra-red transmitter sends out abeam 12 that is located approximately four inches above the height of the top of theseat cushion cover 52. Eachvertical support arm support arm cover 8, 6. Support cover 8 has anaperture 46 that allowsbeam 12 to exit the housing 8.Support cover 6 has anaperture 48 that allows thebeam 12 to enter thehousing 6 and strike thereceiver 44. The electronics described above are located inhousing 24. The housing also encloses abattery power supply 28. The user can choose to power thedevice 100 by a wall pack transformer, not shown, that can by plugged intoinput jack 34. The user turns on thepower 28 by pressing on-off switch 36. When the power is on anLED indicator 38 becomes illuminated letting the care giver know that the unit is on. When a person gets up from thedevice 100, the infra-red beam 12 becomes unbroken. This action causes aprerecorded message 26B to be broadcast from speaker 32. The sound passes throughapertures 50 located in the side wall of support cover 8.Resilient foam cushion 22 includes a hollow area that allowselectronic housing 24 to centrally reside. Agel type cushion 40 is located just abovehousing 24 so that a person sitting on thecushion cover 52 will not feel the hardness of the top of thehousing 24. -
FIG. 4 shows a perspective view of thebase tray 14 withhorizontal support bar 16 fixed in place andelectronic housing 24 fixed in place centrally on top ofsupport bar 16. infra-red transmitter 42 andreceiver 44 can be clearly seen, as can speaker 32. -

FIG. 8 shows a top view of theinvention 100 -
FIG. 9 shows a perspective view of thereceiver housing 90. A belt clip 98 helps hold thehousing 90 onto a care giver's belt. The receiving unit is turned on by on offswitch 96. When aperson 2 gets up from the body detectingseat cushion 100 an LED 94 flashes and apiezo beeper 93 located within thehousing 90 sounds a warning to the care giver that theperson 2 has gotten up from his or her chair. After the care giver hears the alarm generated bybeeper 93, he or she can turn off the alarm by pressing thereset button 92. -
FIG. 10 shows a block diagram of the invention. Infra-red transmitter 42 emitsbeam 12 which is received bydetector 44. The condition of thebeam 12, either broken or unbroken is sent by electrical wires to the electronics that process thebeam condition 26. Theseelectronics 26, located withinhousing 24, include a standard microprocessor and other standard electronics mounted on a printed circuit board as well as a portable power supply. When thebeam 12 becomes unbroken thealert transmitter 26A sends a signal to thealert receiver 91 andpiezo beeper 93 located inremote housing 90. Thepiezo beeper 93 tells the caregiver wearing housing 24 that the person who was sitting on theseat cushion surface 52 has gotten up. Simultaneously, a digitalrecordable message 26B, also located withinhousing 24 sends a signal by wire to speaker 32 which talks to the person who has just gotten up from the chair and asks him or her to please sit back down. - Obviously, the
present invention 100 can be used for other purposes other than keeping track of Alzheimer patients, such as when a child needs to take a time out and is told to sit on theinvention 100 so that a parent or other care giver can go on with their activity and still know that the child is sitting on theinvention 100. - While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
