Body sensing switch and warning system

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.

1 . Body sensing switch and warning system comprising:
 a resilient cushion;
 a resilient over-cushion 
   a fabric cushion cover;   a rigid cushion bottom tray;   a right vertical structural arm;   a left vertical structural arm;   a horizontal structural support bar;   a left vertical housing;   a right vertical housing;   a light beam transmitter;   a light beam sensor sensor;
 an RF transmitter device 
 a printed circuit board and associated standard electronic components; 
 an electronics housing; 
   a portable power supply;
 a power supply input jack; 
 a wall pack transformer and attached power cord; 
   a digital audio recorder and playback circuit;   a speaker;
 a micro-processor for processing said transmitting, audio and infra-red signals; 
   a piezo beeper;
 a power on-off switch; 
   a receiver on off switch;   a receiver reset switch;
 an RF receiver circuit; 
 a micro-processor and standard electronics for processing said RF receiver signal 
   a power supply for said receiver circuit;   a power indicating LED for said receiver circuit; and   a portable receiver housing;
 said right structural arm perpendicularly attached to the said right end of said horizontal support bar and covered by said right vertical housing; 
 said left structural arm perpendicularly attached to the said left end of said horizontal support member and covered by said left vertical housing; 
 said light beam transmitter attached to the upper portion of said left structural arm so that it faces said light beam sensor; 
 said light beam sensor attached to the upper portion of said right structural arm so that it faces said light beam transmitter; 
 said horizontal structural bar residing under said cushion; 
 said horizontal structural bar residing on top of said cushion bottom tray; 
 said cushion residing on top of said horizontal structural bar; 
 said right and left structural arms rising above the level of the top of said cushion; 
 said RF transmitter circuit, said portable power supply, said printed circuit board and associated electronics all residing in said electronics housing located within a centrally located within a hollowed out portion of said cushion and fastened to said horizontal structural member; 
 said electronics housing covered by said over-cushion; 
 said power on-off switch and said power supply jack fastened to one said vertical support arm; 
 said speaker attached to one said vertical support arm; 
 said fabric cushion cover surrounding said cushion and said over-cushion; 
 said RF receiving electronics, said piezo beeper, said on-off switch, said receiver reset switch and power supply residing in said portable receiver housing; 
 so that when a person sits on said cushion and the present invention is turned on by said power switch, a beam created by said light beam transmitter is broken by the body of said person thereby telling said light beam sensor and associated said micro-processor that a person is sitting on said cushion; 
 and when said person gets up from said cushion, said light beam is unbroken, telling the said micro-processor that the user is no longer sitting on said cushion at which time said RF transmitter sends a signal to said RF receiver which is being carried remotely by a care giver and said peizo beeper within said RF receiver housing is activated thereby signaling the said care giver that said person has gotten up from said cushion; 
 said care giver can then turn off said beeper by pressing said reset switch located on said receiver housing; 
 and a pre-recorded digital message stored in said audio circuit is sent to said speaker audibly asking said person who has just gotten up from said cushion to sit back down.
