Abstract: The present invention is a thermally activated electrical switch for use in simulating human activity. The invention is features dual heat sources enclosed in a thermally isolated chamber within the invention. Since the activation of the switch is dependent upon the ambient temperature of the environment, it opens and closes at sufficiently random intervals to simulate human activity. Other embodiments include the use of photoelectric sensors and timers to further vary timing of the switch actuation.

Abstract: The present invention is a component for an alarm system that may serve as an active component or an inactive, or decoy, component. The component is a small casing mountable in a visible manner that indicates activation with a flashing LED. Inside the component, the circuitry necessary to flash the LED and possibly monitoring devices, depending on the component's status as an active or inactive component. Active components also have security monitoring devices contained within the casing that monitor the surrounding environment through an access port. When a situation in the environment is registered by the device, it sends a signal to the alarm system of which it is a part. As added utility, the active and inactive components are outwardly indistinguishable, thus allowing the inactive components to serve as decoys either within a subscriber's alarm system or with non-subscriber's property, thus fulfilling a need for a high-tech version of the posted sign deterrent used in the alarm system industry today.

Abstract: A post including a back post and leg, together constituting a one-piece member. The member is bent to form the back post and leg, and when it is in upright active position, the back post rests against the wall, and the leg extends forwardly at an acute angle to the back post. A foot is secured to the lower end of the leg, extending transversely and engaging the floor. The back post is provided with holes for receiving brackets. There is no mechanical connection between the post and the wall or floor.

Abstract: A self-contained unit that is screwed into a lamp socket, and itself having a socket into which a light bulb is screwed. It includes an internal electronic unit, which functions in response to variation in capacitance, for turning on the bulb, and increasing its brilliance in steps, and turning it off. A sensor bracket includes a finger connected at one end with the electronic unit and extends outwardly from the unit and has a set screw turned in against the lamp socket in which the unit is mounted.

Abstract: An automatic tracking apparatus is provided for maintaining alignment of music rolls in player organs and player pianos using an improved, air pressure controlled, sensing and control device. More particularly this system incorporates an air pressure sensing device utilizing a piston/cam controlled pendulum to operate a pneumatic alignment device.
