Abstract: Supervised wireless leak detection system, having a leak detection sensor unit, capable of transmitting a uniquely coded signal in response to a detected leak, a supervised wireless valve control transceiver unit having a receiver, capable of receiving said uniquely coded signal, and a transmitter for feeding the uniquely coded signal within the system, a valve shut-off mechanism in communication with said valve control transceiver unit said valve shut-off mechanism having a motor attached to a valve, said motor creating a rotation pulse used to close and open said valve, and a processor having an electronic circuitry containing sensor(s), detecting said motor rotation pulse count during a motorized valve closure or open process. Said processor functions in a setup process to memorize (learn) said motor rotation pulse count, required, to close and or to open the valve.

Abstract: A method utilizing a wireless leak detection and prevention system, used for preventing property damage and personal injury caused by liquid or gas leak. The system comprised of a wireless, battery operated apparatus having sensor(s) incorporated with an RF transmitter, used for detecting liquid or gas leaks, and transmits signal(s) to a wireless valve shutoff control unit. The valve shutoff control unit containing an RF transceiver and a processor designed to receive the detected signals and activate a supervised solenoid or motorized valve shut-off mechanism to stop the detected leak. In a preferred embodiment of the invention, the wireless valve control unit is connected to a motor, which is mounted on manual shutoff valve. Wherein the valve control unit activates the motor to produce torque to turn the valve towards a close position in response to a received detected leak signal from a sensor. An electronic or electromechanical circuitry is provided, to detect motor or gear turn cycles.

Abstract: Safety door system comprises of door edge and doorframe mount conductive material, which is connected to an electronic control circuitry equipped with an audio or visual warning alarm devise. The system is designed during door closure to detect human body limb (Fingers, hands) touching the door edge or door inner frame, and alert the person tempting to close the door, to the presence of human body limb between the door and doorframe, by an audio or visual alarm signal. During a door closure, if a human body limb touches the door edge or door inner frame mount conductive material. The electronic control circuitry detects the presence of human body touch, and transmits an audio or visual warning alarm, to avoid the users or other person(s) hand or finger(s) getting caught in between door and doorframe. In a preferred embodiment, the safety door system additionally is equipped with an electromechanical doorstopper, which is connected to an electronic control circuitry.

Abstract: An improved vehicle security system is disclosed in which different modes of arming and disarming the system are utilized. The system uses an arming feature to disable operation of the vehicle which is initiated by the vehicle ignition switch being turned off following which one or more doors of the vehicle are opened. The system also uses a voice actuated alarm deactivation procedure in which operation of the vehicle is enabled following voice identification of a spoken password as belonging to an authorized individual. The vehicle security system uses a positive interlock in which both the vehicle's starting system and its ignition system are disabled when the system is armed.

Abstract: A motion sensor for use with a security system provides an output signal to initiate an alarm whenever a significant level of movement is detected by the motion sensor. A light emitter directs light through an optical path onto a light detector, which generates an electrical output signal in response to the light directed onto it. A resiliently supported mass is coupled to the optical path to modify the optical path in response to motion imposed upon the mass, thereby reducing the transmission of light in the optical path and affecting the electrical signal as the mass moves. The motion sensor of the present invention is responsive to movement in all directions, and, since it is optical in nature, is immune to the presence of magnetic fields.

Abstract: An alarm or indicating system for indicating that an automotive appliance has been left in the vehicle. The system includes a circuit powered by the battery of the vehicle and a first switch which is closed by inserting the appliance into a predetermined position in the vehicle and opened by removing the appliance from the predetermined position. The circuit further includes a control switch that is operated by the door of the vehicle such that when the door is opened the control switch will be closed to energize the circuit of the appliance is in its predetermined position. When the operator removes the appliance it will open the first switch to de-energize the circuit and the alarm. When the door of the vehicle is closed the control switch will be opened and the alarm circuit will be de-energized.

Abstract: A system for use in an automobile to indicate that the user has failed to remove an appliance, such as a radio, when the ignition switch is turned off. The system includes a circuit including an audible or visual alarm, the automobile battery for powering the circuit, a relay connected between the battery and the alarm, the automobile ignition switch for controlling the relay, and a switch controlled by insertion or removal of the appliance from its compartment located, for example, in the dashboard of the automobile. When the appliance is inserted in its compartment with the ignition switch off, the alarm will be energized until the ignition switch is turned on. If the ignition switch is subsequently turned off while the appliance is still in its compartment, the alarm will again be energized, thus indicating that the appliance should be removed before leaving the automobile. Removal of the appliance will terminate the signal.
