Abstract: A removable interlock spacer is disposed between the rear face of a control knob and the face of a control panel of a cooking device, such as a stove or a barbecue grill, to prevent the control knob from being pushed in far enough to activate the associated cooking element(s). The push-in-and-turn type switches used in such devices require that the control knob be pushed in before the switch can be moved from its off position. The interlock spacer is of sufficient thickness to prevent the control knob from being pushed in far enough to allow the switch to be moved from its off position. Thus, the cooking element cannot be activated with the interlock spacer in position. When the cooking device is to be used, the interlock spacer may be removed and the switch will operate normally. Thereafter, when cooking is complete, the interlock spacer is re-installed so that young children and the like will not inadvertently create a hazard to themselves and others.

Abstract: A system is described for discriminating between a transmitted signal and background noise comprising a transmitter adapted to transmit a signal including first and second pulses, separated by a predetermined time interval; and a receiver including a pulse detector to detect pulses received from the transmitter; a delay circuit adapted to delay transmission of the first pulse for a predetermined period of time in communication with the detector to receive a pulse therefrom; and an AND gate having an output, a first input in communication with the delay circuit and an second input in communication with the detector, the time of transmission between the pulses equaling the time delay of the delay circuit, whereby the AND gate allows transmission of a signal only when simultaneously receiving pulses from the detector and the delay circuit.

Abstract: The present invention measures the energy consumption of battery-powered telephone devices to prevent the inadvertent deep discharge of a vehicle's battery by prolonged use of said devices when the vehicle is unattended. In a preferred embodiment, current to the devices is incrementally measured or estimated from a measurement of other relevant parameters. The incremental measurements of current are accumulated to produce a total current consumption indicative of the total energy consumption. At each update after an incremental measurement, the accumulated total is compared to a pre-established or adaptively determined. When the total energy consumption meets or exceeds the threshold, the power to the battery-powered telephone device is interrupted in order to conserve a sufficient amount of power to start the vehicle and to operate other peripheral systems.
