    摘要: A sensor is provided for changing an operational characteristic of a circuit within a housing structure of the sensor to a preselected stimulus. The circuit within the housing structure is provided with magnetically sensitive components to change an operational parameter thereof. An object is provided to change the status of the magnetically sensitive component. The present invention incorporates a Hall effect element within the housing structure that is placed proximate a permanent magnet. Between the magnet and the Hall effect element a depression is formed to permit the insertion of a magnetically permeable object to change the magnetic field. The change in the magnetic field creates a change in the status of the Hall effect element and permits the circuit to change its operational characteristic.

    摘要: A packaging system for electronic circuitry is provided. The electronic circuitry may be disposed upon a substrate, which can be encased or otherwise surrounded by one or more components of the packaging system. The packaging system may include (i) an inner housing that can encase or otherwise enclose the substrate within its confines; (ii) an outer housing that in turn encases or encloses the combination of the inner housing and the substrate within its confines; and (iii) one or more gaps positioned between the electronic circuitry, inner housing and outer housing. The gaps may be filled with fluid or solid insulating media. The combination of the inner housing, outer housing, and gaps can insulate the electronic circuitry from the detrimental and destructive heating effects when the packaging system experiences short-term exposure to a high temperature, which thereby allows operability before, during and after such exposure.

    摘要: A proximity sensor is provided with a means for sensing an attempt to tamper with the normal operation of a proximity sensor. An Eddy current killed oscillator is used to sense the presence of an undulating magnetic field provided by a coil and a monolithic timing circuit that periodically energizes and deenergizes the coil. A sensing coil is association with an Eddy current killed oscillator to provide an output signal that undulates in response to the undulations of the magnetic field provided by the stationary coil. If the output signal from the Eddy current killed oscillator changes states at a sufficient frequency to continually refresh a retriggerable resettable multivibrator, an output from the multivibrator will remain in a high condition and represent the coincident positions of the zones proximate the output coil and sensing coil. If, on the other hand, an attempt is made to tamper with the sensor by placing a metallic object near the sensing coil, the constant output from the Eddy current killed oscillator will fail to trigger the multivibrator at a sufficient frequency to maintain the high status of its Q output. In addition, the outputs from the Eddy current killed oscillator and the multivibrator are combined to determine that a tamper attempt has been made.
