    摘要： A method of sensing and creating an output to the rate of change of speed includes creating an electrical pulse in timed relationship to the parameter of speed, amplifying the pulse and electrically shaping it to approach a more nearly squared configuration, using the shaped pulse to cyclically switch related switching means to and from a conductive state in order to develop a related saw-tooth like output voltage, electrically averaging the output voltage and employing same for an indication of the then value of speed, applying the output voltage to two electrically responsive sensing means, and preventing one of the sensing means from responding to the output voltage whenever a change in the parameter of speed occurs while permitting the other sensing means to respond thereby creating a triggering voltage to control the action of an output switch in that the output switch becomes responsive to such a condition of change of speed.

    摘要： A pressure differential sensing device has a housing divided into two chambers on opposite sides of a diaphragm contained therein; a first of the two chambers has conduit means adapted for connection to the inlet of a fluid pump while the other chamber has a first conduit connected to the discharge of the fluid pump and a second conduit leading to some associated device to be controlled thereby; a valve carried by the diaphragm is urged into seating engagement with the inlet end of the second conduit by a spring so as to prevent communication between the other chamber and the second conduit whenever the differential of pressure between the pump inlet and pump outlet is less than a predetermined magnitude.

    摘要： A device for detecting the formation and presence of frost, ice or snow on a surface employs signal-producing sensing means to sense the temperature of the surface, as well as the presence of either free water, frost, ice or snow. The signals produced in response thereto are compared to certain established reference values indicative of freezing temperature as well as relative electrical conductivity of free water, frost, ice or snow in order to logically determine whether it is merely free water which is being sensed or if it is actually frost, ice or snow and in accordance with such determination create an appropriate output response.

    摘要： The structure for electronic signal switching disclosed includes trigger signal producing structure, including a transformer having primary and secondary windings and means for controlled shielding of the secondary winding from the primary winding to produce coupling of the transformer windings only when a trigger signal is desired. In one modification of the invention the trigger signal producing structure is included in signal switching structure substituted for the usual breaker points in a vehicle spark ignition circuit and the shielding between the primary and secondary windings of the transformer is accomplished by a slotted rotating rail or cup positioned in the vehicle distributor cap and rotated in accordance with engine speed. In this embodiment of the invention a blocking oscillator provides a continuous electric signal to the primary winding of the transformer which is a bifilar wound coil, the secondary winding of the transformer energizes a semiconductor sensing unit, which in turn energizes a switching semiconductor connected to make or break the vehicle ignition circuit in the manner of the usual breaker points. In a second embodiment of the invention the switching circuit is a darlington amplifier, an integrating circuit receives the output of the blocking oscillator to turn the amplifier on, and a silicon controlled rectifier is connected to short the integrating circuit and turn the amplifier off when the secondary winding of the transformer is not shielded from the primary winding thereof. The amplifier in this embodiment is connected to conduct current through a load, such as an amplifier in an ignition circuit. Both embodiments of the invention may be compensated for voltage variations and temperature by known voltage regulating circuits and commercially known compensating circuits. The second embodiment of the invention may be implemented by commercially procurable voltage and temperature compensated integrated semiconductor circuits. The method of producing electronic signal switching comprises producing trigger pulses by means of controlled shielding of an energized transformer primary winding from the transformer secondary winding and providing switching in accordance with energizing of the transformer secondary winding.
