摘要： An electronic switch of the type uses a piezoresistive Wheatstone bridge configuration to sense pressure. The output of the Wheatstone bridge is applied to an electronic control circuit which contains a comparator. The comparator monitors the output of the bridge and if the output voltage of the bridge exceeds a predetermined value, as indicated by the comparator, a switch is closed to illuminate a lamp indicating to the operator that the pressure has been exceeded. One terminal of a resistor is connected to an output of the bridge. The other terminal of the resistor is coupled to a switch which when operated, causes the resistor to be connected in parallel with one of the arms of the bridge, thereby producing an imbalance of the bridge. This imbalance, due to the shunting of the arm of the bridge by the resistor, causes the electronic control circuit to recognize an excessive pressure, whereby the electronics control circuit generates an output signal which causes the electronic switch to close, thereby illuminating the lamp.

摘要： There is disclosed an electronic single pole double throw switch which completely replaces a prior art mechanical switch. The mechanical switch normally exists in a suitable vehicle, such as an aircraft or any device, but basically has three output terminals. Two terminals are associated with a first and a second lamp, which lamps have one terminal coupled to an operating voltage. Essentially, in order to replace the mechanical switch, an electronic switch also is wired to the three terminals exactly as a mechanical switch would be so wired. The electronic switch has two states. In each state, one of the lamps is on and the corresponding switch is closed. In this state, the other lamp is off, with its corresponding switch open. This operation is the same operation as that of the mechanical switch. In the electronic switch, the voltage, which is at the output terminal of the lamp that is off, is utilized to drive a low voltage regulator which operates electronic circuitry associated with the electronic switch. The electronic switch contains a timing oscillator which produces a pulse of a narrow interval. This narrow pulse is utilized to supply operating potential to a piezoresistive bridge circuit. The activation of the bridge circuit causes the bridge circuit to produce an output during the pulse interval, which output is directed to a differential amplifier and then to a comparator. The comparator receives an operating voltage during the pulse interval and compares the pressure of the bridge circuit against a threshold pressure. If this threshold pressure is exceeded, the comparator causes a flip-flop to change state. The flip-flop has first and second outputs, each coupled to an associated switching circuit. Each switching circuit will activate an associated lamp to cause the lamp to illuminate when the flip-flop is in a given state. The state of the flip-flop can be changed during the next pulse interval if the pressure applied to the bridge circuit changes.

摘要： A transducer is implemented to operate with transmitted frequency signals. These transmitted signals provide a bias potential to the transducer and enable the transducer to transmit a transducer output signal to a remote location. The transducer has an antenna for receiving transmitted signals. The antenna is coupled to a rectifier circuit; the rectifier circuit is operative to provide a DC voltage in response to said received transmitted signals. This DC voltage is applied to the piezoresistive array via a switching arrangement coupled between the array and the rectifier circuit. An interface circuit controls the switching arrangement to enable DC bias to be applied to the array in a first mode and to remove the bias in a second mode.

摘要： An improved gas leak detection apparatus is disclosed for detecting a leak in a gas containing vessel of constant volume which compensates for deviations in behavior of a contained gas from an ideal model. The apparatus incorporates a pressure transducer, an amplifying means and a feedback means and operates to effectively and accurately model the van der Waals equation of state for gasses. The apparatus is adaptable for operation with any number of different gases by simply changing the values of specific circuit elements. The output of the apparatus is proportional to the total number of moles of gas present in the containment vessel at any particular time, and will thus indicate a leak from the vessel upon a reduction in that number of moles, absent an intentional reduction of the mass of gas in the vessel.
