Filed: 1979-10-08
Abstract: A fuel-gauging system has a capacitive sensor (6) that is mounted in a fuel tank (5) and that is supplied with an alternating electric signal from an oscillator (12). The oscillator output is supplied to a diode-pump circuit (14) that produces a D.C. voltage VDP proportional to the product of the amplitude VP and the frequency f of the oscillator output. The D.C. voltage VDP is supplied to one input of a comparator (22) that receives a constant voltage VR at its other input. The comparator produces a D.C. output voltage VI, dependent on the difference between its inputs, which is supplied to an input of the oscillator, the oscillator being arranged such that the amplitude of its output voltage is dependent upon the amplitude of the input voltage. in this way the product fVP of the amplitude and frequency of the oscillator output is maintained substantially constant. <IMAGE>

Title: Personal alarm
IPC: G08B13/08
Filed: 1980-01-29
Abstract: A personal alarm has a housing 12 nesting in the palm of the hand, and a triggering lever 18 extending along one edge of the housing but projecting slightly therefrom. The natural squeeze reflex action of the hand under the stimulus of fright will cause the hand to close tightly on the housing, thus depressing the lever. By providing a relatively large lever rather than a small button or switch, the user need not be constantly aware of just how the alarm is held, since any squeeze action will depress the lever and set the alarm off. The alarm may be adapted for remote by means of a plug 44 connected to two elongated members 49, 50 biased into the Figure 4 position, the members in use being inserted in a narrow space (e.g. between a door and its frame) so that member 49 cannot contact a terminal 57 and complete an alarm circuit. <IMAGE>
