Abstract: 1329749 Measuring capacitance NY SAMOILOV 11 Dec 1970 58889/70 Heading G1U In a method of measuring the capacitance C x  of a capacitor connected between terminals 1 by adjusting an alternating reference current I 0  until it balances a current I, substantially proportional to C x , the effect of the known stray inductance L of the leads connecting the capacitor to the terminals 1 is eliminated by adding to I o  a compensating current I k  such that I k  = I o #<SP>2</SP> LC x  where # is the angular frequency. A current comparator 6 detects when I o  + I k  = I x . The current I x  is produced by applying across the unknown capacitor a fixed voltage (from a sine wave generator 2), and the current I o  by applying across a standard capacitor 3 a variable voltage (4) of the same frequency but opposite phase. The current I k  is produced by applying across a further standard capacitor 11 the output voltage of two cascaded voltage dividers 7, 8, the first of which receives the variable voltage (4) and has the means 9 for adjusting its transfer ratio coupled to the means 5 for varying this voltage, and the second of which has its transfer ratio preset in accordance with the stray inductance L.

Filed: 1992-10-06
Abstract: A power control system for a cellular mobile telephone system in which system users communicate information signals between one another via at least one cell site using code division multiple access spread spectrum communication signals. The power control system controls transmission signal power for each cellular mobile telephone in the cellular mobile telephone system wherein each cellular mobile telephone has an antenna, transmitter and receiver and each cell-site also has an antenna, transmitter and receiver. Cell-site transmitted signal power is measured as received at the mobile unit. Transmitter power is adjusted at the mobile unit in an opposite manner with respect to increases and decreases in received signal power. A power control feedback scheme may also be utilized. At the cell-site communicating with the mobile unit, the mobile unit transmitted power is measured as received at the cell-site. A command signal is generated at the cell-site and transmitted to the mobile unit for further adjusting mobile unit transmitter power corresponding to deviations in the cell site received signal power. The feedback scheme is used to further adjust the mobile unit transmitter power so that mobile unit transmitted signals arrive at the cell-site at a desired power level.
