Title: Battery state of charge evaluation
Inventor: LOWNDES M W
IPC: G01R31/36
Filed: 1983-11-25
Abstract: A microprocessor based state of charge evaluator for the traction battery 10 of an electric vehicle evaluates the state of charge and displays it on a dashboard mounted meter 64. The battery is divided into nine 24V sub-packs. During both discharge and recharge, the battery current is integrated to obtain a value representing the charge withdrawn. During discharge, the current is adjusted to compensate for the rate of discharge. During the first part of each discharge, the state of charge is calculated from the charge withdrawn value and from a value representing the charge storage capacity of the battery 10. During the last part of discharge, the state of charge is evaluated from the voltage of the sub-pack having the lowest voltage after compensating for polarization voltage. Polarization voltage is calculated as a function of time and of battery current. The state of charge value obtained from the lowest sub-pack voltage is also used to up-date the charge storage capacity value. <IMAGE>

Title: Method and apparatus for detecting hydrocarbons on the surface of water
Inventor: BARRINGER ANTHONY R
IPC: G01N21/21
Filed: 1985-01-15
Abstract: A method of detecting the presence of hydrocarbons on the surface of a body of water utilizes the fact that, at the Brewster angle, reflections are largely polarized. One part of the radiation received is passed through a filter with its polarizing axis horizontal, and another part is passed through a filter with its polarizing axis vertical, so as to eliminate the surface reflection. The two parts are then combined, to enhance the image with respect to reflected radiation. An apparatus is provided comprising two receivers, e.g. television cameras, 7,8 and associated filters and means 10 for combining the output of the two receivers, preferably by subtracting, 10, a signal generated by the camera with the vertically-polarising filter, from the output of the camera with the horizontally- polarising filter. <IMAGE>

Title: Capacitance measurement
Inventor: SHEFFER TZAFRIR
IPC: G01R17/06
Filed: 1986-04-22
Abstract: An apparatus for measuring an unknown capacitance Cx by comparing (22) the output (20) of a voltage attenuator (18) with the voltage (Vx) at a tap between two series capacitances supplied with a common input voltage (Vf). The attenuator attenuates the input voltage in response to a digital value generated by a successive approximation register (24) supplying a digital output relating the unknown capacitance to a known capacitance. The apparatus is adapted to ratiometrically measure a first inherent capacitance (Ca, Fig. 5) by supplying the common input voltage (Vf) to a series circuit, including a known reference capacitance (Cra) and the first inherent capacitance (Ca). A second inherent capacitance Cf is then measured by supplying the common input voltage to a series circuit, including the first and second inherent capacitances. The value of the unknown capacitance (Cx) is determined by supplying the common input voltage to a circuit comprising the unknown capacitance (Cx) and the first inherent capacitance (Ca) with or without a reference capacitor (Cf), and the measured value is then corrected by the amount of the second inherent capacitance (Cf) appearing in parallel with the unknown capacitance during measurement thereof. <IMAGE>
