Abstract: A Power Transducer is disclosed, such as a watt-watthour Transducer, having a dual multiplier circuit receiving inputs from a power source to be monitored and a triangle wave generator. The circuit includes first and second transformers which separately receive voltage and current inputs representative of the power line to be monitored. The first transformer provides dual outputs of opposite polarity which are isolated and scaled replicas of the input voltage. The dual outputs are separately channeled through half-wave multiplier paths, to a comparator in each path, which comparators receive the input from the triangle wave generator to produce a pulse modulated output for control of a switch in each path, which switches also receive the current signal from the second transformer. The outputs from the switches have pulse heights proportional to the instantaneous value of the current and pulse widths proportional to the incoming voltage with the integral being equal to the product of the voltage and current.

Abstract: A monitoring apparatus and method are disclosed for monitoring and/or indicating energy that a battery power source has then remaining and/or can deliver for utilization purposes as, for example, to an electric vehicle. A battery mathematical model forms the basis for monitoring with a capacity prediction determined from measurement of the discharge current rate and stored battery parameters. The predicted capacity is used to provide a state-of-charge indication. Self-calibration over the life of the battery power supply is enacted through use of a feedback voltage based upon the difference between predicted and measured voltages to correct the battery mathematical model. Through use of a microprocessor with central information storage of temperature, current and voltage, system behavior is monitored, and system flexibility is enhanced.
Abstract: An electrosurgical dispersive electrode is disclosed that is useful in conjunction with an electrosurgical unit to establish capacitive-coupling with the skin of a patient receiving therapeutic signals from the electrosurgical unit. The electrode includes a metallic plate electrically connectable with the electrosurgical unit to establish a return current path thereto, an insulator engaging the inner (patient) side of the metallic plate to prevent ohmic contact by the plate with the skin of the patient, and a conductive adhesive gel at the outer (patient) side of the insulator so as to be positioned between the insulator and the skin of a patient to bring the skin uniformly in contact with the gel conductor and thereby reduce the impedance, normally associated with capacitively-coupled dispersive electrodes, while retaining uniform temperature distribution.
