A moisture sensing apparatus includes an oscillator for supplying an AC signal to a driven ring of a sensor having a pad inside the ring, and a ground plate around the ring. An amplifier forms part of a temperature-compensated, precision rectifier, and is connected to the pad. A first diode connected to the output of the amplifier in a feedback loop of the amplifier, where the amplifier nullifies temperature variation effects upon the diode, and supplies a rectified signal which is a function of moisture content of material in contact with the sensor. A second diodes is connected between the amplifier output and other input of the amplifier. The sensor has a rounded configuration to avoid electrostatic field fringing effects, and a passive impedance with both resistive and capacitive members is connected in parallel with the sensor to provide a functional baseline for the rectified signal.

A sensing and indicating device is mounted at a fixed location to determine the distance between the sensor and an approaching vehicle. The sensor provides visual and/or audible indication of the distance between the vehicle and the sensor. The driver of the vehicle uses that displayed or audible information to locate the vehicle within a defined space or envelope, e. g. , within a garage. The sensor and indicator may also be located laterally with respect to the vehicle so that the distance between the vehicle side and the sensor can be determined whereby the vehicle can be located laterally within the defined space or envelope.

An electronic organ has a tone generating system for producing tones corresponding to notes of a musical scale. The tones and combinations thereof are selectable to provide different characteristics or "voices" which duplicate the various voices which are selectable on a pipe organ. The character of each such voice is determined by a single generator. The character of the output tone on a per manual basis is alterable by substituting or combining the outputs of different generators. The signal produced in this manner is sampled at a rate which translates it to an audio frequency.

The video amplifier circuit comprises a complementary symmetrical arrangement of a first and second solid state transistor element with the video input source coupled through a level shifting circuit to the first element and through a DC level shifting circuit to the second element and with means provided for operating each element in a clamped mode approaching saturation. Additional circuit modifications include means for modulating the video input signal with a high frequency signal to cause continuous gray scale variation.

A sensing and indicating device is mounted at a fixed location and uses transmitted and reflected acoustic or electrical energy to determine the distance between the sensor and an approaching vehicle. The sensor provides visual and/or audible indication of the distance between the vehicle and the sensor. The driver of the vehicle uses that displayed or audible information to locate the vehicle within a defined space or envelope, e. g. , within a garage. The sensor and indicator may also be located laterally with respect to the vehicle so that the distance between the vehicle side and the sensor can be determined whereby the vehicle can be located laterally within the defined space or envelope. The device remains active at all times, precluding any need for manual intervention to activate it, without compromising power consumption. A distance dependent means for dynamic desensitization of the receiver subsystem is provided so as to ignore reflection artifacts from irrelevant off-axis objects close to the sensor and to avoid false triggering due to ringing within the sensor.
