摘要： A system to detect changes in the contents of a defined sensitive volume wherein a detector having an active resonant circuit is connected in an oscillator circuit to create an internal field in the defined sensitive volume, the frequency of the oscillator being shifted by a sudden change in the contents of the defined sensitive volume affecting the internal field. A receiver is coupled to the oscillator circuit and responsive to changes in the frequency of the oscillator to produce an output indicative thereof. Feedback means connected between the output of the receiver and the oscillator provide tracking between the oscillator and the receiver in the zero to low frequency range. Detect means are connected to the output of the receiver to produce a detect signal in response to a change in the contents of the defined sensitive volume affecting the internal field. The system also includes indication means connected to the output of the detect means activated in response to detect signals to provide an indication of a change in the contents of the defined sensitive volume affecting the internal field, and error prevention means connected to the detect means and the indication means operative to prevent activation of the indication means in the event erroneous detect signals are produced.

摘要： A first oscillation circuit in which a helical antenna is used as a part of an element for a resonance circuit and a second oscillation circuit in which a loop antenna is used as a part of an element for a resonance circuit are caused to oscillate at substantially the same frequency. When a human body approaches the helical antenna and the loop antenna, the frequency difference between the first oscillation circuit and the second oscillation circuit increases. This frequency difference is extracted using a BPF.

The proximity sensor chip (IC) includes an internal temperature sensor, senses a first sensing value through the multiple channels, senses a second sensing value through the internal temperature sensor, and compensates the first sensing value through addition or subtraction of the second sensing value with respect to the first sensing value. The internal temperature sensor includes: a clock signal generator including a first oscillator and generating first clock signals variable according to temperature characteristics; and a temperature compensator generating second clock signals according to a setting condition corresponding to the first clock signals generated from the clock signal generator and outputting the second sensing value by counting the second clock signals through a second oscillator generating reference clock signals independent of temperature change.
