| 20090016162 | Moving object detection apparatus - A moving object detection apparatus comprises a transmitter, a receiver, a detection portion, a binary conversion portion and a judgment portion. The transmitter emits energy waves with a first frequency to a detection area. When receiving incoming energy waves from the detection area, the receiver generates an electric signal corresponding to the incoming energy waves. The detection portion obtains a detection signal from a reference signal with the first frequency and the electric signal. The binary conversion portion compares the detection signal with a conversion threshold signal to obtain a binary signal. The judgment portion judges whether or not a moving object approaching or leaving the receiver exists in the detection area based on the binary signal. | 01-15-2009 |
| 20100052972 | MOVING OBJECT DETECTION SYSTEM - A moving object detection system is provided with an existence detection part, an integrating part and an existence judgment part. Based on first and second detection signals, the existence detection part calculates a rotation angle of each transition factor that is obtained from the first and second detection signals and rotates around the origin in a two-dimensional coordinate system. The existence detection part is configured so that the rotation angle becomes less than 90 degrees. The integrating part integrates each rotation angle to obtain an integrated angle. The existence judgment part judges whether or not a moving object approaching or leaving a receiver of the device exists in a detection area based on the integrated angle and a threshold angle. | 03-04-2010 |
| 20100225332 | PROXIMITY SENSOR - A proximity sensor has an oscillation circuit, an amplitude measurement circuit, a control circuit and a signal processing circuit. The oscillation circuit has an LC resonant circuit and an oscillation control circuit that is configured to supply an electric current to the LC resonant circuit to generate oscillating voltage across the LC resonant circuit. The amplitude measurement circuit is configured to produce an amplitude signal corresponding to the amplitude of the oscillating voltage. The control circuit is configured to set the negative conductance of the oscillation control circuit to a critical value by which the LC resonant circuit can oscillate based on the amplitude signal. The signal processing circuit is configured to produce a distance signal corresponding to the distance between an object and the sensing coil based on a parameter associated with the negative conductance. | 09-09-2010 |
| 20120087210 | MOVING OBJECT DETECTING APPARATUS - A moving object detecting apparatus includes: a transmitting/receiving unit for radiating an ultrasonic wave and receiving a reflective wave reflected from an object present in a monitoring space; a phase detection circuit for mixing reference signals with a reflective signal and obtaining a pair of Doppler signals each having an amplitude depending on a phase difference from the reference signal, each of the Doppler signals having a different phase from each other; a rotation angle calculation unit for calculating a rotation angle; a cumulative addition unit for accumulating the rotation angle; and a comparison unit for comparing the accumulated rotation angle with a threshold value. In the moving object detecting apparatus, a single ultrasonic vibrator is commonly used in the transmitting unit and the receiving unit. | 04-12-2012 |
