Liquid surface detection device
InactiveUS20070144253A1Increased riskHigh detection sensitivityResistance/reactance/impedenceWithdrawing sample devicesCapacitanceDetector circuits
A liquid surface detector is constituted of an oscillator that outputs an alternating current signal at a frequency of 130 kHz, and a modulator circuit for modulating the alternating current signal with a capacitance index signal that indicates a change in capacitance. The capacitance changes with movement of a suction probe relative to a cup containing a liquid. An output signal of the modulator is filtered and amplified by a first filtering circuit that passes a frequency component of 130 kHz through it. Through a wave detector circuit and a second filtering circuit that passes a frequency component of 2 kHz, a signal corresponding to the capacitance index signal is detected from an output of the first filtering circuit, and is compared with a reference signal, to detect that the probe gets into contact with the liquid surface.

Digital camera
InactiveUS20030030740A1Improve responsivenessReduce noiseTelevision system detailsColor television detailsFrame rateDigital camera
A digital camera includes a CCD imager. If brightness of an object is not enough, a frame rate of the CCD imager at a time of a focus adjustment is changed from 30 fps to 15 fps. This also lowers a reading speed of a camera signal, and reduces noise included in the camera signal. An AF evaluation value is acquired by integrating a high frequency component of a Y signal generated on the basis of the camera signal, and therefore, high noise causes an error in the AF evaluation value and fails to correctly adjust focus. This is the reason why the driving speed of the CCD imager is lowered when the brightness of the object is not enough.
