electrical contact sensors, and human interface device using the same

摘要

The present invention discloses a human interface devices using sensors and electrical contact them. The sensor is in electrical contact with the reference signal generating section for generating a reference signal, and the reference signal by delaying the first signal generator for generating a first signal, having a contact pad, and wherein when the reference contact of the contact pad More than a signal delay of the first signal, when the non-contact and a second signal generator for generating a second signal with a delay smaller than the first signal to the reference signal, the second in synchronization with the first signal receiving a signal to be generated characterized in that it includes a contact signal for generating a touch signal. Therefore gives the service reliability of the operation by making the conductivity can be determined accurately if the contact or without contact with the object with a predetermined charge storage capacity, even more insufficient. Also gives only one of the contact pads to contact to determine the presence or absence of contact with an object to reduce the layout of the product.
