First Claim
Patent Images
1. An information processing apparatus comprising:
- generator means for generating an alternating current signal;
inducing means for inducing said alternating current signal to a human body, such that the human body generates an induced signal; and
a detector for detecting and phase locking the induced signal with said alternating current, wherein the detector includes a latch circuit configured with the induced signal as an input and said alternating current signal as a clock.

Abstract
When a human body touches any of linear electrode array mutually isolated and arranged in X and Y directions of an input device, an inducing signal from wiring of a commercial power supply is transmitted by way of the human body, so that an inducing voltage is generated at the linear electrode to which the human body touches. The input device detects the inducing voltage and outputs the detected inducing voltage to a signal processing section. The signal processing section detects a coordinate where the input device detects the inducing voltage, identifies a frequency of the inducing signal transmitted by way of the human body, and outputs the information to an output terminal.
