Abstract: An approach is provided that filters out inadvertent contact with a touch pad input device. A filter area is defined within a surface of a touch pad input device that is accessible from an information handling system, such as a computer system. When a user of the information handling system contacts the surface of the touch pad, an input stream is received. The input stream includes an origination point where contact was initially made by the user. If the origination point is within the defined filter area, then the input stream is filtered out (not processed). On the other hand, if the origination point is outside of the defined filter area, then the input stream is processed by the information handling system.

Abstract: In an information transmitting device, a variable capacitor which is charged to have a predetermined voltage discharges through a predetermined resistor. Until the voltage becomes lower than a predetermined threshold voltage, the number of AC signals having a predetermined frequency is counted. Accordingly, first continuous amount information of a binary code corresponding to a writing pressure is obtained and is converted to a Gray code, which is regarded as second continuous amount information. A resonant circuit is opened or shorted in accordance with ‘0’ or ‘1’ in the second continuous amount information, so as to transmit the second continuous amount information.
