Abstract: The present invention provides a biomedical monitoring system combining a mobile device. Signals can be transmitted between the sensing device and the mobile device via the audio interface by modulating and demodulating the audio signals or encoding and decoding the digital signals. Thereby, it can be applied extensively to mobile devices having audio jacks and thus bringing more convenience. In addition, because the mobile devices inherently have the functions of operational processes, transmission, storage, interface operations, result displaying, network connection, image extraction, and power supply, the required components in sensing devices can be simplified substantially and hence reducing the volume and the manufacturing cost.

Abstract: A method and system for processing the signals of a touch panel are provided. Therein, the capacitive values of each sensor on the touch panel are successively taken during a period of time. Then, the average capacitive value of each sensor is calculated for computing estimated touch point coordinates. The distance between each two sets of such coordinates sensed respectively at two sensing time points is calculated. If a distance thus calculated is less than a predetermined distance, the two sets of estimated touch point coordinates corresponding to the distance are defined as valid touch point coordinates. If a series of estimated touch point coordinates are successively defined as valid touch point coordinates for a predetermined number of times, the touch point corresponding to each set of valid touch point coordinates in the series is defined as a valid touch point. Thus, the precision of touch point determination is enhanced.
