20130088247 | READOUT APPARATUS AND READOUT METHOD FOR SENSOR ARRAY - A readout apparatus and a readout method for a sensor array are provided. The readout apparatus includes a switching circuit, a control unit, a gain circuit and an offset compensating circuit. The control unit controls the switching circuit to perform a switching operation for selecting a target sensor from a plurality of sensors of the sensor array. The gain circuit selectively senses the target sensor according the switching operation of the switching circuit, and gains the sensing result to output a gained sensing value of the target sensor. The control unit further dynamically decides a compensating value according the switching operation. The offset compensating circuit adjusts the gained sensing value for outputting a compensated sensing value of the target sensor in accordance with the compensating value. | 04-11-2013 |
20130167651 | ELECTRICAL PROPERTY MEASURING APPARATUS FOR PRESSURE SENSOR AND MEASURING METHOD THEREOF - An electrical property measuring apparatus for pressure sensor includes a first plate, a second plate, an object to be measured, an electrical property measuring unit used for measuring the electrical properties of the object, and a fluid supplying system.
