  • Patent number: 9164643
    Abstract: A method for controlling an input device is provided. The input device has a resistor matrix having M first traces, N second traces and M×N resistors. Each second trace is coupled to a reference resistor and M?1 variable resistors. M and N are integers greater than 1. A first voltage level of each second trace is measured when a first voltage is applied to a first end of the reference resistor and a second voltage is applied to first ends of the M?1 variable resistors via the M first traces. Variations of the first voltage level of each second trace are measured, such that it could be determined whether any touch point of the input device exists according to the variations of the first voltage level of each second trace.

  • Publication number: 20140325311
    Abstract: A hybrid error correction method and a memory repair apparatus thereof are provided for a dynamic random access memory (DRAM). The memory repair apparatus includes a mode register and a hybrid error correction code and redundancy (HEAR) module. When the DRAM enters a standby mode, the mode register switches the DRAM to be controlled by the HEAR module. The HEAR module generates parity data of the error correction code within a default refresh period. The HEAR module extends the refresh period of the DRAM and uses the parity data for error detection to locate a data retention error in the DRAM until the maximum allowable refresh period supported by the HEAR module is reached. Before the DRAM returns to a working mode from a standby mode, the HEAR module performs an error correction process according to fail bit data and writes corrected data into the DRAM.

  • Publication number: 20130335357
    Abstract: A cover glass pressure-sensitive button for a mobile device is disclosed, a piece of pressure sensor is configured under peripheral of a cover glass for a display of a mobile device. The cover glass can be pressed like a button, and a signal is output from the pressure sensor to trigger a predetermined function for the mobile device when a pressure is applied on the cover glass. In another embodiment, a space is reserved either under the touch panel or under the LCD module. With this configuration, the pressure sensitivity of the cover glass increases because the pressure applied on the cover glass can be fully transferred onto the pressure sensor.
