Patent number: 8886996Abstract: A debugging device for performing a debugging process through an electronic device external connector system is provided. The debugging device performs the debugging process to a target system, and the device comprises a first external connector, a switch, and a debugging module. The first external connector is connected to the external port of the target system. The switch is connected to the first external connector, and the switch chooses to activate the debugging process. The debugging module is connected to the switch, and the debugging module receives a universal asynchronous receiver/transmitter (UART) signal provided by the target system.Type: GrantFiled: April 2, 2012Date of Patent: November 11, 2014Assignee: Compal Electronics, Inc.Inventors: Chih-Chung Yang, Chun-Sheng Chen, Hsin-Hung Shen

Patent number: 8607077Abstract: A multi-function integrated device and an operating method thereof are provided. The multi-function integrated device includes a data reading module, a network access module, and a power control module. The network access module includes a first network component corresponding to a LAN and a second network component corresponding to a WLAN. The power control module turns on the function of the data reading module and/or the network access module according to a control signal received from a host. When the function of the network access module is determined to be turned on, the power control module supplies power to the first network component or the second network component according to the control signal.Type: GrantFiled: February 3, 2010Date of Patent: December 10, 2013Assignee: Compal Electronics, Inc.Inventors: Chun-Yen Lu, Hsin-Hung Shen

Patent number: 8307228Abstract: An integrated network chip and an electronic device using the chip are illustrated. The integrated network chip includes at least a first access interface, at least a second access interface, a power management unit (PMU) and an interface bridge. The first access interface and second access interface respectively provides the electronic device with a local area network connection function and a memory card access function. The interface bridge integrates the first access interface and second access interface by providing a hub-like functionality. The PMU provides the power and the ground to the first access interface, second access interface and the interface bridge. When the PMU detects the second access interface enters a power saving mode, the PMU provides a lower operation voltage to the second access interface.Type: GrantFiled: February 25, 2010Date of Patent: November 6, 2012Assignee: Compal Electronics, Inc.Inventor: Hsin-Hung Shen

Publication number: 20110210754Abstract: A capacitance sensing module adapted to an electronic apparatus having a first body and a second body hinged to the first body is provided. The capacitance sensing module includes a capacitance sensor and a metal conductor. The capacitance sensor is adapted to be fixed in the first body. The metal conductor is adapted to be fixed in the second body. When the metal conductor is moved towards the capacitance sensor along with the movement of the second body with respect to the first body and thus a capacitance sensed by the capacitance sensor changes, the capacitance sensor generates a command to start a default function of the electronic apparatus.Type: ApplicationFiled: October 8, 2010Publication date: September 1, 2011Applicant: COMPAL ELECTRONICS, INC.Inventor: Hsin-Hung Shen
