Patent number: 8890596Abstract: A clock signal generating apparatus includes a first frequency generating circuit, a second frequency generating circuit, and an output circuit. The first frequency generating circuit is arranged to generate a first clock signal having a first oscillation frequency. The second frequency generating circuit is arranged to generate a second clock signal having a second oscillation frequency. The output circuit is arranged to receive the first and second clock signals. The output circuit is able to output one of the first and second clock signals as an output clock signal according to an oscillation frequency control setting provided by an external bounding pad included within the clock signal generating apparatus.Type: GrantFiled: June 25, 2012Date of Patent: November 18, 2014Assignee: MediaTek Singapore Pte.

Patent number: 8751182Abstract: In a system and method for testing a serial port of a computing device, the serial port electronically connects to a test fixture. Test data is sent to a receive data (RXD) pin by a transmit data (TXD) pin. A test result is received from the serial port by the RXD pin. The TXD pin and the RXD pin work normally if the test data is identical to the test result. When voltages of a request to send (RTS) pin and a data terminal ready (DTR) pin are set at high level, the RTS pin, a data carrier detect (DCD) pin, the DTR pin, a ring indicator (RI) pin, a data send ready (DSR) pin and a clear to send (CTS) pin work normally, upon the condition that status values of the serial port indicate the voltages of the above six pins are at high level.Type: GrantFiled: August 15, 2011Date of Patent: June 10, 2014Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Zhi-Jian Long, Ming-Xiang Hu, Jun-Min Chen, Le Lin, Xiao-Fei Chen

Publication number: 20120124242Abstract: In a method for testing a preboot execution environment (PXE) function of a NIC of a server, an IP address is allocated for the NIC by sending a DHCP offer message to the NIC in response to receiving a DHCP discover message from the NIC. TFTP parameters are provided to the NIC by sending a DHCP ACK message to the NIC in response to receiving a DHCP request message from the NIC. A connection based on a MTFTP or a TFTP between the BMC and the NIC is established according to the TFTP parameters. A PXE image file is provided to the NIC for downloading through the connection in response to receiving a request for downloading the PXE image file from the NIC, and the downloaded PXE image file is executed to test whether the PXE function of the NIC is normal.Type: ApplicationFiled: July 28, 2011Publication date: May 17, 2012Applicants: HON HAI PRECISION INDUSTRY CO., LTD., HONG FU JIN PRECISION INDUSTRY(Shenzhen) CO., LTD.Inventors: XIAO-FEI CHEN, JUN-MIN CHEN, ZHI-JIAN LONG, LE LIN, MING-XIANG HU
