A preboot execution environment (PXE) test device includes a microprocessor, one or more indicators, a network interface, a power connector, and a storage device. The network interface connects the PXE test device with a computer. The power connector connects an external power source to supply a voltage to the PXE test device. The storage device stores a boot loader, an embedded operating system, and one or more programs. The microprocessor executes the boot loader and the embedded operating system to start the PXE test device. The one or more indicators indicate a power supply status and a starting status of the PXE test device. The microprocessor further executes the one or more programs to remotely boot the computer for test PXE of a network card in the computer.

Preboot execution environment test device and method

A method tests hard disk ports located on a motherboard of a computing device. Each of the hard disk ports connects to a respective serial port of a test fixture. The test fixture includes a group of serial ports, a multiplexer and a storage device. Each of the hard disk ports is selected to be tested during the process of hard disk ports test. A data transmission path is formed by building a connection between the storage device and a channel of the multiplexer corresponding to the hard disk port. Data are written to the storage device and read from the storage device through the data transmission path. The hard disk port is working normal if the written data are identical to the read data. The hard disk port is not working normally if the written data are not identical to the read data.

A sectional electric drive vehicle includes a first motorcycle having a master electric control unit, a second motorcycle detachably connected to the first motorcycle in tandem by a connection mechanism and the second motorcycle including a slave electric control unit, and a system connector detachably connecting the master electric control unit and the slave electric control unit, to allow signals transmission between the master and slave electric control units. When the first and second motorcycles are combined and connected together via the connection mechanism and the system connector, the slave electric control unit relinquishes control to the master electric control unit, and the master electric control unit controls the cooperative motion of the first and second motorcycles. When the first and second motorcycles are detached, the first and second motorcycles are independently operable.

A personal alarm system can help a user to wake up in a preset time. A sensor can sense operations of the personal alarm system and output sense signals. A control unit can calculate a sum of the sense signals to obtain a number of operations of the personal alarm system, and stop an alarm from sounding in response to the sum of the sense signals meeting the condition to stop the alarm from sounding.

Personal alarm system

An electronic device having a temperature sensor is provided. The temperature sensor detects information of a touch operation from an object on a surface of the temperature sensor, determines if the touch operation is valid by determining if the detected information meet preset standards, and executes a corresponding command to activate an action of the electronic device, in response to a determination that the touch operation is valid.

Electronic device and method of controlling the electronic device

A method for testing the accuracy of real time clocks is disclosed. The method includes the steps of: setting test parameters for testing the accuracy of real time clocks (RTCs), the test parameters comprising a test time length, a test time sampling interval, and an acceptable margin; synchronizing the time of an RTC IC and an RTC to be tested via a UUT; reading a current time of the RTC IC and the RTC via the UUT at each test time sampling interval; calculating a time difference between the current time of the RTC IC and the RTC via the UUT, and measuring whether the absolute value of the time difference is less than the acceptable margin; detecting whether the test time length is over; repeating the test process if the test time length is not over, or outputting test pass information if the test time length is over. A related system is also disclosed.
