Abstract: The present disclosure relates to an arc ion coating device and a coating method.

Abstract: A test device is connected to a plurality of electronic devices to test a stability of the electronic devices is provided. The test device includes a parameter setting module, a signal generating module, a communication module, and a monitoring module. The parameter setting module sets test parameters for a test in response to a user input. The signal generating module generates a control signal according to the test parameters set by the user to control the electronic devices to execute operations corresponding to the test parameters. The communication module transmits the control signal to the electronic devices. The monitoring module monitors whether the electronic devices are running in a normal state during the test to determine the stability of the electronic devices and further informs the monitoring result to the user.

Abstract: A four-wheel drive electric vehicle is provided. The vehicle comprises a chassis and a power system. The power system comprises batteries, an electric motor, a DC-DC converter and an electric motor controller which are electrically connected, and the chassis comprises a frame, a transmission/transfer case, a drive shaft, a front axle assembly as well as a rear axle assembly. The transmission/transfer case, the front axle assembly and the rear axle assembly are mounted on the frame. The transmission/transfer case is connected with the rear axle assembly directly and with the front axle assembly via the drive shaft. Under the control of the electric motor controller, the electric motor is driven to rotate by the batteries, whereby a power is transferred from the motor to the transmission/transfer case, and a part of the power is transferred to the rear axle assembly with the other part transferred to the front axle assembly via the drive shaft.

Abstract: A remote computer and method installs a virtual machine and one or more operating systems in cloud servers of a data center. The remote computer determines if each of the cloud servers has been successfully installed the virtual machine. The remote computer obtains the IP address of the cloud servers that have been successfully installed the virtual machine by the virtual machine controlling application. The remote computer sends an operating system image file to each of obtained cloud servers to install an operating system on the virtual machine of each of the obtained cloud servers according to the IP address of the obtained cloud servers.

Abstract: A remote server and method processes a log file generated by a cloud server of a data center. The remote server sets an operating system image file and inserts test commands into the operating system image file and installs the operating system in each cloud server using the operating system image file. The remote server executes test commands and receives a log file from each cloud server. The remote server creates a file name for each log file corresponding to the cloud server and stores the log files into a storage system.

Abstract: The invention discloses a brake auxiliary system having a vacuum container, which comprises an auxiliary power supply, a vacuum pump, a vacuum booster and a vacuum container, wherein the vacuum container and the vacuum booster are both connected with the vacuum pump which supplied power by the auxiliary power supply, a pressure detector and a delay control switch are disposed on the vacuum container, keeping the vacuum degree in the vacuum container within a certain range. The vacuum container of the present invention makes the vacuum pump enable to work intermittently, avoiding frequent start of the vacuum pump when brake and also extending the life of the brake. Because of the pressure detector and the delay control switch, the vacuum inside the vacuum container is kept stable, and the efficiency of vacuum booster is ensured.
