摘要:
An AC power supply testing method upon booting a main board is provided. The testing method is applied to a main board, a microprocessor is in connection with the main board, and a relay is connected with the microprocessor, an AC power supply and a system power supply of the main board. The testing method includes steps of (1 ) configuring a system power on/off time of the microprocessor; (2 ) counting down the system power on/off time; (3 ) determining the current state of the relay; (4 ) shutting off the relay and resuming executing step (1) if the current state is ON; and (5 ) executing a power supply testing upon booting if the current state is OFF.

A motor vehicle has an exterior coating. A fluorescing and/or phosphorescing substance is added to the exterior coating or forms a part of the exterior coating. The fluorescing and/or phosphorescing substance serves to emit light, in particular red, green and/or blue light, in a visible range upon irradiation by light in an invisible range.

A display arrangement for a vehicle has, in particular, a multipurpose instrument or is configured as a multipurpose instrument. The display arrangement includes a first display device to display information concerning operation of the vehicle, a glass with adjustable transparency arranged in front of the first display device, with reference to the viewing direction of the display arrangement, and a second display device to display information concerning operation of the vehicle or additional information concerning operation of the vehicle.

A CMOS light-to-current sensor built on silicon substrate is disclosed in this invention. This light-to-current sensor includes a photo-diode and two MOS transistors. The first MOS transistor is connected as the load transistor for the photo-generated current from the photo-diode, and the second MOS transistor is connected as the current-mirror transistor for the first transistor to output a current linearly proportional to the photo-generated current to the external resistor connected to the sensor.

A rearview mirror for a motor vehicle, in particular for a convertible, has a display that displays information by emitting light. A reflective-type linear polarization layer is disposed in front of the display layer, with reference to a defined viewing direction. There is no absorption-type polarization layer disposed in front of the reflective-type linear polarization layer, with reference to a defined viewing direction.

A motor vehicle has a passenger compartment with an interior covering formed with a display region. The display regions is configured to emit visible light upon irradiation thereof with light in an invisible range or an at least virtually invisible range. There is also provided a projection assembly for displaying information or images in the display region by irradiating the display region with such light in the invisible range or the at least virtually invisible range.

A digital video recorder makes use of a flash memory for storage of A/V data to accomplish multiple times of read/write. A programmable digital signal processing (DSP) chip is also provided to integrate various circuits with different functions in a modular way to decrease the number of chips, lower the cost, and increase the reliability. Moreover, the DSP chip can monitor the actions of video playback/recording without connection to an external computer, hence accomplishing easy operation without complex setting. There is also a built-in video recognition trigger mechanism, which can be replaced by an external personal infrared (PIR) circuit to trigger recording actions only when an event takes place. A small-size, low-price digital video recorder of easy installation and high reliability can thus be provided, and can effectively save power to be suitable for home use.
