Abstract: A solar module support with at least one switching circuit is provided. When a solar cell module is plugged in a solar module socket of the solar module support, the switching circuit is turned off. When the solar cell module is pulled out from the solar module socket, the switching circuit is turned on. Current originally flows through the solar cell module can flows through the switching circuit alternatively, when the solar cell module is detached from the solar module support.

Abstract: A test board for testing PCBs includes a plurality of signal input terminals, a plurality of signal output terminals connected to the signal input terminals respectively, a standby signal output terminal, and a plurality of switches. The standby signal output terminal is connected to the signal input terminals via the switches respectively.

Abstract: An exemplary apparatus and method for measuring kinetic parameters of a machining tool within a press molding machine includes two magnets and two electrical conductors attached to a machining tool. The two magnets are fixed for producing two magnetic fields that are at an angle to each other. The two electrical conductors are connected to a controller to form two closed loops respectively. Each electrical conductor is located in a corresponding magnetic field and is unparallel to the direction of the corresponding magnetic field. Upon the condition that the machining tool deviates from its axial path, voltages are induced across the two electrical conductors. The controller receives the induced voltages, and determines a velocity of the machining tool's deviation from the axial path.

Abstract: A liquid crystal display (LCD) includes a controller, a source driver, first and second data lines and a data transmission path. The controller outputs first and second image data, and the source driver receives and outputs the first and second image data. The source driver includes first and second data channel circuits and a first repair channel circuit. The first and second data channel circuits respectively output first and second sub-pixel data. The first repair channel circuit is coupled to the controller to receive first repairing data. The first and second data lines are respectively coupled to the first and second data channel circuits to receive the first and second sub-pixel data. The data transmission path includes a redundant line, which is for coupling the first repair channel circuit to one of the first and second data lines, and interlaces with the first and second data lines.

Abstract: A source driver including a first line buffer, a second line buffer, a third line buffer and an analog-to-digital converter is provided. The first line buffer sequentially latches first data bits of values of pixels. The second line buffer sequentially latches second data bits of the values of the pixels. The third line buffer parallelly transfers all the data bits latched by the first and second line buffers. The analog-to-digital converter generates driving voltages for the pixels according to the first and second data bits transferred by the third line buffer, in which the first and second line buffers operate in parallel.
