Abstract: A power source module for powering a motherboard comprises a rectifier circuit, a controlling unit, and a leakage protection circuit. The rectifier circuit electrically connected with the motherboard converts the input voltage into the first voltage configured for powering the motherboard. The controlling unit electrically connected with the motherboard outputs the control signals based on an operation state of the motherboard. The leakage protection circuit electrically connected with the controlling unit guides the control signals into a signal line before the motherboard being powered. The leakage protection circuit avoids the control signals to the component of the motherboard, and an operation time sequence of the component is not disturbed before being powered. A power distribution board and a server system are also disclosed.

Abstract: A memory device includes a first transistor, a second transistor and a third transistor. The first transistor is coupled to a first word line at a first node. The second transistor is coupled to a second word line different from the first word line at a second node. A control terminal of the first transistor is coupled to a control terminal of the second transistor. The third transistor is coupled between a ground and a third node which is coupled to each of the first node and the second node. In a layout view, each of the first transistor and the second transistor has a first length along a direction. The first transistor, the third transistor and second transistor are arranged in order along the direction. A method is also disclosed herein.

Abstract: A fingerprint identification apparatus includes a cover plate, an optic fingerprint identification device, and an adhesive. The optic fingerprint identification device has a light-transmitting window. The adhesive is disposed between the cover plate and the optic fingerprint identification device, and a projection of the adhesive on the cover plate surrounds a projection of the light-transmitting window on the cover plate.

Abstract: A controller receives an M-bit input and generates, in response, an S-bit upper range binary data feeding S-bit high range DAC and an R-bit lower range data feeding an R-bit low range DAC. The controller detects transition points in the M-bit input and in response, adds a transition data to the S-bit data equal to at least one least significant bit of the S-bit data and subtracts a value from the R-bit data equal to the transition data. The transition points and the transition data are detected and added at points avoiding such transitions at a full scale value of the R-bit data.

Abstract: The present invention discloses a non-invasive blood pressure measurement apparatus and a safety protection method. In addition to a main pressure measurement circuit and a main microprocessor circuit, the measurement apparatus also includes an independently disposed assist pressure measurement circuit and an independently disposed assist microprocessor circuit. In normal measurement, the assist microprocessor circuit periodically samples a cuff pressure via the assist pressure measurement circuit, and compares the measured cuff pressure with a specified overpressure protection value, and if the cuff pressure exceeds the specified overpressure protection value, the assist microprocessor circuit outputs a control signal to open a deflation valve until the pressure falls to below the safety pressure.

Abstract: A disk holding device for packaging hard drive disks includes a base and a cover. The base includes a central portion and at least one locking surface near an end of the base. The cover includes a latch arm near one end of the cover. The latch arm has a locking tab that transversely protrudes from the latch arm in a direction from the central portion of the base toward the end of the base. A space extends between the cover and the base for receiving a cassette portion when the locking tab is received against the at least one locking surface.
