Abstract: In an example, a card retainer may include a latch to removably engage with a free end of an expansion card. Further, a card retainer may include a pivot mount to attach the latch to a system board of a computing device. In some examples, the latch is movable about the pivot mount between an open position and a closed position. The latch may exert a bias force on the free end of the expansion card in order to retain the expansion card to the system board in a secure manner when the latch is disposed in the closed position.

Abstract: Examples described herein relate to a non-transitory machine-readable medium consistent with the disclosure. For instance, the non-transitory machine-readable medium may store instruction executable by a processing resource to transfer additional power through a power delivery cable, input the additional power to a component of a computing device, and sequence the additional power with a main power supply of the computing device.

Abstract: A clamping mechanism is provided to clamp a die set on a carrier of a machine. The clamping mechanism utilizes a first pushing block to push a locating shaft of the die set to allow a top surface of the locating shaft to contact a mounting surface of the carrier and utilizes a second pushing block to push the locating shaft to allow a first contacting surface of the locating shaft to contact a reference surface of a cage base such that the die set will not clamp on the carrier of the machine with shift or skew errors.

Abstract: A hydroponic device includes a water tank, a drain pan, a hydroponic module and a light emitting diode module. The water tank delivers water to the drain pan via a drain pump. The water is then dispensed to each pot body of the hydroponic module. Each pot body includes an inner pot and an outer pot. Water inside the inner pot will flow to the outer pot through the draining hole. Water will flow out of an overflow outlet and re-enter the water tank if the water level is higher than the overflow outlet. The light emitting diode module is disposed above the hydroponic module.

Abstract: A portable computer includes a computer body and a keyboard. The keyboard includes a plurality of keys and a space bar. The space bar includes a base frame, a touch pad, an elastic element and a key switch. The touch pad is elevatably disposed on the base frame, and one surface of the touch pad can provide a cursor of the portable computer. The elastic element is disposed between the base frame and the touch pad, and elastically supports the touch pad. The key switch is disposed on the other surface of the touch pad. When one of the keys is clicked, the computer body disables the touch pad and enables the key switch.

Abstract: An electronic device is disclosed, which includes a touch display module, a frame for placing the touch display module, plural elastic pieces extended from a sidewall of the frame, a casing, a fastener, and plural adjusting screws.

Abstract: A memory access method for processing images includes reading an image data from a main memory. The image data has display rows. Inner memories are configured to be memory blocks arranged in an order of data storage. First pixel data in an ith display row are written into the memory blocks in the order of data storage, and N dummy data are written into the memory blocks in the order of data storage to form an isolated block. M dummy data are written into the memory blocks after the isolated block in the order of data storage to form a first shifted block. Second pixel data in an (i+1)th display row are written into the memory blocks after the first shifted block in the order of data storage, and O dummy data are written into the memory blocks in the order of data storage to form a second shifted block.
