摘要:
Host writes may be handled differently from background writes to non-volatile memory systems. As a result of using different write algorithms for host writes and backgrounds writes, maximum system lifetime and the maximum system performance may be improved in some embodiments.

A custom bracket hinge which is used a single time during assembly of the log splitter, and a customized shipment stand allow an extremely quick and safe method of swinging two heavy parts of a log splitter trailer together, without lifting either part off of the ground until they are mated and can be swung into position. The first method aspect of the invention consists of the use of the special equipment (double hinge bracket mechanism and stand) to assemble the log splitter in a very small number of steps. The second method aspect of the invention is shipping the log splitter with the equipment, in a much smaller footprint.

A card connector includes an insulating housing, a plurality of contacts, a projection and a detecting contact set. The insulating housing includes a bottom wall, a right wall and a left wall for defining a receiving space. The contacts are received in the insulating housing. The projection is protruded from the right wall and into the receiving space, which includes a slanting surface slanted relative to the right wall. The detecting contact set is fixed in the insulating housing, which includes a contacting arm protruding from the slating surface of the projection and into the receiving space. Due to the contacting arm of the detecting contact set is protruded from the slanting surface of the projection in the receiving space, the detecting contact set will be actuated while a card is inserted into the receiving space correctly and completely. Since, the detecting accuracy of the card connector is improved.

A digital photo frame (DPF) includes a power source, a display panel, a light detector, a motion detector, a processing unit, and a power management unit. The light detector is configured to detect the ambient brightness. The motion detection unit is configured to detect whether anyone is around. The processing unit is connected to the light detector and the motion detector. If the motion detector detects someone is around the DPF and the light detector detects the ambient brightness is below a predetermined value, the processing unit controls the power management unit to provide power to the display panel.

An electrical connector includes a plug connector, a receptacle connector and a locking element. The plug connector includes an insulating housing, a plurality of terminals mounted into the insulating housing, a shell wrapping the insulating housing. The locking element fixed on the plug connector has a top plate, two opposite sides of the top plate are extended downwards to form a pair of locking plates. A front side of the locking element is extended perpendicularly and outwardly to form at least one connecting arm. A top side of the connecting arm is extended frontward to form a locking arm. The locking arm has a front end extended perpendicularly to form a locking end. When the plug connector is inserted into the receptacle connector, the locking element hooks locking potions provided by the receptacle connector to ensure the connection stability between the plug connector and the receptacle connector.
