A computer chassis includes a mounting hub configured to be coupled between a display device and a computer support structure and a chassis frame configured to be removably received by the mounting hub. In some examples, the chassis frame comprises a central bracket and a pair of frame arms extending from the central bracket. Each frame arm may be configured to support one or more computer components in a customizable arrangement. The central bracket may include a channel configured to receive a cable connecting a computer component attached to a first one of the frame arms to a computer component attached to a second one of the frame arms. At least a portion of the cable management channel may be disposed between the portions of the mounting hub configured to couple to the display device and computer support structure respectively.

Natural gestures for interacting with spreadsheet documents are provided. A user may interact with a spreadsheet document using a variety of touch-based gestures. Gestures applied to a spreadsheet document may be used for making structural and display changes to the document. For example, gestures may be used on the spreadsheet document for inserting new columns and rows; for revealing hidden columns and rows; for deleting columns and rows; for extending functionalities across columns and rows; for moving objects displayed in a spreadsheet document; and for navigating various parts of a spreadsheet document.

The present disclosure provides a display panel including: a panel main body including a display region, a bendable region and a binding region, wherein a plurality of signal transmission lines extending from the display region to the binding region are arranged in the bendable region; and an enhancement layer in the bendable region of the panel main body and including an electrode layer, wherein the electrode layer includes at least one auxiliary electrode, each auxiliary electrode corresponds to one of the plurality of signal transmission lines, different auxiliary electrodes correspond to different ones of the plurality of signal transmission lines, respectively, and each auxiliary electrode is electrically connected to a corresponding signal transmission line. The present disclosure further provides a flexible display device.

A circuit board includes a board body, a card slot, a release structure, and a transmission mechanism. The card slot is disposed on the board body and adapted for inserting an expansion card. The release structure is rotatably disposed beside the card slot. The transmission mechanism includes a contact part and a stressed part that are linked to each other, wherein the contact part is connected to the release structure. When the stressed part receives an external force, the contact part is moved correspondingly, so that the release structure is rotated relative to the card slot, thereby releasing the expansion card.

A buckle base and buckle-fixing pin combination to be used in fixing a printed circuit board to a sheet includes a buckle base and a buckle-fixing pin. The buckle base is in a generally U-shaped form. The buckle base includes a first leg, a second leg, and a bridge therebetween. The first and second legs are connected to the bridge. The buckle-fixing pin forms a longitudinal slot therein.

A latch mechanism for securing an expansion card assembly in a computer chassis includes a lever, a stop member, a rotary latch, a first biasing structure, and a second biasing structure. The lever includes a latching end and an opposing pinned end. The stop member extends from the pinned end. The rotary latch is connected to the latching end and includes a receiving chamber and a hook structure. The hook structure includes a notch for receiving a stop pin. The first biasing structure extends from the lever into the receiving chamber and is configured to urge the rotary latch into a locked position. The second biasing structure is configured to urge the lever about the pinned end to an open position.

The present disclosure discloses a power management circuit, a chip and an upgrade method therefor, and a server. In the circuit, one terminal of a micro controller unit is connected to a control board and a processor of the chip, and the other terminal of the micro controller unit is connected to a power management integrated circuit unit, a voltage conversion unit, and a voltage regulator unit. The micro controller unit receives operation instructions sent by the control board and the processor, stores the operation instructions, reads a power-on/off operation instruction in the operation instructions that is sent by the control board, and sends the power-on/off operation instruction to the power management integrated circuit unit to enable the power management integrated circuit unit performs corresponding control on the voltage conversion unit and the voltage regulator unit to complete a power-on/off operation on the processor.

The present application discloses an electronic device and a connection module therefor. The connection module includes a first connection piece (1) and a second connection piece (2); side walls of the first connection piece (1) is each provided with notches and a limiting end which are connected to each other and are arranged at an angle; the second connection piece (2) is provided with limiting pieces (12) adapted to be placed at the limiting ends by means of the notches; one of the first connection piece (1) and the second connection piece (2) is provided with a retractable positioning assembly, and the side walls of the other are provided with positioning holes (10) fastening the retractable positioning assembly, so that when the limiting pieces (12) are placed at the limiting ends, the retractable positioning assembly is fastened in the positioning holes (10). According to the connection module, quick assembly is allowed, the connection is reliable, and the problem of falloff caused by relative movement of a plurality of connection pieces in a connection module is solved.
