  • Patent number: 12010811
    Abstract: A cable clip assembly for a computing device includes a primary clip with a primary surface between first and second primary ends. The first side extends in a first transverse direction from the first primary end, and the second side extends in the first transverse direction from the second primary end. Cable-receiving holes are arranged longitudinally between the first and second sides. A secondary clip has a secondary surface and is attached to the primary clip via the first and second sides. The secondary clip is movable relative to the primary clip between a cable installation position and a secured cable position, and is removably attached at one or more of the first and second sides. A compressible interface is attached to the primary surface, includes a flexible material that compresses when subjected to an installation force, and creates an airflow barrier in an installed position within the computing device.

  • Patent number: 11965522
    Abstract: An impeller includes a hub and a plurality of blades. The blades are arranged around the hub, and each blade includes a leading edge, a blade tip, a root portion, a trailing edge, a windward side and a leeward side. The windward side including a first turning point and a second turning point, a first vertical height difference is formed from the blade tip to the first turning point, and a second vertical height difference is formed from the first turning point to the second turning point, and the first vertical height difference is greater than the second vertical height difference. The impeller apparently reduces the noise.

  • Patent number: 11929561
    Abstract: An antenna module includes a first antenna radiator including a feeding terminal, a second antenna radiator, a first ground radiator, a second ground radiator and a capacitive element. The second antenna radiator is disposed on one side of the first antenna radiator, and a first gap is formed between a main portion of the second antenna radiator and the first antenna radiator. The first ground radiator is disposed on another side of the first antenna radiator, and a second gap is formed between the first antenna radiator and the first antenna radiator. The second ground radiator is disposed between the second antenna radiator and the first ground radiator, and a third gap is formed between the second ground radiator and a first branch of the second antenna radiator. The capacitive element is disposed on the third gap and connects the second antenna radiator and the second ground radiator.

  • Patent number: 9158423
    Abstract: A method for detecting presence of an interference source is to be performed by a touch sensing system that stores a threshold capacitance difference. The method includes the steps of sampling capacitances periodically within a time period for obtaining a base capacitance value; sensing a comparison capacitance after the time period; computing an absolute difference between the comparison capacitance and the base capacitance value; and determining that the interference source is present when the comparison capacitance is smaller than the base capacitance value and the absolute difference is greater than the threshold capacitance difference.

  • Patent number: 9080850
    Abstract: A touch and proximity sensing device includes a circuit board and a sensed signal processing unit including only one sensed signal conversion engine. The circuit board includes a capacitor sensing electrode and a grounding conductor foil disposed on opposite surfaces of the circuit board, and has a proximity sensing electrode formed thereon. The grounding conductor foil is spaced apart from the proximity sensing electrode in a planar direction parallel to the surfaces of the circuit board. The sensed signal conversion engine is spaced apart from the capacitor sensing electrode and the proximity sensing electrode in the planar direction and detects electric sensed signals from the capacitor sensing electrode and the proximity sensing electrode.

  • Publication number: 20140124348
    Abstract: A keyboard device including a lower cover, an upper cover for covering the lower cover and a keyboard module is provided. The lower cover has a plurality of hook structures, and the keyboard module includes a plurality of key caps and a plurality of scissor-type connecting elements. The plurality of hook structures are connected with the plurality of scissor-type connecting elements, and the plurality of scissor-type connecting elements are connected with the plurality of key caps. As a result, the lower cover is able to connect with the plurality of key caps without an additional base plate such that the cost of the keyboard device can be decreased and the volume of the keyboard device can be reduced.

  • Patent number: 6335806
    Abstract: A document pressing structure is provided in a flatbed scanner for facilitating close contact between a document to be scanned and a scanning platform to maintain a constant depth of field. The document pressing structure includes a first coupling element mounted on the cover of the scanner, and a second coupling element mounted on the housing of the scanner. The first and the second coupling elements engage with each other when the cover is pivotally put down on the scanning platform so as to allow the cover to press a scanned face of the document close to the platform.
