  • Publication number: 20240141939
    Abstract: A chassis quick release device includes a housing including a base with a connected sliding channel and accommodating space therein and a cover assembled with the base, a locking block linearly movably set in the accommodating space, and an operating handle having a rod body positioned on the sliding channel and a grip assembled with the rod body. The rod body has a cylindrical joint that corresponds to the grip and has a shaft groove defined therein. The grip is provided with a sleeve corresponding to the cylindrical joint and defining therein an accommodating cavity. Moving the operating handle in the direction of the housing causes the locking block to slide out from the accommodating space to form a locked state. Pulling the operating handle away from the housing causes the locking block to move linearly in a second direction to form an unlocked state.

  • Publication number: 20240113032
    Abstract: Interconnect structure packages (e.g., through silicon vias (TSV) packages, through interlayer via (TIV) packages) may be pre-manufactured as opposed to forming TIVs directly on a carrier substrate during a manufacturing process for a semiconductor die package at backend packaging facility. The interconnect structure packages may be placed onto a carrier substrate during manufacturing of a semiconductor device package, and a semiconductor die package may be placed on the carrier substrate adjacent to the interconnect structure packages. A molding compound layer may be formed around and in between the interconnect structure packages and the semiconductor die package.

  • Patent number: 9523837
    Abstract: A lens module includes a driving device, an image sensing device, a lens group frame, and an infrared filter. The driving device has a lens barrel for an optical signal passing through. The image sensing device is on a path of the optical signal to convert the optical signal into an electric signal. The lens group frame is provided in the lens barrel, and has a main body, which is driven by the driving device to be moved between a first position and a second position, and a lens holder, which is pivotally connected on the main body and is swung between a third position and a fourth position when the main body is respectively at the first and the second positions. The infrared filter is provided on the lens holder, and is precisely aligned with the image sensing device when the lens holder is at the fourth position.

  • Publication number: 20160241770
    Abstract: Disclosed is an IP camera and a video playback method thereof, the IP camera connected to a host through the network, the IP camera includes an image capturing unit, a processor, and an input/output buffer unit. An external video is captured by the image capturing unit, and the external video includes a plurality of frames. An image outputting rate is determined by the processor, and an output external image is produced by reducing a resolution of the external image and remarking a confirm flag in at least one first frame when an image output rate is lower than a threshold value. The external image or the processed image is inputted to the I/O buffer unit to form an output external image. By way of the present invention, the captured video may still be watched instantly and fluently on the host while the host is suffering from the network congestion.

  • Patent number: 7728396
    Abstract: A method and a structure are provided for preventing lift-off of a semiconductor monitor pattern from a substrate. A semiconductor structure and a semiconductor monitor structure are formed on a substrate. A material layer is formed covering the semiconductor monitor structure. A part of the semiconductor structure is removed without removing the semiconductor monitor structure, by using the material layer as an etch protection layer. A mask for the method is also provided. The mask includes a clear area and a dark area. The dark area prevents a semiconductor monitor structure from being subjected to exposure so as to form a material layer covering the semiconductor monitor structure and prevent removal of the semiconductor monitor structure from the substrate while a part of a semiconductor structure is removed.
