  • Patent number: 11991479
    Abstract: The disclosure provides a time-lapse photographic device. The time-lapse photographic device includes a camera module, a drive module, an environment detection module, and a control unit. The drive module is connected to the camera module to drive the camera module to rotate. The environment detection module is configured to detect an external environment of the time-lapse photographic device to generate an environment detection signal. The control unit is electrically connected to the camera module, the drive module, and the environment detection module. The control unit generates, according to a shooting stop parameter, a plurality of intermittent drive signals to control the drive module, and controls the camera module to shoot at intervals of the drive signals. The control unit adjusts operation of at least one of the camera module and the drive module according to the environment detection signal.

  • 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: 9705231
    Abstract: A protective cover for a network cable socket is disclosed. The protective cover is moveably connected to the network cable socket. The protective cover of the network cable socket comprises a housing and two elastic sheets. The housing is moveably connected to the network cable socket. Each of the elastic sheets includes a fixing portion, an extension arm, a stopper and a guiding ramp. The two extension arms are connected to the two fixing portions, respectively. The two fixing portions are fixed to two sides of the housing, respectively. The two stoppers and the two guiding ramps are formed at the two extension arms, respectively. A distance between the two guiding ramps is larger than the distance between the two stoppers.
