  • Publication number: 20210320406
    Abstract: An antenna system and an electronic device are provided. The antenna system includes a first substrate, a first antenna group, and a second antenna group. The first antenna group includes four first antennas that are disposed on a peripheral area of the first substrate. The second antenna group includes four second antennas that are disposed in an array on a second substrate. The four second antennas of the second antenna group are disposed above a central area of the first substrate. The central area of the first substrate has a recess. The second substrate is disposed above the recess. A first predetermined distance is defined between a bottom of the second substrate and the recess of the first substrate. A second predetermined distance is defined between the second substrate and the first substrate. The first predetermined distance is greater than the second predetermined distance.

  • Patent number: 7556512
    Abstract: A memory disk structure includes a storage device, a hollow casing, an elastic member and a base. The storage device has a connector and a main body. The connector is installed in one end of the main body. The hollow casing has an opening and a recess with a protrusion. The elastic member and the base are attached to the main body, and the base has an engagement portion. When the connector passes through the opening of the hollow casing to make connector pushed into the hollow casing, the elastic member is deformed to make the engagement portion wedge in the recess and against the protrusion, and when the body is pushed into the hollow casing and the connector is exposed outside the hollow casing, the elastic member is fastened at the first recess to prevent the storage device from departing from the hollow casing.

  • Patent number: 7416423
    Abstract: A portable storage device is provided. A housing has a first opening and a second opening. A storage body has a connector and a pair of positional restriction structures. The storage body slides in the housing to make the connector extend outside the housing or hide in the housing via the first opening. A pair of actuating arms is provided in the housing and can swing. An actuating structure is partially exposed outside the housing via the second opening and pivotally connected to the pair of actuating arms. An elastic element is connected to the actuating structure and the storage body, so that the elastic element pushes the storage body and drives the actuating arms to return to the original position to block the positional restriction structures.

  • Publication number: 20080096425
    Abstract: A portable storage device structure is described. A memory device has a connector and a first concave portion. An opening defined on a hollow housing to form two sections of the hollow housing with different lengths. The longer section has a second concave portion. A resilient member has one end secured to the second concave portion to suspend the opposite end. When the memory device assembles to the hollow housing, the opposite end of the resilient member engages with the first concave portion to avoid the memory device from slipping out of the housing.
