  • Publication number: 20170076878
    Abstract: A key assembly configured to an electronic device is provided. The key assembly includes a switch component and a flexible button. The switch component is disposed in a case of the electronic device. The flexible button has a pressing portion, a shaft portion, at least one water-resistant portion and an actuating portion. The pressing portion is exposed from the case. The shaft portion connects the pressing portion and the actuating portion, and passes through a through hole of the case. The water-resistant portion is connected to the shaft portion and covers the through hole. The actuating portion is located in the case and aligned to the switch component. When a force is applied to the pressing portion, the pressing portion produces compressive deformation and makes the actuating portion produce expensive deformation to actuate the switch component.

  • Publication number: 20160096100
    Abstract: A bicycle trainer includes a base frame, a damper unit pivotally connected to the base frame and including a rotating wheel set, a swivel frame pivoted to the base frame and biasable between an inclined position where the swivel frame and the damper unit are capable of supporting a bicycle wheel and a collapsed position where the swivel frame is received in the base frame and the rotating wheel set of the damper unit is disposed adjacent to the swivel frame, and a locking device for locking the damper unit to the base frame or allowing the damper unit to be biased relative to the base frame. Thus, the composition of the invention allows the bicycle trainer to be folded up and received in a compact condition to minimize the dimension convenient for carrying with less effort.

  • Publication number: 20160096098
    Abstract: A bicycle trainer includes a base frame including a first pivot connection part, a damper unit mounted at the base frame, a support frame including a locating portion and a second pivot connection part, which is pivotally connected to the first pivot connection part of the base frame for enabling the support frame to be biased relative to the base frame in direction away from or toward the damper unit such that when the support frame is held in an inclined position relative to the base frame, the locating portion and the damper unit can hold a wheel of a bicycle in place, and a non-return unit mounted at the base frame or support frame and adapted to prohibit the support frame from being biased in direction away from the base frame. The invention enables the support frame to be constrained by the non-return unit.

  • Patent number: 8614995
    Abstract: A method for communication transmission includes the steps of: performing sub-frame transmission in accordance with a first communication standard and pausing sub-frame transmission in accordance with a second communication standard in a first communication period; performing a sub-frame uplink operation in accordance with the second communication standard and pausing a sub-frame uplink operation in accordance with the first communication standard in a second communication period; and performing a sub-frame downlink operation in accordance with the second communication standard and pausing a sub-frame downlink operation in accordance with the first communication standard in a third communication period. The transmission band of the first communication standard overlaps, at least partially, the transmission band of the second communication standard.

  • Patent number: 8279812
    Abstract: A module constructs a frame for communication in a communication system that supports a new standard and a legacy standard, the new standard being backward compatible with the legacy standard. The module comprises a first frame generator configured to generate a first portion of the frame, the first portion of the frame to support a first set of data to be transmitted in the legacy standard in each of a number of first bands, a second frame generator configured to generate a second portion of the frame, the second portion of the frame to support a second set of data to be transmitted in the new standard in a second band composed of the first bands, and a frame constructor configured to construct the frame based on the first portion of the frame from the first frame generator and the second portion of the frame from the second frame generator.

  • Publication number: 20120120583
    Abstract: An electronic apparatus is disclosed, which comprises: a casing, a cap, a data storage unit and an ejecting module. The casing has an accommodation space formed by the enclosure of two sidewalls of the casing. The accommodation space is further configured with an opening that can be covered by the cap so as to seal the accommodation space. The ejecting module is comprised of: a holder, pivotally coupled to one of the two sidewalls while clamping the data storage unit; and a first elastic element, disposed at a position for allowing the same to be compress when the opening is covered by the cap, and consequently, enabling the first elastic element to be released from the compression when the cap is removed from the opening, and thus bringing along the holder to rotate in a specific direction for lifting and exposing the data storage unit out of the accommodation space.
