  • Patent number: 10964990
    Abstract: An electrical combination includes a battery pack and a power tool. The battery pack includes two battery pack connectors which are connected with the same electrode of a battery of the battery pack. A circuit of one battery pack connector has a resistance greater than that in another circuit of another battery pack connector. The power tool includes corresponding tool connectors. When the battery pack is connected with the power tool, the power tool is supplied with a small current by the battery pack firstly, and then is supplied with a large current, so the electric spark is eliminated when the terminals of the battery pack contact with the terminals of the power tool.

  • Patent number: 10459234
    Abstract: The present disclosure relates to head-mounted displays (HMDs) and HMD controllers and to managing low power situations. As the HMD and controller are operational, the HMD monitors the energy level of the batteries. If the HMD detects that a battery energy level is below a first threshold, the HMD sends a low battery command to a developer application. The low battery command causes the developer application to enter a low battery mode in which it performs operations that encourage the user to charge the battery. If the energy level of the battery continues to decrease, the HMD may detect the battery energy is below a second threshold. As a result, the HMD and controller enter into a pass-through mode. In a pass-through mode the HMD projects a representation of an operating environment of the HMD in a display of the HMD.

  • Patent number: 10310566
    Abstract: The present disclosure provides a foldable mechanism of a mobile terminal and the mobile terminal. The foldable mechanism includes a soft support structure and a hard support structure embedded in the soft support structure. The foldable mechanism formed by the soft support structure and the hard support structure embedded in the soft support structure is used as a component for connecting a first housing and a second housing. When the mobile terminal is unfolded, the foldable mechanism formed by the soft support structure and the hard support structure is unfolded and turns into a flat structure connected to the first housing and the second housing. When the mobile terminal is folded, one side of the soft support structure away from the hard support structure shrinks inward. Therefore, the mobile terminal is prevented from having an abrupt exterior structure, and an exterior effect of the mobile terminal is improved.

  • Patent number: 10283975
    Abstract: A modular recharging system includes an electronic device that performs diagnostics on a removable battery pack that the electronic device can use to boost the power of its internal battery. Typically, the battery pack will have a larger battery than the internal battery of the device. The electronic device determines whether the battery pack will take a charge before determining whether the battery pack is authorized to assure that an authorization failure is not due to other issues such as a dead battery, an underpowered battery, or a broken connection between devices.

  • Patent number: 10250050
    Abstract: The charger includes a housing with a base wall opposite a face wall. A male electric power plug has prongs which extend from the face wall to connect to an AC power output receptacle. Intermediate walls extend from the base wall to the face wall including a top wall, a bottom wall and a pair of side walls. Lateral edges are located between the intermediate walls. A USB port, a cord, or other power outlet is located along at least one of these lateral edges, and in some embodiments multiple outlets extend from multiple edges. The charger can thus be utilized in one AC power output receptacle within an array of AC power output receptacles without blocking adjacent AC power output receptacles, and provide one or more sources of DC power to power and/or recharge portable electronic devices.
