  • Patent number: 9210825
    Abstract: A fixing mechanism includes a base, a movable hook and a sliding key. A first end of the movable hook is for fixing an accessory. The sliding key is slidably installed on the base. The sliding key includes a key body whereon a sliding slot is formed, and a driving part for pushing a second end of the movable hook when the key body moves in a first direction so as to separate the first end of the movable hook from the accessory. The fixing mechanism further includes a rotary arm. A first end of the rotary arm is rotatably installed on the base, and a second end of the rotary arm is slidably installed inside the sliding slot. The second end of the rotary arm stops the second end of the movable hook in a closed position for preventing the movable hook from moving in the first direction.

  • Patent number: 9201466
    Abstract: A portable computer includes a base, a display module, a support element and a cam structure. The base comprises a first area and a second area. The display module includes a connecting end and a display face. The support element includes a first end connected pivotally to a portion of the display module other than the display face and a second end connected pivotally to the rear end of the base. Two ends of the cam structure are connected pivotally to the base and the support element. Accordingly, the support element is connected indirectly and pivotally to the base. When the display module is slid and rotated relative to the base to change a notebook state or a tablet state, the support element does not interfere the movement of the display module and keep the flatness of the whole appearance of the portable computer.

  • Patent number: 9120478
    Abstract: Methods and devices are described that utilize skip fire techniques to rapidly meet requests for transitory changes in the output of an engine. Specifically, the fraction or percentage of the working cycles that are fired can be changed during a transitory event so that the engine delivers the desired transitory engine output. Once the transitory event is over, normal engine operation may be restored. The described techniques are useful in a variety of applications that require a relatively quick, but transitory, reduction in engine output to meet vehicle control requirements. One particularly useful application is during transmission shift events. Other representative applications include: loss of traction events, stability control events, wheel hop prevention events, etc.

  • Publication number: 20150233289
    Abstract: Methods and systems are described for detecting valve actuation faults in internal combustion engines operating in a skip fire operational mode. In one aspect, a torque model is used to estimate an expected net torque during a selected operating window. The torque model considers an expected torque contribution from each of the cylinders and accounts for the effects of specific skip fire firing decisions that affect the expected torque contribution from each cylinder. A parameter indicative of the actual engine torque is also measured. Valve actuation faults can then be identified based at least in part on a comparison of the measured parameter to an expected parameter value that is based at least in part on the expected net torque. With the described approaches, the occurrence of the valve actuation fault can be made within one engine cycle of the initial occurrence of the fault.

  • Patent number: 8939780
    Abstract: In a connector structure, a moving element is pushed by a connector to move horizontally with respect to a first housing, while a linking element is moved accordingly by the moving element vertically with respect to the first housing. With such structural relation, the connector structure may be substantially reduced in its thickness before connection with the connector, saving room for the thickness of an electronic device where the connector structure is disposed. As the connector is inserted to the connector structure, the sinked linking element provides necessary structural support for withholding the connector, securing the contact between the connector and a connecting jack of the connector structure, and preventing the connector from detaching from the connector structure.
