  • Patent number: 11023053
    Abstract: Aspects discussed herein are directed to ergonomic pointing device systems. In one example, a pointing device system includes an elongate base member, a sleeve disposed to fit over at least a portion of the elongate base member, the sleeve configured to rotate about the elongate base member in a first direction and slide about the elongate base member in a second direction substantially orthogonal to the first direction, where the sleeve includes a pattern on a surface thereof, and a sensor disposed within the elongate base member and positioned to detect at least one of a rotational movement of the sleeve relative to the sensor and an axial movement of the sleeve relative to the sensor based at least in part on a variation of the pattern within a field of view of the sensor.

  • Patent number: 9137623
    Abstract: One embodiment of the present invention discloses a method and system for implementing concurrent access of multiple bearer protocols in a M2M platform. The method comprises: after receiving an uplink message of a terminal, an access module of a M2M platform determining a bearer type of the uplink message, obtaining corresponding key information of the bearer type, and packaging the key information and an original datagram of the uplink message into an internal message to send to a service module of the M2M platform; and after completing a service processing flow based on the internal message, the service module packaging datagram response contents and the key information into a downlink message to send to the access module, which sends the downlink message to a terminal corresponding to the downlink message based on the key information after receiving the downlink message.
