Abstract: A device and method for managing external sensors are disclosed. The device comprises at least one embedded processor and a memory device and at least one bus controller that can be used by the embedded processors to communicate with external sensors. The embedded processor includes a mechanism to receive a control input to retrieve raw data from at least one sensor external to the device. The embedded processors may include another mechanism to receive a control input interrupting the embedded processors at regular intervals of time to retrieve raw data from at least one sensor external to the device.

Abstract: Selectable communication interface configurations for motion sensing devices. In one aspect, a module for a motion sensing device includes a motion processor connected to a device component and a first motion sensor, and a multiplexer having first and second positions. Only one of the multiplexer positions is selectable at a time, where the first position selectively couples the first motion sensor and the device component using a first bus, and the second position selectively couples the first motion sensor and the motion processor using a second bus, wherein communication of information over the second bus does not influence a communication bandwidth of the first bus.
