Abstract: A device includes one or more inertial sensors and fusion circuitry coupled to the one or more inertial sensors. The inertial sensors, in operation, generate inertial sensor data with respect to a plurality of axes of movement. The fusion circuitry, in a polar fusion mode of operation, applies a plurality of polar rotation operations to the generated inertial sensor data to rotate the generated inertial sensor data onto an axis of the plurality of axes of movement. A fused data signal is generated based on a result of the plurality of polar rotation operations. The plurality of inertial sensors may include bone-conduction sensors.

Abstract: A remote access device (200) and method of operation thereof are provided for accessing a physical object or location. The remote access device includes an accelerometer (204), a wireless transmitter (206), and control circuitry (202). The control circuitry (202) causes the wireless transmitter (206) to transition between a first operating mode (108) and a second operating mode (110) in response to receiving signals from the accelerometer (204) indicating a first change in motion states of the remote access device. The control circuitry (202) causes the wireless transmitter (206) to transition between the first operating mode (108) and the second operating mode (108) in response to receiving signals from the accelerometer (204) indicating a second change in motion states of the remote access device. The control circuitry (202) further causes the wireless transmitter (206) to transition between the first operating mode (108) and the second operating mode (110) in response to receiving signals from the accelerometer 104 indicating a third change in motion states of the remote access device.

Abstract: An integrated circuit includes a control circuit, a primary sensor device coupled to the control circuit, and a plurality of groups of secondary sensor devices coupled to the primary sensor device. The primary sensor device receives a master clock signal from the control device and outputs, to each group of secondary sensor devices, a respective secondary clock signal with a frequency lower than the primary clock signal. The primary sensor device generates primary sensor data. The primary sensor device receives secondary sensor data from each group of secondary sensor devices. The primary sensor device combines the primary sensor data and all of the secondary sensor data into a sensor data stream with a time division-multiplexing scheme and outputs the sensor data stream to the control circuit.

Abstract: The present disclosure is directed to a device (10) and method for generating and transmitting a TDM signal including both raw data and processed data. The device includes a sensor (18) having a time division multiplexing (TDM) interface (24). The TDM interface (24) transmits both raw data and processed data in a single TDM signal by reserving one or more slots inside a TDM frame for transmission of the processed data. The sensor (18) also embeds additional information inside a data stream of raw data by repurposing one or more of values of the raw data as an exception code, flag, or another type of notification. The device (10) is also enabled to transmit data, and disabled when not in use in order to conserve power.

Abstract: An inertial measurement system (1), having: at least one motion sensor (2) to output motion data with an output data rate - ODR -period (T ODR ); and a control unit (4) coupled to the motion sensor (2) to control operation thereof based on a power mode switching, according to which each ODR period (T ODR ) envisages: a first phase (T OFF ), in which the motion sensor (2) is controlled in a condition of low power consumption; and a subsequent measurement phase (T MEAS ), in which the motion sensor (2) is controlled to perform measurements for generation of measurement data. The control unit (4) adaptively adjusts the duration of the ODR period (T ODR ) based on at least one check related to the measurement data generated during the measurement phase.
