摘要： 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.

摘要： The present disclosure is directed to a device and method for generating and transmitting a TDM signal including both raw data and processed data. The device includes a sensor having a time division multiplexing (TDM) interface. The TDM interface 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 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 is also enabled to transmit data, and disabled when not in use in order to conserve power.

摘要： A remote access device and methods of operation thereof are provided for accessing a physical object or location. The remote access device includes an accelerometer, a wireless transmitter, and control circuitry. The control circuitry causes the wireless transmitter to transition between a first operating mode and a second operating mode in response to receiving signals from the accelerometer indicating a first change in motion states of the remote access device. The control circuitry causes the wireless transmitter to transition between a first operating mode and a second operating mode in response to receiving signals from the accelerometer indicating a second change in motion states of the remote access device. The control circuitry further causes the wireless transmitter to transition between the first operating mode and the second operating mode in response to receiving signals from the accelerometer indicating a third change in motion states of the remote access device.

摘要： An interface electronic circuit couplable to a first transducer that generates a first analog signal indicative of a first quantity and to a microcontroller unit, the interface electronic circuit including: a first conversion stage, which generates a first digital signal as a function of the first analog signal; a DSP stage, which includes at least one DSP unit and generates a processed signal as a function of the first digital signal; an advanced-processing stage, which detects, by execution of a processing of the processed signal, the occurrence of an target condition regarding the first quantity; and a number of registers, which store values of configuration parameters. The advanced-processing stage writes at least one subset of the registers, after detecting the occurrence of the target condition, so as to vary the values of the configuration parameters stored in the subset of registers.

摘要： 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.

摘要： In a digital communication system, a master device and a number of slave devices are coupled in communication with the master device over a shared data communication bus. A selection line for each one of the slave devices couples the master device with a respective slave device and is dedicated to selection by the master device of the respective slave device for communication over the shared data communication bus. Each of the slave devices is able to send an interrupt request to the master device over the respective selection line to be served by the master device initiating a communication over the shared data communication bus, each selection line thereby being a bidirectional communication line between the respective slave device and the master device.
