Abstract: 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.

Abstract: An integrated data concentrator, so-called “sensor hub”, for a multi-sensor MEMS system, implements: a first interface module, for interfacing, in a normal operating mode, with a microprocessor through a first communication bus; and a second interface module, for interfacing, in the normal operating mode, with a plurality of sensors through a second communication bus; the sensor hub further implements a pass-through operating mode, distinct from the normal operating mode, in which it sets the microprocessor in direct communication with the sensors, through the first communication bus and the second communication bus. In particular, the sensor hub implements the direct pass-through operating mode in a totally digital manner.

Abstract: A pointing electronic device is provided with: an inertial measurement module, to generate motion input data, indicative of motion of the pointing electronic device, at an input data rate; a pointing determination unit, to implement a pointing algorithm at a processing data rate based on the motion input data, to generate screen-frame displacement data corresponding to 3D-space movements of the pointing electronic device, the processing data rate being higher than the input data rate. The pointing electronic device is further provided with a rate upscaling unit, interposed between the inertial measurement module and the pointing determination unit, to implement a data-rate upscaling of the motion input data, in order to generate upscaled motion input data to be processed by the pointing determination unit at a data rate matching the processing data rate, via a predictive data reconstruction of missing samples based on the actual motion input data.

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

Abstract: 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.

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: 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.
