A system includes an electronic module and an integrated circuit outside the electronic module. The integrated circuit is configured to generate a digital timing signal that emulates a first synchronization signal internal to the module and not available outside the module and to generate trigger signals based on the digital timing signal. A controller is configured to independently and autonomously perform control operations of the electronic module at times triggered by the trigger signals.

When a host-slave system including a host device and a slave device transitions to a power-down mode, the host device drives a CMD line in order of a high level, a low level, and a high level, and stops supplying a clock signal after a predetermined time elapses. During a power-down mode period, the slave device stops supplying a power to a back-end module. When the host device resumes the supply of the clock signal, the host-slave system returns from the power-down mode.

A system includes: a high bandwidth memory (HBM) including a first sensing unit configured to generate one or more first environmental signals corresponding to a first transistor in a first memory cell, and a second sensing unit configured to generate one or more second environmental signals corresponding to a second transistor in a second memory cell; and a differentiated dynamic voltage and frequency scaling (DDVFS) device configured to perform the following (1) for a first set of the memory cells which includes the first memory cell, controlling temperature by adjusting one or more first transistor-temperature-affecting (TTA) parameters of the first set based on the one or more first environmental signals, and (2) for a second set of the memory cells which includes the second memory cell, controlling temperature by adjusting one or more second TTA parameters of the second set based on the one or more second environmental signals.

The present disclosure relates to digital signal processing architectures, and more particularly to a modular object-oriented digital system architecture ideally suited for radar, sonar and other general purpose instrumentation which includes the ability to self-discover modular system components, self-build internal firmware and software based on the modular components, sequence signal timing across the modules and synchronize signal paths through multiple system modules.

A method monitors a sensor clock signal in a sensor unit, which is generated and output for a data transfer between the sensor unit and a control unit with a predefined period duration. A reference clock signal having a predefined reference period duration is received. The sensor clock signal is compared to the reference clock signal. Based on the comparison, a deviation of the current period duration of the sensor clock signal from a target period duration is detected. Based on the detected deviation, a counting pulse or a reset pulse is emitted.

A signal receiving circuit receives a reset configuration signal from an exceptional timing sequence device in a functional module and outputs a trigger signal. A first signal generation circuit generates an idle signal based at least in part on the trigger signal. The idle signal is used to configure a shutdown signal which in turn is used to shut down a first clock signal of the exceptional timing sequence device and a second clock signal in a same clock domain as the first clock signal. A second signal generation circuit generates a reset enable signal based at least in part on the trigger signal. An operational circuit performs an operation based at least in part on the reset enable signal and generates a module-based reset signal based at least in part on an operation result. The module-based reset signal is used to reset the exceptional timing sequence device in the functional module.

A hub may receive event data captured by a body-worn device and store the event data in a memory of the hub. The event data is then backed up from the hub to a memory of an additional hub communicatively connected to the hub. A copy of event data for a predetermined period of time as included in the event data is then transferred from the memory of the hub to a data store of a network operations center (NOC). In response to the transfer being complete, the hub may delete the event data for the predetermined period of time, send a first command to the additional hub directing the additional hub to delete a backup of the event data for the predetermined period of time, or send a second command to the body-worn device directing the body-worn device to delete the event data for the predetermined period of time.

A range sensor and a method thereof. The range sensor includes a light source configured to project a plurality of sheets of light at an angle within a field of view (FOV); an image sensor, wherein the image sensor is offset from the light source; collection optics; and a controller connected to the light source, the image sensor, and the collection optics, and configured to simultaneously determine a range of a distant object based on direct time-of-flight (TOF) and a range of a near object based on triangulation.
