Digital isolator devices, and many other devices, have a maximum device junction temperature, which, if exceeded, may cause device failure and the integrity of the isolation is no longer guaranteed. The use of an electronic fuse, eFuse, arranged in series with the digital isolator, provides a protection scheme for the digital isolator in which current is limited by the eFuse when it is determined that the supply current of the digital isolator exceeds a predetermined threshold that would the cause junction temperature to increase above an absolute maximum rating. As such, the integrity of the digital isolator is preserved in the event of a system fault.

The present disclosure provides numerous applications for the use of liquid crystal polarization gratings (LCPGs) to controllably steer light. When combined with an image sensor, light generated or reflected from different fields of view (FOV) can be steered, allowing an increase in the FOV or the resolution of the image. Further, the LCPG can stabilize the resulting image, counteracting any movement of the image sensor. The combination of LCPGs and liquid crystal waveguides (LCWGs) allows fine deflection control of light (from the LCWG) over a wild field of view (from the LCPG). Further applications of LCPGs include object tracking and the production of depth images using multiple imaging units and independently steered LCPGs. The LCPG may be used in controlling both the projection and reception of light.

SPI Round Robin Mode for Single-Cycle MUX Channel Sequencing. SPI round robin mode is an SPI mode applicable for MUX devices control. It allows the MUX output to connect to the next input channel sequentially in just one clock cycle. Configurations can be made such as: clock edge to use (rising/falling), ascending/descending channel sequence, and enabling/disabling the channels to go through. The device supersedes an ADC with built in sequencing and is applicable to multiplexing, switching, instrumentation, process control and isolation application&#x2014;while retaining SPI device control and operation.

In electronic systems, the downstream circuitry may be damaged by overcurrent and overvoltage events. Therefore, there is provided a dual protection device for protecting electrical components in electronic systems. The protection device includes a mechanical fuse in conjunction with an electronic fuse, eFuse, the two components connected in series, together protecting against overcurrent events on two levels. The mechanical fuse provides high overcurrent protection, realising fast and reliable protection at high overcurrent events, and the electronic fuse provides low overcurrent protection, realising accurate and resettable protection for low overcurrent events.

The present disclosure relates to performing facial recognition using a single-pixel sensor that measures the time signature of a light pulse reflected from a subjects face. Due to depth differences between the sensor position and different parts of the subject's face reflections of a short duration illumination pulse from the different parts of the subject's face will arrive back at the sensor at different times, thus providing a time-based one-dimensional signature unique to the individual subject. By analyzing the reflection signature using neural networks or principal component analysis (PCA), recognition of the subject can be obtained. In addition, the same system may also be used to recognize or discriminate between any other objects of known shape in addition to faces, for example manufactured products on a production line, or the like.
