Abstract: A crash detection system includes first and second sensors and a processor. The processor receives first sensor data output by the first sensor, determines whether the first sensor data indicates a first class or a second class, outputs an enable signal to the second sensor if the first sensor data indicates the second class, receives second sensor data output by the second sensor after the enable signal is output, determines whether the second sensor data indicates a high acceleration value, determines whether the first sensor data indicates the first class within a predetermined amount of time after the second sensor data is determined to indicate the high acceleration value, and outputs a signal indicating a crash has occurred in response to determining that the first sensor data indicates the first class within the predetermined amount of time after the second sensor data is determined to indicate the high acceleration value.

Abstract: A level shifter having current boosting stages is provided. The level shifter includes a level shifting stage including a plurality of transistors and first and second nodes. The level shifting stage is configured to transfer a first signal of a first voltage domain to a second signal of a second voltage domain. A plurality of current boosting stages are associated with the transistors, respectively. A first current boosting stage provides a first boosting stage current path to support a first level shifter current path of a first transistor of the plurality of transistors in response to: a first supply voltage of the first voltage domain being greater than a second supply voltage of the second voltage domain, the first signal having a first logical state and the first node having a logical state reflecting that the first signal has a second logical state different from the first logical state.

Abstract: Disclosed herein is hardware for easing the process of changing the execution mode of a virtual machine and its associated resources. By adopting the hardware, it is possible to trigger a change in the execution mode in an automatic way, without software intervention, and without interfering with the execution of other virtual machines. In addition, in case an error has occurred for a virtual machine and it is detected, the hardware can be used to disable the resources associated with that virtual machine and generate notification of the completion this operation to other hardware, which will complete the reset of the virtual machine. By adopting the hardware, the execution mode change is simplified and offers configurability and flexibility for a system running multiple virtual machines.

Abstract: Various embodiments of the present disclosure disclose decoding techniques for mitigating data corruption due to duty cycle distortion, jitter, and other distortions to a digital signal. Decoding processes, apparatuses, and systems are provided that utilize a decoding framework for improving the accuracy of output bit streams generated from digital signals. An example process receives data indicative of a digital signal, generates a signal measurement for the digital signal that includes signal length descriptive between a two rising edges of a digital signal or two falling edges of the demodulated digital signal, and generates at least one portion of an output bit stream for the digital signal based at least in part on the signal measurement.

Abstract: According to an embodiment, a method for a touch scan is proposed. The method includes operating a device in first and second modes corresponding to the device, respectively, being wirelessly and not wirelessly charged. In each mode for each frame, the method includes dividing a frequency range corresponding to a touch-sensing technology into M or N positive integer numbers of equal and sequential frequency intervals, where N is greater than M. In the first mode, the method includes determining a first frequency interval of the M frequency intervals with the least noise and performing the touch scan using a first frequency within the first frequency interval. In the second mode for each frame, the method includes determining a second frequency interval of the N frequency intervals with the least noise and performing the touch scan using a second frequency within the second frequency interval.

Abstract: An electronic circuit includes image acquisition cells, wherein each cell has a photodetector coupled to a first node of the cell, and an amplifying transistor having a gate connected to the first node, a conduction node coupled to an output of the cell, and a node for controlling a back gate voltage. The amplifying transistor is configured so that its threshold voltage varies according to the back gate voltage. A control circuit adjusts a voltage applied to the control node of the back gate voltage of the amplifying transistor of one of the cells according to a comparison of the voltage present at the cell output and a reference voltage.
