Abstract: A time series of face images of a human during a human activity are captured. A first artificial neural network (ANN) processing pipeline processes the captured time series of face images to provide a first attention level indicator signal. An electrophysiological signal indicative of the level of attention of the human during the activity is also captured. A second ANN processing pipeline processes the sensed electrophysiological signal to providing a second attention level indicator signal. A risk indicator signal is then generated based on at least one of the first attention level indicator and second attention level indicator. A user circuit is then triggered as a result of the risk indicator reaching or failing to reach at least one attention level threshold.

CPC classification number: G06F3/017 , H04M1/0281
Abstract: A system and method for determining handedness in a device. The system including a first electrode, a second electrode, a sensor, and a processing circuit coupled to each other. The first electrode is placed at a first location, and the second electrode is placed at a second location on the device—the first location is different from the second location. The electrodes are configured to sense a variation in an electrostatic field in response to a user interacting with the device. The sensor detects a differential potential between the first electrode and the second electrode, and the processing circuit determines whether the user is interacting with the device using a left hand or a right hand. The determining is based on data received from the sensor corresponding to the differential potential.

Abstract: An embodiment method comprises collecting at least one electrophysiological signal of a human over a limited time duration, and computing a set of electrophysiological signal features. The computing comprises at least one of: providing at least one reference electrophysiological signal and applying dynamic time warping processing to the at least one collected and at least one reference electrophysiological signals, applying stacked-auto-encoder artificial neural network processing to the collected electrophysiological signal, or filtering the electrophysiological signal collected via joint low-pass and high-pass filtering. The method further comprises applying pattern recognition processing to the computed set of features, producing a virtual key signal indicative of an identity of the human, and applying the virtual key signal to a user circuit to switch it between a first state and a second state as a result of the virtual key signal matching an authorized key signal stored in the user circuit.

Abstract: In a method of manufacturing a multi-die semiconductor device, a metal leadframe includes a die pad and electrically-conductive leads arranged around the die pad. First and second semiconductor dice are arranged on the die pad. A laser-activatable material is disposed on the dice and leads, and a set of laser-activated lines is patterned, including a first subset coupling selected bonding pads of the dice to selected leads, a second subset coupling selected bonding pads amongst themselves, and a third subset coupling the lines in the second subset to at least one line in the first subset. A first metallic layer is deposited onto the laser-activated lines to provide first, second and third subsets of electrically-conductive lines. A second metallic layer is selectively deposited onto the first and second subsets by electroplating to provide first and second subsets of electrically-conductive tracks. The electrically-conductive lines in the third subset are selectively removed.

Abstract: A circuit includes a memory array with memory cells arranged in a matrix of rows and columns, where each row includes a word line connected to the memory cells of the row, and each column includes a bit line connected to the memory cells of the column. Computational weights for an in-memory compute operation (IMCO) are stored in the memory cells. A word line control circuit simultaneously actuates word lines in response to input signals providing coefficient data for the IMCO by applying word line signal pulses. A column processing circuit connected to the bit lines processes analog signals developed on the bit lines in response to the simultaneous actuation of the word lines to generate multiply and accumulate output signals for the IMCO. Pulse widths of the signal pulses are modulated to compensate for cell drift. The IMCO further handles positive/negative calculation for the coefficient data and computational weights.
