The method then includes outputting a gaze information about the human user. The gaze information includes the two-dimensional spatial coordinates each of which is in reference to a time in a two-dimensional space.

Abstract: Apparatus and methods for setting and clamping a node voltage are provided herein. In certain embodiments, a node control circuit includes a setting circuit for setting a voltage of a node based on a set signal. The node control circuit further includes at least one of a p-type follower clamp for clamping the node to an upper voltage limit based on an upper clamping control signal or an n-type follower clamp for clamping the node to a lower voltage limit based on a lower clamping control signal. When including both clamps, the node operates with a voltage level set by the set signal, but saturates at the upper voltage limit established by the upper clamping control signal and at the lower voltage limit established by the lower clamping control signal.

Abstract: Pixelated-LED chips and related methods are disclosed. A pixelated-LED chip includes an active layer with independently electrically accessible active layer portions arranged on or over a light-transmissive substrate. The active layer portions are configured to illuminate different light-transmissive substrate portions to form pixels. Various enhancements may beneficially provide increased contrast (i.e., reduced cross-talk between pixels) and/or promote inter-pixel illumination homogeneity, without unduly restricting light utilization efficiency. In some aspects, a light extraction surface of each substrate portion includes protruding features and light extraction surface recesses. Lateral borders between different pixels are aligned with selected light extraction surface recesses. In some aspects, selected light extraction surface recesses extend through an entire thickness of the substrate. Other technical benefits may additionally or alternatively be achieved.

Abstract: A passive vehicular heatstroke prevention system monitors carbon dioxide (CO2) and infrared (IR) energy levels to determine whether a child is present inside a closed vehicle, and, if so, monitors the temperature in the vehicle and, if the temperature in the vehicle exceeds at least one preset critical value, automatically lowers the temperature in the vehicle and contacts the driver/caregiver and/or emergency personnel. The system detects the presence of a child in the closed vehicle by detecting a critical level of carbon dioxide in the air within the vehicle, while monitoring the interior vehicle temperature and takes corrective action to prevent the temperature from exceeding a preset value, such as by activating the vehicle's air conditioning unit and lowering the vehicle's windows, as well as contacting the driver/caregiver and/or emergency personnel.
