Abstract: A vehicular occupant monitoring system includes a camera disposed at an interior rearview mirror of a vehicle. A polarization filter is disposed between an imaging array sensor of the camera and occupants of the vehicle such that light reflected off of the occupants of the vehicle passes through the polarization filter prior to reaching the imaging array sensor. The vehicular occupant monitoring system, responsive to processing by the image processor of image data captured by the camera, determines presence of an occupant of the vehicle.

Abstract: A vehicular camera includes an imaging array sensor that includes one million photosensors arranged in rows and columns and a microlens array. The microlens array includes a plurality of microlenses disposed at the imaging array sensor. Each individual microlens of the plurality of microlenses includes a respective plurality of refractive indices. The microlens array is disposed at the imaging array sensor so that light incident at the vehicular camera passes through the microlens array to be incident at the imaging array sensor. Light incident at and passing through each individual microlens of the microlens array is incident at a respective sub-array of the photosensors of the imaging array sensor. The vehicular camera is configured to be disposed at a vehicle equipped with a vehicular vision system.

Abstract: A vehicular camera includes an imaging array sensor and a microlens array that includes a plurality of microlenses disposed at the imaging array sensor. Each individual microlens is associated with a respective sub-array of photosensors of the imaging array sensor and has a respective plurality of refractive indices. The microlens array is disposed at the imaging array sensor so that light incident at the vehicular camera passes through the microlens array to be incident at the imaging array sensor. Light incident at and passing through each individual microlens is incident at the respective sub-array of the photosensors. A focus length of at least one microlens of the plurality of microlenses is different from a focus length of at least one other microlens of the plurality of microlenses. The vehicular camera is configured to be disposed at a vehicle equipped with a vehicular vision system.

Abstract: The disclosure relates to textile biosensors and related systems that can be used for in situ health monitoring and disease detection. The biosensors include a flexible or textile substrate, a working electrode embroidered thereon, a reference electrode embroidered thereon, optionally a counter electrode embroidered thereon, and an enzyme probe bound to the working electrode. The biosensors can be integrated directly onto fabrics and garments to provide lightweight, unobtrusive wearable sensing systems that do not compromise wearer mobility, comfort or attention.

Abstract: The subject matter described in this specification is generally directed control architectures for an autonomous vehicle. In one example, a reference trajectory, a set of lateral constraints, and a set of speed constraints are received using a control circuit. The control circuit determines a set of steering commands based at least in part on the reference trajectory and the set of lateral constraints and a set of speed commands based at least in part on the set of speed constraints. The vehicle is navigated, using the control circuit, according to the set of steering commands and the set of speed commands.

Abstract: A flyback converter is provided that includes a high-side synchronous rectifier switch transistor. A secondary-side synchronous rectifier controller powered by a power supply voltage controls a cycling on and off of the high-side synchronous rectifier switch transistor. An active control of the charging of the power supply voltage uses an auxiliary capacitor that is charged from a charge source while a power switch transistor in a first switching state. When the power switch transistor is in a second switching state that is the complement of the first switching state, the active control coupes the auxiliary capacitor to a power supply capacitor that stores the power supply voltage.
