摘要:
The disclosure provides for a scanning apparatus. The scanning apparatus may be disposed in a vehicle mirror assembly. The mirror assembly comprises an electrochromic element comprising a first substrate comprising a first surface and a second surface, and a second substrate comprising a third surface and a fourth surface. The mirror assembly further comprises an image sensor directed toward the fourth surface and configured to capture image data of an object through the electrochromic element. A light source is disposed proximate the fourth surface and configured to transmit an emission through the electrochromic element. The image sensor is configured to capture the image data to identify at least one passenger of the vehicle.

Various implementations relate generally to a multi-sensor device. Some implementations more particularly relate to a multi-sensor device including a ring of radially-oriented photosensors. Some implementations more particularly relate to a multi-sensor device that is orientation-independent with respect to a central axis of the ring. Some implementations of the multi-sensor devices described herein also include one or more additional sensors. For example, some implementations include an axially-directed photosensor. Some implementations also can include one or more temperature sensors configured to sense an exterior temperature, for example, an ambient temperature of an outdoors environment around the multi-sensor. Additionally or alternatively, some implementations can include a temperature sensor configured to sense an interior temperature within the multi-sensor device. Particular implementations provide, characterize, or enable a compact form factor. Particular implementations provide, characterize, or enable a multi-sensor device requiring little or no wiring, and in some such instances, little or no invasion, perforation or reconstruction of a building or other structure on which the multi-sensor device is mounted.

A system comprises light intensity detection circuitry and pixel data processing circuitry. The light intensity detection circuitry is operable to determine whether a welding arc is present based on an intensity of light incident captured by the light intensity detection circuitry, and generate a control signal indicating a result of the determination. A mode of operation of the image processing circuitry may be selected from a plurality of modes based on the control signal. The light intensity detection circuitry may comprise, for example, a passive infrared sensor, a photodiode, and/or circuitry of a camera. The pixel data processing circuitry may comprise, for example, circuitry of a camera, a special purpose graphics processing unit, and/or a general purpose processing unit.
摘要:
An optical module that processes an input optical signal and outputs a processed optical signal is disclosed. The optical module provides a housing and an optical processing device in the housing. The housing provides an optical input port and an optical output port in a first wall thereof in side-by-side arrangement. A third wall of the housing only provides RF terminals. Second and fourth walls of the housing provide DC terminals. Electrical connection between the DC terminals with DC pads on the device is realized through a wiring substrate whose top avoids an optical path from the optical input port to the input port of the device.
摘要:
A low-cost, robust method for automatically tuning a coupled resonator to match a wavelength of electromagnetic radiation emitted from an applied laser source. Dithering signals are used for automatic wavelength tuning and thermal stabilization of microring resonators. The disclosed method can be applied using low-speed analog and digital circuitry, to create a complete photonic interconnection network. The methods disclosed also automatically detect, measure, and correct for resonance shift.
