摘要:
Technology for detecting a change in a configuration position of one or more elements in an illumination system is described. A light source generates an illumination signal, and an element of the system directs a portion of the light of the signal back to a light detector. In one example, the portion of light is reflected back to the light detector. By monitoring an output signal of the light detector based on the directed light, control circuitry can detect that a position of an element of the system has changed. In one example, an off-the-shelf integrated circuit laser diode package including a monitor photodiode can be used with a reflective element. In one example, the reflective element is a tilted optical element. Changes can be detected in the configuration of one or more optical elements of the illumination system which are outside the laser diode package.

A method for constructing a 3D representation of a subject comprises capturing, with a camera, a 2D image of the subject. The method further comprises scanning a modulated illumination beam over the subject to illuminate, one at a time, a plurality of target regions of the subject, and measuring a modulation aspect of light from the illumination beam reflected from each of the target regions. A moving-mirror beam scanner is used to scan the illumination beam, and a photodetector is used to measure the modulation aspect. The method further comprises computing a depth aspect based on the modulation aspect measured for each of the target regions, and associating the depth aspect with a corresponding pixel of the 2D image.

Techniques are provided for determining distance to an object in a depth camera's field of view. The techniques may include raster scanning light over the object and detecting reflected light from the object. One or more distances to the object may be determined based on the reflected image. A 3D mapping of the object may be generated. The distance(s) to the object may be determined based on times-of-flight between transmitting the light from a light source in the camera to receiving the reflected image from the object. Raster scanning the light may include raster scanning a pattern into the field of view. Determining the distance(s) to the object may include determining spatial differences between a reflected image of the pattern that is received at the camera and a reference pattern.
摘要:
A panoramic camera design that is lower cost, robust, stable and more user friendly than prior art designs. The camera design makes use of a unified molded structure of optical material to house a mirror, aligned sensor, and lens assembly. The unified molded structure of the camera keeps the sensed optical path enclosed to minimize dust and user's fingers and maintain optical alignment.

摘要:
Determining a physical location of a network device includes determining a network address associated with the network device and correlating the network address with a physical location. The network address associated with the network device is an address of the network device, an address of a router coupled to the network device or an address of an other device at a same physical location as the network device. The other device may be a gas meter or an electric meter. A table may be consulted for the location information.
