摘要： One example includes an atomic optical reference system. The system includes an optical system comprising a laser configured to generate an optical beam. The system also includes a vapor cell comprising alkali metal atoms that are stimulated in response to a modulated beam corresponding to an amplitude-modulated version of the optical beam. The system also includes a detection system configured to monitor at least one detection signal corresponding to light emitted from or absorbed by the vapor cell and to generate at least one feedback signal in response to the at least one detection signal. The system further includes a beam modulator configured to amplitude-modulate the optical beam to generate the modulated beam and to frequency shift the optical beam to generate an output beam having a stable frequency in response to the at least one feedback signal.

摘要： A vehicle includes a light switch for manually operating a lighting state of a lighting device. The light switch includes a light-off position and an auto-light position for executing an auto-light process. A vehicle control system includes a first controller for executing an automated driving of the vehicle, and a second controller for controlling a lighting state of the lighting device based on a request from the first controller or operation information of the light switch. The first controller is configured to transmit an auto-light request for executing the auto-light process to the second controller during execution of the automated driving. The second controller is configured to execute the auto-light process when the auto-light request is received from the first controller in a state where the light switch is operated to the light-off position.

摘要： An optical probe includes an optical source that generates an optical beam that propagates from a proximal end to a distal end of an optical fiber that imparts a transformation of a spatial profile of the optical beam. An optical control device imparts a compensating spatial profile on the optical beam that at least partially compensates for the transformation of the spatial profile of the optical beam imparted by the optical fiber in response to a control signal from a signal processor. A distal optical source generates a calibration light that propagates through the one or more optical waveguides from the distal end to the proximal end of the optical fiber. An optical detector detects the calibration light and generates electrical signals in response to the detected calibration light. The signal processor generates the control signal to instruct the optical control device to impart the compensating spatial profile on the optical beam that at least partially compensates for the transformation of the spatial profile of the optical beam imparted by the optical fiber.

摘要： A two-way communication Geographic Lighting Central Management System (GLCMS) to determine roadway lighting performance. Points, lines, polygons, etc, are used to define multiple geographic features overlaid on each other in a municipality relationships to dynamically establish street lighting performance including brightness, color temperature, and light distribution. The geographic data is accessible through a wide range of sources, and the geographic relationship between the data sources determines the lighting performance. Geographically represented features include, but are not limited to, lighting and associated infrastructure, pedestrian conflict, crime, roadway classifications, intersection classifications, lighting layouts, vehicular traffic volumes and road surface reflectance classifications.

摘要： Intelligent synchronization of media or other material output from multiple media devices is contemplated. The intelligence synchronization may include instructing the media devices to coordinate playback in concert with a conductor whereby the conductor acts a focal point or reference for the non-conducting media devices. The non-conductor may transmit sync messaging having data or other information sufficient to facilitate coordinating operation of the non-conductors in a manner sufficient to synchronize output of the media.

摘要： The present disclosure provides a system, method, and computer program for conditioning a building environment based on occupancy estimates. In one embodiment, the method includes tracking the user's entries to and exits from the building on a mobile device associated with the user for each of a plurality of users. Entry and exit event data from the users' mobile devices are used to estimate occupancy of the building. The conditioning of the building environment is adjusted in accordance with changes in occupancy estimates. In certain embodiments, where the building has a plurality of zones, each entry and exit event may be correlated with one of the plurality of zones. Occupancy is estimated within each zone using the zone-correlated entry and exit events. Alternately, users' locations within the building may be estimated using an indoor localization technique. Each zone is then conditioned in accordance with the occupancy of the zone.
