摘要： Switch boxes and other such utility boxes must some time be monitored by video. And most of the time, they are behind a door for security and safety reasons In order to image them, the imaging system must then be located very close to them, that is, inside the enclosure. Disclosed herein are systems and corresponding methods for imaging and monitoring utility panel elements arranged on a utility surface. Example embodiments include an optical focusing element to focus rays from utility panel elements and image the elements onto an imaging plane that is non-parallel with a utility surface, and an imaging surface configured to acquire a representation of the image. Example systems and corresponding methods provide for thermal imaging of utility panel elements at close proximity to the elements and within an enclosure. An advantage of these systems and methods is that utility panel elements such as fuses and switches may be imaged even when located within an enclosure and remotely monitored.

摘要： An example of a method for identifying objects in video content according to the disclosure includes receiving video content of a scene captured by a video camera, detecting an object in the video content, identifying a track that the object follows over a series of frames of the video content, extracting object features for the object from the video content, and classifying the object based on the object features. Classifying the object further comprises: determining a track-level classification for the object using spatially invariant object features, determining a global-clustering classification for the object using spatially variant features, and determining an object type for the object based on the track-level classification and the global-clustering classification for the object.

摘要： A sensor system according to an embodiment of the invention may process depth data and visible light data for a more accurate detection. Depth data assists where visible light images are susceptible to false positives. Visible light images (or video) may similarly enhance conclusions drawn from depth data alone. Detections may be object-based or defined with the context of a target object. Depending on the target object, the types of detections may vary to include motion and behavior. Applications of the described sensor system include motion guided interfaces where users may interact with one or more systems through gestures. The sensor system described may also be applied to counting systems, surveillance systems, polling systems, retail store analytics, or the like.

摘要： An embodiment of the invention is a camera having a housing, a camera lens disposed at an end of the housing, a box camera mounting part provided on the housing to mount the camera in a box camera configuration, and a dome camera mounting part provided at a front end of the housing to mount the camera in a dome camera configuration. Providing the box and dome camera mounting parts on the housing of the camera enables mounting of the camera in box and dome camera configurations, and allows the user to delay the decision of choosing which configuration, thereby reducing the complexity of engineering design and installation. Furthermore, inclusion of both mounting parts facilitates purchasing and stocking only one configuration of camera, thereby simplifying management of the stocked parts and reducing costs.

摘要： An apparatus for mounting a recessed electric fixture in a hole in a support surface having a housing and flexible member with attached spring clips to secure the housing against the support surface is disclosed. The flexible member and spring clips are attached to the recessed electric fixture by tightening members, and inward pressure applied to the tightening members causes the flexible member to bend so that the spring clips are moved inwardly towards the housing, allowing the spring clips and the flexible member to pass through the hole in the support surface. The flexible member unbends when the pressure on the tightening members is removed, allowing the spring cops to move outwardly from the housing so that a surface-bearing section of the spring clips bears against the back side of the support surface and retains the electric fixture in the support surface hole.
