Abstract: Implementations herein relate to visualization of interaction with a building management system (BMS). Such interaction may be facilitated with a smart headset that displays a three-dimensional model of an image with real-time data from the BMS to enable monitoring and control of the BMS. In one implementation, a system for locating a target in a building includes a server, a first wireless emitter, and an application on a mobile device. The first wireless emitter is associated with the target and configured to emit a first emitter identifier within a first range. The application is configured to detect the first emitter identifier when the mobile device is within the first range. The application is also configured to transmit the first emitter identifier to the server in response to detecting the first emitter identifier. The application is also configured to receive a first content from the server.

Abstract: Systems and methods for detecting and using equipment location in a building management system are provided. Location information is measured by one or more measurement devices at a physical location of building equipment. The measured location information is used to automatically determine the physical location of the building equipment in or around a building. The location of the building equipment is integrated with an architectural model of a building served by the building equipment and a graphical visualization of the integrated model is generated. The location of the building equipment can be used to automatically associate the building equipment with other building equipment or with a building zone, to automatically generate control parameters and control algorithms, and/or to generate an augmented reality display of the building equipment in the building.

Abstract: A controller in a building management system (BMS) includes an integrated wireless network processor chip. The integrated wireless network processor chip includes a wireless radio, a processor, and memory. The wireless radio is configured to exchange data communications with one or more BMS devices controlled by the controller. Both the processor and memory are in communication with the wireless radio and located on the same chip as the wireless radio. The memory includes communication stacks configured to facilitate communications using a building automation and control network communications protocol and a WiFi communications protocol. The integrated wireless network processor chip receives data from the BMS devices via the wireless radio, formats the data using the processor, stores the data in the memory, and sends the data via the wireless radio without requiring any additional processing or communications components outside the integrated wireless network processor chip.

Abstract: A metrology system for measuring aspheric test objects by subaperture stitching. A wavefront-measuring gauge having a limited capture range of wavefront shapes collects partially overlapping subaperture measurements over the test object. A variable optical aberrator reshapes the measurement wavefront with between a limited number of the measurements to maintain the measurement wavefront within the capture range of the wavefront-measuring gauge. Various error compensators are incorporated into a stitching operation to manage residual errors associated with the use of the variable optical aberrator.

Abstract: An multiport, multi-wavelength optical switch having and array of angular beam-directing devices employs an anamorphic optical system that transforms a beam corresponding to a given wavelength of a given multi-wavelength input channel into a beam, at a plane of the angular beam-directing device array, having an elliptical Gaussian-beam waist in the angular-directing direction of the beam-directing device and in the orthogonal direction, with the waist in the angular-direction direction being larger than the waist in the orthogonal direction. Planar and non-planar emitter/receivers for use with the switch are disclosed.

Abstract: An optical fiber collimator (100) in an optical system, includes a pair of optical fibers (108) having emitting cleaved planes (112) to provide a substantially uniform angled side surface for forming a prescribed angle (101) relative to the optical axis (105) of the optical system. The pair of optical fibers (108) are disposed coplanarly in the object plane of the optical system for sharing the optical axis and separated from each other and from the optical axis on the same object plane. Optically coupled to the pair of fibers, a microlens (106) has a sloped rear surface (114) opposite a rotationally symmetric microlens surface (116) which bound a volume having a homogeneous index of refraction. The pair of fibers (108) are positioned near the focal plane containing the optical axis (105) of the microlens for the generation or reception of collimated beams at the prescribed angle (101) relative to the optical axis (105) of the microlens (106).
