Abstract: A building management system includes a communications bus, an old master controller device; and slave devices. The slave devices are configured to detect that the old master controller device has stopped communicating over the communications bus and to perform an algorithm to determine a new master controller device from the slave devices. The algorithm is based on a device identifier associated with each of the slave devices. The new master controller device is further configured to assume the functions of the master controller device. The functions of the master controller device include transmitting control signals to the slave devices.

Abstract: An optical light engine (100) includes one or more light-emitting diode (LED) panels (101, 102, 103) that are combined into a common path and directly imaged onto panel device to provide a source of light to a microdisplay panel (109). Preferably, the LED panel (101, 102, 103) is shaped such that the aspect ratio of light propagating the LED panel is substantially equal to the light received at the microdisplay panel (109). An aspect ratio of 4:3 or 16:9 is typically selected in view of the sizes of the LED panels used in the light engine.

Abstract: Exemplary security lighting routines are tailored to disrupt visual perception and/or acuity so as to significantly reduce the ability of a person or persons, who has breached security, to function within a secured space. A routine triggered in response to a security breach includes a flash at a relatively high intensity, some number of times brighter than normal illumination for the space. Some exemplary routines include a warning light and/or a pre-flash light emission such as dim lighting or a flicker, to effectively prepare the person in the space for maximum effectiveness of the flash. Exemplary routines may also include a post-flash sequence of multiple color light emissions, such as alternating emissions in sequence of pulses of different colors of light using emission and/or off time parameters that vary in an irregular manner.

Abstract: The present application discloses methods and systems for augmenting a field of view of a user. In one embodiment, a device may include a detector, a processor, and an array of visual indicators. According to an embodiment of the method, the detector may image an environment. The processor may identify within the environment imaged by the detector an object of interest. The processor may also determine a relative spatial location of the identified object of interest. Further, the array of visual indicators may be used to indicate the determined relative spatial location of the identified object of interest. In particular, a set of one or more visual indicators may be selected that has a relative spatial location in the array of visual indicators that is indicative of the relative spatial location of the identified object of interest.

Abstract: A visible light communication apparatus enables an operator to visually recognize a communication state during visual light communication. The apparatus includes a light emitting section which emits visible light and which includes a modulator, a visible light emitter, a light emitting element and an emission control section which includes a controller and which controls an emission state of the visible light from the light emitting section. The apparatus controls the emission state according to the communication state. It is hence possible for the operator to visually perceive the communication state during the visible light communication.

Abstract: A traffic signal head uses a plurality of LED light sources mounted in one or more containment volumes in a housing. One version uses identical three-color LED light sources distributed through the containment volume: each source having a red light generating element, a yellow light generating element, and a green light generating element. A second version uses identical two-color LED light sources distributed through the containment volume, each source having a red LED light generating element and a green LED light generating element. For the second version, activation circuitry enables individual activation of the red LED elements to produce red signals, individual activation of the green LED elements to produce green signals, and concurrent activation of both types of LED elements to produce yellow signals. Both versions can be electrically configured to display any of the three colors, as well as special symbols-such as directional arrows.
