Abstract: A transceiver in a lighting system may include a digital isolation component having multiple channels and an isolation barrier. The digital isolation component may accept an outbound digital signal or an inbound digital signal. On a first channel, the outbound signal may be modulated with a high-frequency signal, and provided across the isolation barrier to the non-isolated side. On the non-isolated side, a modified outbound signal may be generated based on the modulated high-frequency signal. On a second channel, the inbound signal may be modulated with a high-frequency signal that is provided across the isolation barrier to the isolated side. On the isolated side, a modified inbound signal may be generated based on the modulated high-frequency signal. The transceiver may include a voltage level comparator configured to adjust voltage levels of the signals, or an edge transition or duty cycle balancer configured to adjust edges of the signals.

Abstract: Disclosed are examples of hyperspectral imager-equipped lighting devices that provide general illumination supplied by artificial or natural light, and that also detect environmental conditions in the environment around the lighting device. The hyperspectral imager detects light within a contiguous spectral band from the environment in the vicinity of the lighting device. In response, the hyperspectral imager generates image data representative of the spectral intensity of one or more subsets of a continuous spectrum of wavelengths of the detected light. A controller may analyze the image data generated by the hyperspectral imager and may initiate action to control operation of the light source or building management products based on an environmental condition detected by the analysis of the generated image data.

The first controller also overrides the illumination state of the first light fixture based on the gas concentration data received from the at least one gas concentration sensor by controlling the first light fixture in an alert state that is different from the illumination state.

Abstract: An example of a technique for maintaining a previously calibrated mobile device positioning system to account for changes in perturbers of the Earth's magnetic field. A mobile device obtains a corrected heading estimate of the mobile device within a space based on a previously recorded heading correction value. The mobile device also calculates a device heading relative to a previously orientated map of the space. The mobile device subsequently updates the heading correction value with any deviation between the corrected heading estimate and the calculated device heading.

Abstract: An optical system and method provides at least one, and preferably an array of relatively small, high brightness light sources with a surrounding surface that exhibits brightness, thereby reducing the contrast between the high brightness produced by the light sources and the brightness of their surrounding surfaces. The optical system includes a light waveguide structure that captures a portion of the light from the individual high-brightness light sources, and then re-emits the source light to create brightness in the light sources' surrounding surfaces. The optical system is particularly adapted for use with LEDs, but could be used with LEDs, but could be used with other high brightness light sources.

The optic may include a lens and may conform to the shape of the circuit board.

Abstract: Optics for asymmetrically redirecting light from one or more light engines include a dome optic, and first and second reflecting surfaces. The dome optic refracts light emitted by the light engines. The first reflecting surface redirects at least a portion of the light that is initially emitted toward a backward horizontal direction, toward the forward horizontal direction. The first reflecting surface extends substantially vertically and along a transverse horizontal direction, proximate to and behind the dome optic, and has a height greater than or equal to a height of the dome optic. The second reflecting surface reflects downwardly at least a portion of the refracted light that is initially emitted in the forward horizontal direction. The second reflecting surface is proximate to the dome optic and forward of the dome optic, and forms an angle of 45 degrees or more with respect to vertical.

Abstract: A loadable cassette holds a planar light source, such as a flat OLED panel, along with a companion driver board in a manner that allows both the light source and driver board to be operatively and replaceably connected to a luminaire or lighting system. The cassette maintains an air gap between the light source and driver board so as to prevent heat produced by the driver board from damaging the light source.

Abstract: The examples relate to various implementations to enable simultaneous controllable lighting distribution and a wide angle image light output from areas of a luminaire. An example of such a luminaire includes image light emitters and an array of general illumination light emitters for general illumination. A grid structure that has a supporting grid of rows and columns with intersection points and transparent sections or gaps is used to maintain a spaced arrangement of the general illumination light emitters and the image light emitters. Each of the transparent sections is bounded by individual structural members of the grid meeting at individual intersection points. In a specific example, image light emitters are located at intersection points of the grid structure. The general illumination light emitters are optically coupled for emitting general illumination light through the transparent sections of the grid.

Abstract: The examples relate to implementations of apparatuses, such as lighting devices, and a system that uses a speech-based user interface to provide speech-based navigation services. The speech-based user interface provides navigation instructions that direct a person to the location of an item within a premises. The person interacts with a speech-based apparatus to receive the navigation instructions as speech-based directions through the premises from a specified location to the item location, or as static navigation instructions enabling the person to navigate from the specified location to the item location. A directional microphone and a controllable speaker receive audio inputs from and output audio outputs to a specified location or subarea of the premises to a person using the speech-based user interface. The audio outputs are directed to the person in the subarea of the premises, and have a higher amplitude within the subarea than outside the subarea of the premises.

The light fixture further includes a wireless radio transceiver configured to receive transmissions of audio content to be played through the at least one audio speaker module, and an audio driver circuit configured to receive power from the power connection and to drive the at least one audio speaker module. The at least one audio speaker module is rotatable with respect to the housing via the at least one rotatable coupling.

Abstract: Examples of systems and method track a location of an asset within a space using an asset tag location estimation system, track movement of a selected user, or user's mobile device, using a positioning system, and associate the tracked asset with the selected user, or user's mobile device, based on a determination of a trajectory of the asset and the mobile device. Trajectories of the user/mobile device and the asset tag may be determined by a backend server. The trajectory of the selected user/mobile device and the trajectory of the asset tag are compared by the backend server to determine a correspondence between the respective trajectories based on a predetermined correspondence criteria. The determined correspondence indicates that a user of the corresponding mobile device is moving the asset. In response to the determined correspondence, the backend server associates the asset tag to the selected user/mobile device in a database.
