Abstract: An autostereoscopic display device comprises a display arrangement such as an emissive display arrangement or an reflective display arrangement, with an array of spaced pixels. A light guiding arrangement has an array of light guide columns, with one column over each display pixel or over a group (such as a column) of pixels. The light guide columns comprise aside wall which tapers outwardly to define a funnel shape with the pixel at the smaller base of the funnel. The funnel provides collimation to reduce cross talk in the display, which is particularly problematic for 3D autostereoscopic displays.

Likewise, a user may cause one or more attributes of light emitted by a local lighting system to be published, so that other remote lighting systems may follow the local lighting system.

Abstract: An electrical trainline junction box formed from a housing having first and second opposing sides, an identification module positioned in the housing, and first and second receptacles positioned in each of the first and second opposing sides. The first and second receptacles have a plurality of electrical contacts arranged in a predetermined geometry so that only one possible orientation and electrical connection to trainline flanges is possible. The flanges include contact pins in inserts coupled to the flanges by sleeves. The outer surface of the inserts and the inner surface of the sleeves are keyed to allow only a single orientation of the inserts relative to the sleeves. The outer surface of the sleeves is shaped to allow only a single orientation of the sleeves relative to the flanges, thus ensuring that the proper electrical connection is made when the junction box is installed.

Abstract: Methods and apparatus for detection and notification of pressure waves are described herein. A lighting unit (100) may include one or more light sources (104) such as LEDs, a pressure wave sensor (106), a communication interface (108), and a controller (102) operably coupled with the one or more LEDs, the pressure wave sensor, and the communication interface. In various embodiments, the controller may be configured to receive a signal from the pressure wave sensor, the signal representative of one or more pressure waves detected by the pressure wave sensor. The controller may be configured to determine, based on the signal received from the pressure wave sensor, that the detected one or more pressure waves satisfy a predetermined criterion. The controller may be configured to transmit, to one or more remote lighting units via the communication interface, notification that the predetermined criterion has been satisfied.

Abstract: Disclosed is a lighting fixture (200) with a separately controllable set of LED-based light sources (102) configurable to create both downlighting and wall-washing lighting effects. To create the desired wall-washing effects, the intensity and angle of light sources in the lighting fixture are adjusted to individually illuminate different portions of the wall of surface. One set of LED-based light sources positioned along the edge of the ceiling tile is configured to emit a low intensity light beam toward the upper portion of the wall surface adjacent the ceiling. Another set of LED-based light sources emits a higher intensity light beam toward an intermediate portion of the wall surface. Another set of LED-based light sources emits an even higher intensity light beam toward the bottom portion of the wall surface.

Abstract: In various embodiments, one or more signals indicative of a shape formed by a flexible lighting strip (100) may be obtained, e.g., from one or more sensors (110) secured to the flexible lighting strip. One or more deformations in the flexible lighting strip may be detected based on the one or more signals. One or more light sources (102) may be selectively energized based on the one or more detected deformations. In some embodiments, one or more light sources contained in a first logical partition of the flexible lighting strip bound by at least one deformation may be energized to emit light having a first property. One or more light sources contained in a second logical partition of the flexible lighting strip separated from the first logical partition by at least one deformation may be energized to emit light having a second property different than the first property.

The lighting unit includes: a serial data input (121) receiving serial input data including at least first lighting data; first and second demultiplexed serial data outputs (123, 125); one or more individually addressable light sources (222, 322); one or more lighting drivers (250, 460, 650) receiving the first lighting data and in response thereto driving the individually addressable light source(s) to emit light; and a demultiplexer (124, 224, 324, 624). The demultiplexer demultiplexes at least a portion of the serial input data into first and second serial output data, and supplies the first serial output data to the first demultiplexed serial data output to be output from the first lighting unit, and the second serial output data to the second demultiplexed serial data output to be output from the first lighting unit.

Abstract: A 3D video system transfers video data from a video source device (40) to a destination device (50). The destination device has a destination depth processor (52) for providing destination depth data. The source device provides depth filtering data including filter location data, the depth filtering data representing a processing condition for processing the destination depth data in a filter area of the video indicated by the filter location data. The destination depth processor (52) is arranged for processing, in dependence on the depth filtering data, the destination depth data in an area of the video indicated by the filter location data. The depth filtering data enables the rendering process to improve the quality of the depth data.

Abstract: Systems, methods, apparatus (e.g., mobile computing devices), and computer-readable media are described herein for lighting control. In various embodiments, a mobile computing device may receive input indicative of a desired lighting property adjustment for a lighting effect sensed by a light sensor of the mobile computing device. The mobile computing device may identify one or more LED-based lighting units that contribute to the sensed lighting effect. The mobile computing device may then generate, for wireless transmission to the one or more contributing LED-based lighting units, an instruction configured to cause at least some of the one or more contributing LED-based lighting units to implement the desired lighting property adjustment. In various embodiments, one or more user inputs of the mobile computing device may be selectively enabled, based on a detected lighting context, to receive the input indicative of a desired lighting property adjustment.

Abstract: A hybrid transmission/auto-conversion 3D format and scheme for transmission of 3D data towards various types of 3D displays is described. In the decoder (20) a stereo-to-depth convertor (24) generates a depth map. In the 3D video signal additional depth information called depth helper data (DH-bitstr) is sparsely transmitted both in time (partial depths in time) and/or spatially (partial depth within the frames). A depth switcher (25) selects the partial depths based on an explicit or implicit mechanism for indicating when these are to be used or when the depths must be automatically generated locally. Advantageously disturbing depth errors due to said stereo-to-depth convertor are reduced by the depth helper data.

A radar circuit (140; 240; 340A; 340B; 440) may be electrically coupled to conductive wiring (25; 125; 225; 325; 425) of the LED-based lighting unit that at least selectively powers the radar circuit and at least selectively powers the LEDs. In some implementations, an antenna coupled to the radar circuit may be formed from the conductive wiring and optionally at least partially isolated from any current flowing through the LEDs.

Abstract: Three dimensional [3D] image data and auxiliary graphical data are combined for rendering on a 3D display (30) by detecting depth values occurring in the 3D image data, and setting auxiliary depth values for the auxiliary graphical data (31) adaptively in dependence of the detected depth values. The 3D image data and the auxiliary graphical data at the auxiliary depth value are combined based on the depth values of the 3D image data. First an area of attention (32) in the 3D image data is detected. A depth pattern for the area of attention is determined, and the auxiliary depth values are set in dependence of the depth pattern.
