摘要： A message board lighting fixture has semiconductor based lighting elements for illumination and an integrated electronic message board display for displaying content to occupants of a transit vehicle or other area. The lighting fixture may include a concave fixture frame having a reflective interior, with lighting elements positioned along the length of the frame to provide area illumination. The electronic display may be mounted on a projecting frame substantially centrally within the cavity of the concave fixture frame, and may be augmented with additional semiconductor based lighting elements for backlighting. A detachable lens cover may have a diffusive portion and a separate transparent region over the electronic display area.

摘要： A vehicle headlight and control system for a bus or large vehicle includes a headlight fixture with a center or low beam light source and side illumination light source operated independently. The side illumination light source may be activated when the vehicle is turning, as detected by the vehicle speed and steering shaft turn angle, to provide supplemental illumination. Both right and left side illumination sources may be provided, and may comprise LED light elements. The system may also include an audible sound generator to alert pedestrians when the vehicle is turning.

摘要： A computer-implemented process, system, and computer-readable storage medium having stored thereon, program code and instructions for 3-D triangulation-based image acquisition of a contoured surface/object-of-interest under observation by at least one camera, by projecting onto the surface-of-interest a multi-frequency pattern comprising a plurality of pixels representing at least a first and second superimposed sinusoid projected simultaneously, each of the sinusoids represented by the pixels having a unique temporal frequency and each of the pixels projected to satisfy I n p = A p + ∑ k = 1 K  B k p  cos  ( 2  π   f k  y p + 2  π   kn N ) Eq .  ( 1.1 ) where Inp is the intensity of a pixel in the projector for nth projected image in a particular instant in time; K is an integer representing the number of component sinusoids (e.g., K=2 for a dual-frequency sinusoid pattern, K=3 for a triple-frequency sinusoid, and so on), each component sinusoid having a distinct temporal frequency, where K is less than or equal to (N+1)/2. Images then captured by the camera are defined according to: I n c = A c + ∑ k = 1 K  B k c  cos  ( 2  π   f k  y p + 2  π   kn N ) + η Eq .  ( 1.2 ) To obtain phase terms from the pixels projected in accordance with Eq. 1.2, for each k: 2  π   f k  y p = arctan ( ∑ n = 0 N - 1  I n c × cos  ( 2  π   kn N ) ∑ n = 0 N - 1  I n c × sin  ( 2  π   kn N ) ) .

摘要： A control network comprises multiple master nodes and multiple slave nodes, connected together in a loop configuration by at least one fiber optic cable. The master nodes share concurrent control over the network nodes by time multiplexing or other techniques. The control network may include two fiber optic rings which carry the same data simultaneously in opposite directions around the loop. A polling scheme may be used by the master nodes such that only one node transmits at a given time in both directions around the loop. The receiving node(s) propagate the transmissions and select between the transmissions based on time, error rate, or other factors. A hierarchical control network may be constructed with upper tier and lower tier fiber optic rings. Multiple master nodes may be used at any level of the ring, and some or all of the rings may include two fiber optics for bidirectional, redundant communication within the network.
