摘要:
A solid-state lamp using a light-emitting diode (LED) as a light source is described. In some embodiments, a segmented driver allows for greater flexibility with the optical and thermal design of the solid-state lamp.

A method, apparatus and computer program product for performing dynamic Voice Over Internet Protocol (VOIP) endpoint mapping is presented. At least one on net endpoint of a VOIP call is determined. An endpoint data structure is used to store, for each on net endpoint of the call, a key and at least one of an Internet Protocol (IP) address of the end point, a phone number associated with the endpoint, and/or a display name associated with the endpoint. The endpoint data structure is used to correlate call legs across a network. Heuristics of the VOIP call are determined, the heuristics including information relating to the main source call leg and the main destination call leg.
摘要:
A phosphor deposition process and apparatus that enables an efficient, consistent, and flexible white light LED light engine by spraying a conformal coating of phosphor matrix onto an array of LEDs to achieve high color uniformity, consistency, and efficiency. A predetermined ratio of one or more phosphor powders are mixed with a support matrix (preferably silicone), the types and amounts of which are calculated to provide a predetermined spectral output. A low-viscosity carrier is introduced into the phosphor matrix to allow for further processing and deposition. The phosphor matrix and carrier mixture is atomized and sprayed in one or more uniform layers onto one or more LED devices. Computerized control, movable stages, and in-process spectral monitoring are incorporated to provide rapid and accurate processing of LED devices.

A light fixture for location adjacent to a surface. The fixture includes a framework that permits flow therethrough. The framework has a plurality of sides. The fixture includes a plurality of light devices extending along the plurality of sides of the framework. Each pair of adjacent sides meet at a corner. The fixture includes a plurality of cove pieces extending adjacent to the plurality of light devices along the plurality of sides of the framework. Each cove piece terminates in the vicinity of associated corners of the framework. The fixture includes a plurality of corner pieces located at the corners of the framework. Each corner piece overlaps at least a portion of each of two cove pieces terminating in the vicinity of associated corner of the framework.

Apparatus and methods for wire-tying one or more objects. A wire accumulating and feeding mechanism feeds the wire axially through the hollow axle of an accumulator drum and then out to a drive wheel. The wire is wrapped around the periphery of the drum to accumulate the wire during tensioning. A wire gripping mechanism is a simple, economical device including a gripper block having a wire receptacle formed therein, an opposing wall positioned proximate the wire receptacle, and in one embodiment a tapered gap formed in the gripper block proximate the wire receptacle and opposite from the opposing wall, and a gripper disc mounts in a gripper release lever constrained to move within the tapered gap and frictionally engageable with the length of wire disposed within the wire receptacle, the gripper disc being driven into the tapered gap by frictional engagement with the length of wire and pinching the length of wire against the opposing wall when the drive motor is operated in the tension direction. In an alternative embodiment the gripper release lever pinches the wire against the gripping wall. In another embodiment, an apparatus includes a track assembly including multiple modular segments forming a corner of the track. In yet another aspect, a twisting assembly includes a twist motor coupled to a rotatable twist axle having a plurality of cams attached thereto, the primary functions of the twisting assembly being cam-actuated.

Illumination assemblies, components, and related methods are described. An illumination assembly can include at least one solid state light-emitting device, and at least one light guide including a light homogenization region configured to receive light emitted by the solid state light-emitting device and including a light output boundary. The light homogenization region substantially uniformly distributes light outputted over the light output boundary. A wavelength converting material can be disposed within at least a portion of the light homogenization region. In some assemblies, a light extraction region can be configured to receive light from the light output boundary of the light homogenization region, and can have a length along which received light propagates and an emission surface through which light is emitted. The light extraction region can include a wavelength converting material disposed within at least a portion of the light extraction region.
