Abstract: Disclosed herein are exterior architectural fixtures employing LED-based light sources that are capable of projecting light over long distances and providing a wide variety of lighting effects with high lumen output. These lighting fixtures have improved heat dissipation properties and are particularly suitable for large-scale façade washing and for illuminating large architectural structures, such as skyscrapers, casinos, and retail establishments, integrating efficient and compact power supply and control components for driving high-intensity LEDs to achieve a vast variety of lighting effects on a large scale.

Abstract: A reference time distribution system and method use a data transmission network having a plurality of nodes to distribute the House Sync signal. A network-wide time signal is generated using a reference time generator, and the network-wide time signal is then distributed over the network to the plurality of nodes. At each node, the network-wide time signal is converted to a local synchronization signal for use in performing synchronization of the timing of each node. Either network-inherent timing and/or additional time signaling is used to provide the nodes attached to this network with a network-wide notion of time. The time information is converted locally into synchronization signals or time information as required by a respective application. When data is transported over the network, delay compensation is performed to simultaneously output different data streams that have been synchronously input into the network, regardless of the data path.

Abstract: A device for gluing a tail cant of a roll or log of wound web material, includes a support for the roll, a dispenser of glue, a movable blade on which a gluing application edge is provided, the blade (5) being oriented parallel to the roll-longitudinal axis (CD). The glue application edge (10) of the blade (5) has interrupted glue application surface.

Abstract: A TIR collimator for an LED light source includes a body portion having a reflective surface, wherein the reflective surface includes a plurality of segments. Respective segments of the reflective surface have corresponding cross-sectional profiles defined by different low-order polynomial functions, such that the overall cross-sectional profile of the reflective surface constitutes a spline, i.e., a piecewise polynomial function. The respective segments are configured to achieve substantial collimation of the output light. In one example, the cross-sectional profiles of adjacent segments of the reflective surface are defined by different low-order polynomials. Additionally, two or more adjacent segments may have respective cross-sectional profiles which together are defined by a Bezier curve, so as to provide smooth transitions between adjacent segments of the spline reflective surface.

Abstract: A digitally-controlled oscillator comprises an input for the supply of a digital input word, an adder, a stable local oscillator and a delay circuit, comprising a delay stage with a number of serially-connected coarse delay elements and a fine delay stage with a number of serially-connected fine delay elements. The coarse delay stage and the fine delay stage are embodied such that the maximum total delay and the minimum total delay differ by at most one period of the cycle signal. The delay produced by the number of fine delay elements corresponds to the delay of one coarse delay element. Each coarse delay element and each fine delay element comprise their own controllable selector.

Abstract: A lamp housing assembly as provided which includes a lamp housing and a shield. The shield includes a first portion which extends into the cavity of the lamp housing and a second portion which extends out of the lamp housing. The first portion extends to a blocking end adapted to be positioned adjacent to a lamp disposed within the lamp housing cavity. The second portion includes an attachment end coupled to the lamp housing external of the lamp housing cavity.

Abstract: A method of determining a communications channel including detecting whether a host is in a system; if a host is detected, querying the host for a channel on which to communicate and switching a channel selection logic based on a result from the query; and if a host is not detected, determining a channel on which to communicate based on the number of devices on each channel.

Abstract: A housing for a device including a first surface having a connector disposed thereon, the connector configured to mechanically couple to an oppositely mated connector on a second surface of a second device. The first surface also has a set of surface features disposed thereon, the set of surface features configured to engage an oppositely mirroring set of surface features on the second surface. When the device is stacked with the second device, the connector and the set of surface features of the first surface interact with the oppositely mated connector and the oppositely mirroring set of surface features on the second surface, respectively, to prevent vertical separation and horizontal dislocation between the device and the second device.

Abstract: A data processing system includes a processor unit (CPU) connected over a CPU bus to a plurality of memory components, but is not connected to any input-output (I/O) component of the system. The system I/O component(s) connect to the memories over an I/O bus. A method and apparatus is disclosed for selecting one of the memories to be used for communications between the processor unit and the I/O components. Also, a method for determining which I/O components are in the system.
