Abstract: A light emitting diode (LED) system implements a power management technique. The LED system includes a plurality of LED drivers connected in series, each LED driver configured to regulate the current flowing through a corresponding subset of a plurality of LED strings. Each LED driver determines the tail voltages of the one or more LED strings of the corresponding subset. Each LED driver, except for the first LED driver in the series, also receives a voltage representative of the minimum tail voltage of the other subsets regulated by the upstream LED drivers. Each LED driver then provides the lowest of the voltage received from the upstream LED driver and the one or more tail voltages of the corresponding subset to the downstream LED driver. In this manner a voltage representative of the minimum tail voltage of the plurality of LED strings is cascaded through the series. A feedback controller monitors the minimum tail voltage represented by this cascaded voltage and accordingly adjusts an output voltage provided to the head ends of the plurality of LED strings.

Abstract: Disclosed are example open channel detection techniques at a light emitting diode (LED) driver of an LED system. The LED driver does not enable its LED channels before normal operation so as to inhibit current flow through the LED channels during start-up. While the LED channels are disabled, the LED driver compares the voltages at the LED channel inputs with a predetermined voltage to determine whether an operational LED string of an associated LED panel is connected to the LED channel. In the event that an LED channel is determined to be an “open” channel, the LED driver further disables the LED channel for the following normal operational mode. Otherwise, if the LED channel is determined to be connected to an operational LED string, the LED driver enables the LED channel for the normal operational mode, during which the LED channel can be selectively activated for light output subject to display data for the LED panel.

Abstract: A distributed collaborative computer system is provided that comprises a plurality of server computers interconnected via a high-speed link. Client computers can connect to any available server computer and start or join a conference hosted on either the server computer to which the client computer is connected or any other server in the system. As a result, the system and method of the present invention is easily scalable to support an arbitrary number of participants to a conference by merely adding the appropriate number of server computers to the system. In addition, by replicating the conference information on more than one server computer, the single point of failure limitation is eliminated. In fact, if a server hosting or participating in a conference malfunctions, the failure is detected by other server computers and the client computer is able to reconnect to the conference through a new server computer.

Abstract: A flow of liquids is carried out on a microscale utilizing surface effects to guide the liquid on flow paths to maintain laminar flow. No sidewall confining structure is required, minimizing resistance to flow and allowing laminar flow to be maintained at high flow rates. The guiding structure has flow guiding stripes formed on one or both of facing base and cover surfaces which are wettable by a selected liquid to direct the liquid from a source location to a destination location. The regions adjacent to the guiding stripes on the base and cover surfaces are non-wettable. The smooth interface between the gas and liquid along the flowing stream allows gas-liquid reactions to take place as a function of diffusion across the interface without mixing of the gas and liquid. Liquid-liquid flows may also be guided with such structures.

Abstract: A copper bonding pad is directly supported by a copper via pad structure, the copper via pad structure having substantially the same geometry and dimensions as the copper bonding pad. The combination of the copper bonding pad and the copper via pad structure results in an increase in effective thickness of the copper bonding pad. Due to this effective increase in the bonding pad thickness, the bonding pad is more tolerant to the potential dishing problem caused by the CMP process. Additional metal pad structures and via pad structures are used below the bonding pad. The additional metal pad structures and via pad structures comprise alternating segments of interconnect metal and dielectric fillers, and alternating segments of via metal and dielectric fillers, respectively. The alternating segments of interconnect metal and dielectric fillers and the alternating segments of via metal and dielectric fillers prevent or reduce the potential dishing problem that otherwise exists in damascene and CMP processing. The alternating segments of interconnect metal and dielectric fillers and the alternating segments of via metal and dielectric fillers are arranged such that there are a number of columns of solid metal support under the bonding pad. The columns of solid metal support significantly improve the poor mechanical support otherwise provided by the low dielectric constant materials that are presently used in fabrication of modern copper integrated circuits. The columns of solid metal support also improve thermal conductivity of the bonding pad.

Abstract: A dispersion mitigating interleaver assembly has a first unbalanced Mach-Zehnder interferometer (MZI) assembly which includes first and second output ports and which has first transmission vs. wavelength curve and a first dispersion vs. wavelength curve. The dispersion mitigating interleaver assembly also includes a second unbalanced MZI assembly which has a second transmission vs. wavelength curve and a second dispersion vs. wavelength curve. The second unbalanced MZI assembly receives an output from one of the first and second output ports of the first unbalanced MZI assembly. The second transmission vs. wavelength curve is substantially the same as the first transmission vs. wavelength curve and the second dispersion vs. wavelength curve is substantially opposite with respect to the first dispersion vs. wavelength curve, such that dispersion is substantially cancelled by the cooperation of the first and second unbalanced MZI assemblies.
