摘要:
View-upload decoupled (“VUD”) peer-to-peer (P2P) video distribution is provided, in which each peer is assigned to one or more channels to upload, with the assignments made independent of what the peer is viewing. For each assigned channel, the peer distributes (that is, uploads) the channel. This effectively creates semi-permanent distribution swarms for each channel, which are formed by peers responsible for uploading that channel. This can minimize problems associated with channel churn because peers may remain in their assigned distribution groups even if they switch channels. To minimize cross-channel overhead associated with VUD P2P video distribution, substream swarming, in which a peer in a distribution swarm only downloads a small portion of the video stream, called a substream, and uploads the substream to multiple viewers, may be provided. To minimize video streaming quality degradation that may occur during a reconfiguration transient period upon sudden and large increases in video download demands for some channel, VUD P2P video distribution may be integrated with tradition ISO P2P video distribution (which is self-adaptive to the sudden increases in channel popularity).

Optocoupler devices and methods for making and using such devices are described. The optocoupler devices contain a light emitting component (a light emitting diode [LED]) and a light receiving component (a phototransistor [PT]) device that are embedded within the substrate, rather than being attached to the surface of the pre-molded substrate. Such a configuration eliminates the bond wires that are often used when the LED and PT are attached on the substrate, improves the electrical performance, and allows the final optocoupler package to be made smaller and thinner. Other embodiments are described.

A method and system for communication between mobile stations in a wireless relay enhanced cellular communication system. One implementation involves providing a communication resource allocation for peer-to-peer (P2P) communication between a pair of mobile stations during a P2P enhanced time frame wherein one mobile station serves a role as a transparent relay station (MRS) and another mobile station serves a role as a peer mobile station in the pair; and delivering resource allocation information comprising communication periods and frequency subcarriers to the pair of mobile stations, for the mobile station pair to conduct P2P communication therebetween in the P2P enhanced time frame.
摘要:
A laser illumination beam generation system including a laser diode (LD) for producing a laser beam in response to a diode current supplied thereto, wherein the laser beam has a central characteristic wavelength. Diode current drive circuitry generates the diode current and supplies the same to the VLD. A high frequency modulation (HFM) circuitry modulates the diode current supplied to the laser diode, so as to produce a spectral side-band components about the central characteristic wavelength, and thereby reduces the coherence of the laser illumination beam as well as its coherence length. An optical multiplexing (OMUX) device receives the laser beam as an input beam and generates multiple laser beams therefrom and recombines the multiple laser beams so as to produce a composite output laser illumination beam having reduce coherence.
摘要:
A method of driving a plurality of visible and invisible laser diodes so as to produce an illumination beam having a dynamically managed ratio of visible to invisible (IR) spectral energy/power during object illumination and imaging operations. The method involves supplying a plurality of visible laser and invisible laser diodes with a predetermined/default values of diode drive currents so as to illuminate the object with a spectral mixture of illumination during object illumination and imaging operations. One or more digital images of the illuminated object are captured and the image contrast quality thereof is measured, in real-time, so as to generate feedback or control data. This feedback or control data is used to dynamically generate the necessary values for the adjusted diode drive currents that are used to drive the visible and invisible laser diodes and produce an illumination beam having a dynamically managed ratio of visible to invisible (IR) spectral energy/power required to produce images of sufficient image contrast to ensure satisfactory image processing, while minimizing visual brightness to humans, at a POS station during object illumination and imaging operations.
