Exemplary apparatus, method and system embodiments provide for separately and independently sourcing current to a series of light emitting diodes of a plurality of series of light-emitting diodes. An exemplary apparatus comprises a power converter which generates a current, a first multiplexer, and a controller. The controller provides for sequential and separate switching of the current through the first multiplexer to each of the series of light-emitting diodes for a corresponding period of time. An average current provided by the power converter is determined as substantially equal to a sum of the corresponding currents through the plurality of series of light-emitting diodes. A total period for switching current to all of the series of light-emitting diodes is also determined. A corresponding time period for switching current to a selected corresponding series of light-emitting diodes is substantially equal to a proportion of the total period determined as a ratio of the corresponding current for the selected corresponding series of light-emitting diodes to the average current provided by the power converter.

Embodiments of the present invention pertain to substrate processing equipment and methods incorporating light emitting diodes (LEDs) for thermally processing substrates. Such light sources offer a variety of advantages including higher efficiency and more rapid response times. Pulse widths are selectable down to under a millisecond but can be for long pulses up to and exceeding a second. LEDs are preferable to tungsten-halogen lamps even in circumstances that allow longer processing times, since LEDs produce light with greater than 50% efficiency and tungsten-halogen lamps operate with less than 5% efficiency.

A method and a system for self-regulating wireless power transmitted to a wireless power receiver (WPR) are provided. An auto-tuning network is operably coupled within the WPR. The auto-tuning network includes an impedance network that dynamically increases, decreases, or maintains an amount of the received wirelessly transmitted power by detecting changes in a rectifier load disposed in the WPR and / or in a rectifier output voltage in the WPR. The auto-tuning network self-regulates the wireless power received from a wireless power transmitter (WPT) obviating the need for conventional communication messages. The WPT is hence free from a modulator / demodulator block and an out-of-band communication block and operates over a limited operating range to enable a simpler design for passing electromagnetic compliance regulations. The WPR implements a receiver-maximum-power-signature algorithm for enabling the WPT to detect unsupported receivers, configure its operating point and range, and terminate power transmission when not needed by the WPR.

An integrated optimization and control technique integrates an optimization procedure, such as a linear or quadratic programming optimization procedure, with advanced control, such as model predictive control, within a process plant in which the number of control and auxiliary variables can be greater than the number of manipulated variables within the process plant. The technique first determines a step response matrix defining the correlation between changes in the manipulated variables and each of the process variables that are used during optimization. A subset of the control variables and auxiliary variables is then selected to be used as inputs to a model predictive control routine used to perform control during operation of the process and a square M by M control matrix to be used by the model predictive control routine is generated. Thereafter, during each scan of the process controller, the optimizer routine calculates the optimal operating target of each of the complete set of control and auxiliary variables and provides the determined target operating points for each of the selected subset of control and auxiliary variables to the model predictive control routine as inputs. The model predictive control routine determines changes in the manipulated variables for use in controlling the process from the target and measured values for each of the subset of the control and auxiliary variables and the M by M control matrix.

A digital STB having multiple decoders is capable of decoding multiple digital video streams simultaneously to minimize the time a subscriber waits before a new channel is tuned and displayed. The STB incorporates a channel look-ahead capability in which one or more digital tuners tune to and decode a next video channel based upon information taken from a subscriber's usage history and information obtained from average subscriber behavior. STB software performs a channel prediction to setup spare tuning and decoding resources to tune to and decode a potential channel the subscriber might select next. The STB can therefore anticipate the subscriber's request and provide a faster response time for channel tuning.

An architecture for quality-of-service (QoS) management creates a logical circuit-switched network within a packet network to support QoS-sensitive demands levied on the network. This QoS-managed network can serve to interwork, e.g., a PSTN with VoIP networks. The architecture can include a connection resource manager (CRM), which oversees bandwidth availability and demand admission / rejection on dynamically provisioned virtual trunk groups (VTGs) within the packet network, and a transport bandwidth controller (TBC). The VTGs serve to transport QoS-sensitive demands across the packet network. The TBC serves the CRM by providing an interface to routers and / or OAM systems of the packet network to size VTGs to meet QoS requirements. Media switches located at the packet network borders serve to mux / demux the demands into / from VTGs. CRMs and TBCs can be implemented as centralized, distributed, or hierarchical, and flat and aggregated variants of the architecture are supported. VTGs can be implemented using MPLS LSPs, VPNs, or source-based routing.

A subscriber profile access management system for a telecommunications service provider or telecommunications operator provides technical solutions to providing a single point of access to telecommunications subscriber profile information. As the products and services offered by the service provider grow, and given the many different access mechanisms through which a subscriber connects to services, the single point of access eliminates the inefficient proliferation of custom interfaces between the many support systems and applications which need access to subscriber profile information. The single point of access provides a universal and personalized access to telecommunications services. Access may be made to the subscriber profile regardless of the particular type of access mechanism (e.g., WiFi, or DSL access), while the personalized access allows services to be customized based upon static and dynamically maintained information in the subscriber profile.

A system for allocating resources which are anticipated to be available in an on-demand computing at some time in the future, wherein a producer trending agent (PTA) lists resources according to a trend prediction of resource availability in the past, a consumer trending agent (CTA) places bids for listed resources according to previous resource usage trends, and an arbitration system (REAS) matches the bids with the listings to determine if a match exists. If so, a binding contract for consumption of the matched listed resources is established. The PTA also produce tier-based dynamic incentive (TDI) schema which divides potential bidders into tiers, and offers additional resource incentives according to the tiers. Both PTA and CTA dynamically update their available / usage trends, listings and bids, over time.
