Abstract: A system is for a plurality of different electric load types. The system includes a plurality of sensors structured to sense a voltage signal and a current signal for each of the different electric loads; and a processor. The processor acquires a voltage and current waveform from the sensors for a corresponding one of the different electric load types; calculates a power or current RMS profile of the waveform; quantizes the power or current RMS profile into a set of quantized state-values; evaluates a state-duration for each of the quantized state-values; evaluates a plurality of state-types based on the power or current RMS profile and the quantized state-values; generates a state-sequence that describes a corresponding finite state machine model of a generalized load start-up or transient profile for the corresponding electric load type; and identifies the corresponding electric load type.

Abstract: A dynamic stochastic optimal power flow (DSOPF) control system is described for performing multi-objective optimal control capability in complex electrical power systems. The DSOPF system and method replaces the traditional adaptive critic designs (ACDs) and secondary voltage control, and provides a coordinated AC power flow control solution to the smart grid operation in an environment with high short-term uncertainty and variability. The DSOPF system and method is used to provide nonlinear optimal control, where the control objective is explicitly formulated to incorporate power system economy, stability and security considerations. The system and method dynamically drives a power system to its optimal operating point by continuously adjusting the steady-state set points sent by a traditional optimal power flow algorithm.

Abstract: A series of signal processing features incorporated into its design that is both functional and decorative, to enhance convenience and performance among vocalists. A hollow, cylinder shaped body is oriented lie a conventional microphone, featuring a cardioid pickup pattern and a dynamic diaphragm, as well as a three-pin/XLR connector, a grill, and an integral pop filter. A transmitter handling the conversion of the audio signal into a radio signal and broadcasts it through an antenna, is built into the handle of the microphone, resulting in a wireless microphone that is slightly larger than a standard wired microphone. The microphone also has a shock-absorption system that reduces noise while the microphone is being handled buy the vocalist during a performance.

Abstract: A method for determining an image of a patterned object formed by a polychromatic lithographic projection system having a laser radiation source of a finite spectral bandwidth and a lens for imaging the patterned object to an image plane within a resist layer. The method comprises providing patterns for the object, a spectrum of the radiation source to be used in the lithographic projection system, an intensity and polarization distribution of the radiation source, and a lens impulse response in the spatial domain or in the spatial frequency domain of the image. The method then includes forming a polychromatic 4D bilinear vector kernel comprising a partially coherent polychromatic joint response between pairs of points in the spatial domain or in the spatial frequency domain, determining the dominant polychromatic 2D kernels of the polychromatic 4D bilinear vector kernel, and determining the image of the patterned object from convolutions of the object patterns with the dominant polychromatic 2D kernels.

Abstract: A saddle cloth for equestrian use to be applied to a horse prior to application of the saddle has zones adapted to lie beneath the saddle panels at respective sides of the horse. Each zone includes within a pocket, a separate air bag at least in a forward and a rearward part of the zone such that each air bag serves to apply a relatively even pressure to the back of the horse. Each air bag is substantially flat and is filled within its interior with a resiliently compressible open cell foam and air sealed within the bag is substantially at atmospheric pressure.
