Disclosed is a method and apparatus to continuously transmit high bandwidth, real-time data, on a communications network (e.g., wired, wireless, and a combination of wired and wireless segments). A control computing device uses user or application requirements to dynamically adjust the throughput of the system to match the bandwidth of the communications network being used, so that data latency is minimized. An operator can visualize the instantaneous characteristic of the link and, if necessary, make a tradeoff between the latency and resolution of the data to help maintain the real-time nature of the system and better utilize the available network resources. Automated control strategies have also been implemented into the system to enable dynamic adjustments of the system throughput to minimize latency while maximizing data resolution. Several applications have been cited in which latency minimization techniques can be employed for enhanced dynamic performance.

A resolution enhancement algorithm is trained on sample images to obtain a polynomial model mapping of low resolution image data to high resolution image data.

The mapping provides resolution enhancement which is superior to that of conventional image data interpolation techniques.

A method for load control in an electrical distribution system using energy usage profiles based on temporal measurements. A load control unit (10) installed at a customer site profiles equipment (E1-En) directly connected to the load control unit and remotely located equipment (RE1-REn) wirelessly connected to the load control unit using measurements of time rather than energy usage. This reduces the cost and complexity of the load control unit. Profiling is done for individual pieces of load controlled equipment rather than for the site as a whole. This improves data resolution. The load control unit controls the load only when the equipment is powered, and adaptively synchronizes load shedding during this time, so to improve local load control performance. Termination of a load control event results in gradual reduction in load shedding so to control the inrush of demand seen by the distribution system. Performance metrics related to the load control are provided to the utility such that complexity of the system is reduced through decreased computations.

A class D amplifier uses a summation of two or more PWM output stages to achieve an increased dynamic range and improved linearity for any given clock operating speed. The amplifier accepts a digital data stream as its input, such as from a compact disk, or other compatible media, at a data rate, Fa, that could be 44.1 kHz, 96 kHz, or any other rate appropriate for audio data. In the preferred embodiment, the input audio data resolution, N bits, would be split into two data samples, of J and K.Internal switching frequency, Fs, switches the PWM with an over sampling factor M, where Fs=M*Fa. The time resolution of the PWM is determined by a precision oscillator that operates at Fc=Fs*(max(J,K)-log2(M)+1).The J most significant bits would be routed to a power PWM stage operated at a DC voltage of VHI. The K least significant bits are routed to a finesse PWM stage operated at a DC voltage of VLO.The ratio of VLO to VHI will be appropriate for the ratio of K and J so the summation of the power PWM stage and the finesse PWM stage will provide the full range of N bits. This summation is accomplished with a low pass filter and time-division multiplexing of the two PWM stages.A micro controller (MCU) is used to apply a sample packet distribution algorithm to provide more resolution by reducing quantization noise in the audio band of interest. The MCU is also used to calibrate the VLO or VHI, or to calibrate the PWM timing of the two PWM stages to achieve appropriate performance.
