Abstract:
Methods and apparatus are arranged to increase thermal efficiency, reduce waste water treatment, reduce net usage of fresh water, and improve operational reliability during direct hydrothermal upgrading of carbonaceous materials, including low-rank coals. Drain water collected from the hydrothermal upgrading system is passed through a reboiler system to generate steam which can be returned to the hydrothermal processor system for use therein.
Abstract:
A lighting system including a light-emitting diode cradle securing at least one light-emitting diode and a modular unit comprising an arcuate portion, the arcuate portion comprising at least one diffusive reflective surface adapted to receive and reflect light from the at least one light-emitting diode. The lighting system further includes a diffusive transmissive element adapted to receive light reflected by the diffusive reflective surface and provide diffused light to an area requiring illumination.
Abstract:
An analog-to-digital conversion system has an analog-to-digital converter (300) and a digital-filter system (100). The digital-filter system (100) is connected to the output of the analog-to-digital converter (300). A processor (310) is connected to the output of the digital-filter system (100) so that the processor (310) transparently receives filtered sample data in the native format of the analog-to-digital converter (300). An FIR filter circuit (130) in the digital-filter system (100) is connected to receive data from, and output filtered data to, a sample capture and data-type conversion circuit (120) connected between the analog-to-digital converter (300) and the processor (310). A configuration and control-register circuit (110) is connected to the circuit for sample collection and data-type conversion (120), and to the FIR filter circuit (130), for selectively controlling the operation of the digital filter system (100) according to parameters for data conversion and filter operation passed to the configuration and control-register circuit (110) over a serial interface.

Abstract:
We disclose a CIC digital filter having an arbitrary-integer decimation rate. The filter has a shifter (110) connected to its input. The shifter (110) receives a shift control input, where the shift control input is pre-computed as equal to the integer portion of 2 raised to the base-2 logarithm of the gain of the CIC filter. There is a multiplier (100) connected between the input and the shifter (110). In other embodiments, the multiplier (100) could be connected between the input and the shifter (110). Sequentially-connected integrator (130) functions are connected to the shifter (110) or multiplier (100); a decimation function receives input from the integrator (130) functions; and sequentially-connected differentiator (150) functions receive input from the decimation function. The decimation function has a selectable rate equal to any integer between 1 and a number equal to the predetermined maximum decimation value. The multiplier (100) is configured to compute the product of each input data sample by a correction factor; the correction factor being pre-computed as equal to the fractional portion of 2 raised to the base-2 logarithm of the gain of the CIC filter, so as to correct the gain of the CIC filter for decimation values not a power of 2.
