Abstract: The invention is a method and system for compressing a current value into a minimum number of bits for transmission from a compressor to a decompressor. A method in accordance with the invention includes maintaining a series of at least one previous value at the compressor, each previous value having different k least significant bits and which have been transmitted to the decompressor; determining a value of k representing a smallest number of bits which allows successful decompression of the current value at the decompressor using as a reference value any value in the series of at least one previous value; and transmitting the current value from the compressor to the decompressor in compressed form with the k least significant bits of the current value.

Abstract: A gas separation device (10) includes an inner conduit (14), and a concentri c outer conduit (18). An electrically conductive filter media (60), preferably a carbon fiber composite molecular sieve, is provided in the annular space between the inner conduit and the outer conduit. Gas flows through the inner conduit and the annular space between the inner conduit and the outer condui t, so as to contact the filter media. The filter media preferentially adsorbs a t least one constituent of the gas stream. The filter media is regenerated by causing an electric current to flow through the filter media. The inner conduit and outer conduit are preferably electrically conductive whereby the regeneration of the filter media can be electrically stimulated. The inventi on is particularly useful for the removal of CO2 from the exhaust gases of foss il- fueled power plants.

Filed: 2003-12-30
Granted: 2010-02-09
Abstract: An improved external rotor motor, suitable for driving a cooling fan, has a structure which facilitates automated assembly with proper angular registration of its components. The motor has an external rotor (42) with a central shaft (40) which is rotatably supported inside a bearing support tube (38) having a tapered outer surface (98) formed with a circumferential stop (100) and a plurality of longitudinal guide grooves (102). An inner stator structure (22) is located radially between the bearing support tube (38) and the rotor (42). The inner stator has an internal recess (36) containing a securing ring or disk (20) with inwardly extending tabs (34). During assembly of the inner stator onto the bearing support tube (38), the tabs of the securing ring slide in the guide grooves (102), then bend to form barbs (34') which engage into the outer surface (98) of the bearing support tube, thereby securing the stator (22) on the bearing support tube in a precisely predefined angular orientation. The circumferential stop (100) assures insertion of the bearing support tube to the correct depth.
