Abstract: Different subscriber units (14) transmit different burst signals to a base station (12) on a common frequency to which a base station demodulator (64) is already synchronized. The base station (12) transmits constant values .alpha. and .eta., where .alpha. is multiplied by a base station reference frequency to achieve a base station transmitting frequency, and .eta. is multiplied by the reference frequency to achieve the base station (12) receiving frequency. A subscriber unit (14) synchronizes to the base station transmitting frequency. As a result of the synchronization process, the subscriber unit (14) determines a value .mu., which, when multiplied by a subscriber unit reference frequency, achieves the subscriber unit synchronization frequency. The subscriber unit then determines a value .gamma., which is proportional to .eta. and .beta. and inversely proportional to .alpha.. The subscriber unit reference frequency is multiplied by .gamma.

Abstract: A method (30) is provided for the detection and analysis of anomalies (32) in a road surface (36). An image (34) of the road surface (36) is obtained (82) wherein traffic control markings (76) are masked (88). The image (34) is filtered (90) and a pixel map (92) is produced (98). The pixel map (92) is partitioned (112) into a multiplicity of subimages (108). For each subimage (108), anomaly parameters are identified (120) and a status characteristic is determined (124) and assigned (136). A subimage map (138) is produced (142) depicting the subimages (108) and their status characteristics. A determination (156) is made as to which subimages (108) contain anomalies (32). Anomaly-containing subimages (108) are grouped (158) into anomalous objects (152). For each anomalous object (152), an object type (162) is determined (160) and assigned (164). An object map (154) is then produced (166) depicting the anomalous objects (152).

Abstract: A vibration isolation system (20) reduces vibrations produced by an operating electric motor (22). A motor retainer ring (24) fits into a motor retaining ring isolator (40) which is placed into a mounting surface opening (52) such that protrusions (48) contact a mounting surface (50). An upper motor cover (54) and a lower motor cover (60) are positioned to surround motor (22) while protruding ridges (62) space the interior surface away from motor (22). Fasteners (32) fit through retainer mounting holes (30) and attach to threaded holes (38) such that protrusions (58) of the upper motor cover (54) contact the mounting surface (50).

The inductor (20, 20') includes at least one coil (62, 78) arranged so that its axis (58) is parallel to the substrate (22).

Abstract: A distributed amplifier (10) configured to amplify an input signal (20) is presented. Within the amplifier (10), a first input phase-shift element (40) shifts the input signal (20) into a first shifted input signal (56). A first active element (18'), coupled to the first input phase-shift element (40), amplifies the first shifted input signal (56) into a first amplified signal (58). A second phase-shift element (42), coupled to the first input phase-shift element (40), shifts the first shifted input signal (56) into a second shifted input signal (62). A second active element (18"), coupled to the second phase-shift element (42), amplifies the second shifted input signal (62) into a second amplified signal (64). A first output phase-shift element (44), coupled to the first active element (18'), shifts the first amplified signal (58) into a first shifted amplified signal (60).

Abstract: A digital communication system (20) communicates using a polar amplitude phase shift keyed (P-APSK) phase point constellation (70, 70'). Pragmatic encoding and puncturing is accommodated. The pragmatic encoding uses the P-APSK constellation (70, 70') to simultaneously communicate both encoded and uncoded information bits. The P-APSK constellation (70, 70') has an even number of phase point rings (74, 76) and equal numbers of phase points (72) in pairs of the rings (74, 76). Encoded bits specify secondary modulation and uncoded bits specify primary modulation. The constellation (70, 70') is configured so that secondary modulation sub-constellations (78) include four phase points (72) arranged so that two of the four phase points (72) exhibit two phase angles at one magnitude and the other two of the four phase points exhibit phase angles that are at another magnitude. The difference between the phase angles at different magnitudes within a secondary sub-constellation (78) is constant.

Abstract: A communication system (10) includes a rotationally invariant pragmatic trellis coded modulator (18) and demodulator (34). The modulator (18) partitions information bits (20) into primary (42) and secondary (44) data streams. The secondary data stream (44) is convolutionally encoded (70) then fed to the LSB of a phase mapper (76). The phase mapper (76) is arranged so that all pairs of adjacent phase data are generated from pairs of opposing polarity LSB inputs. The primary data stream (42) is differentially encoded through a dual channel differential encoder (50). The demodulator (34) convolutionally decodes (90) the secondary stream, then re-encodes (96) secondary stream estimates. The re-encoded secondary stream estimates are used to remove (102) the secondary modulation from phase value estimates. Adjusted phase value estimates are phase demodulated (104) and differentially decoded using a dual channel differential decoder (106).

Abstract: A system (10) controls the dispensing of valuable commodities, such as beers. The system (10) includes a controller (36), sensors (26, 34), and solenoid-activated valves (24). The dispensing of a commodity begins when an operator identifies himself or herself to the controller (36) after selecting a commodity and quantity. A record of this transaction is recorded in a memory (40) of the controller (36). The controller (36) continues dispensing the selected commodity, determines when the selected quantity has been dispensed, then automatically ceases dispensing the commodity. Reports (178) are generated summarizing dispensing transactions. A variety of operational parameters may be established by a manager. Parameters relevant to the preservation and flow of the commodity, such as temperature and pressure, are monitored, and warnings annunciated (164, 170) if out-of-range conditions are detected.

A controller receives the air and sample temperature signals (54, 60) and controls the heater (26) in response to the signals.
