摘要： A conveyor construction includes a frame, a drive section stationarily mounted to the frame, and a tensioning section mounted for longitudinal movement relative to the frame. The drive and tensioning sections each include a spindle, and a belt is engaged with the spindles. The frame defines an upper support surface disposed below the upper run of the belt, and mating engagement structure is provided on the belt and the upper support surface for preventing lateral movement of the belt relative to the upper support surface. The drive and tensioning sections include spaced side members, each of which defines an inwardly opening cavity for receiving a bearing assembly for rotatably supporting the spindle. The bearing-receiving cavity faces the spindle, and each side member defines outer wall structure which engages and supports the belt outwardly of the spindle. The belt overlies the outer wall structure of each side member and the adjacent belt-engaging portion of the spindle, so as to seal the inwardly facing opening and prevent ingress of moisture or other contaminants into the bearing-receiving cavity. A drive and locking arrangement for imparting movement to the tensioning section and for selectively locking the tensioning section in position includes a pair of pinion carriers or retainer blocks mounted one to each side of the frame, with a drive pinion being rotatably supported by the retainer blocks. Each side member includes integrally formed gear teeth engageable with opposite ends of the drive pinion, and a drive pinion actuator is engaged with one side of the frame for imparting rotation to the drive pinion to extend and retract the tensioning section. A locking arrangement is interconnected with the opposite end of the drive pinion, and functions to selectively frictionally engage the drive pinion with one of the retainer blocks to prevent rotation of the drive pinion and to thereby maintain the tensioning section in a desired position relative to the frame.

摘要： A single-chip transceiver integrated circuit (100) has multiple on-chip circuits that implement receiver functions, transmitter functions, and audio processing functions. The IC (100) has interfaces (220, 240, 252, 270, 260, 245, 288, 290) which are situated among the on-chip circuits, and which couple one on-chip circuit to another. At least some of these on-chip interfaces (220, 240, 245, 252, 270) are configurable to couple an off-chip processing circuit to substitute for a corresponding on-chip circuit. In the preferred embodiment, the single-chip transceiver IC (100) supports radio configurations having off-chip versions of corresponding on-chip circuits for performing receiver front-end functions, synthesizer functions, reference oscillator functions, and audio processing functions.

摘要： A method for acquiring rapid automatic gain control (AGC) response in a narrow band receiver teaches opening the AGC loop (100), setting the gain control signal (106) amplitude of the AGC amplifier stage (104) to a known value, altering the gain control signal (106) amplitude over time, and monitoring the narrow band receiver for an output signal (112). Upon output signal (112) detection, halting alteration of the gain control signal (106) amplitude, closing the AGC loop (100) and commencing normal operation. A particular facet of this approach suggests detecting the output (112) with a varying gain detector (116,132) after the loop (100) is closed and before normal operations are commenced.

摘要： A method and arrangement for a fully synchronized, programmable frequency divider is disclosed that exhibits a near 50% duty cycle output signal independent of the divisor, whether even or odd, and that is suitable for use in a phase-locked loop (PLL) frequency synthesizer. As described in a first embodiment, the arrangement includes a data loader 31, a counter 32, a half-period detector 33, and a synchronizer 34. Next, a fast-locking, low-noise PLL frequency synthesizer is disclosed incorporating the fully synchronized, 50% duty cycle divider, and having a reference signal generator 71-72, a phase detector 73, a controlled oscillator 74-75, and the fully synchronized, programmable frequency divider 76. In a second embodiment, a fully synchronized programmable divider is described, including a data loader 31, a counter 32, a half-period detector 33', a synchronizer 34', and an additional block 82, a half-clock period detector. Synchronizer 34' is modified to include an additional block 84, an output logic circuit, which allows for an output signal duty cycle virtually equal to 50% for odd as well as even integer divisors.

摘要： A SONAD (110) control system (100) detects a received signal strength (RSSI) for a radio frequency (RF) signal (102), selects a threshold transfer function (400-404) in response thereto, generates a threshold control signal in response to the transfer function, and utilizes the threshold control signal to select the SONAD threshold value. During operation, the control system (100) decreases the attenuation of background noise levels for weak RF signals.

摘要： A conveyor construction including a frame having a pair of side rails with each side rail having a longitudinal T-shaped slot. A plurality of cross members are connected between the side rails and support a bed plate. An endless belt rides on the bed plate and is trained over an adjustable spindle assembly which is located at an end of the conveyor. The spindle assembly includes a spindle journalled between a pair of side members that are mounted for sliding movement in the T-slots of the respective side rails. A ratchet and pinion mechanism interconnects the conveyor frame with the spindle assembly and acts to move the spindle assembly longitudinally of the frame to tension the belt. A belt tracking mechanism is associated with each side of the spindle assembly and includes a cam member which is engaged with the respective side member of the spindle assembly. Individual rotation of the cam members serve to properly track the belt on the bed plate. To attach components to the conveyor frame, spring loaded nuts are slidably mounted in the T-slots of the side rails and the components are attached to the spring loaded nuts.

摘要： A method and arrangement for electronically bandswitching a radio (100) is described which includes at least a receiver (110, 111), a PLL (120), and a fully synchronized, programmable counter as a frequency divider (140) that is coupled between the receiver and the PLL. This fully synchronized divider (140) provides an output signal (143) at a lower frequency with minimal harmonic energy and improves the sideband noise performance as the divisor increases. When the radio also includes a transmitter (104), stepped attenuators (128, 132) are also included for adjusting the modulation of the PLL (120) when in the transmit mode.The PLL includes at least a reference signal generator (121, 122), a phase detector (124), and a voltage controlled oscillator (127) having an output (129) coupled, via a feedback path, to a second input (131) of the phase detector (124). The fully synchronized, programmable frequency divider includes at least a counter, a data loader, a half-period detector, and a synchronizer which are configured and arranged to provide an output signal (143) having a duty cycle, nearly equal to 50%, which is independent of a divisor and which simplifies the filtering requirements thereafter, thereby providing electronic bandswitching for the radio while exhibiting fast-locking and low-noise characteristics.
