摘要： A sensor assembly for monitoring shocks and vibrations on sensitive devices is provided. The sensor assembly comprises a detector beam supported between a pair of support members. A detector weight is secured to the detector beam between the support members. The detector beam is fracturable in response to the application of a predetermined level of force. An electrical circuit may be coupled to the detector beam for monitoring electrical continuity and structural integrity of the detector beam. The detector beam provides passive monitoring as the detector beam will fracture irrespectively of the power state of the electrical circuit. One or more detector beams may be used to monitor forces along a variety of different axes.

摘要： A laser beam transmitting system is provided comprising at least one target, a laser detection module, an optical system, a rotary encoder, a dither zone memory, and a controller. The optical system is arranged to generate a reference laser beam selectively in one of a search mode and a target dither mode and to direct a laser beam reflected from the target to the laser detection module. The search mode is characterized by movement of the reference beam through a rotational arc defined about a central rotational axis and the target dither mode is characterized by movement of the reference beam through a selected discrete portion of the rotational arc. The rotary encoder is arranged to produce a rotary signal indicative of a rotary position of the reference beam relative to the rotational arc. The controller is programmed to identify a position of the at least one target based upon the reflected laser beam signal and the rotary signal, establish a dither zone associated with the target position, store data indicative of the established dither zone in the dither zone memory, establish a dither time associated with the dither zone, and cause the optical system to operate in the target dither mode wherein the reference beam moves within the dither zone for an amount of time equal to the dither time.

摘要： A laser transmitter includes an optical system arranged to generate laser beam and configured to project the laser beam radially so as to define a plane through which the laser beam is projected. A positioning device is coupled to the laser transmitter for adjusting an angular orientation of the optical system with respect to a first axis and with respect to a second axis. The angular orientation of the laser transmitter is adjusted so that the plane through which the laser beam is projected has a first slope with respect to the first axis and a second slope with respect to the second axis. A rotary encoder is arranged to determine a rotary position of the laser beam as it rotates to define the plane. A target is positioned in an alignment direction corresponding to the direction to which the laser transmitter is to be aligned. The laser transmitter may be aligned with respect to the first axis, the second axis or some other reference. A processor, in conjunction with a detector, determines the alignment direction. Once the alignment direction is determined, the processor calculates a first calculated slope and a second calculated slope and causes the positioning device to adjust the angular orientation of the optical system accordingly so that the plane through which the laser beam is projected corresponds to the first slope and the second slope in the alignment direction.

摘要： A system and method for checking and calibrating, if necessary, the orientation of a rotating laser beam as projected by a laser transmitter is provided. The laser transmitter is initially adjusted so that the rotating laser beam defines a plane which will be substantially horizontal if the transmitter is properly calibrated. A retroreflective target is positioned a predetermined distance from the transmitter. A known point on the transmitter is aligned in the direction of the retroreflective target. The laser beam is reflected from the retroreflective target back to the laser transmitter. A photodetecting system within the laser transmitter generates a signal representative of the position of the laser beam on the target. The laser transmitter is then rotated about a reference axis until the position of the laser beam on the target is determined with respect to each of the remaining coordinate axes. A processor is programmed to generate a calibration signal in response to the signals from the photodetecting system. The calibration signal may be used to indicate that the laser transmitter needs to be calibrated, or to provide an indication of how to calibrate the laser transmitter. Alternatively, the calibration signal may be used to calibrate the laser transmitter automatically.

摘要： A system for distinguishing real target reflections from ghost target reflections for use in adjusting the orientation of a plane defined by a rotating laser beam from a laser transmitter is provided. One or more retroreflective targets are positioned in desired locations along a rotational arc to define the desired plane through which the laser beam is rotated. The laser beam rotates back and forth scanning for targets positioned along the rotational arc. The laser beam is reflected from the targets to the laser transmitter for processing. A plurality of detection zones are established within the rotational arc. The detection zones are associated with a direction of rotation of the laser beam so that the laser beam traverses a target prior to traversing a potential shiny surface which could cause a ghost target reflection. As the laser beam scans a target prior to a shiny surface, reflections received after a target reflection are ignored as being potentially invalid reflections. Once a true target reflection is received, the orientation of the laser beam is adjusted until the laser beam traverses the center of the target.

摘要： A blade control system is configured to control the spatial orientation of an earthmoving blade mounted on a frame of an earthmoving machine for working a surface of earth to a desired shape. The blade slope angle required to maintain a selected cross-slope angle is calculated and the blade slope is then controlled so that the sensed blade slope angle is substantially equal to the calculated blade slope angle. The method and apparatus of the present invention is capable of maintaining the desired cross-slope even when the motorgrader is steered through a turn. The control system includes an input circuit, a sensor system and a processor. The input circuit is arranged to generate an output signal representative of the desired shape of the surface of earth to be worked. The sensor system includes a first sensor coupled to the frame of the earthmoving machine to generate a first signal indicative of a longitudinal slope angle of the frame with respect to horizontal. The sensor system also includes a second sensor coupled to the frame to generate a second signal indicative of a turn angle of the frame relative to a direction of travel of the blade. The processor is electrically coupled to the input circuit and the sensor system and is programmed to control the spatial orientation of the blade in response to at least the output signal from the input circuit, the first signal from the first sensor and the second signal from said second sensor so as to maintain the selected cross-slope angle.

摘要： An arrangement is provided for determining the relative angular orientation between an excavator bucket and the dipper stick of an excavator. The excavator bucket is mounted on a bucket linkage that is pivotally secured to the end of the dipper stick. An hydraulic actuator has an hydraulic cylinder pivotally connected to the dipper stick, and a piston pivotally connected to the bucket linkage. Extension or contraction of the hydraulic actuator causes the excavator bucket to be pivoted by the bucket linkage with respect to the dipper stick. A cable extension linear position transducer having a transducer casing, a sheath extending from the casing, and an extensible cable extending from the sheath, provides an electrical output related to the extension of the cable from the sheath. A transducer mounting secures the casing of the cable extension linear position transducer in fixed relationship to the hydraulic cylinder. A clip secures the extensible cable to the piston. By this arrangement, extension or contraction of the hydraulic actuator causes the output of the transducer to vary, thus providing an electrical output related to the relative angular orientation of the excavator bucket with respect to the dipper stick.

摘要： A light detection system is provided including a switching circuit connected to an inductor shunted across a photoelectric cell and operative to switch between a light detection state and a charge storage state, wherein the light detection state causes a majority of current flowing through the inductor to bypass the charge storage circuit, and wherein the charge storage state causes a majority of current flowing through the inductor to pass through the charge storage circuit. In one embodiment of the present invention, the switching circuit is changed to the light detection state during a first period of time during which the laser beam is in the vicinity of the photoelectric cell and to the charge storage state during a second period of time during which the laser beam is remote from the photoelectric cell.
