摘要： A rotating laser beam projector includes a power controller having a micro controller coupled to a laser power circuit which determines whether the laser beam emitted by the projector is rotating or stationary. When the laser beam is rotating, the laser power circuit delivers a first level of continuance power to the laser. When the laser beam is stationary, the laser power circuit delivers a second level of continuance power to the laser which is less than the first level of power. The micro controller communicates messages from the laser beam projector to a remotely positioned sensor assembly by rotating the laser beam at a first speed when no message is to be communicated and rotating the laser beam at a second speed, different from the first speed, when a message is to be communicated. The laser beam projector includes a bridge for delivering electrical power to a pendulum-supported device from a stationary source. A first conductor is affixed to the stationary source and a second conductor is electrically coupled to the pendulum-supporting device. At least one wire is bonded, such as by ball-and-stitch bonding, from the conductor to the second conductor across a gap.

摘要： A control for an excavator controls the position of the bucket cutting edge to a desired depth accurately by a calibrating laser receiver mounted on the excavator stick member and passed through a stationary laser plane wherever the stick is moved into or out of a trench. Linear position encoders monitor the length that the actuating cylinders are extended and lookup tables convert the encoder outputs to angle representations for determining the positions of the laser receiver and the cutting edge. Other lookup tables are utilized to avoid time-consuming iterative calculation procedures to provide real-time digital process solutions of trigonometric functions. The apparatus includes a unique laser receiver comprising a plurality of linearly aligned photo receptors with associated circuitry for producing an output representative of the receptor illuminated or, if a group of receptors are illuminated, the centermost receptor illuminated.

摘要： An apparatus and method for controlling a hydraulically operated construction machine, having a plurality of tandem articulated members which are controlled in a manner that movement of one of the members is controlled in response to movement of another of the members, in order to move the members in a predetermined pattern. The members are controlled in response to the anticipated future movement of the another member. Anticipated future movement of the another member may be determined, for example, as a function of the present position and velocity of the another member and system delay in movement of the another member. Where the another member is controlled manually by an operator control lever coupled with a manual hydraulic control valve, anticipated future movement may be determined by monitoring actuation of the control lever.

摘要： A compact laser construction instrument intended for use by the average construction contractor. The instrument is capable of generating a rotating plane of laser light and a beam of light that is perpendicular to the rotating plane. It includes a beam generator adapted to generate a beam of collimated light along a given axis. A rotating platform is provided for supporting the beam generator for rotation in a plane parallel the axis of the collimated light and about a rotation axis that is perpendicular to the axis of the collimated light in order to generate a plane of light.

摘要： A surveying instrument is provided which includes an optical sighting scope having a sighting barrel and orthogonal reticular lines visible to an observer viewing through the barrel, in combination with a miniature light plane generator that is oriented to produce a plane of light that is coincident with one of the reticular lines in the direction viewed by an observer viewing through the barrel of the optical sighting scope. The miniature light plane generator includes a laser diode that generates a beam of light, a collimating lens positioned within the beam of light generated by the laser diode in order to produce a beam of collimated light, and a fan lens positioned within the beam of collimated light in order to divert the beam of light into a plane. The miniature generator additionally includes a power supply that supplyies power at a low duty cycle. Because of the resulting reduction in electrical power required by the generator, the components making up the generator, including a battery for supplying energy to the power supply, may be combined within the housing of the optical sighting scope in order to provide a compact instrument.

摘要： A self-levelling laser generator apparatus (10) includes a housing (12), a light source in the housing which produces a beam of collimated light, and a self-levelling mechanism (18). The self-levelling mechanism includes an electronically controllable signal source, such as a digital potentiometer (46), which is provided a command (44a-44c) from a programmed computer (38) to produce a controllable output (48). The output of (48) the digital potentiometer is summed by a summing circuit (34) with the output (28) of an inclination sensor (24) in order to produce a compensated inclination signal (36) which is provided as an input to computer 38. The computer additionally receives a calibration input (20, 21) indicative of deviation between the inclination of the laser beam and a predetermined grade. The computer produces a drive signal (50a, 50b) for the self-levelling mechanism (52, 54) that is a function of the compensation inclination signal. The output (44a-44c) supplied by computer 38 to the digitally controllable signal source (46) is a function of the tilt of the inclinometer and calibration numbers entered through calibration inputs (20, 21).
