摘要： A transmitter for an alignment system in which a field of electromagnetic radiation is propagated in a non-planar reference cone is disclosed. The transmitter includes a chassis with a source fixed to the chassis for providing a beam of electromagnetic radiation and an optical deflector which converges toward the source reflects the beam into an omni-directional cone of radiation. A flexible support having an omni-directional stiffness supports the optical deflector in the beam to reflect the reference field in a level orientation when the chassis is level. An angular error in the orientation of the chassis from level results in the optical deflector deviating from the aligned position to maintain the reference field in the level orientation. Damping of the deflector is also provided for and sensors detect when the angular error of the chassis has exceeded an allowable amount.

摘要： A transmitter for an alignment system in which a field of electromagnetic radiation is propagated in a non-planar reference cone is disclosed. The transmitter includes a source for providing a collimated beam of electromagnetic radiation directed parallel to a beam axis. A cantilever strand supports a bob within the beam. The bob has a conical reflecting surface to reflect the collimated beam conically. Optimally, the cantilever strand and bob are chosen to provide a deflection between the bob and plumb which is substantially one-half of any angular error between the beam axis and plumb. In an especially preferred form, a housing surrounds the bob and has inner and outer surfaces which minimize temperature effects on the orientation of the reference plane. Also, detectors are provided to sense when the angular error between the beam axis and plumb is outside of an acceptable range.

摘要： This invention provides a method for controlling the path of a crop spraying aircraft in making repeated traverses over a field to insure that each traverse is laterally spaced from the adjacent traverse by the proper distance to assure adequate coverage of the crop land with the material being sprayed and avoiding over-lapping or insufficient coverage of any portion of the crop land. In accordance with the method of the invention, the crop spraying aircraft carries a rotating laser beam transmitter and receiver, and the transmitted beam is reflected from a plurality of reflectors located on the ground at known positions relative to each other to provide successive reflections of the transmitted laser beam from which the angular positions of the aircraft relative to the reflectors may be continuously determined. After an initial pass over the field to establish the spray path, the position of the aircraft may be continuously computed by a microprocessor and an error signal generated during each subsequent pass to indicate to the aircraft operator whether the aircraft should be steered more to the right or left to stay on the desired spraying path.

摘要： A laser beam three dimensional position measurement system includes a laser transmitter mounted at a stationary reference position at a work site and a receiver mounted on a mobile machine at the site. The transmitter produces a laser reference plane by sweeping a laser beam about the transmitter. The receiver includes a retroreflector which intercepts and reflects laser energy back to the transmitter when the laser beam sweeps past the retroreflector. The system also includes at the transmitter a circuit composed of a photodetector, timer, clock and counter. The photodetector senses laser energy reflected back to the transmitter from the retroreflector. The timer modulates the laser beam produced by the transmitter in response to detection of the beam. The counter is connected to the clock and timer, and is enabled by the timer to start counting electrical pulses received from the clock when the beam is modulated. The counter is disabled to stop counting electrical pulses when the modulation is detected. The number of pulses counted by the counter is indicative of the range of the receiver from the transmitter. The orientation of the beam relative to a fixed reference axis at the time reflected laser energy is detected defines the direction of the receiver relative to the transmitter.

摘要： A system which is preferably employed in a laser alignment instrument produces up to five orthogonal beams from a single laser diode beam. In one embodiment the optics take advantage of the elliptical shape of the beam from a laser diode which when collimated produces a plurality of orthogonal beams by reflection off a plurality of 45.degree.-angled reflective surfaces intercepting outer portions of the beam. In one preferred embodiment a solid reflective element was four 45.degree.-angled facets to produce four beams from outer portions of a preferably non-elliptical beam, and a fifth orthogonal beam is produced by transmission of a central portion of the beam through the element. The element can be solid glass, or it can be glass or other material with a central hole.

摘要： A system preferably in the form of an accessory module corrects for tilt angles of a distance measuring laser projecting instrument. The housing of the module includes a compensating mirror mounted on a pendulum which bends with tilt angle by one-half the amount of the housing tilt, so as to reflect the outgoing beam to truly horizontal. In a preferred embodiment a fixed mirror is also included so that the distance measuring instrument can be laid or held approximately horizontally so that its generally horizontal beam is first reflected by the fixed mirror up to the pendulous compensating mirror. The distance measuring instrument preferably has an internal correction to subtract the additional optical path length induced by the use of the accessory module. This may be activated by a switch on the module or automatically when the module is attached to the distance measuring instrument.

摘要： A construction laser tool which projects a plumb beam is provided with a marking template, movable and separate from the tool's housing but securable to the housing, for transferring a point on a floor to the laser beam or, in another case, for transferring the beam to locate a point on the floor. The template has a marker such as a hole to receive a pencil, and the marker is positioned under the laser tool housing, on the vertical line of the plumb beam where the floor point of interest cannot be seen, when the plumb beam is projected at a point on the ceiling. To accurately mark the floor point, the user holds the template in place on the floor and moves the laser tool away to gain access to mark the point. The reverse procedure is used to align the plumb beam over a known point on the floor. Several arrangements involving sliding templates are disclosed.

摘要： A gas valve which is particularly useful in a laser gas fill system requiring repeated fillings includes a conduit positioned between high and low pressure gas regions. Within the conduit is a restriction, and this restriction is closed by a meltable solid material. When the valve is to be opened, heat is applied to the meltable solid material, either internally or externally, causing at least some of the material to flow and allow the passage of gas from the higher pressure region to the lower pressure region. When the pressure between the two regions has substantially equalized, or at least the pressure differential has greatly diminished, surface tension associated with the restriction in the conduit pulls the liquified material back into place to close and reseal the valve, at which point heat application is dicontinued so that the material again becomes solid. The geometry of the restriction is such that all or substantially all of the liquid material will return essentially to its original position, allowing the valve to be used in repeated on/off cycles. Also, the valve geometry and heat application are such a high pressure differential will not cause the liquified material to blow away from the valve due to high velocities.
