    摘要： Field-deployable spatial positioning or measurement systems are provided for improved versatility, reliability and performance. The spatial positioning or measurement systems use rotating laser fans or beams for positioning and measuring and include a system integrated field-deployable length standard that uses a reelable tape with positional indents. The systems further include the use of labyrinth seals at interface volumes between rotating laser heads and transmitter assemblies to prevent ingress of contaminants and allow for elimination of the use of rotary seals. Further, new dynamic leveling techniques are provided to plumb positional laser transmitter systems. Still further, strobe beam configurations are provided for improved near/far performance and a vertical mode sensing scheme that allows switching to measuring tall structures when needed.

    摘要： Non soil-invasive four-parameter rapid unnatural dual component selective illumination protocol (UDCIP) for plant eradication using a process time under one minute. Application of a relatively low level of non-mutating UV-A optical energy to root crowns and/or soil grades allows below-ground UV-A penetration into soil to illuminate root crowns, and when preceded by or coincident with an above ground near-IR defoliation and root crown illumination step, results in an unexpected rise in lethality. Very high lethality, including 100 percent, is obtained using low deposited energy. UV-A optical energy can be delivered to root crowns and adjacent soil via a UV-transmissive knive blade.

    摘要： Plant eradication using by inflicting upon a plant root (R) unnatural hot wound mechanical and thermal trauma delivered from a hot stab knife (V) which produces a stab gash (K) sufficiently deep to traverse plant cortex (C) and penetrate to plant xylem (X), simultaneous with or followed by heating the damaged area to a temperature of higher than 70 C, preferably 200 C for a sufficient time to cause cellular damage to the plant root. The root and hot stab knife may be shrouded to increase the temperature adjacent the stab gash. Preferably, the stab knife is formed to be sufficiently acuate and flat so as to allow a surface/volume ratio for the stab knife to be at least twice that of a cone of similar size and extent. Unhealable damage results, believed to caused by role conversion of organisms in the rhizosphere from symbiosis to antagonism.

    摘要： Controlled gap thin blade shear process to cut grass using a low energy sickle mower. A thin dull blade moves without interference across a stator. Blades and stators are not biased or pressed together while cutting, but rather the cutting blade is guidingly supported by upper and lower stators formed and positioned to maintain forceably a total controlled gap (Z) therebetween of preferably 1-5 mils. The cutting blade is thin (10-50 mils). Tensile failure of grass is avoided. Torque management system performs motor load monitoring and modulation of blade position. To reject obstructions and clean the blade, the blade can reverse, jitter, or reciprocate. Instead of attempting to slice or slam through obstructions using a high torque prime mover, a low energy low torque prime mover is utilized with intelligent reversing, obstruction clearing, and blade cleaning that saves energy, reduces noise, rejects obstructions, and prevents blade damage or operator injury.

    摘要： Low energy non-interference unbiased shear process employing a thin dull blade laterally moving between upper and lower stators. Blades and stators are not biased or pressed together while cutting, as is done with a pair of scissors. Instead, the dull cutting blade is guidingly supported by said upper and lower stators, and the upper and lower stators are sized and formed such that a thickness of a cutting zone (M) formed therebetween exceeds the thickness of a blade zone (VZ) formed by the dull cutting blade, by a total controlled gap (Z) of preferably between 1 and 5 mils (0.0254-0.127 mm). The cutting blade is preferably thin in relation to grass cross section, preferably 10 to 50 mils (0.254 mm-1.27 mm). This arrangement provides two true shearing sites for grass at upper and lower leading edges of the blade. Adequate blade swipe frequency is provided, with gentle C-shape blade profiles yielding self-cleaning blades with lower running friction. Tensile failure of the grass is avoided. A torque management system performs motor load monitoring and modulation of blade position. To reject obstructions and clean the blade, the blade can be made to reverse direction, jitter, or reciprocate. Instead of attempting to slice or slam through obstructions using a high energy, high torque prime mover, a low energy low torque prime mover is utilized in conjunction with an intelligent reversing, obstruction clearing, and blade cleaning system that saves energy, reduces noise, frees and rejects obstructions, avoids high power surges and prevents blade damage or operator injury.

    摘要： A laser transmitter and a method of transmitting a reference laser beam are provided comprising an auto scan dither mode. According to one aspect of the present invention, a laser transmitter is provided comprising a laser detection module, an optical system, and a controller. The laser detection module is operative to produce a reflected laser beam signal. 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 reflected laser beam to the laser detection module. The optical system defines a rotational axis and the reference beam projects radially from the rotational axis. The search mode is characterized by movement of the reference beam through a rotational arc defined about the rotational axis and the target dither mode is characterized by movement of the reference beam through a dither zone occupying a portion of the rotational arc. The controller is programmed to produce selectively one of a target-sighted signal and a target-missing signal and produce a rotary position signal indicative of the position of the reference beam relative to the rotational arc. The controller is also programmed to identify a target position based upon the reflected laser beam signal and the rotary position signal and establish the dither zone about the target position. The dither zone is characterized by a dither range and the dither range is changed gradually in response to the target-sighted signal. The dither range is maintained substantially constant in response to the target-missing signal.
