Abstract

The present invention is for a precision grid surveyor having a stationary unit and a roving unit. The stationary unit has a light source unit that emits a light beam and a rotator to project the light beam toward detectors on a roving unit. The roving unit moves over an area to be surveyed. Further the invention is for a method of mapping details of hidden underground iron pipelines, and more particularly the location of bell joints.

Method and apparatus for providing a precise amount of gas at a precise humidity

Patent Hallman, Jr., Russell L.; Truett, James C.

A fluid transfer system includes a permeable fluid carrier, a constant temperature source of a first fluid, and a constant pressure source of a second fluid. The fluid carrier has a length, an inlet end, and an outlet end. The constant pressure source connects to the inlet end and communicates the second fluid into the fluid carrier, and the constant temperature source surrounds a least of portion of the length. A mixture of the first fluid and the second fluid exits via the outlet end A method of making a mixture of two fluids is also disclosed.

Method and apparatus for precision phasor measurements through a medium-voltage distribution transformer

Patent McEachern, Alexander; Hofmann, Ronald

A means and method for measuring precise voltage phasors on medium-voltage alternating current (AC) distribution grids, using existing distribution transformers as voltage sensors. The errors introduced by the distribution transformers are minimized by taking into account the transformer's vector impedance, combined with measuring the transformer secondary current phasor. The invention includes a means and a method of measuring the distribution transformer's vector impedance.

Method and apparatus for precision laser micromachining

Patent Chang, Jim [San Ramon, CA]; Warner, Bruce E [Pleasanton, CA]; Dragon, Ernest P [Danville, CA]

A method and apparatus for micromachining and microdrilling which results in a machined part of superior surface quality is provided. The system uses a near diffraction limited, high repetition rate, short pulse length, visible wavelength laser. The laser is combined with a high speed precision tilting mirror and suitable beam shaping optics, thus allowing a large amount of energy to be accurately positioned and scanned on the workpiece. As a result of this system, complicated, high resolution machining patterns can be achieved. A cover plate may be temporarily attached to the workpiece. Then as the workpiece material is vaporized duringmore » « less
