Patent number: 11892400Abstract: An absorption spectroscopy process uses a single radiation beam with two or more pulsed beams (including at least a signal beam and a reference beam) that are passed into a liquid sample to a variable effective depth and then reflected out of the liquid sample where it is detected and processed to obtain a value over a preselected time. As values are determined for multiple effective depths, a sampling dataset is obtained which is used to calculate a concentration level of a targeted particle in the liquid sample by use of calibration dataset obtained from use of known samples.Type: GrantFiled: August 25, 2023Date of Patent: February 6, 2024Assignee: AIRWARE, INCInventors: Thomas G Campbell, Jacob Y Wong

Patent number: 11747259Abstract: Increased precision for liquid absorption spectroscopy, especially for in vivo samples of human analytes, is obtained by varying the signal or signal and interference central wavelengths when the temperature of the sample site varies beyond a selected threshold used for determining standardized signal or signal and interference central wavelengths. The amount of variance for a central wavelength of the signal beam which includes 1,150 nm is approximately 2 nm or less.Type: GrantFiled: February 27, 2023Date of Patent: September 5, 2023Assignee: AIRWARE, INC.Inventors: Thomas G Campbell, Jacob Y Wong

Patent number: 4569629Abstract: Hub moment and driving torque is provided for a helicopter gimbal rotor by two-part flat springs that are in-plane with the rotor tilt point (P). The inboard end of an outward part of each spring is connected to the rotorshaft and the inboard end of an inward part of the spring is connected to the tiltable hub member. The outboard ends of the two spring parts are journaled together by an eccentric elastomeric joint that allows for spring foreshortening that accompanies rotor tilt.Type: GrantFiled: September 27, 1984Date of Patent: February 11, 1986Assignee: United Technologies CorporationInventors: Donald L. Ferris, Charles F. Niebanck, Thomas G. Campbell, Eric G. Olsen

Patent number: 4514143Abstract: A structure (10) for reducing vibratory airloading in a rotor blade (12) with a leading edge (14) and a trailing edge (16) includes a cut-out portion (18) at the trailing edge. A substantially wedge shaped cross-section, inertially deflectable tab (20), also having a leading edge (22) and a trailing edge (24) is pivotally mounted in the cut-out portion. The trailing edge (24) of the tab (20) may move above and below the rotor blade (12). A torsion strap (26 or 64) applies force against the tab (20) when the trailing edge (24) of the tab (20) is above and below the rotor blade (12). A restraining member (92) is slidably movable along the torsion strap (64) to vary torsional biasing force supplied by the torsion bar (64) to the tab (20). A plurality of movable weights (82) positioned between plates (84) and (86) vary a center of gravity of the tab (20). Skin (74) of the tab (20) is formed from unidirectional graphite and fiberglass layers.Type: GrantFiled: April 28, 1983Date of Patent: April 30, 1985Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventor: Thomas G.
