Patent number: 11905898Abstract: A method of automated timing of engine startup for an aircraft is provided. The method comprises receiving data inputs regarding a number of factors influencing a time to departure for the aircraft and receiving data inputs regarding a number of factors influencing time to start and set takeoff power for a number of engines on the aircraft. An engine startup countdown is calculated based on a comparison of a nominal time to departure with a nominal minimum time to start and set takeoff power for the engines, wherein the nominal time to departure is based on the first data inputs and the nominal minimum time to start and set takeoff power is based on the second data inputs. Upon completion of the countdown an engine start signal is sent.Type: GrantFiled: December 19, 2019Date of Patent: February 20, 2024Assignee: The Boeing CompanyInventors: Jeffrey S.

Patent number: 8841898Abstract: Described herein is a self-powered system for detecting a current spike. The current spike is delivered through a current return network that energizes a resonant circuit to produce an alternating electrical output. The output is rectified by a rectifier into direct output that is then transferred to an integrator circuit. The integrator circuit slowly builds to and dissipates from a voltage threshold corresponding to an output transistor. When the output transistor is triggered by the voltage threshold this trigger is communicated to a fault monitoring software that recognizes the current spike.Type: GrantFiled: October 25, 2011Date of Patent: September 23, 2014Assignee: The Boeing CompanyInventor: Bruce Van Deventer

Patent number: 6225810Abstract: A loop resistance tester (LRT) for shield integrity testing comprising three elements: a “drive” current coupler, a “sense” current coupler, joint probes, and an instrument assembly. A low-power excitation current is sent from the instrument into the drive coupler, which is essentially a transformer. This induces a current in the electrical cable under test, as long as that cable and the connected structure form a continuous current path, or loop. This induced loop current is detected by the “sense” current coupler (transformer) and is measured by the instrument. The ratio of the loop voltage to loop current, as phasor values, gives the complex loop impedance, the real part of which is the loop resistance.Type: GrantFiled: February 12, 1998Date of Patent: May 1, 2001Assignee: The Boeing CompanyInventors: Erik L.

Patent number: 5223708Abstract: An alignment insensitive optical position sensor produces a signal indicative of the position of an element in respect to a monitoring point. The position sensor (50, 100, 120, 180, 200) includes a light source (56, 126) that provides a test light and a reference light of different wavelengths. The test light and reference light are conveyed through an optical fiber (68, 128) and collimated by a lens (70, 110, 144) along a path toward an encoded track or surface (72, 102, 138, 152, 204, 206). The encoded track or surface includes a plurality of metallic dots (74, 104, 140, 154) that are of varying size and/or density to produce a variable reflectivity. The encoded surface also includes an interference filter (76, 106) that reflects the reference light, but transmits the test light, due to the differences in their wavelengths.Type: GrantFiled: October 4, 1991Date of Patent: June 29, 1993Assignee: The Boeing CompanyInventor: Bruce Van Deventer

Patent number: 4928008Abstract: A light transmission filter for transmitting a beam of light of any wave length. The filter is made up of a pattern of opaque figures positioned along a transparent substrate. The spacing between figures is varied along the substrate so that the beam of light intercepted by the filter is variably transmitted as a selected function of the longitudinal position of the filter relative to the beam of light. The spacing of the figures along the substrate is selected to achieve a light transmission characteristic for the film in accordance with a desired mathematical function. An optical analog position sensor for sensing the position of a movable member along a prescribed path including the optical transmission filter attached to the movable member with the substrate having a longitudinal configuration corresponding to the prescribed path. The intensity of a fixed beam of light transmitted through the filter indicates the position of the member.Type: GrantFiled: December 11, 1987Date of Patent: May 22, 1990Assignee: The Boeing CompanyInventors: Raymond W. Huggins, Bruce Van Deventer, Glen E. Miller
