Publication number: 20240200948Abstract: A navigation system for an aircraft includes a microelectromechanical systems inertial measurement unit (MEMS-IMU), a camera that captures, over time, a series of images of the terrain below the aircraft, a terrain map comprising terrain elevation data, an inertial navigation system (INS) and an optical terrain-referenced navigation unit (O-TRN). The INS generates a first position estimate based on one or more signals output by the MEMS-IMU. The O-TRN identifies a terrain feature in an image captured by the camera, derives a terrain height estimate of the terrain feature, and generates a second position estimate based on a comparison between the terrain height estimate and terrain elevation data extracted from the terrain map. The navigation system generates a third position estimate based on the first position estimate and the second position estimate.Type: ApplicationFiled: December 13, 2023Publication date: June 20, 2024Inventor: Geoffrey Thomas Henderson

Patent number: 11029159Abstract: A terrain-based navigation system include at least three laser range finders, each fixedly mounted to a vehicle body, each pointing in a different direction and arranged such that they can be used to calculate terrain gradient in two dimensions. Existing terrain-based navigation systems for aircraft that use a radar altimeter to determine the distance of the vehicle from the ground make use of the large field of view of the radar altimeter. The first return signal from the radar altimeter may not be from directly below the aircraft, but will be interpreted as being directly below the aircraft, thereby impairing the chances of obtaining a terrain match, or impairing the accuracy of a terrain match. The use of a plurality of laser range finders each fixedly mounted to the vehicle body allows more terrain information to be obtained as the terrain can be detected from the plurality of different directions.Type: GrantFiled: September 9, 2019Date of Patent: June 8, 2021Assignee: ATLANTIC INERTIAL SYSTEMS LIMITEDInventor: Geoffrey Thomas Henderson

Patent number: 10180368Abstract: A method and apparatus for determining a bicyclist's bodily position, such as sitting or standing, while riding a bicycle. Sensors measure a force applied by the bicyclist to the pedals. The measurement data is analyzed to identify a feature, such as whether a radial force is higher or lower than a tangential force or whether a total vertical force is high or low, which is indicative of the bicyclist's bodily position. A series of changes in the bicyclist's bodily position during the ride is recorded. A series of changes in the geographic location of the bicyclist and/or a series of changes in one or more performance metrics while riding the bicycle may also be recorded. The series of changes in the bicyclist's bodily position, the geographic location, and the performance metrics may be correlated, graphically communicated in real-time or post-ride, and used to improve the bicyclist's performance.Type: GrantFiled: May 29, 2015Date of Patent: January 15, 2019Assignee: Garmin Switzerland GmbHInventors: Theodorus J.

Patent number: 10073821Abstract: A method and apparatus for representing two or more related markup language source files in a single delta file is provided. The markup language source files are represented in such a way that the delta file is easily processed to produce one or more merged combinations of the source files. The method and apparatus ensure that any one of the original files can be extracted from the delta file and the delta file remains a valid delta file for any remaining source files. The method and apparatus is adapted to enable the sources files to be aligned with respect to structurally significant elements and textual content so as to reduce repetitions in the delta file of common content. The method and apparatus are suited for use, but not exclusively, with XML documents and files.Type: GrantFiled: September 2, 2014Date of Patent: September 11, 2018Assignee: DeltaXML, Ltd.Inventors: Semer Geoffrey Thomas La Fontaine, Tristan Mitchell

Publication number: 20160041051Abstract: A method and apparatus for determining a power phase and other force-related performance of a bicyclist while riding a bicycle. Sensors measure a force applied by the bicyclist to the left and right pedals. The measurement data is analyzed to determine the power phase performance by correlating the force applied by the bicyclist to the left and right pedals with corresponding angles of the left and right cranks. A series of changes in the power phase performance during the ride is recorded. A series of changes in the geographic location of the bicyclist and/or a series of changes in one or more performance metrics while riding the bicycle may also be recorded. The series of changes in the bicyclist's power phase performance, the geographic location, and the performance metrics may be correlated, graphically communicated in real-time or post-ride, and used to improve the bicyclist's performance.Type: ApplicationFiled: May 29, 2015Publication date: February 11, 2016Inventors: Theodorus J.
