Patent number: 11802380Abstract: A track maintenance machine for carrying out track position corrections includes a machine frame movable by on-track undercarriages on rails of a track and a track position measuring system having two outer measuring devices and a central measuring device with a common reference base, relative to a longitudinal direction of the machine. The measuring devices are defined in their position relative to the rails. Two mutually aligned measuring chords are tensioned or stretched as a reference base between the outer measuring devices. The central measuring device includes a measuring transducer for detecting position data of the two measuring chords. The position data are fed to an evaluation device in order to determine a longitudinal level for each rail and a versine. Thus, two measuring chords are sufficient to detect all of the track parameters. A method for operation of a track maintenance machine is also provided.Type: GrantFiled: October 5, 2017Date of Patent: October 31, 2023Assignee: Plasser & Theurer Export von Bahnbaumaschinen Gesellschaft m.b.H.Inventors: Samuel Wollanek, Leopold Fruehwirt

Patent number: 11779242Abstract: Systems and methods use a three-dimensional snapshot of an infant, child, adolescent, or adult where the subject may have bent legs and an unaligned head position, to provide an estimate of human length. The system identifies anatomical features from the digital information and generates a virtual skeleton. The cumulative distances between pseudo-joints of the virtual skeleton provide an estimate of human length. Comparing length estimates from multiple three-dimensional snapshots of the same individual acquired over time provide an indication of growth of the infant, child, or adolescent. Daily estimates of length can detect growth faltering sooner than less frequent estimates of length, which can lead to timely intervention.Type: GrantFiled: June 2, 2022Date of Patent: October 10, 2023Assignee: PIXA4 LLCInventors: James Martin Swanson, Robert Clay Isenhart
