Patent number: 11649744Abstract: According to some embodiments, an apparatus comprises an air pump configured to couple to a capstan, and a pneumatic cylinder coupled to the air pump at a first end of the pneumatic cylinder. The pneumatic cylinder comprises a piston. Rotation of the capstan in a first rotational direction causes the air pump to provide air pressure to the first end of the pneumatic cylinder. In response to the air pump providing air pressure to the first end of the pneumatic cylinder, the piston of the pneumatic cylinder moves in a first linear direction. The piston is coupled to a longitudinal beam of a longitudinal door system of a railcar. In response to the piston moving in the first linear direction, the longitudinal beam moves in the first linear direction, opening a door of the longitudinal door system.Type: GrantFiled: October 27, 2020Date of Patent: May 16, 2023Assignee: TRINITY RAIL GROUP, LLCInventors: Robert J. DeGroot, Kenneth W. Huck

Publication number: 20070004344Abstract: Wireless communication systems (100, 800) comprise mobile units (118, 802) provided with a directional coupler (206) and circuit (220) for measuring the complex reflectance (phase and magnitude) of antenna (202) of the mobile units (118, 802). The system (100, 800) has, either in the mobile unit (118, 802) or elsewhere, a processor (238, 808) programmed to perform pattern recognition of the near field environments of the mobile units (118, 802) by using the complex reflectance measurements as feature vectors. Information as to the near field environment at the time of wireless connection drops is suitably accumulated and is used in network upgrade planning and/or mobile unit design evaluation. The complex reflectance is alternatively used to discriminate antenna faults. Alternatively, near field environments that tend to degrade wireless communication performance are detected by the mobile unit using the complex reflectance and the mobile unit then alerts the user.Type: ApplicationFiled: June 29, 2005Publication date: January 4, 2007Inventors: Robert J. DeGroot, Nicholas E. Buris
