  • Publication number: 20210123362
    Abstract: 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..

  • Publication number: 20070004344
    Abstract: 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.

  • Patent number: 6446711
    Abstract: Difficulties in obtaining consistent bonds of high quality between side pieces and tubular headers (10), (12) in heat exchangers are avoided in a side piece (42) that extends between the headers (10), (12) and which has circular recesses (48) at each end (44), (46). The recesses (48) define resilient fingers (56), (58) which may separate to receive the ends of the headers (10), (12) and frictionally grasp the same, eliminating the need for fixturing at this location and assuring a strong consistent gripping of the headers (10), (12), by the end piece (42) to assure consistent bonds of high quality.

  • Patent number: 5945964
    Abstract: A first coil (110) resonant at a first frequency, and a second coil (120) resonant at a second frequency, coupled to a conductive straight portion (140) of an antenna element (130) to form a multi-band antenna structure. The first and second coils (110) and (120) are preferably of different axial lengths and circumferences, wound in opposite directions and coaxially disposed about the antenna element (130). Additional coils can be added to accommodate additional bands and an upper coils (150) can be used to realize a multi-position structure.

  • Patent number: 5808586
    Abstract: Multiple helical coils (110, 120, 130) are placed side-by-side and coupled to a conductive straight portion (140) of an antenna to provide a multi-band antenna structure. The helical coils (110, 120, 130) are distanced from one another to sufficiently eliminate coupling interference therebetween. A portable radio capable of communication in many different frequency bands utilizing a single, compact antenna structure is thus realized.
