    Abstract: An axial alignment aid for remote control operations and related method are provided. A mirror located on a first movable member gathers light from its field of view in front of the first member and reflects it at right angles to a beam splitter which reflects the light at right angles to a video camera on the first member. A laser, also on the first member, projects a thin beam of light through a beam expander and a beam-expander lens template which gives the projected beam a pattern. The beam then reflects off another mirror, passes through the beam-splitter and is reflected off the original mirror. The beam is then projected on-axis with the first member (coincidentally on-axis with the video camera's field of view), and is inverted to match the original pattern. A reflective visual indicator or target is mounted on a second member so that its optical axis is collinear with the axis of the second member. An off-axis rotation of the first member to the right of the operator's perspective will result in a back-projected laser spot to the right of center on the visual indicator's front surface. On the other hand, rotation of the first member to the left of the operator's perspective will cause the spot to appear to the left of center on the front surface. Finally, if the operator centers the back-projected spot on the front surface of the visual indicator by moving the first member via a feedback control circuit, the laser light will be reflected exactly on axis with the center of the visual indicator. Positive indication of precise alignment of the first and second members is thus achieved and the first member can be safely and accurately docked with the second member.

    Abstract: An apparatus for automatically dispensing and taking-up a flexible communications cable such as an optical fiber includes a motor-driven reel which is mounted on a movable member, such as a vehicle. The fiber passes through a pivotably mounted tension control arm, whose angular position is detected to control the motor. Depending on the position of the tension control arm, the reel may be rotated in one direction to relieve fiber tension, it may be rotated in the opposite direction to take-up slack, or it may remain quiescent. The reel is mounted on a pipe which channels the inner end of the fiber to a rotary optical coupler, thereby permitting the fiber to be used for optical communication as the vehicle moves. The level-winding mechanism similar to that in a fishing reel may be used to control the windings on the reel, and a pivotably mounted plate may be pressed against the upper layer of fiber on the reel in order to keep it from unraveling.

    Abstract: Two-wire signal transmitter and method in which a very low-level Alternating Circuit (AC) input signal sensed at a remote circuit at a first end of a signal path is added to a low-level Direct Current (DC) bias signal provided by a local circuit that is located at a second end of the signal path. In a preferred embodiment, the remote circuit is electrically coupled to and powered by the local circuit through a two-wire path interconnection, typically a shielded twisted-pair cable. The DC bias signal has sufficient level to overcome minimum ratings of electrical contacts, thereby to pass the sensed very low-level AC input signal reliably through the poor electrical contacts that are used, for instance, for connecting electronic circuits that run the length of a railway train. In a preferred embodiment, the use of a unity gain current amplifier as a part of the remote circuit reduces the signal degrading effects of long signal paths, but does not amplify the AC input signal, thereby retaining known pre-determined railroad vitality requirements. An output signal is provided that is an AC coupled, isolated, non-amplified representation of the AC input signal. An alternate preferred embodiment utilizes no active amplifier as a part of the remote circuit, thereby providing a signal transmitter and method that is less complex, has lower cost, requires smaller packaging, and has somewhat better long-term reliability than the preferred embodiment utilizing the active amplifier in the remote circuit.
