b)
The receiver is located inside the beacon post box. It consists of
two small printed circuit boards, with the receiver being the smallest,
mounted to the larger "mother" board. The receiver is a superhetrodyne
using two separate antennas. The electronics of the receiver will "lock" on
whichever antenna has the most signal strength. This design is a means
of avoiding interference problems and reducing the effects of signals
bouncing off buildings and cars. The receiver will work with only one
antenna but the dependability will be degraded. The signal from the
radio's circuit board is fed directly to the "mother" board through a
connector. The "mother" board decodes the signal and energizes one of
four output wires, which corresponds to the command being issued by the
remote. The radio receiver should be able to operate with the remote at a
distance of 100 feet.
15) The
steering handle
is made of heavy gage tubing that is formed, welded and
nickel-plated. It contains not only the means for manually operating the
machine, but is also fitted with the system's control panel and throttle grip.
a)
The
throttle-grip
is located on the right side of the handle and a
stationary hand-grip is on the left. A protective bar is welded to the handle
to protect the grips from damage should the machine come in contact with
a wall or the edge of a doorframe. The throttle grip turns about 90
degrees, in one direction only. Turning the throttle causes a potentiometer
to change the voltage on its output wire from zero volts, (machine not
moving) to about 5 volts (full speed operation). When the control panel
has selected "remote" operation, the throttle grip is electrically
disconnected.
b)
The
control panel
is the central operating point for the machine.
The control panel box is mounted at
the
top of the steering handle with 4
screws. An opening in the bottom of the control panel box matches an
opening in the steering handle and is the means for getting a multi-wire
cable from the push-button controls to the electronic equipment located
under the machine's cover. This box has mounted to it a key switch and
emergency stop switch, both of which are "closed" when in operation. The
connecting leads to both of these items are plugged into the control
panel's printed circuit board. The control panel cover contains a bezel
plate, printed circuit board, membrane and associated hardware. The
printed circuit board contains three push-button switches that are activated
by pressing through the thin sections of the white membrane. These three
switches are labeled on the membrane's top surface with the following
selections:
1. Manual or Remote operation
2. Forward or Reverse operation
3. Stop
