摘要： A voice track is recorded on one track of a dual track recording device, typically a tape recorder. On a second track of the recorder an animation signal is recorded characterized by the signal having a frequency at any given time indicative of the then currently desired animation condition. A character is provided having a tape playback unit therein for playing back such pre-recorded dual track tapes, the character having an amplifier and speaker for reproducing the audio information, and a servo motor having a drive system for driving the character mouth elements and eyes with the desired animation, the drive system having a feedback device thereon for providing a feedback signal to the servo motor control. The electronics in the character which is responsive to the animation control signal provided by the playback unit to provide the servo motor drive signal effectively updates the servo motor drive signal on each cycle of the animation control signal received from the playback unit.

摘要： In accordance with the method, first and second substantially parallel conductors are placed along a pathway and coupled to a controller in a manner so that each may carry a current independently controllable by the controller. A sensing coil is placed in a vehicle having a coil axis approximately perpendicular to the plane of the conductors so as to sense the varying magnetic field caused by varying currents through the two conductors. The controller repetitively provides a half-cycle of current of a given frequency in one of the two wires, immediately followed by another half-cycle of current of the opposite polarity or direction in the other of the two wires. The sensing coil on the vehicle senses the magnetic field caused by these varying currents in a manner dependent upon its proximity to each of the two wires, and controls the vehicle steering responsive thereto, sensing a substantially balanced wave when centered between the two wires, a positively distorted wave when closed to one of the wires and a negatively distorted wave when closer to the other of the two wires. Modulation of the frequency of the current in the two wires provides communication capability from the controller to the vehicle for remote steering and speed control. Apparatus for carrying out the method and alternative embodiments are disclosed.

摘要： A cursor control device having particular application to a computer display system is disclosed. The cursor control includes a unitary frame, having a domed portion substantially surrounding and retaining a ball which is free to rotate. X-Y position indicating means are provided, such that rotation of the ball provides signals indicative of X-Y positions on the display system. The ball is free to "float" in the vertical direction within the dome, and thereby maintain good surface contact. X-Y positions are established by movement of the control device over a surface. A display system and method is disclosed for use in conjunction with the cursor control device, which permits a user to select command options simply by movement of the displayed cursor over a "pull-down" menu bar.
