Abstract

A complete system for animating external features of a full size walk-around costume designed for the entertainment industry is disclosed. The animation system comprises two major parts: the costume itself and the programming/playback system. The complete system is lightweight and portable and gives complete freedom of motion to a person inside a walk-around costume. The costume is made to simulate life by the inclusion of motors or other devices which move the eyes, the eyelids, eyebrows, the ears, the nose, and the mouth. The mouth movement is controlled by a radio signal which may be synchronized with a prerecorded audio track. To give maximum spontaneity to expression and to reduce the time required to program costume movements, all other external features are controlled by the dancer inside the costume, using newly developed pressure sensitive finger switches which are activated by bending a finger.

Claims

1. A full-size walk-around costume apparatus comprising a costume, including a movable mouth, and a programming/playback system for controlling the movements of said mouth of said costume in synchrony with a prerecorded audio track, said programming/playback system including means for generating a tone, means for controlling the amplitude of said tone, means for converting said tone into a series of pulses to form a pulse chain which corresponds to said amplitude of said tone, means for modulating a carrier signal with said pulse chain and means for transmitting said modulated pulse chain, said costume further including means for receiving said modulated pulse chain, means for converting said modulated pulse chain into an electrical pulse, and means for controlling the position of said mouth with said electrical pulse.

2. The apparatus of claim 1 wherein said programming/playback system further includes means for controlling the mouth of each of several of said costumes simultaneously, with each pulse in said pulse chain selectively adapted to control each of said mouths of said costumes and wherein each costume includes means for selecting each said pulse from said pulse chain for controlling the movements of said mouth.

3. The apparatus of claim 1 comprising:

(a) at least one joystick including a potentiometer for controlling said amplitude of said tone;

(b) a multichannel programming tone generator including a tone generator for generating a tone signal of a predetermined frequency, the amplitude of which is varied by said joystick, said amplitude being associated with the position of said mouth of said costume;

(c) a multitrack tape recording including;

(1) switch means for selecting programming input from said multichannel programming tone generator or playback output to a multichannel transmitter, and

(2) record/play tape storage means for recording/playing tone signals generated by said multichannel programming tone generator; and

(d) said multichannel transmitter including;

(1) a pulse width modulator for converting said tone signal into a pulse whose width is linearly proportional to said amplitude of said tone signal,

(2) modulation means for modulating said pulse, and

(3) an antenna for transmitting said modulated pulse.

4. The apparatus of claim 3 wherein said modulations means comprises AM.

5. The apparatus of claim 4 wherein said multichannel transmitter further includes:

(a) a filter for reducing spurious outputs and interferences from said modulated pulse;

(b) a bridge for determining proper operation of said antenna; and

(c) an antenna tuner for minimizing reflected power as measured on said bridge.

6. The apparatus of claim 3 wherein said multichannel transmitter further includes:

(a) a preamplifier section with variable gain for compensating for any fluctuation in said tone signal input from said multitrack tape recorder;

(b) a fixed input signal generator for providing at least one input signal of a predetermined amplitude and switch means for selecting between said tone signal input and said at least one input signal; and

(c) means for displaying the level of said tone signal prior to conversion into said pulse.

7. The apparatus of claim 1 wherein said costume further include a sculpted head and face and means for moving parts of said head and said face.

8. The apparatus of claim 7 wherein said costume further includes actuators and linkages adapted to move said parts of said head and said face in response to an input pulse, a control mechanism for controlling said actuators and a power supply for providing power to said control mechanism and said actuators.

9. The apparatus of claim 9 wherein said parts include said mouth, a nose, a pair of eyes, eyebrows, eyelids and ears.

10. The apparatus of claim 9 wherein said control mechanism includes:

(a) an antenna for receiving said modulated pulse;

(b) a receiver for converting said modulated pulse to said pulse chain;

(c) means for recovering a pulse from said pulse chain which is intended for controlling said mouth of said character;

(d) finger switch means associated with said costume for selecting a separately generated pulse for controlling said mouth of character; and

(e) means for detecting the position of said mouth of said costume, comparing the width of a pulse, determining whether said pulse from said programming/playback system or from said finger switch means should be input to an actuator associated with said mouth, whereby said mouth of said costume is controlled by said finger switch means in reference to a pulse transmitted from said programming/playback system.

11. The apparatus of claim 9 further including:

(a) finger switch means for generating a pulse for separately controlling said nose of said costume; and

and

(b) means for determining the position of said mouth of said costume, for switching control to said finger switch means depending on said mouth position and for inputting a pulse to an actuator associated with said nose.

12. The apparatus of claim 9 further including:

(a) a plurality of finger switch means for generating a pulse for individually controlling each of said parts; and

(b) means for sensing the presence of said pulse and inputting said pulse to an actuator associated with a part of said costume.

13. The apparatus of claim 10 wherein said finger switch means comprises two pieces of elongated spring steel, separated by two pieces of insulated material at either end, said pieces of spring steel capable of making shorting contact in the central region of said finger switch means.

14. Finger switch means for making shorting contact comprising two pieces of elongated spring steel, separated by two pieces of insulating material at either end, said pieces of steel capable of making said shorting contact in the central region of said finger switch means.

15. The finger switch means of claim 14 wherein said insulated material comprises fiberglass spacer.

16. A switching glove assembly comprising a glove and containing at least one finger switch means, said finger switch means comprising two pieces of elongated spring steel, separated by two pieces of insulated material at either end, said pieces of steel capable of making shorting contact in the central region of said finger switch means.

17. The assembly of claim 16 comprising a plurality of finger switch means.
