Abstract
Abstract The aimed launching of projectiles is simulated by means of an electroacoustic transducer which is energized to emit a beam of sound waves, preferably at ultrasonic frequency. A cooperating target also employs an electroacoustic transducer and apparatus for indicating reception of the sound beam by that transducer. The emitter transducer may be mounted in a simulated firearm, or other projectile launcher, while the receiver transducer may be mounted on a simulated target.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
124 words
A system of simulating the firing and trajectory of a projectile comprising: a. a portable apparatus for simulating the launching of a single projectile at a time having means for visually aiming said apparatus and means for producing a narrowly dispersed aimable beam of sound waves in a predetermined frequency range, said beam simulating the substantially straight trajectory of said single projectile in response to the manual orientation and actuation of said launcher by an operator, and b. target means mounted separately from said launcher and being constructed to respond primarily to impingement thereupon of said aimed beam, said means being substantially non-responsive to sound waves outside said predetermined frequency range, said target means also including means for producing an indication when it responds.
Claim 2
Independent Claim
124 words
A system of simulating the firing and trajectory of a projectile comprising: a. a portable apparatus for simulating the launching of a single projectile at a time having means for visually aiming said apparatus and means for producing a narrowly dispersed aimable beam of sound waves in a predetermined frequency range, said beam simulating the substantially straight trajectory of said single projectile in response to the manual orientation and actuation of said launcher by an operator, and b. target means mounted separately from said launcher and being constructed to respond primarily to impingement thereupon of said aimed beam, said means being substantially non-responsive to sound waves outside said predetermined frequency range, said target means also including means for producing an indication when it responds.
Claim 3
Dependent Claim
30 words
The system according to claim 1 wherein said launcher emits said beam as a pulse having a predetermined duration only in response to a corresponding manual operation by said operator.
Claim 4
Dependent Claim
20 words
The system according to claim 2 wherein said indication has a duration longer than the duration of said emitted pulse.
Claim 5
Dependent Claim
24 words
The system according to claim 3 wherein said indication ceases at a predetermined time after the cessation of the detection of said emitted pulse.
Claim 6
Dependent Claim
35 words
The apparatus of claim 1 wherein said sound wave beam emitting means comprises a piezoelectric transducer, means for electronically exciting said transducer, and means for forming the sound waves from said transducer into said beam.
Claim 7
Dependent Claim
45 words
The apparatus of claim 5, wherein said target means comprises a second piezoelectric transducer adapted to be exposed to said sound waves, means for detecting the electrical signals produced by said second transducer in response to said sound waves, and means for indicating said detection.
Claim 8
Dependent Claim
11 words
The system according to claim 1 wherein said sound is ultrasonic.
Claim 9
Dependent Claim
13 words
The system according to claim 1 wherein said indication is a visible indication.
Claim 10
Dependent Claim
13 words
The system according to claim 1 wherein said indication is an audible indication.
Claim 11
Dependent Claim
22 words
The system according to claim 1 wherein said target means produces said indication only when said detected pulse has a predetermined duration.
Claim 12
Dependent Claim
29 words
The system according to claim 1 wherein said target means comprises directional means for limiting the response thereof to the impingement of said beam thereupon only at predetermined angles.
Claim 13
Independent Claim
136 words
A system of simulating the firing and trajectory of a projectile comprising: a. a portable apparatus for simulating the launching of a single projectile at a time in the form of a toy fire-arm having a barrel which emits an aimable beam of sound waves in a predetermined frequency range, said barrel having mounted therein a piezoelectric transducer, means for electronically exciting said transducer and means for forming the sound waves from said transducer into said beam, said launching apparatus being manually orientable and actuatable by an operator, and b. target means mounted separately from said launcher and being constructed to respond primarily to impingement thereupon of said aimed beam, said means being substantially non-responsive to sound waves outside said predetermined frequency range, said target means also including means for producing an indication when it responds.
Claim 14
Independent Claim
136 words
A system of simulating the firing and trajectory of a projectile comprising: a. a portable apparatus for simulating the launching of a single projectile at a time in the form of a toy fire-arm having a barrel which emits an aimable beam of sound waves in a predetermined frequency range, said barrel having mounted therein a piezoelectric transducer, means for electronically exciting said transducer and means for forming the sound waves from said transducer into said beam, said launching apparatus being manually orientable and actuatable by an operator, and b. target means mounted separately from said launcher and being constructed to respond primarily to impingement thereupon of said aimed beam, said means being substantially non-responsive to sound waves outside said predetermined frequency range, said target means also including means for producing an indication when it responds.
Claim 15
Independent Claim
106 words
A system for simulating the firing and trajectory of a projectile comprising: a. a portable simulated projectile launcher which emits and aimable beam of sound waves in a predetermined frequency range in response to the manual orientation and actuation of said launcher by an operator, said launcher also including adjustable means for varying the dimensions of said beam, and b. target means mounted separately from said launcher and being constructed to respond primarily to impingement thereupon of said aimed beam, said means being substantially non-responsive to sound waves outside said predetermined frequency range, said target means also including means for producing an indication when it responds.
Claim 16
Independent Claim
