Aptitude testing machine

Claim 2

Apparatus for testing subjects which comprises a screen, a motion-picture projector mounted to project a motion picture onto said screen, means for measuring the speed of movement of an object advancing toward said screen, and comprising means for generating light beams positioned to be interrupted by said object as it starts toward and as it reaches said screen, pressure-responsive means for measuring the force applied to said screen when said screen is struck by said object, photocells positioned to detect such interruptions, and means for correlating signals derived from said photocells, said pressure-responsive means, and the track of said film to produce and record signals representative of the physical aptitudes utilized in causing said object to strike said target.

Claim 3

Apparatus as claimed in claim 1 further comprising means for producing a signal indicative of the location at which said screen has been struck.

Claim 4

Apparatus as claimed in claim 2 in which said means for producing a location-indicating signal comprises: a first set of light sources positioned to project parallel beams of light in a first direction parallel to and immediately in front of said screen, a second set of light sources positioned to project parallel beams of light in a second direction transverse to said first direction, parallel to and immediately in front of said screen, a first set of photocells positioned at regular intervals to receive the light beams from said first set of light sources, a second set of photocells positioned at regular intervals to receive the light beams from said second set of light sources, individual resistance means for each set of photocells to which the photocells of that set are connected at regular intervals corresponding to the physical distances therebetween, and means actuated whenever at least one photocell is darkened by interruption of the beam received thereby to simultaneously short circuit a predetermined portion of that section of the associated resistance means connected between each darkened photocell and the next, and determine the highest resistance remaining between the connection of any darkened photocell and one end of said resistance.

Claim 5

Apparatus for testing subjects which comprises: a screen, a motion-picture projector mounted to project a motion picture onto said screen, pressure-responsive means for measuring the force applied to the screen when said screen in struck by an object, means for generating light beams positioned to be interrupted by said object as it starts toward and as it reaches said screen, photocells positioned to detect such interruptions, and means electrically connected to said photocells for measuring and indicating the intervals of time elapsing between successive interruptions of said beams by said object as it approaches said screen.

Claim 6

Apparatus for testing subjects which comprises: a screen, a motion-picture projector mounted to project a motion picture onto said screen, pressure-responsive means for measuring the force applied to the screen when said screen in struck by an object, means for generating light beams positioned to be interrupted by said object as it starts toward and as it reaches said screen, photocells positioned to detect such interruptions, and means electrically connected to said photocells for measuring and indicating the intervals of time elapsing between successive interruptions of said beams by said object as it approaches said screen.

Claim 7

Apparatus as claimed in claim 4 in which said means for measuring the force applied to said screen comprise a frame supporting said screen, a plurality of pressure-responsive means connected to said frame for generating signals proportional to the horizontal pressure received, and integrating means for determining the total energy received by said screen.
