plotters, electronics, etc. to show simultaneous correlation between actual
displacement, velocity, and acceleration. Diagrams and pictures. |
| 9B15.11 | ladder of light | AJP 42(5),409 | Reflect a beam across an air track many times and record the output of a audioamp. |
| 9B15.12 | air track velocity meter | AJP 40(1),202 | A capacitor is charged while a light beam is blocked. |
| 9B15.13 | air track timing circuit | AJP 56(10),950 | A circuit that interfaces five digital stop watches to five gates on the air track. |
| 9B15.14 | mechanical start-stop gates | AJP 48(8),685 | Mechanical gates instead of photogates control relays which in turn can control something else. |
| 9B15.15 | model race track kinematics | AJP 52(3),281 | Twenty optical sensors with an Apple computer interface are attached to a model race track to give successive time intervals. |
| 9B15.15 | distributed infrared detector | AJP 56(8),739 | Forty-six permanently mounted emitter-detector pairs are interfaced to a computer. |
| 9B15.16 | multitimer air track system | AJP 48(1),85 | Photoelectric
sensors combined with solid state memories store a sequence of time intervals
which are then transferred to a digital display. |
| 9B15.16 | multiphotogate timer system | AJP 55(11),1050 | A
multiprocessor based multiphotogate array system that allows the time interval
between any set of gates to be displayed by selecting from a keyboard. |
| 9B15.16 | air track multitimer | AJP 50(4),381 | As
the air cart passes along a tape with holes, a light beam is transmitted
to a photodetector. A circuit is given to store and read out the timing information. |

| 9B15.30 | air track glider position | AJP 53(1),86 | Ferrite
magnets on the air track glider pass by a wire bent into a square wave and
the induced pulses are shaped and then recorded by a microcomputer. |

| 9B15.32 | air track induction speedometer | AJP 41(3),419 | Magnets
mounted on the air cart pass on both sides of a long squarewave shaped copper
wire that goes to an amplifier and oscilloscope. |
| 9B15.35 | air track inductive recorder | AJP 43(4),375 | A container of fine iron particles in suspension on the cart moves past microphones attached to a tape recorder. |
| 9B15.40 | air track timer | AJP 37(3),327 | Circuit for a timer that reads out a voltage proportional to the speed of an object. |
| 9B15.50 | y-t air track recorder | AJP 36(1),61 | A roll of spark paper is used to obtain y-t records of an air track. |
