88. Measuring Athlete's Speed On An Ice Rink Or A Running Track, etc.
Two infra-red sensors, or one infra-red sensor and one foot switch can be used. Place the
sensors an "x" distant apart. When using the foot switch pad the athlete must stand on the first
switch pad, which is plugged into the left connector jack. The infra-red sensor beam is plugged
into the right connector jack.(use the short interface cable) On the ice rink, use the two IR-
sensors. Plug the first sensor into the left connector jack, and the second sensor into the right
connector jack. (note. If the intercepted beam must reach more then 5 feet, it will be necessary
that a reflector be used on the opposite side of the track). After the first sensor is activated, the
display will record the time that the second sensor is activated. To calculate the speed in
miles/hr, use the following formula: Speed in miles/hr = "x" distance(ft)/time(sec)*(0.6818). The
speed in miles/hr is the spacing between sensors, divided by the displayed time in seconds,
multiplied by the number 0.6818.

89. Additional Ideas For Using Speed-Trac Anticipator
Speed-Trac can be mounted on a wall using the mounting holes on one side. Align Speed-Trac
horizontally while marking the mounting holes with pencil. Hammer small headless nails in line
with the marks. The Speed-Trac can now be easily placed on the nails, and can be removed from
the wall when needed. Mount the "reset/start" button high on a wall. The height will require a
vertical jump with out-stretched hand. The athlete initiates the Speed-Trac by jumping and
striking the "reset/start" button. Immediately the athlete must step back a set distance so that
the complete Speed-Trac is visible. The green light on the trac will flash "on and off"; after a
short delay, the lights will speed across the Speed-Trac. The athlete must now run up to the wall
and jump up to strike the reset/start target button. The goal, is to anticipate when the lights will
reach end of trac, and to stop the light before it returns to the opposite side of the trac. The
display will record the anticipation accuracy. Random speed 5-20 mph ; "pitch" delay 4-7
seconds

90. Visual Memory Using The 4 Light/Switch Boxes
One light will flash "on" signaling trainee to depress this light button. The same light will flash
once again followed immediately by a second light. Trainee must then depress both lights in the
sequence they occurred and then a third light will appear. Trainee must depress the first light,
the second light and the third light in sequence and continues with this sequencing. A point will
