Abstract
A method to measure height of a vertical jump of a jumper. At least one switch is deactivated by the jumper stepping thereon. The switch is initially activated by the jumper jumping upward therefrom and thereafter deactivated upon return. A time period is measured while the switch is activated. The square of the activated time period is calculated and thereafter the result is multiplied by a constant to derive vertical jump height. Finally, the resultant vertical jump height of the jump is displayed.
Claims10
A portable vertical jump measuring device, which comprises:
- a plurality of normally open switches wired in parallel, each said switch being adapted to deliver a signal and deactivated in response to a jumper stepping thereon, wherein said switches are embedded in a portable mat;
- a timer connected to said switch and adapted to receive said switch signal to measure a time period said switch is activated while said jumper is in the air;
- means to receive said measured time period and to calculate the square of said activated time period and thereafter multiply the result by a constant to derive vertical jump height;
- and
- an output device connected to said means to display the resultant vertical jump height of said jumper.
A method to measure vertical jump height of a jumper, which method comprises:
- wiring a plurality of normally open switches in parallel and embedding said plurality of switches in a portable mat;
- closing at least one of said plurality of normally open switches by said jumper stepping thereon;
- opening said at least one switch by said jumper jumping therefrom and thereafter closing said switch;
- measuring a time period while said at least one switch is open;
- calculating the square of said open time period and thereafter multiplying the result by a constant to derive vertical jump height;
- and
- displaying the resultant vertical jump height of said jump.
A portable vertical jump measuring device, which comprises:
- a plurality of normally closed switches wired in parallel, each said switch being adapted to deliver a signal and activated in response to a jumper stepping thereon, wherein said switches are embedded in a portable mat;
- a timer connected to said switch and adapted to receive said switch signal to measure a time period said switch is deactivated while said jumper is in the air;
- means to receive said measured time period and to calculate the square of said activated time period and thereafter multiply the result by a constant to derive vertical jump height;
- and
- an output device connected to said means to display the resultant vertical jump height of said jumper.
