Abstract
An athletic performance evaluation device utilizes ultrasonic sensing circuitry or infrared sensing circuitry, a vibration sensitive switch, and an audio input to signal a microprocessor to start a timing function that calculates therefrom an objective evaluation of the athlete's performance. A light emitting diode (LED) may be included in the apparatus to signal the athlete to begin performance while simultaneously starting the timing function. The vibration sensitive switch may be placed on the ground adjacent to a selected position on which the athlete stands to stop the timing function. In operation, the athlete jumps and the ultrasonic sensor signals the microprocessor to begin the timing function and the vibration sensor sends a second signal to stop the timing function when the athlete lands again. The interval between signals is used in distance formula h=g(I/2).sup.2 /2 to determine the height attained and a display is provided for a human sensible output to show the athlete or evaluation personnel the height of the jump. The measurement is based solely on time; thus, each jumper is equally evaluated. In a response-time measurement mode, an audible input to a microphone signals the microprocessor to being the measurement and is simultaneously heard by the athlete. Ultrasonic sensing circuitry adjacent to a selected finishing position signals the microprocessor when the athletes passes through an ultrasonic beam. Alternatively, the LED may signal the athlete to begin performance which simultaneously starts the timing function. In the audible input mode, the microprocessor compensates for the delay in time required for the audible signal to reach the athlete. Various types of sensors are anticipated in the device to start and stop the timing function.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
