FR2963462A1 - Electric timing device for use by athletic trainers during training of analysis of athletic runners, has radio emitter sending departure code to chronometer or to display to start incrementation to specific second when flash is emitted - Google Patents

Abstract

The device has a microcontroller whose output is connected to a departure coder on a negative power supply that passes from high state to low state, where vocal commands recorded in EPROM are sent by the microcontroller through an audio transformation circuit to audio amplifiers that activate loud speakers and an observed athlete. A departure code is sent by the radio emitter to a chronometer or to the display to start the incrementation to one-thousandth of second when a flash is emitted.

Description

ELECTRONIC TIMING SYSTEM FOR TRAINING FOOT RACES.

BACKGROUND OF THE INVENTION In the training of speed or endurance the coaches are confronted with several problems - the chronos of the athlete are always different from his times in the training, he thinks himself always faster because of the inaccuracy of the manual chrono - false starts are no longer tolerated, only one is eliminatory - discrimination against the middle distance at the chronometry level (the tools are rare) - the tools to evaluate the reaction times of the sprinters are as rare as expensive - you always have to wait for a big competition to know a certain value of the athlete, because it is only during this time that the timing is electric, 45 that the speed of the wind is measured, that the gun is used for the initially, that sometimes the reaction times are displayed. - for athletes in third world countries, the situation is dramatic, indeed the bottom The departures are always given either by a whistle, or a clapper au? o sound dubious, or by a clap of the hands, or by shouts of the coach, and the time is manual. In this context, athletes from rich countries are favored at the level of training and consequently at the chronometric level. Poor countries spend enormous sums to upgrade their athletes through 25 training courses and competitions in the distance. The new system relieves everyone and puts all the athletes of the world on the same footing because it allows a precise electrical timing at 1 / 100th of a second (IAAF standard) 3o - a start to the sound of the gun - a electric timing of the middle distance - a calculation and display of reaction times at the II1000th of a second - a possibility for the athlete to train under the right conditions in the absence of the coach - a calculation of the speed launched - a segmentation of the distance run with display of split times - ease of installation and use. - a memory of more than 200 times - a range of 500m to 3 km from the sensors 40 - the system runs on batteries or sector - a USB connection to the computer to save the data of the training

45 -The start is given either by the coach (audio start) fig3, or by the autonomous start box (fig4) -The stopwatch (fig6 or fig 2) is stopped at the moment the athlete crosses the infrared barrier. (figl) -The time or times are displayed on the screen (fig2-18) of the portable stopwatch. 50 There is possibility of storing times. A wireless printer can print all chrono memory if desired. - a USB connection to a pc is possible - the range is 500m to 3km. 1-The 'sprint mode'

A Mode with coach The coach gives the audio commands to the athlete. The trainer has a wireless microphone incorporated in the system. It may be at a very remote distance. The athlete obeys the commands, as soon as he starts his race his reaction time is displayed on the chrono screen (fig2). When crossing the barrier or the infra red barriers his running time (or his times) is (are) displayed on the stopwatch screen (fig2) (18). B Mode without coach The athlete presses a button (fig4) (38) on the starting box, he has one minute to get behind the starking blocks. The box of departure (fig 4) gives him the audio commands of the type: "to your 45 marks! " " Ready ? Then a gun sound recorded in the box told him to leave. Orders can be given in 10 languages or more and can be customized. His reaction time is displayed on the timer (fig2), his race times also 20 when he crosses the infrared barrier (s) (fig1).

C Speed mode launched - The athlete puts as many infra red barriers as he deems necessary. (Figl) - As soon as he crosses the first barrier the chrono is activated. 25 -At the passage of each barrier the time is displayed on the chrono screen (fig2) (18)

Distance mode "Distance mode example 800 M) With or without a coach (see Sprint mode) -The athlete is placed behind the starting line 30 -The coach gives him the vocal start according to the distance, activates the capture key (fig2 ) (20) or not. Example: The coach may want the lap times after 5 laps or whatever. -If the athlete is alone, he can use the starting box (fig4). The athlete has a display (FIG. 6) (57) with digits 10 cm high to monitor the passage time of each interval.
