FR2781357A1 - Equipment for testing speed of reflexes, comprises short rod for supporting target object, hand rest, unipolar contacts and electronic circuits which include starting buzzer and indicating lamps. - Google Patents

Abstract

Two players use boards (3) which have short rods (1) to support target objects and a starting hand position. Electrical contacts (2,4) are linked to the short rod (1) and starting hand position and connected to relay and contact circuits which use novel methods for controlling gate outputs and providing time delay. The electrical circuits include a starting buzzer and lamps which indicate the winning player

Description

I

THE REFLEXMETER

  The present invention relates to a device which makes it possible to test the reflexes of two individuals. This device is

  presented in the form of a game, but the field of use

  tion remains very open. It is a new process, no com-

  Parison cannot therefore be made. If you put an object on a table and, in a

  sort of duel, two people try to grab it fast-

  there is little chance that they will be able to avoid the shock

with their hands.

  I0 The device according to the invention claims to provide a remedy

to this disadvantage.

  According to a first characteristic, it comprises two identical supports (3) and (3 ') in which are inserted con4ae

  unipolar and one-way tacts (or switches).

  According to a second characteristic, it comprises two identical objects in the form of sticks (1) and (I ') that a hand

can catch easily.

  According to a third characteristic, it has a part

  electronics essential for this achievement.

  The accompanying drawings and diagrams illustrate the invention:

  Figure I represents a perspective of the whole object-

  support (1,3) (possibly I ', 3'), and their arrangement.

  Figure 2 shows a section of the support alone, which shows the contacts inserted therein; (2) and (4), (possibly, 2 ', 4'). The two sets being identical,

  one representation was sufficient.

  FIG. 3 represents the relay electrical diagram which is

  ra at the base of the electronic circuit of the invention.

  FIG. 4 represents a new method of setting the inputs of the electronic doors to one or zero (ex: NAND with two inputs), allowing, for this purpose, the use of one-way switches (ex: a) instead of those two branch

used.

  The inputs are kept at one by means of a resistance (R) calculated for this purpose. We therefore have zero on exit, which corresponds well to open. If we close a, we bring the inputs to zero and the output goes to one; this body responds well to a closed. So we get a output and its

  additional input; and this without any electrical interruption

  as an input when handling a, which further eliminates the risk of interference. It's this news

  method which will be used for the invention.

  Figure 5 shows another section of the electro-

  nique of the invention presented in the form of a box with an input (E) and two outputs (aI, 52). It mentions a timing system using NAND gates

  (&) with two entries in association, particular, with a tran-

  NPN type sistor. If the input (E) is brought to one, the tran-

  sistor T, with its base F3, hangs. The capacitor C will charge through MI. After a certain time, point B will have reached a sufficient voltage to switch the outputs; SI will go to one, and 52 will go to zero. If we

  branch on SI or S2, we will get a delay either at the farm-

  ture either at the opening. If the input (E) is brought to zero, the transistor turns on, the capacitor C discharges there via R2. Point B will be immediately

  brought to zero. This will cause, again, toggle

  ler outputs * Study of operation With reference to figures, I, 2,3:

  On support 3, the positioning of the object and the position-

  hand, will be conditioned by contacts a or

  (2) and d or (4). On 3 'we will have, b or (2') and (c) or (4 ').

Referring to Figure 13:

  - x, y, z = relay contacts X, Y, Z.

  - t = contact of the relay. timed T,

  - m = push button (cycle trigger).

  - LI, L2 = indicator lights (results).

- S = bell.

  - The line found on some contacts reads barre,

  (a): this means complement of (a).

  For the cycle to start correctly, it is necessary to

  ment that the objects are in place and that the hands are a position on their respective support. Placing objects has the effect of opening contacts a and b, while

  the positioning of the hands has the effect of closing the con-

  tacts d and c. When these conditions are met, the cycle is started with a pulse on m. Therefore, the relay X is activated and the time delay relay T requested. After a certain time, the buzzer 5 will start up due to the activation of T. It is only from this moment that the two

  players, in a merciless duel, will have to take full-

  without dropping it from the object placed in front of them. Also

  as soon as the act is carried out, an indicator light (LI or L2) will light up to designate the fastest and winner. The winner's light will remain on until the cycle is restarted

  under the same conditions as before.

  However, if one of the two players tried any ace action before the ring signal, by releasing c or d, it is

  the light assigned to. the adversary who would light up. The con-

  tacts c and d having the role of allowing a departure in the

  rules by prohibiting any action before the ring signal

  laughs. We start over the game always under the same conditions.
