BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a dummy which resembles a normal sized human being and which is constructed to register blows that are inflicted on the dummy.
2. Description of the Related Art
Tendencies towards violence have increased in society in recent years. This tendency affects all types of persons, both young and old. It has also become more common for those who exercise violence against others to be relatively young.
The violence shown in films, television and above all in video films has become more and more pronounced, as have also the snapshot portrayals of war throughout the world. This has led to the natural, inherent "stop mechanism" against exercising violence on other persons being considerably blunted in many people.
For instance, a person who kicks another person in the head or hits a person with an iron pipe wrapped in cloth in the belief that the person concerned will only lose consciousness without being seriously injured must be unaware of the relationship between the blow and the injury that can be caused as a result thereof.
Consequently, there is a need to be able to demonstrate the types of injury that a given blow can cause. Such demonstrations could be given in schools, within youth organizations, in conjunction with the training of policemen, defense personnel and guards, and also in the education of nursing and health care personnel. One object in this regard may be to exhibit violence for an anti-violence purpose. Another object, for instance, may be to train police in the handling of a baton without causing unnecessary injuries.
The present invention satisfies this need.
SUMMARY OF THE INVENTION
The present invention thus relates to a dummy which is constructed to register blows inflicted on the dummy and which is provided with one or more sensors at that location or those locations on the dummy where blows inflicted thereon shall be registered, the sensors being intended to deliver an electric signal to a computer, wherein the dummy is characterized in that the sensor includes a pressure sensor which is intended to deliver an electric signal which corresponds to the pressure generated in the sensor as a result of a blow inflicted thereon; in that the surface of the sensor that extends parallel with the dummy surface on which the sensor is attached is divided into two or more sections and in that each section is adapted to deliver an electric signal when a blow strikes the section concerned.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention will now be described in more detail partly with reference to an exemplifying embodiment thereof shown on the accompanying drawing, in which
FIG. 1 is a front view of a dummy;
FIG. 2 is a cross-sectional view of a sensor with the various components separated for the sake of clarity;
FIG. 3 illustrates a membrane switch from above;
FIG. 4 is a pressure-time curve; and
FIG. 5 is a block schematic.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 illustrates schematically a dummy constructed in accordance with the invention. The dummy has the same size as a human being. The dummy may be of any kind whatsoever, and may, for instance, be of the same kind as a tailor's dummy. It is important, however, that the dummy is constructed to withstand heavy blows that are delivered with such power as to cause a person who received such blows to be inflicted very serious injury or suffer death.
The dummy 1 is constructed to register blows inflicted on the dummy. To this end, the dummy is provided with one or more impact sensors 3 on that location or those locations on the dummy at which blows inflicted thereon shall be registered, these impact sensors being adapted to deliver an electric signal to a signal processor 2 (see FIG. 5). The body locations in question are primarily the head, the chest, the stomach, the upper arms and forearms, and the thighs and lower parts of the legs. Naturally, impact sensors 3 can also be placed at other locations in accordance with the type of violenc
