There has long been a need for a method by which it can is possible to prevent theft of goods, goods or other objects, which are, for example are located in department stores, shops, factories or other premises. To this Various types of monitoring have been used to achieve this goal, for example with the help of television cameras and associated television monitors, or with the help of surveillance personnel, or by means of various types of alarm systems or locking and locking devices.

The invention is based on the object of creating a new method which makes it possible an extremely effective method of monitoring people to achieve the the limited rooms or restricted areas or the like, visit, with each attempt by this procedure a theft is made evident and thus subject to certain actions or acts will. The invention also aims to provide a device with the aid of which this method can be carried out.

This object is achieved according to the invention solved that a weight-indicating arrangement both at the entrance and at the exit of the relevant Premises or the restricted area is provided. When a person receives the entrance If you pass to such a room or such a restricted area, the one provided at the entrance will be used weight-indicating arrangement used to to determine the exact total weight of the person concerned. This total weight is based on suitable means, e.g. on an optically readable punch card, magnetically or electronically readable card, an optically readable, written or printed card or on another, possibly already known information carrier for storing the entered Information. At the exit of the premises or the restricted area, a second, weight-indicating or receiving or registering arrangement provided, which the weight of the relevant Compares the person with the weight previously registered at the entrance. At the exit, For example, at the cash register counter in a supermarket, the previously recorded information carriers are used in a. Reader or the like. entered,

causing a change in the weight of the person having a predetermined and set value exceeds, the activation of suitable control devices, alarm devices or the like. causes, e.g. blocking the exit or causing an audible alarm or a camera is put into operation.

A schematic embodiment of the invention which can be used in a supermarket, is described in more detail below with reference to the drawing.

Fig. 1 shows a plan view of the entrance and the exit of a supermarket, and

FIG. 2 shows a perspective view of that shown in FIG Arrangement.

The embodiment of the invention shown schematically in FIG. 1 is in a supermarket arranged. At an entry barrier or barrier 1, a first weighing mechanism 2 is in or on the

809814/0658

40 27430U

Floor attached. When a person approaches the entrance barrier 1, the weighing mechanism determines the weight of this person, for example by mechanical, electronic or other means. This total weight is registered and recorded, for example with the help of a card-shaped information carrier in a registration device 3. If this information carrier is available for the person at the entrance KxMütnlx, the entrance barrier 1 is opened, whereby the person concerned is allowed access to the premises of the supermarket. If this person decides to leave the relevant premises, a second weighing device 5 comes into operation, which corresponds to the first weighing device 2, but is arranged at the exit, for example at the cash register counter 4. This second weighing device 5 again determines the total weight of the person concerned. By entering the information carrier, for example a card, into a recording and reading device 6, a comparison is made between the total weight of the person when entering and the total weight of the person when leaving the demarcated space, for example with the help of a minicomputer. Provided that the

8098U / 0658 -10-

27430U

Weight of the person when leaving the premises no more than a predetermined value differs from the total weight of the person entering, an exit barrier 7 is opened. But if the weight difference exceeds this predetermined value, various Types of actions can be evoked by noting this weight difference. In Fig. 1, a second exit barrier 8 is shown, which is actuated and in a closed position can be brought, as indicated by dashed lines. Alternatively, an alarm device could be used be put into operation by e.g. the manager or supervisor of the supermarket or alerted any other person; also a camera could be operated to by the concerned Person to take a photograph. The actions that are set in motion when the Difference in weight is excessively high, this can affect the proportions or objects in question be adapted, depending on the type of room or other wishes,

The weighing devices mentioned above 2 and 5 each consist of one on the

Floor provided step plate or the like. Which a mechanical, electronic or other Weighing system influenced. The first weighing device 2 transfers the determined weight a suitable information carrier, e.g. by printing, Hole punching, magnetic application or something else, possibly known per se Method of storing information.

The second weighing device 5 transmits this determined weight on a comparison device, which means for recording, evaluation or Computing the information from the respective information carrier and which further means has to provide an alarm signal or a signal for other monitoring or control devices to be generated when the determined weight difference is greater or less than the predetermined one Limit should be.

This allowable weight difference should be based on the prevailing circumstances be determined, e.g. taking into account temperature conditions; as an example of one appropriate limit could be set at 10 to ^ O g

will. Other registration devices of information on information carriers (the expression "registration" is intended to include all methods known per se for storing information may of course be included) in connection with toilets, restaurants or other premises within the protected area Restricted area can be arranged in which a greater change in weight can be expected as a result of normal activity. Access such special rooms can thus be obtained by the fact that the information carrier is given upon entry and a new information carrier or the like. is obtained which contains the exact weight information when leaving the respective ruins. These Registrations can be made more similar with the help of κ ± Devices are made as described above using the input registration device a supermarket have been described.

The method and the device according to the invention thus basically include two Weighing devices, although in certain cases this number can of course be exceeded.

27430H

One weighing device is arranged so that it takes the weight of the person upon entry notices and the same on an information carrier registered, while the second weighing device is arranged to be with a Comparing device cooperates, which the information from the information carrier regarding of the initial weight and this weight with the weight of the person when leaving the Compares spatiality, further combined with this device, a further device which causes an alarm or other monitoring action if the determined weight difference a certain Value exceeds.

The above description is intended in conjunction with the drawing only xm as an example serve to illustrate the essential idea of the invention and show in which Scope the method and the device according to the invention can be used. Consequently This description is not intended to restrict or limit the nature of the Weighing devices of the information carrier, the

Calculation facilities etc. take place because such devices and means can be varied within the framework of means known per se for such types of equipment.

It should also be emphasized that the weight limits, which an activation of alarm functions cause, according to the invention depending on the present Ratios and conditions can be adjustable, and that this weight limit range can be changed if necessary.

As a further embodiment A within the scope of the invention, each weighing device or weight display device can be connected to a central registration device, in which case a person entering the premises receives a card showing the information on each information carrier or the like. makes stored information accessible. The central registration device makes a registration at any time as well as a record or calculation of whether or not any actions are to be taken. This means that a relatively small computer can be used with a desired one
