Methods and devices for protecting an article against theft
First Claim
1. Method for protecting a commercial product against theft, in which a security unit has a monitoring mode in which theft protection is active such that a theft attempt will cause the security unit to switch to an alarm mode in which at least one of an acoustic and optical alarm is activated, the method comprising:
- deactivating, in the monitoring mode, a receiver housed in the security unit outside of the commercial product; and
activating the receiver when the security unit is shifted to the alarm mode, wherein the security unit has an on-state mode in which the receiver is activated and wherein the security unit is shifted from the on-state mode to a connect mode in which theft protection is not active when the receiver receives a signal from the transmitter, wherein, in the connect mode, the security unit is prepared for a shift to the monitoring mode, and wherein the security unit is shifted from the connect mode to the alarm mode if the security unit is not prepared within a preset time interval for a shift to the monitoring mode.

Abstract
The invention relates to methods and devices for protecting an article against theft. Once a protection element is in the on-position (100), a selection signal is transmitted from an emitter to a receiver provided in the protection element, in order to associate the protection element with the emitter and to shift said protection element into a connection mode (110). The receiver is then deactivated (111) in the connection mode (110). The deactivation (111) of the receiver reduces the energy consumption of the protection element, and prevents the protection element from unintentionally receiving other selection signals. Once the protection element has been shifted (112) into an alarm state (120), for example, due to an attempted theft, the receiver thereof is reactivated, in order to reauthorize the reception of a selection signal. The alarm state (120) can be terminated (123) by one such selection signal.

12. Method for protecting a commercial product against theft, in which a security unit is connected to a central unit via connectors, and in which the central unit has a monitoring mode, in which theft protection is active such that a theft attempt will result in a shift to an alarm mode in which at least one of an acoustic and an optical alarm is activated, the method comprising:
-
deactivating, in the monitoring mode, a receiver that is housed in the central unit outside of the commercial product; and activating the receiver when the central unit is shifted to the alarm mode, wherein the central unit has an on-state mode, in which the receiver is activated and wherein the system is shifted from the on-state mode to a connect mode in which theft protection is not active when the receiver receives a signal from a transmitter, wherein at least one of the security unit and the central unit are prepared in the connect mode for a transfer to the monitoring mode, and wherein the central unit is shifted from the connect mode to the alarm mode if at least one of the security unit and the central unit have not been prepared within a preset time interval for a shift to the monitoring mode. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 26, 27)

25. Method for protecting a commercial product against theft, in which a security unit is connected to a central unit via connectors, and in which the central unit has a monitoring mode, in which theft protection is active such that a theft attempt will result in a shift to an alarm mode in which at least one of an acoustic and an optical alarm is activated, the method comprising:
-
deactivating, in the monitoring mode, a receiver that is housed in the central unit outside of the commercial product; and activating the receiver when the central unit is shifted to the alarm mode, wherein a transmitter transmits a selection signal that is used to control at least one of termination the alarm mode and shift the security unit to a connect mode in which theft protection is not activated, the selection signal being received by the receiver, and wherein the security unit has an on-state mode in which the receiver is activated and wherein the alarm mode is not terminated if the selection signal received during the alarm mode differs from another selection signal received by the security unit in the on-state mode.

Method for protecting a commercial product against theft, in which a security unit is connected to a central unit via connectors, and in which the central unit has a monitoring mode, in which theft protection is active such that a theft attempt will result in a shift to an alarm mode in which at least one of an acoustic and an optical alarm is activated, the method comprising:
-
deactivating, in the monitoring mode, a receiver that is housed in the central unit outside of the commercial product; and activating the receiver when the central unit is shifted to the alarm mode, wherein a transmitter transmits a selection signal that is used to control at least one of termination the alarm mode and shift the security unit to a connect mode in which theft protection is not activated, the selection signal being received by the receiver, and wherein the security unit and the central unit are switched off and on in series to transfer a selection signal to the security unit and the central unit, respectively.
