Device for remote location of an object and method for operating the device
First Claim
1. A method for operating a locating device for remote location of an object, where the locating device comprises a mobile communication unit and is arranged to be placed together with the object, where data concerning the communication unit'"'"'s position are determined and registered by means of existing infrastructure in a cellular network of which the communication unit forms a part when it is activated, and where the communication unit can be activated to a standby mode and deactivated to a sleep mode, characterized in thatthe communication unit is activated and deactivated depending on a time-variable signal, generated in the locating device, thus reducing the communication unit'"'"'s average power consumption, the time-variable signal is influenced by the locating device'"'"'s acceleration, the communication unit is activated when the said signal indicates that the acceleration exceeds a first threshold value, or when the signal indicates that the acceleration has been less than a second threshold value in a first period, preferably in the range 1 to 30 minutes, and that the said threshold values and/or periods can be altered as a response to a message received by the communication unit.

Abstract
The invention relates to a locating device for remote location of an object, and a method for operating the locating device, particularly with a view to recovering objects which are stolen. The locating device comprises a mobile communication unit which is placed together with the object. Data concerning the communication unit'"'"'s position are determined and registered by means of the existing infrastructure in a cellular network of which the communication unit forms a part when it is activated. The communication unit can be activated to a standby mode and deactivated to a sleep mode. The invention is characterized in that the communication unit is activated and deactivated depending on a time-variable signal generated in the locating device, thus providing a reduction in the communication unit'"'"'s average power consumption. The signal is preferably derived from the locating device'"'"'s acceleration.

5. A locating device for remote location of an object, comprising a mobile communication unit and arranged to be placed together with the object, where data concerning the communication unit'"'"'s position are determined and registered by means of existing infrastructure in a cellular network of which the communication unit forms a part when it is activated, characterized in that it comprises
an activation device, comprising a processor device, for activating and deactivating the mobile communication unit depending on a time-variable signal, thus reducing the communication unit'"'"'s average power consumption, a signal device which generates the said signal, comprising a sensor device for measuring the locating device'"'"'s acceleration, where the processor device is arranged to activate the mobile communication unit when the said signal indicates that the acceleration exceeds a first threshold value, or when the signal indicates that the acceleration has been less than a second threshold value in a first period, preferably in the range 1 to 30 minutes, and where the processor device is arranged to alter the said threshold values and/or periods as a response to a message received by the communication unit.
