Abstract

A system and method for finding an object at distance, the system having a parent device (1) and at least one child device (2, 3, 4) that is attachable to or integratable into the object, wherein the parent device (1) and the child device (2, 3, 4) are adapted to communicate over a distance. In order to provide a better adaptability, in particular with respect to a selection of objects that shall be kept track of and combined with an improved object detectability, the invention suggests that the child device (2, 3, 4) has an identity memory (11) storing at least one identity code and the parent device (1) has an identity reader (10) for reading the identity code from the child device (2, 3, 4), an object memory (9) for storing the identity code, an object learner (5) configured with logic (7) to store the identity code in the object memory (9), and an object finder (6) configured with logic (8) to send a search signal to the child device (2, 3, 4) based on the identity code.

Claims

1. A system for finding an object at distance comprising a parent device and at least one child device that is attachable to or integratable into the object, wherein the parent device and the child device are adapted to communicate over a distance,

wherein the child device comprises an identity memory storing at least one identity code that is unique with respect to the identity code of other child devices, and the parent device comprises an identity reader for reading the identity code from the child device,

an object memory for storing the identity code read via the identity reader, an object learner configured with logic to store the identity code in the object memory based on the identity code reading of the identity reader, and an object finder configured with logic to send a search signal to the child device based on the identity code stored in the object memory;

wherein the identity memory is comprised in a near-field-communication sender and the identity reader is comprised in a near-field-communication reader,

wherein the object finder comprises a wireless and/or mobile communication system comprising at least one of a bluetooth communication system, a Wi-Fi-communication system, and a mobile communication system for sending the search signal to the child device, and

wherein the parent device comprises a user interface that is operable for entering at least the following user commands;

a remember command for instructing the object learner to read and store an identity code of a child device in the object memory; and

a finding command for instructing the object finder to send a search signal to the child device.

2. The system according to claim 1, wherein the object finder is configured to use the identity code stored in the object memory to setup a unique connection between the parent device and the child device via the wireless and/or mobile communication system.

3. The system according to claim 1, wherein the object finder comprises multiple wireless and/or mobile communication systems.

4. The system according to claim 3, wherein the object finder is configured to activate each of the multiple wireless and/or mobile communication systems subsequent to one another.

5. The system according to claim 4, wherein the object finder is configured to subsequently activate the multiple wireless and/or mobile communication systems starting from the communication system with the lowest covering range to the communication system with the highest covering range.

6. The system according to claim 3, wherein the child device comprises an alert generator that is configured to be activated after receiving of the search signal, wherein the alert generator is configured to be activated when the finding signal of a bluetooth communication system has been received by the child device.

7. The system according to claim 3, wherein said multiple wireless and/or mobile communication systems comprise a bluetooth communication system, and/or a Wi-Fi-communication system and/or a mobile communication system.

8. The system according to claim 1, wherein the child device comprises an alert generator that is configured to be activated after receiving of the search signal.

9. The system according to claim 8, wherein the child device comprises a signal returner that is configured to transmit a finding signal to the parent device after receiving of the search signal and the alert generator is configured to be activated when the distance between the parent device and the child device is below a threshold distance and/or the signal returner is configured to transmit the finding signal when said distance is above said threshold distance.

10. The system according to claim 8, wherein the alert generator is a sound generator and/or a light generator and/or a vibration generator.

11. The system according to claim 1, wherein the child device comprises a signal returner that is configured to transmit a finding signal to the parent device after receiving of the search signal.

12. The system according to claim 11, wherein the finding signal comprises information about the location of the child device.

13. The system according to claim 1, wherein the user interface comprises a map for indicating the location of the child device.

14. A method for finding an object at distance, in an object finding system according claim 1, comprising the steps of:

providing the object with a child device containing a unique identity code;

reading the identity code from the child device by a parent device and storing the identity code in an object memory of the parent device; and

reading the identity code of the object from the object memory of the parent device and sending a search signal to the child device based on the identity code.

15. A system for finding an object at distance comprising a parent device and at least one child device that is attachable to or integratable into the object, wherein the parent device and the child device are adapted to communicate over a distance,

wherein the child device comprises an identity memory storing at least one identity code that is unique with respect to the identity code of other child devices, and the parent device comprises an identity reader for reading the identity code from the child device,

an object memory for storing the identity code read via the identity reader, an object learner configured with logic to store the identity code in the object memory based on the identity code reading of the identity reader, and an object finder configured with logic to send a search signal to the child device based on the identity code stored in the object memory;

wherein the object finder comprises multiple wireless and/or mobile communication systems for sending the search signal to the child device; and

wherein the child device comprises an alert generator that is configured to be activated after receiving of the search signal,

wherein the child device comprises a signal returner that is configured to transmit a finding signal to the parent device after receiving of the search signal,

wherein the alert generator is configured to be activated when the finding signal of one of the wireless and/or mobile communication systems has been received by the child device, and

wherein the signal returner is configured to transmit the finding signal when the finding signal of another of the wireless and/or mobile communication systems has been received by the child device.
