Abstract

In an object finding method for finding an object (20) provided with a contactless readable data carrier (2), descriptive data (INF) stored in the data carrier (2) are transmitted to a reading device (1) when the data carrier (2) comes into the effective area of the reading device (1). In the reading device (1) the descriptive data (INF) received from the data carrier (2) are compared with predefined profile data (PRO) in respect of the fulfillment of at least one comparison condition. Upon fulfillment of the comparison condition the reading device (1) subsequently issues a notification (TRIG).

Claims

1. Object finding method for finding an object provided with a contactless readable data carrier, wherein descriptive data stored in the data carrier are sent to a reading device when the data carrier is in the effective area of the reading device, wherein the descriptive data received from the data carrier are compared with predefined profile data in respect of the fulfillment of at least one comparison condition, and wherein the reading device issues a notification upon fulfillment of said comparison condition, wherein the reading device upon reception of descriptive data fulfilling the comparison condition from a number of data carriers displays a hit list of these objects and wherein an object can be selected from the hit list to which a search can be restricted using the reading device to find the selected object from the objects in the hit list, wherein the search comprises automatically reducing the effective area of the reading device to facilitate a restricted search for the selected object.

2. Object finding method as claimed in claim 1, wherein the notification comprises showing at least a part of the descriptive data on a display.

3. Object finding method as claimed in claim 1, wherein at least a part of additional data that are transmitted by the data carrier to the reading device are shown on a display of the reading device.

4. Object finding method as claimed in claim 1, wherein the comparing of the descriptive data with the profile data is done on the basis of character sequences without taking any data structures into consideration.

5. Object finding method as claimed in claim 1, wherein the comparing of the descriptive data with the profile data is done on the basis of character sequences contained in selectable data structure elements.

6. Object finding method as claimed in claim 1, wherein the effective area of the reading device has a main effective direction.

7. Mobile reading device for finding an object provided with a contactless readable data carrier, wherein the reading device is designed for reading out descriptive data that are stored in the data carrier when the data carrier is in the effective area of the reading device, wherein the reading device is designed for the purpose of comparing the descriptive data received from the data carrier with predefined profile data in respect of the fulfillment of at least one comparison condition, and wherein the reading device is designed for issuing a notification upon fulfillment of the comparison condition, wherein the reading device is configured to display, upon reception of the descriptive data, fulfilling the comparison condition from a multiplicity of data carriers, a hit list of these objects in which an object can be selected from the hit list through a user interface to which a search can be restricted using the reading device to find the selected object from the objects in the hit list, wherein the search comprises automatically reducing the effective area of the reading device to facilitate a restricted search for the selected object.

8. Reading device as claimed in claim 7, wherein the reading device has a display and is configured to show as a notification at least a part of the descriptive data on the display.

9. Reading device as claimed in claim 7, wherein the reading device has a display and is configured to display at least a part of additional data that are transmitted by the data carrier to the reading device.

10. Reading device as claimed in claim 7, wherein the reading device is configured to carry out a comparison of the descriptive data with the profile data on the basis of character sequences without taking any data structures into consideration.

11. Reading device as claimed in claim 7, wherein the reading device is configured to carry out a comparison of the descriptive data with the profile data on the basis of character sequences contained in selectable data structure elements.

12. Reading device as claimed in claim 7, wherein the effective area of the reading device has a main effective direction.

13. Object finding system, with a mobile reading device and a multiplicity of contactless readable data carriers that can be attached to objects, wherein descriptive data describing the objects and, optionally, additional data can be stored in the data carriers, wherein the data carriers are designed for the purpose of transmitting the descriptive data and, optionally, additional data to the reading device when the data carriers is in the effective area of the reading device, wherein the reading device is designed for the purpose of comparing the descriptive data received from the data carriers with predefined profile data in respect of the fulfillment of at least one comparison condition, and wherein the reading device is designed for issuing a signal upon fulfillment of the comparison condition, wherein the reading device is configured to display, upon reception of the descriptive data, fulfilling the comparison condition from a multiplicity of data carriers, a hit list of these objects in which an object can be selected from the hit list through a user interface to which a search can be restricted using the reading device to find the selected object from the objects in the hit list, wherein the search comprises automatically reducing the effective area of the reading device to facilitate a restricted search for the selected object.
