Method and arrangement to determine whether two objects belong to each other |
| 摘要 |
<p>The two objects [10,11] are signal coupled so long as they are within a specific distance [30] of each other. When the distance becomes too great an alarm is triggered and a signal is emitted. The system may be used with such as keys and briefcases so as to prevent loss.</p> |
