Abstract
Official abstract text for this publication.
A system has a boundary conductor unit, which is intended to emit a boundary signal, and an at least partially independent mobile unit, which is intended to detect a boundary provided by the boundary conductor unit by means of cross-correlation. It is proposed that the mobile unit has at least one receiving unit which is intended to receive data transmitted by means of the boundary signal.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system comprising: a boundary conductor unit configured to emit a boundary signal; and an at least partially independent mobile unit configured to detect a boundary provided by the boundary conductor unit, wherein the mobile unit includes at least one receiving unit configured to receive a data transmission with reference to the boundary signal; and a computing unit operatively connected to the receiving unit, the computing unit being configured to: generate at least a first correlation bit pattern and a second correlation bit pattern; perform a first cross-correlation evaluation of the first correlation bit pattern with another correlation bit pattern received in the boundary signal; perform a second cross-correlation evaluation of the second correlation bit pattern with the other correlation bit pattern received in the boundary signal; and allocate an operating mode to the first correlation bit pattern and a command to the second correlation bit pattern. 2. The system as claimed in claim 1 , wherein the boundary signal emitted by the boundary conductor unit is a pseudorandom signal. 3. The system as claimed in claim 1 wherein the boundary conductor unit includes at least one boundary conductor, which forms at least one conductor loop. 4. The system as claimed in claim 1 , wherein the at least one receiving unit is configured to detect an inductive component of the boundary signal. 5. The system as claimed in claim 1 , wherein the computing unit is configured to detect a command transmitted by at least two different phase angles of the correlation bit pattern of the boundary signal. 6. A method comprising: emitting a boundary signal with at least one boundary conductor unit during an operation; transmitting data encoded in the boundary signal between the boundary conductor unit and the mobile unit; and generating with a computing device in the mobile unit at least a first correlation bit pattern and a second correlation bit pattern; performing with the computing device in the mobile unit a first cross-correlation evaluation of the first correlation bit pattern with another correlation bit pattern received in the boundary signal; performing with the computing device in the mobile unit a second cross-correlation evaluation of the second correlation bit pattern with the other correlation bit pattern received in the boundary signal; and allocating with the computing device in the mobile unit an operating mode to the first correlation bit pattern and a command to the second correlation bit pattern. 7. A system comprising: a boundary conductor unit configured to emit a boundary signal; and an at least partially independent mobile unit configured to detect a boundary provided by the boundary conductor unit, wherein the mobile unit includes at least one receiving unit configured to receive a data transmission with reference to the boundary signal; and a computing unit operatively connected to the receiving unit, the computing unit being configured to: generate a correlation bit pattern; perform a cross-correlation evaluation of the correlation bit pattern with another correlation bit pattern received in the boundary signal; and detect a command transmitted by at least two different phase angles of the correlation bit pattern of the boundary signal.
