Abstract

Embodiments relate to a transmitter and/or a receiver for a system for detecting an event which is triggered by an object crossing a monitored line. The transmitter is configured to successively transmit data packets independently of an occurrence of the event. The receiver is configured to receive successive data packets independently of the occurrence of the event. Each data packet comprises information on a number of events which occurred up to a transmission time of the data packet, wherein the transmission times of successive data packets are each located in a predetermined transmission time period.

First claim

The invention claimed is:

1. A transmitter for a system for detecting an event corresponding to an object crossing a monitored line,
wherein the transmitter is configured to successively transmit data packets independently of the occurrence of the event,
each data packet comprising a piece of information on a number of events which occurred up to a transmission time of the data packet,
wherein the transmission times of successive data packets are each located in a predetermined transmission time window.

2. The transmitter according to claim 1 , wherein the transmitter is configured to generate the data packets such that each of the data packets comprises a piece of information on the transmission time of the data packet.

3. The transmitter according to claim 1 , wherein the transmitter is configured to generate each of the data packets such that the data packet comprises a piece of information on a radio resource for a subsequent data packet.

4. The transmitter according to claim 3 , wherein the radio resource is a transmission time or a frequency of the subsequent data packet.

5. The transmitter according to claim 1 , wherein the transmitter is configured to generate the data packet such that the data packet comprises a piece of information on an age of the occurred event.

6. The transmitter according to claim 1 , wherein the transmitter is configured to transmit each of the data packets at a random transmission time such that the data packet is transmitted completely within its predetermined transmission time window.

7. The transmitter according to claim 1 ,
wherein the transmitter is configured to transmit the successive data packets by multiplexing using a second transmitter, and the transmitter comprises a receive module which is configured to receive successive data packets of the second transmitter,
wherein each of the data packets of the second transmitter comprises at least one piece of information on a number of second events which occurred up to the transmission time, and
wherein the transmitter is configured to generate the successive data packets such that each data packet comprises a piece of information on the number of second events which occurred up to the transmission time.

8. The transmitter according to claim 1 , wherein the event is a goal which corresponds to a gaming device, in particular a ball or a puck, crossing a monitored goal line.

9. A receiver for a system for detecting an event corresponding to an object crossing a monitored line,
wherein the receiver is configured to receive successive data packets independently of the occurrence of the event,
each of the data packets comprising a piece of information on a number of events which occurred up to a transmission time of the data packet,
wherein the transmission times of successive data packets are each located in a predetermined transmission time window.

10. The receiver according to claim 9 , wherein each of the data packets comprises a piece of information on the transmission time of the data packet.

11. The receiver according to claim 9 , wherein the receiver is configured to output a signal which indicates the event that a currently received data packet comprises a piece of information on a number of occurred events which is higher than a number of occurred events according to a preceding data packet.

12. The receiver according to claim 9 , wherein the receiver is configured to reduce a receive power of a receiver circuit between two successive data packets based on a piece of information on the transmission time of the subsequent data packet within the current data.

13. The receiver according to claim 12 , wherein the receiver is configured to increase the receive power until it receives a subsequent data packet if it does not or not completely receive a data packet within an interval at the transmission time according to a piece of information in a preceding data packet.

14. The receiver according to claim 9 , wherein the receiver is configured to decrease a receive power of a receiver circuit if the receiver does not receive any data packet over a time period which is greater than the predetermined time period.

15. The receiver according to claim 14 , wherein the receiver is configured to increase the receive power of the receiver circuit for a time period which is greater than the transmission time period.

16. The receiver according to claim 9 , wherein the receiver may be worn on a wristband, in particular be integrated into a watch.

17. A method for transmitting data packets for a system for detecting an event corresponding to an object crossing a monitored line, comprising:
generating successive data packets such that each of the data packets comprises a piece of information on a number of events which occurred up to a transmission time of the data packet,
transmitting successive data packets independently of an occurrence of the event such that transmission times of successive data packets are each located in a predetermined transmission time window.

18. A method for transmitting data packets for a system for detecting an event corresponding to an object crossing a monitored line, comprising:
receiving successive data packets independently of the occurrence of the event, whose transmission times are each located in a predetermined transmission time window,
reading out the data packets, wherein each of the data packets comprises a piece of information on a number of events which occurred up to a transmission time of the data packet.
