Retail item management using wireless sensor networks
First Claim
1. A system for identifying handling events of an item, the system comprising:
- at least one wireless sensor node, WSN, tag associable with the item, the WSN tag comprising;
a transceiver;
at least one sensor, the at least one sensor configured to generate sensor data based at least in part on motion of the WSN tag;
a memory, the memory configured to store at least one event filter and the sensor data;
a tag processor, the tag processor configured to;
filter the sensor data based on one of the at least one event filters, the one of the at least one event filters defining a plurality of movements and a threshold, each of the plurality of movements having to meet the threshold for the one of the least one event filters to be met;
determine whether an event occurred based on the filtering of the sensor data;
generate event data in response to determining an event occurred; and
cause the transceiver to transmit the event data.

Abstract
A system for identifying handling events of an item is provided. The system includes at least one wireless sensor node, WSN, tag associable with the item. The WSN tag includes a transceiver and at least one sensor. The at least one sensor is configured to generate sensor data based at least in part on motion of the wireless sensor node. The WSN tag includes a memory configured to store at least one event filter and the sensor data. The WSN tag further includes a tag processor that is configured to filter the sensor data based on the at least one event filter. The tag processor is configured to determine whether an event occurred based on the filtering of the sensor data and generate event data in response to determining an event occurred. The tag processor is configured to cause the transceiver to transmit the event data.

5. A method for identifying handling of an item, the method comprising:
-
generating, by a wireless sensor node (WSN) tag, sensor data based at least in part on motion of a wireless sensor node associable with the item; storing, by the WSN tag, at least one event filter and the sensor data; filtering, by WSN tag, the sensor data based on one of the at least one event filters, the one of the at least one event filters defining a plurality of movements and a threshold, each of the plurality of movements having to meet the threshold for the one of the event filters to be met; determining, by the WSN tag, whether an event occurred based on the filtering of the sensor data; generating, by the WSN tag, event data in response to determining the event occurred; and transmitting the event data. - View Dependent Claims (6, 7)
