CONDITION MONITORING DEVICE
First Claim
1. A monitoring device for mounting to an item to monitor the treatment of the item during handling or storage, and for being powered by a cell, the device comprising a sensor for sensing a condition relating to the treatment of the item, a memory arranged to store sensor data, a communication interface arranged to generate a wireless signal for transmitting the data, and a detector for detecting a predetermined event relating to the condition, and the device having a low power mode and a high power mode, the power consumption of the device being relatively higher in the higher power mode, in which the device is triggered to switch from the low power mode to the high power mode for a finite time period following detection of the predetermined event, and to switch from the high power mode upon expiry of the finite time period, and in which the high power mode of the device is configured so as to be operable do at least one of:
- read sensor data at an increased rate in order to gather sensor data; and
send a communication signal at an increased rate for establishing a connection for transmitting data.

Abstract
A monitoring device for monitoring treatment of the item that includes a sensor for sensing a condition relating to the treatment of the item, a memory arranged to store sensor data, and a communication interface for generating a wireless signal for transmitting the data. The device also includes a detector for detecting a predetermined event relating to the condition. The device is triggered to switch from a low power mode to a high power mode for a finite time period following detection of the predetermined event, and to switch from the high power mode to the low power mode upon expiry of the time period. In the high power mode the device is configured so as to read sensor data at an increased rate in order to gather sensor data or to send a communication signal at an increased rate for establishing a connection for transmitting data.

25. A method of monitoring, using apparatus powered by a cell, the treatment of an item during handling or storage, the method comprising:
- sensing a condition relating to the treatment of the item;
storing data arising from said sensing;
detecting a predetermined event relating to the condition;
switching from a low power mode to a high power mode for a finite time period following detection of the predetermined event, the power consumption of the apparatus being relatively higher in the high power mode compared to the low power mode;
in the high power mode doing at least one of reading sensor data at an increased rate compared to the low power mode in order to gather sensor data, and sending a communication signal at an increased rate compared to the low power mode for establishing a connection for transmitting data; and
switching from the high power mode to the low power mode upon expiry of the time period.
- sensing a condition relating to the treatment of the item;
