MONITORING MOVEMENT
First Claim
1. A monitoring device for monitoring movement characteristics of an item with which the monitoring device is associated, the monitoring device comprising:
- a transducer operable to generate an electrical signal in response to movement of the item;
a radio-frequency identification device having a data recorder operable to record data on receipt of an electrical signal from said transducer, and a radio-frequency signal transmitter operable to transmit a radio-frequency signal indicative of data recorded by said data recorder;
an electrical store operable to store energy on receipt of an electrical signal from said transducer, said electrical store being operable to serve as a supply of energy for the radio-frequency identification device; and
an electrical signal splitter operable to split an electrical signal generated by the transducer into a first portion and a second portion, and to provide said first portion to said electrical store and said second portion to said radio-frequency identification device whereby to allow said data recorder to record data in dependence on said second portion.
