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.

8. A Radio Frequency Identification (RFID) tag comprising:
-
a vibration or movement sensor configured to produce an electrical signal in response to vibration or movement; a junction configured to split the electrical signal into a first electrical signal portion and a second electrical signal portion; a microprocessor including a memory, the microprocessor configured to (i) receive the second electrical signal portion of the electrical signal and (ii) store data, based on the received second electrical signal portion of the electrical signal, in the memory of the microprocessor indicative of the vibration or movement; and an energy storage device configured to (i) store energy on receipt of the first electrical signal portion of the electrical signal and (ii) supply the stored energy to the microprocessor to enable the microprocessor to process or store the data indicative of the vibration or movement based on the second electrical signal portion of the electrical signal. - View Dependent Claims (9, 10, 11)
