1. An active RF identification label comprising:
- a memory for storing data;
means for generating a RF identification signal which requires a power source;
an activatable battery connected to said RF generating means for providing the required power;
said battery comprising at least a first component and a separate second component, said first and second components being physically isolated such that said battery is activated when said first component comes in operative physical contact with said second component;
means for permanently maintaining said first and second battery components in operative contact with each other after activation of the battery whereby an RF identification signal is producible on demand by activation of said battery; and
a control unit, coupled to said battery, said RF signal generating means and said memory, for controlling the generation of said RF identification signal to selectively output data from said memory into said RF identification signal for transmission,said control unit being programmable to output data from said memory having a hither priority more frequently than data having a lower priority for transmission.

Abstract
An RF identification label includes a selectively activatable battery and control and RF generating circuitry which is coupled to the battery. The battery includes two separate components which are brought together in operative contact to activate the battery and provide power to the control and RF generating circuitry. The preferred embodiment of the control and RF generating circuitry includes a programmable integrated circuit with contacts which permit programming by a user to define the identification signal which is generated.

5. An RF identification label for tracking an object comprising:
-
a memory for storing data; means for generating a RF identification signal; a selectively activated battery to power said RF generating means, said battery having electrically isolated components which are electrically connected upon said selection; a control unit, coupled to said battery, said RF signal generating means and said memory, for controlling the generation of said RF identification signal to selectively output data from said memory into said RF identification signal for transmission; and means for affixing the label to an object to be tracked, said control unit being programmable to output data from said memory having a higher priority more frequently than data having a lower priority for transmission. - View Dependent Claims (6, 7)
