Abstract: A circuit and method is provided for confirming that an activation state for a target has been changed. For example, a confirmation signal or message may be generated that a target device has transitioned from a non-operating o deactivated state to an activated state, or that a target device has bee deactivated from an operating or activated state. The target may be, for example optical media or electronic or electrical devices. In one example, the target device is an optical media such as a DVD. The DVD may be deactivated at the time of manufacture and, distributed in a non-playable condition. Upon a authorized sale or other event, a switch in the DVD may be transitioned to a activated state, allowing the DVD to play normally. The switch, which may be an electro-optic or electrochromic material, is monitored for an amount of charge transferred to the switch. By monitoring the total charge or other charge characteristic, it may be confidently determined that the switch has properly changed to its activated state. A confirmation message may then be generated for local or remote use.

Abstract: A radio frequency controller device enables the utility of a target to be controlled using an RF communication. The radio frequency controller device has a switch that is set to a defined state responsive to the RF communication. More particularly, conditional logic circuitry uses the RF communication to determine if the target's utility should be changed, and sets the state of the switch accordingly. The radio frequency controller device also has a target interface that allows the target to determine the state of the switch, and based on the state of the switch, a different utility will be available for the target. The radio frequency controller device also has an antenna for the RF communication, as well as a demodulator/modulator circuit. When used to control the utility of an electrical or electronic device, the radio frequency controller device has a low-power circuit portion that is used to set the state of the switch responsive to the RF communication, and also has a full power circuit portion that communicates with the target. In this way, the state of the switch may be set when the target is in a power-off condition, and the target is able to determine the state of the switch when the target is activated.

Abstract: A distribution control system is provided to support the controlled and selective changing of utility for a target. The target with controlled utility may be an electronic device, or alternatively, may be a tangible media, such as an optical disc. The distribution control system has a target with a change effecting device and a restricted access key. An activation device retrieves or generates an authorization key, and sends the authorization key to the target. The authorization key may be sent to the target wirelessly, for example, using a radio frequency signal. The target has logic that uses the restricted access key and the authorization key to change the utility of the target. In one example, the activation device retrieves the authorization key from a network operation center (NOC) by sending a target identifier to the NOC, and the NOC retrieves the authorization key for the identified target. The activation device may also connect to other systems for obtaining approval to change the utility of the target. For example, the authorization key may be sent to the target upon receiving payment, password, or other confirmation.

Abstract: An integrated circuit device is provided for attachment to a target. In one example, the integrated circuit device is a tag attached to a product such as an electronic device or optical disc. In another example, the integrated circuit device may be integrated into the product's circuitry. The integrated circuit is controllable to effect an action at the target, such as activating or deactivating the usefulness of the product. The integrated circuit has a logic and memory section connected to an antenna for receiving communications from an associated reader or scanner. The integrated circuit also has a component constructed to transition from a first state to a permanent second state. For example, the component may be a fuse, a partial fuse, or an anti-fuse. The integrated circuit also stores a hidden secret kill code, and upon receiving a matching kill code from the reader, permanently transitions the component to its second state. When the component is in the permanent second state, the integrated circuit is incapable of effecting the action on the target. In this way, the integrated circuit's ability to affect the target may be permanently disabled. The integrated circuit may also verify its function is disabled, and report a kill confirmation to the reader.
