Abstract:
A radio frequency controller device is provided that enables the utility of an integrated circuit (IC) device 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 IC's utility should be changed, and sets the state of the switch accordingly. The radio frequency controller device also has an IC interface that allows the IC to determine the state of the switch, and based on the state of the switch, a different utility will be available for the integrated circuit device. The radio frequency controller device also has an antenna for the RF communication, as well as a demodulator/modulator circuit.
Abstract:
A conditional access network is provide that generates and captures authenticated events. These authenticated events are securely generated responsive to communications between the network and processors, where the processors are embedded in associated targets or products. Events may be, for example, receiving targets into inventory, shipping targets to another entity, activating targets at a point of sale, or permanently disabling a defective target. These authenticated events are captured by the network, and used to support transactions. For example, the timely and trustworthy information derived from the authenticated events can be used to support financial, ownership, or regulatory transactions. In one use, the authenticated events enable a consignment business model where the distributor, retailer, and products all participate in the conditional access network. With the timely and accurate inventory, sales, and return information provided by the authenticated events, disputes over settlement are dramatically reduced.
Abstract:
Automated financing products, services, and processes are enabled by the more complete, timely, and accurate information provided by a conditional access network. In one example, the financing product is an automated loan process. The automated loan process is able to receive timely product information, such as product status and location, and adapt loan terms, rate, or loan amount responsive to the information. For example, a loan may be adapted according to product activations, products that are deactivated, or according to which distributor is holding product. Information from the conditional access network may also be used to evaluate repayment terms. For example, the loan provider can use information from the conditional access network to confirm status of collateral, and accelerate the loan as appropriate. In this way, loan risk is reduced.
Abstract:
Automated insurance products, services, and processes are enabled by the more complete, timely, and accurate information provided by a conditional access network. Automated insurance processes are able to receive timely product information, such as product status and location, and adapt insurance policies or coverage responsive to the information. For example, an insurance policy may be adapted according to product activations, products that are deactivated, or according to which distributor is holding product. Information from the conditional access network may also be used to evaluate policy claims. For example, the insurance provider can use information from the conditional access network to confirm specific item coverage, to determine if products moved through authorized distributors, and to make sure they do not pay claims for items actually sold and activated. In this way, the insurance provider in enable to make more accurate and timely claim payments.
Abstract:
A switch device is provided that selectively enables the utility of a processing device. In one example, the processing device is a microprocessor operating in a target device, such as a computer system, and the switch device is a radio frequency controller device that sets the switch responsive to an RF signal. The processing device only operates when: 1) the processing device is installed in the expected target device; and 2) the switch has been activated, for example, using the RF signal. The radio frequency controller device has a switch that is set to a defined state responsive to the RF signal. Conditional logic circuitry may use the RF signal to determine if the switch should be activated, and sets the state of the switch accordingly. The radio frequency controller device operates a data processing process only when the switch is activated. A processing device sends data to the radio frequency controller device, and if the switch is active, the processing device receives modified data in response. The processing device also generates expected data, and compares the expected data to the modified data. If the expected data matches the modified data, then the processing device is allowed to operate.
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 radio frequency identification device provides a stored identification value to a radio frequency reader. The radio frequency identification device stores the identification value in a logic/memory block, and has an antenna and demodulator circuit connected to the logic/memory block. The antenna is spaced remotely from the logic/memory block, with a connector electrically coupling the antenna to the logic/memory block. In one implementation, the antenna is on an antenna member and is external to a target device, while the logic/memory block is placed inside the target. In this way, the antenna is positioned for improved RF communication. The antenna member may electrically and mechanically connect to the target through a connector, such as a custom connector, power connector, audio connector, or video connector.
Abstract:
A radio frequency activation device enables the activation of a target using RF communication. The radio frequency activation device has a switch that is initially set to a state that disables or substantially interferes with the use of a target function. Responsive to the receiving the RF communication, the switch is set to another state where the function is available. The controlled activation may apply to the target as a whole, or may apply to a selected function, module, peripheral, or component of the target. The radio frequency activation 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, either allows or disallows the affected function. The radio frequency activation device also has an antenna for the RF communication, as well as a demodulator/modulator circuit. When used to activate an electrical or electronic device, the radio frequency activation 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 target having a controlled utility is provided, as well as a method for changing the utility of the target. The target with controlled utility may be an electronic device, or alternatively, may be a tangible media, such as an optical disc. The controlled target has a change effecting device that is set to a first state, which allows the target to operate according to a first utility. The controlled target also has a receiver for receiving an authorization key, and logic which, responsive to the authorization key, selectively changes the change effecting device to a second state. When the change effecting device is in the second state, the target may operate according to a second utility. In one example, the controlled target has a restricted access key that was stored during manufacture, and the restricted access key is used by the logic in changing the state of the change effecting device. To change the utility of the controlled target, the controlled target is placed proximate to an activation device. The activation device may read an accessible identifier from the controlled target, and retrieve or generate an authorization key that is associated with the target. The activation device may cooperate with a network operation center or other entity to retrieve the authorization key, and to obtain approval to change the utility of the controlled target. If approved, the activation device may then send the authorization code to the controlled target.
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 or deactivated state to an activated state, or that a target device has been 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 an authorized sale or other event, a switch in the DVD may be transitioned to an 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.
