Abstract: Secure conditional transfer of cryptographic data allows transfer of cryptographically-based data from one party to another while mitigating failure of a counterparty to perform. A first party uses a first device to send a proposal to a second party's device. If the proposal is accepted, it is signed by the second device. A secure channel is established between the devices that also attests to their compliance during processing. Transaction identifiers associated with the proposal and other information are exchanged. Once exchanged, the first device creates and sends first transfer data (that may be signed) to the second device. The second device receives and determines the first transfer data is valid. In response, the second device creates and sends second transfer data (that may be signed) to the first device. If a communication or other failure prevents reciprocation by the second party, others may verify the transaction and confirm the failure.

Abstract: A general computing environment (GCE) determines request data comprising payload data and instruction data to use cryptographic functions in a secure computing environment (SCE). The SCE provides secure input and output devices, allowing secure presentation to a user and acquisition of user input. The SCE receives the request data and processes the payload data using the instructions in the instruction data to produce cryptographic output data. The request data may be determined using schemas that specify the formatting, grammar, and other attributes of data associated with a transaction that utilizes cryptographic functions. By using schemas and the request data, the SCE may support any protocol that uses the cryptographic functions supported by that SCE to compose cryptographic output. To enhance user comprehensibility and security, the SCE may securely replace some data with human readable text or images and present this as abstracted request data.

Abstract: A secure device comprises a secure computing environment (SCE) that stores one or more cryptographic secrets, such as private keys, and is able to receive input from secure input devices such as a keypad or smartcard interface and provide output to secure output devices such as a secure display. The SCE provides safeguards against remote and physical exploits, erasing or rendering unusable the secrets in the event of actual or suspected exploit, protecting the secrets from compromise. The SCE may digitally sign internally generated messages or messages from an external device such as a smartphone. Message signing conditions may be checked and satisfied in the SCE before a digitally signed message is generated. Messages may be automatically signed if they satisfy specified conditions. The secure device may be used as part of a multisignature scheme in which a plurality of private keys are used to create a digital signature.

Abstract: A system enables cryptocurrency payment transactions between devices using off-chain asset data that is related to blockchain assets within a blockchain but without committing the payment transaction to the blockchain until a later time. A device selects a settlement model to determine if a payment transaction is valid. When valid, the device adjusts a value of off-chain asset data stored in its memory. The device may aggregate multiple transactions, which may involve the same or different cryptocurrencies, adjusting the value of the off-chain asset data stored in its memory after each transaction. Subsequently, the device may commit at least a portion of the off-chain asset data to the blockchain.

Abstract: A method and system for raising the operating temperature of an emissions control device of an automotive vehicle. A generator converts the vehicle's mechanical braking energy to electrical energy. The electrical energy is delivered, without electrical storage, to an electric heater that heats either the emissions control device or the exhaust gas at the input to the device.

Abstract: The invention relates to an apparatus and method of statically sealing a reciprocating-type fuel pump, such as a direct injection high pressure piston-type fuel pump. The first embodiment of the invention is a fuel pump comprising a pump body, a fuel reservoir within the pump body, wherein the fuel reservoir is capable of holding fuel and a bellows attached to the pump body, wherein the bellows is a stretchable membrane acting as a static seal. The second embodiment further comprises a diaphragm seal inside the pump body, and adjacent to the fuel reservoir, and a working fluid reservoir adjacent to the diaphragm seal, wherein the working fluid reservoir is capable of holding fluid. The diaphragm seal is a static seal separating the working fluid reservoir and the fuel reservoir.
