Abstract: Surgical systems and methods facilitate simulation of a prior use of a surgical instrument. Such surgical systems include a surgical instrument having a memory storing prior usage data of the surgical instrument in a usage data file(s), a processor configured to generate a simulation of the prior use based upon the usage data file(s), and a display configured to visually display the simulation of the prior use. Such methods include obtaining usage data from the prior use, storing the usage data in a usage data file(s), transmitting the usage data file(s), generating a simulation of the prior use based upon the usage data file(s), and displaying the simulation of the prior use.

Abstract: A motor vehicle solenoid including a solenoid housing, at least one coil arranged in the housing, and at least one diode holder arranged in the housing adjacent the at least one coil. The at least one diode holder includes a body having an outer circumferential edge and at least one diode pocket. The at least one diode pocket houses a diode electrically connected to the at least one coil.

Abstract: An integrated circuit device comprises a processor and a secure protection zone with security properties that can be verified by a remote device communicating with the integrated circuit device. The secure protection zone includes a persistent storage that is configured for storing cryptographic keys and data. The secure protection zone also includes instructions that are configured for causing the processor to perform cryptographic operations using the cryptographic keys. In addition, the secure protection zone includes an ephemeral memory that is configured for storing information associated with the cryptographic operations. The instructions are configured for causing the processor to perform the cryptographic operations on the data stored in the persistent storage and the information in the ephemeral memory as part of a secure communication exchange with the remote device.

Abstract: A method and device include a power pin, a ground pin, and a communications pin. A communications module receives power from the power pin and utilizes an edge counting communication protocol over the communication pin.

Abstract: Systems and techniques for performing cryptographic operations based on public key validity registers are described. A described system includes a controller and a memory structure to store one or more public keys. The memory structure includes one or more validity registers that respectively correspond to the one or more public keys. The controller has exclusive write access to the validity register. The controller can be configured to perform an authentication of a public key, write an authentication status value to the corresponding validity register based on a result of the authentication, and perform one or more cryptographic operations using the public key that are conditional on the validity register indicating an authenticated status for the public key.

Abstract: Methods and systems are disclosed for verifying the use of a client device by a host device in a secure system. In one aspect, a method for authenticating a client device includes receiving, by the client device, a message from a host device, accessing, by the client device, a private key and a unique code stored on the client device, where the unique code is different than the private key, generating, by the client device, a digital signature for the message using the private key and the unique code, and providing, by the client device, the digital signature to the host device for verification of the use of the client device by the host device.
