  • Patent number: 12281373
    Abstract: A wire of a nickel-titanium alloy having a permanent set of less than 5% when 11% strain is applied to the wire is disclosed. The wire may be formed by applying a first heat treatment to the wire, the first heat treatment includes applying heat of a first temperature for a first period of time, applying a strain deformation to the wire to set a shape for the wire during the first heat treatment, and applying a second heat treatment to the wire. The second heat treatment includes applying heat of a second temperature different from the first temperature for a second period of time, and the second temperature is between 210° C. and 290° C. The wire may have a modulus of at least 53 GPa when 200 MPa of stress is applied to the wire, and the wire is bonded to a secondary component.

  • Publication number: 20250016131
    Abstract: Systems and methods are disclosed for determining whether a message received by a client may be spam, in a computing environment that preserves privacy. The message may be encrypted. A client invokes the methods when a message is received from a sender that is not known to the client. A client can decrypt the message, break the message into chunks, and apply a differentially private algorithm to the set of chunks. The client transmits the differentially private message sketches to an aggregation server. The aggregation server receives a large collection of such message sketches for a large plurality of clients. The aggregation server returns aggregated message chunk (e.g. frequency) information to the client to assist the client in determining whether the message may be spam. The client can process the message based on the determination without disclosing the message content to the server.

  • Publication number: 20240345841
    Abstract: In one embodiment, a processor comprises: a first configuration register to store a pointer to a process address space identifier (PASID) table; and an execution circuit coupled to the first configuration register. The execution circuit, in response to a first instruction, is to obtain command data from a first location identified in a source operand of the first instruction, obtain a PASID table handle from the command data, access a first entry of the PASID table using the pointer from the first configuration register and the PASID table handle to obtain a PASID value, insert the PASID value into the command data, and send the command data to a device coupled to the processor. Other embodiments are described and claimed.

  • Publication number: 20240325984
    Abstract: Cation exchange membranes are prepared via facile methods to control sulfonation of polystyrene repeat units. An amount of sulfuric acid is reacted with an acetic anhydride to form an amount of acetyl sulfate. The acetyl sulfate is then added to a known concentration of polystyrene units in boiling dichloromethane (DCM) to form sulfonated polystyrene random copolymers, including a random distribution of sulfonated polystyrene repeats and unsulfonated polystyrene repeats, with sulfonation levels between about 0.07 and about 0.225. The sulfonation level can be controlled by adjusting reaction times, reaction temperatures, and sulfuric acid loading in the reaction mediums. These membranes, neutralized via alkali metals, exhibit high charge densities and low hydration degrees, and maintain high permselectivity under various high solution concentrations.

  • Publication number: 20240259177
    Abstract: Methods and systems for extending white-box cryptography are provided. A computing device can maintain, in a memory, one or more cryptography keys encrypted using a white-box cryptography solution. The one or more cryptography keys encrypt or decrypt data with a cryptography algorithm not supported by the white-box cryptography solution. The computing device can perform one or more anti-tampering verifications to detect tampering events for tampering with the computing device or an application installed on the computing device. The computing device can, upon determining that no tampering event is detected, decrypt the one or more cryptography keys using the white-box cryptography solution, and provide the one or more cryptography keys to encrypt or decrypt the data using the cryptography algorithm not supported by the white-box cryptography solution.
