  • Controller area network bus based security communications method, apparatus, and system
    Patent number: 11271771
    Abstract: A controller area network bus based security communications system includes a gateway electronic control unit (ECU) and at least one control area network (CAN) bus ECU. The gateway ECU generates a random number, and sends the random number to the at least one CAN bus ECU. A first CAN bus ECU obtains the random number sent by the gateway ECU, and generates a first information authentication code based on a key of a first CAN identifier, the random number sent by the gateway ECU, a count value of the first CAN identifier, and data of a first CAN packet.
    Type: Grant

  • Spring-based probe pin that allows kelvin testing
    Patent number: 7271606
    Abstract: The voltage at a node of an integrated circuit can be measured or controlled using a two-wire kelvin contact with spring-based probe pins by offsetting and tapering the lower end section of the spring-based probe pin. As a result, multiple spring-based probe pins can be connected to a single contact bump, such as a solder bump.

  • Pricing system and method for multiple discounts
    Publication number: 20050256772
    Abstract: The invention provides a data processing system and method for pricing a plurality of goods to be purchased by a customer, based on a plurality of predetermined discount criteria. According to the invention, an amount of discount relative to N goods is generated according to some applicable discount criteria selected from the predetermined discount criteria and an order information including data associated with the goods. The pricing regarding the goods is calculated by subtracting the sum of all prices of the goods by the total amount of discount.
