    Abstract: Data associated with supply chain events for a manufactured assembly is automatically stored. In preferred embodiments the supply chain events for the manufactured assembly are stored on an RFID tag attached to the assembly as it travels through the supply chain to insure the data concerning the assembly is readily available and not separated from the assembly. In other embodiments, the supply chain events or characteristic data is stored on the RFID tag in a hierarchical structure beginning with the original state of the assembly and with additional entries for each step in the assembly process. In other embodiments, as the product undergoes rework, conversion to a different assembly, or personalizations, the new state of the assembly is stored in the RFID tag. In other preferred embodiments, other information is also stored on the RFID tag such as country of origin, failure data, cycle times and a quality status indicator.

  • Publication number: 20080270822
    Abstract: There is provided a method and system for replicating data at another location. The system includes a source node that contains data in a data storage area. The source node is coupled to a network of potential replication nodes. The processor determines at least two eligible nodes in the network of nodes and determines the communication cost associated with a each of the eligible nodes. The processor also determines a probability of a concurrent failure of the source node and each of eligible nodes, and selects at least one of the eligible nodes for replication of the data located on the source node. The selection is based on the determined communication costs and probability of concurrent failure.

  • Publication number: 20080256499
    Abstract: A method for generating a constraint for generating a constraint for use in the verification of an integrated circuit design includes identifying a target in a netlist (N) of the design and creating an overapproximate abstraction (N?) of the netlist. A space state (S?) is created by enumerating the states of N? from which the identified target may be asserted. A constraint space C? is then derived from the state space S?, where C? is the logical complement of S?. The process is repeated for multiple selected targets and the constraint spaces from each iteration are logically ANDed. Creating an overapproximate abstraction may include replacing a sequential gate with a random gate. Identifying a sequential gate may include selecting a target in the netlist, performing underapproximate verification of the target, and, if a spurious failure occurs, selecting a gate further down the fanin chain of the currently selected gate.

  • Publication number: 20080251289
    Abstract: Methods and devices are provided for repairing a damaged contact pad that is located on a first surface of a printed circuit board and connected to a via that passes through the circuit board. According to the method, a countersink hole is created in the first surface of the printed circuit board in a location that is substantially centered on an axis passing through the via, and a replacement structure is inserted into the countersink hole. The replacement structure has a stem portion, a head portion, and a shoulder portion that connects the stem and head portions, with the angle of the shoulder portion substantially matching the angle of the shoulder of the countersink hole. The stem portion of the replacement structure is permanently attached to sidewalls of the via so as to electrically couple the head portion of the replacement structure to the via.

  • Publication number: 20080252331
    Abstract: A method for an electronic device is provided for preventing reverse engineering by monitoring light emissions emitted from transistors and such electrically active devices in the electronic device. The method emits extraneous randomized light emissions in substantial close proximity to the transistors to hide a pattern of light emissions emitted from the transistors. As one feature, the device can include a source of randomized light emissions in substantial close proximity to the transistors to hide a pattern of the emitted light from the transistors in randomized light emissions emitted by the source. As a second feature, the device can emit the randomized light emissions by randomly delaying an electrical signal that is electrically coupled to the transistors and, in response to the randomly delayed electrical signal, the transistors randomly emitting light emissions thereby hiding a separate pattern of light emission emitted from the transistors.

  • Publication number: 20080251840
    Abstract: An electronically scannable multiplexing device is capable of addressing multiple bits within a volatile or non-volatile memory cell. The multiplexing device generates an electronically scannable conducting channel with two oppositely formed depletion regions. The depletion width of each depletion region is controlled by a voltage applied to a respective control gate at each end of the multiplexing device. The present multi-bit addressing technique allows, for example, 10 to 100 bits of data to be accessed or addressed at a single node. The present invention can also be used to build a programmable nanoscale logic array or for randomly accessing a nanoscale sensor array.

  • Publication number: 20080243691
    Abstract: Account holders may specify vendor-specific charge restrictions for charging transactions against their accounts, where each vendor-specific charge restriction includes a unique identifier for the corresponding vendor to which the charge restriction is applicable. The charge restriction may be an exclusion from approval of all charge authorization requests, an amount limit on charge authorization requests which may be approved, a “rebill” limit on the number of times subsequent charge authorization requests may be approved, or a combination of such restrictions and/or other restrictions. When a charge authorization request is received for a charge against an account having vendor-specific charge restrictions set by the account holder, the vendor identifier is extracted from the charge authorization request and employed to determine whether any charge restrictions are applicable to the requesting vendor.

  • Publication number: 20080231311
    Abstract: A physically secure processing assembly is provided that includes dies mounted on a substrate so as to sandwich the electrical contacts of the dies between the dies and the substrate. The substrate is provided with substrate contacts and conductive pathways that are electrically coupled to the die contacts and extend through the substrate. Electrical conductors surround the conductive pathways. A monitoring circuit detects a break in continuity of one or more of the electrical conductors, and preferably renders the assembly inoperable. Preferably, an epoxy encapsulation is provided to prevent probing tools from being able to reach the die or substrate contacts.

    Abstract: A method for performing verification includes selecting a first set containing a seed register and adding to a second set a result of a subtraction of a fanout of the first set from a fanin of the first set. A third set is rendered equal to a result of a subtraction of a fanin of the second set from a fanout of the second set, and whether a combination of the first set and the third set is equivalent to the first set is determined. In response to determining that the combination of the first set and the second set is not equivalent to the first set, a min-cut of the first set and the second set containing a minimal set of predicates between a first component and the logic to which the component fans out, wherein the logic is bordered by the second set is returned.
