  • Patent number: 8552734
    Abstract: The integrated circuit (10) has an internal power supply domain with a power supply voltage adaptation circuit (14) to adapt the power supply voltage in the power supply domain. Typically, a plurality of such domains is provided wherein the power supply voltage can be adapted independently. During testing an internal power supply voltage is supplied to a temporally integrating analog to digital conversion circuit (16) in the integrating circuit (10). A temporally integrated value of the power supply voltage is measured during a measurement period. Preferably, integrating measurements of a plurality of internal supply voltages are performed in parallel during the same measurement time interval. Preferably a further test is performed by changing over between mutually different supply voltages during a further measurement period. In this way the measured integrated supply voltage can be used to check the speed of the change over between the different voltages.

  • Patent number: 8549171
    Abstract: A method is disclosed for high-speed processing of structured application messages in a network device. According to one aspect, a network device receives a set of message classification rules that have been prepared beforehand by a system administrator or customer. The system analyzes the message classification rules to determine what part(s) of the message are necessary to classify a message according to the message classification rules. This allows the system to consider only the relevant parts of the message and ignore the rest of the message. The system extracts the portion of the message necessary for classifying the message and classifies the message using the values of the extracted information and the message classification rules. A unique sequence of operations is implied by the message classification and those operations must then be applied to the message.

  • Patent number: 8515695
    Abstract: A method and an apparatus for evaluating SDDC of a test pattern set are disclosed. In one embodiment, the method includes: (1) selecting a transition fault of an IC detected by a test pattern set, the transition fault occurring at a fault site of the IC, (2) identifying path delays of a longest testable path and a longest tested path of the IC, wherein both the longest testable path and the longest tested path include the fault site, (3) determining a SDD detection probability for both the longest testable path and the longest tested path based on a probability that a SDD will be detected if present at the fault site and (4) calculating SDDC for the transition fault by dividing the SDD detection probability of the longest tested path by the SDD detection probability of the longest testable path.

  • Publication number: 20130142230
    Abstract: An apparatus can receive and transfer data and energy between adjacent apparatus in a chain. Each apparatus comprises an input antenna for receiving an input signal which is tuned and impedance matched for a receiver and demodulator in a control circuit. The demodulated signal is provided as input to a transmitter module to create an output signal. The input signal is then impedance transformed to generate a sufficient voltage to energize a power supply which charges a battery. The input signal and the output signal can be a radio signal, a magnetic induction signal, or a combined radio and magnetic induction signal. A controller in the control circuit monitors the condition of the battery and power supply and controls a switch operable to selectively power parts of the apparatus dependently upon their monitored condition.

  • Patent number: 8436639
    Abstract: A multiple level integrated circuit uses an array of oppositely oriented individually enabled buffers between through-silicon vias (TSVs) and a clocked flip-flop, for each of multiple signal lines that include TSVs. Applying and/or reading logic levels to and from the TSVs and associated flip-flops produces values that a logic element compares to expected values characterizing nominal operation or detects open and short circuit defects. A process associated with testing the TSVs during assembly comprises testing for short circuits and then exposing and connecting the TSVs via a conductive layer to check for open circuits.
