  • Patent number: 8635044
    Abstract: Embodiments of systems and methods for improved measurement of transient thermal responses in electronic systems are described herein. Embodiments of the disclosure use the known thermal transfer function of an electronic system to generate an equivalent resistor-capacitor (RC) network having a dynamic response that is identical to a given power excitation as the actual electronic system would have to that power excitation. Using the analogy between thermal and electrical systems, a Foster RC network is constructed, comprising a plurality of RC stages in which resistors and capacitors are connected in parallel. Subsequently, the analog thermal RC network is converted into an infinite impulse response (IIR) digital filter, whose coefficients can be obtained the Z-transform of the analog thermal RC network. This IIR digital filter establishes the recursive relationship between temperature output at the current time step and measured power input at the previous time step.

  • Patent number: 8618834
    Abstract: A method and apparatus configures an integrated circuit by determining a multi-bit configuration value on a single node. The multi-bit configuration value is determined by using at least a voltage level at the single node and also by detecting a time to reach a voltage threshold level at the single node, based on a voltage ramp generation circuit. The method and apparatus also includes configuring an operation mode of a circuit in the integrated circuit based on the determined multi-bit configuration value from the single node. Multi-bit configuration values may be obtained on multiple single nodes in an integrated circuit. In one example, a voltage level is employed in addition to a time to reach a voltage threshold level whereas in another example a current level on a single node is utilized in combination with detection of a time to reach a voltage threshold level.

  • Publication number: 20130344822
    Abstract: An apparatus and method is provided for improving initialization and synchronization of display devices to audio data. Current implementations to retain synchronization between a transmitter and a display use “Keep Alive” silent audio data stream in the format of the latest data stream on an interface between the transmitter and the display even when no data is available. Implementing the above solution in a system where the silent audio data stream is transmitted over a wireless link is bandwidth and power inefficient. The techniques provide an apparatus and method to efficiently generate and transmit silent audio data stream for maintaining synchronization.

  • Patent number: 8613818
    Abstract: Methods of refining the grain size of titanium and titanium alloys include thermally managed high strain rate multi-axis forging. A high strain rate adiabatically heats an internal region of the workpiece during forging, and a thermal management system is used to heat an external surface region to the workpiece forging temperature, while the internal region is allowed to cool to the workpiece forging temperature. A further method includes multiple upset and draw forging titanium or a titanium alloy using a strain rate less than is used in conventional open die forging of titanium and titanium alloys. Incremental workpiece rotation and draw forging causes severe plastic deformation and grain refinement in the titanium or titanium alloy forging.

  • Patent number: 8601667
    Abstract: In a robotic tool changer, a rotating cam surface ring having a plurality of surfaces formed therein urges a plurality of ball members in one tool coupling unit radially to contact a coupling surface in the other tool coupling unit. Mechanical energy captured and stored upon decoupling the units is used by an actuation mechanism, upon manual initiation, to at least partially automatically couple the two units by partially rotating the rotating cam surface ring. Further manual rotation of the cam member exerts a radial force through the ball members onto the coupling surface. A component of that force is directed by the coupling surface toward the opposite tool coupling unit, locking the two units together.
