| 20090144364 | SMART NODES FOR WEB SERVICES - A smart node is integrated with each Web service in a Web service application chain to automatically supply compatible features, missing functionality. and orchestration of the processes in the application, without coordination by an orchestration engine, in an embodiment. A smart node is a software program that systematically specifies the communications dimensions, functionality, and orchestration required for interoperability among Web services. The communications parameters, backup functionality. and process orchestration required for the Web services in a Web service application may be predetermined and programmed into smart nodes. The smart nodes are subsequently integrated with the Web services in a Web service application so that communications among the Web services occur first through the smart nodes. The smart nodes can thus supply communications parameters, any missing functionality, and dynamic process orchestration based on the current event context of the Web service application. A smart node further enables a Web service to supply different functionality in different contexts. | 06-04-2009 |

| 20090097178 | METHODS AND APPARATUS TO DETECT AND OVER-CURRENT IN SWITCHING CIRCUITS - Methods and apparatus to detect an over-current in switching circuits are described. An example method to detect an over-current in a switching circuit includes randomly selecting a sensor from a plurality of sensors operatively coupled to an output stage of the switching circuit; detecting a first voltage via the randomly selected sensor; and comparing the first voltage to a reference voltage to generate a signal, wherein the signal indicates a status of the output stage of the switching circuit. | 04-16-2009 |

| 20120060133 | Annotation of RTL to Simplify Timing Analysis - A method for simulating operation of a design model for a digital system is provided. A library of functional cells is maintained in a storage unit that includes an attribute template with one or more of the functional cells in the library. The attribute template provides fields for specifying design constraint data for a functional cell each time it is instantiated in a design model. A design model is created and stored that includes one or more instantiations of a functional cell and its associated design constraint data. A set of test cases may be pruned to remove test cases that are not needed based on the design constraint data associated with the instantiated functional cells of the design model. | 03-08-2012 |

| 20090167429 | METHODOLOGY FOR ASSESSING DEGRADATION DUE TO RADIO FREQUENCY EXCITATION OF TRANSISTORS - One embodiment relates to an on-chip power amplifier (PA) test circuit. In one embodiment, a PA test circuit comprises a controllable oscillator (CO) configured to generate a radio frequency (RF) signal, a parallel resonant circuit tuned to the radio frequency, a pre-power amplifier (PPA) coupled to the CO and the parallel resonant circuit, the PPA configured to amplify and drive the RF signal from an output of the PPA into a load. The test circuit may further comprise a first transmission gate configured to couple the RF signal from the CO to an input of the PPA. One testing methodology for a PA test circuit comprises stressing the PPA with an RF signal, measuring a characteristic of the PPA, determining stress degradation from the characteristic measurements, and repeating the stressing and characteristic measurements until a maximum stress degradation is achieved or a maximum stress has been applied. | 07-02-2009 |
| 20090187869 | Budgeting Electromigration-Related Reliability Among Metal Paths In The Design Of A Circuit - Apportioning unequally contributions of different metal paths of a circuit to electromigration (EM) reliability. In an embodiment, a corresponding parameter value representing a magnitude of excess current flowing in a single direction in each metal path is determined. A desired reliability measure for electromigration (EM) is apportioned among the metal paths based on computed parameter values for the corresponding metal path. A reliability analysis for the circuit is performed based on the apportioning. In an embodiment, metal paths which predominantly carry currents with an average value less than a threshold are excluded from being considered as contributors to EM degradation. | 07-23-2009 |
| 20100038683 | INTEGRATED CIRCUIT MODELING, DESIGN, AND FABRICATION BASED ON DEGRADATION MECHANISMS - An integrated circuit (IC) includes at least a first complementary MOS (CMOS) circuit, the first CMOS circuit comprising one or more first n-channel MOS (NMOS) transistors and one or more first p-channel MOS (PMOS) transistors, where the first NMOS transistors and the first PMOS transistors are arranged in the first CMOS circuit to drive at least a first common node of the first CMOS circuit. An average of the effective gate channel lengths of the first NMOS transistors (first NMOS average length) is at least 2% greater than an average of the effective gate channel lengths of the first PMOS transistors (first PMOS average length). | 02-18-2010 |
| 20100164533 | METHOD AND APPARATUS FOR EVALUATING THE EFFECTS OF STRESS ON AN RF OSCILLATOR - Apparatus and methods are disclosed for evaluating degradation of a transistor in a cross coupled pair of an RF oscillator independently. A MOS device can be coupled between a separated center-tap inductor. By appropriately sizing the MOS device and turning the MOS device on during operation of RF oscillator, a good contact can again be made that allows the oscillator to operate at design performance. By turning the MOS device off, the supplies can be separates such that I-V characteristics of both transistors of the cross-coupled pair may be obtained. | 07-01-2010 |
| 20110291754 | Segmented Power Amplifier with Varying Segment Activation - Various apparatuses and methods for varying segment activation in a segmented power amplifier are disclosed herein. For example, some embodiments provide a power amplifier including an input, an output, a plurality of amplifier segments and a controller. The amplifier segments are connected in parallel between the input and the output and are adapted to be activated and inactivated. The power level at the output may be controlled by changing a number of the amplifier segments that are activated concurrently. The controller is connected to the amplifier segments and is adapted to vary which of the amplifier segments are activated to arrive at a selected number of activated amplifier segments. | 12-01-2011 |

| 20110052672 | TREATMENTS OF DISEASE OR DISORDERS USING NANOPARTICLES FOR FOCUSED HYPERTHERMIA TO INCREASE THERAPY EFFICACY - Methods are provided for the treatment of diseases and disorders using systematically-introduced nanoparticles to create a focused localized hyperthermia in a target area to enhance the effect of additional treatment therapies such as ionizing radiation. Advantages include an enhancement of the therapeutic effect of other therapies by increasing perfusion or reducing hypoxia in the treatment area, further, the methods herein may also result in the disruption of the vasculature, which provide further impetus for such treatments, singly and in combination with conventional therapies such as chemotherapy and radiation therapy. Methods for treating a target area may comprise systemically introducing nanoparticles into an organism; allowing the nanoparticles to preferentially accumulate in the target area, applying an external energy where the nanoparticles are adapted to transduce at least a portion of the external energy into a heal energy so as to create a focused localized hyperthermia; and applying a subsequent additional therapy. | 03-03-2011 |
