| 20100190458 | METHOD OF TUNING RECEIVER HAVING TUNABLE AMPLIFIER WITH INTEGRATED TRACKING FILTER - A method of tuning a receiver includes: providing a tunable Low Noise Amplifier (LNA) having a plurality of LNAs and a plurality of LC loads coupled to the plurality of LNAs; selecting a desired LNA and a LC load corresponding to the desired LNA; isolating the desired LNA from the selected LC load; generating a local oscillation (LO) signal; routing the LO signal to the output of the tunable LNA to generate a filtered LO signal; determining a first signal power level of the filtered LO signal; changing the capacitance in the selected LC load and determining a second signal power level of the filtered LO signal; comparing the first filtered signal power level to the second filtered signal power level; and according to the comparison result, determining whether or not to adjust the capacitance in the selected LC load. | 07-29-2010 |

| 20110032165 | ANTENNA WITH MULTIPLE COUPLED REGIONS - An antenna having a driven element coupled to multiple additional elements to resonate at multiple frequencies. A magnetic dipole mode is generated by coupling a driven element to a second element, and additional resonances are generated by coupling additional elements to either or both of the driven or second element. One or multiple active components can be coupled to one or more of the coupled elements to provide dynamic tuning of the coupled or driven elements. | 02-10-2011 |

| 20090053801 | Shallow multi-well plastic chip for thermal multiplexing - Disposable units in current use for performing PCR are limited by their heat block ramping rates and by the thermal diffusion delay time through the plastic wall as well as by the sample itself. This limitation has been overcome by forming a disposable plastic chip using a simple deformation process wherein one or more plastic sheets are caused, through hydrostatic pressure, to conform to the surface of a suitable mold. After a given disposable chip has been filled with liquid samples, it is brought into close contact with an array of heating blocks that seals each sample within its own chamber, allowing each sample to then be heat treated as desired. | 02-26-2009 |

| 20110293959 | METHOD FOR TWISTING HOLLOW BARS - A method for fabricating a hollow bar that forms elements of a grille or railing of a metalwork piece where the bar is twisted manually, machine-assisted or automated machinery, into a spiral form for decorative or ornamental purposes. By providing the hollow bar to be comprised of separate longitudinal parts which may be hinged-joined to complementarily fastened to each other to form the hollow bar, the longitudinal joints are thus amenable to increased torsional stress, such that each of the parts may be twisted without breaching the material's fatigue limit and the bar as a whole capable of being twisted with more spiral turns within its elasticity limits. The twisted bar may thus be released for re-working for adjustments or re-installation. A number of exemplary joint embodiments, internal and external bracing accessories are also disclosed to cater for the different longitudinal part fabrication, e.g. by extrusion or roll-milling. | 12-01-2011 |

| 20100232915 | Apparatus For Handling A Semiconductor Component - An apparatus for handling or transferring a semiconductor component. The apparatus comprises a first structure and a second structure coupled thereto. The first structure and the second structure define a vacuum chamber therebetween. The second structure comprises at least one module coupled thereto. Each module comprises a passageway defined therethrough. Vacuum is applied through the passageway for facilitating pick up of the semiconductor component at a first position and for securing the semiconductor component to the module during displacement of the module from the first position to a second position. The apparatus comprises a plunger. Displacement of the plunger from a retracted position to an extended position impedes fluid communication between the passageway of the module and the chamber. Displacement of the plunger to the extended position further causes purging of air through the passageway of the module to thereby detach the semiconductor component from the module. A method for transferring the semiconductor component using the apparatus is also provided by the present invention. | 09-16-2010 |

| 20100258939 | STACKED MICROFEATURE DEVICES AND ASSOCIATED METHODS - Stacked microfeature devices and associated methods of manufacture are disclosed. A package in accordance with one embodiment includes first and second microfeature devices having corresponding first and second bond pad surfaces that face toward each other. First bond pads can be positioned at least proximate to the first bond pad surface and second bond pads can be positioned at least proximate to the second bond pad surface. A package connection site can provide electrical communication between the first microfeature device and components external to the package. A wirebond can be coupled between at least one of the first bond pads and the package connection site, and an electrically conductive link can be coupled between the first microfeature device and at least one of the second bond pads of the second microfeature device. Accordingly, the first microfeature device can form a portion of an electrical link to the second microfeature device. | 10-14-2010 |

| 20100128453 | TUNER - A tuner is disclosed which overcomes a problem related to leakage currents within a tuner associated with increased miniaturization. The tuner includes an oscillator and a cover. The cover includes a barrier region, typically in the form of a slot or an air gap, which impedes the propagation of leakage currents, in the form of eddy currents induced from the oscillator, along the cover from the oscillator region to other components in the tuner, and in particular to the input or output connectors. | 05-27-2010 |
