| 20080258806 | Phase-Locked Loop Based Controller for Adjusting an Adaptive Continuous-Time Filter - A direct conversion radio-frequency (RF) receiver includes a controller and an adaptive continuous-time filter. The adaptive continuous-time filter receives a multiple-bit control signal generated by the controller to adjust a characteristic of the continuous-time filter. The controller generates the multiple-bit control signal in response to process variation in the semiconductor material used to implement the controller and the adaptive continuous-time filter. A method for tuning an adaptive continuous-time filter comprises determining a RC time constant, converting the RC time constant to a digital word, comparing a select bit of the digital word to a respective bit of a predetermined reference word to generate a control bit, applying the control bit to an adjustable element to modify the RC time constant, repeating the determining, converting, comparing and applying steps until the control bits generate an output word and providing the output word to the adaptive continuous-time filter. | 10-23-2008 |
| 20090281422 | Multi-modality system for imaging in dense compressive media and method of use thereof - A multi-modality system and method for performing detection, characterization and imaging of materials and objects in dense compressive media, such as in medical soft tissue applications, is disclosed. Medical tissue applications include but are not limited to the detection and diagnosis of breast tumors. Generally, an ultrasound subsystem is employed to excite a region in the dense compressive media and a microwave subsystem is employed to collect detection, characterization and imaging information from the excited region. In one preferred embodiment, multiple focused oscillating high-frequency ultrasound wave beams are transmitted into the media. The resultant low beat-frequency wave creates a force inducing motion in the materials and objects in the media. A radio-frequency microwave subsystem detects that motion and produces images based upon the Doppler effects of the excited materials and objects. | 11-12-2009 |

| 20090072850 | FORKED PROBE FOR TESTING SEMICONDUCTOR DEVICES - A novel forked probe design for use in a novel probe card is presented that comprises a forked bending element that more efficiently stores displacement energy. Specifically, the novel probe card comprising a substrate and a forked probe connected to the substrate. The forked probe includes a base that is connected to the substrate and a forked bending element connected to the base, wherein the forked bending element comprises at least a first prong connected to a second prong through a prong connecting structure and a handle connected to the prong connecting structure. Connected to the first prong is the probe tip that is adapted to make contact with the DUT. Refinements to the probe card include that the first and second prongs are adapted to bend such that each prong elastically stores a portion of the displacement energy when the probe tip contacts the DUT. Also, the forked bending element may be manufactured using photolithography and using layered photolithography. Each prong may be comprised of different materials. And the forked bending element may be comprised of a nickel alloy. Also, the first prong may be constructed to be stiffer than the second prong, which may yield a shorter scrub length. The stiffness of the prongs may be manipulated by altering the geometry and/or material of the prongs. | 03-19-2009 |
