| 20100150284 | GPS RECEIVER WITH IMPROVED IMMUNITY TO BURST TRANSMISSIONS - GPS signals are typically weak and thus easily interfered with by other radio transmissions in the same or adjacent frequency bands. Interference can be especially problematic when the GPS receiver is co-located with a communications device that includes a radio transmitter, such as a cellular telephone. The transmitted signal from the co-located communication device can overload (or saturate) the GPS receiver front-end designed to receive weak GPS signals. In such a situation no useful information can be extracted from the received GPS signals originating from the GPS satellites. Described herein is a novel apparatus and method that can be used to minimize the effect of co-located interference on a GPS receiver. | 06-17-2010 |
| 20100248674 | Switchable Mode Filter for Overlaid Signal Extraction in Noise - A method of extracting predetermined narrowband microwave signals having common transmission center frequency is presented through the teachings of the invention. In an embodiment of the invention a software based signal processing approach is employed to identify the microwave signals present and control an adaptive bandwidth filter to provide an approximately optimal transmission bandwidth of the adaptive bandwidth filter for the selected microwave signal and minimized noise into the correlation process. | 09-30-2010 |

| 20100149430 | Active Inductor Circuits for Filtering in a Cable Tuner Circuit - An integrated front-end filter for a tuner provides an array of from several to a multitude of passbands, each for passing at least one but less than all channels designated in a band of frequencies. Each passband is exclusively selectable. The integrated front end filter includes at least one active filter unit with an active reactance element in either of fixed and variable filter configurations and a decoder coupled to said at least one active filter unit and being responsive to a control signal for selecting a one of the passbands. In one example a multitude of active filter units of fixed filter configuration provide the multitude of passbands. Each data is stored at a predetermined location and reproduced in response to a corresponding control data signal from a tuner controller. Each data characterizes one of the plurality of passbands. The filter element is switchable from one passband to another in response to the control data signal. Lower power dissipation and lesser requirements of an on-following integrated circuitry tuner permit a reduction of “off chip” connections and cost. | 06-17-2010 |
