| 20110012775 | Locating System - The invention provides an antenna capable of performance similar to a Yagi-Uda antenna. However, unlike a conventional Yagi Uda antenna, the antenna of the invention is implementable on a substrate and thereby provides a directional antenna capable of disposition within a slender housing such as a cellular communications device. One embodiment of the invention provides an antenna comprising a substrate including a ground plane. The ground plane comprises a base portion and a spine portion extending from the base portion along a central axis of the substrate. A driven antenna element is disposed on a portion of the substrate and coupled to the spine portion to form a first antenna dipole. At least one antenna director element is disposed on a portion of the substrate and coupled to the spine portion to form a second antenna dipole. A reflector element comprises a portion of the ground plane. | 01-20-2011 |
| 20110149779 | RANGING FOR WIRELESS RADIO FREQUENCY COMMUNICATION DEVICES - The present invention relates generally to methods and systems for radio ranging and more particularly to methods and systems for determining time of arrival (TOA) of a ranging signal at a reference wireless device in order to determine distance between the reference wireless device and a target wireless device. | 06-23-2011 |

| 20100264296 | Mixed analog and digital pixel for high dynamic range readout - An improved CMOS pixel with a combination of analog and digital readouts to provide a large pixel dynamic range without compromising low-light performance using a comparator to test the value of an accumulated charge at a series of exponentially increasing exposure times. The test is used to stop the integration of photocurrent once the accumulated analog voltage has reached a predetermined threshold. A one-bit output value of the test is read out of the pixel (digitally) at each of the exponentially increasing exposure periods. At the end of the integration period, the analog value stored on the integration capacitor is read out using conventional CMOS active pixel readout circuits. | 10-21-2010 |

| 20090267120 | IMAGE DETECTION APPARATUS AND METHODS - MOS imaging pixels are described. The MOS imaging pixels may comprise bootstrapped source followers, having their bodies connected to their sources. The source followers of the MOS imaging pixels may be used to buffer a signal indicative of an amount of radiation incident on the pixel. MOS imagers are also described, which may comprise one or more MOS imaging pixels of the type described. | 10-29-2009 |
| 20100012841 | IMAGING APPARATUS AND METHODS - Imagers, pixels, and methods of using the same are disclosed for imaging in various spectra, such as visible, near infrared (IR), and short wavelength IR (SWIR). The imager may have an imaging array having pixels of different types. The different types of pixels may detect different ranges of wavelengths in the IR, or the SWIR, spectra. The pixels may include a filter which blocks some wavelengths of radiation in the IR spectrum while passing other wavelengths. The filter may be formed of a semiconductor material, and therefore may be easily integrated with a CMOS pixel using conventional CMOS processing techniques. | 01-21-2010 |
| 20100019154 | IMAGING APPARATUS AND METHODS - Optical imaging structures and methods are disclosed. One structure may be implemented as an imaging pixel having multiple photodetectors. The photodetectors may detect different wavelengths of incident radiation, and may be operated simultaneously or at separate times. An imager may include an imaging array of pixels of the type described. Methods of operating such structures are also described. | 01-28-2010 |
| 20110074995 | METHODS AND APPARATUS FOR IMAGING SYSTEMS - Imaging arrays comprising at least two different imaging pixel types are described. The different imaging pixel types may differ in their light sensitivities and/or light saturation levels. Methods of processing the output signals of the imaging arrays are also described, and may produce images having a greater dynamic range than would result from an imaging array comprising only one of the at least two different imaging pixel types. | 03-31-2011 |
