| 20100033359 | NONLINEAR COMPENSATION IN ANALOG TO DIGITAL CONVERTERS - An apparatus for converting an analog signal to a digital signal comprising a first analog to digital converter for generating a first digital value from an analog value. A second analog to digital converter for generating a second digital value from the analog value. Logic for determining a correction factor for the second digital value based on a difference between the first digital value and the second digital value, wherein the logic updates the correction factor. | 02-11-2010 |
| 20100060496 | MINIMIZING ADVERSE EFFECTS OF SKEW BETWEEN TWO ANALOG-TO-DIGITAL CONVERTERS - Skew between a first clock signal received by a first analog-to-digital converter (ADC) and a second clock signal received by a second ADC is adjusted to minimize error. Each ADC has an ADC element that produces a respective first or second digital output signal in response to an analog input signal and a respective first or second clock signal. A correction signal is produced in response to the first and second digital output signals. The skew between the first and second clock signals is then adjusted in response to the correction signal. | 03-11-2010 |
| 20100303144 | ARCHITECTURE FOR VERY HIGH-SPEED DECISION FEEDBACK SEQUENCE ESTIMATION - A method for providing a next-cycle input sample from a decision feedback equalizer to a symbol decoder using look-ahead computations such that timing contention between the decision feedback equalizer and the symbol decoder is reduced. During a symbol period, a set of possible values is computed in the decision feedback equalizer and a set of path memory symbols is computed in the symbol decoder, the set of path memory symbols being based on a current input sample. During the same symbol period, one of the possible values is selected as the next-cycle input sample based on at least one of the next-cycle path memory symbols produced from the symbol decoder. | 12-02-2010 |

| 20090086805 | APPARATUS FOR, AND METHOD OF, PROCESSING SIGNALS TRANSMITTED OVER A LOCAL AREA NETWORK - Systems for recovering communicated information in a communication system are disclosed and may include at least one digitizer for digitizing an analog received signal comprising the communicated information, thereby creating a digital received signal. The system may include at least one filter for bandwidth-limiting at least a portion of the digital received signal. At least one feed forward equalizer may be used for equalizing at least a portion of the bandwidth-limited signal to create an equalized signal. At least one converter for creating a data signal according to at least the equalized signal. At least one soft decision circuit for creating a soft decision signal according to the data signal. The soft decision circuit may cancel at least a portion of the equalized signal. | 04-02-2009 |

| 20110170088 | Sensors, Systems and Methods for Position Sensing - Various systems and methods for estimating the position of a radiation source in three-dimensional space, together with sensors for use in such systems are described. In some embodiments, the systems include a plurality of radiation sensors. The three-dimensional position of the radiation source is estimated relative to each sensor using an aperture that casts shadows on a radiation detector as a function of the incident angle of the incoming radiation. In some embodiments, the ratio of a reference radiation intensity to a measured radiation intensity is used to estimate direction of the radiation source relative to the sensor. When the angular position of the radiation source is estimated relative to two sensors, the position of the radiation source in three dimensions can be triangulated based on the known relative positions of the two sensors. | 07-14-2011 |
