| 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 |
| 20120008701 | PHASE INTERPOLATOR BASED TRANSMISSION CLOCK CONTROL - A system and method is provided for phase interpolator based transmission clock control. The system includes a transmitter having a phase interpolator coupled to a master timing generator and a transmission module. The phase interpolator is also coupled to a receiver interpolator control module and/or an external interpolator control module. When the system is operating in repeat mode, the transmitter phase interpolator receives a control signal from a receiver interpolator control module. The transmitter phase interpolator uses the signal to synchronize the transmission clock to the sampling clock. When the system is operating in test mode, a user defines a transmission data profile in an external interpolator control module. The external interpolator control module generates a control signal based on the profile. The transmitter phase interpolator uses the signal to generate a transmission clock that is used by the transmission module to generate a data stream having the desired profile. | 01-12-2012 |

| 20080225810 | CONFIGURABLE ZONE-BASED LOCATION DETECTION - An improved technique provides location detection using wireless net-works such as Wi-Fi networks in a flexible, configurable manner that allows for variations in the environment and tracks target movement accurately in such an environment. Zones of different relative sizes and sensitivities can be defined, so as to vary the degree of resolution for different parts of the area being detected. Mechanisms are provided to take into account fluctuations in signal strength, and reduce the incidence of false positives resulting from incorrectly detecting zone or location changes due to fluctuations of signal strength. In addition, detection time can be configured for zone entry and/or exit. Self-adjustment based on heuristic analysis can also be implemented. Data can be sent or received based on the physical location as determined by the zone. | 09-18-2008 |
