Abstract:
The subject matter disclosed herein relates to a system and method for processing multiple navigation signal components received from multiple global navigation satellite systems (GNSS'). In a particular implementation, an energy detection in a first navigation signal component is classified based, at least in part, on information in a second navigation signal component.
Abstract:
The subject matter disclosed herein relates to a system and method for determining a sufficiency of measurements for locating positions. In one example, although claimed subject matter is not so limited, a process to improve accuracy of pseudorange measurements may be terminated in response to a weighting of quantitative assessments of at least some of such pseudorange measurements.
Abstract:
Methods and apparatus for code phase processing in a wireless communication device are described herein. A wireless device performs code phase search on a pseudo random code spread signal received over a wireless channel. A correlator correlates the received signal to a plurality of code phases in each of a plurality of frequency hypothesis. A maximum peak and a second peak are determined from the correlation results. Cross correlation processing is performed on the maximum peak and the maximum peak is discarded in favor of the second peak for position processing based on the results of the cross correlation.
Abstract:
Methods and apparatus are provided for use in devices adapted to receive signals from at least one satellite positioning system (SPS). As part of at least one search for a transmission from a space vehicle (SV) associated with the SPS, the methods and apparatuses may correlate a code associated with the SV with a received signal to establish a plurality of correlation values, sample at least a portion of the correlation values during the search, and selectively transitioning the search early or prematurely based, at least in part, on at least one of the sampled correlation values.

An apparatus and method for cross-correlation spur mitigation comprising choosing from a plurality of peak measurements, a first peak measurement with a first carrier-to-noise density estimate and a first Doppler offset measurement, and a second peak measurement with a second carrier-to-noise density estimate and a second Doppler offset measurement to form a pair; calculating a carrier-to-noise density difference based on the first carrier-to-noise density estimate and the second carrier-to-noise density estimate; calculating a Doppler difference based on the first Doppler offset measurement and the second Doppler offset measurement; comparing the carrier-to-noise density difference to a carrier-to-noise density threshold; and comparing the Doppler difference to at least one Doppler threshold.
Abstract:
A flash memory system including a flash memory device and a controller, operable according to an advanced data transfer mode is disclosed. The flash memory device is operable both in a "legacy" mode, in which read data is presented by the memory synchronously with each cycle of a read data strobe from the controller, and in which input data is latched by the memory synchronously with each cycle of a write data strobe from the controller. In the advanced mode, which can be initiated by the controller forwarding an initiation command to the memory, data is read at a higher frequency, for example at twice the frequency, of that available in the normal mode. In the advanced mode, the input data is presented by the controller at a higher frequency than is available in the normal mode. The voltage swing of the data and control signals is reduced from conventional standards, to reduce power consumption.

Some embodiments include methods for customizing operation of the robotic vehicle for an operator. Such embodiments may include identifying a current operator of the robotic vehicle, configuring the robotic vehicle based on metadata associated with an operator profile for the operator, determining whether the operator has changed, and if so, identifying the new operator, deriving updated preference-based settings and performance-based settings for the new operator, and updating configurations of the robotic vehicle accordingly. Some embodiments may include identifying a current operator, retrieving an operator profile and associated metadata for the operator from a central database, configuring the robotic vehicle based on preference-based and performance-based settings, analyzing input data during operation, storing identified real-time operator habit information during operation of the robotic vehicle, deriving updated preference-based and performance-based settings for the operator; and uploading to the central database modifications to the metadata associated with the operator profile of the operator.
