Abstract: Methods and systems for stabilizing a GNSS clock by reducing interference are disclosed and may include stabilizing a frequency of a temperature compensated crystal oscillator (TCXO) on a chip in a GNSS device. A clock signal may be generated for the device by temporarily configuring circuitry adjacent to the TCXO at a constant power level.

The frequency of the TCXO may be stabilized by temporarily disabling the adjacent circuitry. A GNSS clock signal may be stabilized by the configuring of the constant power level while a GNSS location may be calibrated. A GNSS location of a fixed wireless device, such as a wireless access point, may be calibrated utilizing the configured constant power level and shared with other wireless devices.

Abstract: Methods and systems for using algorithms in relational database management systems (RDBMSs) for incremental maintenance of materialized views with outerjoins are disclosed. The algorithms achieve the following goals with respect to a class of materialized outerjoin views and the performance of update operations: relax the requirement for the existence of the primary key attributes in a select list of the view to only some of the relations (i.e., the relations referenced as a preserved side in an outerjoin); relax null-intolerant property requirements for some predicates used in the view definition (i.e., predicates referencing relations which can be null-supplied by more than one outerjoin); and implement maintenance of outerjoin views by using one update statement (e.g., MERGE, UPDATE, INSERT, or DELETE) per view for each relation referenced in the view. The algorithms allow design and implementation of the incremental maintenance of materialized views with outerjoins to be integrated into an RDBMS.

Abstract: A method and system for advanced media access control delegated from a host device, such as a WiFi device, to a smart wireless communications module. In an embodiment, the host signals to the wireless module a list of one or more preferred networks.

In either case, the wireless communications module may monitor the wireless environment, and scan for preferred networks, in parallel with maintaining an existing connection. The method and system allows rapid adaptation to a changing network environment, and enables lower system power consumption by distributing management functions between the host and the lower-powered wireless communications module.
