Abstract: Aspects of the subject disclosure may include, for example, an inner clock generation circuit, including: a selectable frequency divider having: a ring of tri-state inverters; a reset gate on an output of each tri-state inverter in the ring; and a reset circuit comprising one or more selectable flip-flops; and a duty-cycle limiter that generates clock signals having a 25% duty cycle from three out of four quadrature clock signals. Other embodiments are disclosed.

Abstract: A meta-search system for performing a search over a plurality of data sources via one or more search passes, the system comprising: a search controller for: i) transmitting a search query object having a specified route which lists a plurality of query processors desired to be executed; ii) receiving data request objects from the plurality of executed query processors and transmitting the data request objects to a plurality of data collectors, each data request object being transmitted to associated data collector, iii) receiving result objects associated with the data requests from the data collectors, and iv) transmitting the result objects to a user interface for display; the plurality of query processors being executed according to the specified route to receive and process the search query object, each of the query processors enabled to generate a data request object based on the search query object and one or more data request objects generated by one or more previously executed query processors; and ea

Abstract: A search system has a plurality of resources, including data resources and query and result processing resources. The search system determines the selection and ordering of resources at run-time through a combination of pre-defined default rules and a search strategy that is associated with each search.
