Abstract: Illustrative embodiments of reconfigurable microwave filters, as well as associated systems and methods, are disclosed. In at least one illustrative embodiment, a reconfigurable microwave filter may comprise a plurality of cavity resonators on a common substrate and a plurality of control circuits each configured to control a resonant frequency of one of the plurality of cavity resonators. The reconfigurable microwave filter may also comprise a plurality of feedback circuits each configured to generate a feedback signal that is indicative of the resonant frequency of one of the plurality of cavity resonators and to transmit the feedback signal to one of the plurality of control circuits.

Abstract: Methods and apparatus are provided for determining market statistics for communication service providers. Determinations of whether or not a sampling of telephone numbers are assigned by a particular service provider are employed to determine market statistics. A message which is used to obtain a response. The response is interpreted to determine whether or not the telephone number associated with the wireless device is assigned. Alternatively, a sampling of telephone numbers are dialed over a digital line. Based upon the result of the dialing, it is determined whether or not the telephone numbers are assigned by the service provider. Telephone numbers which have been ported between service providers in networks which employ local number portability can be accounted for in the determination of market statistics. A telephone number portability database can also be employed for determining whether or not a telephone number is assigned by a service provider.
