摘要： In a local positioning system, augmentation of the land-based system is provided by receiving signals from a GNSS. The signals from the land-based positioning system have a code phase accuracy better than one wavelength of a carrier of the signals from the GNSS. Different decorrelation may be used for signals from a satellite than from a land-based transmitter, such as using a digital decorrelator for signals from the satellite and an analog decorrelator for signals from a land-based transmitter. The receivers may include both a GNSS antenna and a local antenna. The phase centers of the two antennas are within one wavelength of the GNSS signals from each other. The local antenna is sized for operation in the X or ISM-bands of frequencies. The GNSS antenna is a patch antenna where the microwave antenna extends away from the patch antenna in at least one dimension.

摘要： A method and structures are provided for implementing customizable dielectric printed circuit card traces. A void is defined near selected signal traces. The void is then filled with a dielectric material having a predefined dielectric property. The dielectric material is selected to alter at least one predefined electrical property of the selected signal traces, such as, coupling, propagation delay and attenuation. In one embodiment, an outer layer of a printed circuit card includes a plurality of signal traces and a mating circuit card layer including a plurality of matching signal traces is attached to the outer layer of the printed circuit card to create a cavity near selected signal traces. The cavity is filled with the selected dielectric material. In another embodiment, dielectric material is selectively removed near signal traces on an outer layer of the printed circuit card to define a void near selected signal traces.

摘要： Vertical and horizontal wind shears, yaw misalignment and/or turbulence act together to produce asymmetric loading across a wind turbine rotor. The resultant load produces bending moments in the blades that are reacted through the hub and subsequently to the main shaft. As a result, the main shaft may be radially displaced from its at rest positions. The amount of radial displacement is measured using two or more sensors. The output signals from the sensors are used to determine the magnitude and/or the orientation of the resultant rotor load. This information is used to affect the blade pitch change or other action with similar system effect to reduce the asymmetric load and thereby reduce fatigue and loading on various turbine components.

摘要： A method and system for delivering a subpoena via an electronic subpoena service. The electronic delivery can constitute legal service of the subpoena or be accompanied by hardcopy service. Utilization of a system to serve subpoenas can provide timely and efficient service with an automated audit trail. The system can enable broad service with confirmed identification of relevant parties to be served. An automated search of electronic records provides uniform search criteria for compliance, even with multiple locations and subsidiaries, including foreign subsidiaries.

摘要： Methods and receivers determine a range from radio frequency ranging signals at multiple frequencies. The number of dedicated RF sections and correlation processing power is reduced by multiplexing signals from a sub-set of frequencies onto a common path. The common path provides shared processing, such as down-conversion shared by signals at two different frequencies. The correlation processing power for a three frequency receiver may be the same or similar as for a two frequency receiver since signals for two frequencies share processing as a function of time. Correlation is performed intermittently for signals at two of the frequencies.

摘要： Data throughput rate in a power line communications (“PLC”) system is controlled by generating PLC carrier signals in accordance with a PLC signal frame structure containing payload symbols where the payload symbol length is selected based on at least one of a PLC system channel quality and node configuration data. The selected payload symbol length determines the processing operations that a source PLC transceiver performs for generating PLC signals or that a destination PLC transceiver performs for extracting information content from received PLC signals. The payload symbol lengths can be selected to maximize the data throughput rate while maintaining compatibility with prior art PLC system protocols and standards that require a PLC signal frame structure and its payload portion to have fixed, predetermined lengths.
