Abstract: A method of determining an effect of wind on a flight path of a golf ball includes predictive modeling a flow of air through a null terrain with a processing system. The null terrain includes a three-dimensional digital model of a physical terrain and a physical feature. Changes of a wind speed, a wind direction, or a combination thereof of the flow of air are calculated with the processing system based on the predictive modeling of the wind speed and the wind direction through the null terrain. An output data set of predicted wind behavior is generated based on the calculated changes of wind speed, wind direction, or a combination thereof of the flow of air through the null terrain. An effect of wind behavior on the flight-path of the golf ball is predicted based on the output data set of predicted wind behavior.

Abstract: Methods and apparatus for performing dynamic channel selection are provided. In an example, a method includes receiving, at a central self-organizing network server, data from an access point (AP) including a number of stations associated with the AP. The method includes calculating downlink capacities for the associated stations and selecting a channel for the AP which maximizes a pre-defined network utility that is based on the downlink capacities. Further, it is determined if the network utility gain resulting from selecting the channel exceeds a threshold when compared to a previous channel selection state. If the network utility gain exceeds the threshold, a channel change command is issued to the AP, directing the AP to use the selected channel to communicate with a specific station.

Abstract: An adaptive filter bank can be implemented on a PLC device to dynamically adapt to variations in notching requirements and the performance of the PLC medium. The PLC device can apply filter coefficients to one or more filter elements of the adaptive filter bank to generate one or more notched subcarriers in the PLC band. A performance measurement of one or more subcarriers in the PLC band can be determined and evaluated against corresponding performance measurement thresholds. For a given notched subcarrier, if the performance measurement of the corresponding subcarriers is not in accordance with the performance measurement threshold, updated filter coefficients for the filter element configured to generate the notched subcarrier can be determined based, at least in part, on the performance measurement of the one or more subcarriers. The filter coefficients of the filter element can then be updated using the updated filter coefficients.

Abstract: A measurement method and apparatus rely upon the coherent optical interference between a reference beam and a diffractionless sensing beam having an optical path length that has been disturbed. The interference pattern can be analyzed to determine a measurement parameter of the disturbance. The diffractionless beam is particularly a Bessel beam. Exemplary optical interferometer types including Mach-Zehnder, Michelson, Sagnac and Fabry-Perot include a Bessel beam generator to generate a diffractionless beam as the sensing optical beam and in some aspects the reference optical beam of the interferometer. The sensing optical beam propagates along a sensing optical beam path in free-space. The reference optical beam path may be a free-space medium or a material medium such as an optical fiber. The sensing optical beam path is subject to a disturbance manifested by the optical interference pattern between the sensing optical beam and the reference optical beam.
