摘要:
A manipulator for a fiber optic cable assembly (FOCA) provides microradian accuracy in control of the direction of a beam emanating from the FOCA. Such manipulators can control FOCAs to control the incidence angles of beams at a beam combiner in a beam-combining unit. Accordingly, fewer additional optical elements are required for control of input paths in the beam-combining unit. The manipulator and the beam-combining unit are accurate enough for use in an interferometer that combines beams with different frequencies and polarizations. One such interferometer includes a Zeeman split laser providing a heterodyne beam. A beam splitter separates frequency components of the beams, and AOMs increase the frequency separation between the separated beams. The separated beams can be sent via optical fibers to the beam-combining unit, which combines the beams for use in interferometer optics.

The rocker arm assembly has an anti-inversion part that prevents a support pin from inverting, ensuring proper orientation of the support pin, on which a rocker arm is rotatably mounted, is maintained. The anti-inversion part can be a washer, a plate, a plug, or a sleeve. The washer, which has a flat face and a curved face, is intended for use with a cylindrical support pin which matches the curved face of the washer. The plate can include various combinations of tabs, flanges, and/or protrusions that extend in different directions. The plug can resemble any desirable shape, and is removed prior to final assembly. The sleeve can be hollow and is removable.

Methods and systems for interactive evolutionary computing may include generating a set of candidate molecules based on an evolutionary scheme in which an objective function is a priori mathematically unexpressed, presenting data based on the set of candidate molecules to one or more users, receiving at least one input from the user(s), the input(s) based on the user(s)'s evaluation of the presented set of candidate molecules, and, based on the input(s), using at least the evolutionary scheme and the input(s) to generate an updated set of candidate molecules, and repeating the presenting and receiving.

A distributed digital media metering and reporting system makes available digital media files for multiple consumer devices from a computer-based infrastructure. The consumer devices meter the number of playbacks of a media file that last beyond a predefined extent, in order to generate metering data, and then automatically report that metering data back to the computer-based infrastructure.

A mobile wireless device includes an embedded media player; the functionality of the media player has been extended by integrating a third party application with the media player, the third party application supporting an unlimited music subscription service. Hence, the invention is based on the insight that a third party application that can provide access to an unlimited music subscription service, such as the MusicStation media player, can be integrated with an embedded media player in a mobile wireless device. The device then behaves as though the functionality of the media player has been extended, but without the extensive engineering effort needed to re-write the embedded media payer so that it can itself provide access to the unlimited music subscription service.

A geographic tracking system with minimal power and size required at the mobile terminal collects observation data at the mobile terminal, forwards the data to a processor, which calculates the position. The mobile terminal needs only to gather a few milliseconds of observation data, and to relay this observation data to the processor. The range from the satellite (or other airborne transponder) to the terminal is determined using the known positions of an interrogating transmitter and a satellite, and a known terminal delay between the received signal and the transmission of the return signal, and the round trip time. An arc of locations is determined by computing an intersection of a sphere centered at the satellite having a radius given by the calculated range with a model of the Earth's surface. The candidate points are considered and refined using code phase measurements from a set of GPS satellites. The candidate point having the lowest residuals or expected to measured code phases is chosen as the location of the mobile terminal. The measurements can be refined to account for various sources of error including measurement bias, relative motion and timing errors.
