Abstract: Systems and methods are provided for implementing URL embeddings for aligning parallel documents that are corresponding web pages in at least two different languages. A computing system uses a pre-trained model of an AI system to calculate URL embeddings for each URL among a plurality of URLs. The system identifies, based on closeness of the points represented by the URL embeddings, a set of candidate parallel URLs by analyzing the URL embeddings for the plurality of URLs or for a second plurality of URLs that has been partitioned into a cluster, using a clustering algorithm. A set of parallel URLs, associated with the parallel documents, is selected from the identified set of candidate parallel URLs. Document text and/or parallel sentences are extracted from web documents associated with the set of parallel URLs to train a machine translation model for translating between two or more languages.

Abstract: Technology described in this document can be embodied in a system for detecting analytes in a biochemical sample. The system includes a container configured to contain the biochemical sample. The system also includes a light source, an optical detector, a lens, and an optical aperture. The lens is disposed between the container and the optical detector, and the optical aperture is disposed between the lens and the optical detector. The system further includes a structure configured to house the container, the optical aperture, the lens, and the optical detector.

Abstract: Methods and devices for anticipating a surge in a gas turbine engine. Controlled pressure signal(s) may be compared with reference pressure signal(s), each of the controlled pressure signal(s) and reference pressure signal(s) having an associated time value. If the controlled pressure signal(s) are less than the reference pressure signal(s), a controlled pressure curve may be fitted through a predetermined number of points based on the controlled pressure value(s) and associated time value(s). A reference pressure curve may be fitted through the predetermined number of points based on the reference pressure value(s) and associated time value(s). A time to compressor surge may be estimated based on an intersection of the controlled pressure curve and the reference pressure curve.

Abstract: A lubrication system for an aircraft engine includes a lubrication fluid tank and a fluid passage communicating with the tank to define an entry of the passage inside the tank. The entry is positioned in a location submerged in the lubrication fluid for delivery of the lubrication fluid under a pressure differential, from the tank to the lubrication system regardless of the tank or aircraft attitude.

Abstract: A gravity controlled lubrication system for aircraft engines to supply a lubricant from a tank to a circulating system permitting lubricant to flow when the aircraft changes to an inverted flight condition.

Abstract: Methods of and apparatuses for characterizing the power supplying capabilities of host power supplies providing power to wireless modems. According to an exemplary method, an equivalent series resistance of the power supply is determined and compared to a plurality of maximum equivalent series resistance values associated with a corresponding plurality of transmission power classes. Each power class is designated as a permissible power class at which the wireless modem may be configured to transmit, for each maximum equivalent series resistance value that is greater than the equivalent series resistance of the power supply.

Abstract: A method and apparatus for suppressing noise caused by the switching of a switching power supply. The method and apparatus use frequency dithering techniques to distribute the switching noise and its spurious products over a wider bandwidth, thereby reducing the average peak power per given range of bandwidth. The frequency dithering techniques are particularly applicable to mobile radio applications, where switching noise from switching power supplies can modulate the transmit carrier and its harmonics, sub-harmonics and intermediate frequency products.
