US11831123B2	SBS suppression and electronic path length matching in coherent beam combining In coherent beam combining, the beams can be phase-modulated with a pseudo-random bit sequence (PRBS) to prevent stimulated Brillouin scattering (SBS) downstream. To coherently combine the phase-modulated beams, however, the PRBS waveforms should be true-time-delayed to within a small fraction of the bit duration. Traditionally, this true time delay is achieved by cutting optical fibers to length or with optical trombones. But trimming fibers is hard to do precisely, and optical trombones have large insertion loss. In addition, the path length mismatch varies as the fibers heat up and/or vibrate. Here, the beams are generated from a kilohertz linewidth seed split among N>1 (e.g., N=100) arms. Each arm is phase-modulated with a separate copy of the unique PRBS pattern. The relative phase of the PRBS patterns is stabilized by phase-locking the master oscillators used to read out the PRBS patterns. The PRBS patterns can be phase shifted with respect to one another to compensate for physical path length mismatches of the optical fibers. Scanning the relative phase of the PRBS pattern used to modulate different arms yields a cross-correlation peak in combined power when the phases are matched at the combination plane.

US11831028B2	Secondary battery A secondary battery including: a case including an opening; a top cover assembly including a top cover plate covering the opening and an electrode terminal, the top cover plate including an electrode lead-out hole corresponding to the electrode terminal; an electrode assembly received in the case and including a main body and a tab, the tab being bent relative to a thickness direction of the top cover plate to form a bent portion; and a current collecting wiring board disposed between the top cover plate and the main body and including a first connection portion, a second connection portion, and a transition portion, the first connection portion and the second connection portion extending along a width direction of the top cover plate and being provided opposite to each other, the first connection portion being connected with the electrode terminal, and the second connection portion being connected with the bent portion.
US11831025B2	Catalyst, preparation method therefor, electrode comprising same, membrane-electrode assembly, and fuel cell A catalyst, a preparation method therefor, an electrode containing the catalyst, a membrane-electrode assembly, and a fuel cell are disclosed. The catalyst contains a support; metal particles supported by the support; and a coating layer located on the metal particles, and includes any one selected from the group consisting of phthalocyanine, M-phthalocyanine (wherein M is a transition metal) and a mixture thereof. The catalyst has improved durability since a coating layer is formed on the surface of a commercial catalyst or a conventional catalyst through a relatively easy method without separate treatment. A carbon coating layer formed by post-treating a catalyst including the coating layer further improves durability. Material transfer ability and performance are also improved by a carbon nanofiber or a carbon nanotube generated during post-treatment.
US11831024B2	Polymer current collector, preparation method thereof, and secondary battery, battery module, battery pack, and apparatus associated therewith This application provides a polymer current collector, a preparation method thereof, and a secondary battery, battery module, battery pack, and apparatus associated therewith.
