Abstract: A computer-implemented method for aligning a sensor to reference coordinate system includes initiating a plurality of threads, each thread executes simultaneously and independent of each other. A first thread parses data received from the sensor and stores the parsed data in a data buffer. A second thread computes an alignment transformation using the parsed data to determine alignment between the sensor and the reference coordinate system. The computing includes checking that the data buffer contains at least predetermined amount of data. If at least the predetermined amount of data exists, an intermediate result is computed using the parsed data in the data buffer; otherwise, the second thread waits for the first thread to add more data to the data buffer. The second thread outputs the intermediate result into the data buffer. A third thread outputs the alignment transformation, in response to completion of alignment computations.

Abstract: The invention describes a two-phase steel comprising 8-12 wt. % Mn, 0.3-0.6 wt. % C, 1-4 wt. % Al, 0.4-1 wt. % V, and a balance of Fe. The steel has martensite and retained austenite phases, and may include vanadium carbide precipitations. A method for making the two-phase steel involves the steps of (a) hot rolling the ingots of the composition to produce a plurality of thick steel sheets, (b) treating the steel sheets by an air cooling process, (c) warm rolling the steel sheets at a temperature in the range of 300-800° C. with a thicknesses reduction of 30-50%, (d) annealing the steel sheets a first time at a temperature in the range of 620-660° C. for 10-300 min, (e) cold rolling the steel sheets at room temperature with a thickness reduction of 10-30% to generate hard martensite, and (f) annealing the steel sheets a second time at a temperature in the range of 300-700° C. for 3-60 min to facilitate the partitioning of carbon and release the residual stress n martensite.

Abstract: A strong and ductile automotive steel comprising 8-11 wt. % Mn, 0.1-0.35 wt. % C, 1-3 wt. % Al, 0.05-0.5 wt. % V, and a balance of Fe. By tuning the amount of austenite stabilizers, a dual phase microstructure of martensite and austenite with proper phase fraction can be achieved at room temperature. The martensite partitions C into the retained austenite grains. The martensite matrix can ensure the higher strength of automotive steel while the retained austenite grains with varied mechanical stability can improve the ductility of automotive steel, achieving the strength of 1500 MPa and the ductility of 20% simultaneously. The method for fabricating this automotive steel circumvents the high quenching temperature of conventional Q&P steels and therefore reduces the production price and is easy for mass production.
