Abstract: A speaker box includes a housing with an accommodating space and a housing wall; a propping wall extending from the housing wall toward the accommodating space; and a speaker unit located between the housing wall and the propping wall for dividing the accommodating space into a front cavity and a back cavity. The speaker unit includes a diaphragm located in the front cavity for forming a front sound cavity cooperatively with the housing, a sound guiding channel communicating the front sound cavity with outside, and a through hole penetrating the propping wall and communicating the sound guiding channel with the back cavity. The speaker box further includes an elastic cover plate covering the through hole completely for absorbing vibration energy at a specific frequency. The Young's modulus or strength of the elastic cover plate is smaller than that of the propping wall.

Abstract: Technical solutions are described herein for position estimation of permanent magnet synchronous machines through vibration induced saliency. An example permanent magnet synchronous machine (PMSM) includes a motor control system to provide input command to the motor to cause a position of the motor to change. The PMSM further includes a motor position estimation module configured to estimate the position of the motor. The estimation includes measuring a current Iabc across the motor. The estimation further includes extracting a filtered current Iabc_inj at a predetermined frequency from the current Iabc. The estimation further includes estimating the position of the motor based on the filtered current Iabc_inj.

Abstract: An approach is provided that receives a question at a question answering (QA) system. The question includes a number of words. The approach operates by calculating weights that correspond to search terms included in the plurality of words. The search terms include the plurality of words and may include terms that are one or more sequences of adjacent words included in the question. Based on the calculated weights and the words in the question, the approach generates a query that is used to search a corpus that is managed by the QA system with the search resulting in one or more search results.
