Publication number: 20210131899Abstract: A digital pressure sensor includes a substrate, a pressure sensing structure configured for measuring a pressure of an object to be measured, a signal processing chip configured for receiving a sensing signal of the pressure sensing structure, and a rubber cover having an opening through which the pressure is sensed. The pressure sensing structure and the signal processing chip are mounted on the substrate. The signal processing chip has an analog-digital conversion module that converts the sensing signal output by the pressure sensing structure into a digital signal and outputs the digital signal. The signal processing chip is electrically connected to the substrate. The substrate and the rubber cover are connected to each other and form a mounting cavity for holding the pressure sensing structure and the signal processing chip.Type: ApplicationFiled: October 30, 2020Publication date: May 6, 2021Applicants: Measurement Specialties (China ) Ltd., Measurement Specialties, Inc.Inventors: Yang Zhai, Xu Liang, Jianjie Yuan, John Valentini, Bala Kashi

Patent number: 10995900Abstract: The present invention relates to a vertical floor self-locking musical instrument stand and a self-locking hook. The vertical floor self-locking musical instrument stand is provided with a plurality of folding structures, which can facilitate telescopic storage and reduce the occupied space. The telescopic length can be changed as needed to be portable. Various components are flexibly connected and assembled. The height of the position can be adjusted as needed. The stand is equipped with a folding anti-collision component and a self-locking hook, which can better protect the musical instrument and prevent the musical instrument from bumping or falling. When the musical instrument is suspended on the self-locking hook, the self-locking hook automatically locks the self-locking locking arm under the gravity of the musical instrument itself, providing protection for the musical instrument suspended thereon.Type: GrantFiled: June 23, 2020Date of Patent: May 4, 2021Inventors: Sen He, Xu Liang

Publication number: 20210056948Abstract: An acoustic focusing probe, which is an artificial periodic acoustic structure, including a background material which is water or air, and a plurality of scatterer units in a cross shape. The periodic array structure formed by scatterer units is arranged on the base, and a contour thereof is an ellipse. The present invention is based on the basic principle of controlling acoustic waves by phononic crystal and adopts a new probe structure. Compared to the existing acoustic focusing lens, the acoustic focusing probe of the present invention has a better acoustic focusing effect in various media and a wider range of low and medium frequencies. The probe can focus most of the energy of the acoustic waves to the target area, and thus it can be used in non-invasive ultrasound equipment in the future.Type: ApplicationFiled: August 21, 2019Publication date: February 25, 2021Inventors: Xu LIANG, Yongdu RUAN, Lizhong WANG, Yuhong WANG, Titao WANG, Yu DENG

Patent number: 10671924Abstract: In one embodiment, a computer-implemented method includes receiving training data including a plurality of records, each record having a plurality of attributes. The training data is horizontally parallelized across two or more processing elements. This horizontal parallelizing includes dividing the training data into two or more subsets of records; assigning each subset of records to a corresponding processing element of the two or more processing elements; transmitting each subset of records to its assigned processing element; and sorting, at the two or more processing elements, the two or more subsets of records to two or more candidate leaves of a decision tree. The output from horizontally parallelizing is converted into input for vertically parallelizing the training data. The training data is vertically parallelized across the two or more processing elements. The decision tree is grown based at least in part on the horizontally parallelizing, the converting, and the vertically parallelizing.Type: GrantFiled: August 24, 2015Date of Patent: June 2, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Wei Shan Dong, Peng Gao, Guo Qiang Hu, Chang Sheng Li, Xu Liang Li, Chun Yang Ma, Zhi Wang, Xin Zhang
