Patent number: 8837798Abstract: A time domain signal analysis method is provided. The signal analysis method includes the following steps. A signal to be analyzed is received. The signal to be analyzed is iteratively sifted by using Empirical Mode Decomposition (EMD) to extract at least one intrinsic function (IMF). A normalized Hilbert transform is performed on the IMF. The transformed IMF includes phase information. The transformed IMF is processed by means of phase processing to obtain the processed IMF including angular frequency information. The foregoing signal analysis method could be utilized in an ultrasound imaging system to identify image information of ultrasound images.Type: GrantFiled: July 19, 2012Date of Patent: September 16, 2014Assignee: Industrial Technology Research InstituteInventors: Arvin Huang-Te Li, Yio-Wha Shau, Yu-Ching Chang, Bai-Kuang Hwang, Min Shih

Patent number: 8744128Abstract: An image processing method is provided. The image processing method includes the following steps. A plurality of raw signal is received by a signal transceiving module of the ultrasound imaging system. It is determined whether each of the raw signals satisfies any condition in a condition group, and the raw signal satisfying any condition in the condition group is mapped to one of a plurality of preset constants to generate a plurality of first data. The raw signals not satisfying any condition in the condition group are processed according to a calculation formula to generate a plurality of second data. A beamforming procedure is simultaneously performed on the first and second data to obtain a beamformed image. The beamformed image is transformed to obtain an image of a region to be detected. Furthermore, an imaging system using the foregoing image processing method is also provided.Type: GrantFiled: July 26, 2012Date of Patent: June 3, 2014Assignee: Industrial Technology Research InstituteInventors: Arvin Huang-Te Li, Yio-Wha Shau, Yu-Ching Chang, Bai-Kuang Hwang

Publication number: 20120325019Abstract: A force sensing device and a force sensing system are provided. The force sensing device comprises at least one magnetic material layer and a force sensing layer which can move with respect to each other. The force sensing layer comprises two sensing elements. The first sensing element, disposed along a first axis of the magnetic material layer, generates a sensing signal varying with a first lateral force applied on the force sensing device. The first lateral force enables the first sensing element to move relatively with respect to the magnetic material layer along the first axis. The second sensing element, disposed along a second axis of the magnetic material layer, generates a sensing signal varying with a second lateral force applied on the force sensing device. The second lateral force enables the second sensing element to move relatively with respect to the magnetic material layer along the second axis.Type: ApplicationFiled: October 24, 2011Publication date: December 27, 2012Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Yio-Wha Shau, Arvin Huang-Te Li, Gaung-Hui Gu, Bai-Kuang Hwang, Jen-Chieh Lin
