Publication number: 20140249424Abstract: Factor retrieving is a major approach for pulse wave analysis. Stiffness index and cardiac output are widely used factors for cardiac risk detection. Research has been done on clinical pulse wave data which are collected by pulse oximeter. The result shows that collected factors have a positive correlation with certain cardiac risks. Some adjustments have been applied on the algorithms that increase the significance. In addition to the factor based analysis, other signal processing techniques for pulse waveforms are included such as bispectrum estimation, Wavelet transform, and weighted dynamic time warping. Bispectrum estimation and Wavelet transform have meaningful features of pulse waveforms with some special shapes. Weighted dynamic time warping compares the similarity of waveforms. It also includes medical significance into the calculation by adjusting the weight vector. This algorithm has higher accuracy when providing more samples to compare.Type: ApplicationFiled: December 4, 2013Publication date: September 4, 2014Applicant: University of WinnipegInventors: Zhaopeng Fan, Michael Gong Zhang, Simon Xin Meng Liao

Publication number: 20080092678Abstract: A dust-proof structure for a ball screw comprises: a wiper, a wiping piece and a fastening device. The wiper is a C-shaped structure defined with a gap for accommodation of a wiping piece and is annually mounted on a surface of a screw shaft. The wiper is formed at either side of the gap with a bevel surface, and the wiping piece is also formed at both sides thereof with a bevel surface for mating with the bevel surface of the gap, so that the wiper and the wiping piece are maintained into contact via the bevel surfaces. The fastening device enables the C-shaped wiper to be deformed in radial direction, making the wiping piece abut against the surface of the screw shaft. By such arrangements, an interacting force between the bevel surfaces of the wiping piece and the wiper pushes the wiping piece toward the surface of the screw shaft, thus effectively preventing dust.Type: ApplicationFiled: August 22, 2006Publication date: April 24, 2008Inventors: Chi-Meng Liao, Chia-Min Liu
