Patent number: 9647606Abstract: An apparatus for measuring movement of an object has a quadrature incremental encoder for providing first and second phases of encoder pulses corresponding to incremental displacements of the object. A first counter counts edges of the encoder pulses according to the sense of the displacement. Clock pulse counts are also made. Acquiring movement data at periodic speed processing moments includes the decoder adjusting encoder pulse data from the first counter using a clock pulse count that is a function of a lapse of time between when the most recent edge of the encoder pulses and the speed processing moment. The clock pulse counts are reset by edges of the first and second phases of the encoder pulses when the decoder acquires the movement data.Type: GrantFiled: October 20, 2015Date of Patent: May 9, 2017Assignee: FREESCALE SEMICONDUCTOR, INC.Inventors: Shunan Li, Xuwei Zhou, Wanfu Ye

Patent number: 8050730Abstract: The present invention discloses a method and apparatus for eliminating interference in pulse oxygen measurement. The method comprises the steps of: collecting a first wavelength light and a second wavelength light transmitting through the object to be measured and converting collected optic signals into electric signals to form a plethysmogram; processing the plethysmogram so as to normalize it, in order to decompose the normalized plethysmogram into a combination of an ideal plethysmogram and noise, and expand the ideal plethysmogram by using functions that can make up a complete orthonormal system; eliminating the noise in the plethysmogram through differential operation; and restoring the plethysmogram free of noise through integral operation for calculating oxygen saturation. The apparatus comprises a collecting module, a processing module, a noise eliminating module, and a restoring module.Type: GrantFiled: September 18, 2006Date of Patent: November 1, 2011Assignee: Shenzhen Mindray Bio-Medical Electrics Co., Ltd.Inventors: Xu Zhang, Xu Li, Shunan Li
