20100067746 | OPTICAL MOTION SENSING PROCESS - A motion sensing process senses a mouse moving relative to a surface by taking a reference image and a sample image of the surface. The process shifts the reference image to neighboring pixel positions arranged in certain patterns and compares the sample image with the reference image at its original pixel position at the shifted pixel positions. A motion vector describing a displacement of the object with respect to the surface is generated from such comparisons. In one embodiment, the pattern includes the original pixel position and neighboring pixel position arranged five rows and five columns with the total number of the pixel positions less than twenty five. In another embodiment, the process selects one of four elongated patterns based on the orientation of a predicted motion vector. In yet another specific embodiment, the process selects one of eight directional patterns based on the direction of the predicted motion vector. | 03-18-2010 |
20100325793 | EXAMINATION BED MOVEMENT DEVICE - An examination bed horizontal movement device including an examination bed, an examination bed connector fixed at the bottom of the examination bed, a support board and a fixed board is provided. Two tension wheels are installed at the front and back ends of the support board separately, and the two tension wheels are connected by an examination bed conveyor belt. A tension wheel and a driving wheel are fixed at both ends of the fixed board, and the tension wheel and the driving wheel are connected by a support board conveyor belt. A driving wheel is installed coaxially on the fixed board tension wheel, and the examination bed conveyor belt winds around the driving wheel. The movement device achieves a compact design of the horizontal structure for the examination bed in a strong magnetic field MRI system and provides long travel and highly repeatable positioning accuracy of the horizontal movement. | 12-30-2010 |
20110041633 | VERTICAL MOVEMENT DEVICE FOR AN EXAMINING TABLE - A vertical movement device for an examining table includes a driving wheel, a nut and screw pair and a direction-converting synchronization belt. The driving wheel is disposed on the examining table. The rotation axis of the nut is perpendicular to the rotation axis of the driving wheel, and the nut moves vertically on the screw when the nut rotates so as to carry the examining table to move vertically. The direction-converting synchronization belt converts the rotation of the driving wheel into the rotation of the nut so as to realize the vertical movement of the examining table. The self-locking vertical movement device reduces the noise and manufacturing costs, simplifies the structure, increases the maximum lifting weight and speeds up the lifting/lowering process. | 02-24-2011 |
20110254770 | OPTICAL DEVICE - An optical device comprises an outer case including a light transmitting work area, an optical lens inside the outer case, and an optical sensor device inside the outer case, wherein an imaging pathway from the work area through the optical lens to the optical sensor device is non-perpendicular to the work area. | 10-20-2011 |

20130205926 | PUSH CHAIN, LINEAR MOTION DRIVING DEVICE AND PATIENT TABLE - A push-chain includes a plurality of push-chain links, each push-chain link of the plurality of push-chain links including two strip-shaped mounting pieces disposed opposite one another and one connecting piece that connects at most half of an end face of the two mounting pieces at one side. Each of the two mounting pieces is provided with two mounting holes in the length direction. A distance between the two mounting holes is equal to half the length of the mounting piece. The mounting holes on the two mounting pieces are arranged opposite one another, and two corners on another side of each of the two mounting pieces are rounded corners allowing the push-chain to bend. Two adjacent push-chain links of the plurality of push-chain links are hinge-connected in a horizontally staggered arrangement by way of a chain pivot and the mounting holes. | 08-15-2013 |
