Publication number: 20190153740Abstract: A passive damper with a cylinder and piston arrangement, the cylinder being arranged to be connected to a first item, the cylinder having a first chamber and a second chamber. The piston arrangement is connected to a second item, the piston arrangement comprising a piston movable in the cylinder. A fluid passage is associated with a one-way valve. Damping fluid substantially freely flows through the fluid passage in a first direction of movement of the piston arrangement in the cylinder and the damping fluid is restricted from flowing through the fluid passage in a second direction of movement of the piston arrangement in the cylinder. Damping fluid relatively freely flows around the piston when the piston is in the second chamber of the cylinder and the damping fluid is restricted from flowing around the piston when the piston is in the first chamber of the cylinder.Type: ApplicationFiled: March 31, 2017Publication date: May 23, 2019Inventors: James Geoffrey CHASE, Geoffrey William RODGERS

Patent number: 10244945Abstract: A method for an optical elastography system converts digital images of an actuated breast into a description of surface motion. The surface motion can subsequently be used to ascertain whether the breast has regions of abnormal stiffness, e.g., indicating a significant likelihood of breast cancer. The steps of the method use a model based segmentation to identify profile of the breast in each image, and for each pair of images computing skin surface motion using an optical flow algorithm. This method eliminates a preliminary step of placing fiducial markers on the subject.Type: GrantFiled: August 23, 2018Date of Patent: April 2, 2019Assignee: Tiro Medical LimitedInventors: James Geoffrey Chase, Tom Botterill

Publication number: 20080306353Abstract: A method of providing blood glucose therapy for a critically ill patient includes calculating a baseline nutrition feed requirement based on an algorithm that incorporates at least one of age, gender, and body size of the patient: determining a first blood glucose level; determining a second blood glucose level after a preselected time interval: determining a first body temperature reading: comparing the blood glucose levels: and administering either nutrition or insulin. The amount of nutrition administered to the patient is based on a first change in blood glucose level, the current body temperature reading, and a predetermined feed algorithm based on the second blood glucose level as well as the baseline nutritional feed requirement. The amount of insulin administered is based on a second change in blood glucose level, body temperature, and a predetermined insulin algorithm that incorporates at least one of the patient's body frame size, age, and gender.Type: ApplicationFiled: October 9, 2007Publication date: December 11, 2008Inventors: Joel S.

Publication number: 20020100889Abstract: This invention relates to a method and apparatus for high-speed fluid flow control. More particularly, the invention is directed to a valve formed, at least in part, of an actuating material, such as piezoelectric or anti-ferro-electric material. The valve is used for controlling fluid flow (including air flow) in a variety of devices including imaging devices (e.g. printers, copiers, etc.) for which air flow is used to handle paper. In one embodiment, the subject valve takes advantage of the phenomenon of buckling, resultant bistability and other structural mechanics to efficiently, and in a high-speed manner, open and close to regulate fluid flow. In another embodiment, the valve includes implementation of the actuating material to bend an s-shaped blocking element within the valve. The valve is also advantageously implemented in matrices and formed using batch fabrication techniques.Type: ApplicationFiled: November 24, 1999Publication date: August 1, 2002Inventors: JAMES GEOFFREY CHASE, MARK HOSANG YIM, WARREN BRUCE JACKSON, RACHEL KING-HA LAU, DAVID KALMAN BIEGELSEN
