Title: End effector force sensor and manual actuation assistance
Inventor: BRENT ANDREW BAILEY
IPC: A61B34/30
Filed: 2018-08-28
Abstract: The positioning system 500 includes a multi-joint positioning arm 502, an end effector 504 coupled to a distal end of the positioning arm, a force-moment sensor (FMS) 506 coupled to the end effector and a controller coupled to communicate with the positioning arm and the FMS. Using signals from the FMS, at least one external force or torque applied to the end effector is determined. A drive velocity for moving the end effector is determined, based on the at least one external force or torque. One or more joint movements of the positioning arm for moving the end effector is calculated, according to the drive velocity. The positioning arm is moved according to the one or more calculated joint movements. The end effector may include a handle (512, fig 6). The system may form part of a medical navigation system also having a tracking system for tracking markers attached to the positioning arm and end effector. The end effector may be configured to support an imaging system or a medical instrument.

Inventor: NAVID HAJIMIRZA
IPC: G06F3/01
Filed: 2018-10-03
Abstract: The method comprises the steps of displaying a browser window on a display (210, Fig.2); estimating a user's (220, Fig.2) gaze point within the display (210, Fig.2); transforming the geometry of the estimated gaze point and/or the geometry of the browser window to a common coordinate system; identifying an object (215, Fig.2) in the browser window that corresponds to the estimated gaze point; and storing the estimated gaze point and data corresponding to the identified object (215, Fig.2). The transforming the geometry step may involve estimating X and Y coordinates of the estimated gaze point within an area of the display and transforming the estimated coordinates to corresponding coordinates in an area of the browser window. The browser window may comprise a rendered hypertext markup page (web page, HTML, internet). The method may identify objects from a document object model or DOM, defining the browser window. The data corresponding to an identified DOM object may be collected by accessing source uniform resource identified or URI of the identified object. The method may be used for applications such as extracting percentage norms e.g. the percentage of users who notice an advertisement or for how much attention a given user gives a specific video.
