Abstract: A method and system utilizes an imaging device that generates images of target tissue of a patient during a surgical procedure that acts on the target tissue imaged by the imaging device. The method and system enables visual detection of patient movement during the surgical procedure by marking at least one spatial attribute of one or more identifiable features of the target tissue illustrated in an image presented in a display window. Prior to acting on the target tissue, a visual indicator of the spatial attribute(s) is superimposed on one or more subsequent images captured by the imaging device and displayed to the operator. The operator can visually compare a position of the visual indicator to a position of the operator-identified feature in order to detect movement of the patient during the procedure. The system and methodology also facilitates realignment that corrects for detected patient movement.

Abstract: The invention is directed to a methodology (and corresponding system) that utilizes an imaging device that generates images of target tissue of a patient during a surgical procedure that acts on the target tissue imaged by the imaging device. The methodology enables an operator to visually detect patient movement during the surgical procedure by initially interacting with the operator to mark at least one spatial attribute of one or more common and easily identifiable features of the target tissue illustrated in an image presented in a display window. Prior to acting on the target tissue, a visual indicator of the operator-inputted spatial attribute(s) is superimposed on one or more subsequent images captured by the imaging device and displayed to the operator. The operator can visually compare position of the visual indicator to position of the operator-identified feature in order to detect movement of the patient during the procedure.

Abstract: This invention is a data editor for modifying recorded driver's log data based on a chosen finite set of events. The data editor includes a data transfer means for loading the recorded driver's log data into the editor. The data editor also has a graphing means for taking the recorded driver's log data and creating a graphic display. Finally, the data editor includes a modifying means for graphically modifying the recorded driver's log data within a predetermined set of rules. This invention is also a novel data editing method. The first step in the method is transferring the recorded driver's log data into a data editor. The next step is graphing the recorded driver's log data on an electronic display. The final step is modifying the recorded driver's log data graphically within preset parameters.

Abstract: A process for the selective hydrogenation and simultaneous isomerization of hydrocarbons in a feed stream (12) containing a mixture of hydrocarbons of varying degrees of unsaturation and having 4 or more carbon atoms. The process comprises contacting the mixture with hydrogen gas under hydrogenating and isomerizing conditions in the presence of a suitable catalyst (2, 3, and 4) in a multistage packed bed catalytic reactor (1). The process comprises supplying the hydrogen gas (20) in increasing molar ratio amounts relative to the remaining unreacted diolefin concentration in at least three points (24, 26 and 28) spaced apart along the flow direction of the feed stream through the reactor.
