Filed:

Oct 7, 2008

Appl. No.:

12/246581

Inventors:

Robert E. Isaacs - Chapel Hill NC, US

International Classification:

G06F 19/00
B21D 7/14

US Classification:

700165, 700 98, 623901, 72 3104

Abstract:

A method is provided for determining the shape of a surgical linking device that is to be attached to a bony body structure such as the spinal column based on digitized locations of a plurality of attachment means engaged to the bony structure. The method is implemented by a computer system through a GUI to generate an initial bend curve to mate with the plurality of attachment means. The initial bend curve may be simplified based on user input to the GUI to reduce the number of bends necessary to produce a well-fitting linking device and may be altered to help obtain the goals of the surgery.

International Classification:

F16H 57/02

US Classification:

74665GA, 74665 R, 74665 N

Abstract:

An output transfer group, or drop box, can include a housing and a gear transfer train, rotatably supported within the housing, that includes an input gear adapted for enmeshing engagement with a transmission output shaft and a gear transfer output shaft that is rotatable upon rotation of the input gear. A coupler can be provided that includes a hub rotatively coupled with the gear transfer output shaft, a bearing carrier, a coupler output shaft rotatively coupled to the bearing carrier, and a coupling mechanism rotatively coupled to the bearing carrier. The coupling mechanism can be movable between an engaged position, wherein the coupling mechanism is rotatively coupled to the hub, and a disengaged position, wherein the coupling mechanism is disengaged from the hub. A solenoid can be arranged with the coupling mechanism to selectively move the coupling mechanism from the disengaged position to the engaged position.

Appl. No.:

13/253838

Inventors:

Robert E. Isaacs - Chapel Hill NC, US

International Classification:

G06K 9/00
A61B 5/05

US Classification:

382131, 382285, 600424

Abstract:

A system and method for displaying images of internal anatomy includes an image processing device configured to provide high resolution images of the surgical field from low resolution scans during the procedure. The image processing device digitally manipulates a previously-obtained high resolution baseline image to produce many representative images based on permutations of movement of the baseline image. During the procedure a representative image is selected having an acceptable degree of correlation to the new low resolution image. The selected representative image and the new image are merged to provide a higher resolution image of the surgical field. The image processing device is also configured to provide interactive movement of the displayed image based on movement of the imaging device, and to permit placement of annotations on the displayed image to facilitate communication between the radiology technician and the surgeon.

International Classification:

A61B 19/00
A61B 17/58

US Classification:

606130, 606102

Abstract:

The present invention relates to a method of determining the proper shape of a surgical linking device that is to be attached to a bony body structure such as the spinal column. The present invention also relates to methods of shaping and bending surgical linking devices such that they fit attachment means or are shaped to fit the bony body structure.

International Classification:

G06F 17/40
G06F 15/00

US Classification:

702182, 702187

Abstract:

A data logging system includes a sensor for monitoring a parameter and a data logger. The data logger includes a first logging mode and a second logging mode. The first logging mode has a low-capacity logging mode adapted to collect data from the sensor at time intervals, identify a start of a data cycle when the parameter reaches a first limit, identify a stop of the data cycle when the parameter reaches a second limit, process the data collected between the start and stop of the data cycle, log the data processed, the data processed having less bytes than the data collected between the start and stop of the data cycle. The second logging mode is adapted to collect data from the sensor at time intervals and to log a portion of the data collected after receiving an event code.

US Classification:

477 2, 74665 A, 475 1

Abstract:

A hybrid drivetrain for a motor vehicle includes an automated mechanical transmission (AMT) having an output shaft. The drivetrain includes an alternative energy source including a motor and an energy storage unit and two torque transfer arrangements. The first transfer arrangement is separate from engageable gear sets of the AMT for transferring torque from the output shaft to a motor when the energy storage unit is being charged and for transferring torque from the motor to the output shaft when the energy storage unit is being discharged. Additionally, an alternative energy source clutch for selectively coupling the first torque transfer arrangement to the output shaft is included. The second torque transfer arrangement is for transferring torque from the output shaft to a driven axle of the motor vehicle. At least one of the first and second torque transfer arrangements has different first and second torque transfer ratios.
