US Patent:

6835201, Dec 28, 2004

Filed:

Mar 15, 2001

Appl. No.:

09/809648

Inventors:

Peter T. OHeeron - Houston TX
Terry L. Bohannon - Houston TX
Patrick T. Davis - Houston TX

Assignee:

NeoSurg Technologies, Inc. - Houston TX

International Classification:

A61B 1732

US Classification:

606184, 606167

Abstract:

A trocar is disclosed which comprises a body assembly and a cannula assembly attached to the body assembly to define a bore therethrough. The disclosed trocar also includes an obturator assembly for sliding engagement in the bore. The obturator assembly comprises a shaft having a longitudinal axis and having a distal end for insertion into a patient. The distal end of the obturator includes a tip which is non-conical and which has upper and lower faces that taper away from the shaft to form a V-shaped distal end of the tip. Wing elements provided between the upper and lower faces proximate the distal end of the tip, and the wing elements are spaced apart approximately 180 degrees from one another. The tip of the obturator may also include dorsal elements on the upper and lower faces.

US Classification:

395326

Abstract:

A method and apparatus for creating a process flow diagram from a process model. Process models include processing nodes and process streams. User defined process models can be stored and retrieved for later use. A processor utilizes the process model to determine coordinates for each node and to determine the routing coordinates for each process stream for display. Icons are substituted for nodes for display on the output device, and lines are substituted for process streams also for display on the output device.

International Classification:

G01F 23/263
G01F 23/00

Abstract:

A liquid level sensing system for a vehicle tank may include a liquid level display including a display panel and a first number of visual indicators carried by the display panel. The system may also include capacitive sensors to be coupled to the vehicle tank to sense a second number of possible liquid levels being greater than the first number of visual indicators. In addition, the system may include a controller configured to drive the visual indicators in a modulation pattern based upon the capacitive sensors to thereby display a sensed liquid level having a resolution corresponding to the second number of possible liquid levels.
