Filed:

Dec 15, 2005

Appl. No.:

11/305263

Inventors:

Hugh Fader - Royal Oak MI, US
Christopher Warren - Farmington Hills MI, US

Assignee:

Ford Global Technologies, LLC - Dearborn MI

International Classification:

F02M 7/28

US Classification:

123435, 123295

Abstract:

An internal combustion engine having a plurality of combustion cylinders configured to operate in a compression ignition mode. A pressure sensor is provided to sense pressure within a combustion cylinder of the engine. A combustion control system, including an electronic engine controller, is configured to receive electrical signals from the pressure sensor and, based on such signals, determine a maximum rate of pressure increase occurring in the combustion cylinder during a first time interval. Based on the determined maximum rate of pressure increase, the combustion control system is configured to control one or more charge inputs to the combustion cylinder during a second time interval.

US Classification:

623 1716

Abstract:

An intervertebral implant and related methods of use are provided for treatment of spaces between two vertebrae. The implant can comprise a first member and a second member that are configured for engagement in a stacked configuration. The first member and second member can be inserted separately so that the intervertebral space can be reached through limited access pathways. The first member and second member can be coupled in situ in the intervertebral space to form an implant of desired height. In this manner, an intervertebral implant having final dimensions that would not fit through a limited access pathway can be implanted through the access pathway by inserting the implant in separate member pieces.

Appl. No.:

9/018364

Inventors:

Ronald Lee Martelli - Ann Arbor MI
Christopher Warren - Farmington Hills MI
William Francis Stockhausen - Northville MI

Assignee:

Ford Global Technologies, Inc. - Dearborn MI

International Classification:

F02B 1700

US Classification:

123295

Abstract:

A variable valve controlled engine causes the inducted exhaust residual to flow from the exhaust port(s) into specific regions of the combustion chamber and remain substantially separate from the air-fuel mixture, thereby creating stratification. The exhaust gas remains substantially on the piston surface and along the entire cylinder wall for at least a portion of the cylinder, with the air-fuel mixture occupying the remaining portion of the chamber.

Abstract:

Tissue dilation systems are disclosed. The present systems provide percutaneous access to one or more target structures located in a patient's body. The tissue dilation systems include two or more tissue dilation tubes telescopically arranged and moveable relative to each other. The tissue dilation tubes can be preassembled prior to use by utilizing a dilation tube retention assembly which can maintain the dilation tubes in a substantially fixed position and release the tubes therefrom in order to dilate a patient's tissue. Methods of producing the present systems and using the present systems in surgical procedures are also disclosed.
