Apr 25, 2001

Appl. No.:

09/842478

Inventors:

Alan H. Green - Germantown OH
John C. Layman - Trotwood OH
Elaine A. Ruble - Bellbrook OH
Schuyler S. Shaw - Dayton OH

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

B60T 1722

US Classification:

60534, 60545, 92 5 R

Abstract:

A brake master cylinder-sensor system and method are provided. The system includes a master cylinder, a piston slidably positioned in the master cylinder, a magnet positioned on the piston, and a sensor disposed on the master cylinder. A change of piston linear position causes a linear change in a magnetic field position sensed by the sensor, and a brake control signal proportional to the change of piston linear position is generated. A method of operating a brake master cylinder-sensor system includes applying a brake pedal force, changing a piston linear position within a master cylinder, determining a change in a linear magnetic field position proportional to the change of the piston linear position, and generating a brake control signal based on the change in the linear magnetic field position.

International Classification:

B60T011/28

US Classification:

60589, 60562

Abstract:

A vehicle braking system master cylinder that can handle pressure pulses within the brake fluid of a vehicle braking system without the destruction of components internal to a master cylinder. A vehicle braking system master cylinder that allows for component subassembly external to the master cylinder and is self-aligning when assembled. Finally, a vehicle braking system master cylinder that allows for variable travel of the primary piston and the secondary piston within the master cylinder and greater fluid flow in the vehicle braking system.

C08L 23/04

US Classification:

525191, 525240

Abstract:

Disclosed herein is a composition substantially free of polyethylene, wherein the composition includes a thermoplastic material having certain specified mechanical properties, and about 2 wt. % to about 25 wt. % (based on the total weight of the composition) of an olefin mixture that consists essentially of a 30:70 to 70:30 weight ratio of a homogeneous ethylene-alpha olefin interpolymer and a propylene-based elastomer having at least 75 wt. % units derived from propylene and about 10 wt. % to about 25 wt. % units derived from a Cor a Calpha olefin. The specified olefin mixture unexpectedly imparts to the overall composition mechanical properties (such as impact strength, for example) heretofore unattainable. These mechanical properties can be expected to be tailored to suit the end-use expected of the composition.

US Classification:

428332, 264433

Abstract:

The present invention relates to the fields of chemistry and biology and more particularly to the field of biomaterials. The present invention includes amphiphilic fibers and membranes, which can be used for biomembranes and biocompatible devices. The present invention also relates to processes for preparing amphiphilic fibers and membranes from solutions comprising amphiphilic molecules. More particularly, the present invention relates to processes for preparing fibers and membranes from electrospinning solutions comprising amphiphilic molecules. The present invention further provides fibers and nonwoven membranes comprising amphiphilic fibers chosen from anionic surfactants, cationic surfactants, nonionic surfactants, phospholipids, sulfobetaines, lyotropic liquid crystalline molecules, and/or block copolymers. Electrospun fibers offer the potential for direct fabrication of biologically based, high-surface-area membranes without the use of multiple synthetic steps, complicated electrospinning designs, or post-processing surface treatments. Polymeric phospholipids, for example, have been shown to be attractive candidates for blood purification membranes, artificial heart valves and organs, and other prosthetics, including other biocompatible devices.
