Appl. No.:

09/285663

Inventors:

Gregory Lynn Jones - Carmel IN
Thomas Alton Peterson - Kokomo IN
Paul D. Koottungal - Indianapolis IN

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

F02P 900

US Classification:

307 106, 123597, 123605

Abstract:

In a vehicle having an engine and an ignition system, a sensing circuit is provided for sensing the ignition voltage and providing this sensed signal to various operating modules of the vehicle. The sensing circuit includes a diode/resistor filter that provides a filtered voltage signal at a first output node. A compensation circuit is provided that compensates voltage errors introduced by the filter circuit. The compensation circuit includes a second diode that has substantially identical electrical performance characteristics as the first diode, and that is preferably mounted on a common substrate. A voltage signal at a second output node between the second diode and the filter circuit is indicative of the voltage drop across the second diode, which is further representative of the voltage error introduced by the filter circuit. In one embodiment, the operating module receiving the ignition voltage signal is configured to receive voltage signals at the first and second output nodes. The operating module can include a microprocessor that receives the A/D converted voltage signals and subtracts the signal at the second output node from the signal produced by the filter circuit according to a predetermined relationship.

International Classification:

C08F 263/00

US Classification:

525244000, 525331900

Abstract:

The present invention is a rheology-modifiable polymeric composition or a free-radical crosslinkable polymeric composition, wherein the resulting rheologymodifying bond or crosslinking bond is a thermally-reversible bond. The resulting polymer is prepared from at least one polymer which upon forming free radicals preferentially degrades or carbon-carbon crosslinks. The present invention permits suppression of the preferential reaction while permitting the polymer to be coupled or crosslinked through a thermally-reversible bond. Suppressing the undesirable degradation or carbon-carbon crosslinking reaction and permitting the desirable reaction yield a rheology-modified polymer or a free-radical thermally-reversibly crosslinked polymer.

International Classification:

C08F 442

US Classification:

526160

Abstract:

The invention relates to a process for the polymerization of olifins in the presence of an activated catalyst composition comprising a single site catalyst precursor and an activating cocatalyst, which comprises contacting outside of a polymerization reactor a single site catalyst precursor with an activating cocatalyst before, during, or after contacting the single site catalyst precursor with a weakly coordinating electron donor that does not substantially polymerize during either contacting.

International Classification:

US Classification:

250367

Abstract:

A modular solid state x-radiation detector. A detector array is made up of a plurality of collimator plates having pockets formed in the planar surfaces thereof to carry scintillator bars, and dimensioned so that the edges of the scintillators are shielded by the pockets, yielding several advantages. Wider scintillator bars are thus possible, increasing quantum detection efficiency while guarding against energy dependent punch through at the edges of the scintillator, thereby to enhance spectral linearity. The arrangement also prevents x-rays from bypassing the scintillator, thus protecting the adhesive which bonds the scintillator to the plate and the photodiodes mounted behind the scintillator. A further benefit is an increase in optical transfer of light to the rear of the scintillator where the diode is mounted since there is a less severe aspect ratio of depth to width, reducing the number of reflections encountered by light travelling to the photodiode. The collimator plates are also provided with opposed legs which engage slots in a photosensor assembly to accurately align the photosensor and scintillator.

Abstract:

An automated bioreactor system for decellularizing an organ includes a main chamber for containing the organ. The system further includes a reagent chamber containing a liquid phase reagent. A reagent conduit delivers the liquid phase reagent to the main chamber, and a perfusion conduit delivers the reagent from the reagent outlet in the main chamber into the organ. A perfusion pump drives the flow of the reagent. A perfusion pressure sensor detects a pressure of the flowing reagent. A control system controls the perfusion pump to drive the flow of the reagent based on a received input representative of a desired pressure and a received input of the detected pressure. The control system may automatically perform all of the steps of a decellularization protocol based on sensor input. An automated waste decontamination system may also be provided.
