Jul 2, 2001

Appl. No.:

09/898720

Inventors:

Juan A. Lence Barreiro - Santiago de Compostela, ES
Jun Liu - Hartford CT

Assignee:

Otis Elevator Company - Farmington CT

International Classification:

B66B 300

US Classification:

187391, 187247, 187316

Abstract:

Signal processing and diagnostic routines ( ) of elevator controllers ( ) count the total number of runs to landings (O-F) of elevators ( ) along with the number of runs to landings at which a value of a parameter of an elevator door condition or event is notable, (e. g. , too high or too low). If any particular parameter is notable at more than one landing, and the ratio of (a) number of runs to landing at which said particular parameter is notable to (b) the total number of runs to landings exceeds a predetermined threshold, the problem is registered as a car door problem; otherwise, the problem is registered as a landing door problem at each landing where the value of the particular parameter is notable.

Assignee:

Massachusetts Institute of Technology - Cambridge MA

International Classification:

A61K 3816

US Classification:

530352, 530350

Abstract:

The present invention provides novel immunosuppressive agents. In particular, the invention provides immunosuppressive agents that bind calcineurin and/or that inhibit interaction between calcineurin and NF-AT. The invention also provides analogs of these agents, nucleic acids encoding the agents and/or their analogs, gene therapy vectors, etc. , and methods of making and using them.

International Classification:

G06F019/00

US Classification:

702 20

Abstract:

Haplotypes for phased genotypic information are determined from unphased genotypic information. One exemplary method includes separating a dataset that includes genotypic information for a plurality of markers for each of a plurality of individuals into subdatasets, each subdataset including the genotypic information for a subset of the plurality of markers; for each subdataset, identifying haplotypes compatible with marker information for each marker of the subset and for each individual of the plurality; and for each individual, assembling the haplotypes from each of the subsets to provide the individual's haplotype with respect to the plurality of markers.

Appl. No.:

11/977461

Inventors:

Jun Liu - Hartford CT, US
Paul J. Vasques - Middletown CT, US

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

G01M 15/09

US Classification:

702 55, 702 47, 702 50, 73291

Abstract:

A system and method for accurately calculating the oil quantity and oil consumption rate of an aircraft engine detects the level of oil in an oil tank, calculates the oil quantity in the oil tank by compensating for the acceleration of the aircraft, as well as changes in the pitch, yaw and roll of the aircraft. The oil consumption rate of the aircraft is also calculated by calculating the oil quantity at different times, and dividing the difference in oil quantity by the difference in times. The percentage change in oil consumption of the aircraft engine is also calculated. The oil quantity and oil consumption rate can be reported during and after the aircraft's flight.

International Classification:

G06F 15/00
G06F 19/00

US Classification:

702183, 701100

Abstract:

An example data assessment method for a diagnostic system includes receiving a set of initialization data, analyzing the set of initialization data to identify a data outlier in the set of initialization data, and determining whether the set of initialization data is bimodal. The method further includes establishing a set of cleaned data based on the analysis and establishing a baseline operating condition for the device using the set of cleaned data.

International Classification:

C11D 3/04
B65D 69/00

US Classification:

510175, 206223

Abstract:

A cleaning composition and process for cleaning post-chemical mechanical polishing (CMP) residue and contaminants from a microelectronic device having said residue and contaminants thereon. The cleaning compositions are substantially devoid of amine and ammonium-containing compounds, e.g., quaternary ammonium bases. The composition achieves highly efficacious cleaning of the post-CMP residue and contaminant material from the surface of the microelectronic device without compromising the low-k dielectric material or the copper interconnect material.
