Filed:

Oct 1, 2001

Appl. No.:

09/966102

Inventors:

Boris A. Maslov - Reston VA

Jing Lu - Herndon VA

Assignee:

Wavecrest Laboratories, LLC - Dulles VA

International Classification:

H02K 1100

US Classification:

310 67R, 310216, 310218, 310259

Abstract:

A rotary electric motor is formed within a cylindrical rotor housing structure that surrounds an annular stator ring. The permanent magnet rotor is configured in an annular ring coaxial with, and outside of, the stator. The stator ring contains a plurality of wound core segments that are ferromagnetically isolated from each other. The core segments are secured to a rigid skeletal structure that is centrally fixed to a stationary shaft. The stator support structure is formed of spine members that extend radially away from the center. U-shaped plates at the outer ends of the spine members engage adjacent pair of stator segments. Within the inner periphery of the stator ring, space is provided within which motor control circuitry and battery power supply may be incorporated.

International Classification:

US Classification:

435 6, 435 911, 435 912, 435 9152, 204450

Abstract:

The present invention is a method for detecting DNA sequence differences including single nucleotide mutations or polymorphisms, one or more nucleotide insertions, and one or more nucleotide deletions. Labeled heteroduplex PCR fragments containing base mismatches are prepared. Endonuclease cleaves the heteroduplex PCR fragments both at the position containing the variation (one or more mismatched bases) and to a lesser extent, at non-variant (perfectly matched) positions. Ligation of the cleavage products with a DNA ligase corrects non-variant cleavages and thus substantially reduces background. This is then followed by a detection step in which the reaction products are detected, and the position of the sequence variations are determined.
