Appl. No.:

12/462634

Inventors:

Christopher Bowman - Broomfield CO, US
Duane DeSieno - LaJolla CA, US

Assignee:

Data Fusion & Neural Networks, LLC - Broomfield CO

International Classification:

G06E 1/00
G06E 3/00
G06F 15/18
G06G 7/00
G06N 3/04

US Classification:

706 27, 706 20, 706 26

Abstract:

The present invention extends to methods, systems, and computer program products for detecting, classifying, and tracking abnormal data in a data stream. Embodiments include an integrated set of algorithms that enable an analyst to detect, characterize, and track abnormalities in real-time data streams based upon historical data labeled as predominantly normal or abnormal. Embodiments of the invention can detect, identify relevant historical contextual similarity, and fuse unexpected and unknown abnormal signatures with other possibly related sensor and source information. The number, size, and connections of the neural networks all automatically adapted to the data. Further, adaption appropriately and automatically integrates unknown and known abnormal signature training within one neural network architecture solution automatically. Algorithms and neural networks architecture are data driven, resulting more affordable processing. Expert knowledge can be incorporated to enhance the process, but sufficient performance is achievable without any system domain or neural networks expertise.

Abstract:

The present invention provides polymerizable dental compositions comprising a dimer acid-derived monomer such as a dimer acid-derived di(meth)acrylate monomer. In one embodiment, the dimer acid-derived monomer is of the formula (I): wherein R, R, R, R, Rand Rare independently selected from H and optionally substituted C-Cstraight-chained or branched aliphatic, optionally containing 1 or more double or triple bonds, wherein one or more carbons are optionally replaced by R* wherein R* is —C(O)—, —C(O)C(O)—, —C(O)NR—, —C(O)NRNR—, —C(O)O—, —OC(O)—, —NRCO—, —O—, —NRC(O)NR—, —OC(O)NR—, —NRNR—, —NRC(O)—, —NRC(O)O—, —S—, —SO—, —SO—, —NR—, —SONR— or —NRSO—, where Rand Rare independently selected from H and optionally substituted aliphatic, cycloalkyl, heterocycloalkyl, aryl or heteroaryl; provided that at least two of R, R, R, R, Rand Rare substituted Cstraight-chained or branched aliphatic wherein at least one carbon is replaced by R* and at least one of the substituents is an alkenyl group.

Abstract:

Provided herein are systems and methods for polymerizing and programming a liquid crystal polymer, including a liquid crystal elastomer (LCE) with two-way shape-memory via a stepped or self-limiting reaction. In the described method, the reaction may be stepped to achieve different aspects of the two-way shape-memory effect in the produced LCE. In one embodiment, the method creates a polydomain LCE body with a completed thiol-acrylate Michael addition reaction polymerization. The method may further crosslink the polydomain LCE body under a stimulus, thereby locking a domain state in a portion of the polymer. A two-way shape-memory effect of the LCE may thereafter be programmed and locked into the LCE the second stage polymerization reaction. The self-limiting reaction allows for unprecedented control over LCE domain states and cross-linking densities, as well as the resultant mechanical and optical properties of the LCE formed.
