Assignee:

California Institute of Technology - Pasadena CA

International Classification:

G01N 27/00
G01R 33/00

US Classification:

324228

Abstract:

The invention relates to an integrated measurement system to detect a quantity of magnetic particles in a sample. The measurement system includes a substrate. An electromagnetic (EM) structure disposed on the surface of the substrate is configured to receive a sample including the magnetic particles in proximity thereof. The integrated measurement system also includes an electrical current generator disposed on the surface of the substrate which is electro-magnetically coupled to the EM structure. The electrical current generator is configured to cause an electrical current to flow in the EM structure. The integrated measurement system also includes an effective inductance sensor disposed on the surface of the substrate which is configured to measure a selected one of an effective inductance and a change in effective inductance. The invention also relates to a method to determine the number of and/or the locations of the magnetic particles in a sample.

International Classification:

A61C 7/08
A61C 7/36
A61C 7/00

Abstract:

An orthodontic aligner includes a first plastic segment having a first shape that fits over a first portion of a dental arch of a patient, a second plastic segment having a second shape that fits over a second portion of the dental arch of the patient, and a connector that joins the first plastic segment to the second plastic segment. The connector is configured to be disposed along a lingual side of one or more additional teeth of the patient without exerting a clinically significant force on the one or more additional teeth. The connector spans a gap between the first plastic segment and the second plastic segment, the gap corresponding to the one or more additional teeth that are not to receive the clinically significant force. The connector includes a flexible material that will perform at least one of flex, move or change shape responsive to applied forces.

International Classification:

F01D 25/16
F16C 19/52

Abstract:

A bearing assembly monitoring system includes a bearing assembly supporting rotation of a rotating member. The bearing assembly includes a fixed portion and rotatable portion. A piezoelectric element is mounted to the fixed portion and generates an electric signal in response to a vibration of the fixed portion. A first transceiver is electrically coupled to the piezoelectric element to receive the electrical signal generated by the piezoelectric element and generate a signal indicative of the vibration of the fixed portion. A gas turbine engine bearing monitoring system and a method are also disclosed.

International Classification:

A61C 7/08
A61C 7/36
A61C 7/00

Abstract:

A method includes forming a plastic orthodontic aligner having a plurality of cavities shaped to receive at least portions of a plurality of teeth of a patient. A first segment of the plastic orthodontic aligner corresponds to a first subset of the plurality of cavities for moving a first subset of the plurality of teeth of the patient. A second segment of the plastic orthodontic aligner corresponds to a second subset of the plurality of cavities. The method further includes removing a first portion of the plastic orthodontic aligner between the first and second segments of the plastic orthodontic aligner to form a connector to minimize force transmission between the first and second segments. The connector is configured to be disposed along one or more additional teeth to span a gap between the first and second segments without exerting a clinically significant force on the one or more additional teeth.

International Classification:

G06K 9/00

Abstract:

There is provided a method to identify structure of a native PDF document. The method comprises: obtaining a native PDF document having a first line to start a table and a second line to end the table; detecting a value of a physical feature of the native PDF document, wherein the physical feature has a corresponding weighting factor; initiating a value to the weighting factor; assigning a first status for the first line and a second status for the second line based on (a) the physical feature and (b) the weighting factor; and identifying a location of the table on native PDF document from the first status and the second status, thus yielding an identified location of the table.
