Filed:

Sep 19, 2011

Appl. No.:

13/236575

Inventors:

Benjamin Wu - Yorba Linda CA, US
Stephen R. Peck - West Hills CA, US
Shuwu Wu - Yorba Linda CA, US

International Classification:

G01S 19/41
G01S 19/07
G01S 19/55

US Classification:

34235724, 34235738, 34235744

Abstract:

A differential global positioning system (DGPS) processor can include an almost fixed integer ambiguity (AFIA) module for generating in real-time a multiple dimensional state vector of integer ambiguities and multiple dimensional corrections. The AFIA module can use double difference (DD) measurements for pseudo-range (PR) and carrier phase (CP) pairs generated from at least three global positioning system (GPS) receivers. A DGPS processor can be included in a high data rate real time attitude determination (RTAD) system to achieve high heading accuracy with high integrity.

Abstract:

In various embodiments devices and methods for the detection and/or quantification of clinically relevant pathogens (e.g., bacteria, fungi, viruses, etc.) are provided. In certain embodiments the device comprises a lateral-flow assay that detects the bacterium at a concentration of less than about 6×10cells/mL, less than about 3×10cells/ml, less than about 1×10CFU/mL, or less than about 50 μg/mL. In certain embodiments the device comprises an aqueous two-phase system (ATPS) comprising a mixed phase solution that separates into a first phase solution and a second phase solution; and a lateral-flow assay (LFA). In certain embodiments the device comprises a flow-through system comprising a concentration component comprising an aqueous two-phase system (ATPS) comprising a mixed phase solution that separates into a first phase solution and a second phase solution; and a detection component disposed beneath said concentration component.

International Classification:

G01N 33/558
G01N 33/543

Abstract:

Disclosed herein are devices and methods that use aqueous two phase systems and lateral flow assays to detect target analytes in a sample. These devices and methods may be used to diagnose a disease or condition in a biological sample, such as blood or serum. In addition, these devices and methods may be used to detect allergens in a food samples or contaminants, such as environmental toxins, in water samples. Device and kit components may be conveniently assembled in a portable container and are amenable to actuation in most settings. The devices are simple to use, requiring a non-trained operator to simply add the sample to the device. Conveniently, the time it takes to detect the target analyte is very short. Thus, the devices and methods disclosed herein provide novel and useful means for point-of-care.
