Title: Opposable-element chromatographic assay device
Inventor: CHANDLER HOWARD M
IPC: G01N33/543
Filed: 1994-03-31
Granted: 1997-05-29
Abstract: A chromatographic assay device for use with immunoassays allows rapid and convenient assays of analytes of biological interest, and permits extractions to be carried out in situ, avoiding the use of separate extraction vessels. The device has a wide dynamic range and avoids interference from particulates or colored components. In one form, the device comprises: (1) a first opposable component comprising a sample preparation zone adapted to receive a sample to be assayed; and (2) a second opposable component comprising a chromatographic medium. The first and second opposable components can be brought into opposition so as to cause the sample preparation zone to apply the sample to be tested to the chromatographic medium. Preferably, the analyte is detected with a visually detectable label. Other variations of the device vary the arrangement of components to provide optimal chromatography for a variety of analytes, as well as to permit bidirectional chromatography; still other variations are suitable for competitive immunoassays. The devices can be incorporated in test kits, and assay methods, both sandwich and competitive, using the devices are also disclosed.

Title: Enhanced transdermal transport using ultrasound
Inventor: MITRAGOTRI SAMIR S
IPC: A61M37/00
Filed: 1996-07-25
Granted: 2000-10-12
Abstract: Several means for enhancing transdermal transport of drugs and analytes have been developed, including the use of low frequence ultrasound, chemical modifiers of permeability and/or cavitation, iontophoresis and/or electroporation (electric fields), pressure and/or vacuum (physical enhancers), and magnetic force fields. Applications of low-frequency (approximately 20 KHz to 1 MHz) ultrasound enhances transdermal transport of drugs and measurements of the concentration of analytes in body fluids such as blood or lymph. Delivery can be further enhanced or controlled through the use of carriers for the drugs, such as liposomes or microparticles, using a wide range of ultrasound frequency ranges and intensities. The microparticles are preferably small, and may have surfaces with increased hydrophilicity or lipophilicity to further enhance transport.

Filed: 1980-03-07
Abstract: A device working in conjunction with commercial-grade radar equipment for accurately pinpointing the location of a target or a topological feature with a precision greatly superior to the specified resolution of the radar equipment. This high precision is obtained through on-line treatment of the radar echo signals as the radar scans the target area. In the preferred embodiment of the invention, the device is used for assisting a pilot in steering a ship navigating through coastal or inland waterways. The device provides statistically weighted data relative to the location of a plurality of landmarks in the vicinity of the ship to a KALMAN filter-type circuit which in turn generates an accurate state vector reflecting the ship's present and near future movement. In the course of an initial surveying pass through the waterway, the device can also generate reference charts of the area to be traveled. The device can also be applied to other types of surveying tasks, to the implementation of anti-collision apparatuses, and to other systems requiring a high degree of precision in the measurement of surrounding objects.
