Filed:

Jul 14, 2011

Appl. No.:

13/810648

Inventors:

Amit Lal - Ithaca NY, US
Ramkumar Abhishek - Mountain View CA, US

Assignee:

CORNELL UNIVERSITY - Ithaca NY

International Classification:

G01N 11/16

US Classification:

73 5441

Abstract:

An ultrasonic or acoustic viscosity sensor or viscometer is provided that can be used to accurately measure viscosity for fluid samples of less than 1 μl in volume. Methods for measuring viscosity for fluid samples of less than 1 μl in volume are also provided. The viscosity sensor and methods based thereon enable simultaneous measurement of bulk and dynamic (shear-rate dependent) viscosity of a non-Newtonian fluid. Bulk and dynamic viscosity of the non-Newtonian fluid can be measured simultaneously without separating constituents of the fluid, and thus distinguishing the effect of constituents on the viscosity. Dynamic viscosity of the non-Newtonian fluid can be estimated at varying shear rates, to study the deformability of the constituents of the fluid as a function of shear rate.

International Classification:

G06K 7/10

Abstract:

A computer-implemented system and method for entity tracking and identification is provided. A tracker associated with an entity is tracked. Communication is continuously attempted between the tracker and a tracking device associated with an individual in custody of the entity. During one of the attempted communications, an absence of the tracker is determined by identifying a time of the attempted communication and applying a time threshold to the time for the attempted communication. The absence of the tracker is identified when no communication has been established with the tracking device within the time threshold. The entity is classified as missing when the absence of the tracker is determined.

Inventors:

- Menlo Park CA, US
Ramkumar ABHISHEK - Menlo Park CA, US

Assignee:

Abram Scientific, Inc. - Menlo Park CA

International Classification:

G01N 33/86

Abstract:

Disclosed herein are devices for measuring, at one or more time points, one or more properties or changes in properties of a fluid sample. The devices may comprise a chamber defining an internal volume of the device suitable for receiving and retaining the fluid sample; a plurality of layers, the plurality comprising at least a bottom layer below the chamber and at least a substrate layer above the chamber, wherein: the substrate layer is linked to at least one suspended beam at each end of its length; the suspended beam is located above the chamber, the suspended beam having a face capable of physical contact with the fluid sample; and the suspended beam is configured to oscillate upon application of an actuating signal to at least one electrically conductive path, which runs across the suspended beam. Related methods and uses are also disclosed.

Abstract:

A computer-implemented system and method for real-time feedback collection and analysis is provided. A location of a patient associated with an RFID tag is monitored. A space occupied by the patient is determined based on the location and one or more prompts for feedback are identified based on the occupied space. At least one of the prompts is provided to the patient. Feedback is received from the patient in response to the prompt. The received feedback is analyzed.

International Classification:

A61K 9/00
A61M 31/00

Abstract:

Devices and methods are provided for drug delivery. The device may include a housing configured for intralumenal deployment into a human or animal subject and a reservoir contained within the housing and having an actuation end and a release end. The release end may include at least one outlet. A first drug formulation and a second drug formulation may be disposed within the reservoir and adjacent to each other and immiscible, or separated from each other by a first barrier. The device may also include a plug within the reservoir at the actuation end, the plug being movable toward the release end to drive the first and second drug formulations out of the reservoir. The device may also include an actuation system operably connected to the actuation end of the reservoir and configured to drive the plug toward the release end and release the drug formulations from the reservoir.
