US Patent:

20210161428, Jun 3, 2021
Filed:

Feb 12, 2021
Appl. No.:

17/174922
Inventors:

Nickolas Peter DEMAS - Watertown MA, US
Ian W. HUNTER - Lincoln MA, US
Assignee:

Massachusetts Institute of Technology - Cambridge MA
International Classification:

A61B 5/091
G10L 25/66
A61B 7/00
A61B 5/083
A61B 5/087
A01K 29/00
G01N 33/497
Abstract:

An acoustic system can track gas emissions by exploiting the nostril-accessible nasal pathways of an animal. Actuators and microphones used in the apparatus can be similar to those currently found in cell phones, which in turn make the acoustic apparatus small and rugged. The nostril geometry can be mapped using sound waves, similar to the mapping done by an acoustic rhinometer. Where acoustic rhinometers assume a constant speed of sound to measure changes in geometry, acoustic approaches as disclosed herein can assume constant geometry to measure changes in the speed of sound. Approaches disclosed here are particularly useful with any gas, such as (for example) methane, hydrogen, helium, etc. that has a speed of sound higher than other typical gaseous components of exhaled air, such as nitrogen, carbon-dioxide, oxygen, etc.

US Patent:

20190094098, Mar 28, 2019
Filed:

Sep 26, 2018
Appl. No.:

16/142385
Inventors:

Nickolas Peter Demas - Cambridge MA, US
International Classification:

G01M 3/18
Abstract:

A device for the measurement of electrical properties on a surface. Sensor consists of several conductive elements arranged at vertices of a three-dimensional geometry. As such, the device achieves a favorable sensing configuration regardless of initial orientation. The device includes circuitry for interfacing with the conductive elements. This circuitry determines the electrical properties of the surface. The measurement has many uses, one of which is to discriminate between dry and wet surfaces. This patent presents various analysis methods to determine the electrical property.

US Patent:

20170197032, Jul 13, 2017
Filed:

Jan 12, 2016
Appl. No.:

14/993345
Inventors:

Nickolas Peter Demas - Cambridge MA, US
Ian W. Hunter - Lincoln MA, US
Michael Thomas Nawrot - Somerville MA, US
Brian Hemond - Cambridge MA, US
International Classification:

A61M 5/30
G01L 5/00
G01L 5/16
Abstract:

A device for the measurement of forces on the tip of a jet injector drug ampoule. Sensor consists of multiple spokes with strain sensing capability where each spoke has formations to allow for quasi-free bending behavior on one spoke end. By using the strain output of all three full bridges in parallel, it is possible to discriminate between lateral forces and axial forces directed collinear with the center axis of the ampoule applied to the tip of the nozzle. This information can be relayed to the user to attain, for example, a pre-determined contact force between the nozzle and an area receiving an injection.
