Patent number: 11656193Abstract: Aspects of the present application allow for measurement of a calibrated resistance for a resistive film in a sensing element, such that effects from contact resistance and background resistance drifts due to factors such as temperature, strain or aging can be reduced or eliminated. In some embodiments, by taking a plurality of two-terminal resistance measurements between various pairs of electrodes on a resistive film, a contact-resistance-independent resistance of a reference portion of the resistive film can be determined. Further, a contact-resistance-independent resistance of a sensing portion of the resistive film can be determined based on a plurality of two-terminal resistance measurements between pairs of electrodes. The resistance of the reference portion can be removed from the measured resistance of the sensing portion, such that variations in the reference portion resistance that are not caused by a sensed environmental condition may be compensated.Type: GrantFiled: June 11, 2021Date of Patent: May 23, 2023Assignee: Analog Devices, Inc.Inventors: Yosef Stein, Seth S.

Publication number: 20220046336Abstract: Systems and methods are provided for a distributed mufti-sensor witness integrity sensing platform (WISP) approach which allows for positioning of sensors in an enclosed space. In particular, a WISP platform is divided into two modules, with a base module is connected to multiple edge sensor modules with a wired connection. In general, splitting up the distributed WISP system described herein allows multiple sensors to be placed in an enclosed (and generally inaccessible) location. The senor data can be transmitted from the multiple edge sensor modules via a connection to the base module. Additionally, the use of the two module system as provided herein allows the sensors to be positioned meters away from the first module.Type: ApplicationFiled: August 3, 2021Publication date: February 10, 2022Applicant: Analog Devices, Inc.Inventors: Yosef STEIN, Seth S.

Patent number: 10575971Abstract: Hybrid terrain-adaptive lower-extremity apparatus and methods that perform in a variety of different situations by detecting the terrain that is being traversed, and adapting to the detected terrain. In some embodiments, the ability to control the apparatus for each of these situations builds upon five basic capabilities: (1) determining the activity being performed; (2) dynamically controlling the characteristics of the apparatus based on the activity that is being performed; (3) dynamically driving the apparatus based on the activity that is being performed; (4) determining terrain texture irregularities (e.g., how sticky is the terrain, how slippery is the terrain, is the terrain coarse or smooth, does the terrain have any obstructions, such as rocks) and (5) a mechanical design of the apparatus that can respond to the dynamic control and dynamic drive.Type: GrantFiled: July 30, 2018Date of Patent: March 3, 2020Assignee: Bionx Medical Technologies, Inc.Inventors: Hugh M.

Patent number: 10502676Abstract: Corrosion sensors are described. The corrosion sensors may include components formed from carbon nanotube structures and a corroding element formed of a material which corrodes more quickly than a target material being monitored by the corrosion sensor. The corroding material may be exposed to the environment to which the target material being monitored is exposed. The corrosion sensor may be passive, thus consuming little power.Type: GrantFiled: June 30, 2017Date of Patent: December 10, 2019Inventors: Seth S. Kessler, Christopher T. Dunn, Yosef Stein

Patent number: 10411181Abstract: Devices and methods described herein provide electrode pair access from a single side of a device by using one or more via holes through the device. The via hole can pass through or near the center of the device. By creating a conductive path through the via hole of the device, devices and methods of the present disclosure advantageously provide access to a pair of electrodes, each of which contacts a different side of a device layer, on a single side of the device while enabling a greater active device area than is possible using conventional techniques. In addition, the central location of the via hole provides favorable mechanical properties by avoiding radial constriction of the device layers in applications such as piezoelectric devices.Type: GrantFiled: May 30, 2018Date of Patent: September 10, 2019Assignee: Metis Design CorporationInventors: Seth S.
