Publication number: 20240071593Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.Type: ApplicationFiled: October 24, 2023Publication date: February 29, 2024Inventors: Anna Leigh DAVIS, Scott 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.
