Publication number: 20240100296Abstract: A package for a medical device such as an intermittent catheter has a case and a cap connected by threads. The case includes a hollow tube which is closed at one end and open at the other. A shoulder is formed near one end of the case. Above the shoulder is a cylindrical ferrule that includes external threads. The cap has internal threads selectably engageable with the threads on the ferrule to form a liquid-tight seal between the cap and case when the cap is installed on the case.Type: ApplicationFiled: December 5, 2023Publication date: March 28, 2024Inventors: Daniel E.

Patent number: 11577582Abstract: An HVAC air distribution device to promote temperature stratification within a larger volume. The device comprised of a front side coupled to a back side defining a cavity for directing a flow of air. The front side comprised of a pliable material and configured for the distribution of the flow of air within the channel. Accordingly, the front side comprises an air permeable portion to release flow from the channel to provide a low velocity of uniform air flow across a length of the device. This low velocity uniform air flow encourages temperature stratification within a distinct area of the larger volume to increase comfort of an occupant and promote efficiency of HVAC systems.Type: GrantFiled: October 1, 2018Date of Patent: February 14, 2023Inventors: Robert Lattin, Sesha Madireddi, Martin Duffy

Patent number: 11408874Abstract: A system for analysis of at least one analyte gas present in an insulating fluid of an electrical transformer includes a gas sensor in operational contact with at least one analyte gas from an insulating fluid to provide multiple responses from the sensor. One or more processors are configured to receive the multiple responses during exposure of the sensor to the analyte gas from the insulating fluid representative of a concentration of the analyte gas present in the insulating fluid. The processors are configured to select one or more responses of the multiple responses that provide rejection of interfering gases, resolution between gases, improved low detection range of the analyte gas, improved high detection range of the analyte gas, improved response linearity of the analyte gas, improved dynamic range of measurements of the analyte gas, or one or more combinations thereof compared to non-selected responses from the sensor.Type: GrantFiled: June 13, 2017Date of Patent: August 9, 2022Assignee: General Electric Technology GmbHInventors: Radislav Alexandrovich Potyrailo, Chistopher Calvert, Martin Duffy, Craig Mack, Philip McConnell
