Patent number: 11937082Abstract: A secure electric vehicle (EV) charger and system incorporating thereof is provided. One embodiment includes an EV charger. The EV charger includes a processor, a low power short range point-to-point communication system, and a memory containing an authentication software application. The processor is configured by the authentication software application to receive an authentication request from a mobile device via the low power short range point-to-point communication system, send encrypted EV charger access credentials to the mobile device, receive a digital token from the mobile device, verify the digital token, and initiate a charging session based upon a command contained within the digital token. The digital token may be encrypted using a public key and may be self-authenticating without use of an internet connection thus enabling secure charging without the presence of an internet connection.Type: GrantFiled: December 2, 2020Date of Patent: March 19, 2024Assignee: EVE Energy Ventures Inc.Inventor: Nikhil Srinath Bharadwaj

Patent number: 5301561Abstract: A fluid sampling device particularly suited for downhole applications is disclosed. The device has a tubular housing with a retractable sample tube nested within. The housing and sample tube have generally pointed leading edges to facilitate embedment into the formation to a sufficient depth to isolate the fluid sample to be obtained from well fluids. Having embedded the apparatus a sufficient depth, a downward force is applied to the sample tube, severing its prior restraint to the housing and extending the sample tube into the formation. Openings in the sample tube allow the fluid to come through it, whereupon it is conducted to the surface. Removal of the downward forces applied to the sample tube allows a biasing mechanism to act on the sample tube to retract it into the housing prior to the removal of the housing from the formation.Type: GrantFiled: May 28, 1991Date of Patent: April 12, 1994Assignee: Energy Ventures, Inc.Inventor: Haraldur Karlsson

Patent number: 5253720Abstract: The invention is a coring device which has features to seal off from the well fluids prior to taking of the specimen. The apparatus can be hydraulically or pneumatically actuated to move an inner string which is connected to a core barrel. Prior to moving the core barrel, an outer tube is sealingly pushed into the formation. Once the outer tube has been set into the formation, the inner tube drives the core barrel into the formation, leaving behind a rabbit. A clam shell is located at the forward end which stays open as the core barrel is driven into the formation and closes as the core barrel is withdrawn into the outer tube to retain the core. The pneumatic or hydraulic pressure continues to be applied to the inner string as the core barrel is withdrawn into the outer tube. Upon full retraction of the core barrel into the outer tube, a ball valve is actuated to seal off the core barrel. At that time, the hydraulic or pneumatic pressure is removed and the apparatus is pulled to the surface.Type: GrantFiled: June 13, 1991Date of Patent: October 19, 1993Assignee: Energy Ventures, Inc.Inventors: Steven R. Radford, Haraldur Karlsson, James T. Aumann
