Publication number: 20220358802Abstract: Embodiments relate to enhanced auditing features for administration of remote electronic keys. An electronic key delivers electrical power to an electronic lock to energize circuitry thereof. The electrical power may energize an electric motor or solenoid. Based on access control information associated with the electronic key, an unlocking signal is conveyed from the electronic key that causes the electronic lock to change from a locked state to an unlocked state, thereby permitting a user of the key to access one or more resources secured by the lock. The electronic key stores details related to the unlocking event in memory sites. In some aspects, the electronic key broadcasts a message via a wireless wide area network (WWAN). The message may include a request to establish a WWAN communications link with an access control server located away from the electronic key.Type: ApplicationFiled: July 14, 2022Publication date: November 10, 2022Inventor: Paul R.

Publication number: 20200340741Abstract: Implementations described and claimed herein provide systems and methods for processing liquefied natural gas (LNG). In one implementation, a solvent is injected into a feed of natural gas at a solvent injection point. A mixed feed is produced from a dispersal of the solvent into the feed of natural gas. The mixed feed contains heavy components. A chilled feed is produced by chilling the mixed feed. The chilled feed includes a vapor and a condensed liquid. The condensed liquid contains a fouling portion of the heavy components condensed by the solvent during chilling. The liquid containing the fouling portion of the heavy components is separated from the vapor. The vapor is directed into a feed chiller heat exchanger following separation of the liquid containing the fouling portion of the heavy components from the vapor, such that the vapor being directed into feed chiller heat exchanger is free of freezing components.Type: ApplicationFiled: April 29, 2020Publication date: October 29, 2020Inventors: Michael J.
