Patent number: 12125355Abstract: Video monitoring and alarm verification technology, in which a first connection is established between a first device and a camera located in a monitored property associated with a user of the first device and image data captured by the camera is received over the first connection and at the first device. A determination is made to establish a second connection with a second device that enables sharing of the received image data with the second device and, in response to the determination, the second connection is established between the first device and the second device. The received image data is shared with the second device over the second connection and the second device is restricted from directly accessing image data captured by the camera located in the monitored property.Type: GrantFiled: July 11, 2023Date of Patent: October 22, 2024Assignee: Alarm.com IncorporatedInventors: Alison Jane Slavin, Robert J. McCarthy, Jr., David James Hutz, Stephen Scott Trundle, Jean-Paul Martin

Patent number: 11542446Abstract: Methods are provided for using a molecular sieve catalyst for dewaxing formed using a synthesis mixture comprising a morphology modifier. The catalyst may be used, for example, for production of a lubricant base stock. For example, ZSM-48 crystals formed using the morphology modifier (and/or formulated catalysts made using such crystals) can have an increased activity and/or can provide an improved yield during catalytic dewaxing of lubricant base stocks.Type: GrantFiled: August 14, 2019Date of Patent: January 3, 2023Assignee: Exxon Mobil Technology and Engineering CompanyInventors: Preeti Kamakoti, Scott J.

Patent number: 11198115Abstract: Methods are provided for forming noble metal catalysts comprising both platinum and a second Group VIII metal, such as palladium, with improved aromatic saturation activity. Instead of impregnating a catalyst with both platinum and another Group VIII metal at the same time, a sequential impregnation can be used, with the Group VIII metal being impregnated prior to platinum. It has been discovered that by forming a Group VIII metal-impregnated catalyst first, and then impregnating with platinum, the distribution of platinum throughout the catalyst can be improved. The improved distribution of platinum can result in a catalyst with enhanced aromatic saturation activity relative to a catalyst with a similar composition formed by simultaneous impregnation.Type: GrantFiled: December 9, 2019Date of Patent: December 14, 2021Assignee: ExxonMobil Research and Engineering CompanyInventors: Matthew S. Ide, Stephen J. McCarthy, Gary P. Schleicher

Patent number: 10669491Abstract: Methods are provided for making base metal catalysts with improved activity. After forming catalyst particles based on a support comprising a zeolitic molecular sieve, the catalyst particles can be impregnated with a solution comprising a) metal salts (or other precursors) for a plurality of base metals and b) an organic dispersion agent comprising 2 to 10 carbons. The impregnated support particles can be dried to form a base metal catalyst, and then optionally sulfided to form a sulfided base metal catalyst. The resulting (sulfided) base metal catalyst can have improved activity for cloud point reduction and/or for improved activity for heteroatom removal, relative to a base metal dewaxing catalyst prepared without the use of a dispersion agent.Type: GrantFiled: November 30, 2016Date of Patent: June 2, 2020Assignee: ExxonMobil Research and Engineering CompanyInventors: Stephen J.

Patent number: 10240094Abstract: Systems and methods are provided for modifying the composition of the conversion catalyst in a reactor for oxygenate conversion during conversion of an oxygenate feed to allow for adjustment of the slate of conversion products. The modification of the conversion catalyst can be performed by introducing a substantial portion (relative to the amount of catalyst inventory in the reaction system) of make-up catalyst having a distinct composition relative to the conversion catalyst in the reaction system. Introducing the distinct composition of make-up catalyst can modify the composition of the conversion catalyst in the reactor to allow for changes in the resulting product slate. By introducing the distinct catalyst composition, the conversion catalyst in the reactor can correspond to a different composition of catalyst than the overall average catalyst composition within the catalyst inventory in the reaction system.Type: GrantFiled: January 5, 2018Date of Patent: March 26, 2019Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Brandon J.
