Patent number: 11947388Abstract: A wearable device includes a body having fasteners and a frame coupled between two fasteners. The frame includes first and second sections. A first portion of the body includes the first section of the frame and one fastener and a second portion of the body includes the second section of the frame and the other fastener. A speaker and a microphone are connected to the first portion and another speaker and another microphone are connected to the second portion. The body also includes a processor, memory accessible to the processor, and programming in the memory for configuring the processor to selectively activate the speakers and microphones such that a first speaker emits an output sound signal while a first microphone and a second speaker are deactivated and a second microphone captures an input sound signal during the emission of the output sound signal by the first speaker.Type: GrantFiled: March 7, 2023Date of Patent: April 2, 2024Assignee: SNAP INC.Inventors: Russell Douglas Patton, Jonathan M. Rodriguez, II, Julio Cesar CastaƱeda, Samuel Bryson Thompson

Patent number: 11352584Abstract: A lubricating composition comprises an oil of lubricating viscosity, a metal-free pre-ceramic polymer and one or more co-additives. The metal-free pre-ceramic polymer comprises a plurality of repeat units which do not contain oxygen. The pre-ceramic polymers provide the lubricating oil composition with antiwear properties. Also described is a method of lubricating an internal combustion engine and the use of a lubricating oil composition containing a pre-ceramic polymers to inhibit wear in an internal combustion engine.Type: GrantFiled: February 21, 2018Date of Patent: June 7, 2022Assignee: Infineum International LimitedInventors: Nigel A.

Patent number: 9074037Abstract: An iron-containing polymer is provided for use as a fuel additive for promoting trap regeneration. The polymer shows a beneficial balance of physical properties, and is prepared from iron salts by a polymerization process involving base addition, and subsequent co-ordination of branched-chain polycarboxylate ligands. The polymer can be stored in highly concentrate form, and shows particular suitability for on board dosing systems.Type: GrantFiled: March 7, 2008Date of Patent: July 7, 2015Assignee: Infineum International LimitedInventors: Colin Morton, Russell M. Thompson

Patent number: 8641791Abstract: The invention concerns a method for supplying iron, via the fuel, to the particulate trap of a diesel engine exhaust in a form suitable for promoting trap regeneration. The method involves the addition to the fuel of a defined colloid of iron oxide. Combustion of this colloid produces iron-containing compounds, especially iron oxides, which collect in association with carbonaceous particulate matter in the particulate trap, and function to promote the combustion of this matter. The colloid in particular shows a lower level of associated deposit formation on the fuel injectors than the iron additives of the prior art. The method is thus particularly suitable for modern engines showing increased susceptibility to fuel injector deposits. The colloid also shows a balance of properties providing excellent suitability for use as an additive in fuels, and especially in diesel engine on-board dosing devices.Type: GrantFiled: March 7, 2008Date of Patent: February 4, 2014Assignee: Infineum International LimitedInventor: Russell M. Thompson

Patent number: 8147568Abstract: A diesel fuel composition containing metallic additives that are stabilized against phase separation. The diesel fuel contains a colloidally dispersed or solubilized metal catalyst compound, which can be used for diesel particulate trap regeneration and, as a stabilizer, 5-1,000 ppm (weight) of an oil-soluble or oil-dispersible organic compound having a lipophilic hydrocarbyl chain having attached directly thereto at least two contiguous polar head functional groups, i.e., the functional groups are separated by no more than three carbon atoms. The diesel fuel composition is particularly suitable for use with diesel engines fitted with a particulate trap for emissions control.Type: GrantFiled: September 1, 2004Date of Patent: April 3, 2012Assignee: Infineum International LimitedInventors: Rinaldo Caprotti, Russell M. Thompson
