Patent number: 9389302Abstract: An apparatus and method is provided for real-time location estimation of a mobile station (MS) on a map of roads using non-Global Positioning Satellite location data of the MS and includes a step of determining that the MS is stationary. A next step includes assigning each raw location datum with an initial mass such that the data exhibit an attractive force therebetween. A next step includes calculating a net attractive force for all data using a distance between the data. A next step includes moving each datum a normalized step on the map in response to the net attractive force. A next step includes merging any data that are within a predefined distance on the map and adding their masses. A next step includes repeating the calculating, moving, and merging steps until there are no consecutive merges for a predetermined number of iterations. A next step includes removing any datum with a mass less than a threshold.Type: GrantFiled: June 24, 2013Date of Patent: July 12, 2016Assignee: Google Technology Holdings LLCInventors: Hong-Lei Liu, Kwok Lam Cheung, Sheng-Yu Hu, XiaoHui Shen

Patent number: 8974567Abstract: A gas-liquid rotating coalescer includes first and second sets of one or more detent surfaces on a rotary drive member and a driven annular rotating coalescing filter element which engagingly interact in interlocking mating keyed relation to effect rotation of the coalescing filter element by the rotary drive member. Designated operation of the coalescer requires that the coalescing filter element include the second set of detent surfaces. A coalescing filter element missing the second set of detent surfaces will not effect the noted designated operation.Type: GrantFiled: June 24, 2011Date of Patent: March 10, 2015Assignee: Cummins Filtration IP Inc.Inventors: Barry M. Verdegan, Howard E. Tews, Roger L. Zoch, Bradley A. Smith, Kwok-Lam Ng, Benoit Le Roux, Chirag D. Parikh

Patent number: 8489117Abstract: An apparatus and method is provided for real-time location estimation of a mobile station (MS) on a map of roads using non-Global Positioning Satellite location data (300) of the MS and includes a step of determining (302) a mobility of the MS. A next step (306) includes identifying a region that covers all location data. A next step (310) includes dividing the region into smaller blocks, where each block constitutes a Hidden Markov Model state. A next step (312) includes determining a distance between blocks, to be used in a varied continuous probability distribution to determining a state transition probability of each block to represent a likelihood of the MS moving to any one block. A next step (314) includes using a univariate continuous distribution as a function of a distance between each block and a raw location data.Type: GrantFiled: January 27, 2010Date of Patent: July 16, 2013Assignee: Motorola Mobility LLCInventors: XiaoHui Shen, Hong-Lei Liu, Kwok Lam Cheung, Sheng-Yu Hu

Patent number: 8097061Abstract: A filter assembly is described that includes a unique seal configuration between a filter and a housing. The filter has a filter media that allows fluid to be filtered therethrough, and has an endplate with an opening that allows fluid to flow into or out of the filter media. The endplate has a main surface with an elliptical spud protruding outward from the main surface and surrounding the opening. An oval seal is disposed about an outer surface of the elliptical spud. The housing is releasably connected to the filter, and has a mounting component. The mounting component has an elliptical boss that mates with the elliptical spud and seals against the oval seal.Type: GrantFiled: September 18, 2008Date of Patent: January 17, 2012Assignee: Cummins Filtration IP, Inc.Inventors: Bradley Smith, Kwok-Lam Ng, Benjamin L.
