  • Patent number: 9389302
    Abstract: 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.

  • Patent number: 8974567
    Abstract: 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.

  • Patent number: 8489117
    Abstract: 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.

  • Patent number: 8097061
    Abstract: 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.
