Abstract: An O-ring collar seal for an interface between adjacent first and second components includes a cylindrical structure arranged along a longitudinal axis and characterized by an L-shape in a cross-sectional view. The L-shape includes a first section orthogonal to the longitudinal axis, with a distal end extending toward the axis for being sandwiched between the components. The L-shape also includes a second section extending from the first section, arranged parallel to the longitudinal axis, and configured to retain the O-ring collar seal on the first component. The L-shape additionally includes a round shape third section arranged on the first section's distal end for being compressed by the adjacent components to generate sealing pressure therebetween when the O-ring collar seal is installed in the interface. The first and second sections of the L-shape together define a collar portion and the third section defines an O-ring portion of the O-ring collar seal.

Abstract: A communication system for a vehicle includes a controller adapted to selectively execute an alternative periodic connectivity mode for communication between a user of the vehicle and a remote assistance unit. The vehicle is not connected to a wireless plan. The controller has a processor and tangible, non-transitory memory on which instructions are recorded. The alternative periodic connectivity mode is activated based in part on at least one automatic trigger and/or a request from the user. The controller is adapted to assign a distinct identifier to the vehicle during execution of the alternative periodic connectivity mode. The distinct identifier is defined by a plurality of parameters, including a connection time interval, an internet protocol address range and a host port. The internet protocol address range and the host port may be dynamically configured to remain disengaged unless given a system clearance.

Abstract: A method for controlling operation of a motor vehicle includes an electronic controller receiving, e.g., from a vehicle-mounted sensor array, sensor data with dynamics information for a target vehicle and, using the received sensor data, predicting a lane assignment for the target vehicle on a road segment proximate the host vehicle. The electronic controller also receives map data with roadway information for the road segment; the controller fuses the sensor and map data to construct a polynomial overlay for a host lane of the road segment across which travels the host vehicle. A piecewise linearized road map of the host lane is constructed and combined with the predicted lane assignment and polynomial overlay to calculate a lane assignment for the target vehicle. The controller then transmits one or more command signals to a resident vehicle system to execute one or more control operations using the target vehicle's calculated lane assignment.
