Abstract: A default-to-park mechanism for a transmission includes an output member, a rotatable plate, a latching mechanism, and a biasing member. The output member is rotatable to park, reverse, neutral, and drive positions. The rotatable plate is coaxial with the output member. The plate and the output member interfere with one another such that the plate is moved in a first direction of rotation by the output member and the output member is moved in a second direction of rotation by the plate. The plate is releasably held by the latching mechanism to prevent rotation in the second direction of rotation when the output member is in the reverse, neutral, and drive positions. The biasing member biases the plate to rotate in the second direction of rotation to return the output member to the park position when the plate is released by the latching mechanism.

Abstract: A vision system is configured to dynamically inspect an object in a field of view. This includes capturing, using a camera, three-dimensional (3D) point cloud data of the field of view and transforming each of the points of the 3D point cloud data into a plurality of tangential surface vectors. Surface normal vectors are determined for each of the points of the 3D point cloud data based upon the plurality of tangential surface vectors. Distribution peaks in the surface normal vectors are detected employing a unit sphere mesh. Parallel planes are separated using the distance distribution peaks. A radially bounded nearest neighbor strategy combined with a process of nearest neighbor searching based upon cell division is executed to segment a planar patch. A planar surface is identified based upon the segmented planar patch.

Abstract: A system and method of thermal management for an engine are provided. The system includes an engine, an electrical water pump, and a controller. The controller has a processor and tangible, non-transitory memory on which is recorded instructions. Executing the recorded instructions causes the processor to continuously monitor the temperature of the cylinder head and the temperature of the coolant. If the monitored temperatures of the cylinder head and the coolant are below predetermined thresholds, the processor executes a first control action, in which the pump remains off and the coolant remains stagnant. If either of the monitored temperatures of the cylinder head or coolant reaches the respective predetermined threshold, the controller initiates a second control action, which requires the controller to signal the pump to turn on and circulate coolant. The controller then determines the desired operating speed of the electrical water pump based on engine load.

Abstract: A machine vision system including a digital camera can be employed to inspect an object in a field of view. This includes projecting digitally-generated light patterns including first and second boundary patterns and first and second spatial patterns onto the object in the field of view. Images associated with the projected light patterns including the object are captured.

The spatial cells are found in the field of view by matching codes in the spatial patterns to boundaries determined based upon the boundary patterns. The spatial cells are decoded and matched to the boundaries. Three-dimensional (3D) point cloud data of the object is generated based upon the decoded spatial cells matched to the boundaries.
