Abstract: An autonomous vehicle (AV) is described herein. The AV is configured to identify an occluded region where a portion of a field of view of a sensor is occluded by an object. The AV is further configured to hypothesize that an object exists in the occluded region and is moving in the occluded region. The AV is still further configured to perform a driving maneuver based upon the hypothesized object existing in the occluded region.

Abstract: A system for fabricating a double-contoured shim includes a model generator and a manufacturing system. The model generator generates a shim model to fill a gap between a first mating-surface and a second mating-surface. The model generator generates a virtual plane that divides the shim model into a first shim model and a second shim model. A first shim is fabricated based on the first shim model. The first shim includes a first contoured shim-surface that is complementary to a first mating-surface area of the first mating-surface and a first planar shim-surface that is opposite the first contoured shim-surface. A second shim is fabricated based on the second shim model. The second shim includes a second contoured shim-surface that is complementary to a second mating-surface area of the second mating-surface and a second planar shim-surface that is opposite the second contoured shim-surface.

Abstract: A manufacturing system includes a holding structure and actuators that are coupled to the holding structure. The actuators support the component and apply displacements to select locations of the component to change a current shape of the component toward a target shape of the component. The system includes a metrology system that takes measurements of the current shape of the component. The system includes a controller that utilizes a closed feedback loop to determine a deviation between the current shape and the target shape based on the measurements and to provide commands that iteratively change the displacements in response to changes in the current shape until the current shape is within a tolerance of the target shape.

Abstract: A smart power center is for use in controlling DC power in mobile living quarters, such as an RV, and has switched outputs that are controlled using a mobile device, such as smartphone or tablet. The switched outputs connect DC power from a DC power source to an accessory, such as a light, fan, or motor. Some accessories, such as landing gear or slide-out rooms, require the polarity from the power source to be reversed for proper function. These are connected to reversing outputs which connect DC power from the DC power source in one orientation for one direction and a reversed orientation for the other direction. Smart override switches can be wired to the smart power center in the event the user desires to control the switched outputs without the mobile device.

The control circuit selectively outputs one or more enable and/or inhibit signals based on the states of the motion sensor and timer. The time delay override switch can be actuated to place the timer into a timed out state from a timing state.
