Abstract: An electronic device may include a flexible display having first and second display portions that rotate relative to one another about a bend axis. The flexible display may be mounted to a foldable housing having first and second housing portions coupled by a hinge that is aligned with the bend axis. The foldable housing is operable in a flat state and a folded state. A translation assembly may be configured to slide the display relative to the housing as the device moves between flat and folded states. A compression assembly may be used to apply compression to the flexible display when the foldable housing is in the folded state. A tension assembly may be used to apply tension to the flexible display when the foldable housing is in the flat state. If desired, the translation, compression, and tension assemblies may be combined into a module.

Abstract: An electronic device may be provided with peripheral conductive housing structures and a rear wall. An antenna may be formed from a segment of the peripheral conductive housing structures that is separated from the rear wall by a slot. One or more distributed capacitors may be used to tune the response of the antenna. The distributed capacitors may be formed between the segment and a parasitic arm shorted to the rear wall, between a protrusion on the segment and the rear wall, and/or a between conductive traces on a flex coupled to a feed of the antenna. The parasitic arm may be formed from conductive traces on a flexible printed circuit, sheet metal, or other conductive material. The protrusion may extend into the slot and may be embedded in dielectric material. The protrusion may include holes that draw in some of the dielectric material to minimize cosmetic defects.

Abstract: Systems and methods of tracking objects around an ego vehicle, using state estimation of the objects, where state estimation may include an estimate of a position, velocity, acceleration and bounding box size of the tracked object are disclosed. An object may be detected at one or more poses over time. For each pose, a first bounding box may be generated. The largest bounding box may be determined. For each pose, the first bounding box may be expanded to an expanded bounding box. The expanded bounding box may match the largest bounding box. For each pose, the center of the expanded bounding box may be determined. The object may be tracked according to the center of the expanded bounding box.

Abstract: Fusing online and mapped terrain estimates by using weighted grid cells that scales the values returned from online terrain and mapped terrain is disclosed. Previously mapped terrain data and online terrain data are fused and a grid having cells of a predetermined size is overlaid on the terrain map. Each cell may include terrain data based on weighted mapped terrain data and weighted online terrain data, where the weighting values for the mapped terrain data and for the online terrain data may be different. A fused terrain estimate may be a result of a weighted mean for each cell smoothed to reduce noise.
