Abstract: When locating a semiconductor die on a substrate, the die is picked up and carried with a die-holding surface of a bonding tool having a protrusion. The protrusion of the bonding tool is configured to be movable between a retracted position within the die-holding surface and an extended position protruding from the die-holding surface. When the protrusion is located in the extended position, the die is bent when the bonding tool is carrying the die. Thereafter, the bonding tool is moved to flatten the die against the substrate while the substrate urges the protrusion to retract from the extended position towards the retracted position.

Abstract: Embodiments of the present disclosure relate to behavior planning for autonomous vehicles. The technology described herein selects a preferred trajectory for an autonomous vehicle based on an evaluation of multiple hypothetical trajectories by different components within a planning system. The various components provide an optimization score for each trajectory according to the priorities of the component and scores from multiple components may form a final optimization score. This scoring system allows the competing priorities (e.g., comfort, minimal travel time, fuel economy) of different components to be considered together. In examples, the trajectory with the best combined score may be selected for implementation. As such, an iterative approach that evaluates various factors may be used to identify an optimal or preferred trajectory for an autonomous vehicle when navigating an environment.

Abstract: In various examples, a current claimed set of points representative of a volume in an environment occupied by a vehicle at a time may be determined. A vehicle-occupied trajectory and at least one object-occupied trajectory may be generated at the time. An intersection between the vehicle-occupied trajectory and an object-occupied trajectory may be determined based at least in part on comparing the vehicle-occupied trajectory to the object-occupied trajectory. Based on the intersection, the vehicle may then execute the first safety procedure or an alternative procedure that, when implemented by the vehicle when the object implements the second safety procedure, is determined to have a lesser likelihood of incurring a collision between the vehicle and the object than the first safety procedure.

Abstract: A point to point radio alignment system is disclosed. A voltmeter positioned at the first antenna measures alignment voltage that is generated from an alignment of the first radio component positioned on the first antenna. A transceiver positioned at the first antenna receives a second alignment voltage that is measured at the second antenna and generated from an alignment of the second radio component positioned on the second antenna. A controller positioned at the first antenna simultaneously monitors the first alignment voltage as the alignment of the first radio component is adjusted and the second alignment voltage as the second radio component is adjusted. The controller simultaneously displays the first alignment voltage as the first radio component is adjusted and the second alignment voltage as the second radio component is adjusted to enable a first user to track an alignment of the first radio component and the second radio component.
