Upon locating a collision chain within the hash table, or when probing the collision chain, the bitmask(s) may indicate whether subsequent keys within the collision chain correspond to the given key. The bitmask(s) may represent subsequent keys within the collision chain, and therefore, comparing the given key with the bitmask(s) may indicate similarities therebetween for use in determining whether to search a remainder of the collision chain. |

Growing and splitting a disk array by moving RAID group members
In a storage system that implements RAID (D+P) protection groups a drive subset initially has (D+P) drives with (D+P) partitions. The drive subset is made to be symmetrical such that protection group members are symmetrically distributed in a matrix of drive rows and partition columns that represents the drive subset. A single new drive is added by partitioning the new drive with (D+P) partitions, moving existing protection group members from a selected partition of the (D+P) drives to partitions of the single new drive by rotating the selected partition by 90 degrees, and adding protection group members of a new protection group to the vacated selected partition of the (D+P) drives. The process is repeated until (D+P) new drives have been added in single drive increments. The resulting drive subset is then split by forming a non-symmetric drive subset from the (D+P) drives and forming a symmetric drive subset from the (D+P) new drives. |

Platooning control via accurate synchronization
Various embodiments provide for platooning control via accurate synchronization that will not result in string instability. Some embodiments provide a distributed control scheme for platoon motion control that provides a decentralized implementation of the leader information controller. These control techniques are able to manage the performance of the string of vehicles by maintaining a desired spacing distance between any two successive vehicles in the presence of communications induced delays. In order to regulate the spacing between a vehicle and its predecessor in the string, every vehicle (with the exception of the leader vehicle) uses the relative distance from itself to its predecessor (e.g., as measured using a laser ranging sensor) and a control signal of the predecessor (e.g., received via a wireless link). Various embodiments are capable of dealing with non-homogeneous strings of vehicles and non identical controllers for each vehicle in the string. |

Collision-avoidance system for autonomous-capable vehicles
A collision-avoidance system for use with an autonomous-capable vehicle can continuously receive image frames captured of the roadway to determine drivable space in a forward direction of the vehicle. The system can determine, for each image frame, whether individual regions of the image frame depict drivable space.

Using such techniques, the system can label regions of the image frames as corresponding to drivable space or non-drivable space. By analyzing the labeled image frames, the system can determine whether the vehicle is likely to impact a region of non-drivable space. And, in response to such a determination, the system can generate control signals that override other control systems or human operator input to control the brakes, the steering, or other sub-systems of the vehicle to avoid the collision. |
