    Abstract: For each cell in a plurality of cells, a first cell characteristic and a second cell characteristic are received in order to obtain a plurality of cell characteristics. For each cell in the plurality of cells, a batch compatibility number that is associated with a number of compatible cells that that cell is compatible with is determined based at least in part on the plurality of cell characteristics. The plurality of cells is sorted according to the batch compatibility numbers in order to obtain a sorted list of cells. A list of compatible cells to include in a battery is generated, including by evaluating the plurality of cells according to the order specified by the sorted list of cells and beginning with a cell with the lowest batch compatibility number.

    Abstract: Described embodiments provide a rotor mounting boom assembly for a personal aircraft. The rotor mounting boom assembly includes a rotor mounting boom releasably attachable to a wing of the personal aircraft, one or more vertical lift rotors, and one or more rotor controller assemblies. Controller assemblies for each rotor are positioned on the rotor mounting booms such that downwash from the rotor causes increased airflow across the controller assembly to cool the controller assembly components. A rotor controller enclosure includes an air inlet and an air outlet to allow airflow through the enclosure to cool the controller components. The air inlet is positioned relative to the path of the rotor blades such that the downwash from the rotor that flows into the air inlet is maximized. The structure of the enclosure includes features for increasing the airflow through the enclosure.

    Abstract: Techniques to deploy a parachute are disclosed. In various embodiments, a first projectile is configured to be propelled in a first direction, causing the parachute to be deployed. A second projectile configured to be propelled in a second direction is coupled to a line tethered to the parachute in such a way that a force in a direction opposite the first direction is applied to the line of the parachute when the second projectile is propelled in the second direction.

    Abstract: Thrust values for motors in an aircraft are generated where each flight controller in a plurality of flight controllers generates a thrust value for each motor in a plurality of motors using an optimization problem with a single solution. Each flight controller in the plurality of flight controllers passes one of the generated thrust values to a corresponding motor in the plurality of motors, where other generated thrust values for that flight controller terminate at that flight controller. The plurality of motors perform the passed thrust values.
