Abstract: At least an output shaft angle associated with an output shaft is initialized to a known value where the output shaft is coupled to a motor shaft via a set of one or more gears. A direction of rotation associated with the motor shaft is determined using a plurality of discrete Hall sensors in the motor and the output shaft angle is updated using an incremental value and the direction of rotation.

Abstract: Battery sub-modules are selecting to electrically connect to a common power bus, including by: determining if a discharge-related fault indication for a given battery sub-module indicates that the given battery sub-module is in a discharge-related fault condition. If so, the given battery sub-module is excluded from the selected battery sub-modules such that said given battery sub-module is electrically disconnected from the common power bus. The selected battery sub-modules are configured so that the selected battery sub-modules are electrically connected to the common power bus; the selected battery sub-modules that are electrically connected to the common power bus are charged.

Abstract: A protocol compiler to generate flight code and routing tables is disclosed. In various embodiments, one or more definition files are received. The one or more definition files are parsed to extract flight control system definition data. A communication topology comprising a set of entities of the flight control system and communication links between said entities is determined based on the flight control system definition data. A set of one or more routing tables is generated programmatically based at least in part on the communication topology and message type definition data. Flight code to implement a flight control system defined at least in part by said flight control system definition data is generating programmatically, based at least in part on the flight control system definition data, including code to route messages according to said one or more routing tables.

Abstract: A first measurement of a magnet that rotates is received from a first set of Hall sensors in a first component. A second measurement is received from a second set of Hall sensors in a second component where the first component and the second component are in a plane that is parallel to an axis of rotation associated with the magnet. An angle associated with the magnet is determined based at least in part on the first measurement and the second measurement.

Abstract: A first instruction directed to a first device is received from a controller and via a communication channel with redundancy. The first instruction is sent to the first device via a first communication protocol associated with the first device. A second instruction directed to a second device is received from the controller and via the communication channel with redundancy. The second instruction is sent to the second device via a second communication protocol associated with the second device.
