Abstract: An aircraft uses trajectory-based control algorithms for blade pitch (or twist). This approach greatly enhances the ability of the actuator to accurately achieve the desired blade pitch and to track the commanded pitch position. An actuator includes an electronic rotor blade controller that converts communicated or desired changes in pitch (or similar parameter) to actual physical effects that match the desired changes as closely as possible. The controller preferably includes a motor drive circuit, such as an h-bridge, a communication circuit for connection to external commands, and a processor with associated enabling circuitry (e.g. memory, I/O) to coordinate and implement the control.

Abstract: Various arrangements for wireless network provisioning using a pre-shared key (PSK) are presented. A plurality of wireless network access profiles that indicate a plurality of PSKs may be stored. An access point may receive, from a wireless device, a first value based at on the PSK. The access point can transmit the first value to a cloud-based provisioning system. A plurality of values based on the plurality of PSKs of the plurality of wireless network access profiles may be created and a match between a second value of the plurality of values and the transmitted first value may be identified. A third value may be provided to the access point based on the PSK of the wireless network access profile of the plurality of wireless network access profiles used to generate the value. Network access can then be granted based on the third value.

Abstract: Level-shifting circuits including a plurality of p-type metal oxide semiconductor (PMOS) devices and n-type metal oxide semiconductor (NMOS) devices may be used to level-shift an input voltage signal between a low voltage domain having a low voltage level and a high voltage domain having a high voltage level, to obtain an output voltage signal having an output voltage level at an output node. A current-controlled tie circuit may be connected between the output node and the output voltage level, to conduct a current that causes the output node of the level-shifting circuit to be in a pre-defined logic state during a power-up sequence of the level-shifting circuit. Accordingly, spurious, non-deterministic output levels are avoided during the power-up sequence.
