Abstract: The present disclosure is directed to irradiance sensing devices and methods. One such device includes a housing and an optical diffuser coupled to the housing. The housing has an opening that extends into the housing from an outer surface, and the opening has a circular shape at the outer surface of the housing. The optical diffuser has a first region that extends at least partially beyond the outer surface of the housing and a second region housed within the housing. The first region of the optical diffuser has a curved surface, and the optical diffuser includes a cavity extending at least partially into the second region.

Abstract: A motor assembly that includes a motor (102) having a rotatable shaft, a hub coupled to the rotatable shaft, the hub having a propeller indexer to receive a propeller (104), when the propeller is present, a sensor trigger rotatable with the shaft (100) and positioned at a propeller offset angle ?PROP from the propeller indexer, and a sensor coupled to the motor and positioned to detect the sensor trigger so that the propeller indexer may be positioned at the propeller offset angle ?PROP from the sensor through rotation of the shaft so that said sensor is proximate to the sensor trigger.
