Disclosed are exemplary remote programming systems, software and methods for use in remotely programming field devices, such as engines, power generators, controllers, and data sensors, and the like. The rotor is rotatable on a shaft supported by bearings, with at least one of the bearings being positioned longitudinally within the stator core. A stream of the RF transceivers are released to form a line of RF transceivers underwater such that the individual RF transceivers have an RF transmission and reception distance greater than the distance between the RF transceivers whereby an RF signal can be repeatedly retransmitted down the line of RF transceivers. Each of the scanning optical systems includes a synchronous detection optical system that determines a timing to start scanning the scanning surfaces with the light beams. One or more loss prevention indicators are initiated at the patient sensor upon detecting the loss of the patient sensor.
