An integrated vehicle operator monitoring system for a vehicle including a device for monitoring operator identity to ensure a vehicle operator is authorized to operate the vehicle, a device for monitoring operator intoxication, and a device for monitoring operator drowsiness. There is also a device for preventing the operator from operating the vehicle when the operator identity monitoring device indicates the operator is not authorized to operate the vehicle and/or the operator intoxication monitoring device indicates the operator is intoxicated. In addition, an alarm capable of being activated when the operator drowsiness monitoring device indicates the vehicle operator is drowsy, is included.

A continuous wave ultrasonic tracking system using an ultrasonic transmitter acoustically radiating a continuous wave ultrasonic transmitted signal and an ultrasonic receiver detecting the transmitted signal as a received signal. The system mixes the transmitted and received signals to create an interference pattern characterized by interference fringes, counts the number of the fringes by which the pattern changes with respect to a fixed point and stores the number as a number of wavelengths of the displacement between the transmitter and receiver, interpolates a location of the fixed point between successive ones of the interference fringes as a fraction of a wavelength and stores the fraction of a wavelength and computing the displacement by combining the number of wavelengths and the fractional number of wavelengths.

An advanced aircrew protection system comprising a helmet assembly adapted to sustain a full pneumatic pressure within the helmet adjacent to the head of the wearer; a suit assembly adapted to sustain a pressure adjacent to selected parts of the body of the wearer; a neck shroud operatively coupled with the helmet assembly and the suit assembly and adapted to pneumatically isolate the helmet assembly from the suit assembly; and controller adapted to independently supply fluid under pressure to the helmet assembly and to the suit assembly. Within the helmet is a dual compartment for an independent supply of fluid to an oral nasal mask separate from the remainder of the helmet assembly.
