摘要： A fluidic component for generating an ultrasound signal is provided. The fluidic component includes a flow chamber, which can be flowed through by a fluid flow, which enters the flow chamber through an inlet opening of the flow chamber and exits from the flow chamber through an outlet opening of the flow chamber. The fluidic component has at least one device for forming an oscillation of the fluid flow at the outlet opening, the oscillation taking place in an oscillation plane, a separation device, which is designed to separate off a part from the oscillating fluid flow. The separation device includes an inlet opening, through which the oscillating fluid flow enters the separation device, and at least one first outlet opening and at least one second outlet opening, through each of which a part of the oscillating fluid flow exits.

摘要： Underwater vehicles may fix their position from GPS at the surface of the water and use bottom track for dead reckoning once it has descended to within tracking range of the bottom of a body of water. This disclosure describes a method and system for navigation through the water through depths where GPS is not available using current profiles from sonar systems including acoustic Doppler current profilers (ADCP). This extrapolation of earth referenced current profiles can provide a way to estimate vehicle motion below the surface before the vehicle reaches the bottom. Once bottom track is achieved, the corrected reference for vehicle motion improves the vehicle position estimate. A Kalman filter updates vehicle position and current profile estimates during descent, and the bottom track when the bottom comes within range to enable navigation of underwater vehicles.

摘要： An angular velocity sensor utilizing the Coriolis effect on a fluid jet employs increased spacing between the sensing elements to increase the scale factor and to reduce flow disturbances. A metal diaphragm pump is utilized to improve the ability to control the flow rate. Flow disturbances are further reduced by using a single, symmetrical central flowhole, eliminating curtain holes, and providing only two discharge paths oriented 180.degree. apart.

摘要： A device for measuring the rotational speed of a rotating object in which atream of fluid from a back pressure sensor is directed at a chopper wheel attached to the rotating object. The output of the back pressure sensor varies as the chopper wheel rotates. The number of variations in pressure per unit time is directly proportional to the rotational speed of the rotating object.

摘要： A pressure-to-electric output system is used to convert the dual outlet pressure signals of a fluidic angular rate sensor to a pair of oscillating electrical signals whose relative frequency differential is very accurately indicative of the sensor outlet pressure differential. The sensor outlets are fluidically coupled to the control ports of the first amplifier in a cascaded series of fluidic proportional amplifiers. The outlet ports of the terminal amplifier are coupled to the inlet ports of a pair of fluidic oscillators. A pair of microphone type pressure-to-electric transducers are driven by the oscillators to produce the oscillating electrical signals.
