  • Method and system for non-electric communication in water treatment plants or medical appliances
    Patent number: 11990947
    Abstract: The invention relates to a communications device for non-electric communication between fluidically interconnected devices, the communications device being designed to be mounted in a position in a fluidic overall system formed by the fluidically interconnected devices and to receive and/or emit non-electric signals, in particular in the form of pressure or sound signals, the non-electric signals being transmitted via a line that fluidically interconnects the devices. The invention further relates to a method for non-electric communication between fluidically interconnected devices, the non-electric communication taking place preferably by means of pressure and/or sound signals via at least one line that fluidically interconnects the devices.

  • ULTRASONIC DETECTION OF EAR DISORDERS
    Publication number: 20100069752
    Abstract: An apparatus and method for determining ear fluid viscosity. A transducer is operable to transceive a signal to interact with a fluid-containing portion of the ear. The viscosity of the fluid is determined using the transceived signal.

  • Characterization of middle ear effusion
    Publication number: 20040167404
    Abstract: A method for the detection and characterization of fluid behind the tympanic membrane. More specifically, a method for differentiating between infective and non infective effusions behind the tympanic membrane in animals, particularly humans, and more particularly, human children, based on analysis of the rheological properties of the fluid using an ultrasonic source.
