Abstract: A system and method for aiding hearing are disclosed. In one embodiment of the system, a programming interface is configured to communicate with a device. The system screens, via a speaker and a user interface associated with the device, a left ear—and separately, a right ear—of a patient. The system then determines a left ear hearing range and a right ear hearing range. The screening utilizes harmonic frequencies of a harmonic frequency series, where the harmonic frequency series includes a fundamental frequency and integer multiples of the fundamental frequency. In some embodiments, the harmonic frequencies may include classical music instrument sounds.

Abstract: A system and method for aiding hearing are disclosed. In one embodiment of the system, a programming interface is configured to communicate with a device. The system screens, via a speaker and a user interface associated with the device, a left ear—and separately, a right ear—of a patient at an incrementally selected frequency within a frequency range, with tinnitus detected frequencies being re-ranged tested to better identify the tinnitus frequencies. The system then determines a left ear tinnitus-impacted hearing range and a right ear tinnitus-impacted hearing range.

Abstract: A submersible pump assembly for transference of a fluid medium with low viscosity is disclosed. In one embodiment, the submersible pump assembly includes a cylinder block having cylinders and pistons. A drive shaft is rotatably supported in the cylinder block and coupled to a drive unit. An inclined leading plate is coupled to the pistons and the drive shaft such that the pistons are configured to be axially driven in a reciprocating motion within the cylinders upon rotation of the inclined leading plate. A suction chamber and a pressure chamber are each located in fluid communication with the cylinders. In one operational mode, the fluid medium is transferred from the suction chamber to the pressure chamber during the reciprocating motion of the pistons, when the pistons are active. In another operational mode, the fluid medium is circulated through the suction chamber.

Abstract: The filling noise generated inside a pressurized container when liquid is injected into the container is detected at the outer end of a vent tube which extends into the container. When the level of liquid in the container reaches the lower end of the vent tube, the filling noise detected at the outer end is abruptly diminished. This abrupt change is detected and used to automatically terminate filling of the tank.
