An apparatus is disclosed for measuring one or more parameters of a variable physical structure, at least one of the parameters being fluid level, position, velocity or acceleration. The apparatus includes an electromagnetic sensing element comprising at least two electrically conductive members that are electrically insulated from one another. A distributed capacitance and a distributed inductance are each formed along a length of the sensing element. The inductive reactance is at least ten percent of the capacitive reactance, thereby allowing the capacitance to be distributed, rather than acting as a “lump capacitance”. The distributed capacitance enables shaping of the electric and magnetic fields around the electromagnetic sensing element so that disturbance by nearby electromagnetic fields, conductors, and dielectrics is minimized.When the apparatus is configured as a fluid level sensor, the capacitance is affected by the permittivity and the level of the measured fluid. A reference sensor can be used to compensate for changes in the permittivity of the fluid.When the apparatus is configured as a position sensor, the capacitance and / or inductance are affected by the position of an electrically conductive or dielectric target. The position measurement can be differentiated to obtain measurements of velocity or acceleration. Electronic circuits for operating the sensing element are also shown.

An improved hearing aid device adapted for use within the ear canal of the CIC (Completely In the ear) and of the partially exposed ITC (In The Canal) type. This aid consists of a system of integrated parts allowing an air gap to substantially surround the hearing aid shell and air passages which communicate with the inner ear minimizing occlusion sensations and providing the user with an enhanced natural hearing experience. A key aspect of this device is the provision of air passages in the mounting insert which securely positions the hearing aid shell in the wearer's canal. These passages are designed to stay open after insertion of the aid in the ear canal. In use, unamplified sound from the outside passes around the hearing aid shell, through the air passages in the mounting insert blending with the amplified sound emanating from the receiver. The area of air passages in the mounting insert can be tailored by the technician adapting to the hearing loss characteristics of the user. Surprisingly, acoustic feedback is mitigated in spite of the openness of this novel design.

A device for adjusting the capacity of a beverage cup is provided. The device includes an insertion unit having at least a volume smaller than an interior volume of a cup and a shape in which a lower end portion of the insertion unit comes in contact with a bottom portion of the cup when inserted into the cup. The insertion unit includes a first magnet sealed in a bottom portion of the insertion unit. The device also includes an outer fixed unit to be placed under the cup. The outer fixed unit includes a second magnet sealed in the upper portion of the outer fixed unit for interacting with the first magnet of the insertion unit and securing the insertion unit to the cup by a magnetic force between the magnets.

The present invention provides a method of controlling an actuator assembly for suspension systems. The actuator assembly control method of the present invention is possible to control the actuator assembly according to conditions of vehicle velocity and steering angle or vehicle velocity and steering angular velocity, thus reducing energy consumption, thereby increasing the efficiency of the actuator assembly.
