The present invention provides a balloon catheter comprising:a hollow inner shaft disposed within a hollow outer shaft;a balloon attached at its proximal end to said outer shaft and at its distal end to said inner shaft;wherein the inner shaft is constructed such that following radial expansion of the balloon to a first expanded state, said inner shaft is capable of responding to further longitudinal expansion of the balloon to a second expanded state by increasing its length from a resting value, and of responding to subsequent partial deflation back to said first expanded state by reducing its length back to said resting value.

A Coriolis mass flowmeter incorporates a measuring tube for guiding a flowing medium, a first oscillator for the oscillatory stimulation of the measuring tube, as well as a first oscillation sensor and a second oscillation sensor for picking up Coriolis oscillations of the measuring tube. The first oscillator, the first oscillation sensor and the second oscillation sensor are mutually spaced apart in the longitudinal direction of the measuring tube and the first oscillator is activated by an oscillation-stimulating control device. A third oscillation sensor is provided and positioned opposite the first oscillator at the same longitudinal distance of the measuring tube. Additionally or alternatively, a second oscillator and a third oscillator may be provided, with the second oscillator positioned opposite the first oscillation sensor and the third oscillator positioned opposite the second oscillation sensor, in each case at the same longitudinal distance on the measuring tube. All mutually opposite oscillators and oscillation sensors are of the same size, resulting in a “balanced” measuring tube while opening up various possibilities for improving the evaluation and control of the flowmeter, which in turn provides greater reproducibility and measuring accuracy.

A linear vibrator is disclosed, the linear vibrator including a case providing an inner space, a first driving unit arranged inside the case, a second driving unit arranged inside the case to be driven to a horizontal direction relative to the first driving unit, and an elastic unit arranged on lateral surfaces opposite the second driving unit to elastically support the second driving unit inside the case.

An electrically controlled turbocharger having a substantially vertically oriented shaft interconnecting a turbine and a compressor. The vertical orientation serves to eliminate the effects of gravity on the rotating components. Placing the turbine vertically above the motor and compressor and provides additional cooling through convection of heat produced by hot exhaust gas flowing through the turbine. A lubricating system utilizes scavenged air from the compressor to draw lubricating oil through internal passages of the motor housing to maintain a desirable oil sump level, ventilate the auxiliary induction motor, and provide pressure to the oil seals of the motor cavity.

Disclosed is a linear vibrator, the linear vibrator including a stator having first and second coil blocks coupled to a bottom plate of a casing, a vibrator having a magnet disposed at a position corresponding to the first and second coil blocks, and an elastic member elastically supporting the magnet.
