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.

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.

A telecommunications network includes a mobile phone with an audio-modulated vibrotactile module that responds to a telecommunications signal containing information about incoming speech from a called / calling party, for providing an audio-modulated vibrotactile module force containing information about the incoming speech from the called / calling party to vibrate a user's fingers, facial skin, wrist, cheek or other suitable location. The audio-modulated vibrotactile module has an audio-to-vibrotactile converter that responds to the telecommunications signal, for providing an audio-to-vibrotactile converter signal containing information about a vibration modulation of the incoming speech from the called / calling party. The audio-modulated vibrotactile module also has a vibrotactile actuator that responds to the audio-to-vibrotactile converter signal, for providing the audio-modulated vibrotactile module force in the form of a vibrotactile actuator force. The telecommunications system may also have the audio-to-vibrotactile converter. The vibrotactile actuator may be an electromechanical actuator arranged in the housing of the mobile phone for providing vibration to a user's fingers wrist or facial skin.

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 herein is a manufacturing method, excellent in wire drawability, of a seamed flux-cored welding wire having both favorable feedability and low hydrogen content characteristic. The method for manufacturing a seamed flux-cored wire, comprises the steps of: drawing a tube-like formed wire including a flux filled therein using a lubricant; removing the lubricant from the drawn wire by a physical means; and coating a lubricant (coating an oil) for wire feeding on the wire surface. The respective steps are carried out in an in-line manner. In the wire drawing step, a wire drawing lubricant containing a sulfur-bearing high-pressure lubricant is used, and the overall wire drawing from the tube-like formed wire to a roughly product-diameter wire is carried out by means of a roller die.

A horizontal linear vibrator includes: a bracket providing an internal space; a vibration unit mounted in the internal space and making a horizontal, linear movement; a magnetic field unit providing an electromagnetic force to allow the vibration unit to move horizontally; and a cover unit formed to cover an upper portion of the bracket, wherein the bracket includes a support plate part so as to support the vibration unit to make a horizontal, linear movement, and the cover unit is formed to overlap with the support plate part.

An apparatus, system and method for re-canalization or opening a passage through an occlusion in a blood vessel is disclosed. The apparatus and method, which are appropriate for both cardiovascular as well as peripheral vessels, use hydraulic pressure to drive a vibratable member, and the system includes a control unit to permit the frequency or amplitude of oscillation of the vibratable member to be adjusted to suit the morphology or hardness of the target occlusion. Also disclosed is a method for adjusting the force of vibration.

A vibration reducing golf glove, which includes a front panel for covering the inner portion of a wearer's hand and fingers, a thumb section for covering the wearer's thumb which is coupled to the front panel, and a back panel for covering the outer portion of a wearer's hand and fingers. Vibration reducing thick leather is coupled independently to the front panel at the palm, thumb and finger areas for reducing the degree of vibration. As a result, the vibration reducing golf glove provides a reduction in the vibration and shock transmitted to the wearer's and at the time a shock or vibration is applied to the outer surface of the glove.

An apparatus and method for controlling vibration in a mobile terminal are provided. The method includes, upon detecting a key input by a user, determining whether a current feedback signal is detected when an external case with a first vibrator is connected to the mobile terminal, upon detecting the current feedback signal, determining that the external case is connected to the mobile terminal and applying a drive signal to the first vibrator, and controlling the first vibrator to be activated in response to the received drive signal to output a haptic feedback.
