Additionally, the catheter system includes a drive shaft coupled to the internal rotational cutter.

An auto-focusing device with voice coil motor for position feedback comprises a lens holder, a sensor holder, a permanent magnet set, a yoke and a base. The lens holder holds a lens barrel and is wound around with at least two coils wound in opposite directions. The sensor holder holds an image sensor. The permanent magnet set includes at least two permanent magnets stacked together with opposing poles to form a multi-pole permanent magnet set. The permanent magnet set is furnished on the periphery of lens holder and corresponds to the two coils on lens holder. The permanent magnet set is disposed on the yoke to form a close-loop magnetism so as to increase the density of magnetic lines and the efficiency of magnetic force, save power consumption, and extend the service life of device.

Articulating devices for replacing damaged or degenerated weight bearing joints are provided. The devices may have two or more surfaces that articulate against one another that are coated or fully formed of PEEK or similar materials to provide improved wear capabilities while maintaining sufficient strength to operate in a weight bearing capacity.

A cleaning appliance includes a main body and a collecting chamber releasably held on the main body. The collecting chamber includes a closure member which is movable between a closed position and an open position in which the collecting chamber can be emptied and an actuating member adapted and arranged to release the collecting chamber from the main body and, when the collecting chamber is released from the main body, to release the closure member from the closed position. By providing such an arrangement, a single actuating member can be used to release the collecting chamber from the main body of the cleaning appliance and also to open the closure member to empty the collecting chamber. A single actuating member is less complex, requires less space and is more intuitive for a user to operate.

PCT No. PCT/JP97/00572 Sec. 371 Date Jan. 8, 1998 Sec. 102(e) Date Jan. 8, 1998 PCT Filed Feb. 27, 1997 PCT Pub. No. WO97/31990 PCT Pub. Date Sep. 4, 1997This invention provides a method for reclaiming oil from waste plastic in such a way that thermosetting resins and solid foreign matter in the plastic will not pose a problem. This method greatly reduces the burden of presorting the garbage or industrial waste. To achieve this objective when oil is to be reclaimed from a waste plastic containing chlorine compounds, such as vinyl chloride, the plastic must first be stripped of chlorine. Prior to pyrolysis, while being conveyed forward in a continuous stream, the plastic is mixed with heated sand and/or an additive agent to raise its temperature to 250-350 DEG C. This creates a product which is comprised of a mixture of sand and substantially dechlorinated plastic. The product is mixed with heated sand to heat it directly to a temperature of 350-500 DEG C. It is maintained at this temperature until pyrolysis occurs. In order to obtain high-quality oil with a low boiling point, a first gas/liquid separation process separates the product obtained from the aforesaid pyrolysis into liquid high-boiling point oil, gaseous low-boiling point oil and low molecular-weight gases, and recirculates the liquid high-boiling point oil to the pyrolysis process, and a second gas/liquid separation process separates the gaseous low-boiling point oil and low molecular-weight gases into liquid low-boiling point oil and low molecular-weight gases. The first and second gas/liquid separation process are connected in sequence.

A shoulder arthroplasty kit for shoulder arthroplasty is provided. The kit includes a stem for insertion into the humerus and a first member. The first member has a surface having a convex periphery adapted for articulation with the natural glenoid fossia. The convex periphery includes a first articulating surface defining a generally circular outer periphery of the first articulating surface and a second articulating surface extending from a portion of the circular outer periphery of the first articulating surface. The first member is removably cooperable with said stem. The kit also includes a second member including a portion having a concave periphery. The second member is removably cooperable with the stem. The kit further includes a third member for insertion into the natural glenoid fossia. The third member includes a portion having a convex periphery. The third member is adapted for articulation with the second member.

An improved rear-view device for a motor vehicle includes an electronic device with at least one housing device, comprising at least one floor piece and a cover piece configured to be arranged on the floor piece. The floor piece and the cover piece, in the joined state, delimit an at least almost completely closed cavity. At least one first retaining means of a retaining unit, fixes the housing device in or on the rear-view device. At least one electronic module comprises at least one conductor unit and at least one contact means connected with the conductor unit. The conductor unit is arranged on a surface of the floor piece and/or cover piece and turned towards the cavity. The conductor unit comprises at least one carrier and at least one conductor track applied directly to the carrier. The contact means extends through the cover piece and/or through the floor piece with at least one protruding contact section and is accessible externally. The at least one carrier of the at least one conductor unit is formed at least in sections by a functional surface of the floor piece and/or the cover piece adjacent to the cavity and turned towards the cavity. The cover piece and/or floor piece forms a common component with the at least one first retaining means of the retaining unit.

The invention relates to methods by which radio signals can be transmitted to, and received by, a radio receiver such that the receiver consumes very little power from a battery or energy source. The invention also relates to methods by which radio signals, modulated with data information, can be produced by a transmitter that consumes very little power. The invention is applicable not only to medical implants, but any application requiring a radio receiver to operate with very low power consumption.

A solution for detecting and recovering from a failure in a protected single-fiber passive optical network. A detector is used to detect the degradation in power level of optical signals. Furthermore, the invention discloses a variable symmetric split ratio approach to improve the number of splits (e.g. the number of ONUs). A single-fiber passive optical network is disclosed that uses a plurality of passive nodes connected in the optical fiber between the interfaces, wherein in the passive nodes 2-by-2 splitters/combiners are used to couple optical power from and into the optical fiber at a predetermined split ratio.

An electric pump comprising: a rotor, a wet sleeve surrounding the rotor; and a stator surrounding the wet sleeve and the rotor; wherein the rotor and stator have a magnetic air gap of about 2 mm or less.

A low-resolution image is displayed at high resolution and power consumption is reduced. Resolution is made higher by super-resolution processing. Then, display is performed with the luminance of a backlight controlled by local dimming after the super-resolution processing. By controlling the luminance of the backlight, power consumption can be reduced. Further, by performing the local dimming after the super-resolution processing, accurate display can be performed.

An electromagnetic driven membrane pump has a pump housing inside which at least one pump chamber (15) having at least one intake and outlet is formed and delimited between a gable (1) of the pump housing and at least one completely-sealed membrane (14) attached to a wall (4) of the pump housing and, in an axial direction of the pump housing, to a running axle (13) suspended in at least two separated suspensions in a longitudinal direction of the axle (13). At least one of the suspensions is composed of a flat spring (9) attached to the axle (13) in a radial direction out toward the wall (4) of the pump housing. The axle (13) is composed of magnetic material to be driven by a magnetic field from an electromagnet (7) for oscillation in its longitudinal direction and moving the membrane (14) in corresponding oscillating movement. The flat spring (9) is composed of an inner and at least one outer part, with the inner part attached to the axle (13) and the outer part(s) attached to the pump housing. These parts are connected with one another by two elastic legs, arranged at each side of the point where the spring is attached to the axle (13).
