A switchable rotation drive device has a switching mechanism wherein a first connecting sleeve that always rotates integrally with a motor hollow rotor, and a second connecting sleeve that always rotates integrally with a planetary carrier of a planetary gear reduction mechanism are connected via a bearing in a relatively rotatable state, and the first connecting sleeve is formed with a sun gear. By sliding the switching mechanism, the output shaft can be switched between high-speed rotation and low-speed rotation. In comparison to a case in which the entirety of the planetary gear reduction mechanism is made to slide, the sliding region may be smaller, and the required space needed to allow sliding may also be smaller. Therefore, it is advantageous to reduce the size of the device and make it more compact.

A cooled electrosurgical system includes an electrosurgical device having at least one electrode for applying electrical energy to tissue. In one embodiment, the electrode includes an internal cavity in which a cooling medium such as water is contained. The internal cavity is closed at both ends of the device such that the cooling medium is contained within the electrode at the surgical site such that the cooling medium does not contact the tissue being treated. The electrosurgical device has an electrode and a heat pipe to conduct heat from the electrodes where substantially all heat conducted from the electrode through the heat pipe is dissipated along the length of the heat pipe. The heat pipe can have a thermal time constant less than 60 seconds and preferably less than 30 seconds.

The invention, in various embodiments, is directed to a solid-state flow generator and related systems, methods and applications.

A device for displaying images positions a luminescent material between a light source and a liquid crystal display (LCD). The light source, which comprises one or more nonpolar or semipolar III-nitride based light emitting diodes (LEDs), emits a primary light having a specified polarization direction and comprising one or more first wavelengths. This primary light emitted by the light source is a linearly polarized light that eliminates any need for a polarizer. The luminescent material, which comprises one or more phosphors, is optically pumped by the primary light and emits a secondary light having the polarization direction of the primary light, wherein the secondary light is comprised one or more second wavelengths that are different from the first wavelength. This secondary light emitted by the luminescent material is a colored light that eliminates any need for a color filter. The LCD receives the secondary light and displays one or more images in response thereto.

The invention provides a simple method, devices and several machines for simultaneously stirring and aerating thousands of vessels or wells of microplates in a robust manner and with economy. This method uses the simple principle of magnetic stirrers being levitated vertically when passed laterally or vertically through a strong horizontal dipole magnetic field. The dipole magnetic fields may be produced by using permanent magnets, electromagnets or a modulating/reversing electro-magnetic field. Each vessel contains a magnetic ball, disc, bar, dowel or other shape (stirrers) which in their magnetic attraction to the dipole magnetic field will cause the stirrers to levitate up in the vessel as the stirrer's magnetic poles attempt to align with the center of the dipole's magnetic field. The stirrers will fall to the bottom of the vessel by gravity or by changing the relative position of the levitating magnetic field to pull them down, or by passing the vessel laterally over another magnetic field. The up and down movement of the stirrers provides a vigorous mixing of the contents of many vessels at same time. If the level of the vessel's meniscus is situated so the stirrers pass through it on their way up and down, the air/liquid interface is significantly increased thereby significantly increasing aeration of the liquid.

An electronic cigarette built in a power supply rod comprises a suction rod and the power supply rod connected mutually as a whole. A connecting end of the suction rod is provided with a first connector. A connecting end of the power supply rod is provided with a second connector. The power supply rod extends from the connecting end of the suction rod and is accommodated and fixed in the suction rod. The connecting end of the suction rod and the connecting end of the power supply rod are fixedly connected by using screw threads of the first connector and the second connector. The length of the electronic cigarette becomes smaller, the structure is more compact, disassembly and assembly are convenient, and the amount of smoke is great, thereby helping observe the residual of tobacco liquid and making a smoker reduce the suction of the tobacco liquid or making the smoker avoid sucking the tobacco liquid.

A neural network type of apparatus is provided to detect an internal state of a secondary battery implemented in a battery system. The apparatus comprises a detecting unit, producing unit and estimating unit. The detecting unit detects electric signals indicating an operating state of the battery. The producing unit produces, using the electric signals, an input parameter required for estimating the internal state of the battery. The input parameter reflects calibration of a present charged state of the battery which is attributable to at least one of a present degraded state of the battery and a difference in types of the battery. The estimating unit estimates an output parameter indicating the charged state of the battery by applying the input parameter to neural network calculation.

A light guide with input and output faces 2, 3a is polar-symmetric about the first face 2 and has optical properties such that the angle at which a ray is injected into the first face determines the position at which it leaves the second face 3a, or, if operated in the reverse direction, the position at which the ray enters the second face determines the angle at which the ray leaves the second face. The light guide includes a tapered transparent sheet 3, light from the first face entering at the thick end of this sheet, and the second face forming one face of the tapered sheet. An input/output slab 4 adjoins the tapered sheet 3 for fan-out of light from the first face 2 to the tapered sheet, and a transition region 8 is located between flat and tapered sheets. The polar symmetry means that light rays always travel in line with the taper direction, which suppresses banding. Preferably the light guide further includes a prism device 20 for folding the light so that the flat and tapered sheets can be folded over each other. A method of making such a prism is also disclosed.

3-degrees-of-freedom universal joints UJ1 and UJ2 for allowing the hand H1 to make up-down swing motions D1 and side-to-side swing motions D2 are joined to the top right and left parts, respectively, of the wrist portion of the hand H1, and a 2-degrees-of-freedom universal joint UJ3 for allowing the hand H1 to make twisting rotations D3 is joined to the wrist portion of the hand H1 so as to serve as the center of 3-degrees-of-freedom.

Presently, many variations of light treatment are used in health care. Prime examples are the in-vivo or ex-vivo photodynamic treatment (PDT) of skin diseases, cancer/tumors, psoriasis, mood disorders, bladder infections, promoting wound closure, recovering spinal cord injuries, and countering muscle/bone atrophy. PDT is a treatment that uses a drug, called a photo-sensitizer or photosensitizing agent, and a particular type of light. The invention relates to an improved PDT device.

The present invention relates to liquid drug medical devices for enabling the administration of liquid drugs, and also a needle shield removal device for safely removing needle shields.
