Shock-absorbing intervertebral implant

The invention relates to an intervertebral implant comprising a spacer designed to be applied between two spinous processes of two vertebrae. The spacer comprises: two elements (10, 12) made of a first material, and each presenting a first end (10a, 12a) and a second end (10b, 12b), said first end (10a, 12a) being securable to a spinous process; and a connection piece (14) made of a second material of greater elastic deformability than said first material, said connection piece interconnecting said second ends (10b, 12b) of said two elements (10, 12) so that the stresses that are exerted on said two elements (10, 12) are damped, and said connection piece enabling said intervertebral implant to limit and brake the relative movements of said vertebrae.

The present invention provides a wirelessly-chargeable heating pad, which is coupled to an article in a removable manner and is used in combination with a charging device to perform wireless electrical charging. The wirelessly-chargeable heating pad includes a receiver circuit, a heating element, and a pad body. The receiver circuit includes a rechargeable battery. The heating element is electrically connected to the rechargeable battery. The heating element and the receiver circuit are both mounted to the pad body. The article includes a removable mounting structure, so that the wirelessly-chargeable heating pad is removably coupled to the article through the removable mounting structure. The charging device, after receiving electrical power, converts the electrical power into an alternate current signal that is transmitted to the receiver circuit. The receiver circuit receives and converts the alternate current signal into electrical power that is then stored in the rechargeable battery. The rechargeable battery subsequently supplies the electrical power to the heating element to give off heat.

System, array and non-porous solid support comprising fixed or immobilized nucleic acids

Nucleic acids are fixed or immobilized to non-porous solid supports (substrates), and include systems containing such supports and arrays with fixed or immobilized nucleic acids. These compositions are useful for nucleic acid analyses and a host of applications, including, for example, detection, mutational analysis and quantification. The non-porous solid supports can be transparent or translucent, and the surfaces can be treated with agents to fix or immobilize the nucleic acids. Such agents include, for example, amine providing compounds, epoxy compounds and acid solutions. The fixed or immobilized nucleic acids can be unlabeled, or labeled with at least one non-radioactive signaling moiety, such as the case when the nucleic acids are double-stranded.

Modular LED lighting systems and flexible or rigid strip lighting devices

The present invention relates to lighting strips and more particularly to modular lighting systems comprising lighting devices, for example, lighting strips, physically and electrically connectable with one another by way of a plug and socket integrally formed at opposing ends of the lighting strips. The lighting strip devices can be made of flexible material to allow for applying the lighting devices along flat as well as contoured surfaces. The lighting strips can also be rigid. More particularly, embodiments of the invention include modular lighting strips comprising: a non-conductive substrate strip comprising an electrical circuit; a plurality of light sources operably connected to the electrical circuit; a plug integrally formed at an end of the substrate strip; and a socket integrally formed at an opposing end of the substrate strip; wherein the plug and socket provide for removable, friction-fit, latch or latchless, and electrical interconnection of two or more circuits. Also included in the invention are connector assemblies comprising the inventive socket and plugs integral to PCBs for use in the field of electronics. One or more lighting strip can be combined to form lighting systems, which are useful in many functional and decorative lighting applications. The lighting systems are useful for any residential or commercial application where modular, discrete, low-profile, and/or flexible lighting is desired. The lighting strips of the invention can be used in particular for back lighting, accent lighting, aisle or path lighting, contour lighting, elegant interior decoration, holiday decorations, or landscape lighting.

Etching apparatus for manufacturing semiconductor devices

An etching apparatus for manufacturing semiconductor devices which reduces contamination of the processing surface of a wafer by transporting a plurality of wafers stacked in a cassette with their processing surfaces facing down from the cassette supply chamber to one or more process chambers where the etching operation is performed on each wafer, one at a time. The apparatus has a load lock chamber for transferring the wafers stacked in the cassette from the cassette supply chamber, which is maintained under atmospheric conditions, to the process chamber, which is maintained under a strong vacuum. The process chamber has a cathode to which a wafer is clamped by a wafer holder with its processing surface facing down; the process chamber may also have a removable lower cover for easy repair and cleaning. The apparatus may also have a wafer aligning chamber installed between the cassette supply chamber and the load lock chamber for simultaneously aligning all of the wafers n the cassette before they are transported to the load lock chamber. The wafer aligning chamber also has a cassette transport mechanism for transferring the cassette from a cassette supply table in the cassette supply chamber to an elevator installed in the load lock chamber.
