The invention concerns a shoulder prosthesis assembly comprising a meta-glenoid element (7) formed by a plate (13) provided with a central tubular block (14) an anchoring members in the glenoid cavity (3), and a glenoid sphere (9) designed to top the metaglenoid element and provided with an axial screw (35) screwed into said pin; the glenoid sphere has an articulated surface (11) designed to co-operate with a cup of an associated humeral prosthesis (2); said assembly comprises means (16, 45, 46; 51, 50, 49) guiding the glenoid sphere adapted to facilitate its being fixed on the meta-glenoid element; said means comprise a pin (46) adapted to be slotted into the tubular block (14) and into an axial passage of the screw (35); the glenoid sphere (9) is thus guided by being slid on the pin (46) until the screw (35) is inserted precisely into the axis of the tubular block (14), wherein it can be screwed without any risk of damaging the thread on the screw and the internal thread of the block. Advantageously, the free end (48) of the screw (35) can likewise be bevelled to facilitate its being inserted in the block (14) without damaging the threads. The inventive arrangement is particular useful considering the difficulties encountered by the surgeon for correctly positioning the glenoid sphere (9) relative to the meta-glenoid element (7) owing to lack of visibility.

The method uses a common optical, system and sequentially creates structures of different sizes in a polymer substrate by means of different laser processes is described. One process uses a laser beam that is tightly focussed on the substrate surface and is used for creating fine groove structures by semi-continuous direct write type beam movement. The second process uses a second laser beam that is used to form a larger size image on the substrate surface and is used to create blind pads and contact holes in the substrate in step and drill mode. A third optional process uses the second laser beam operating in direct writing mode to remove layers of the substrate over larger continuous areas or in a mesh type pattern.

A bracket for orthodontic treatments comprises a closing spring, which is fixedly anchored at the bracket and which covers an arch wire slot formed in the bracket for receiving an arch wire in a closed position. In an end section of the closing spring covering the slot, a tongue is formed in the center and folded at an angle toward a base plate of the bracket. The spring has an end section which is held by projections formed at the bracket structure to secure the spring in its closed position. The spring may be dimensioned and pre-tensioned in a manner that an arch wire inserted into the slot is torqued by the closing spring with forces from the top and from the side.

The invention relates to a system for fastening the bridge (30) or the hinge elements (10, 20) connecting the temples (A) to the lenses (L) of eyeglasses, where the ends of the bridge (30), as well as each of the ends (12, 22) of the temple connecting hinge elements (10, 20) which is directed towards the respective lens is furnished with a respective fork-shaped structure, with at least one pair of prongs (33-34, 36-37, 13-14, 23-24) lying in the plane at right angles to the plane of the lenses and where each lens is provided with holes (61-62, 63-64) located at the points of connection with the ends of the bridge (30) and/or of the temple connecting hinge elements (10, 20). The holes are equal in number to the number of prongs on the respective fork-shaped structures and comprise, inside them, respective tubular sleeves (53, 54). The prongs of each fork-shaped structure are pressed into the tubular sleeves, are flat, and have lateral walls (13a-13b, 14a-14b, 23a-23b, 24a-24b, 33a-33b, 34a-34b, 36a-36b, 37a-38a) which are flat and smooth and other walls which are knurled.

An integrated semiconductor memory includes a storage medium (6) arranged between two electrodes (10, 20), which storage medium may be a phase change medium, for example. The storage medium (6) can be put into a first state or a second state by means of an electric current, as a result of which an item of information can be stored. According to embodiments of the invention, a layer plane (L) is provided in which impurity particles made from a material (4) are embedded, as a result of which the current density in the storage medium is locally increased and the programming current required for reprogramming is reduced. As a result, the current consumption of memory elements containing a phase change medium is reduced, so that for the first time they can be embodied with minimal feature size, together with other components such as transistors, and integrated into a single semiconductor circuit and no longer have to be arranged in separate subcircuits.

The invention concerns a method for making smart cards capable of operating with or without contact called mixed cards and contactless smart cards. In order to avoid the risk of deteriorating the antenna the method consists in producing an antenna comprising at least two turns, on a support sheet, said antenna having its turns located outside the connecting pads, and in providing an insulating bridge so as to connect each of the antenna ends to a connection pad respectively.

A device is provided for performing intra myocardial injections. The device comprises a needle, a catheter formed with a lumen, and an inflatable abutment member. The abutment member is movable between a first configuration, wherein it is substantially tube-like and is deflated, and a second configuration, wherein it inflates beyond the distal end of the catheter and extends radially. Before the needle is advanced to perform an injection, the abutment member is moved to its second configuration to prevent contact between the catheter and the myocardial tissue during the injection.

The invention concerns a component (1) for motor vehicles, in particular, instrument panel, lateral covering or side member covering, comprising an airbag cover (2) arranged in the region of the filler channel (3) and having a weaker resistance zone opening when the airbag is inflated. The covering zone located on either side of the weaker resistance zone can move freely, from an extracted airbag, along a clearance path while remaining linked to the component 91), after the airbag has been inflated, in specific manner. The airbag cover (20) is an elastic material. The weakened resistance zone extends over the opposite delimitations (4, 5) of the filler channel 93), so as to ensure the extension and inflation of the airbag. Said device eliminates possible damage to the inflated airbag and injury risks incurred by passengers as result the burst parts projected coming from said cover.

An aircraft wing assembly comprising a wing (2) having a wing box structure including an upper wing cover (7) and a lower wing cover (8), and a wing tip device (1) attached to the outboard end of the wing, the wing tip device including an upper cover (9) and a lower cover (10), wherein a gap (g) between opposing edges of the wing tip device lower cover (10) and the lower wing cover (8) is at least 5 mm, and further comprising a seal assembly (20) for aerodynamically sealing the gap (g), wherein the seal assembly (20) includes a bridging component (21) on an interior side of the gap (g), and a seal (22) which fills the gap (g) and is supported by the bridging component (21). Also, an aircraft having the wing assembly, and a method of attaching a wing tip device (1) to the outboard end of a wing (2).

This invention relates to an electrophoretic display comprising cells which are filled with charged particles dispersed in a solvent and are individually sealed with a polymeric sealing layer.

Provided is a hairstyling appliance for styling hair, comprising a first housing and a second housing facing the first housing; the housings, of longitudinal axis, being connected in a pivoting manner by a hinge so as to define an open and closed position of the appliance; the first housing having a first hair treatment surface which is intended to be heated by a first heating means; the second housing having at least one second hair treatment surface which is intended to come into contact with the first surface in order to grip the hair in the closed position; the appliance containing two cylinders arranged on each side of one of the treatment surfaces, the cylinders being mounted so as to be able to rotate about their longitudinal axis.
