The present invention relates to a finger musical instrument, including a first glove and a second glove, some performance keys distributed on a fingertip of each of the gloves, and a sound box positioned at each of the gloves. The finger musical instrument further includes a combination key positioned at palm heel of each of the gloves. Each of the sound boxes is connected with a controller. The performance key and the combination key on the same glove are all connected with the corresponding controller. Therein the performance key and the combination of the performance key and the combination key of one glove gives out one octave sound, while the performance key and the combination of the performance key and the combination key of the other glove gives out another octave sound. Each of the controllers is provided with a range regulation switch used for making a sound higher or lower by an octave on each of the gloves. With regulation of the range regulation switch, the finger musical instrument is able to give out a range of two octaves through the sound box. The finger musical instrument of the present invention covers a range of three octaves and can exhibit a vivider music, and the controller can switch between a performance mode and a teaching mode, thus enhancing interaction between the finger musical instrument and a performer.

Organo-metallic complexes for opto-electronic and sensory devices and their use in such devices are provided. The organo-metallic complex (triplet emitter) consists of a metal center and chelate ligands. At least one of chelate ligands comprises an aromatic or fused aromatic ring(s). Each ligand is covalently substituted with at least one, preferably two charge transport groups (ctg). The metal center can be coordinated by a spectator ligand. Presence of two ctgs at each ligand is advantageous for applications in organic light emitting diodes (OLEDs). Charge transport units facilitate hole and / or electron transport to the molecular center and allow for efficient exciton formation directly on the complex. Presence of ctgs on each ligand provides a good shielding with respect to interactions with the environment. Emission quenching is strongly reduced and materials with high emission quantum yields are obtained. Presence of ctgs on each ligand reduces undesired quenching by triplet-triplet annihilation or self-quenching effects.

An apparatus and method for micro-exercise apply piezoelectric stress to cells of a bone mass by inducing voltages in the bone mass. Application of dynamic, electromagnetic fields passing through the conductive bone mass induce currents and voltages locally in and around cells or groups of cells. The cells respond to the combination of mechanical stress and strain by building themselves up as they would if they had been subjected to the stress and strain of conventional exercise. Thus, micro-exercise at a cellular level of the bone mass can be stimulated as if the stress and strain had been applied to the entire bone structure of which the smaller cellular portions are constituent parts. In combination with casts or splints, the sources of electromagnetic flux may be embedded in the frame or solid structure, the protective padding added for comfort, or both.

Rolling bearing cage (5) for an electric steering system of a motor vehicle, designed to ensure the circumferential spacing of the balls (4), comprising a plurality of first sockets (8) provided with means (8a) for axially retaining the cage (5) on a ball (4) and a plurality of second sockets (9) without means for axially retaining the cage (5) on a ball (4). Each of the first sockets (8), with a ball (4) housed in the first corresponding socket (8), has a first axial clearance, a first radial clearance and a first circumferential clearance (J1c) and each of the second sockets (9), with a ball (4) housed in the second corresponding socket (9), has a second axial clearance, a second radial clearance and a second circumferential clearance (J2c).
