A gimbal arrangement comprises a socket (6) having a partially spherical inner surface with a first radius; a ball (2) located within the socket and having a partially spherical outer surface with a second radius smaller than the first radius; a first array of electromagnets (5) mounted at the outer surface of the ball; a second array of electromagnets (7) mounted at the inner surface of the socket (6); and means for supplying power selectively to different ones of the electromagnets of the two arrays to support the ball within the socket in a position where the partially spherical surfaces of the ball and socket are substantially concentric about a common center and to control the orientation of the ball relative to the socket.
The idea consists in the preparation of a colored biosensor made of a soft silicon patch coated with colored nanoscale particles made of polystyrene. The silicon patch can be glued or netted to any surface and or material.
A water soluble melanin is produced extracellularly in a most economical manner by a microorganism. The melanin corresponds to eumelanin typical of black, human hair. It has excellent UV light absorbance, protects internal organs against gamma radiation. Studies so far have shown it is safe for use.
