Abstract: The present invention relates to a system for mast vibration compensation implemented in a communication system including a first node and a second node. The first node comprises a first adaptive antenna mounted in a mast; a receiver connected to said antenna; and a spatial and temporary processing system. The first adaptive antenna is controlled by a first correction signal generated in the spatial and temporary processing system. The correction signal is based on a parameter that indicates that a radio link alignment with a second node is degrading due to mechanical vibrations in the mast. The invention also relates to a method for mast vibration compensation.

Abstract: An intrastromal corneal insert, including an element with the shape of an arc of circumference with a predetermined angular extension (A) less than 360° and made in inert or biocompatible polymer material, intended to be implanted in the stroma of the cornea for correcting sight defects, said element with the shape of an arc of circumference including first through holes, suitable for allowing organic fluids to pass, having the respective axes perpendicular or substantially perpendicular to the plane defined by the element with the shape of an arc of circumference, and second through holes, suitable for allowing organic fluids to pass, having the respective axes parallel or substantially parallel to the plane defined by the element with the shape of an arc of circumference; the first through holes are arranged alternately with the second through holes, and/or the first through holes are in communication with the second through holes.

Abstract: An RF-FET bias and fast and controlled switching circuit, apt to ensure a good receiving of all signals from all users sharing the same access network. The circuit is software controlled and uses an open loop regulation for fast transitions and a closed loop adjusting for control of output power and thermal compensations.
