Abstract:
Orthodontic prosthesis having a seat (3) and an electronic identification device (4), inserted in said seat (3) below its opening (3A). A sealing layer (5) is provided above the electronic identification device (4), to close the opening (3A) in order to retain the device (4) in seat (3), preventing the infiltration of liquids or particles.
Abstract:
An apparatus and a process for performing digital X-ray fluoroscopy on the body of a patient are described, wherein the acquired digital images are subjected to a first step of noise reduction and a second step of geometrical image correction.
Abstract:
This invention relates to a power generator for an ultrasonic welding head made up of an emitter, a mechanical amplifier and a sonotrode, to supply energy to an ultrasonic transducer in the form of a preset alternating amplitude and frequency signal. It comprises, in combination, a power feeder, a power converter, a power transformer, a phase and frequency control device for controlling the power converter, and a micro-controller programmed for digital control of frequency and power of the piloting signal of the ultrasonic transducer, so as to tune the frequency of the generator to that of the emitter and to compensate sonotrode frequency variations.
