Latest Patents

One of Risto's latest patents is a beam balancer for optical data writing. This method involves balancing pulse energies across a series of write beams in an optical data writer. It includes applying an independently controllable phase delay to each write beam, changing its polarization, and directing a selected plane-polarized component through a data modulator onto an optical substrate. This innovative approach allows for modulation of each write beam irrespective of the tolerance across the series.

Another significant patent is for a thin film actuator featuring transversely oriented structural stiffeners. This design increases the actuation stroke resulting from longitudinal curvature. The thin film actuator can be utilized in electromechanical devices, where the deflection of the actuator plate produces the desired actuation stroke. The actuator plate is cantilevered from a rigid frame structure, and the inclusion of a piezoelectric film generates the necessary bending moments for actuation.
