Abrégé

The invention relates to an optical assembly for use with compact camera modules. The optical assembly comprises a transparent optical element, an optical reflection surface arranged to deflect a light through the optical element, a transparent elastic non-fluid body and an actuator system comprising one or more actuators and an actuator-component arranged to undergo bending and/or displacement by the one or more actuators. The non-fluid body may be sandwiched between the actuator-component and the optical element so that the shape or orientation of the actuator component and the non-fluid body can be changed by actuation of the actuators to provide adjustable optical power or beam deflection.

Abrégé

The invention relates to an electronic circuit (100) for controlling charging of a piezoelectric load (190). The electronic circuit comprises a charge pump (111) configured to supply a charging current to the piezoelectric load dependent on a charge control signal (131), a measurement circuit (113) configured to obtain a load voltage corresponding to a terminal voltage at a load terminal of the piezoelectric load, a comparator circuit (114) configured to compare an adjustable reference voltage with the load voltage. The electronic circuit is configured to determine the charge control signal dependent on the comparison so that the control signal controls delivery of the charging current dependent on the comparison. The electronic circuit is further configured to set the adjustable reference voltage to a target voltage (VT) and to set the adjustable reference voltage to a low limit voltage (Vlow), being lower than the target voltage, when the load voltage reaches the target voltage.
