Abstract: A pop-up laminate structure includes rigid layers, at least one flexible layer, at least one optical component, and an actuator. At least one of the rigid layers defines gaps extending there through to form a plurality of rigid segments separated by the gaps in the rigid layer. The flexible layer is bonded to the rigid segments to form joints for folding. The optical component is mounted to a rigid layer and configured to generate, capture or alter a light beam. The actuator is mounted to at least one of the rigid layers and configured to displace at least one rigid segment that, in turn, displaces the optical component. At least some of the layers are bonded to adjacent layers only at selected locations forming islands of inter-layer bonds to allow expansion of the laminate into an expanded three-dimensional structure.

Abstract: A circuit for driving a plurality of capacitive actuators, the circuit having a low- voltage side, a high voltage side and a fiyback transformer between the two. The low- voltage side comprises first and second pairs of low-side switches connected in series across an input voltage. The fiyback transformer has a primary winding connected to the two pairs of switches. The high-voltage side has a pair of switches connected between the secondary winding of the flyback transformer and a ground and a plurality of capacitive loads and bidirectional switches to connect the loads to the secondary winding of the fiyback transformer and a ground.
