Patent number: 8861064Abstract: The invention is directed to a device (10, 10a-10d) comprising: a set of on-chip circuits (110-160, 170, 180), each of the circuits configured to generate a magnetic field (300) perpendicular to a planar surface of the set when energized; a ferrofluidic layer (40) interfaced to the planar surface; and a logic circuit (50) configured to selectively energize (200, 200a) one ore more circuits of the set such as to generate a magnetic field at the energized circuits and a deformation (41, 44, 45) of the ferrofluidic layer in response thereto and to modulate optical beams (IR1, IR2) directed to the ferrofluid layer. Preferably, an additional liquid layer (60) is interfaced to the ferrofluid layer, opposite to the on-chip circuits, which is not miscible with the ferrofluid layer. The invention can be applied to micro-display/projection devices, programmable optical reflecting lenses, or to micro-molding applications for surface replication.Type: GrantFiled: November 8, 2010Date of Patent: October 14, 2014Assignee: International Business Machines CorporationInventors: Tobias P.

Publication number: 20090110345Abstract: A method for passive alignment of adapters, enabling high-precision connection between components on a rigid or flexible substrate as part of a printed circuit board (PCB) is provided. Removable alignment structures are positioned in an alignment area on a PCB, where the alignment structures are in accordance with a patterned layer. Alignment pins of a two-part connector are inserted into the holes of the alignment structures such that the two-part connector is aligned with the alignment structures on the substrate, and the two-part connector is a component that comprises an integrated adapter part and ferrule part. The ferrule part of the two-part connector is fixed on the substrate in the alignment area. The adapter part of the two-part connector is removed from the ferrule part of the two-part connector such that the ferrule part remains on the substrate. The alignment structures are removed from the substrate.Type: ApplicationFiled: October 26, 2007Publication date: April 30, 2009Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Roger F.
