20150350500 | MOVING IMAGE SENSOR PACKAGE - A moving image sensor package is provided that may be used to provide optical image stabilization (OIS) in the same form factor as non-OIS enabled image sensors utilized in portable/mobile devices. The moving image sensor package includes an image sensor attached to a MEMS actuator mounted within a cutout in a circuit board, wherein the MEMS actuator has substantially the same thickness as the circuit board. | 12-03-2015 |
20150341534 | ELECTRICAL BAR LATCHING FOR LOW STIFFNESS FLEXURE MEMS ACTUATOR - A MEMS actuator including buckled flexures and a method of assembling the actuator are described. The assembled MEMS actuator includes an inner frame; an outer frame including latched electrical bars, where a first of the latched bars includes a latch protrusion secured to a corresponding latch groove of a second of the latched bars; and buckled flexures coupling the inner frame to the outer frame. The flexures are buckled during assembly of the MEMS actuator by incorporating the electrical bar latching mechanism into the design of the outer frame of the MEMS actuator. In one implementation, the MEMS actuator is assembled by providing a MEMS actuator with unbuckled flexures coupling the outer frame of the MEMS actuator to an inner frame of the MEMS actuator, where the outer frame includes unlatched electrical bars, and latching the electrical bars of the outer frame, resulting in buckled flexures. | 11-26-2015 |
20150334277 | MEMS BASED DUST REMOVAL FOR IMAGE SENSORS - Systems and methods provide dust removal on an image sensor surface of a digital camera. Dust removal can be achieved by either imparting vibrational movement on a stage upon which the image sensor is mounted and/or by moving the stage towards one or more impact stops. The vibrational movement may shake loose any contaminants present on the image sensor. The impact of the stage at the one or more impact stops also may shake loose any contaminants present on the image sensor. | 11-19-2015 |
20150321900 | LOW STIFFNESS FLEXURE - A flexure includes a support first end connected to a first frame; a support second end connected to a second frame; and a buckled section connecting the first support end to the second support end. The length of the flexure is substantially greater than its width, and the width of the flexure is substantially greater than its thickness. During operation, the flexure is maintained in a buckled state where the flexure's stiffness is significantly less than in the unbuckled state. In one implementation, a stage includes a flexure array joining a first frame and a second frame, where: the first frame and the second frame are substantially on a plane; the flexure array is substantially on the plane prior to buckling by the flexures of the flexure array; and the flexure array is bent substantially out of the plane after buckling by the flexures. | 11-12-2015 |
