20110156178 | Micro-Electro-Mechanical System Having Movable Element Integrated into Leadframe-Based Package - A MEMS may integrate movable MEMS parts, such as mechanical elements, flexible membranes, and sensors, with the low-cost device package, leaving the electronics and signal-processing parts in the integrated circuitry of the semiconductor chip. The package may be a leadframe-based plastic molded body having an opening through the thickness of the body. The movable part may be anchored in the body and extend at least partially across the opening. The chip may be flip-assembled to the leads to span across the foil, and may be separated from the foil by a gap. The leadframe may be a prefabricated piece part, or may be fabricated in a process flow with metal deposition on a sacrificial carrier and patterning of the metal layer. The resulting leadframe may be flat or may have an offset structure useful for stacked package-on-package devices. | 06-30-2011 |

20140144013 | MICROELECTROMECHANICAL SYSTEM HAVING MOVABLE ELEMENT INTEGRATED INTO SUBSTRATE-BASED PACKAGE - A method of fabricating a MEMS device is disclosed. A metal layer is provided over a first surface of a substrate including over an opening. The metal layer is patterned to define a membrane segment and a pad, with the membrane segment extending at least partially across the opening. An integrated circuit chip is attached over the opening to the membrane segment and pad, with the integrated circuit separated from an extending portion of the membrane segment by a gap. The integrated circuit chip includes a conductive member so that deflection of the extending portion relative to the conductive member can be measured as a change in capacitance. | 05-29-2014 |
20140192316 | VISION MEASUREMENT AND TRAINING SYSTEM AND METHOD OF OPERATION THEREOF - A binocular viewer, a method of measuring and training vision that uses a binocular viewer and a vision measurement and training system that employs a computer to control the binocular viewer. In one embodiment, the binocular viewer has left and right display elements and comprises: (1) a variable focal depth optical subsystem located in an optical path between the display elements and a user when the user uses the binocular viewer and (2) a control input coupled to the left and right display elements and the variable focal depth optical subsystem and configured to receive control signals operable to place images on the left and right display elements and vary a focal depth of the variable focal depth optical subsystem. In another embodiment, the binocular viewer lacks the variable focal depth optical subsystem, but the images include at least one feature unique to one of the left and right display elements. | 07-10-2014 |
