| 20100239940 | System and Method for Manufacturing Fuel Cell Stacks - A method of manufacturing a fuel cell stack is provided. The method provides forming an inspectable preassembly of multiple fuel cell assemblies that may be termed a pseudostack. Each fuel cell in the pseudostack has permanent electrical interconnections and sealing connections on only one of the two electrodes, namely an anode layer or a cathode layer. For example, an anode interconnect may be firmly attached to the anode layer by means of a bonding agent and a sealing agent used to seal passages on the anode layer of the fuel cell. Alternatively, seals and permanent electrical connections may be made on the cathode layer of the fuel cell, and not on the anode layer. | 09-23-2010 |

| 20090051369 | SYSTEM AND METHOD FOR MEASURING ADHESION FORCES IN MEMS DEVICES - A MEMS test device comprises a flexible beam spaced apart from an optical stack. The MEMS test device includes a reflective layer and a partially reflective layer, such that a change in the position of the MEMS test device can be observed without the use of an external interferometer. The flexible beam may be cantilevered or fixed at each end. The flexible beam may include a shoe suspended from the side of the beam facing the optical stack, to provide a fixed contact area. An array of MEMS test devices may be used to determine compliance, or to calculate adhesion forces. | 02-26-2009 |
| 20090195856 | METHODS OF REDUCING CD LOSS IN A MICROELECTROMECHANICAL DEVICE - Methods of fabricating an electromechanical systems device that minimize critical dimension (CD) loss in the device are described. The methods provide electromechanical systems devices with improved properties, including high reflectivity. | 08-06-2009 |
| 20090231666 | Microelectromechanical device with thermal expansion balancing layer or stiffening layer - An interferometric modulating device is provided with a thermal expansion balancing layer on a side of the movable flexible layer opposite the movable reflector such that when temperature changes the distance between the movable reflector and the optical stack does not change significantly, thereby leading to stable color. Additionally, an interferometric modulating device is provided with a stiffening layer between the movable flexible layer and the movable reflector and at least one hollow void exists on the surface where the movable reflector and the stiffening layer contact each other so that the movable reflector is more rigid to bending, thereby reducing the temperature sensitivity of the movable reflector. | 09-17-2009 |
