Abstract: Systems and methods for displaying advertisements on a portable device that utilizes an Activity-based operating system are described. The method includes receiving an indication that an Activity is being transitioned away from, and determining whether or not the Activity is finishing. Upon determining that the Activity is finishing, the method includes causing an advertisement display routine to be executed immediately, otherwise submitting the advertisement display routine into a processing queue to be executed subsequently. The advertisement display routine displays the advertisement only upon determining that the state of the Activity and the state of the portable device are characterized by one or more predetermined conditions.

Abstract: A fuel cell anode comprises a porous ceramic molten metal composite of a metal or metal alloy, for example, tin or a tin alloy, infused in a ceramic where the metal is liquid at the temperatures of an operational solid oxide fuel cell, exhibiting high oxygen ion mobility. The anode can be employed in a SOFC with a thin electrolyte that can be a ceramic of the same or similar composition to that infused with the liquid metal of the porous ceramic molten metal composite anode. The thicknesses of the electrolyte can be reduced to a minimum that allows greater efficiencies of the SOFC thereby constructed.

Abstract: Methods and designs for providing reduced sensitivity to mirror tilt in Fourier transform spectrometers are disclosed. According to an embodiment for two-directional tilt compensation, the FT spectrometer can include a beam splitter positioned to receive an incoming beam from a light source and split the incoming beam into a first sub-beam and a second sub-beam, a corner-cube retroreflector positioned to receive the first sub-beam from the beam splitter, a dual reflective mirror positioned to receive the first sub-beam from the corner-cube retroreflector at one surface and the second sub-beam at the other surface. An optical path delay can be created using a set of mirrors, tilting the beam splitter and/or a glass cube.

Abstract: A rotor blade assembly includes a shank, an airfoil that is formed integrally with the shank, and a removable platform coupled between said shank and said airfoil via a friction fit.

Abstract: An emergency vehicle transmits a Vehicle Present Signal when in transit on public roads responding to an emergency. The signal can include information relating to the type of emergency vehicle, local highway and terrain data, and the location, speed and direction of travel of the emergency vehicle. When the Vehicle Present Signal is detected by a first vehicle, a functional circuit within the first vehicle calculates the distance between the emergency vehicle and the first vehicle. If the vehicles are within a predetermined distance, a warning signal activates one or more warning systems, thereby notifying the driver of the first vehicle that an emergency vehicle is in the vicinity. A dead-band defined by first and second predetermined distances can be incorporated to prevent rapid cycling of the warning signal.

Abstract: Disclosed is a method for providing secure access to multiple secure networks from a single workstation. The architecture can use multiple layers of protection to isolate applications running at different security levels. The first means of isolation is a virtual machine monitor that isolates multiple operating systems running within separate virtual machines on the host operating system. The second layer is the use of multiple user security contexts on the host operating system to isolate each virtual machine. The third level of protection is a highly secured and restricted host operating system where all unnecessary services are removed and user actions are restricted to just the virtual machine monitor using software restriction policies. Finally, the operating system and virtual machine monitor can be run from read-only media to prevent any changes by an attacker from persisting.
