  • Fracture prediction for crystalline microstructures
    Patent number: 7979237
    Abstract: A method for predicting failures in crystalline microstructures is described. Fracture stress distribution data obtained from test samples prepared according to the same manufacturing process as a contemplated device is used to characterize the strength of surfaces in a numerical stress analysis of the device. The reliability is then calculated for surface nodes on the device. The product of all such reliabilities yields the overall reliability (or 1—the overall failure probability) of the device.

  • Video training system
    Patent number: 7920165
    Abstract: A self-viewing environment and an apparatus enabling unrestricted movement of a subject within the self-viewing environment are disclosed. A subject wears a head mounted display that receives a video signal by wireless transmission. The subject is positioned within the field of view of a video camera that sources a video image for transmission to the subject. Video mirror-imaging and signal-processing are employed to adapt the perceived self-viewing environment for the benefit of the subject.

  • Monolithic IC and MEMS microfabrication process
    Patent number: 7875484
    Abstract: Monolithic IC/MEMS processes are disclosed in which high-stress silicon nitride is used as a mechanical material while amorphous silicon serves as a sacrificial layer. Electronic circuits and micro-electromechanical devices are built on separate areas of a single wafer. The sequence of IC and MEMS process steps is designed to prevent alteration of partially completed circuits and devices by subsequent high process temperatures.

  • Low phase noise PLL synthesizer
    Patent number: 7701299
    Abstract: A low phase noise PLL synthesizer is described in which an initial tuning mechanism uses a conventional divider loop to lock a VCO to a desired output frequency. Once initial lock is achieved, the divider loop is switched out of the circuit in favor of a low phase noise mixer loop. The local oscillator signal for the mixer is derived from the same low phase noise source as the phase comparison frequency.

  • Dipole induced transparency drop-filter cavity-waveguide system
    Patent number: 7630604
    Abstract: A normally opaque waveguide interacting with a drop-filter cavity can be switched to a transparent state when the drop filter is also coupled to a dipole. This dipole induced transparency may be obtained even when the vacuum Rabi frequency of the dipole is much less than the cavity decay rate. The condition for transparency is a large Purcell factor. Dipole induced transparency can be used in quantum repeaters for long distance quantum communication.
