    • Capacitive bulk acoustic wave x, y and z-axes gyroscopes implemented on (100) and (111) silicon substrates are disclosed. Exemplary gyroscopes comprise a handle substrate, a bulk acoustic wave resonator element supported by the handle substrate, and a plurality of electrodes surrounding and separated from the resonator element by very small capacitive gaps. The electrodes can excite and detect at least two degenerate bulk acoustic wave resonant modes in the resonator. Advantages include reduced size; higher Q, which improves noise and bias stability; larger bandwidth, and improved shock resistance. In addition, the high Q is maintained in atmospheric or near-atmospheric pressure which reduces the cost and complexity of the wafer-scale packaging of the gyroscope.

    • Disclosed are apparatus that implement blind selected mapping techniques that provide for crest factor reduction of forward link CDMA signals. Communication signals are processed using a mathematical algorithm that selectively maps a summed communication signal in a frame to another summed communication signal which has a smaller peak-to-average power ratio. The reduced dynamic range communication signal is amplified and transmitted to a receiver. At the receiver, the reduced power communication signal is processed using a mathematical algorithm that detects the selected mapping index used in the transmitter and converts the received signals into the original communication signals.

    • An aircraft comprising a Channel Wing having blown channel circulation control wings (CCW) for various functions. The blown channel CCW includes a channel that has a rounded or near-round trailing edge. The channel further has a trailing-edge slot that is adjacent to the rounded trailing edge of the channel. The trailing-edge slot has an inlet connected to a source of pressurized air and is capable of tangentially discharging pressurized air over the rounded trailing edge. The aircraft further has a propeller that is located in the channel and ahead of the rounded trailing edge of the channel. The propeller provides a propeller thrust exhaust stream across the channel wing to propel the aircraft through the air and to provide high lift. The pressurized air being discharged over the rounded trailing edge provides a high lift that is obtained independent of an aircraft angle of attack, thus preventing the asymmetry, separated flow, and stall experienced by the CC wing at the high angle of attack it required for high lift generation. The aircraft can further include blown outboard circulation control wings (CCW) that are synergistically connected to the blown channel CCWs. The blown outboard CCWs provide additional high lift, control thrust/drag interchange, and can provide all three aerodynamic moments when differential blowing is applied front-to-rear or left-to-right. Both the blown channel CCW and the outboard CCW also have leading-edge blowing slots to prevent flow separation or to provide aerodynamic moments for control.

    • A real-time system and method for measuring stickies by separating high molecular weight non-fibrous species from low molecular weight non-fibrous species and sensing the concentration of the high molecular weight species. Specifically, a fiber slurry containing stickies is filtered to remove fibers, fiber debris, and other large contaminant particles from the fiber slurry, after which the carbon content of the filtered sample is measured. Next, the filtrate is ultrafiltered to separate stickies having a high molecular weight from the filtrate, and subsequently, the carbon content of the ultrafiltered sample is measured. Finally, the carbon contents are used to determine the microstickies concentration in the fiber slurry.
