Patent number: 8149956Abstract: An automatic zero-crossing signal demodulation and classification device for rapidly identifying an unknown modulation in a signal identifies an unknown modulation in a signal, demodulates differential phase shift keying signals and automatically recognizes certain phase shift keying signals. This is accomplished by eliminating the unknown term fc in differential phase estimation, introducing a symbol rate tracking mechanism, applying hysteresis nonlinearity to eliminate the phase shaping effect and using a weighted average to estimate the phase difference. Better estimates are accomplished by using the hysteretic nonlinear function to detect the zero-crossing points in eliminating the false detecting of the zero-crossing points caused by the additive noise, and calculating differential phase without directly using the center frequency to simplify the estimation process.Type: GrantFiled: April 23, 2007Date of Patent: April 3, 2012Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Wei Su

Patent number: 8020432Abstract: A rigid, planar, non-resonating boundary is introduced parallel to the surface of the piezoelectric resonator in a measurand chamber in order to both reduce the separation space (l) between the resonator and confining wall and confine the measurand fluid between those surfaces in order to reliably measure acoustic viscosity independently form the mass density (?) of the measurand fluid. The hypothesis is that when the penetration depth (?) is comparable to the separation distance (l) between the resonator and the confining wall, then resonator perturbation is a sensitive function of the abbreviated separation space. Variations in the spacing between the resonator and confining wall are accomplished by adjusting the rigid, planar, non-resonating boundary, or confining wall, with a means for lateral movement. The ability to accurately adjust and control small spaces thereby enables MEMS versions of viscometers and associated types of fluid sensors.Type: GrantFiled: April 29, 2009Date of Patent: September 20, 2011Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Arthur Ballato

Patent number: 7961138Abstract: A detector apparatus, detection system, and method are provided for determining optimum operational angles based on the statistical correlation of wavelength-specific electromagnetic propagation and surface interaction. These techniques can be used within the radar community in both military and commercial radar applications for airborne radar system users to determine optimum operational depression angles based on the purpose of the effort, the operational frequency, and the terrain-type to be encountered. The method requires the user to interface with a standard computer equipped with the commercially available MATLABĀ® software package where the operation is presented as a graphic user interface (GUI) that once invoked allows the user to set specific parameters corresponding to the desired terrain type. Upon doing so, the algorithms are exercised and the results are displayed in a series of figures identifying the optimum operational angles.Type: GrantFiled: August 25, 2009Date of Patent: June 14, 2011Assignee: The United States of America as respresented by the Secretary of the Army.Inventor: Mark A.
