  • Patent number: 8199020
    Abstract: A temperature-sensitive thermal cutoff fuse RFID tag is provided with a bimorph element and thin conductive bridges positioned on an RFID tag substrate that can react to all changes in storage temperature conditions. The bimorph element is configured and positioned so that when it bends in response to one or more predetermined temperatures, the bimorph element will break one of the conductive bridges and cause an open circuit that can be detected when the RFID tag is interrogated by a sensor. The temperature-sensitive thermal cutoff fuse RFID tag can provide high and low temperature information about numerous stored objects such as food, medicine, chemicals, batteries, explosives and munitions. Multiple temperature conductive bridge cutoff fuse RFID tag arrangements and methods for notifying the user when a required storage temperature has been reached with a passive temperature-sensitive thermal cutoff fuse RFID tag.

  • Patent number: 8149956
    Abstract: 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.

  • Patent number: 8104653
    Abstract: An air breathing battery apparatus is connected to the hollow tubing of a backpack frame to provide an uninterrupted, water-resistant, light-weight power supply during extended remote operations in the field. Air breathing power sources are connected to the hollow tubes of the backpack assembly to provide a constant uninterrupted air supply in a relatively small package that fits easily into the backpack frame with only negligible added weight. The positioning of the air breathing power source in a backpack composed of hollow tubing also protects the battery from inclement weather or when the user is in water, for example, while fording a river or stream, to permit the uninterrupted use of the electronics powered by the battery.

  • Patent number: 8035551
    Abstract: A pulsed compression noise correlation radar uses noise modulation and pulse compression technology to scramble recognizable transmit signal characteristics and reduce transmit energy. The pulsed noise correlation radar advantageously uses pulse compression technology, a pulsed linear frequency modulated noise correlation mixer, and a new and innovative noise fused waveform to automatically correlate the pulsed linear frequency modulated (LFM) noise waveform with the received signal. The pulsed noise correlation radar apparatus and system now make it possible to effectively reduce transmitting power, preserve high band widths through oversampling in the receiver, and achieve multi-channel array frequency diversity. A secure pulsed compression noise correlation radar system and methods for undetected target detection with pulsed noise correlation radar and a pulsed LFM fused noise waveform are also provided.

  • Patent number: 8020432
    Abstract: 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.

The electrically small shortened HF and VHF microstrip cylindrical antennas are constructed with concentric, ceramic cylinders having copper coating that operate at low frequencies. The concentric, ceramic cylinders alternate with concentric copper layers in a corrugated alternating structure where certain copper layers function as the ground plane and others function as part of the radiating patch providing both a shortened antenna length and the ability to operate efficiently at low frequencies. It is now possible to provide a ten-fold size reduction with these antennas.

  • Patent number: 7961138
    Abstract: 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.
