  • Patent number: 11522192
    Abstract: The invention discloses a zinc organic battery having a container. The container contains a positive electrode active material, a positive electrode current collector, an organic solvent, a zinc negative electrode, and an aqueous electrolyte. The organic solvent and the aqueous electrolyte are not miscible and are layered due to different densities. The positive electrode active material has a redox activity, and has the two forms of an oxidized state and a reduced state. If the positive electrode active material itself is a liquid and is difficult to be dissolved in the aqueous electrolyte, then the organic solvent may be omitted. The positive electrode active material itself doubles as the organic solvent and is layered with the aqueous electrolyte. The zinc negative electrode is immersed in the aqueous electrolyte and is not in contact with the organic solvent. The aqueous electrolyte is an aqueous solution containing a zinc salt.

  • Patent number: 7693211
    Abstract: Fast Fourier Transform (FFT) based Phase Lock Loops (PLLs) are provided for use in navigational signal receivers. In an embodiment, a navigation receiver correlates a received navigational signal with a locally generated signal into correlation samples, e.g., one-millisecond correlation samples. The navigation receiver includes a FFT based PLL that corrects phase shifts in the correlation samples due to the Doppler frequency by considering both the Doppler frequency and its rate of change, which are obtained from a FFT computation with interpolation. The phase corrected correlation samples are then integrated over a length of a navigation data bit, e.g., 20 milliseconds, to determine the sign of the data bit of the received signal. In another embodiment, a soft decision feedback technique involving integration extending over the present data bit and several prior data bits is used to determine the sign of a present data bit of the received signal.

  • Patent number: 7477189
    Abstract: Provided herein are systems and methods for achieving long coherent integration in a navigational receiver to improve the sensitivity of the receiver and enable the receiver to acquire, reacquire and track signals under very weak signal conditions. In an embodiment, phase compensation is computed based on estimated Doppler frequency, rate of change of the Doppler frequency with time, and second order rate of change of the Doppler frequency. The Doppler frequency may be computed from an orbital model or ephemeris. This phase compensation is used to compensate samples of the input signal for changes in the phase due to the Doppler frequency. Frequency components of the phase-compensated samples are then computed using a frequency analysis such as a Fast Fourier Transform (FFT). The maximum frequency component is taken as an error frequency and used to compensate the samples of the input signal for residual frequency error.

  • Patent number: 6887144
    Abstract: An element-doped diamond crystal is disclosed herein. The crystal includes at least one dopant element which has a greater concentration toward or near an outermost surface of the crystal than in the center of the crystal. The concentration of the dopant element is at a local minimum at least about 5 micrometers below the surface. The concentration-profile of the dopant element for these diamond crystals causes an expansion of the diamond lattice, thereby generating tangential compressive stresses at the surface of the diamond crystal. These stresses beneficially increase the compressive fracture strength of the diamond.

This mixture is subjected to diamond-formed high pressure/high temperature (HP/HT) conditions for a time adequate for forming diamond. The thus-formed diamond product is recovered to contain boron substituted into the diamond structure. The fully dense core is substantially devoid of nitrogen (N) content, which mostly comes from air. Thus, the fully dense core is substantially devoid of air. The preferred source of B is amorphous B; although other sources of B can be used to form the boron-doped, blue diamond of the present invention.
