  • Patent number: 10781099
    Abstract: An underwater hydrogen generator can include a watertight reaction housing enclosing a metering chamber. The metering chamber can have an upper portion that terminates at a piston opening, and a lower portion that merges into a funnel, which can further terminate at a metering opening. The metering chamber can be filled with an acid accelerator, and the watertight reaction void can be partially filled with NaBH4 in solution. The generator can further include a seawater float valve that can be in fluid communication between the external environment, the metering chamber and the void defined by the reaction housing. The float valve, metering chamber and reaction housing can cooperate to generate hydrogen when said generator is submerged, by allowing seawater to contact both the acid accelerator and the NaBH4. The size of the metering opening can determine the rate at which acid accelerator is added to the NaBH4 solution.

  • Patent number: 10778451
    Abstract: Disclosed are physical unclonable functions (“PUFs”) that provide both a hardware timestamp and an encryption key. The timestamp is more accurate than traditional timestamps generated by software calls to the computing device's operating system, while the encryption key can be used for, among other things, securing time-synchronization packets sent across a network. By combining timestamp generation with encryption key generation, the PUFs provide enhanced security while being cheaper to build and to operate than the specialized cryptographic hardware that they replace.

  • Patent number: 10775459
    Abstract: The invention relates to compounds known as “optorelaxers,” for example, spin crossover (SCO) complexes that exhibit light-induced excited state spin trapping (LIESST) effects with transient unpaired electron spins, which are created (or destroyed) by varying the level and/or wavelength of light to which the complexes are exposed. Light conditions are used to switch the optorelaxers between transient paramagnetic and diamagnetic states to provide real-time control of T1 relaxation in nuclear magnetic resonance (NMR) spectroscopy methods. The optorelaxers and methods of the invention provide increased detection sensitivity of NMR spectroscopy, with increased structural information content, while maintaining resolution for a wide variety of different NMR-active nuclei.

  • Patent number: 10763906
    Abstract: A system and method are disclosed for selecting a sampling frequency in a system that performs bandpass sampling and uses a polyphase downconverter channelizer to receive multiple RF signals. The method accounts for the frequency location of the received signals throughout the signal reception process to simplify the overall processing. The procedure finds a sampling frequency that positions all or a subset of the sampled signals such that the sampled signals fall within the input channels of the polyphase downconverter channelizer, thus simplifying processing compared to prior art methods which address the bandpass sampling and polyphase downconverter channelizer components separately.
