  • Patent number: 11192184
    Abstract: The present disclosure is directed to systems and methods for producing a metal-containing powder useful for additive manufacturing. The metal-containing powder includes a plurality of metal-containing platelets having a defined physical geometry and a defined aspect ratio. The metal platelets may be produced by depositing a metal layer on a substrate that includes one or more recessed or raised surface features. The one or more recessed or raised surface features create a fracture pattern in a metal layer deposited across at least a portion of the one or more surface features. By separating the metal layer from the substrate and fracturing the metal layer along the fracture pattern, a plurality of metal platelets are produced. In some embodiments, a release agent may be disposed between the metal layer and the substrate to facilitate the separation of the metal layer from the substrate.

  • Publication number: 20210355420
    Abstract: Described herein is a beads-free bioprocessor as an automated and cost-effective T cell processing and manufacturing platform. T cells are a core component in CAR T cell therapies for cancer treatment, but are difficult to manufacture to scale in clinically relevant quantities. The 3D bioprocessor provides an alternative device that is scalable, beads-free, easy-to-use, and cost-effective for using CAR T cell therapy in cancer immunotherapy. Besides CAR T cell application, this platform technology has potential for many other applications such as cancer cell isolation.

  • Patent number: 11169104
    Abstract: A system for simulating the effects of use and aging on immersive coolants. Two conductive coils are immersed in a tank containing a sample of the coolant. The coils are spaced such that electrical activation of the first coil induces current in the second coil. A DC power source is provided to an inverter, which provides AC current for activating the first coil. The induced AC current in the second coil is delivered to a rectifier which converts the induced AC current to DC current. The DC current is then returned to the power source. The electromagnetic field between the coils simulates motor operation, so that the coolant's physical and chemical characteristics can be tested for the effects of use and aging.

  • Patent number: 11165492
    Abstract: The present disclosure is generally directed to an approach for spatializing audio from a received radio transmission to allow a radio operator to audibly perceive audio from the received radio transmission as if originating from a direction that corresponds to a physical location of the transmitting radio. On the receiving side, also referred to herein as a receive (RX) pipeline, a radio device configured consistent with the present disclosure includes utilizing an orientation tracker, and head related transform functions to generate a binaural representation of an incoming transmission such that audio associated with the same gets spatialized to sound as if coming from a direction corresponding to the transmitting radio. On the transmit side, also referred to herein as the transmit (TX) pipeline, includes utilizing a location sensor (e.g., a time of flight and/or GPS sensor) and encoding scheme such that radio transmissions include associated geographical location data.

  • Patent number: 11156181
    Abstract: A method of operating a hydrogen-fueled internal combustion engine. The engine is determined to have a mode control value, which represents a threshold torque. During operation of the engine, a demanded torque of the internal combustion engine is determined and compared to the threshold torque. If the demanded torque is less than the threshold torque, the engine is operated in a low load mode that uses spark ignition and pre-mixed combustion. If the demanded torque is greater than the threshold torque, the engine is operated in a high load mode that uses compression ignition and diffusion combustion.

  • Patent number: 11156191
    Abstract: An internal combustion engine having two “banks” of cylinders, the “banks” being defined by cross-connection to different turbochargers. The exhaust from one bank of cylinders goes to a first turbocharger, and the exhaust from the other bank of cylinders goes to a second turbocharger. However, the compressed air delivered from the turbochargers is cross-connected to the cylinder banks. This allows a cylinder bank to be boosted with a turbocharger whose compressed air output does not necessarily match the exhaust energy of that cylinder bank.

  • Patent number: 11125723
    Abstract: A method of testing the residual stress around a cold-worked hole in a test material. The test uses two identical eddy current coil pairs, each pair having a driving coil and a pickup coil. One coil pair is placed into the cold-worked hole. The other coil pair is placed into a non-cold worked hole in a reference material. When the coils are activated, and with a properly chosen phase difference between the excitation signal and the output signal, the in-phase component of the output voltage signal can be correlated to residual stress around the cold-worked hole.

  • Patent number: 11079493
    Abstract: A system and method for testing the integrity of signals incoming to a satellite navigation system. The method is implemented with an array of antenna elements, and a receiver connected to each antenna element. The receivers simultaneously and continuously make measurements on all tracked signals. Each receiver measures the carrier phase of an incoming signal. Based on the carrier phase differences between antenna elements and the distance between them, the azimuth and elevation of the signal source can be calculated. This measured angle of arrival can then be compared to an expected angle of arrival to determine if the signal source is legitimate. The system and method can be also applied to determining the angle of arrival of sources of interference, and to mitigating the effects of both illegitimate and interfering signals.

  • Patent number: 11047967
    Abstract: A method of operating a vertical incidence sounder. The sounder transmits a random modulated sounder signal, and receives a return signal, comprising a directwave component and a reflected component. A first cross-ambiguity process between the transmitted signal and the return signal is used to time and frequency align the return signal with the transmitted signal. The direct wave signal is removed, thereby producing a processed return signal. A second cross-ambiguity process between the transmitted signal and the processed return signal is performed to determine a time offset, which is used to estimate an ionospheric height.
