  • Patent number: 11891948
    Abstract: A moving wall positive displacement turbine system, or moving wall engine, utilizes the relative rotation of a ring, a central body, and a housing with respect to each other to generate power, where the ring is concentrically positioned in a channel between the central body and the housing. The housing and central body remain stationary while the ring rotates within the channel. The channel has low friction walls on either side to reduce friction between rotating components. The ring has a series of vanes passing through it and pivotally attached on each side to the low friction walls in the housing to compress an air-fuel mixture prior to combustion. The system is able to compress and combust an air-fuel mixture to generate direct rotational energy.

  • Patent number: 11817173
    Abstract: Systems and methods are provided herein that implement and utilize temporal state machines and other temporal computational/memory circuits. For example, a temporal state machine is provided that comprises a temporal computational unit comprising at least one circuit to perform a time-domain operation, and a temporal memory unit. Both the temporal computational unit and temporal memory unit can operate using solely, or partially, time-encoded wavefronts. The computation unit accesses time-encoded wavefronts from the memory and can output and write time-encoded wavefronts back to the memory.

  • Patent number: 11688599
    Abstract: An environmental sensor may acquire data related to flux and energy of charged particles in an environment for using the data to determine, in substantially real time, whether the environment is conducive to an anomaly caused by the charged particles. The sensor may include an electrostatic analyzer structurally configured for charged particle detection, the electrostatic analyzer generating controllable electric fields to provide energy filtering of incoming charged particles, where, after filtering, the charged particles impact a charge multiplier to establish a detectable signal. The sensor may further include a plurality of silicon detector telescopes structurally configured to collectively detect electrons having energy within the range of about 100 electronvolts (eV) to about 5 mega-electronvolts (MeV) and to collectively detect protons having energy within the range of about 2 MeV to about 100 MeV.
