  • Publication number: 20210067247
    Abstract: A dynamic free-space-optical femto-cell (DFF) communication system is disclosed. The system operates to allow bi-directional communication between transceiver and receivers using free space optics and line of sight alignment and tracking. The system dynamically adjusts beam direction and beam shape in order to maximize power efficiency and maintain line of sight using beam steering and beam forming. The result is greatly reduced power requirement, improved security and dynamic mobility.

  • Patent number: 10718258
    Abstract: A direct-injection stratified charge internal combustion engine includes a combustion cylinder to receive an air-fuel mixture, and an air intake port to inlet air into the combustion cylinder. The direct-injection engine also includes a fuel injector configured to deliver fuel within the cylinder in a spray pattern substantially aligned to a cylinder central axis to create the air-fuel mixture. A spark igniter is located within a path of the spray pattern to ignite combustion of the air-fuel mixture. The direct-injection engine further includes a movable piston defining a lower boundary of the combustion cylinder to contain the combustion of the air-fuel mixture. The piston is configured to include a bowl portion having local geometric features located on an intake port side of the combustion cylinder to redirect fluid flow towards a vortex in fluid communication with a combustion location near the cylinder central axis.

  • Patent number: 10247770
    Abstract: Various embodiments of a gate oxide breakdown detection technique detect gate oxide degradation due to stress on a per part basis without destroying functional circuits for an intended application. Stress on the gate oxide may be applied while nominal drain currents flow through a device, thereby stressing the device under conditions similar to actual operating conditions. The technique is relatively fast and does not require analog amplifiers or tuning of substantial amounts of other additional circuitry as compared to conventional gate oxide breakdown detection techniques.
