  • Publication number: 20240109655
    Abstract: The present invention comprises a system which includes a novel quick release thruster mount system using one or more removable elements allowing the thrusters to be removed quickly. The present invention also comprises a novel “float compartment centric” design where no wiring to the cockpit is necessary. Redundant power units are self-contained and protected. The novel design incorporates thrust force over the surface of the water rudders improving directional control. The rudder anti lift device ALPB allows the rudders to remain in the water while reverse or braking thrust is applied. Control and monitoring are done wirelessly from the safety of the cockpit reducing hazard while maneuvering to avoid prop strike hazards to pilot, persons or objects. The system offers the ability to maintain positive directional control while taxing downwind resisting the inherent weathervane forces, braking, and turning maneuvers unachievable with current methods.

  • Patent number: 11920120
    Abstract: Provided herein are isolation processes and the associated hardware to allow fluid streams to be isolated from a sterilized system (e.g., a sterile process vessel) that contains a sterile process. The isolation processes described herein allow for continuous removal of fluid streams (e.g., waste streams, liquid containing recombinant therapeutic proteins) from a sterilized system (e.g., a biological manufacturing system), which provides for less manual manipulation of the sterilized system and a decreased risk of contaminating the sterilized system.

The stimulating includes increasing the current level of each pulse in the sequence of pulses from an immediately preceding pulse by a first current increment. The method includes determining that a first evocation pulse from the sequence of pulses evokes a first muscular response. The method includes stimulating the tissue with a second evocation pulse from the sequence of pulses to evoke a second muscular response. The stimulating includes decreasing the frequency of the delivery of each pulse in the sequence of pulses and increasing the current level of each pulse in the sequence of pulses from the immediately preceding pulse by a second current increment.
