  • Publication number: 20220055888
    Abstract: A system for filling a tank for a firefighting helicopter with water without ground personnel, comprising a pilot controlled valve assembly to selectively permit water to flow into the refill tank upon the receipt of a communication transmitted by a communication device within the helicopter. The pilot controlled valve assembly can include a supply valve configured to move between at least a closed state and an open state, a controller configured to control the supply valve, and a receiver configured to send a signal to a controller to cause the controller to at least open the supply valve upon receipt by the receiver of a communication meeting one or more predetermined criteria. The water tank can be filled from a water source, including a municipal water source, when the supply valve is open to provide a more efficient, semi-autonomous refill tank system greatly improves costly and time-consuming manually refill systems.

  • Publication number: 20220054187
    Abstract: Methods for minimally invasive electro-surgical systems are disclosed. One method includes determining if an input device is selected at a control console. If the input device is selected then, providing feedback to a user of the selection of the input device, delaying a first predetermined period of time for the user to receive the feedback, determining if the input device is deselected, and if not deselected, then activating an electrosurgical device to couple energy to tissue. If deselected, the method skips activation of the electrosurgical device. While active, a method includes determining if the input device is deselected, and if so, then deactivating the electrosurgical device, determining if the input device is reselected and if the input device is not reselected, then waiting and determining if a second predetermined period of time has lapsed prior to reselection of the input device and if not, then repeating the reselected determining step.

  • Publication number: 20220056087
    Abstract: The current invention involves a series of fully recombinant multimerized forms of immunoglobulin Fc which thereby present polyvalent immunoglobulin Fc to immune cell receptors. The fusion proteins exist as both homodimeric and highly ordered multimeric fractions, termed stradomers. In comparison to the homodimeric fraction, purified multimeric stradomers have higher affinity and avidity for Fc?Rs with slower dissociation and are useful in the treatment and prevention of disease. The current invention demonstrates that directly linking IgG1 Fc regions to multimerization domains leads to enhanced multimerization and biological activity.

  • Publication number: 20220061046
    Abstract: Embodiments herein include a method in a user equipment (UE) for transmitting uplink control information in time slots of a subframe over a radio channel to a radio base station. The uplink control information is comprised in a block of bits. The UE maps the block of bits to a sequence of complex valued modulation symbols. The UE block spreads the sequence across Discrete Fourier Transform Spread-Orthogonal Frequency Division Multiplexing (DFTS-OFDM) symbols. This is performed by applying a spreading sequence to the sequence of complex valued modulation symbols, to achieve a block spread sequence of complex valued modulation symbols. The UE further transforms the block-spread sequence, per DFTS-OFDM symbol. This is performed by applying a matrix that depends on a DFTS-OFDM symbol index and/or slot index to the block-spread sequence. The UE also transmits the block spread sequence, as transformed, over the radio channel to the radio base station.
