  • Publication number: 20240116609
    Abstract: A life boat is disclosed having a hull, a propulsion system, and a conning system. The hull has an open or openable bow, a fore deck and a powered recovery ramp installed in or on the fore deck for deployment forwards of the bow for recovery of a casualty ahead of the bow of the life boat. The life boat may be unmanned and able to draw a survivor up on the recovery ramp and into the relative safety of the rescue deck area of the fore deck without human assistance. The life boat 1 may include a cabin area where the survivor can be given more protection from the environment.

  • Patent number: 10054680
    Abstract: A radar signal target detection and display system employs feedback to produce improved detection and tracking. Portions of the radar images for each antenna channel to search for the target of interest are defined using the track state to define the center of the search region and using the track covariance matrix to define the size of the region. Moving reference processing (MRP) is performed. MRP employs a search centered on the motion state derived from the detection sent to the tracker on the previous coherent processing interval (CPI). Space-time adaptive processing (STAP) is employed on each CPI using a unique set of adaptive degrees of freedom (DOFs) derived from pre-MRP and post-MRP complex radar image amplitudes for each antenna channel.

  • Patent number: 9821143
    Abstract: An MR compatible steerable sheath with elastomeric member is provided. The elastomeric member is configured to serve as a reservoir and receive contrast media therewithin. The elastomeric member is positioned on the distal end of the steerable sheath and may circumferentially surround the sheath shaft or be offset from a longitudinal axis thereof. In operation, the contrast media allows a user to view the distal tip of the steerable sheath by virtue of the contrast media contained within the elastomeric member.

  • Publication number: 20160008575
    Abstract: An MR compatible steerable sheath with a slidable valve adaptor is provided. The slidable valve adaptor is configured to maintain the steerable shaft in a proximal position such that there is slack in first and second longitudinal movement wires when the valve adaptor is in a first position, and is configured to remove slack from the first and second longitudinal movement wires when the valve adaptor is slidably moved to the second position. Slidable valve adaptor also optionally includes a safety cap that prevents insertion of a catheter into the control handle until the valve adaptor is in the distal position.

  • Patent number: 8501468
    Abstract: A versatile compartmentalized cell culture device, with a selectively permeable membrane separating the compartments, provides many attributes relative to traditional devices. It can be configured for high-density cell culture, co-culture, and sample dialysis while rolling or standing still. It can also be configured for continuous movement of liquid between compartments. The wide combination of attributes not found in other membrane based cell culture and bioprocessing devices includes more cell capacity, more cell secreted product capacity, higher cell and product density, increased medium capacity, minimized use of exogenous growth factors, compatibility with standard cell culture equipment and protocols, increased scale up efficiency, capacity to function when rolling or standing still, capacity for perfusion without the need for pumps, and more efficient sample dialysis.
