  • Patent number: 11509580
    Abstract: Source routing techniques include sending data across several networks, while limiting source routing overhead. For example, the source routing techniques may use a first address format to route data to nodes along a routing path that are within a first network where a source node is located, and use a second address format to route the data to a node along the routing path that is within a second, different network. The node in the second network may similarly route the data through the second network using the first address format for nodes within the second network and, if needed, route the data to a node within a third network using the second address format. This may be repeated for any number of networks to reach a destination.

  • Publication number: 20220313431
    Abstract: A heart valve prosthesis is provided having a self-expanding multi-level frame that supports a valve body comprising a skirt and plurality of coapting leaflets. The frame transitions between a contracted delivery configuration that enables percutaneous transluminal delivery, and an expanded deployed configuration having an asymmetric hourglass shape. The valve body skirt and leaflets are constructed so that the center of coaptation may be selected to reduce horizontal forces applied to the commissures of the valve, and to efficiently distribute and transmit forces along the leaflets and to the frame. Alternatively, the valve body may be used as a surgically implantable replacement valve prosthesis.

  • Publication number: 20220296949
    Abstract: The present invention relates to a carbon-based material for use in a piece of personal protective equipment and an air filtration system. The carbon-based material may function as a filter by providing a tortuous path for a pathogen to traverse. The carbon-based material may be used as a carbon-based heater that can reach a pathogen inactivation threshold temperature to enable heat inactivation of one or more pathogens. In embodiments where a piece of personal protective equipment includes a carbon-based heater, an insulating layer may be included to attenuate the temperature generated by the carbon-based heater from the face of a user.

  • Patent number: 11394202
    Abstract: Methods and apparatus can be used to turn an existing 240 VAC or 480 VAC/600 VAC outlet into two or more time-sharing, i.e., one operating at a time, outlets. An AC switch box with two time-sharing outlets can be made with either a mechanical switch for switching which load receives power, or automatically, by a microcomputer system, for example. In the automatic AC switch box, the non-favored outlet may be typically powered on unless a load is detected at the favored/default outlet, when power to the non-favored outlet is automatically disconnected until the load is reduced or eliminated.

  • Patent number: 11364901
    Abstract: A driving support apparatus according to the invention estimates the position of a moving body by controlling a position estimation unit when the tracking-target moving body leaves a first area or a second area to enter a blind spot area and detects the position of the moving body by controlling a position detection unit when the moving body leaves the blind spot area to enter the first area or the second area. In this manner, the trajectory of the tracking-target moving body is calculated so that the trajectory of the moving body detected in the first area or the second area and the trajectory of the moving body estimated in the blind spot area are continuous to each other and driving support is executed based on the calculated trajectory of the tracking-target moving body.
