  • Patent number: 12151036
    Abstract: An electrification system is used to prevent the transmission of pathogens by dermal contact. The electrification system includes a skin-bracing object, a power supply, and at least one resistor. The skin-bracing object includes an object body and a conductive feature. The skin-bracing object is an object that regularly comes into physical contact with a user's skin. The object body is the structure of the skin-bracing object and can be, but is not limited to, a pillowcase, a bed sheet, a bed pad, a blanket, a piece of medical gauze, a face mask, a set of medical scrubs, or a food preparation surface. The power supply, the resistor, and the conductive feature are electrically connected in series to each other. Thus, the conductive feature carrier an electrical current to electrify pathogens that come into physical contact with the conductive feature.

  • Patent number: 12034536
    Abstract: A method of communicating between nodes in a network where a node receives a sequence of symbols that will form a packet on a first communications channel and has a planned packet that it would send on a second communications channel. A destination is encoded into an arbitration portion of a header sequence of the packet, the header sequence comprising a sequence of symbols. The transmission on the second communications channel is as per the planned packet, for as long as the symbols of the planned packet match the symbols being received on the first channel. An arbitration decision is made when the symbols do not match, with the node either continuing to send the rest of the planned packet, or the rest of the packet being received on the first communications channel.

  • Patent number: 10135362
    Abstract: Described is a method for converting power including controlling operation of a plurality of series connected modules including a DC power sources and storage devices such that the total voltage across the series connected modules includes an AC signal. A storage parameter is defined based on a sum of a function of the voltages in the storage devices in the modules and one or more voltage control levels are defined for each of or a plurality of the storage devices. An average current drawn from the series connected modules over a time period is set such that the storage parameter approaches a target value. The target value is decreased for a subsequent time period in the event that none the voltage control levels are reached and increased in the event that one or more of the voltage control levels are reached.
