  • Publication number: 20230128519
    Abstract: An electrical connector for high speed signals. The connector has multiple conductive elements that may serve as signal or ground conductors. A member formed with lossy material and conductive compliant members may be inserted in the connector. The conductive compliant members may be aligned with conductive elements of the connector configured as ground conductors. For a connector configured to carry differential signals, the ground conductors may separate pairs of signal conductors. The member may further include a conductive web, embedded within the lossy material, that interconnects the conductive compliant members. For a receptacle connector, the conductive elements may have mating contact portions aligned along opposing surfaces of a cavity. The conductive elements may have contact tails for attachment to a printed circuit board and intermediate portions connecting the mating contact portions and the contact tails. The conductive compliant members may press against the intermediate portions.

  • Patent number: 11593685
    Abstract: An omnichannel intelligent negotiation assistant for generating timely, contextual negotiation assistance to a negotiator. The invention includes a semantic term extractor for converting a contract document into a negotiable term sheet. An omnichannel listener captures all negotiation inputs associated with a negotiation event, sequences each negotiation input by time, and analyzes the sentiment of the negotiation inputs in the context of a term sheet. The resulting annotated negotiation input stream is processed by an intervention generator that includes models of the parties and the negotiation itself as well as a referent negotiation model. The intervention generator includes a game theoretic model that, in concert with a trade-off matrix, allows the intervention generator to produce timely contextual interventions to the negotiator that assist in achieving a superior resulting negotiated agreement.
