  • Method and cavity for suppression of cavity flow oscillations and acoustic loads using curved rear face
    Patent number: 10823207
    Abstract: Pressure oscillations or acoustic loads over an open type cavity having a front face an upper edge of which constitutes a leading edge and having a rear face an upper edge of which constitutes a trailing edge are reduced by applying curvature to the rear face so as to present a convex curved surface internal to the cavity. In one embodiment, a cross-section through a longitudinal axis of the convex curved surface describes part of an ellipse.

  • AUTOMATED NEGOTIATOR GOVERNED BY DATA SCIENCE
    Publication number: 20190019148
    Abstract: A system, method and device for enabling improved negotiations in a supply chain between parties to the supply chain is disclosed. The system, method and device includes a communication device for receiving interactions and transactions regarding the parties involved in the supply chain, a processor for determining factors that aid in the leverage of negotiations between the parties involved in the supply chain by analyzing the received interactions and transaction, and a transmitter for transmitting the identification of the determined factors and the respective values based on the entity using the device.

  • Dissolution testing of solid dosage forms intended to be administered in the oral cavity
    Publication number: 20060288805
    Abstract: The invention is a method and device for determining dissolution of a solid compound within the oral cavity. The device models dissolution within the oral cavity with a flow-through cell containing a solid compound and physiological amounts of simulated saliva. The device supplies and removes the simulated saliva at rates similar to production and loss of saliva within the oral cavity. The simulated saliva interaction with the solid compound mimics saliva interaction with a solid compound within the oral cavity. Dissolution of solid compound is determined from simulated saliva collected from the flow-through cell outflow.
