  • Publication number: 20220155331
    Abstract: A method of facilitating controlled particle deposition from a droplet dispenser involves receiving at least one pre-dispensed image of a dispensing portion of the droplet dispenser, the dispensing portion including fluid to be dispensed in a subject droplet to a subject target region, receiving at least one post-dispensed image of the dispensing portion of the droplet dispenser after the subject droplet has been dispensed, comparing the at least one pre-dispensed image and the at least one post-dispensed image to determine a subject droplet particle count representing a count of particles included in the subject droplet, and producing signals for associating a representation of the subject droplet particle count with the subject target region. Other methods, apparatuses, systems, and non-transitory computer readable media are disclosed.

  • Patent number: 10694315
    Abstract: The present invention relates to a technique for allowing registered mobile users of the same or different social networks in the vicinity to use mobile devices of the same or different operation system to identify each other and exchange business information. Each registered mobile user discovers other registered mobile users in the proximity location through their mobile devices. A central server is configured to allow communication between a plurality of registered mobile users with connection through internet and to facilitate business information exchange between different mobile users. The central server manages introduction and connection of a plurality of registered mobile users by positive identification of registered mobile users, and associates unique identification of mobile user devices through Internet and returns identities of other mobile users in the vicinity or in proximity thereto, bringing an image of a human face along with names and business attributes to a device allocation.

  • Patent number: 10017263
    Abstract: An impact mitigation system for an aircraft and method of deploying the impact mitigation system is disclosed. A state parameter of the aircraft is obtained. The state parameter is used with an aircraft performance model to determine an acceleration capability of the aircraft. A trajectory of the aircraft is predicted using the state parameter of the aircraft and the acceleration capability of the aircraft. A location of an object with respect to the aircraft is determined and the impact mitigation system is deployed when the predicted trajectory indicates a contact with the object at a predicted contact velocity higher than a threshold velocity at a future time.

  • Patent number: 6334951
    Abstract: A reverse osmosis water treatment system includes a tube connecting unit 10 having a water incoming end 102, a water outgoing end 103, and a diaphragm 104 having a check valve 108 therein to allow water to flow directly from the incoming end to the outgoing end. In operation, water flows from the tube connecting unit through-hole 105 and into preliminary filtering units 2 and membrane unit 3 via the pipe assembly 1. Wastewater from the membrane unit drain end 31 is then routed back to the tube connecting unit via pipe assembly 42 and through-hole 106. A faucet 5 is provided at the water outgoing end to deliver water for non-drinking uses. By virtue of issuing water from the outgoing end, the membrane is washed and cleaned. Accordingly, the amount of discharged wastewater is greatly reduced so that water resources are conserved and the useful life of the membrane is prolonged.
