  • Publication number: 20210395916
    Abstract: A method of fabricating synthetic diamond material using a microwave plasma activated chemical vapour deposition technique is provided which utilizes high and uniform microwave power densities applied over large areas and for extended periods of time. Products fabricated using such a synthesis technique are described including a single crystal CVD diamond layer which has a large area and a low nitrogen concentration, and a high purity, fast growth rate single crystal CVD diamond material.

  • Patent number: 10883194
    Abstract: A single crystal CVD diamond component comprising: a surface, wherein at least a portion of said surface is formed of as-grown growth face single crystal CVD diamond material which has not been polished or etched and which has a surface roughness Ra of no more than 100 nm; and a layer of NV? defects, said layer of NV? defects being disposed within 1 ?m of the surface, said layer of NV? defects having a thickness of no more than 500 nm, and said layer of NV? defects having a concentration of NV? defects of at least 105 NV?/cm2.
    Type: Grant

  • Publication number: 20200118656
    Abstract: A method for validating healthcare transactions via a web-based platform includes: obtaining a preliminary diagnosis from a remote computing device; comparing the preliminary diagnosis to a predetermined diagnosis criteria; determining whether the preliminary diagnosis satisfies the predetermined diagnosis criteria; authorizing payment to a predetermined entity when the preliminary diagnosis is determined to satisfy the predetermined diagnosis; generating a unique token when payment is authorized; recording a transaction in a distributed ledger based on the unique token to establish a recorded transaction; associating the unique token with the recorded transaction; obtaining a fulfillment request from the remote computing device; validating the recorded transaction based on the unique token to establish a validation; and transmitting an indication to fulfill the fulfillment request based on the validation to the remote computing device.
