Patents by Inventor David Sunshine

David Sunshine has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11247922
    Abstract: A water treatment device and methods of treating water such as cooling tower water, swimming pool water, and hot tub or spa water, are described. The water treatment device utilizes ultraviolet radiation, a magnetic field, and ozone fortified air to treat the water, typically resulting in reduced microbial contamination and reduced alkalinity in cooling tower water. Cooling tower water may consequently be run at higher cycles of concentration while reducing or eliminating deposition of minerals on cooling tower components. Swimming pool water and hot tub water treated with the water treatment device typically requires less chlorine, and chlorine levels are typically more stable than without the device.

  • Patent number: 10708042
    Abstract: Systems and methods of the present disclosure include receiving an electronic request to exchange data items. A digital asset associated with the exchange of the data items is generated including a vault unique identifier, and an asset owner. An exchange block is generated on an exchange chain to record the electronic request. An asset copy is generated on the exchange ledger chain to record a non-permissioned copy of the digital asset independent from the vault unique identifier. An asset block is generated on an asset ledger chain to record an authoritative copy of the digital asset associated with the exchange of the data items on the exchange chain; where the asset block header includes an asset block hash concatenated with the vault unique identifier associated with the digital asset. The authoritative copy of the digital asset associated with the electronic request is displayed in response to a user selection.
