Patents by Inventor Patrick Calhoun

Patrick Calhoun 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: 10964955
    Abstract: Methods and systems for providing battery backup power to a home or other building are disclosed. Methods and systems include a fluid container holding an electrolyte solution. The electrolyte solution is prevented from flowing through an array of galvanic cells having annular flow paths via a fluid flow control mechanism, such as a valve, which is energized by an external power source. When the external power source is removed, such as during a power outage, the fluid flow control mechanism is deenergized and electrolyte solution is allowed to flow through the galvanic cell array, generating electric current. Energy produced by the system then powers the home or other building until the external power source returns, which in turn closes the fluid flow control mechanism and ceases energy production by the system.

  • Patent number: 6157649
    Abstract: A method for coordinating and controlling multiple data streams representing a data transmission session that terminate in different termination units (such as network access servers) using a virtual data stream tunnel is presented. The data streams are transmitted over two or more links, collectively forming a "bundle. One of the termination units that receives a data stream is designated as the termination unit to receive and reconstruct a call. The designated termination unit is the "owner" of the bundle. A termination unit that is a not a bundle owner creates a virtual tunnel to the termination unit that is the bundle owner, and sends data streams through the virtual tunnel to the bundle owner to reconstruct the call. The designated termination unit reconstructs the data streams for the bundle and directs the bundle to a destination.
