Patent number: 8674271Abstract: A breathable electrical heater element for a topical application device such as a wound dressing or a therapeutic heating pad is disclosed. The heater element is formed by photochemically etching a track pattern onto a porous metallised fabric (e.g. nickel coated woven polyester). The heater element has a skin or wound contact layer laminated to the front face of the heater element. An adhesive layer is laminated to the back face of the heater element. The adhesive layer forms an overhang to provide an adhesive border around the wound contact layer to adhere the device to the skin of a patient. Therapeutically active drugs (optionally microencapsulated) may be incorporated into the skin or wound contact layer. Operation of the heater element causes the skin or wound contact layer to release the active drugs to the skin or wound of the patient. Appropriate control of the temperature of the heater element allows control of the release of the active drugs.Type: GrantFiled: June 21, 2010Date of Patent: March 18, 2014Assignee: NEL Technologies LimitedInventor: Patrick Ferguson

Patent number: 8258725Abstract: A klystron has a hollow beam electron gun that has a circular planar electron emitting surface. A hollow electron beam is directed from the electron gun through a plurality of drift tubes, resonant chambers and magnetic fields to a collector. The hollow electron beam does not experience significant radial movement and can operate at a lower beam voltage which reduces the required length of the RF interaction circuit and lowers the risks of RF arcing.Type: GrantFiled: April 3, 2008Date of Patent: September 4, 2012Inventor: Patrick Ferguson

Patent number: 7563341Abstract: The present invention relates to a method for thermally printing a pre-selected dye image (45) onto a three dimensional object (16). The method involves placing an image carrier sheet (24) containing a pre-selected dye image (45) over the object (16). A flexible membrane (26) is lowered over the object (16) and the image carrier sheet (24). A vacuum is established under the membrane (26) causing the image carrier sheet (24) to conform to the shape of the object (16). The membrane (26) or image carrier sheet (24) carry flexible heating elements (36), which are heated, to thermally transfer the dye image (45) onto the object (16). The flexible heating elements (36) can be made by etching an electrical circuit in a metal foil (34) which is bonded to a film substrate (30).Type: GrantFiled: June 25, 2004Date of Patent: July 21, 2009Assignee: Key-Tech, Inc.Inventors: Patrick Ferguson, Paul Geoffrey Newton, Kenneth Neri
