  • Publication number: 20240398309
    Abstract: An electronic device for long-term adhesion to a mammal includes a housing with an electronic component. The electronic device may include a first wing and a second wing, each being integrally formed with the housing. An electrode is positioned on a bottom surface of each of the wings, the electrodes electrically connected to the electronic component. An adhesive layer is provided for adhesion to a surface of the mammal. The adhesive layer may cover a portion of the bottom surfaces of the wings but generally does not cover the electrode or a bottom surface of the housing. A method of applying an electronic device to a mammal includes removing first and second adhesive covers from first and second wings of the electronic device to expose an electrode and an adhesive coated on a bottom surface of each wing.

  • Patent number: 5233823
    Abstract: A high efficiency/low nitric oxide emission gas turbine engine includes an interchanger for cooling a compressed air side stream which is used for cooling the turbine section. The heated fuel is then mixed with steam for injection into a combustor, thereby reducing nitric oxide emissions, while preventing condensation during mixing. Where water is used for injection instead of steam, both the fuel and water are preheated by interchange with the hot compressed gas stream. Preheating the fuel and/or water prevents steam condensate or water from entering the combustor, and does so using heat available within the gas turbine cycle thereby increasing overall turbine efficiency. In addition, utilizing a fuel/air interchanger reduces the size of the heat exchanger and the need for other auxiliary equipment, reducing costs while increasing turbine efficiency.

  • Patent number: 4231120
    Abstract: The securement of an endoprosthetic orthopaedic member of plastics material in cancellous bone involves the provision of a relieved configuration on the member, the upstanding elements of such configuration flexing to afford an interference fit upon translation of the member into a substantially complementary, but slightly undersized recess in the bone. The member is suitably of stem or other elongated form with an annular or helical finned configuration as the upstanding elements. Preferably each such fin configuration includes a sequence of longitudinally separated fins individually extending over a minor circumferential portion of the member. The member will commonly be formed as a one-piece projection from a prosthetic bone joint component.

  • Patent number: 4135505
    Abstract: This invention concerns variably connectable orthopaedic fracture fixing apparatus of a kind comprising at least one elongate member, at least two universal joint assemblies for coupling said member and associated bone pins, and an adjustment assembly for adjusting the spacing between said joint assemblies when connected with said member. In the present case the joint assemblies are each of ball joint form in which a ball is clamped by a wedge action between two sockets. Also, the adjustment assemblies are not necessarily integrated with a fracture fixing network constructed with the apparatus, but are separable therefrom. In addition, the joint assemblies can receive bone pins in a variety of closely spaced positions to minimize any need to stress the pins.
