Graeme Ramsay Mitchell 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: 10317382
    Abstract: Packaging for electronic components includes provisions to short selected electrodes of the components together. A plastic base portion with a plurality of component receiving cavities carries a flexible, carbonized shorting element which extends between cavities. The cavities include a recess which is adjacent to the shorting element. Components can be inserted into respective cavities, and some of the electrodes will contact the shorting element. Other electrodes will extend into the recess and not be shorted.
    Type: Grant
    Filed: December 9, 2014
    Date of Patent: June 11, 2019
    Assignee: Life Safety Distribution AG

  • Patent number: 8888978
    Abstract: An electrochemical oxygen sensor is provided. The electrochemical sensor includes a housing having first and second compartments, a sensing electrode disposed within the first compartment of the housing, a consumable anode disposed within the second compartment of the housing, a porous separator between the sensing electrode and consumable electrode that separates the first and second compartments and an electrolyte saturating the porous separator and consumable anode. A first aperture on a first end of the housing extends between an outside surface of the housing and first compartment that allows gas access to the sensing electrode. A venting system on a second, opposing end of the housing includes a second aperture extending between the outside surface of the housing and second compartment and has a predetermined permeability that controls pressure in the second compartment and loss of moisture from the sensor.
