Patent number: 12153034Abstract: A carbon monoxide detecting electrical receptacle assembly for alerting a user to dangerous levels of carbon monoxide includes a housing that is attachable to an electrical box. A socket in a front face of the housing allows for insertion of a corresponding plug. A set of connectors attached to electrical wiring operationally engages the socket, a sensor, a notification module, and an indicator light to an electrical circuit. The sensor measures a level of carbon monoxide in air proximate to the housing. The notification module notifies a user when the level of carbon monoxide reaches a preset value. The indicator light selectively emits a first color of light and a second color of light when the level of carbon dioxide is below and equal to or greater than the preset value, respectively.Type: GrantFiled: April 11, 2023Date of Patent: November 26, 2024Inventor: John Cote

Patent number: 6669554Abstract: A hidden ventilating sill plate is fundamentally a new building product, installed along the top surface of the exterior perimeter foundation. It replaces the existing wood sill plate. The invention has a continuous set of air slot channels of a proscribed size perpendicular to the longitudinal axis, along its base, communicating natural air flow from the exterior to the interior of the crawlspace. The exterior side of the slot channels can open earthwards to allow the venting to be completely hidden from view, when the sill member extends out beyond the exterior face of the foundation and wall. The vent concealment feature also functions as a base to the siding and an integral drip edge. Insect mitigation is achieve by adding a mesh screen over the exterior exposed slotted openings. The preferred material for this invention is a plastic-fiber composite, allowing rot resistance, shear capabilities and, rapid extrusion or molding of the sill profile.Type: GrantFiled: August 26, 2002Date of Patent: December 30, 2003Inventor: John Tregidga
