Abstract: Aspects of the subject technology relate to a removable shelter that electrically and/or communicatively integrates with an electric vehicle when the removable shelter is mounted to the vehicle. The removeable shelter may leverage electrical contacts in accessory mounting ports on the roof, crossbars, and/or truck bed of the vehicle. The removeable shelter may also communicate wirelessly with the electric vehicle. The removable shelter may include any of various integrated electronic accessories that can be powered by the vehicle battery, including, but not limited to, external lighting, external proximity sensing, proximity-based external lighting, interior lighting, air temperature control, other temperature control, speakers, charging ports for mobile phones and/or other devices, and/or other features.

Abstract: A system and method for providing a fire department connection (FDC) to a building fire sprinkler and/or standpipe system comprising carrying and transporting the FDC on a pumper truck with the fire department. The FDC is removed from the pumper truck and coupled to the inlet of the building with a quick-connect. The quick connect is capable of releasably coupling the FDC to the building inlet of a building fire sprinkler and/or standpipe system. When finished, the FDC is removed from the inlet of the building and replaced on the pumper truck.

Abstract: A fire sprinkler valve trigger has a body or tube segmented into opposite segments joined together at a joint by a fusible material with a predetermined and selected melting temperature less than a melting temperature of the opposite segments. An exterior of the body or tube comprises a layer added to the exterior, and comprising a preselected color corresponding to and designating the melting temperature of the fusible material. The body or tube, including the joint and the fusible material, being exposed and visible so that the layer on the exterior of the body or capsule is exposed and visible.

Abstract: An air filter for providing a reusable frame and disposable filter media. The air filter includes a frame defining a channel into which a filter medium is removably received and replaceable with another filter medium. This frame also provides a nonconductive static electricity isolator for static charge retainment. A sealing member is secured to the outer surface of the frame to provide a seal between the frame and the HVAC filter mounting assembly into which the frame is inserted. The sealing member is configured to insure an air tight seal such that the air is forced through the filter medium before the air is circulated into a room.
