  • Patent number: 11682281
    Abstract: A security system and apparatus for a home or business is provided. The security system has a sensor connected to a liquid dispenser. The sensor is triggered upon the breaking of glass or a door of a building. The liquid dispenser, when activated, dispenses a non-toxic liquid marker. The liquid dispenser sprays a mist of the liquid on the intruder so that the intruder may be easily identified.

  • Patent number: 7770849
    Abstract: A cable clamp-bracket combination for rigidly connecting to an item to be suspended, especially a HVAC duct suspended from the ceiling of a structure. The combination utilizing, e.g., a commercially available cable clamp rigidly but removably connected to the clamp in a position where openings in the bracket surfaces mate with the cable channels through the clamp and a slot through the bracket mates with a clamp release projection on the clamp. The cable clamp includes a clamp clutch adjacent each cable channel for holding a support cable. The combination resulting in a rigid connection between the clamp and the item (e.g., duct) and a non-slip connection between the supporting cables and the item. The bracket can be formed from a flat plate having preformed openings and connecting elements by bending the plate into the desired form for holding the clamp and being securable to the, e.g., duct.
