  • Patent number: 7894942
    Abstract: A device for controlling devices in a monitored space. A sensor senses an event in an initial state indicating an occupant may be present in the monitored space. A switch activates the controlled device in response to the sensed event. A processor enables the device to change from the initial state to a first state in response to the sensed event, with the first state indicating that the occupant may be in the monitored space. The device also changes from the first state to a second state while determining whether the occupant continues to be in the monitored space in response to a query challenge. The device next changes from the second state to the initial state in response to the determining indicating that the occupant is not in the monitored space. The switch deactivates the controlled device in the initial state in the monitored space.

  • Publication number: 20090113777
    Abstract: A set trigger assembly that enables a user of a firearm with a trigger, return spring plunger, and a return spring plunger spring to modify the trigger mechanism on-demand to reduce the trigger pressure required to fire the firearm by enabling the user to retract the return spring plunger and then return the return spring plunger to its initial position by insertion of a lever which is used to apply force to a return spring plunger so as to force the return spring plunger away from the trigger.
