Abstract: An ambient air condition sensor housing includes a front portion releasably coupled to a rear portion and defining an interior space therebetween adapted to retain at least one ambient air condition sensor. The rear portion defines apertures for passage of the ambient air therethrough. A labyrinth having a plurality of spaced apart upstanding walls is integrally attached to an inner surface of the rear portion and is positioned so as to cooperate with the air condition sensor. Each wall of the labyrinth includes a slightly arcuate configuration for funneling the ambient air toward the air condition sensor. The rear portion and labyrinth are completely covered with a black coating so as to minimize light reflectivity within the interior space whereby to enhance proper functioning of the air sensor.

Abstract: A system and apparatus for preventing unauthorized access to a trigger of a firearm comprises a database of PIN numbers associated with a plurality of trigger locks and access tokens, each corresponding trio being represented by a common identification code. At a point of purchase, a consumer receives a two-piece trigger lock secured about the trigger of a purchased firearm as well as an access token. Each token includes a unique number or configuration of ferro-magnetic wires. Each trigger lock includes a magnetic read head which generates voltage pulses when a token is positioned in close proximity thereto. This positioning causes the ferro-magnetic wires to switch magnetic states, thus invoking electromagnetic impulses. If a background check of the firearm purchaser, initiated at the point of purchase, is approved, a central computer coupled to the database and to a computer network displays a personal identification number (PIN).

Abstract: A voice-controlled shower system for use with a conventional shower assembly includes sources of hot and cold water, a showerhead, and a conduit for delivering water from the water sources to the showerhead. Each water source includes a control valve coupled to a control unit. The control unit is adapted to store electric impulses representative of a predetermined vocabulary of voice commands. The shower system further includes a receiver for receiving a speech input from a user and delivering corresponding electric impulses to the control unit. The electric impulses of the speech input are compared by the control unit to the electric impulses of the vocabulary of voice commands, the control unit actuating predetermined control valves upon recognizing a match so as to start or stop the water flow from the water sources to the showerhead or to adjust the water temperature.
