Abstract: A LED light emitting group (1) apt to produce an outgoing light beam having its own optical axis (8) is equipped with a plurality of LEDs (18), distributed on a plate-shaped body (13) and having a fixed central plane portion (14) orthogonal to the optical axis (8) and a crown (13) of peripheral plane portions (16) tilted with respect to the central plane portion (14) and converging the one towards the other one and towards the central plane portion (14) and the optical axis (8); each one of said plane portions (14, 16) carrying a plurality of said LEDs (18).

Abstract: At least one aspect of the invention is directed to a ventilation device. The ventilation device includes a frame configured to be mounted to a barrier, and a plurality of air moving devices configured to be coupled to the frame and configured to draw air from a first side of the barrier to a second side of the barrier. The ventilation unit further includes a control device coupled to the plurality of air moving devices and configured to detect an out of tolerance condition of one of the plurality of air moving devices and control another one of the plurality of air moving devices to increase airflow though the another one of the plurality of air moving devices in response to the out of tolerance condition.

Abstract: An intelligent gun-ammunition system for a portable gun includes a gun having a handle; an owner recognition circuit having circuitry for recognizing an authorized grip on the handle and an activating circuit for allowing operation of a firing mechanism of the gun when authorized grip is recognized; ammunition for the gun; and an ammunition circuit communicated with the owner recognition circuit for allowing the ammunition to be fired when the owner recognition circuit recognizes the authorized grip.

Abstract: The invention presented in this work creates the possibility of a portable gun—revolver, pistol, carbine, riffle or hand-machine gun, to recognize its owner, in progressive levels of handling safety. Three levels of handling safety are established based on the evaluation of the grip force or its effect through material deformation or strain gage measurement. The first level of handling safety does not allow persons with grip force below a given limit, to shoot with a gun. The second level of handling safety enables the portable gun to recognize an individual as belonging to a smaller group than the first level. Now, the gun will only recognize for a successful firing an individual whose grip force, measured by one strain gage, fit into a small operational range, established and stored at the moment of acquisition by the owner. The third level of handling safety enables a portable gun to recognize an individual, as belonging to an even smaller group than in the second level.
