Abstract: A method and system implementations thereof include receiving data from a passive optical network (PON) outside a building; wirelessly transmitting the received PON data to inside the building; and applying the received PON data to a network inside the building. The data received outside the building is from an optical line termination (OLT). The PON data wireless transmitted inside the building may be applied to an optical line terminal (ONT) inside the building. Alternatively, the wirelessly received PON data may be converted to Ethernet format and applied to a user interface and/or a gateway interface all inside the building. The wireless transmission of PON data may be via a first transceiver mounted on a surface outside the building and a second transceiver mounted on a surface inside the building. The surface may be a corridor, a window, a door, a walls and a façade.

Abstract: An aircraft comprising a fuselage and one or more propulsion motor devices attached to the fuselage. Each of the propulsion motor devices further includes means for controlling it with regard to its thrust amplitude and orientation about two axes of rotation. Each motor device can be controlled independently of the other motors. The aircraft may further include rudder and elevation means.

Abstract: A portable vacuum apparatus comprises a vacuum chamber to be filled with lidded jars, bottles or other containers containing foodstuff or other products for the purpose of storing the contents under vacuum. The vacuum chamber is composed of a platform covered by a layer of a resilient material serving as a seal, and of a removable cover seated on the platform. The chamber is pipe-connected to an electrically operated vacuum pump and to an automatic valve connecting the chamber with the atmosphere in open state. To evacuate the chamber and the jars the valve is manually closed and the pump is started exhausting air from the chamber and the jars. The valve is adapted to open automatically as soon as the required vacuum has been reached and to interrupt the electric supply to the pump motor. The valve is designed to open a wide passageway to the chamber causing the air to rush in and to create a shock wave.

Abstract: A laser beam delivery system is disclosed which includes laser apparatus for producing a laser beam, follower nozzle apparatus for receiving the laser beam and for directing the laser beam to impinge upon a workpiece and polar motion apparatus for moving the follower nozzle apparatus in a polar coordinate system and for directing the laser beam from the laser apparatus to the follower nozzle apparatus. The polar motion apparatus includes apparatus for receiving the laser beam along a first non-translatory rotation axis and for directing the laser beam along a second non-rotary translation axis, wherein the second axis is orthogonal to the first axis.

Abstract: A laser system having members disposed for rotation and translation and having an X-axis carriage and a Y-axis arm translated on a fixed linear screw and a Z-axis rotation unit including mirrors and pneumatic table providing the capability for three-sided machining of a vehicle chassis.

Abstract: A laser system including beam locating assemblies which bring the beam to two separate welding or cutting locations. A beam director apparatus is provided for receiving and directing the laser beam selectably along a fixed generally horizontal first axis in one of the two directions and a mirror is located for redirecting the beam along a second axis to a welding or cutting head.
