Title: Rectification of a laser pointing device
Inventor: TREPAGNIER PIERRE C
IPC: G01B21/04
Filed: 1994-10-11
Abstract: Methods of compensating for errors in a laser pointing device, particularly for use in three-dimensional applications, by accurately controlling the angle that the laser beam makes in space. A method for rectifying a laser pointing device that aims a laser beam by deflecting the beam through a plurality of optical deflection devices each directed by a galvanometer controlled by an input. In the method, the laser pointing device is established in an accurate angular relationship to at least four fiducial points. The angular errors internal of the laser pointing device are determined by comparing actual galvanometer inputs to nominal galvanometer inputs, assuming no error in the established angular relationship. The actual galvanometer inputs are those that aim the laser beam at the fiducial points (while recognizing the existence of the internal errors), and the nominal galvanometer inputs are those that would aim the laser beam at the fiducial points assuming no internal errors in the laser pointing device. The angular errors are stored in a form for use during scanning by the laser pointing device to compensate for the internal errors in converting nominal direction numbers computed by a control to actual galvanometer inputs.

Title: Valve for fire fighting installation
Inventor: SUNDHOLM GORAN
IPC: A62C35/68
Filed: 1994-01-31
Abstract: The object of the invention is to for a fire fighting installation with a high operating pressure provide a new valve which is reliable without access to electric current and is of a simple structure.      The valve has a spindle (6) which is movable between a stand-by position and an activated position. A secondary liquid source (9) with a low pressure acts on the spindle in the direction towards the stand-by position and the pressure of a high pressure liquid source (1) acts via the valve inlet (4) in the opposite direction on a shoulder face (13) formed in the spindle. When the pressure in the secondary liquid source falls due to liquid delivery to a released spray head in the installation has fallen to a predeterminable value the pressure of the high pressure source on the shoulder face (13) drives the spindle to activated position and opens direct connection from the inlet (4) of the valve to its outlet (5).

Inventor: CHAVEZ DAVID LEE JR
IPC: H04W8/04
Filed: 1995-05-16
Abstract: Allowing multiple copies of authentication information for a mobile telephone to exist in switching nodes of a distributed switching system. The mobile telephone is only registered on one switching node at a time. One copy is maintained on the resident switching node, and another copy is maintained on theswitching node on which the mobile telephone was last registered other than the resident switching node. If the mobile telephone normal only registers on the resident switching node and one other switching node, the authentication information is present on both switching nodes, and both always have the authentication information to register the mobile telephone stored internally which speeds up the registration process. Further, the authentication information does not have to be repeatly communicated through the distributed switching system. If the switchingnodes are arranged into an authentication hierarchical structure, the authentication information remains stored on a switching node that last used the authenticationinformation within the authentication hierarchical structure, so that all switching nodes in that authentication hierarchical structure can access the authentication information.
