Title: Passive secondary surveillance radar using signals of remote ssr and multiple antennas switched in synchronism with rotation of ssr beam
Inventor: LITCHFORD GEORGE B
IPC: G01S3/20
Filed: 1992-11-06
Granted: 1996-05-07
Abstract: The range from which transponder replies can be received at a virtual secondary surveillance radar of the type described in U.S. Pat. No. 4,115,771 is extended by replacing the omnidirectional antenna previously utilized to receive replies from transponders within the range of the SSR with a stationary array of a plurality of directive antennas arranged in a circle and having radiation patterns pointing in different directions from the center of and covering a respective sector of the circle, and sequentially switching on the antenna of the array covering the sector in which the rotating beam of the associated SSR is then pointing.  In an arrangement in which the SSR and PSSR are so widely separated that in certain pointing directions the SSR beam overlies more than one sector of the antenna array, the antennas are sequentially switched on at calculated switching times determined from the pointing direction of the SSR beam and the times it takes in the geometrical arrangement between the SSR beam and the radiation patterns of the antennas of the array, for a given SSR interrogating pulse to propagate, from launch, along the beam until it reaches the line separating the first encountered sector from the next adjacent sector, between second and third sectors, and so on, such that a high gain directive antenna is always pointing in the proper direction to receive reply signals from a transponder intercepted by the scanning beam of the SSR.

Granted: 1999-05-25
Abstract: An optimising compiler for producing executable programs from code, high level languages compiles the code whilst generating data from which a callgraph may be constructed, and then recompiles the procedures identified in the callgraph in an order which reverses the topology of the callgraph while monitoring usage of hardware registers. Procedures which are rarely or never called, or result in termination of the program, are identified, and are modified if needed so that if called, registers which they may modify are saved prior to execution of the procedure and subsequently restored if necessary, so that in a calling procedure, subsequently recompiled, no account need be taken of possible register usage by the called procedure. This makes additional registers available to the calling procedure, and enables register storing and restoring which must otherwise be associated with the callsite to be eliminated.

Abstract: A cross-oriented multi-layer laminated plastic film is produced by first providing a flattened tubular plastic film having a outer plastic film layer with a first melting temperature and an inner plastic film layer with a second melting temperature lower than the first melting temperature, the outer plastic film layer having a molecular orientation substantially in the direction of the length of the tubular plastic film. The flattened tubular plastic film is passed from an expanding station in an expanded condition along a predetermined path in the direction of the length of said film to a collapsing station in a continuous manner. The expanded tubular plastic film is rotated about the predetermined path as the film passes from the expanding station to the collapsing station to effect cross-orientation of the outer film layer in directions inclined to the direction of travel of the tubular plastic film. The tubular plastic film is flattened at the collapsing station and pressure is applied to the flattened film at a temperature high enough to soften the inner plastic film but low enough not to soften the outer plastic film layer to an extent to cause the outer plastic film layer to lose its molecular orientation. The said pressure causes the opposite sides of the tubular plastic film to engage one another and to cause adjacent inner film layers to become bonded together and to the outer film layers to form a cross-oriented multi-layer laminated plastic film.

Abstract: The acceleration applied to a selected device such as a magnetic disc drive system can be detected by the use of an acceleration detector having at least one piezoelectric acceleration sensor unit. The sensor unit includes a piezoelectric element, a supporting member for the piezoelectric element and two electrical leads. The piezoelectric element is formed with a pair of elongate sheets made of a piezoelectric ceramic and an intermediate insulation layer interposed between the elongate sheets to generate a voltage difference  instantaneously therebetween in response to the acceleration of the acceleration detector. The support member is made of an electrically insulating resin, and has a concave which is formed with side and bottom walls and a top opening. The side wall is provided with a slit in which the piezoelectric element is tightly caught in such a manner as to divide the concave into two open-chambers and be supported by the support member in a cantilever fashion. The electrical leads extend into the concave to make electrical connections between the elongate sheets and the electrical leads. In the present invention, since the piezoelectric element can be attached accurately at a predetermined direction to the supporting member by forcing it into the slit, it is possible to stably supply the acceleration detector having excellent sensitivity to the acceleration without causing variation in detecting direction of the acceleration.
