Title: Shaped shadow projection for an electron beam column
Inventor: MANKOS MARIAN
IPC: H01J37/305
Filed: 1999-04-05
Abstract: A shaped electron beam column focuses electrons from an electron source (102) to produce a shadow image (114) of a shaped aperture (104) on a writing plane (108). The shadow image of the shaped aperture is the defocused image of a shape aperture. This defocused shadow image is in the object plane (112) of the shaped electron beam column. The shadow image in the writing plane is defocused because an electron beam lens (106) produces a focused image (110) of the electron source off the writing plane. The size of the shadow image on the writing plane may be altered by adjusting the electron beam lens to change the distance between the electron source image and the writing plane, i.e., defocus. Thus, a relatively large shaped aperture may be used in comparison to shaped apertures used in conventional electron beam columns. Further, only a small total linear demagnification may be used, which permits the length of the shaped electron beam column to be decreased. Consequently, the electron-electron interactions are reduced resulting in increased edge resolution of the image on the writing plane and increased current in the shaped electron beam column thereby increasing throughput.

Title: A read-only memory and read-only memory devices
Inventor: LEISTAD GEIRR I
IPC: G11C11/56
Filed: 1998-08-28
Abstract: A read-only memory is made electrically addressable over a passive conductor matrix, wherein the volume between intersection of two conductors (2; 4) in the matrix defines a memory cell (5). Data are stored as impedance values in the memory cells. The memory cells (5) comprise either an isolating material (6) which provides high impedance or one or more inorganic or organic semiconductors (9), preferably with an anisotropic conducting property. The semiconductor material (9) forms a diode junction at the interface to a metallic conductor (2; 4) in the matrix. By suitable arrangement of respectively the isolating material (6) and semiconductor material (9) in the memory cells these may be given a determined impedance value which may be read electrically and corresponds to logical values in a binary or multi-valued code. One or more read-only memories (ROM) may be provided on a semiconductor substrate (1) which also comprises driver and control circuits (13), to accomplish a read-only memory device. The device may be realized either planar or also volumetrically by stacking several read-only memories (ROM) in horizontal layers (15) and connecting them with the substrate (1) via addressing buses.

Title: Key transforms to discriminate between beams in a multi-beam satellite communication system
Inventor: DENT PAUL W
IPC: H04W12/00
Filed: 1998-12-08
Abstract: A method and apparatus is described for transforming a key variable used for scrambling mobile data traffic between a terminal and a network in alternate ways based on a value transmitted to the terminal from the network. Transformation is accomplished by passing portions of the key variable through a series of S-boxes, which provide a mapping between inputs and outputs. The method and apparatus is explained also in the context of a satellite communications system, in which a terminal can be located in a different continent/country from the terminal's home location. Enciphered communication is enabled between the foreign satellite gateway and the roaming terminal after the foreign gateway communicates with the terminal's native gateway. The native gateway transmits one or more cipher variables in the communication. Moreover, the value determining which way to cipher the data traffic can be based on numerous factors, including aspects of the satellite communication system.

Filed: 1999-04-14
Abstract: A first coupling member has a peripheral facing surface with a pair or annular slots (64, 66), each of a different length and width. A second coupling member has a lock ring (40) longitudinally slidable thereon with a facing surface having a pair of annular raised locking tabs (76, 78) sized to correspond to the respective annular slots. A resilient annular spring (42) mounted within the lock ring urges it toward the first coupling member so that the locking tabs engage their respective slots when the coupling is tightened to a predetermined extent during rotation in the locking direction to releasably and positively lock the coupling. An indicator stripe (74) on the peripheral edge of the first coupling member is exposed before the locking tabs and slots are engaged. Alignment between the respective locking tabs and slots allows longitudinal movement of the lock ring so that it covers the indicator stripe. One of the coupling members has a peripheral groove and two angularly spaced longitudinal keyways of differing widths which intersect the peripheral groove. The annular spring has an internal peripheral edge with a plurality of peripherally space spring tabs for holding it in the peripheral groove. A spring key on the internal peripheral edge of the annular spring has a width corresponding to the width of one of the keyways to rotationally position the annular spring with the coupling member. The annular wall of the lock ring has two angularly spaced keys of differing widths which correspond to the widths of the keyways and are received therein to angularly position the lock ring with the coupling member and the spring.
