Title: Simultaneous multiple layer curing in stereolithography
Inventor: SNEAD DAVID E
IPC: B29C64/124
Filed: 1991-10-30
Abstract: A method of and apparatus for slicing a three-dimensional object representation into a plurality of layer representations. The layer representations are subsequently used to form the object layer-by-layer from a solidifiable material by stereolithography (711). If not already provided in the object representation, a plurality of layer boundary representations are first formed, and then the boolean difference (17), of successive layer boundary representations are computed to derive boundaries of up and down-facing regions, enabling different cure parameters to be specified for these different regions. In another method, the depth of the curable material within the objet underlying a selected area element is determined and compared to the depht to the minimum solidification depth of the material. The area element is exposed to solidifying synergistic stimulation only if the depth of the material equals or exceeds the minimum solidification depth. A next layer is created over the first layer without curing the first layer, if the depth is less than the minimum solidification depth. Another method and apparatus (714) eliminates or substantially reduces curling effects in stereolithographically formed objects.  Synergistic stimulation is applied to a curable material to form a three-dimensional object through the build up of successive layers.

Abstract: A main CPU in a data transmitting section applies a packet number recorded in a packet number memory to a block data when transmitting the latter, and increments and updates the packet number upon completion of the transmission. A sub-CPU in a data receiving section determines whether the packet number applied to the block data received is the updated number or not, in order to determine whether the data is a retransmission of previous data or a transmission of new data.      If the block data received is a re-transmission of previous data, the data received previously is discarded.      If the block data received is new data, the data received previously is processed.

Title: Optical Fiber Splice Verification System
Inventor: DEVEAU GEORGE F JR
IPC: G01M11/00
Filed: 1993-08-25
Abstract: The splice verification system (10) of the present invention verifies the efficiency of an optical splice by measuring the scattered light escaping from the splice. Specifically, the preferred embodiment performs such scattered light measurement within a photodetection area which is substantially free of all ambient light. Furthermore, the verification system includes a reference power module (12) which, prior to creating an optical splice, measures the level of the optical signal being transmitted out of the end of an active fiber. The present invention then provides means to correlate the level gauged as a reference signal level relative to the amount of scattered light lost from the optical splice. The ratio of these two measured light levels may then be used to determine whether the amount of scattered light lost from the optical splice is acceptable given the particular constraints of the optical system in which the splice is employed.

Title: Equalizing Amplifier
Inventor: ROSS JOHN D
IPC: H04N5/205
Filed: 1993-10-13
Abstract: Equalizing amplifying circuitry for compensating frequency dependent losses occurring in a signal transmitted over a network such as a cable.  The circuitry includes an equalizing network responsive to the signal transmitted over the cable, the equalizing circuitry having a predetermined frequency response characteristic.  The output signal from the equalizing network is applied to an amplifier and an attenuator applies a portion of the the amplifier output as a positive feedback signal to frequency response characteristic modifying circuitry to vary the amount of current passing through the equalizing circuitry as a function of the amplitude of the positive feedback signal to thereby effectively modify the frequency response characteristic of the equalizing circuitry. Summing circuitry responsive to the signal transmitted over the network and to the output signal from the amplifier provides a corrected signal in which the frequency dependent losses introduced by the network are compensated for with a single control.

Title: Saddle coil for cathode ray tube deflection systems
Inventor: NELLE FRIEDRICH
IPC: H01J9/236
Filed: 1994-01-04
Abstract: A process and a device for producing self-supporting saddle coils (96), where first, a winding receiver (10), which has a base (11) and a cutout (13), is produced to form saddle coils (46). Segments (12) can be attached to the inside contour of the cutout (13). These segments (12) are spaced with respect to each other. These spaces, also called slots (14), serve to receive wires running in the Z-direction. The constructed length of the segments (12) is such, that their ends extend beyond the base (11), thus forming the chambers (16.u, 16.o) between the edges (15.o, 15.u) and the ends of segments (12) that curve away from the centerline. This winding receiver (10) is wrapped by a winding device (21), which wraps the wire in the slots (14) and the chambers (16.u, 16.o). When the winding pass of saddle coil (46) is formed, the wrapping wire (32), covered with thermoplastic material, is heated so that the windings of the wrapping wire (32) are bonded to each other, after cooling. The segments (12) are then removed from the cutout (13) and the finish-baked saddle coil (46) can be pulled out of the cutout (13).
