Abstract: A stream cipher cryptosystem includes a pseudo-random bit generator receivin g a key and providing a vulnerable keystream vulnerable to crytanalysis, and a  non-linear filter cryptographic isolator to convert the vulnerable keystream  into a protected keystream. The non-linear filter cryptographic isolator includes a multiplier for performing a multiplication function on the vulnerable keystream to provide a lower partial product array and an upper partial product array, and a simple unbiased operation (SUO) for combining t he lower partial product array and the upper partial product array to provide t he protected keystream. In example encryption operations, a plaintext binary da ta sequence is combined with the protected keystream to provide a ciphertext binary data sequence. In example decryption operations, a ciphertext binary data sequence is combined with the protected keystream to provide a plaintex t binary data sequence.

Title: Pipe joint assembly and method for using same
Inventor: HEUBACH GLENN C
IPC: F16L23/024
Filed: 2001-03-22
Abstract: The present invention relates to a method for sealing an end of a pipe to an external sealing surface. The method includes providing a pipe assembly which includes a pipe (2) and a flange (8).  The pipe includes a proximal pipe end (12) and a flared end region (16). The flared end region is integral with the pipe and is proximate to and continous with the proximal pipe end.  The flange is non-integrally disposed around the pipe distal to the pipe's flared end region. The method further includes securing, non-integrally and distally to the pipe's flared end region, the flange to the pipe so that proximal movement of the flange relative to the pipe is restricted. The flange is drawn toward the external sealing surface (4), which causes the flange sealing surface to bias the pipe's flared end region into sealing contact with the external sealing surface. Pipe assemblies which include a backup ring (38) having a tapered outside surface are also discussed. The methods and assemblies disclosed herein are particularly useful for joining lengths of multilaminate, especially dual-laminate, pipe.

Title: Model based detection and compensation of glitches in color measurement systems
Inventor: MESTHA LALIT K
IPC: G06T1/00
Filed: 2002-10-24
Abstract: A color sensor monitors the output of a color producing process and produces a signal representative of a color produced by the color producing process.  The signal can be used as feedback signal to control the process. Occasionally, the color sensor signal includes a component representing a transient error. A system model of the color producing process is used to predict reasonable sensor signals. A  comparison of the sensor signal with the predicted sensor signals is used to determine if the sensor signal is reasonable. If the sensor signal is unreasonable, a substitute signal is used as the feedback signal to the control process. The substitute signal can be a predicted sensor signal or a signal based on historical system performance data.

Abstract: A method includes receiving at least two space-time coded signals from an antenna system associated with a first station, determining complex channel state information based on the received space-time coded signals, and sending the complex channel state information to the first station. In an alternative embodiment, a method includes transmitting at least two space-time coded signals in respective beams of a multi-beam antenna array, measuring a channel impulse response for each space-time coded signal at a second station, and sending an indicia of a selected set of least attenuated signals from the second station to the first station.

The beams transmit a signature code embedded in each respective space-time coded signal, and the signature codes are orthogonal so that the second station can separate and measure the channel impulse response corresponding to each space-time coded signal. The space-time coded signals include the selected set of least attenuated signals and a remaining set of most attenuated signals. In an alternative embodiment, a method includes selecting at least two beams of plural beams formed by a multi-beam antenna array associated with a first station for transmission of a corresponding at least two space-time coded signals produced by a space-time encoder, determining a time delay associated with each of the at least two space-time coded signals as received in each respective beam, and setting into a variable delay line the time delay corresponding to each beam, each variable delay line being coupled between the multi-beam antenna array the space-time encoder.
