Title: Intersymbol interference channel coding scheme
Inventor: LAROIA RAJIV
IPC: H04L27/00
Filed: 1994-04-20
Granted: 1999-06-15
Abstract: Intersymbol interference and precoding loss are minimized by combining the precoding and coding operations. An intersymbol interference coder uses a feedback loop to apply a dither sequence to a sequence of input signal points. The dither signal applied to each input signal point is a function of the previous signal points in the sequence.  The intersymbol interference coder implements, for example, a trellis coding operation by selecting one of several different modulo operations to determine the magnitude of the dither signal, the selection being made in response to the current trellis state. The sequence of signal points output from the intersymbol interference coder generates a valid sequence of the trellis code input to the Viterbi decoder.

Abstract: A system for eliminating differential scan line bow from raster output scanners aligns at least the chief exit ray of each scanning light beam with the system axis. By aligning the chief exit rays to be essentially parallel to the system axis, the overall bow is reduced, and the bow of different scan lines is essentially identical. Thus, bowed scan lines from different stations in a multi-station printer, or from different passes in a multi-pass printer are generally identical and aligned.

Title: Method for improving wear resistance of polymeric bioimplantable components
Inventor: HAMILTON JOHN V
IPC: A61L27/16
Filed: 1996-04-02
Granted: 2006-12-05
Abstract: Wear resistance and oxidation resistance of bioimplantable polymeric parts is improved by packaging the parts within flexible, gas impermeable containers while subjecting the containers and the parts to a relatively high vacuum force. The containers are heat sealed while subjected to the vacuum force such that, upon sealing, hydrostatic pressure is exerted on the part. Following sealing of the packages,-the packages and their contents are irradiated to an extent sufficient to sterilize the parts and to promote crosslinking within the part. Alternatively, the same property enhancements can be imparted to polymeric parts by packaging the part within rigid or flexible containers, minimizing the oxygen content within the containers, pressurizing the containers with an inert gas, or with a mixture of hydrogen and an inert gas, to greater than 1.5 atmospheres, and irradiating the part and the container.

Abstract: A method and receiver for demodulating a DS/CDMA signal increases a receiver's (60) sensitivity and as a result, the system capacity of a DS/CDMA cellular communications systems.  A Reduced State Sequence Estimator (RSSE) (68) finds a path (210) with the highest energy.  An efficient method and apparatus for determining the path energies (212) selects a new path (210) to differ from a previous path (210) by a single reduced state (200).  A difference (306) between an I and Q magnitude of the new and omitted reduced state (200) is computed (304).  This difference is added to the previous path's total I (308) and Q magnitude, to compute the new path's I and Q magnitude.  These I and Q magnitudes are used to compute a path energy (322) and the highest path's energy (326) is used to select the best path for decoding (70).
