Title: Method and device for detection and correction of errors in atm cell headers
Inventor: MERINO GONZALEZ JOSE LUIS
IPC: H04L1/00
Filed: 1993-11-29
Abstract: SUMMARY           Method and device for detection and correction of errors in ATM cell headers. Of the type wherein it is made a series to parallel conversion (2) of the several data stream (1), obtaining a parallel data format of n bits, the clock rate of which is n times lower than the original.      From the parallel input data of the ATM header, a syndrome word (3) is generated according to a determined function that indicates that no error has been detected, that more than one error has been detected, or which bit has to be corrected when only one error has been detected.  The ATM cell headers are delayed (4) until the syndrome word has been completed, the error correction process (5) then being carried out, when required, in accordance with the syndrome word generated.      In addition, an individual indication (7) for external use is generated of the result of the detection and possible correction process made.      The device implements the method described.

Inventor: ALEXANDER DAVID M
IPC: A63B61/00
Filed: 1994-01-14
Abstract: A monitor system which combines manual and electronic operations is proposed as a method to identify and correct line-call errors which occur in the conventional line-call system used in the game of tennis.  The monitor system enables several persons seated in various locations in the stands to act as line-call monitors by identifying obvious or gross line-call errors committed by line judges.  The monitors communicate with the chair umpire by means of small hand held "call-box" transmitters each equipped with a push button which is pressed when the monitor detects a clear mistake by the line judge.  The chair umpire wears a small radio receiver unit which accumulates the separate or simultaneous decisions of the monitors and generates a short "beep" sound in a speaker or an external earphone if certain simple criteria are met.  The umpire can then make the appropriate overrule to correct the line-call error.

Abstract: Abstract Protective Face Mask System Using Varying Thicknesses of Energy Absorption & Dissi-pation Material A  protective  facial  mask  system  having  an outer, high impact, rigid, polycarbonate layer and an inner, flexible, relatively soft layer of energy absorption  and  dissipating  material  (e.g.  an viscoelastic polymer).   The inner layer has dif-ferent thicknesses (-1/8"-1/4"), affording greater (thicker) protection where underlying bone structure is weaker (e.g., nasal region), and thinner where the bone structure is stronger (e.g. over flanking, supra-orbital/glabella regions).   The mask covers the zygomatic, temporal, nasal and frontal bones, resting on the buttresses of the cranial facial area, and also can cover the maxilla and the man-dible sides.   At its upper perimeter,  the mask extends above the supra-orbital ridges, leaving the remainder of the frontal bone, eyes, nostrils, and mouth of the user open.   The inner layer closely contacts  and  conforms  to  the  contours  of  the person's face, preferably in face-to-face surface engagement.

Title: Density process control for an electrophotographic proofing system
Inventor: NORDEEN CHARLES K
IPC: G03G15/01
Filed: 1992-10-22
Abstract: A method for operating an electrophotographic proofing system for generating color proofs from image information during multiple imaging cycle proofing runs. Charge model information, development model information and toner replenishment model information are stored for each component color. Actual photoconductor charge characteristics are measured during the imaging cycles of the proofing runs. Actual toner characteristics from component color test patches developed during the imaging cycles are also measured. The photoconductor is charged during the imaging cycles as a function of the charge characteristics measured during a preceding imaging cycle for the same component color, and as a function of the charge model information for the color. The photoconductor is toned during imaging cycles as a function of toner characteristics measured from test patches during a preceding imaging cycle for the same component color and as a function of the development model information for the color. Working toner is replenished after the imaging cycles as a function of the development parameters used to tone the photoconductor during the imaging cycles for the same component color and as a function of the replenishment model information for the color. Charge model information and the development model information for each component color are updated as a function of measured values after the imaging cycles.

Title: Corrosion inhibiting method and inhibition compositions
Inventor: RIGGS OLEN L JR
IPC: C23F11/08
Filed: 1992-11-05
Abstract: The present invention provides a method and compositions useful for inhibiting corrosion of a corrodible metal resulting from contact of water and air with the metal. In this method, a stannous salt and a hydrocarbyl substituted succinimide of a polyethylene polyamine are added to the water in minor amounts and cooperatively reduce corrosion of the metal to a substantially zero rate.  While the amount of each agent for an effective inhibition is minor, say in the range of from about 0.1 to 100 ppm, a relatively concentrated solution is required for addition to the water. Suitable solvent media include the lower alkanols and mixture thereof with or without added water. Isopropanol is preferred. The solvent component of the compositions also varies depending upon the particular imide and/or salt component employed and the concentration desired. In general, the lower alkanol portion of the medium is in the range of from about 15 to 100 volume percent and the water portion is in the range of from about 0 to 85 volume percent. A  medium in the range of from about 50 to 67 volume percent water is preferred. The relative amounts of the imide and/or stannous salt components desirably used varies depending upon the nature of the cooling water in which the agents are employed. Satisfactory relative amounts by weight for each to the other at set forth above, are in the range of from about 0.5 to 10, preferably 0.8 to 2 and more preferably about 1 to 1 weight ratio.
