Abstract: A first data slicer provides interim symbol decoding results responsive to multiple-level symbols in a digital television (DTV) receiver. Co-channel interference accompanying the multiple-level symbols is suppressed by using a first comb filter to reduce the energy of the co-channel interference before data slicing in a second data slicer. The first comb filter incidentally recodes the symbols supplied to the second data slicer. A second comb filter is used as a postcoder after the second data slicer, re-coding the data stream recovered by the second data slicer to generate supplemental symbol decoding results. Co-channel interference detector circuitry determines the amounts of co-channel interference energy in the interim and supplemental symboldecoding results. The interim symbol decoding results are available for use as final symbol decoding results only in the co-channel interference detector does not generate a current indication that the stream of symbols reproduced in the DTV receiver is accompanied by artifacts of co-channel interfering analog television signal that can be suppressed in the first comb filter response and that are of sufficient energy level to cause uncorrectable error in the data from the first data slicer.

Abstract: An apparatus for drilling holes in the steel casing of an a oil or gas well, and drilling into the surrounding earth, includes a number of components controlled by hydraulic fluid. A first hydraulic motor drives a steel milling assembly and a second hydraulic motor drives a rock drilling assembly. All assemblies are supported in a housing that is conveyed by conventional jointed pipe or coiled tubing down the well casing. Control components cause a carriage carrying the milling assembly to be indexed up a predetermined distance relative to the well casing, and then extend a mill bit gradually into contact with the well casing while being rotated by a hydraulic motor. After the mill bit completes a hole through the well casing, the hydraulic components retract the mill bit and index the carriage back down to its starting position to align a rock drilling bit with the hole that was just drilled in the casing. The rock drilling bit is provided on the outer end of a flexible drillstem to enable the rock bit to extend while drilling radially from the wellbore, through the hole in the casing, as it is rotated by the second hydraulic motor. The apparatus makes it possible to radially drill multiple holes through the metal casing and multiple corresponding long tunnels through surrounding earth, without having to be raised to the surface and re-lowered between operations.

Abstract: A system in which originating mail processors would upload pertinent mail piece information on addressees, pointers or other identifiers automatically and periodically to a data center. The recipient addressee of the mail piece would temporarily configure his digital postage meter or mail processor as a mail receiver so that the postage meter or mail processor would read the digital indicia that was affixed to the currently delivered incoming mail. The incoming mail would be date/time stamped, opened (optionally) and the unique identifier that was placed in the postal indicia would be read. The recipient meter or mail processor would periodically upload to the data center raw data on the unique identifiers or codes that have been received. If, the received unique identifiers or codes match with the sender unique identifiers or codes in a reasonable amount of time, as would normally be the case, the sent and received codes cancel out, or are kept for statistical information on delivery times, etc. Non-matched codes could be flagged and reported to the originator for further investigation. Thus, the data center may be able to locate mis-sent or mis-routed mail and automatically feed back information on undelivered or undeliverable mail.

Title: Geophysical exploration system using seismic vibrator source which provides a composite sweep
Inventor: HOLLINGER DAVID P
IPC: G01V1/00
Filed: 1997-10-27
Granted: 2001-10-16
Abstract: A system for geophysical exploration uses a single source (30) which emits signals over multiple octaves. The source is driven by a composite sweep signal having two or more sweeps, one of which covers the lower octave (10) while the other sweeps cover the remainder of the bandwidth. The signals covering the lower portion are reduced in the case of a sweep which varies linearly with time in proportion to the square root of the ratio of the sweep rate of the signals covering the upper end to the sweep rate of the signals covering the lower end. The signals are transmitted simultaneously. Because of the composite sweep the same energy spectrum is transmitted as with a sine wave sweep which extends over the entire frequency band, while reducing the peak power and radiator displacement required at lower frequencies to maintain a flat spectrum. The size of the equipment can be reduced.
