Abstract: A drill hole logging system (5) incorporates a computing system (58) at the surface and a deployment mechanism (40) for conveying a logging tool (10) configured to measure one or more geophysical parameters into a drill hole (20). A transmission means (57) communicates commands and data representing the geophysical parameters between the surface computing system and the logging tool. A borehole caliper (300) is employed to profile the inside of the borehole.

Abstract: A method is disclosed. The method includes receiving a print job, rasterizing the print job to produce rasterized data having a multi bit per pel print format, compressing the rasterized data into compressed data having a data section and a control section including compression control bits corresponding to each data value in the data section and transmitting the compressed data.

Abstract: Disclosed is a method, system and program product for performing multiple-pel print quality enhancement (PQE). As in known methods of PQE, a determination is made of an adjusted sub-pulse value of each pel of an image. In accordance with embodiments of the present invention, at least two adjacent pels are then grouped together and a determination is made of a combined pulse width value to charge the combined area of the at least two adjacent pels. Also determined is position information indicating the alignment of the pulse width within the combined area. The combined pulse width and position information is sent as input to a pulse width modulator operating at a speed equal to the video data rate of the printer divided by the number of pels for which the pulse width data is combined.

Abstract: Disclosed is a method, system and program product for performing multiple-pel print quality enhancement (PQE) using amplitude modulation. A determination is made of an adjusted peak amplitudes value of each pel of an image. At least two adjacent pels are then grouped together and a determination is made of a peak amplitudes value that will serve as a gray amplitude value for each pel in the pel group. Also determined is position information indicating the alignment of the peak amplitudes within the combined area. The combined peak amplitudes and position information is sent as input to an amplitude modulator operating at a speed equal to the video data rate of the printer divided by the number of pels for which the peak amplitudes data is combined.

Abstract: A duplex printing system including two print engines arranged in tandem for printing a first and second density patch on a print medium, at least one density sensing device adapted for measuring the density of the first and second density patches printed on the print medium by the two print engines and a control for controlling the adjustment of the print engines to enable the density and dot gain of the print output of the first and the second print engines to match. The printing system of the present invention is further characterized by the measurement of the density of the density patch printed by each print engine after the print medium has advanced through the printing system. Thus, the print medium and first and second density patches printed by each print engine is subjected to the same conditions and influences as a print job processed by the printing system.

Abstract: An method and apparatus for error checking. A known test pattern is written into a predetermined byte of a scan line. The method may include generating a known test pattern in a byte of a scan line and transmitting the scan line data through a first data path. The scan line data at the end of the first data path may be evaluated to determine if the test pattern is still in the predetermined byte of the scan line. If the pattern in the predetermined byte is correct, the test pattern may be removed from the predetermined byte and the scan line data may be transmitted to a print engine. If the pattern in the predetermined byte is incorrect, then a signal may be sent to terminate the transmission of the scan line data.
