Abstract: A sheet of inkjet printed photographic images having orthogonal fiducial marks extending along a leading edge of the printed field and along a lateral side of the printed field. The fiducial marks register with the printed field and provide information regarding the location of the images in the printed field relative to the larger sheet. The registration of the lateral side fiducial mark and print field is accomplished by exercising the nozzles of the print head at each pass of the print head during the printing of the photographic image.

Abstract: An image forming apparatus includes a fiducial reference point sensor that individually monitors the position of first and second fiducial reference points on a moving print device that are in spaced relation to one another.

Abstract: A chart recorder or other applicable instrument uses the chart or other recording medium for programming purposes, thereby obviating the need for additional keypads and/or displays. By placing this chart onto the recorder, and by moving the pen to select among the available options, the unit is automatically programmed in accordance with the selections, without the need for controls other than those used for pen and/or chart movement. Since the position of the chart is known due to the spatial alignment with the start position, and the position of the marker is always known, selection of the programming features is unambiguous according to the invention. In addition to circular chart recorders, the invention applies to strip-chart recorders, plotters, printers, and other pieces of equipment wherein the position of a marker and/or paper or other substrate is known or determinable.

Abstract: A method and apparatus is provided for producing single width barcodes in a continuous, serpentine pattern. This pattern provides continuity of operation for laser marking instruments and thereby results in the formation of more uniform and higher quality barcode indicia. The use of a continuous serpentine pattern also increases the speed at which the code may be written onto a substrate. This marking method is particularly appropriate for use in marking a wide variety of materials including semiconductors, metals, plastics and ceramics.

Abstract: A graphic recording method and a graphic recording apparatus capable of dealing with the multi-channel measurement data involving quick and minute changes, without causing a trouble in accurate reading of the recorded data, in a simple and compact configuration. In the apparatus, the multi-channel measurement data are recorded by plotting a monochromatic continuous line for each channel of the multi-channel measurement data on a recording paper; and a channel discrimination mark having a distinctive color is plotted, with respect to each monochromatic continuous line, at a regular interval.

Abstract: A system and method for controlling printing to allow to obtain a long vertical line which is continuous even if a reduction in height of font is produced due to the occurrence of font change between the two consecutive print lines is provided.

Abstract: A method and apparatus are disclosed for conducting ground or near ground magnetic surveys in which the magnetic field measurements of the earth's total field, a component thereof, or a combination of components thereof, are made at continuous or near continuous (less than 20 feet intervals) measurement intervals. These measurements are recorded in analog or digital format by the apparatus which may include a corresponding chart recorder, recording on chart paper, magnetic tape or any appropriate recording device. The device includes manual switches for advancing the chart, making a recording, making a fiducial mark and for reversing the polarity of recording of the reading from the magnetometer.

Abstract: In the disclosed recording device, variable values are measured and recorded on a recorder carrier by moving the record carrier along a given direction. A number of recorders form a row and define separate tracks along the direction when the record carrier moves and trace lines along the tracks when actuated. The recorders are divided into a first group and a second group while suitable means measure the variable values. An energizing arrangement energizes a different recorder of the first group for each one of a number of ranges of measured values and energizes a different recorder of the second group for each one of a number of increments of measured values within each range. Each recorder of each second group is energized for the same corresponding increment regardless of the particular range.

Abstract: A converter for adapting a longitudinal mode, fiber optics cathode ray tube recorder, or visicorder, to operate selectively in either the longitudinal, Y axis mode or in the transverse, X/Z axes mode. The data to be recorded is displayed, initially, upon a control oscilloscope. Samples of the horizontal sweep and gate signals of the control oscilloscope are directed to the converter. Therein, the horizontal sweep signal is conditioned and amplified to provide the high current linear ramp signal necessary to drive the horizontal yoke of the visicorder. The data is synchronized with the gate signal to ensure identity between the visual display on the control oscilloscope and the data recorded by the visicorder. The converter also includes circuitry for selectively printing start and end of trace markers, a time line marker, and external time code data in association with the recorded data, to facilitate its subsequent analysis and identification.

Abstract: There has been provided, in accordance with the present invention, a cathode ray tube recording system which includes means for superimposing grid lines on the resulting record. The grid lines so-recorded for each complete record are not shifted. At the beginning of each new record, however, a randomly selected bias is applied to the grid line positioning circuit whereby the grid lines are started on a fresh phosphor position for each subsequent recording but selected on a random basis.

Abstract: A printing apparatus for multiple signal printout has separate multiplexers for analog and pulse channels. The multiplexed analog signal is digitized, formatted, and applied via a selector to an adder, alternatively and selectively, the pulses are applied as digital signals to the adder. The adder receives zero offset numbers which differ for the different channels and the resultant numbers are applied to a one-out-of-n decoder driving printing electrodes. The system is under control of a cyclically addressed ROM whose outputs controls the multiplexing and furnishes the offset numbers. A clock sequencer times each acquisition frame.

Abstract: A recording device for plotting the curve of at least one measured quantity which is reproduced through an electrical signal, including a recorder, a recording or graph carrier, and means for producing relative movement between the recorder and the recording carrier into two directions extending approximately perpendicularly to each other. A time multiplexer alternatingly periodically connects the control input of the recording device to a generator for a reference line signal and to at least one generator for a measured quantity signal. In a suitable construction of the invention, it is proposed that to the particular input of the multiplexer to which there is transmitted the measured quantity signal, there is connected the output of a second time multiplexer which is periodically switched between a plurality of inputs to which there are applied a plurality of measured quantity signals, and wherein the switching of the multiplexer is effected at a predetermined beat.

Abstract: In accordance with illustrative embodiments of the present invention, well logging data in analog or digital form is recorded by a cathode ray tube recorder. A representation of the CRT beam is repetitively swept across a recording medium while being modulated with representations of the well logging signals. This modulation varies as a function of the rate of change of the well logging signals to produce an even density recording. Coding of the recorded lines or traces and the areas between selected traces can be accomplished. This coding of the lines is also varied in dependence on the well logging signal rate of change to produce a uniform coding presentation. Depth information can be recorded on the recording medium by writing depth numbers and depth lines on the record medium. Moreover, a section by section visual presentation of the data can be produced while it is being recorded.
