Abstract: A method and to a device for dispensing data from a tachograph to an endless printing medium. A first division is plotted in the longitudinal direction of the printing medium, and a second division is plotted transversely with respect to the longitudinal direction of the printing medium. The first division represents a predetermined unit of time, in particular a day in generalized time coordinates, and the second division represents at least one variable recorded by the tachograph during the unit of time, the at least one variable is depicted by at least one graph.

Abstract: A process chart recorder for the on-line recording of process measurement data that has a dot-printing head. In order to develop a chart recorder arrangement having a dot-printing head of the generic type to the extent that the overall printing operation can be effected more easily using mechanically or electromechanically simple means, the printing actuation of the dot-printing head and the actuation of the pen wheel is effected through a common stepping motor. The stepping motor is provided with mechanical means through which the stepping motor is coupled to the pen wheel in a manner causing rotation in one direction and blocking rotation in the opposite direction, with the result that, in one direction of rotation of the stepping motor, only the pen wheel can be actuated and, in the other direction of rotation, the entire dot-printing head can be lowered for printing.

Abstract: Ruled lines printed on a graph paper g are optically detected by a vertical ruled line reading sensor and a horizontal ruled line reading sensor. Ruled line spacing Dp in a plotter coordinate system P is measured and compared with ruled line spacing Dg in a coordinate system G of a given graph paper, and the correspondence relationship between coordinate system G of the graph paper and coordinate system P of the plotter is determined. When a drawing command is inputted, a a coordinate Zc in the drawing command is treated as coordinate Zg in the coordinate system G of the graph paper, and this coordinate Zg is converted to coordinate Zp in the coordinate system P of the plotter, using the correspondence relationship. The drawing command is then executed with respect to the converted coordinate Zp. As a result, figures or waveforms that match the ruled lines of the graph paper can be drawn. Ordinary graph paper can be used because the ruled lines are read, contributing to ease of use.

Abstract: A chart recorder method and apparatus wherein a recording head records a plurality of different colored line segments on a recording medium, a head drive moves the recording head and the recording medium reciprocally relative to each other in a scanning direction, a recording medium drive moves the recording medium and the recording head relative to each other in a sub-scanning direction, a component receives a plurality of signals to be recorded on the recording medium as a corresponding plurality of traces to be recorded by the recording head, and a control circuit controls the recording head so that at least one of the traces is formed by line segments which change color cyclically.

Abstract: A mechanical shape sensor measures and provides a two-dimensional representation of the contour of a person's thighs and buttocks or the dorsal and lateral surfaces of a person's trunk for facilitating the fabrication of custom contoured seat cushions such as for use in a wheelchair. The mechanical shape sensor is integrated in a chair-like base capable of multiple adjustments to accommodate a range of dimensions and sizes of persons being measured. The mechanical shape sensor converts the three-dimensional contoured support surface of a person seated on an array of movable support elements into a two-dimensional format which is recorded on a data sheet in a form which is easily transmitted via telecommunications link to a central locatin for fabricating a custom contoured seat cushion. Each of the moveable support elements is coupled to a position marker in the data recorder.

Abstract: The inventon relates to a method and apparatus for marking or recording patient-related information and other necessary data in connection with X-ray imaging on a certain section of a film (6) by using a marking apparatus (2) which is movable relative to film (6). In the method, markings are made latent on film (6) in a manner that the markings become visible in connection with film development. The marking is effected as a sequence, line-directed deviation of a marking being obtained by moving the marking apparatus and the film relative to each other. The marking apparatus (2) used in the method is provided with marking elements which are brought into contact with film (6) for producing a marking on film (6), vertical deviation of alphanumerical marks included in a marking being achieved by individually controlling the operation of each marking element included in the marking apparatus.

Abstract: A piggyback recorder for use in a printer terminal having a first recorder for printing a first set of data on a document, such as a receipt document. The piggyback recorder is detachably mounted piggyback onto the first recorder, thereby providing a second recorder to the terminal for printing a second set of data on the document. The piggyback recorder comprises a piggyback print member which is capable of printing the second set of data, a mounting member for mounting the piggyback print member directly onto a first print member of the first recorder, a piggyback platen, a second mounting member for mounting the piggyback platen directly onto a first platen of the piggyback recorder, and a solenoid for providing relative movement between the piggyback print member and the piggyback platen.

Abstract: An automatically balancing type pen recorder, which is compact in size and is highly reliable in operation, comprises an integral servo unit formed of a single printed circuit board which incorporates therein a pen carriage and an automatic balancing mechanism adapted to move a recording chart in a direction perpendicular to the direction of feed of the chart, in response to the magnitude of a measuring signal.

Abstract: A data plotter for use in a multi-channel chart recorder operable to record time-variant analog scalar components of vector data signals on a moving recording medium. The data plotter comprises stationary printing means, preferably a thermal print head, for plotting vectors and other data derived from sampled scalar components as an aid in the interpretation of their analog traces.
