Abstract: The present disclosure generally relates to the automated testing of a system that includes software or hardware components. In some embodiments, a testing framework generates a set of test cases for a system under test using a grammar. Each test case may perform an action, such as provide an input to the system under test, and result in an output from the system under test. The inputs and outputs are then compared to the expected results to determine whether the system under test is performing correctly. The data can then be interpreted in the grammar system or used as input to a fault isolation engine to determine anomalies in the system under test. Based on identified faults, one or more mitigation techniques may be implemented in an automated fashion.

Abstract: An apparatus for recording a plurality of variable analog signals individually and sequentially scanned during the recording operation. The analog signals are digitized, and the digital values multiplexed into a microprocessor which uses a stored program to determine significant changes in the scanned analog input and to store only meaningful data representing a significantly changed analog input in a buffer memory for subsequent recording on a recording chart. Specifically, the apparatus provides a selection of input values to be recorded whereat the recorded input values differ by a predetermined amount with respect to the measured value or the time basis of a recording chart. The buffer memory serves to match the velocities between scanning of the inputs and the printing of the measured variables since the inputs are scanned at a rate which is much higher than the print rate of the recorder to allow a follow-up of the measured variable which provides equidistant recording of the measured values.

Abstract: A transfer ink film having one major surface containing sublimable dyes is passed through a path between the surface of a drum and a thermal head having a plurality of heating elements which are selectively energized in response to input image signal, while a record sheet is fed from a record-sheet feed part of a printing apparatus to said path so as to be superposed on the transfer ink film. As a result, the dyes are transferred by sublimation from the transfer ink film to the superposed record sheet. During the feed of the record sheet, any dust particles or the like attached to the surface of the sheet are removed by an adhesive roller, an electric discharge brush and so on whereby a high-quality image can be obtained on the record sheet. The record sheets are contained in the form of a stack in a sealed cassette which is detachably inserted into the record-sheet feed part of the printing apparatus.

Abstract: A multipoint recorder has a multicolor ink cartridge arranged to be selectively aligned with a recording head having a plurality of selectively energizable recording elements whereby a color from the multicolor ink cartridge is selected for printing by the recording elements. A fixed color operation of the recorder enables a recording to be made in a single color by maintaining a preselected alignment of the recording head and a desired color in the multicolor ink cartridge. Alternatively, the color of the recording can be selectively altered at any time to produce a multicolor recording by selecting a corresponding color from the multicolor ink cartridge for each recording.

Abstract: A string of short pulses is impressed across the input circuit of a multipoint recorder and a pulse magnitude detecting circuit. If the input circuit is open, the magnitude of the pulses appearing at the pulse magnitude detecting circuit is higher than would be the case if the input circuit were completed by a normal input device. The pulse magnitude detecting circuit is operable to apply to the measuring circuit of the multipoint recorder a positive potential whenever the pulse detecting circuit detects pulses of a magnitude indicating that the input circuit is open. As a result, the multipoint recorder is driven upscale to its limit where the particular point which is open-circuited is identified by a printed indicia.

The bridge outputs are amplified and multiplexed into a single channel strip chart recorder having a single, heated stylus which records two separate traces based on the signals received from the two sensors.Heat to the recordinng pen or stylus is turned off during switching excursions of the pen between the two traces so as to eliminate shading and marking which would otherwise occur on the recording chart between the traces at slow chart speeds.

Abstract: A method and an apparatus are taught in which variable analog data, representative of a plurality of physical parameters are recorded on a thermo-sensitive recording paper which is movable along an axis representative of time. A thermal recording head is transversely movable over the recording paper for sequentially recording the variable analog data in their order of value in a unidirectional sweep of the recording head over the paper. The variable analog data signals arriving in the recorder are updated to obtain their instantaneous values and are gathered and transferred to memory locations in a sequential order. The sequential analog data is then tabulated in the order of value in an ascending or declining magnitude and recorded in such order on the recording paper. Successive recordings of tabulated analog values provide tracings on the recording paper giving, in graphic form, a continuous read-out of physical parameters.
