Abstract: A rapidly installable and rapidly removable set of equipment (1-6, 11) which can be replaced by standard exchanges, furnished with individual electronic circuits for monitoring proper operation (1a-6a, 20a-23a, 30a-32a, 1 1a) assuming, at their level, a BITE function (Build [sic] In Test Equipment) for testing, for fault diagnosis and for issuing fault messages sent by data transmission to a central maintenance computer (7) itself formulating a report regarding the overall state of operation of the set of equipment. It relates more especially to the hardware parts of the electronic circuits for monitoring proper operation which are integral with the equipment (1-6) or with equipment parts (20-23, 30-32) and which are furnished with a nonvolatile memory (405) and by means of detection, selection and capture (403, 413, 423) into their nonvolatile memories (405), of the report formulated by the central maintenance computer (7).

Abstract: A method is disclosed for generating a sequential pattern of motor control instructions under control of a microcontroller for the purpose of controlling a motor. A pattern of motor control instructions is stored in a memory. A timing circuit is operable to generate a periodic output sync signal. The microcontroller is operable to initiate a sequential Read operation of the memory so as to cause sequential reading and output of motor control instructions from the memory in a predetermined order. Each of the read motor control instructions is then stored in a pre-load buffer after output from the memory. The contents of the pre-load buffer is then transferred to an output buffer in synchronization with the output sync signal, wherein the output of motor control instructions from the memory is not required to be periodic.

Abstract: A waveform generator for generating a smooth version of an original waveform which contains abrupt transitions, includes a phase accumulator incremented at successive sampling times to produce an output representative of the phase of the original waveform, a phase scaler arranged to convert the residual contents of the accumulator following a transition from phase to time, computing means responsive to the time to calculate a number of samples along a smooth transition, each offset by that time from the sampling times, and a sequencer to replace the otherwise abrupt transition with the sequence of samples from the computed smooth transition.
