Abstract: A system and a method for the transmission of signals representative of an event include a first low frequency clock (101) and a low frequency counter (102) for generating a first delay (TL), and a second high frequency clock (106) and a high frequency counter (104) for generating a second delay (TH). The system further includes a transmitter (105) for transmitting the representative signals after a delay from the event made up by the sum of the first and the second delay. The second delay can be generated also by an analogic device including for example a capacitor (99), and devices (97) for charging the capacitor up to the reaching of a preset voltage at its ends.

Abstract: A system for numerical control machine tools comprises contact detecting probes, powered by a battery, that transmit radio-frequency signals to associated interfaces. When the probes are not being utilized for checking cycles, they are in a low-energy consumption state, in other words the circuits of the probes are only partially powered. When the need arises, the circuits of a probe are fully powered by the battery, by a radio-frequency activation signal. The procedure for activating a selected probe includes the sending of a generic activation signal from the associated interface, the transmitting of an identification signal from all the probes that have been activated by the generic signal and the sending of a generic confirmation signal from the interface in reply to the identification signal of the selected probe.

In order to guarantee the repeatability of the delay time that cannot be avoided in the transmission of the change of state of the probe, the bit periods of the single bits that form the message are changed, with respect to a nominal bit period (TN) of the serial signal, on the basis of the delay or the advance at which there occurs the change of state, with respect to a theoretical instant (C0) pre-set within the nominal bit period.

Abstract: A measuring system for a numerical control machine tool comprising a detecting head (3), for contacting a workpiece (1) to be checked and for transmitting an optical coded signal (8) to a remote transceiver unit (11) that, in turn, can transmit an optical switch on signal (10) to the head (3). The transceiver unit (11) is connected, by means of a cable (45) including separate lines (43, 44) for the transmitted and received signals, to an interface unit (12), in turn connected to a computerized numerical control unit (13). In the event that faults occur in the transmission between the head (3) and the interface unit (12), a test takes place so as to identify in which part of the system the fault is located. A test signal is generated by suitable means (38) in the interface unit (12), transmitted from the transceiver unit (11) towards a reflecting surface (16), reflected by the latter, received by the transceiver unit (11) and sent to the interface unit (12).
