Method for self-recognition, by a probe, of a communication protocol to be used to communicate with a base station (), the probe () being configured to emulate a plurality of communication protocols featuring respective activation procedures. Each activation procedure allows the base station to activate the probe to perform a checking cycle. According to the method, in consequence of a command given by a user by means of hardware interfaces () of the probe, the probe is set in a search state (-) where all the activation procedures are attempted and it is identified which of the activation procedures is completed positively. Then, the probe is switched to an operative state (-) based on the communication protocol featuring the identified activation procedure. Preferably, the activation procedure is identified after a predetermined number (N) of positive conclusions have occurred.

Method of identifying a communication protocol to use with a host device by a probe

An apparatus for checking mechanical component parts, such as tools in machine tools, uses optical devices for emitting and receiving a light beam, for example a laser beam, and sensors for detecting the interruption of such light beam. A protection device for at least one of the optical devices includes pneumatic conduits and a nozzle outputting an air stream from a plurality of holes located around the central conduit through which the light beam passes, so generating a tubular shield which embraces the light beam. The protection device further includes a shutter which can be displaced from a rest position, wherein the central conduit is closed and the inside of the protection device is pressurized, to a working position, wherein the nozzle delivers the air stream in the form of a tubular shield. Passing from the rest position to the working position, the shutter assumes an intermediate transit position in which an air blast is outputted through the central conduit for a short time interval. The shutter has cylindrical surfaces and slides inside a shell of the protection device, driven by plane antirotation surfaces, too.
