Abstract: Thermal camera assembly (1) comprising a thermal imaging detector (3) providing thermographic images and/or recordings, a protective casing (2) which houses the thermal imaging detector and includes a window (5) with a transparent screen (6), one or more sensors (15;16;20;32;33) arranged in the protective casing and providing signals indicative of a physical quantity or a state, one or more actuators (8;22;28) arranged in the protective casing, and a control unit (9) which is integrated in the protective casing. The control unit is directly connected to the thermal imaging detector to receive the thermographic images and/or recordings and transmit them to the outside, to the sensors to receive the relative signals, and to the actuators to control the latter according to the signals received. The control unit is able to manage and control the communication between all the components of the thermal camera and the outside.

Abstract: An apparatus for checking mechanical parts such as tools on machine tools employs optical devices for emitting and receiving a light beam, for example a laser beam, along a checking direction, and sensors for detecting variations in the features of such a light beam. A protection device (15) for at least one of the optical devices comprises a support element (21,22) with an inner seat (20), communication conduits (18,26,34) aligned along the checking direction and a shutter (44) movable, in the internal seat, from a rest position to an operative position of the apparatus. The shutter comprises a transversal through hole (60) which is arranged along the checking direction in the operative position, aligned with the communication conduits to allow the light beam to pass through. A movable closure element (55), for example a small sphere or ball, is arranged in a transversal hollow (54) of the shutter and is pushed by a spring towards the outside of the transversal hollow.
