Abstract: The present specification relates to an air treatment device and a detachable sensor module. The air treatment device comprises a user interface configured to display, for selection by a user, at least one static or open-loop operational mode to be executed by a controller; and a wall comprising one or more pervious sections towards an ambient volume. One side of the wall comprises a connector for mating with a corresponding connector of the detachable sensor module, and the connector, when the sensor module is present, enables a data connection from the sensor module to the controller. When the data connection is enabled, the user interface is configured to display at least one closed-loop operational mode, in which the controller controls the air treatment section in response to measurement data relating to the ambient volume received from the sensor module.

Abstract: An air treatment device (200) and a detachable sensor module (100). The air treatment device includes a user interface configured to display, for selection by a user, at least one static or open-loop operational mode to be executed by a controller; and a wall including one or more pervious sections towards an ambient volume. One side of the wall includes a connector for mating with a corresponding connector of the detachable sensor module (100), and the connector, when the sensor module is present, enables a data connection from the sensor module to the controller. When the data connection is enabled, the user interface is configured to display at least one closed-loop operational mode, in which the controller controls the air treatment section in response to measurement data relating to the ambient volume received from the sensor module.

Abstract: An orbital machining apparatus for producing a hole in a workpiece using a cutting tool and including a first actuator for rotating the cutting tool about its longitudinal center axis, a second actuator for moving the cutting tool in an axial feed direction, a third actuator for rotating the cutting tool about a principal axis and a radial offset mechanism. The radial offset mechanism includes an inner cylindrical body having an eccentric cylindrical hole and which supports a spindle unit, the inner cylindrical body radially supported in an eccentric cylindrical hole of an outer cylindrical body to adjust the radial distance of the cutting tool longitudinal center axis from the principal axis. The third actuator includes first and second motors which rotate the outer and inner cylindrical bodies, respectively, in synchronism to maintain a mutual rotary position thereof to keep a cutting tool radial offset position unchanged during operation.

Abstract: An orbital machining apparatus for producing a cylindrical or conical hole in a workpiece includes a cylindrical cutting tool. The apparatus includes a radial offset mechanism configured for controlling the radial distance of the center axis of the cutting tool from a principal axis, the principal axis being substantially parallel to the center axis of the tool and coaxial with a longitudinal center axis of the hole to be machined.
