Abstract: A method for controlling operation of an abrading system (500) comprises: —providing an abrading head (300), which comprises an abrading device (200) and a communication unit (MOD1), —providing parameter data (PAR1) associated with the abrading device (200), —storing the parameter data (PAR1) into a memory (MEM2) of the communication unit (MOD1), —transporting the abrading head (300) to an abrading site (SITE1), —electrically connecting the abrading head (300) to a driving unit (400) at the abrading site (SITE1), —transferring the parameter data (PAR1) from the communication unit (MOD1) to the driving unit (400) at the abrading site (SITE1), and —driving an electric motor (MOTOR1) of the abrading device (200) with the driving unit (400) according to the parameter data (PAR1).

Abstract: A trigger apparatus for a powered device, such as a power tool is disclosed. The powered device comprises a trigger operable by a user to move from a first position to at least one second position so as to control an operation of the powered device. The trigger apparatus comprises: a linear Hall effect sensor for measuring a change in a magnetic field associated with the trigger being moved from the first position to the at least one second position, and configured to generate a sensor signal based on the measured magnetic field, for controlling the operation of the powered device; a power module configured to power, the linear Hall effect sensor, upon reception of an activation signal for indicating that the trigger apparatus is to be activated; and an activation switch configured to generate the activation signal, when the trigger is moved from the first position. A powered device comprising the trigger apparatus and a method of controlling an operation of a powered device are also disclosed.

Abstract: The disclosed solution comprises a device for changing abrading products (30), the device (1) comprising a detacher (2) comprising a table (10), a blade (14) adapted to penetrate into between an abrading product (30) and the gripping means (34) of the abrading tool (4), and means (16, 18, 19) to co-planarly adjust the mutual distance (d) between the table (10) and the blade (14) to correspond to the thickness (t) of the abrading product (30) in the absence of the abrading product (30).
