Abstract: An abrasive product has a flexible abrasive area for abrading surfaces to be abraded and comprises: a fabric; a plurality of flexible loops protruding from the fabric towards the flexible abrasive area, wherein each loop is formed by a pair of bottom-half arcs, a pair of legs and a head, wherein the pair of legs connects the pair of bottom-half arcs with the head, the bottom-half arcs of the loops are interlaced in rows in the fabric and form rows of interlaced bottom-half arcs, wherein the legs and heads protrude from the fabric, the heads of the loops are interconnected with one another at a distance to the fabric such that the flexible abrasive area is at a distance to the fabric, and the heads of the loops are at least partially provided with abrasive particles and form the flexible abrasive area.

Abstract: A power tool with a direct current, DC, power source comprising a controller for controlling a driver circuit driving a brushless motor in a power tool, the driver circuit being coupled to a direct current, DC, power source and including a first switching element pair coupled to a first phase winding of the brushless motor and a second switching element pair coupled to a second phase winding of the brushless motor; and the controller being arranged to alternately switch a first switching element of the first switching element pair and a second switching element of the second switching element pair, wherein the first switching element and the second switching elements are coupled to a respective terminal of the DC power source. A power tool comprising such a controller, and a method of controlling a driver circuit driving a brushless motor in a power tool.

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.
