Abstract: Data related to a plurality of medical devices and potential upgrades to the plurality of medical devices is stored. In an upgrade recommender method, a plurality of different potential upgrades are determined for the plurality of medical devices. A set of customer priorities and/or requirements are received. A score is assigned to each potential upgrade based on the received set of customer priorities and/or requirements, and an indication is output of at least the highest-scoring potential upgrade. A compatibility status between multiple medical devices of the plurality of medical devices may also be determined from the data related to the plurality of medical devices, and for the different potential upgrades, and these compatibility statuses displayed.

Abstract: According to an aspect, there is provided a computer-implemented method for providing visual feedback to a user of a rotary shaver. The method comprises (i) receiving movement measurements representing movement of the rotary shaver during a shaving operation; (ii) processing the received movement measurements to determine a representation of a trajectory of movement of the rotary shaver during the shaving operation; (iii) processing the determined representation to project the representation onto a two-dimensional plane; (iv) generating a graphical user interface, GUI, the GUI including the projected representation and a graphical template comprising an annular target zone for a correct circular motion of the rotary shaver during the shaving operation; and (v) displaying the generated GUI using a display unit.
