A method of providing support to a user of a computer peripheral includes sensing a peripheral indicia at a computer and registering the peripheral and downloading from a server additional information about the peripheral based on the peripheral indicia. According to specific embodiments, this is accomplished by associating each user with an anonymous token that is decoupled from the user’s identity. The body region has the first conductivity type, and the first electrode region, the second electrode region, and the isolation region have a second conductivity type. The vent unit has valves corresponding disposed on the vents, and a driver for actuating the valve to adjust an opening size of the vent through the valve. The slidable hatch has two opposite sides that define a width of the slidable hatch, the shaped bar extending substantially the full width of the slidable hatch.
