Abstract: A method for monitoring a function of a safety unit, in particular of a bilge blower of a boat with a combustion engine, connected via a manually operated switch to a voltage supply. The current flowing through the safety unit is measured and an acoustic alarm is triggered, if a sensor voltage derived from the measured current falls below a reference voltage.

Abstract: The present invention provides an improved linerless label printer and an associated method for printing a linerless label wherein the printed label is supported in a cantilevered position by a blanket of air until removal. Linerless labels are those labels that are printed and used without conventional release paper or liners. The labels include a printable surface and an opposed adhesive surface. Various embodiments of the invention are directed to a linerless label printer comprising a platen roller for driving the linerless label from a print position to a removal position, a secondary roller disposed adjacent the platen roller for removing a partially-adhered linerless label from the platen roller, and a flow device for providing an air flow that buoyantly supports the linerless label generally above the secondary roller in the removal position. A backwinding media supply spindle may also be provided to remove partially adhered linerless media from the platen roller during backfeed operations.
