Abstract: A planar antenna comprising: a substrate (10) having opposed first (10A) and second (10B) flat faces; the first flat face comprising a first ground (12), a second ground (14), a feed track (16) there between and an antenna pattern (18) and the opposed second flat face comprising a third ground (20); the third ground being connected to first and second grounds for assuring the continuity of the ground plane with the feeding; and the antenna pattern forms a coil line disposed into the remaining surface of the first flat face and comprises two overlapped loops in such a way that the antenna pattern is substantially auto-complementary.

Abstract: A method of disabling operation of a disposable print module that has an ink reservoir and a plurality of ink ejection nozzles including unused nozzles, and that serves to be mounted on a base of a postage meter, the method including the following steps: forming, in a prior step, a residual ink level counter using a determined first group of the unused nozzles; determining the volume of ink consumed; destroying one of the unused nozzles of the residual ink level counter every time the print module is mounted on a different postage meter base; destroying one of the unused nozzles of ink consumed exceeds a predetermined ink level; and disabling operation of the print module when all of the unused nozzles of the residual ink level counter have been destroyed.
