摘要:
A method for testing an electronic circuit is described, in which the actual state of circuit components which have previously been activated on a test basis after an initial initialization is compared with a setpoint state. Of the circuit components to be tested, essentially only those circuit components are operated simultaneously which, under the given circumstances, can be expected to interact in the context.

The present invention relates to a device for electronically surveying items in a monitored area. The device is equipped with a transmitting and/or a receiving device. The aim of the surveying device is to provide an economical way for surveying electronically protected items. To this end, the surveying device is made up of individual layers of material, which taken individually are flexible and possessed of a low level of resistance, but when combined are characterized by a high level of rigidity and resistance.

To conserve relatively expensive printing ribbon, in particular a thermal transfer ribbon, when a portion of the medium which is not to be printed, e.g. the space between two labels, passes through the printing area, after the end of the printing process for a first label or similar item, the thermal transfer ribbon is stopped, and simultaneously the application force of the print head, in particular of the thermal print head, against the counterpressure roller is neutralized, and when the next label or similar item to be printed arrives in the printing area, the pressure on the thermal print head is reactivated, and simultaneously the advance of the thermal transfer ribbon is resumed, whereby the controlled stopping of the thermal transfer ribbon is accomplished by means of a stopping device which stops the first spool from which the ribbon is unwound, and by means of a slip clutch which makes possible the simultaneous stopping of the second spool which winds up the ribbon, in spite of the fact that the drive motor continues to run.
摘要:
A portable printer is disclosed in which the printer comprises a housing; a printing unit; means for supplying to said printing unit a substrate onto which indicia are to be printed; and means for inputting data to control the nature of the indicia printed at said printing unit, characterized in that said housing includes a main frame which serves to support the functional components of the printer; and a protective housing which fits over said frame.
