Abstract: A postage meter (franking machine) is provided having a limited number of physical (mechanical) keys associated with frequently performed tasks, and a touch-sensitive display of limited size with regions associated with rarely performed tasks. Optionally a receiving area is provided which can receive a printed sheet, and a touch-sensitive area is juxtaposed with the sheet, permitting user selection of items on the printed sheet. By means of a scrolled display of subsets of a character set, the user may readily create text strings on the touch-sensitive display of limited size. A history is kept of frequently selected print parameters, and the user can scroll through a list derived from the history.

Abstract: A process for measuring parameters of organs and tissues, especially blood flow through an organ, particularly the liver, is based on a medical technology apparatus that can be constructed in modular fashion. The preferred process uses the hydrogen clearance method to determine blood flow. The preferred apparatus includes at least one measuring instrument and at least one measuring or therapy sensor that is detachable from that instrument. Additional connecting elements make it possible to construct an individually adapted measurement array. For a monitoring and checking operation, both the sensors or therapy heads, and the various connecting elements are equipped with electronic code elements which can be systematically read and evaluated by at least one of the measuring instruments used.
