Patent number: 5870035Abstract: An instrument panel for co-operation with a microprocessor storing selectable functions and selectable numerical information, comprises a knob (2'), a first switch (3'), an alphanumerical indicator (1'), and a second switch (4'). The knob (2') is rotatable to, in a first operating mode of the microprocessor, select a desired function and, in a second operating mode, selected the desired numerical information. By means of the first switch (3'), the selected function is accepted, the microprocessor is transferred to the second operating mode, the selected numerical information is accepted, and the microprocessor is returned to the first operating mode. The alphanumerical indicator (1') displays both the selected functions and the alphanurnerical information. By means of the second switch (4'), a selection is discarded and the microprocessor is returned to the first operating mode.Type: GrantFiled: June 6, 1997Date of Patent: February 9, 1999Assignee: Pharmacia Biotech ABInventor: Olle Bjernulf
