Patent number: 4731769Abstract: A central operating input and information output system for the control of a plurality of optional instruments in a vehicle has a display for displaying information and an option menu. A first control input controls the functions of the optional instruments and selects the option menu from a basic menu. The option menu indicates the functions of the optional instruments controllable by the first control input. The system has a second control input which controls at least one optional instrument and accesses at least one basic function of the system, irrespective of the option menu currently selected. This allows a central operating input and information output system to have a favorable ergonomic design, to be operated simply, and require a minimum of space.Type: GrantFiled: April 14, 1986Date of Patent: March 15, 1988Assignee: Dr. Ing. h.c.f.

Patent number: 4329055Abstract: An interferometer system for measuring the wavelength of laser light or and other optical radiation comprises an interferometer with a radiation input for a reference beam of a given wavelength, a sample radiation input for a sample beam of unknown wavelength, and a beam splitter for splitting up an incoming beam into two part-beams, and a system for changing the optical lengths of two part-beam optical paths as used by the reference beam and, parallel to it, the beam whose wavelength is to be measured. There is furthermore a detector for converting output beams from the interferometer into representative electrical signals and a signal processing circuit coupled to the detector means.Furthermore in the part-beam paths there is an optical part in the form of a parallelepipedic transparent body able to be rotated for the changing of the lengths of the paths of the beams in relation to each other, and a reflector system for reflecting back the part-beams, coming from the turning part, back into themselves.Type: GrantFiled: February 4, 1980Date of Patent: May 11, 1982Assignee: Max-Planck-Gesellschaft zur Foerderung der Wissenschaften e.V.Inventors: Fritz-Peter Schaefer, Jan Jasny
