Wolfram Schilz, Manfred Rahlff, Uwe Jurgen Schmidt, Klaus Gottfried Plass, Eckhard Schroder: Device for reducing the granulation in the transmission of optical information by means of a highly coherent beam of radiation. U S Philips Corporation, Frank R Trifari, Simon L Cohen, March 2, 1976: US03941456 (37 worldwide citation)

A device is described for reducing the granulation during the transmission of optical information with a highly coherent radiation beam. The device includes a first objective system, a radiation-diffusing element disposed in the image plane thereof, a second objective system and a radiation refracti ...

Wolfgang Meyer, Wolfram Schilz: Microwave method for measuring the relative moisture content of an object. U S Philips Corporation, Robert J Kraus, November 30, 1982: US04361801 (28 worldwide citation)

The moisture content of an object is determined by placing the object in a field produced by a microwave applicator and measuring the dielectric properties of the applicator. The measured properties are used to derive the moisture content from known dielectric properties for the applicator without t ...

Burkhard Schiek, Wolfram Schilz, Rolf Jacobson: Microwave range measuring system for measuring the distance of an object. U S Philips Corporation, Simon L Cohen, December 9, 1980: US04238795 (24 worldwide citation)

Disclosed is a microwave range measuring system for determing the distance to an object by means of the phase difference between a transmitted frequency-modulated wave and the wave reflected by and received from the object. The frequency of the transmitted microwave signal is varied between two fixe ...

Wolfram Schilz, Burkhard Schiek: Doppler radar measuring apparatus. U S Philips Corporation, Robert J Kraus, January 28, 1986: US04567484 (9 worldwide citation)

Range-dependent sensitivity of an RF doppler radar apparatus is reduced to prevent false alarms when small objects move in close proximity to the apparatus' antenna. The sensitivity is reduced by periodically FM-modulating the transmitted RF signal at a frequency corresponding to a wavelength which ...
