Patent number: 7973916Abstract: Apparatus and methods for detecting inclination employ a point source of light from which light is emitted through a lens toward a reflective surface of a liquid contained in a vessel. Light reflected from the surface passes through the lens to form a defocused image of the point source on a two-dimensional array of detector elements. Data acquired from the array represents intensity of the light incident on each of the detector elements. A center of gravity representing inclination of the vessel is determined from the data.Type: GrantFiled: February 14, 2010Date of Patent: July 5, 2011Assignee: Trimble Navigation LimitedInventor: Andreas Glimm

The entire length scale or angle scale is divided into n graduation portions of equal length, wherein every portion contains a sequence of transparent and non-transparent marks, and the sequence is successively a number which is binary-coded with k bits and correlated with the respective portion as rough value code and a fixedly recurring number which is likewise binary-coded with k bits as a reference mark (reference mark with length of k bits). Every code bit is of equal length and is formed of a transparent and a non-transparent field (half-bit) of equal length, wherein the binary information comes from a sequence of two half-bits.Type: GrantFiled: August 18, 2000Date of Patent: August 27, 2002Assignee: ZSP Geodaetische Systeme GmbHInventor: Andreas Glimm
