Compact, long-range absolute position transducer with an extensible compact encoding

摘要: A compact, long-range inductive absolute position transducer system has two members movable relative to each other and includes a code track at least one fine wavelength transducer. The include read head member scale member. phase difference between the angles of transducers may be used generate an intermediate wavelength. Alternatively, sequential n-bit words. Each word identifies with respect first resolution. integer number words greater than or equal one. Using this relationship, is identify start (start bit) appropriate word. then define second, finer
