ABSOLUTE POSITIONS DETECTORS |
| 摘要 |
Example apparatus for absolute position detection are disclosed. An example apparatus includes a housing and digit gears coupled to the housing to rotate about respective parallel axes. Each digit gear has a first portion including a first set of teeth disposed about an entire circumference of the first portion and a second portion including a second set of teeth disposed about only a portion of a circumference of the second portion. Each digit gear is to correspond to a respective digit in a code representing an absolute position of a shaft. A respective idler gear between each adjacent pair of the digit gears is to be intermeshed with the first set of teeth of one of the digit gears and the second set of teeth of the other one of the digit gears. |
