Abstract
A signal processing means (40) outputs a signal (41) representing a number when a combination of at least two imagers (11), (12) detects a spatial arrangement of a plurality of code portions of a coded data source (60)—where the spatial arrangement of the plurality of code portions represents the number, and where imager combinations can comprise spatial, temporal, and light property combinations.

15. A data acquisition product comprising:
-
a first imager, the first imager having a first imager field of view;
a first coded data source, the first coded data source having a first spatial arrangement of a first plurality of first code portions, the first spatial arrangement of the first plurality of first code portions representing a first number;
first light being detected by the first imager if the first light is from the first imager field of view first coded data source light representing the first spatial arrangement of the first plurality of code portions; and
a signal processor, the signal processor being coupled to the first imager, and the signal processor being adapted to cause a signal which represents the first number if the first coded data source light is in the first field of view and is occluded from the first light detected by the first imager, - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method of acquisitioning data comprising:
-
representing a first number with a first coded data source, having a first spatial arrangement of a first plurality of first code portions representing the first spatial arrangement of the first plurality of code portions with first coded data source light from the first coded data source;
detecting first light with a first imager if the first light is from a first imager field of view;
causing a signal which represents the first number if the first coded data source light is in the first field of view and is occluded from the first light detected by the first imager. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40)
