20090090786 | Segmented circular bar code - A segmented circular bar code is made-up of inner and outer locator rings, one or more data rings, two large orientation cells, an even number of radially-extending gaps dividing the bar code into a corresponding number of segments, and gap locator cells straddling each radially-extending gap. Each of the locator rings and the data rings is circular and has a finite width. All rings are concentric and there is no circumferential space between the rings. | 04-09-2009 |
20090289124 | Concentric-Ring Circular Bar Code - A circular bar code includes at least one circular data ring having a plurality of data cells arranged side-by-side in a circle, a circular locator ring of a solid color and conveying the location and size of the bar code to a reading device; and a locator cell conveying the orientation of the bar code to the reading device. The locator ring and the at least one data ring have a finite width, and are concentric, without any gap between adjacent rings. The locator ring can be either inside or outside of the at least one data ring. The locator cell is defined by a gap in the locator ring and a single data cell located in a data ring adjacent the locator ring. The circumferential and radial dimensions of the locator cell convey the data cell size to the reading device. | 11-26-2009 |
20090312961 | Multi-format,binary code symbol for non-linear strain measurement - A binary code symbol for non-linear strain measurement that can be constructed in any geometric shape having a solid, continuous perimeter containing straight line segments. The symbol includes finder cells to “orient” the symbol in order to associate strain measurements with physical dimensions; and contains encoded data in “data regions” and/or “utility regions.” The data and utility regions can be distinct and separate, combined, exclusive (i.e. data regions and no utility regions, or utility regions and no data regions), or omitted. The data “density” can be varied depending upon the application, by varying the number of distinct data or utility cells present in the data regions or utility regions. | 12-17-2009 |
20100072288 | Augmented binary code symbol - An augmented binary code symbol (100) includes a perimeter, first and second data regions ( | 03-25-2010 |
20100139412 | DIFFERENTIAL NON-LINEAR STRAIN MEASUREMENT USING BINARY CODE SYMBOL - The bands and corners of rectangular or other geometric shapes for binary code symbols are used to measure non-linear and non-uniform strain in a material with an anomaly such as a crack in the area of strain measurement. In particular, they can be used to evaluate differential strains in the regions of the bands and corners; and the external and internal boundaries can be used to measure differentials in strain between the external boundaries and internal boundaries. | 06-10-2010 |
20110049250 | Nested binary code symbol - A nested binary code symbol (200) comprising a boundary binary code symbol ( | 03-03-2011 |
20120185182 | TWO DIMENSIONAL BAR CODE HAVING INCREASED ACCURACY - A two-dimensional matrix code containing dark and light square data modules, and a finder pattern of two bars of alternating dark and light square data modules on the perimeter of the symbol for indicating both orientation and printing density of the symbol, wherein all of the data modules are the same dimension and data is encoded based on the absolute position of the dark modules within the matrix, and inner and outer bars are provided along adjacent sides of the matrix code symbol, each bar having a width equal to the square data modules. In one embodiment, the inner and outer bars are solid. In another embodiment, the inner solid is bar and the outer bar is an encoding bar. | 07-19-2012 |
20130094013 | Nested Binary Code Symbol - A non-linear strain gage includes a target for association with an object for which at least one of strain and fatigue damage is to be measured, a sensor, and a computer. The target incorporates a nested binary code symbol for perimeter-based deformation and strain analysis and emits a detectable physical quantity. The binary code symbol includes a boundary binary code symbol having a perimeter constructed of line segments and at least a core code symbol that provides encoded data. The core code symbol is nested within and concentric with the boundary binary code symbol. A method of measuring strain on an object directly using the non-linear strain gage is also provided. | 04-18-2013 |
