Claim:
1. A touch-sensitive apparatus, comprising: a panel defining a touch surface; and opposite rows of components connected for energy exchange with the panel at opposite ends of the touch surface, each of the components being a first type of component or a second type of component, the first type of component configured to emit energy as a diverging beam, and the second type of component configured to detect energy, each of the opposite rows including an arrangement of consecutive component blocks, each component block including only components of the first type or components of the second type, and each component block defined by a type value and a number value, the type value indicating the type of components in the component block, and the number value indicating the number of components in the component block; wherein each of the opposite rows includes a respective sequence of two component blocks of different types, and each of the opposite rows is defined by systematically repeating the respective sequence along the respective opposite end; wherein the two component blocks in the sequence included in one of the opposite rows have different number values; wherein at least one component block differs between the sequences included in the opposite rows; and wherein the opposite rows define a grid of transmission paths that extend across the touch surface from the components of the first type to the components of the second type, each of the components of the second type configured to detect energy on a set of transmission paths that extend from at least two of the components of the first type.
