Abstract:
1. A positioning cap comprising: at least one semirigid telescopic structure forming at least one loop, the semirigid telescopic structure capable of extension and compression while maintaining even spacing of devices selected from the group consisting of optodes and electrodes attached thereto; wherein the semirigid telescopic structures comprise a plurality of telescoping subassemblies, each telescoping subassembly comprising a plurality of links and pivots with a first sub-portion between a first pivot and a second pivot of that subassembly, and a second sub-portion between the first pivot and a third pivot of that subassembly, and wherein a plurality of devices selected from the group consisting of optodes and electrodes serve as the first, second, and third pivots of the telescopic structures; and wherein adjustment of a distance between the first and second pivot of each subassembly mechanically determines a distance between the first and third pivot of that subassembly; and an elastomeric tensioning device configured to tighten the semirigid telescopic structure around an object.
