A calibration apparatus calibrates cross-frequency phases of large-signal network analyzer measurements and includes: a signal generator; a vector network analyzer that includes couplers and receivers that receive the calibration signal and the reference multitone signal from the signal generator; a calibration receiver that receives a calibration signal from the vector network analyzer and produces a digitized calibration temporal signal from the calibration signal; and a signal processor in communication with the signal generator and the vector network analyzer and that: receives the reference digitized signal from the reference receiver; receives the forward digitized signal from the forward coupled receiver; receives the reverse digitized signal from the reverse coupled receiver; receives the digitized calibration temporal signal from the calibration receiver; and produces a calibration factor from the reference digitized signal, the forward digitized signal, the reverse digitized signal, and the digitized calibration temporal signal.

Calibration apparatus and calibrating cross-frequency phases of large-signal network analyzer measurements

Systems and methods are described for a non-contact method for positioning a tip of an object. A light beam of known dimensions is projected and a position of the tip of the object relative to the light beam is adjusted. Light scatter indicative of the tip of the object being positioned within the dimensions of the light beam is detected and a position of the tip of the object is determined based at least in part on the known dimensions of the light beam and the detected light scatter.

Non-contact systems and methods to locate sharp tips

With the advent of the protective shoelace storage compartment incorporated within the new designs of the sports footwear, the shoes will appear less cluttered with the bow and lace ends concealed or all the laces, the bow and lace ends concealed. Without the laces dangling those individuals engaged in active sports like skateboarding will not have to worry about the laces of their shoes getting tangled in the wheels of the skateboard. The shoelace storage compartment may be closed by means of a zipper on the preferred embodiment or the hook loop fastening means on the alternate embodiment. The novelty of this invention is the added benefit of the concealed storage compartment for articles like identification, driver's license or money for those in sportswear not having any pockets or those traveling where additional precautions are necessary.
