Methods for reducing dimensionality of hyperspectral image data having a number of spatial pixels, each associated with a number of spectral dimensions, include receiving sets of coefficients associated with each pixel of the hyperspectral image data, a set of basis vectors utilized to generate the sets of coefficients, and either a maximum error value or a maximum data size. The at least one polymer may include an elastomeric polymer and a filler polymer, at least one of which contains a silane group. A variety of means for attaching the device to a golf club and for adjusting the position of the device relative to the golf club shaft are also disclosed.
