Abstract: A putting practice device has a bottom support, side supports, a front plate, and a cover. The side supports are attached at opposed ends of the bottom support. Each side support has a top edge with a horizontally disposed sliding track. A front plate has a face that defines at least a portion of a desired travel path of a putter head. A cover has sliders that engage the sliding track of the side supports and the central support such that the top plate is slideably connected to each side support and to the central support. The cover has an extended portion that extends past the front plate and covers the at least a portion of the desired travel path. The position of the extended portion is adjustable by sliding the sliders along the sliding tracks.

Abstract: A hand-held music-creation device has a plurality of stored samples of sound. The device has an interface comprising a grid, where the rows represent channels in which samples may be selected and the columns represent loop measures. The device allows the user to select which samples are to be played in a given loop measure. A loop is created by assigning samples to available loop measures. The user may hear the resulting composition, comprising a loop repeating indefinitely. Each device may be connected to at least one other device to form a system. The system allows the creation of a longer loop and/or allows an increase in sample selection for each loop measure in the loop.
