Golf Technique Improvement Aid Trains for Proper Club Alignment Throughout the Swing

A former professional golfer and University of Wisconsin-Green Bay graduate has developed a novel training aid that improves golf performance by keeping a golfer’s arms and club aligned properly throughout the swing. This innovative tool attaches to a golf club and can be adjusted to fit users with varied grip styles and forearm sizes. It is designed with a unique offset hinge system that enables the golfer to experiment with a continuous range of variations in the arm-to-club relationship during the swing and gives feedback when incorrect motion occurs.

Food & Drug Safety: Time-Temperature Indicator for Perishables

UW–Madison researchers have developed nanoreactors that can detect exposure of a perishable good to an undesired temperature. The device comprises a metal precursor in a stabilizing carrier such as gelatin or chitosan. Upon exposure to heat, the metal precursor forms nanoparticles that can be detected visually or spectroscopically by a change in color, peak wavelength or peak absorbance, as well as the size, number or shape of the nanoparticles that form. The nanoreactors could be applied to product packaging and ‘switched on’ to begin temperature tracking.

Bike Trailer Folds for Easy Storage

UW–Madison researchers have developed a new bicycle trailer design that stays attached while folding for easy storage. The trailer folds and pivots to align with the frame, allowing the user to store his/her bike effectively in a rack, apartment or tight space. The user can go from carrying a backpack, athletic bag or groceries to storing the entire bike/trailer setup in the same area the bike would occupy normally.

The trailer, which attaches to the fork rather than the axle, folds by pivoting up and forward to rest nearly on the seat, sides folded down. When folded it rests in a width thinner than the bike’s handlebars and extends only a few inches beyond the back tire.
