Abstract: A light weight aerodynamically efficient cycling trailer having a single wheel is provided for towing behind a bicycle or motor cycle. The disclosed cycling trailer includes a body enclosure, an overlying lid, a light weight frame, the first end of the frame bending upwardly along the forward surface of the body enclosure to engage with a removable goose-neck tongue, the goose-neck tongue extending upwards along and attaching to the forward surface of the body enclosure, the forward end of the goose-neck tongue extending over the rear wheel of the bicycle and being coupled to a latching universal joint which couples the cycling trailer to the bicycle. The latching universal joint facilitates the easy connecting and disconnecting of the cycling trailer to a bicycle without the need of additional attachments. The cycling trailer is also provided with a removable child carrier, a hanging bar and a cargo shelf.

Abstract: Disclosed is a tunable damping system for use in reducing vibrations associated with metal cutting and tooling. The tunable damping system may be located in a boring bar, an end mill, a modular tool section or the spindle/tool holder of the metal cutting machine. The tunable damping system incorporates a damper mass, elastomeric supports, and a means to lock the mass so as to determine tuning parameters. A tuner assembly consists of sensors and a microprocessor capable of recognizing the most dynamically flexible mode of vibration. The tuner assembly is also capable, through signal processing and microprocessor controlled algorithms, to direct the operator in implementing the proper tuning adjustments of the tunable damping system.
