US Patent:

7040443, May 9, 2006

Filed:

Aug 4, 2003

Appl. No.:

10/634579

Inventors:

David Roth - Los Angeles CA, US
Lawrence Diener - Long Beach CA, US
David R. Goetz - Los Angeles CA, US

Assignee:

Go Sporting Goods, LLC - Rowland Heights CA

International Classification:

B62M 1/20

US Classification:

180221, 180220, 180 651, 180 685

Abstract:

A scooter having a fuselage with a front portion and a rear portion that includes a rear wheel rotatably mounted at the rear portion. The scooter also includes a standing platform supported by the fuselage for supporting a rider and a transmission system mounted under the standing platform in the rear portion of the fuselage. The transmission system having a motor with a wheel engagement element being operatively coupled with the rear wheel to allow the wheel engagement element to rotate the rear wheel when the wheel engagement element is engaged with the rear wheel. Another embodiment of the transmission system includes a motor, a first drive cone coupled the motor; and, a drive cone engagement mechanism configured to allow the first drive cone to be operatively coupled with a wheel to rotate the wheel.

Abstract:

Methods and devices for a fully automated synthesis of radioactive compounds for imaging, such as by positron emission tomography (PET), in a fast, efficient and compact manner are disclosed. In particular, the various embodiments of the present invention provide an automated, stand-alone, hands-free operation of the entire radiosynthesis cycle on a microfluidic device with unrestricted gas flow through the reactor, starting with target water and yielding purified PET radiotracer within a period of time shorter than conventional chemistry systems. Accordingly, one aspect of the present invention is related to a microfluidic chip for radiosynthesis of a radiolabeled compound, comprising a reaction chamber, one or more flow channels connected to the reaction chamber, one or more vents connected to said reaction chamber, and one or more integrated valves to effect flow control in and out of said reaction chamber.
