Appl. No.:

10/318558

Inventors:

Don W. Lee - Glendale CA, US
Chung H. Lee - Glendale CA, US

International Classification:

A61F002/06

US Classification:

623 111

Abstract:

A method and apparatus for introducing a stent into a region of a major blood vessel within the human body in a manner which substantially reduces the risk of embolic material escaping to the vessel and causing a blockage at a downstream location. Additionally, the apparatus includes a uniquely designed stent delivery catheter having a central lumen through which a guide wire travels, the central lumen being provided with a valve means that is operable by the guide wire and when moved into a closed position by withdrawal of the guide wire, functions to prevent the flow of loose debris toward the proximal end of the catheter.

Abstract:

A freeflex sports cap is used for sports and physical activities so that it can help people concentrate and focus. The cap is capable of fitting wearers having a range of different head sizes at ease and out of harms way from hurting the wears head. Most importantly, the freeflex sports cap is water resistant; making it a valuable head protective gear during any unexpected weather changes. The cap includes a multi gore shell that forms the crown portion and a bill that connects to the crown. The freeflex sports cap is configured to cover the wearers head with the improvement being made along the base of the cap that gives a unique stretch along the cordial axis to fit multiple head sizes and providing maximum head comfort. The cap has the looks and appeal of a fitted cap where the size of the fitted cap is already predetermined and measured accordingly. Moreover, the freeflex sports cap doesn't require an adjustable fastener portion or an open portion on the back of the cap. The greatest advantage to the freeflex sports cap is that it is capable of providing the wearer a custom fitting cap within a predetermined range of head sizes, without creating a change in shape due to the difference in head size or provide any discomfort and pain during any circumstantial changes in weather.

8/570355

Inventors:

Chung N. Lee - Los Angeles CA

International Classification:

G02B 702

US Classification:

359819

Abstract:

Transparent acrylic lens elements can be screwed into drilled holes in the display sheet of an interiorly lighted sign box, to form illuminated messages. Each lens element has an enlarged head, and a cylindrical shank fitting into one of the drilled holes. A helical wall extending around and along the shank, so that the lens element can be rotated for screwing the element into the drilled hole. The helical wall has parallel flat side surfaces adapted to exert frictional grip forces on the associated display sheet, so that the lens element can be inserted partway into the hole to achieve different spacings of the enlarged head relative to the display.

Abstract:

A navigation method is provided and includes: deploying a plurality of stations about a geographic area; providing the automated guided vehicle in the geographic area; transforming a position of each of the stations into a coordinate in a map; receiving a task command by the automated guided vehicle that includes an end station from one of the plurality of stations to be reached; retrieving a path parameter; identifying a start station as the closest station to the automated guided vehicle; calculating a traveling route connecting the stations by the processor of the automated guided vehicle in an order from the start station to the end station; determining whether a physically marked line has been detected, if no, controlling the automated guided vehicle to travel along the traveling route and along the moving path from one of the stations to one another of the stations with reference to the path parameters.
