Abstract: Information related to art is provided in networked computing environments wherein users can participate in public or private online interactive video conferences, chat rooms and other online sessions led by art galleries or art gallery affiliates. User's may switch between public sessions and private sessions when ready to make a transaction related to an art object or artist presented in a public session. In private online sessions, potential consumers may also electronically provide the art gallery pictures, diagrams and photographs of an area in which they are interested in placing certain art objects. An image of the art object is shown within the picture to scale with other objects such as a wall, and angle of view. Users may also see the art objects to scale next to other stock images of familiar reference objects during the online session.

Abstract: A security sealing system providing tamper detection. Including a self locking flexible material strip bearing indicia and an electronic system. The electronic system includes at least a transponder, having two separated subunits. The transponder is accessible when intact by a wireless reader means, indicating the intactness of said transponder and reading the transponder's memory.

Abstract: A flipper-type swimming propulsion aid assembly for attachment to the feet of a swimmer to increase the swimmer's effective foot area. The swimming aid for each foot includes a collapsible frame of generally isosceles triangular configuration having side frame members of substantially equal length which are pivotally joined through a heel plate at the heel end of the frame and a foldable cross frame member joining the toe ends of the side frame members. The swimming aid also includes a fabric or plastic sheet web component which is placed over the collapsed frame assembly and thereafter the side frame members are separated with the cross frame member opened and extended. The web component is provided with mating attachment straps affixed to the toe end of said web component and positioned to be wrapped about the cross frame member to maintain such member's open and extended orientation.

The swimming aid for each foot includes a collapsible frame of generally isosceles triangular configuration having side frame members of substantially equal length which are pivotally joined through a heel plate at the heel end of the frame and a foldable cross frame member joining the free or toe ends of the side frame members. The swimming aid also includes a fabric or plastic sheet web component which is placed over the collapsed frame assembly and thereater the side frame members are separated with the cross frame member opened and extended.

Abstract: A flipper-type swimming propulsion aid assembly for attachment to the feet of a swimmer to increase the swimmer's effective foot area. The swimming aid for each foot includes a dismantlable frame of generally isosceles triangular configuration having side frame members of substantially equal length which are pivotally joined at the heel end of the frame and at least two cross frame members of progressively greater length adapted at their ends for removable joinder to the side frames with the longest of the cross frame members joining the free ends of the side frame members. The swimming aid also includes a fabric or plastic sheet web component for the frame with the web component being of generally isosceles triangular configuration matching the configuration and size of the frame and including side loops for receiving and maintaining the side frame members and including cross loops for receiving and maintaining the cross frame members.

Abstract: A supplemental propulsion device for a sailboat or sailboard type water craft including a pivotal centerboard. A pair of propulsion wings that are vertically hinged to one-another and mounted to the lower portion of the leading edge of the centerboard of the craft. Upon the application to the centerboard of a reciprocating pumping action each propulsion wing moves inwardly to a retracted position adjacent the centerboard during forward movement of the lower portion of the centerboard and moves outwardly to an extended position removed from the centerboard during rearward movement of the lower portion of the centerboard. Cables connect the free edge of each of the propulsion wings to the trailing edge of the centerboard to stop the outwardly movement of the wings at a point no more than 90.degree.

Abstract: A swimming propulsion aid for attachment to the feet of a swimmer. The assembled swimming aid for each foot includes a foot wing strapped to the foot of the swimmer so as to extend from the inner edge of the foot laterally under the foot sole and outwardly therefrom to provide an enlarged and effective thrust area for pushing action with respect to surrounding water during the leg extension portion of a reciprocating leg stroke by the swimmer. The foot wing may be constructed of a generally rectangular frame member over which is stretched a flexible sheet of fabric or plastic material or constructed of a generally rectangular frame member across which are aligned a multiplicity of parallel louvers pivotal to a closed position during the leg extension portion of the reciprocating leg stroke by the swimmer.
