Inventor: NICHOLSON WILLIAM ERNEST
IPC: A63H27/00
Filed: 2001-11-16
Abstract: An apparatus is disclosed for a modular and adjustable autorotative flying toy comprising: a planar, quasi tear-drop shaped wing having a substantially linear leading edge; an elongated cylindrical spine adapted to receive the wing; and a root constructed from elastomeric material, adapted to receive the spine. One end of the spine is inserted into an aperture in the root and fixed there by the root's elastomeric properties. The spine's cylindrical surface has a slit running parallel to its elongated axis from its distal end towards the root. The slit receives the linear leading edge of the wing, securing it relative to the spine and the root. The flight and rotational characteristics of the flyer may be adjusted by interchanging its components for alternative components that have different size, shape or weight. The flight and rotational characteristics of the flyer may also be adjusted by slidably adjusting the wing's position within the slit in the spine. When being used, the device is propelled upward or dropped from a height and autorotates about its center of mass during descent.

Abstract: An apparatus having an insertable portion for holding a position sensor is disclosed. The position sensor can transmit a signal indicative of its position with respect to a field generator. The insertable portion of the catheter has fiducial markings that are detectable by an imaging modality when the insertable portion is inserted into the anatomical body. After the insertable portion has been inserted into the anatomical body, the fiducial markings can be detected to facilitate registration of the position sensor held in the insertable portion to the anatomical body. The apparatus also has a fixing mechanism for releasably fixing the insertable portion to the anatomical body. When the insertable portion is inserted into the anatomical body to a location of interest, the fixing mechanism rigidly fixes the insertable portion of the catheter to a part of the anatomical body near the location of interest. The fixing mechanism can comprise a screw, or, at least one barb. The fixing mechanism can also comprise an inflatable member, such as a lobe, which inflates to fix the catheter in a passageway, while still permitting fluid flow around the insertable portion and through the passageway. The fixing mechanism may also comprise a plurality of moveable fingers having gripping elements such that, in a collapsed configuration where the gripping elements are near the insertable portion, the insertable portion can be inserted into a passageway near the location of interest, and in a deployed configuration, the gripping elements can engage a surface of the passageway, but permit fluid flow around the insertable portion and through the passageway. The apparatus may comprise a catheter, needle or endoscope for inserting the insertable portion.
