A three-wheeled leaning passenger vehicle comprises a frame rigidly mounting a passenger seat; a rear wheel rotatably mounted on the frame in a rearward region thereof; a frame-mounted rotary drive cooperatively coupled with the rear wheel for rotation of the rear wheel relative to the frame; and a frame-mounted coast/steer system including two front wheels freely rotatable relative to the frame in a forward region thereof, and a handlebar coupled with the two front wheels for turning the two front wheels in a plane defined by their rotational axes substantially parallel with one another to corner, the vehicle being configured to substantially freely lean left and right in a natural response to a driver thereof in the driver seat steering the vehicle and leaning respectively left and right, and, alternatively or additionally, to have controlled leaning in response to a hydraulically or otherwise provisioned front-wheel suspension subsystem.

Free-to-lean three-wheeled passenger vehicle, power plant controller and body therefor

An optical scanner (100) includes a rotating scanner disk (116) that integrates a multifocal Fresnel fixation lens (114), a Fresnel optical scanner (122, 124), and an angular position encoder (140) into a unitary, inherently aligned, compression-molded component. An individual being identified views through the multifocal Fresnel fixation lens an image of a pinhole (108) illuminated by a light source (104). The multifocal lens is centered on the disk and creates multiple in- and out-of-focus images (180, 182, 184, 186) of the pinhole image. The combined image appears to the individual as a set of circular images (190, 192, 194, 196), one of which is in focus. The images appear concentric when the individual is properly aligned with the disk and associated optics. The Fresnel optical scanner receives IR light from the light source and creates an IR scanning beam (126) when the disk is rotated. IR light reflected by the fundus (12) of the individual returns via a reciprocal path, by way of a beam splitter (112), and into a detector (134) to generate image data. The disk integrates and inherently aligns multiple optical elements, resulting in a 60 percent reduction of optical components relative to prior scanners.

Eye fundus optical scanner system and method

An apparatus and method for identifying individuals through the ocular reflectance pattern from the fundus of the eye. A fixation target is provided for positioning and focusing the eye of an individual along its visual axis, being centered on the fovea of the eye. An infrared source provides a substantially collimated source beam of infrared radiation. A scanner directs the infrared radiation into the fixated eye from a plurality of sequential angularly divergent positions forming a substantially circular locus of points substantially centered on the fovea. The light is reflected in part out of the eye and forms a reflected beam. A detector measures the intensity of the radiation reflected from the eye at each sequential location, the intensities being recorded as an identification pattern. At a later date the eye may be presented again to the apparatus in a different rotational position about its visual axis and another pattern generated. The two patterns will be substantially the same, varying only in the relative start points of the data sequences. One pattern may be rotated with respect to the other pattern to ascertain that the two patterns match, thus verifying the identity of the individual.

Fovea-centered eye fundus scanner

In a method and apparatus for acquiring and recording an identification pattern from the reflectance of the fundus of an eye, a single light source is operable to produce a substantially columnar source beam of infrared light directed into the fixated eye from a plurality of sequential, angularly divergent positions. The light is focused on the retina and reflected in part out of the eye. Variations in the ocular structure contribute to various reflected intensities. The intensity of the reflected light is detected, measured and recorded for each sequential angularly divergent position forming a unique and repeatable identification pattern, or 'signature' for each individual.
