Abstract:
A wide field of view imaging system (100). The novel system (100) includes a rotating mirror (18) having two reflective surfaces each surface, respectively, reflecting light from a scene to first and second sensors (10, 12) positioned to receive light from the mirror (18), wherein the first and second sensors (10, 12) each occupy a different portion of the volume surrounding the mirror (18). In the illustrative embodiment, the mirror (18) is a flat, double-sided mirror rotating at a constant velocity about an axis parallel with the surface of the mirror (18). The first and second sensors (10, 12) are all-reflective optical systems, with the first sensor (10) opposite the second sensor (12). In the preferred embodiment, the invention further includes third and fourth opposing sensors (14, 16) clocked 90° from the first and second sensors (10, 12). The first and second sensors (10, 12) cover an outer annulus of the field of view while the mirror (18) rotates a first 90°, and the third and fourth sensors (14, 16) cover an inner annulus while the mirror (18) rotates the next 90°.
Abstract:
A release binding (20) is shown for releasably attaching a ski boot to a telemark or cross-country ski (22). A load spool (50) having a circumferential groove (56) is attached perpendicular to the bottom of a standard toe plate (24) used to secure the toe of the boot. A release plate (40) having a planar load spring (44) inside is attached to the ski. The load spring has two sides (62, 64) attached together at both ends forming an elongated aperture. To assemble the boot on the ski, the skier orients the load spool through a hole (48) in the top of the release plate into the elongated aperture of the spring and pushes down. A pilot surface (60) on the load spool pushes the two sides of the spring apart until the groove is reached whereupon the two spring sides snap into the groove retaining the toe plate on the ski. In a preferred embodiment, release binding (320) includes, an adjuster (323) for selectively adjusting release torque, cooperating contours (371) and (373) disposed on adapter plate (321) and central pad (375) respectfully for properly aligning adapter plate (321) with release plate (340), and snow discharge ports (381) located on release plate (340) for moving snow away from load spool (350) and load spring (344).

Abstract:
A release binding is shown for releasably attaching a ski boot to a telemark or cross-country ski having a load spool with a circumferential groove and a substantially elliptical holding portion attached perpendicular to the bottom of a toe plate. A release plate having a load spring with two sides is attached to the ski. To assemble the boot on the ski, a lever is moved to an unlocked position placing the minor axis of the ellipse of the load spool perpendicular to the two sides of the spring. After the boot is assembled to the ski, the lever is moved to a locked position which moves the major axis of the ellipse of the spool until it is perpendicular to the sides of the spring.
