Abstract: A throttle position sensor is provided with a plurality of sensing elements which allow the throttle position sensor to provide a high resolution output to measure the physical position of a manually movable member, such as a throttle handle, more accurately than would otherwise be possible. The plurality of sensors significantly increases the redundancy of the sensor and allows its operation even if one of the sensing elements is disabled.

Abstract: A hydraulic damper is provided for a steering system, such as that of a boat or watercraft. A manually movable steering mechanism, such as a steering wheel, is connected to a piston and cylinder combination in such a way that rotation of the steering wheel causes relative movement between the piston and cylinder. Hydraulic fluid is disposed within the cylinder in such a way that movement between the cylinder and piston requires the hydraulic fluid to move from one portion of the cylinder to another portion of the cylinder. This fluid movement is conducted through a conduit which can be external to the cylinder or internal to the cylinder and extending through the piston.

Abstract: A magnet rotor assembly is provided with a nonmagnetic ring, which can be made of an elastomeric material, which has at least one locating protrusion extending radially outward from a first surface of the ring. It also comprises at least one locking protrusion extending radially outward from the second surface of the ring. A plurality of permanent magnets are embedded within the nonmagnetic ring and spaced circumferentially around the nonmagnetic ring. The ring is shaped to be received within a rotatable component of an internal combustion engine, such as a flywheel, which has an internal cylindrical surface. The locking protrusions of the ring are shaped to elastically deflect in a radially inward direction in response to contact between the locking protrusions and the internal cylindrical surface of the rotatable component when the nonmagnetic ring is forced axially into the rotatable component.

Abstract: A personal watercraft has a daytime running headlight that illuminates continuously or stroboscopically when the personal watercraft is operating. The daytime running headlight makes the watercraft more noticeable to other boaters. Several embodiments are shown in which one or more daytime running headlights are mounted to the personal watercraft above the deckline of the watercraft and forward of the handlebars of the watercraft. Such positioning renders the daytime running headlight easily noticeable to other boaters even in relatively choppy water. The daytime running headlights should not only illuminate light forward of the watercraft, but should also illuminate peripherally from the watercraft. A linkage mechanism can be used to turn the one or more headlights in the direction in which the watercraft is turning.
