Stabilization apparatus (12) for a watercraft (10) having a hull (14), including at least one hydrofoil (20) with a leading edge (22) and a trailing edge (24), the edges defining a chord (26) extending therebetween, the at least one hydrofoil being mounted below an underside of the hull and arranged for rotation about an axis (30) that is generally perpendicular to the chord and directed towards the underside (28) of the hull, and control apparatus (40) that rotates the at least one hydrofoil about the axis in response to roll of the watercraft so as to stabilize the watercraft against the roll. Preferably the axis passes generally through the chord's center.
摘要:
This invention is an instrument for seizing walls of a body cavity including a first portion (22) and a second portion (30), the second portion being insertable into the cavity and being reversibly deformable from a first (FIG. 5A) to a second (FIG. 5B) configuration while inside the cavity, the first portion being operative to reversibly deform the second portion from the first to the second configuration, the second portion when in the second configuration being operative to seize the walls of the cavity.
摘要:
A non-intrusive monitoring optical connection between two fiber optic lines including a sending fiber optic end that emits light to a first lens that collimates the light to a larger diameter parallel beam of light that enters a tunnel, a second lens that focuses the light from the tunnel to an end of a receiving fiber optic line, a mirror disposed in the tunnel between the first and second lenses, which reflects and diverts part of the parallel beam of light to a diverting tunnel, and a second diverting mirror, disposed at a non-zero angle to a longitudinal axis of the diverting tunnel, which directs the beam from the diverting tunnel into a second diverting tunnel wherein it is collimated by a third lens, disposed in the second diverting tunnel, to an end of a monitoring fiber optic line.
摘要:
A piezoelectric motor including a rotor, a stator including a piezoelectric material having axial polarization, the stator including at least three pairs of electrodes spaced from one another on a top end face thereof and a common electrode on a base end face thereof, and slabs affixed to the stator at spacings between the electrodes, wherein the rotor is pressed towards the slabs by a pre-load force, wherein when a positive charge is applied to a first of the electrodes and a negative charge is applied to a second of the electrodes and an electric common port is applied to the common electrode, D33 piezoelectric phenomenon is created, thereby causing the spacings between the electrodes to bend and the slabs to tilt, thus applying a frictional pushing side force against the rotor to cause the rotor to rotate.
