An LED light source produces a narrow beam of light having a linear field of illumination, which is substantially uniform across the linear field. The light source comprises at least one light emitting diode (LED) and preferably a plurality of LEDs, an optical element for the efficient collection of energy radiating from the LED or LEDs, and an optical element for distributing the collected energy into the linear field of illumination. The apparatus also includes a device or heat sink for thermal management. One or more electronic control circuits are coupled to the LED or LEDs to variably and selectively control them. When a plurality of LEDs are used, the colors produced by the LEDs may different so that the light source is collectively controllable to provide a range of optically mixed colors.

The invention provides improved multi-fiber, fiber optic probe assemblies in which the component parts are adapted for rapid assembly with precise alignment. Some embodiments are adapted to illuminate and collect light from a sample at a particular depth while minimizing interference arising from within the probe assembly itself. Also provided are methods for manufacturing the probe assemblies and optical apparatuses including the probe assemblies.

A therapy apparatus to restore range of motion to joints and limbs. The apparatus is useful for elbow joints and includes a beam on which the elbow joint rests. A tension cord extends through and beyond the length of the elongated hollow beam with a handle at the distal end of the tension cord to be grasped by the user. The proximal end of the cord is pulled by the user's other hand to rotate the elbow. A ratchet clamp forming a part of the beam retains the tension on the elbow. Since it is a ratchet clamp, the cord may be freely pulled in the proximal direction to impart more tension to the elbow, but to release the tension, the ratchet clamp must be disengaged manually. The beam has segments that are telescopically extendable and retractable to accommodate limbs of different lengths and for portability and storage.

A fiber optic probe assembly which incorporate a series of graduated shaped and nestable members, e.g. cylindrical annular members which enable uniform and repetitive construction and assembly of the probes resulting in a high degree of quality control.

A boat having at least two hulls with an adjustable frame which maintains the relative separation of the hulls. Each hull having one or more buoyancy sections. Each buoyancy section of each hull may be relocated laterally, by expansion or contraction of an adjustable frame which causes the relative separation of corresponding buoyancy sections to be controllably adjusted. Accordingly, both deck area of the boat and its stability are increased when the buoyancy sections are extended laterally.

In an aspect, an illumination system (100) is disclosed to comprise a light source (102) configured to generate a light beam (103), and a chromatic reflective unit (1) for being illuminated by the light beam (103). The chromatic reflective unit (1) comprises a plurality of non-coplanar reflective surface sections (3′), and a chromatic diffusing layer (5) comprises a plurality of nanoparticles (37) embedded in a matrix (39), wherein the chromatic diffusing layer (5) is provided upstream of the plurality of reflective surface sections (3′) such that at least a portion of the light beam (103) passes through the chromatic diffusing layer (5) before and after being reflected by the plurality of non-coplanar reflective surface sections (3′). Chromatic diffusing layer (5) is further configured to provide for—together with non-coplanar reflective surface sections (3′)—a specular reflectance that is larger in the red than in the blue and for a diffuse reflectance that is larger in the blue than in the red.

A hull form design which incorporates bi-lateral semi-sponsons disposed on either side of a non-stepped V-shaped center hull section. The semi-sponsons extend the entire length of the hull form and comprise protrusions extending away from the center section. The semi-sponsons are delimited by longitudinal steps extending below the hull bottom an equal distance from the centerline on opposite sides of the hull. This design is a hybrid of conventional “V” hulls and catamarans and improves the roll and turn initiation time of convention monohull designs.

The present invention provides a fluorescent lamp which can suppress the reduction of the fluorescent film from the glass on the luminous tube and the total beam, and can obtain a good beam increasing characteristic. A light-transmitting luminous tube (40) and a fluorescent film (13) arranged inside the luminous tube (40). The fluorescent film (13) contains spherical metal oxide (15) particles.
