A projection system that projects a text or subtitle box onto an image minimizes the contrast between the text box and the image. A transition region surrounding the text box minimizes visual disruption to the image onto which the text box is projected. The positions of optical elements of a text projector enable the text box to gradually fade out. The text projector has a lamp that defines an object plane and a light path modifier. The light path modifier is offset from the object plane, toward the lamp to blend the borders of the text box into the image projected by an image projector.

An image projection system improves the brightness and/or color balance of a projected image. The system includes an auxiliary light source from which compensating light co-propagates with polychromatic light emitted by a primary light source along a primary light path. The compensating light has an emission energy content that minimizes an emission energy imbalance introduced by the primary light source. In a first preferred embodiment, the auxiliary light source is affixed at a location near the entrance end of a light tunnel such that the compensating light coincides with the primary light path before first reflection occurs. In a second preferred embodiment, the auxiliary light source is coupled to a light reflector adjacent to the primary light source and thereby allows the compensating light to propagate through the image projection system with the same efficiency as that of the light generated by the primary light source.

Infrared radiation receivers () of this invention include non-imaging optical concentrators () having light exit surfaces (); a light sensor () having a light entrance surface that is separated from the light exit surface by a small air gap (); and a soft, pliable, light transmissive medium () inserted in the gap to reduce the light transmission loss across the gap. The soft, pliable medium is held in place by either a recess () in the concentrator or by a surrounding annular ring ().

An arm-mounted cutting tool for hands-free, rapidly cutting line, string, or slender rope. The cutting tool employs a sliding guide worn on, and fitted snugly and firmly to, the user's forearm. The sliding guide is used to guide line, string, or slender rope into a sharp blade member that is interiorly located in a blade support opening so that no human body extremities, such as a finger, can reach the blade and be accidentally cut. The blade member according to one preferred embodiment consists of two opposing linear cutting edges which intersect at a mutually produced apex. The two opposing cutting edges of this so-called “V”-shape blade, and the sharp apex they produce together, make a very effective blade for cutting line, string, or slender rope in a single pass.
