    Abstract: There is disclosed an apparatus for illuminating a sensing region having an object therein, comprising a reflector that is elongated in a first plane, the reflector having a width dimension that is less than a width dimension of a sensing region to be illuminated, and further having a first curved profile in the first plane about a center of curvature. In a preferred embodiment the reflector is disposed between the center of curvature and the sensing region. In a second plane which is orthogonal to the first plane and includes the center of curvature, a reflecting surface of the reflector has a second curved profile. A plurality of substantially Lambertian light sources each face the reflector for directing light thereto generally in a direction of the center of curvature for reflection toward the sensing region. The second profile preferably comprises a portion of an ellipse and a light source is disposed substantially at a primary focus thereof. The second profile preferably has a gap for transmitting retroreflected light generated within the sensing region therethrough. An upper portion of the second profile comprises a portion of a first surface of revolution selected from the group of ellipse and parabola, and the lower portion of the second profile can comprise a portion of a second surface of revolution selected from the group of ellipse and parabola, a light source being disposed at a focus of each of the first surface of revolution and the second surface of revolution. The assembly is combined in a scanner for reading optical patterns.

    Abstract: A personal sound delivery apparatus which can be worn by a person has speakers held close to the ears and does not include any insert into the auditory canal or any ear muff that could muffle or suppress other ambient sounds. In a preferred embodiment of the invention, a wireless speaker is anchored by an arcuate hanger shaped and dimensioned to rest behind the ear. The speaker is positioned within a range from 0 to 20 centimeters (0 to 8 inches) from the auditory canal and may be surrounded by baffles that focus the incoming sound toward the entrance of the auditory canal. In other embodiments, a pair of speakers are embedded into the collar of a garment, a scapulary that rests upon the shoulders, a clamp that is bridging the nape of the neck, in pendants suspended from the neck, or hidden in a pair of earrings.
