Abstract: A reflectometry instrument includes a light source for emitting an illumination beam that illuminates the macula. A portion of the illumination beam is reflected from the macula and forms a detection beam. The detection beam is indicative of macular pigment in the macula. The instrument also includes a first mirror for reflecting the illumination beam toward the macula and for reflecting the detection beam from the macula. The instrument is configured so that the illumination beam and the detection beam remain separated between the macula and the first mirror.

Abstract: Lightweight advertising emblems that are readily knocked down into compact packages are mounted upon light standards or upon free-standing masts which use bases that incorporate local ballasting agents such as paving stones, gravel, sand, stones or water. The emblems have a display surface which may be planar, or may be wrapped to form a three-dimensional object, such as a giant sized paper drinking cup, complete with straw, an olympic style torch or other representation. The display surface is preferably of knitted material such as a polyester fabric, that may be printed upon by a silk-screen process, and is highly resistant to creasing. In the case of planar, banner-like displays, the mounting may include a rotary bearing, to permit weathervaning of the banner, for minimum wind resistance and dynamic display.

Abstract: An outdoor advertising system has a lightweight hollow mast; a mounting base for the mast; a direct-insert anchor securing system; and a range of three dimensional artifacts, and banners that are weather insensitive. The mast mounts on the base, having lightweight fittings, including a top-mounted rotatable cantilever arm enabling the arm and its banner to “weathervane” in the wind. An ovoid hooped frame embodiment pivotally cantilevered from the mast, supports a sleeved banner like a wind-sock. The ovoid shape provides effective side display areas. Another elongated banner embodiment with several triangular banners in spaced angular relation as a form of tree encloses the mast, with the bottom outer corners of the banners ground anchored, serving as mast stays. A drinking cup embodiment may be mounted about the mast. The fabric artifacts stand up to fourteen feet in height.
