Abstract: An internally-illuminated medical data card in a credit card format containing a summary of the medical history of the bearer germane to his existing medical condition. The card, which is of laminated construction, includes a plastic core panel having light-transmitting properties, one face of the panel having formed thereon a metallized layer functioning as a double-faced mirror. Mounted on the layer and on the other face of the panel, respectively, are front and rear film transparencies containing medical data in a directly legible scale, the combined data affording the required summary. The long edges and one end of the panel are in a concave formation to define reflective convex terminations whereby light entering the remaining flat end is transmitted through the panel and is reflected by the convex terminations and by the inner face of the mirror to provide multiple internal reflection, causing the light to illuminate the front transparency to enhance its readability.

Abstract: An easily-opened case for housing diskettes having data magnetically recorded thereon. The case not only acts to protect the diskettes from contamination and physical injury but also shields it from stray magnetic fields, electrostatic discharges and from ionizing radiation which, if the diskettes were exposed thereto, would act to erase or distort the data recorded thereon. The case is formed of a box adapted to house the diskettes and a cover to the rear of the box. The box and its cover are fabricated of aluminum or other material having shielding properties with respect to stray fields, electrostatic discharges and ionizing radiation. The cover is provided with front and side flanges which when the cover is closed lie against the front and side walls of the box, and with an outwardly inclined rear baffle which when the cover is closed assumes about a 45 degree angle with respect to the rear wall of the box, whereby when the cover is raised, the rear baffle then lies against the rear wall of the box.

Abstract: An internally-illuminated medical data card in a credit card format containing a summary of the medical history of the bearer germane to his existing medical condition. The card, which is of laminated construction, includes a core panel formed by front and rear plastic sections having light-transmitting properties, a metallized layer functioning as a double-faced mirror being sandwiched therebetween. Nested in the respective faces of the core sections are front and rear film transparencies containing medical data in a directly legible scale, the combined data affording the required summary. The long edges and one end of each core section are in a concave formation to define reflective convex terminations whereby light entering the remaining flat end is transmitted through the section is reflected by the convex terminations and by the mirror to provide multiple internal reflection, causing the light to illuminate the transparencies to enhance their readability.
