Engineering Lab in 1943. Twenty-five experimental units were manufactured by RCA, and in 1950, Haverford College was contracted to field test them by the Veterans Administration. That study led directly to the development of more advanced models including the space age Laser Cane.</span><span style='font-size:11.5pt;line-height:150%;font-family:"Helvetica","sans-serif";color:#606060'><o:p></o:p></span></p></div><div><p class=MsoNormal style='line-height:150%'><span style='font-size:11.5pt;line-height:150%;font-family:"Arial","sans-serif";color:#606060'>Cranberg's device sent out a beam of light, which, when reflected off an obstacle or object, was detected by the machine. A vibrating button in the handle would suggest the distance from the object by changing its frequency. This and many other travel aids are part of our AER Warren Bledsoe Orientation and Mobility Archives Collection.</span><span
