IBM Patents Dividing The Number 60 By Your Car's Speed
from the divide-by-zero dept
theodp writes ""A billboard," IBM explains to the USPTO in its newly granted patent for Determining Billboard Refresh Rate Based on Traffic Flow, "is a large outdoor advertisement." Guess you have to pad your writing a bit when a cornerstone of your 'invention' is dividing the number 60 by the speed of a car (in mph). To be fair, Big Blue explains things this way in the patent: "A system for determining the refresh rate per minute of the dynamic billboard based on the traffic flow information, wherein the refresh rate is equal to 60 mph/V, wherein V is equal to an average velocity in miles per hour of vehicles passing the dynamic billboard. If the average velocity is 60 mph, the new refresh rate of the dynamic billboard is one refresh per minute (i.e., each advertisement is displayed for one minute), while if the average velocity is 10 mph, the new refresh rate of the dynamic billboard is six refreshes per minute (i.e., each advertisement is displayed for ten seconds)." Which begs a question: Will you see an infinite number of ads if traffic comes to a full stop?"
