Browsing around for bike-related goodies today, we came across this brilliant example of proletariat problem-solving in the name of an improved urban cycling experience. They call it the Traffic Loop Sensor Activator, or sometimes U.S. Patent #7,432,827 --we call it a nice alternative to ...

HOW TO - Fool a stoplight into thinking your bike is a car - The loop sensor activator
MAKE Magazine — HOW TO - Fool a stoplight into thinking your bike is a car - The Loop Sensor Activator via Core77. A common problem for bicyclists, and in particular for bicycle commuters, is the traffic loop sensor. These are the devices which detect the presence of vehicles to control the sequencing of traffic lights at many intersections. Often, they are installed in figure-eight slits cut into the pavement near a traffic light. The way they work is to detect the slight change in inductance of the loop of wire buried in the slit caused by a large ...

Traffic Loop Sensor Activators for Bicyclists
Boing Boing Gadgets — ... don't work with modern loop sensor circuitry. One patented solution (see USP 5,652,577) has the bicyclist laying down a big piece of metallic foil or screen right on the road surface!. Christ, what you American bicyclists have to put up with. Here in Zembla, every street has bike paths, bicyclists are respected and feared in equal measure and there are even traffic lights for bikes only. Do I amaze you?

Intersection sensor activator puts an end to cyclist discrimination
Engadget — ... many traffic lights are governed by sensors in the pavement that give a green light only after they've detected the change in inductance when a large metal car pulls up. Before you take up arms, though, take a look at this recently-patented device that sends out a signal that fools the sensors so cyclists don't have to wait for a car to unwittingly play good Samaritan -- we suppose we'll try this out just in case before we incite a violent revolution.
