el làser protege a los ciclistas

Avances para indicar la presencia de ciclistas
Laser ciclistas
Ingeniosa idea del diseñador Leonardo Manavella: un emisor láser que dibuja un
círculo de luz verde alrededor del ciclista para indicar su presencia. El Laser
(que es como se llama el invento) dispone de unos sensores de proximidad, de
modo que si la zona del ciclista es invadida, por un coche por ejemplo, la luz
pasa a ser de color rojo y el ciclista es alertado con una señal acústica.
Eco Factor: Safety laser beam powered by bike movement.
A rise in the number of cars has led to an increase in the number of road
accidents. While our cars are much safer now than they were a decade ago,
bicycling still remains a risky way to commute. This problem is suffered
principally in the big cities where thousands of cars, motorcycles, bikes and
other vehicles share the same infrastructure.
Industrial designer Leonardo Manavella has come up with an ingenious product
that could make bikes the safest and greenest way to commute. Known as the
“Laser,” the system increases the size of a common bicycle with an elliptical
beam of light and gives it a size similar to a car. The principal aim is that
the bicyclists start to respect the same rights and restrictions as a car owner
does and the car owners are tempted to respect the bicyclists.
The Laser consists of four adaptable objects that are connected to a common
bicycle with an auto adhesive tape. Each product comes with a plastic case, a
laser light, distance sensor, a spherical head to regulate the light, three
horns and a rechargeable battery. The battery is recharged with the movement of
the bicycle with a dynamo located in the wheels of the bike.
The laser light draws an ellipse on the floor increasing the size of the bike.
If the sensor is violated, the laser light automatically becomes red and all the
horns start to scream, in a way alerting the rider and the vehicle that entered
the laser generated ellipse. Once the vehicle gets out of the perimeter, the
light again turns green.

LightLane, Wired.
Un invento parecido es el LightLane, con el que un proyector láser "dibuja" el
carril bici al paso de los ciclistas, aumentando notablemente su visibilidad:
LightLane's Lasers Make an Instant Bike Lane, en Wired.
Fed up with seeing friends getting clipped by cars, the designers at Altitude
combined two things we love -- bikes and lasers -- to create an instant bike
lane and make nighttime cycling a whole lot safer.
Their bike-mounted gadget, called LightLane, beams two bright red lines and the
universal symbol for cyclist on the pavement, neatly delineating a bike lane to
remind motorists to yield a little space. It should make everyone feel a little
more comfort on the road.
"Clearly one of the biggest benefits of bicycle lanes is that there is an
established common boundary that both drivers and riders respect and must stay
within," designer Evan Gant told Wired.com. "However, this requires a great deal
of resources and planning to implement, so we decided to focus on the fact that
the bicycle lane establishes a safety buffer outside of the bicycle's
footprint."
It should cost around $50, and we think it's the best idea for a laser since
Andy Samberg put one on a cat.
The LightLane started life as an entry to a design competition aimed at
promoting bicycle commuting. "Having witnessed several friends be hit by cars
while in traffic, we felt the intimidation of sharing the road was one of the
bigger barriers to commuting by bicycle," Gant said. He designed the gadget with
Alex Tee.
They experimented with different ways of increasing the perceived size of
bicycles, but decided they wouldn't work. "We quickly realized all of these
would compromise the rider's safety by increasing the probability of accidental
clipping," said Gant.
Such an approach also didn't consider the appeal of small size and
maneuverability. After all, if bikes were big and bulky they'd be called
pedicabs. Once they decided tinkering with the physical boundaries were out of
the question, Gant and Tee considered virtual boundaries created by lasers. They
decided it was a much better approach.
"Although it doesn't establish a clear and predictable path for a rider to
follow, it does encourage a driver to provide the rider with a wider berth by
capturing their attention in a different way," Gant said.
LightLane is only effective at night, of course, something Gant said underscores
the need for proper bike lanes. "Permanent lanes are much more proactive and
LightLane is more of a reactive solution to the problem," he said.
Gant and Tee are trying to determine the best color and orientation for the
lasers. Once they tackle that question, they'll turn their attention to
financing and building a prototype that is resistant to rust, easy to clean and
difficult to steal.
If we're lucky, they'll figure out how to make it scorch the paint off any car
parked in a bike lane.
