A laser attached to the base of the vacuum throws out a green spread of light that illuminates hair, dust, and dirt particles as they come into contact with the cleaning head. It makes vacuuming a lot more fun and can even help you know whether you’re picking up large or finer dust.
Dyson’s latest cordless vacuum adds a green laser to its cleaning head, making the vaccum a bit more fun to use. It uses a new acoustic piezo sensor and microprocessor to monitor air intake to gauge the size and quantity of dust being vacuumed up, and increases power and suction when it senses that there’s a lot of heavy dirt in the way.
To create an optical trap, physicists must place highly focused laser beams to generate dips or “pockets” in potential energy, where individual particles can be held in place. To ensure this, the pockets must overlap with micrometre precision, says Gautam Ramola of Bonn’s Institute of Applied Physics.
Dyson has a new vacuum with a laser light that illuminates dust particles you wouldn’t normally be able to see, and it claims this will help you clean even harder. It’s also got a new sensor that detects the size and amount of dust being vacuumed, which will increase suction power.
When a laser beam strikes an atom, it can change the atom’s state in a very significant way. Such changes can be used in atomic-scale quantum computing, which solves problems that conventional computers cannot.
In order to do so, physicists need to know where each individual atom is in space. To do this, they need to align a laser beam to the precision required.
Physicists around the world are working on high-power lasers that could physically tear particles out of empty space. Such a powerful beam could demonstrate that matter and energy are interchangeable, as Albert Einstein theorized.
The laser beam itself is invisible when it hits dust or gas particles in the atmosphere, but a new technique from the University of Bonn makes it easy to visualize it under vacuum conditions. This should simplify the ultra-precise adjustment needed for quantum optics experiments.
This type of laser trap is a step towards atom-based quantum computing and other technologies. It uses highly focused (criss-crossed) laser beams to generate dips in potential energy – pockets that can hold and manipulate individual atoms. Scientists can then move these pockets back and forth, allowing an atom to be transported to a specific location in space.
Dyson’s latest cordless vaccum comes with a green laser light mounted on the hard floor cleaning head to illuminate dust and make it easier to see what’s been picked up. You can also use the vacuum to track how well the motor picks up dirt on a color LCD display.
The laser is angled at 15 degrees, so it illuminates small-to-medium particles that would otherwise be invisible to the naked eye. It’s particularly helpful inside homes where a lot of dirt is lying around, like bare floors or carpet.
A few vacuums on the market have lights in their heads to illuminate what you’re cleaning. The Dyson V12 Detect Slim does this in the form of a green laser, which shines down onto a hard floor, and highlights any dust particles that are visible to the naked eye. It’s the kind of thing that makes a chore feel like a game and makes vacuuming floors more satisfying. Its battery life is good, with 60 minutes of runtime (on eco mode on hard floors) when used without an attachment. It can also be used in self-adjusting ’auto’ and ’boost’ modes to adjust suction intensity based on the surface being cleaned. It has a removable battery too so you can keep a spare for when the original one dies out.
