#1122: RouletteJet

The pilots of fighter aircraft can survive accelerations of over 9g (wearing the right suit and performing the recommended muscle bracing techniques). When being pursued by a missile, their ability to escape is limited by their own physiology, rather than the manoeuvrability of their planes.

People are notoriously bad at behaving randomly, so any missile worth its salt can probably predict a pilot’s changes of direction well enough, once it gets close, to be able to score a hit.

Gary_Romin_jet

Today’s invention is therefore a system which detects when a missile has locked on, gains height rapidly and then automatically undertakes a rapid, random sequence of spins, jinks and darts, always keeping each acceleration of the plane below the damage level for the individual pilot in question.

(The human body is much more tolerant of g-force when it is applied across the body than along its length and pilots are already tested in centrifuges to determine their passing-out thresholds).

Each plane would thus know the limits of its crew -making for a very rough ride, but no rougher than ejection and certainly preferable to the alternatives.

#1121: Hatchbackwards

Hatchbacks are a great idea (especially in this form).

When it comes to reversing them, however, life becomes complicated.

Helmut_Gevert_aston

Today’s invention is therefore a small modification to all such vehicles. When reverse gear is engaged, the hatch is unlocked and automatically raised so as to be only slightly higher than the roof of the car.

This allows the driver to see behind him or her very much more clearly (and also acts as an extra signal that a reverse manoeuvre is in progress).

#1120: Shimyopia

Today’s invention is an alternative to conventional contact lenses, at least for those who are shortsighted. People with this condition (I’m one) have eyes which focus the incoming light in front of the retina, rather than at its surface.

So, why not distort the back of the eyeball inwards just a little? Isaac Newton tried this using a bodkin (packing needle), but I envisage something more like a fat contact lens, made of eg PTFE which would be attached to the outside of the rear sclera, causing the retina to be moved forwards a little but without distorting its shape and staying out of the way of the optic nerve as the eye rotates.

This could be put in place under local anesthetic (and a more advanced version might contain a radio-controlled piezo-electric spring, allowing the amount of distortion to be varied externally).

#1119: SnoWheels

Given the horrors of trying to fit snow chains, today’s invention is a low-tech alternative.

The user slightly deflates his tyres and slides over them the snow-studded covers which fit snugly.

snowheel

The tyres are reinflated, providing each with a firmly-attached, much grippier, outer cover.

#1118: JetTrack

I was inspired by this system, which allows someone to fly over water, to come up with today’s invention.

It’s a personal ‘jetpack’ the motors of which are supplied with electricity from a self-powered battery cart travelling on the ground. This could be remotely controlled to follow the pilot and avoid stressing the power cable.

The system allows flight only to a limited altitude but the time aloft could be as long as a whole day at a time. The cart might even be equipped with a large air bag in case the motors failed -so that the pilot could safely crash land.

#1117: Sightlight

Many firearms help the user ensure they are aiming accurately by shining a laser beam onto their target.

If this happens to be a suspected criminal, they may look down, see the spot and realise their predicament…but they may not.

sightlight

Today’s invention is an attachment for such a laser equipped weapon which modulates the outgoing laser beam into digital bursts. It can detect any reflected light and determine the distance from the target.

This allows a lens system to deflect part of the beam upwards to where the face of the target person should be…alerting them to the fact that they are in danger.

#1116: FlowSnow

I’m fascinated by the mechanics of ice crystal formation.

The final, unique shape of one such crystal is a representation of its personal history as it falls through temperature and humidity gradients.

dlee_crystal

Today’s invention is a system which injects pure, hexagonal seed crystals into an engineering airflow stream at different points and then, by automated image analysis, determines statistically what gradients they have each encountered.

This provides a new form of flow monitoring for low-temperature systems.

#1115: Buttbough

I stayed at a hotel in Birmingham recently where I witnessed a biggish fire in an outside ashtray. The staff seemed not to care less, which was their default viewpoint on everything.

Today’s invention is a safer ashtray for those determined to continue lolling about entrances whilst smoking.

ashbin

It’s in the form of a hollowed-out tree branch with a wooden lid. The branch end and lid are angled to allow the container to be pressed into eg a flowerbed and also so that rainwater will flow in through the hole in the top. This hole is small enough to stop people putting waste paper etc in but just big enough to admit a cigarette.

Before use, some funghi spores are dropped in so that the whole system will be converted to compost -suitable for digging directly into the flowerbed, once full. The rainwater helps the funghi grow and greatly reduces the chances of a fire starting within the branch.

#1114: HighLights

Today’s invention is for athletes of all standards working on a climbing wall.

Shoes and gloves would each be fitted with a small coloured lamp.

Alan_Eno_climbing

Hand and footholds would each have an array of four different coloured LEDs (recessed, but visible).

A trainer could remotely activate a pair of lamps on foot and foothold to indicate were best to step next (or even challenge the wearer to do non-standard moves). This process could also be automated and the speed of ascent adjusted to the experience level of the climber in question.

#1113: ScissorStrut

When using a tripod to take photographs, its positioning tends to dominate the composition.

Today’s invention helps with this by allowing an interior photographer to place his camera wherever required and then extend two scissorlike mechanisms upwards and downwards before locking them in place.

stretch

The pads on either end help to form a rigid bridge between floor and ceiling, allowing images to be captured from the desired location and then quickly repositioned.
