Justice must be both done and seen to be done.

Apparently, however, when judges are hungry, they are much less likely to eg grant parole.

Today’s invention is therefore a way to lessen the large fluctuations which have been measured in judicial opinion.

Before passing judgement, lawyers could require a judge to self-administer an electronic test.

This would take the form of a games console which would run some perception/reaction tests and take a drop of blood to monitor blood glucose level (it might also be used to detect other substances).

If this, or the concentration test scores, had fallen below average for the individual, lawyers could ask that a court case be deferred until the judge had had lunch and a rest.

There have been lots of articles online of late about how Formula 1 drivers have special seats, designed, as everything in their lives, to satisfy their personal requirements.

Today’s invention is instead to equip open-cockpit race drivers each with an inflatable suit, which would completely take the place of a seat.

The suit would contain bladders filled with air, providing exactly the right level of support in all the right places.

This would reduce the weight in the car, provide extra lateral bracing during cornering as well as neck protection during braking.

The suit bladders would be deflated to enter the car and on sitting in the bare frame, they would be connected to a source of compressed carbon dioxide.

In the event of a crash, the air bags would help provide protection and certain bladders on the sides of the suit would automatically deflate -helping the occupant/wearer to get out rapidly (It might even be possible then to use impact energy to overinflate bags under the driver’s body, to help lift him out of the cockpit).

The gas would also act as an additional fire retardent.

Robot quadricopters can now be act cooperatively and fly in an aerobatic swarm (See eg this and this).

These developments open up the real possibility of today’s invention: a mobile, bullet-resistant shield for infantrymen.

Each member of a platoon would be assigned say five of these machines.

As he or she exited a helicopter or armored personnel carrier, their copters would take off from their locations on its surface and fly in front of the troops.

Each machine would carry a small shield, made of bullet resistant perspex. This would avoid obscuring the way ahead.

In the event of an attack, the copters would instantly react and cooperate so as to form the best possible defensive shield in front of the lead soldiers.

If any units were damaged, the others would compensate, giving time for a defensive response.

Audi once developed a safety system which moved the engine in a car during a crash so as to avoid impact with the occupants.

Today’s invention moves the engine and gearbox in a vehicle, but for different reasons.

As shown, the (blue) engine/gearbox unit is threaded onto a splined drive shaft and is free to slide along this axially within an enlarged transmission tunnel between the seats.

Its position would be changed using a worm/wheel combination and so the vehicle could automatically adjust its centre of mass from moment to moment according to the current dynamics (as measured by several accelerometers).

Cars would therefore be capable of sharper direction change, under better control than ever before.

When a professional photographer takes a picture, from a position physically close to his subject, the chances are that his SLR mirror mechanism will make an intrusive noise.

This, I’m told by people who do this for a living, is actually valuable feedback, which they would not want to do without -even though it can be an irritation for someone who is concentrating on a task.

Today’s invention is therefore a digital SLR with a carefully silenced mirror (this could be done with a combination of softer gears and a padded seal onto which the mirror would be brought quietly to rest).

In order to provide the required ‘feel,’ an electronically simulated mirror mechanism noise could be supplied to the user via an earpiece.

This would be chosen from a range of such noises -as recorded from a number of historically significant cameras or generated from a combination of these.

Washing fruit and veg is usually enough to reduce surface contamination by bugs and pesticides so that one doesn’t get ill when eating them.

It is, however, a bit hit-and-miss.

For people who have impaired immune systems or extreme sensitivity, today’s invention may help.

It is a sand-blasting booth which allows a variable quantity of fruit or veg to be placed into a rotating drum. Except of course it would use ice crystals, rather than sand, as an abrasive spray.

These would be formed continuously on a refrigerated plate set in a constant-speed air stream so that crystals of a given size were blown off the surface at a known rate.

Each type of food item would have a different recommended spray duration (tomatoes would need only a fraction of the time that carrots require).

This might even allow for more creative food preparation…and less waste -if you wanted to peel only the outermost layer of your potatoes, for example.
