#2752: MouseRehouse

Many people don’t like mice in their homes, but don’t want to kill them.

They therefore use humane traps and then have to move a live mouse to some distant location.

Today’s invention is a discreet way to trap a mouse and then covertly release it somewhere else during a walk away from home.

It consists of a humane trap which can be attached to the end of a walking stick.

You attach the trap, with mouse in, to the stick, go for a walk and then press a catch in the handle to allow the mouse a new lease on life.

#2751: BellShells

Today’s invention is a set of physically large kettlebell-shaped shells made of stretchy foam rubber.

These are designed to have a slit in the top so that even a large kettlebell can be placed inside. The shells have no external markings.

The shells are all the same size and may accommodate conventional kettle bells of any weight, so that people aren’t
a) tempted to show off with weights that are too heavy or
b) embarrassed by using very small weights when beginning exercise.

#2750: Officerifle

I’m given to understand that officers in modern warfare often have to carry a rifle they’ll never use, in order not to be seen as a priority target by eg enemy snipers.

Today’s invention is therefore an imitation rifle which is super lightweight and which can be carried, on a strap, by officers just to help them avoid being singled out.

This could be hollow, in order to hold securely any lightweight, loose items that an officer needed to carry.

It would be marked so that anyone close by could see it was fake and not attempt to use it for self defence.

#2749: ScreenSucker

Somebody invented a new way to harrass thoughtless motorists…a suction device that attaches to the windscreen of a badly parked car in order to make it undriveable.

So, in order to further the fight against officialdom, I just invented the obvious countermeasure.

It’s a (small) suction clamp that I leave attached to my screen, which prevents their barnacle clamp from ever being attached. A sign would say ‘Do not attempt to remove’. The lever arm would be lockable, when the sucker was in place.

(I might couple that to a dash camera so that any attempts to remove my sucker would be recorded for use in court, if my vehicle got damaged).

#2748: WaitingWeighting

People who contact call centres sometimes get angry and verbally abuse the staff who pick up the phone.

Today’s invention offers a way to limit that behaviour.

Once a caller starts using a raised voice or bad language, the call taker can flip a switch to disconnect them and issue an automated message to say,
“You have been abusive and you have been reinserted in the queue 10 positions backwards.”

The call taker might be able to select the number of positions to accord with the intensity of the caller’s rudeness.

A system like this could also ensure that the caller was not dealt with by anyone who had retarded their call.

#2743: Hidelivery

Today’s invention is a box which looks like an outside air conditioner (complete with the appearance of a fan and plumbing).

This is actually empty and with a keypad-secure lid.

Anything sizeable ordered from eg Amazon will be labelled with instructions to leave it inside the air conditioner, together with the code for the lock.

If nobody is at home, thieves who steal things from porches will be thwarted.

#2740: DriftDye

Drifting cars is now a common form of entertainment.

Today’s invention is a drift car tyre which is made with different coloured dyes embedded within its layers.

As the performance continues, the crowd gets to see changes in the colour of smoke produced. It might be possible to achieve a similar effect by attaching a disc to each wheel so that, as it spins, the outer edge rubs on the road and generates eg pyrotechnic effects or just frictional sparks.

There could even be a colour of tyre dye chosen to indicate that a lower safety limit had been reached.

#2737: Rollinks

Today’s invention is a tanktrack link which has a roller embedded in it.

This roller (red) contains a lock which can be activated wirelessly, so that as the track is lifted off the ground, the roller falls into a different position vertically (and is again locked). Normally the rollers would all be locked in the up, or fully withdrawn, position (right).

This allows rollers in the ground contact position (left) to act as rollerskate wheels, so that shallow declines can be moved down under gravity, with fixed tracks. They also allow differential motion of one track relative to another, lessening damage to both the tracks and the ground.

Rollers can also be braked, so that, in the fully down position, extra traction is provided.

#2734: Mudeflectors

Running along country tracks and trails in Winter means that your legs get coated in mud -especially at the back. This can be pretty hard to clean off.

Today’s invention is therefore a set of stretchy mudflaps for one’s running shoes.

These fit as shown and keep the mud spray to a minimum. They would be easy to wash clean with a hose.

#2731: LogisticLogin

Strong passwords are often hard to remember. That seems to be because the very patterns which allow us to form memories are also the things which hackers can get to grips with most easily.

If you use any simple algorithm to generate a password, for example, then that is a source of insecurity.

Using a slightly more complicated algorithm, which generates a unique password to each site, seems like a better idea.

URLs are, by definition, unique to websites, so today’s invention relies on that.

Say I want to login to https://iotd.patrickandrews.com/wp-admin. One way would be to always use a password consisting of the 2nd, 3rd, 4th, 10th, characters ie otdc…Logging into http://www.bbc.co.uk/news/education would use password bccw, etc.

This removes any need to memorise anything other than a single string of digits. One’s browser could easily remember the algorithm and when it loses the information, as mine often does, it would be easy to reproduce manually, as required.

I’d take it one step further, because I have such a poor memory. Instead of 2,3,4,10 etc, I might choose a sequence to generate my string of digits, such as ‘primes minus 2’ ie 3-2=1st, 5-2=3rd, 7-2=5th, 11-2=9th, etc or even some variant on the logistic map over integers (which is already used to generate pseudorandom bit sequences).
