When I’m trying to recall a name or fill in a crossword clue, I often find myself knowing the correct stress pattern without being able to remember the exact word(s).

For example, I spent a week last year trying to recall the name of the actor who played ‘The Joker’ most recently. His name was ‘blah blah-blah’, with his first name beginning with H…maybe.

Today’s invention is a dictionary plug-in which helps with this kind of tip of the tongue memory recall.

Since online dictionaries usually contain both phoneme and stress pattern information (eg ‘Definition’ ?def-?-?nish-?n ), a user would be able to narrow his search for a word or phrase by specifying the pattern of stresses in such a nebulous memory trace eg blah-blah, blah-blah-blah.

This would be particularly useful to poets who often search for a particular sound pattern with an appropriate meaning, I’m told. It would also have helped when I was trying recently to remember the names of the early North American explorers, blah-blah and Clark.

I find it interesting that we seem to store such a rhythmic representation, but that the link to the specific sounds is harder to make.

Today’s invention is a double-ended lipstick.

Each end would have a different shade, so that wearers could experiment with various combinations of colour on the top and bottom lips.

Not only would this be visually striking, but for a more subtle effect, you could wear a lighter version of the lower-lip colour on the upper lip (to compensate for the natural shading there).

Public spaces contain fewer rubbish bins than ever before (partly because of the perceived need to deny terrorists receptacles in which to hide bombs).

This has led to a phenomenon called Litterplugs, in which people without access to bins find a convenient crevice and shove their litter there.

Today’s invention exploits this tendency by providing locations into which people can cram their refuse legitimately. They would shove eg crisp packets, crushed drinks cans, etc into the top of a gap between two plexiglass screens mounted on a wall.

This would allow inspection of the contents and when full, could be easily cleaned out by allowing one sheet to rotate about one corner fixing (red), dumping the contents into a larger, mobile waste bin.

It’s cool that Google have mapped the night sky.

This set me thinking that it might be really nice to create a cellphone app which allows the user to point his mobile device at the ground and see a simulation of whatever part of the world is beneath him (In the same way that fighter pilots can see through the floor of their planes, when wearing the latest helmets).

Scanning this backwards and forwards would show a number of spatially-arrayed labels, located on the outer, transparent surface of a simulated sphere (The onboard cellphone gyro could be used to calculate the required angles).

The labels could be set to show famous landmarks or the hometowns of emigrant relatives etc.

I’m told that ‘bingewatching’ of eg an entire TV series over a single weekend is a growing social phenomenon.

For those of us who are slightly less media obsessive, viewing an episode every now and then, via the now ancient DVD technology, can be deeply frustrating.

Consider, for example, the infamous boxed set. Although most players will have a ‘last time played’ memory function, this isn’t much help if you can’t remember which disc you are on.

Today’s invention is a simple labelling for discs which allows anyone to record where they stopped last time.

Discs would have episode numbers printed on them in the form of a clock face. When you put the disc away, simply leave it rotated to the ‘last episode watched’ marker, inscribed on the case.

If you live in a household with several independent viewers, one way to avoid who-watched-what-last? warfare would be to have cases come with a number of thin, disc-shaped sheets. These could be made in different diameters, centred on the hub, so that several people could record their separate histories (which might require a notch in the disc itself to ensure that it was always replaced at the same rotational position, relative to the box).

(Who am I kidding? I really want a boxed set which loads directly into a reader, box and all, and which gives no acccess to any of the disks, so that they can’t be lost, scratched etc.)
