ICYMI: Hyper directional sound guides runners

Visually impaired athletes can use the system on indoor tracks.

Today on In Case You Missed It: Malaysian sportswear company Ash Be Nimble has expanded their product line to include the Handbag Dyetonator, a fob-style accessory that will expel ink and smoke onto anyone who walks (or runs, or scoots) away with your bag. The Dyetonator attaches to a purse similar to a keychain and can be deployed via SMS message (so hopefully your phone wasn't in that bag...) to mark a thief for easy identification. It also contains a GPS tracker, should the culprit succeed in getting away with your pocketbook. It's still in early testing phases, and certainly isn't foolproof, but the idea of a dye pack exploding on a thief is a satisfying thought, so hopefully this will eventually make it to market.

Meanwhile, a Swedish sound design company has come up with an inventive way to assist sight-impaired runners: Sound, or rather, "hyper directional sound.". The company, Lexter, spent two years creating what is essentially an auditory flashlight which projects a narrow-band beam of sound to guide runners along a path. Should runners stray from their lane, the tones can guide them back into place. The system uses a pair of speakers to emit the tones, and given that some special olympic athletes have expressed interest, might be available on indoor tracks sooner rather than later.
