the Inquirer writes that "Apple has lodged a patent for a device charger that works only with one device". In other words, you won't be able to charge your i[THING] with anything else than original charger. They mention that this would be good to make stolen devices unusable and thus preventing thefts.
As people don't have enough chargers already. Instead of thinking how to reduce the number of chargers by unifying them, Apple is thinking about increasing the number of chargers. If your family has two (or more) i[THINGS] you'll need two (or more) different chargers to charge them. This is stupid and I hope it never reaches the production phase. Not to mention the problem if the charger fails.
Apparently global warming and current heat wave is affecting Apple R&D people.
