From smart belt that tells you to lose weight to hi-tech milk bottle: 10 cool gadgets at CES 2015

LAS VEGAS - Fancy a belt that literally watches your waistline and tells you when to lose weight? Or a hi-tech milk bottle that feeds information about your baby to your smartphone?

These are just some of the new devices that will debut at the International Consumer Electronics Show (CES 2015), one of the world's biggest electronics fairs that officially opens on Tuesday (Jan 7, US time) in Las Vegas.

The focus of this year's show will be on all things "smart", or Internet-connected, taking the cue from the theme: Anything can be connected, from clothing, cars, home appliances, to your pets.

About 36,000 exhibitors and an estimated 160,000 people are expected to attend the four-day show.

Here's a sneak preview of 10 cool devices showcased at a preview on Sunday:
