Apple introduced the new MacBook, a laptop notable for its thinness, its gold coloring, and most surprisingly, the absence of all but one solitary port. It’s called USB Type-C, and it’s going to transform gadgets as we know them.

Envisioning a future of laptops with just one input—aside from the headphone jack. But, How do I charge it? Where does my SD card go? Why can’t I hook my computer up to more than two things at once?

The answer in USB Type-C (or USB-C for short).

A USB-C plug is about the same size as a micro-USB (8.4mm by 2.6mm), but it’s reversible. Like Apple’s Lightning connector, upside down and right-side up are one and the same.

It’s like a USB on steroids. First off, charging: USB-C can deliver bi-directional power. It can be used to charge a host device, or it can allow the host device to charge a peripheral. It can handle large loads too, delivering up to 20V at 5A (100W). That’s more than enough to charge up a notebook, or multiple mobile devices simultaneously.

USB-C is also faster than our current USB-B standard. Data transfers can run at rates up to 10 Gbps, but it’s backwards compatible with older USB standards, as long as you have an adapter. Right now, our fastest USB Type B devices transfer data at half that speed.

It’s still only one port. If you  want to plug other things into your computer , you’ll need an adapter, and Apple has a number of options already available: USB-C to USB ($19), USB-C to HDMI, and USB to VGA (both $79). DisplayPort, gigabit Ethernet, SD card adapters, and other connector standards should arrive soon, both from Apple and from third parties.

It’s amazing how The World’s Largest Company has a products fit in one picture .

“Apple may turn to optoelectronic sensor technology to help users of the company’s so-called “iWatch” keep track of their heart rate and blood oxygen saturation, according to a Friday report from China,” Shane Cole reports for AppleInsider.
“Cupertino, Calif.-based Apple was also considering the addition of blood glucose monitoring, but that feature is believed to have been scrapped due to the ‘inaccuracy’ of using optoelectronics for non-invasive blood glucose testing,” Cole reports. “Electronics industry analyst Sun Chang Xu made the predictions for China’s Electrical Engineering Times.”

“Broadly speaking, medical sensors using optoelectronics measure changes in light reflected by the body. An array of light-emitting diodes are used to pass light into tissue, and sensors detect the amount and color of the light that bounces back. Using optoelectronics for monitoring blood oxygen levels is a process known as pulse oximetry,” Cole reports. “Adding to the report’s plausibility, Apple has brought on multiple biomedical experts with expertise in optoelectronic pulse oximetry in recent weeks. New hires Marcelo Malini Lamego and Michael O’Reilly are former executives at pulse oximetry company Masimo Corporation.”
