The 13 craziest Google patents

Google filed a patent in 2014 for a device that could correct vision without needing to use contacts or glasses everyday. The person would have to undergo a surgical procedure that would allow a doctor to insert an "intra-ocular device" to the lens capsule for it to work though.

The solar-powered contact lenses would collect health data like glucose levels and internal body temperature. The lenses could even come with special capabilities like the ability to read information in bar codes. The patent was filed in 2012.

Like the solar-powered contact lenses, the smartwatch could provide diabetics with a better way to monitor their glucose levels. When going to draw blood, the watch would send a surge of gas into a chamber that has a microparticle that would then puncture the skin, draw blood, and suck it into a barrel for testing.

The patent was filed in 2014.

Many know about Google's Project Wing, a delivery service where a drone would lower packages to the ground. A patent filed in 2014 added another element to that service, outlining how the drone would lower packages to a robot on wheels that would shuttle it to safe holding locations.

The patent outlines as a system where glasses could project a keyboard onto the wearer's hand. A camera attached to the glasses would detect the keys pressed by the user. But it's worth noting Google has backed mysterious, augmented reality firm Magic Leap, so any patents relating to AR could be fairly obsolete if all goes well on that front.

The patent describes a tattoo would embed a microphone and lie detector into your neck! The tattoo could pair with your phone wirelessly, allowing you to talk without putting the phone to your mouth. A more creepy use case outlined in the patent is having it detect skin resistance in users to tell if they're lying.

The patent filed in 2012 outlines a portable fan that would attach to your body and spray fragrance when it detects you're exerting yourself to cover up body odor.

Better yet, it will make sure no one you know is aware of your body odor by connecting to your contacts to see where your friends are. It will then provide routes to take if you're fairly smelly on the streets, say after the gym, that will avoid any run-ins with people you know.

The patent outlines software would let you insert plain text or upload conversations and have them get transformed into comic strips, with the purpose of these strips getting shared on social networking websites like Facebook.

The patent outlines a walking stick equipped with imaging sensors and one or more cameras that would take pictures as you walk to create a visual simulation of the area.

The patent outlines a crib embedded with sensors so it can monitor your baby's movements and keep tabs on environmental factors to make sure the baby is safe. For example, you could program the sensor to send an alert to your phone if the room gets too hot or too cold.

The crib could also detect what's going on with your baby and attempt to respond to the issue. So, if your baby starts crying, the crib could activate an attached entertainment device to display LED cartoon animals on the ceiling to calm the baby down.

Google wants to make collisions safer with self-driving cars.

This patent filed in 2014 outlines putting an adhesive layer on the hood of a driverless car that would be covered by something that isn't sticky. In the event you hit someone, the outer layer would be removed to expose the glue, sticking the person to the front of the car.

A patent filed January 2015 outlines embedding sensors into different parts of the bathroom, like the toilet seat and bath mat, to measure how healthy your heart is. For example, the sensors in the bath mat could record your heart beat by measuring your body's electrical behavior.
