Amazon Patent Describes Wirelessly Powered Remote Displays

GeekWire has discovered a patent filed by Amazon CEO Jeff Bezos and Vice President Greg Hart that describes remote screens, or rather, devices that are mere screens relying on the cloud to produce content and power. These screens only need enough hardware to light the displays, receive the content and produce audio if needed.

According to the patent, Amazon's remote screens wirelessly connect to a base station that handles all the "behind the scenes" work like receiving content from the cloud and transferring it to the screens, processing gesture input and voice commands, storing data and more. The base station also wirelessly sends power across its network, keeping battery requirements at a minimum, if at all.

"Similar to Wi-Fi services today that require a fee to access, users could be charged an access or usage fee to utilize the system including usage of the wirelessly transmitted power," the patent states. "[A] rechargeable battery may however provide additional benefits."

As an example, several stations could be established throughout a college campus. The screens, distributed to students, would receive both data and power without the need for any cables. In turn, students wouldn't need to carry around volumes of text books for each class, but instead load books up on the electronic screen similar to the way we open ebooks on tablets.

In one diagram, the screen is labeled as a portable display, which consists of the screen itself and the tablet-like chassis. Possible solutions include an electrophoretic display, a cholesteric display, a liquid crystal display (LCD), and a light emitting diode (LED) display, as well as a combination of one or more displays. The screen may also be touch-based, possibly eliminating the need for buttons.

The primary station will consist of a power source, a processor and an antenna. The power aspect may be comprised of an electrical power cord that plugs into an electrical outlet, a battery, or any other combination of power components. The processor may contain more than one core, and more than one graphics core.

"[The] antenna is not required for primary station to wirelessly transmit power or data to a portable display," the patent states. Later on it talks about displays that are mounted on car windshields and thin displays that could adhere to glasses.

    What the iPad started, Amazon take another bold step closer.
