  • Publication number: 20210096597
    Abstract: A computing system includes an electronic device, a cover or case for the electronic device, and an input device that is slidably movable yet attached to the cover or case. By positioning the electronic device on top of the input device, rotation of the electronic device which changes its vertical viewing angle also translates the input device. These can provide improved overall possible viewing angle adjustability, increased system stability at high viewing angles, laptop-like opening and closing behavior, lighter weight, and implementation using low-cost components.

  • Patent number: 10955875
    Abstract: Electronic devices and accessory devices for electronic devices are described. In some instances, an accessory device includes a keyboard and a cover rotatable with respect to the keyboard. In some instances, an accessory device includes a back panel and a foldable cover rotatable with respect to the back panel. These accessory devices may include several magnetic elements designed to magnetically couple with, and retain, an electronic device without any additional mechanical or other interlocking devices. In this regard, the magnetic elements in the accessory devices provide an external magnetic field sufficiently strong enough to retain the electronic device, and can counter gravitational forces and/or the weight of the electronic device. However, some accessory devices include additional magnetic elements that provide an external magnetic field that repels magnetic elements in the electronic device. Also, the magnetic elements may also be used to hold different sections of the accessory device together.

  • Patent number: 10524372
    Abstract: An enclosure is formed by coupling an outer cover to a back enclosure piece. The enclosure defines an interior volume for receiving components of an electronic device. The back enclosure piece is formed from a metal frame component and a non-metal outer cover. A metal layer overlaps the metal frame component and the outer cover within the interior volume. The metal layer has a thickness that provides support and shatter resistance to the non-metal outer cover. The metal layer can form an inductor of a wireless power transfer circuit.

  • Patent number: 10024689
    Abstract: This application relates to devices that utilize magnets and associated magnetic sensors. A magnetic sensor can be positioned and oriented with respect to a magnetic element such that the magnetic sensor is capable of detecting a horizontal magnetic field component in contrast to the conventional paradigm of detecting a vertical magnetic field component. This can be accomplished by orienting a magnetically sensitive surface of the magnetic sensor about ninety degrees with respect to a magnetic vector of the magnetic element.
