Abstract: Input devices can employ ultrasonic touch sensing capabilities that allow user inputs to be detected through conductive materials, such as metal enclosures. The ultrasonic touch sensing can include generation of ultrasound signals with a piezoelectric layer. The ultrasound signals can be reflected when a user or other object is in contact with a housing, and the reflected signal can be detected by the same piezoelectric layer that produced the ultrasound signal. Such a piezoelectric layer can include a piezoelectric polymer, such as polyvinylidene fluoride (PVDF). An array of electrodes distributed on opposing sides of the use of electric layer can be operated to generate ultrasound signals and detect reflected signals. Such an input device can be operated in conjunction with a conductive (e.g., metallic) housing, conform to a variety of shapes, and be compact and lightweight

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.
