Abstract: A process is provided for characterizing a tactile response of a first mechanical actuator (e.g., button) based on a back off distance. The first mechanical actuator may include a plunger, a dome-shaped flexible membrane, and an electrical contact, all aligned with each other so that a contact signal is generated when the flexible membrane touches the contact. The plunger can be moved a first distance towards the contact until the contact signal is generated at a contact point. Then the plunger can be backed off a second distance from the contact point. This second distance may be called the “back off distance”. The particular feel of the first mechanical actuator can then be correlated to a particular back off distance. This process can be repeated a number of times to classify a number of different “feels” for the first mechanical actuator based on a number of different back off distances.

Abstract: Transparent structures for portions of electronic device housings are disclosed. The transparent structures are formed from multiple layers of transparent (optically clear) materials. The multiple layers can include at least an outer glass layer and one or more other transparent layers that can be either glass or polymer layers. The multiple layers can be bonded together with one or more lamination layers. Accordingly, multi-layer transparent structures that are formed from multiple layers bonded together are able to be not only thin but also sufficiently strong and resistant to damage. The multi-layer transparent structures are well suited for use in consumer products, such as consumer electronic devices (e.g., portable electronic devices).

Abstract: A wearable accessory device is disclosed. The wearable accessory device includes a flexible display coupled to a bi-stable spring. Coupling the display to the bi-stable spring allows the accessory device to be easily worn in a number of convenient locations.

Abstract: A portable computing device is disclosed. The portable computing device can take many forms such as a laptop computer, a tablet computer, and so on. The portable computing device can include at least a single piece housing. The single piece housing can be machined from a single billet of material, such as a billet of aluminum. The single piece housing can include ledges with a surface receiving a trim bead and a cover. Corner brackets can be attached to the single piece housing to improve the damage resistance of the housing.
