Abstract: A connectible component is connected to a housing. A sensor of the housing is utilized to detect an identity element of the at connectible component. The connectible component is identified utilizing the at least one sensor. In some implementations, identification of the connectible component may identify whether or not a connectible component is connected to the housing. In other implementations, identification of the connectible component may identify the type of connectible component that is connected. In such implementations, the housing may house an electronic device and the electronic device may be configured based on the type of connectible component that is connected.

Abstract: An input mechanism, such as a crown, detects amounts of applied force. In various examples, an assembly including an input mechanism has an enclosure; a stem coupled to the enclosure such that the stem is rotatable, translatable, and transversely moveable with respect to the enclosure; a sensor, coupled between the stem and the housing, to which force is transferred when the stem moves with respect to the housing; and a processing unit coupled to the sensor. The processing unit is operable to determine a measurement of the force, based on a signal from the sensor.

Abstract: A wearable electronic device includes a body, a housing component, a band operable to attach the body to a body part of a user, and a force sensor coupled to the housing component. The force sensor is operable to produce a force signal based on a force exerted between the body part of the user and the housing component. A processing unit of the wearable electronic device receives the force signal from the force sensor and determines the force exerted on the housing component based thereon. The processing unit may use that force to determine a tightness of the band, determine health information for the user, adjust determined force exerted on a cover glass, and/or to perform various other actions.

A rear face antenna may be formed using a wireless power receiving coil as a radio-frequency antenna resonating element or may be formed from metal antenna traces on a plastic support for light-based components.

Abstract: This application relates generally to various embodiments of a magnetic wristband. More specifically the application describes a design for a magnetic wristband having a number of configurations. In one configuration the wristband is magnetically coupled around a user's wrist. In another configuration the magnetic wristband can be magnetically coupled around an electronic device to which it is attached. In this second described configuration the magnetic wristband acts as a protective cover for the electronic device to which the wristband is attached. In this way a user can reduce the likelihood of damage being inflicted upon the electronic device while it is not being worn.
