Abstract: Methods and systems for detecting and compensating for expansion of rechargeable batteries over time. An expansion detector may be coupled to or positioned proximate a rechargeable battery to monitor for expansion thereof. After expansion exceeding a selected threshold is detected, the expansion detector may report the expansion to an associated processing unit. The processing unit may undertake to arrest further rechargeable battery expansion by modifying or changing one or more characteristics of charging and/or discharging circuitry coupled to the rechargeable battery. For example, the processing unit may charge the rechargeable battery at a lower rate or with reduced voltage after detecting expansion.

Abstract: Sensor assemblies for electronic devices are described. According to some embodiments, the sensor assemblies include solid-state sensors, such as capacitive sensors, piezoelectric sensors or piezoresistive sensors. The sensor assemblies can include a number of features that provide a compact profile, making them well suited for integration into small spaces of electronic device enclosures. The sensor assemblies can also include features that isolate movement of various parts of the sensor assemblies, allowing for accurate detection of a sensing event. According to some embodiments, the sensor assemblies are coupled to haptic actuators, speaker, or both, which mimic the feel of a mechanical button and enhance a user's experience.

Abstract: This application relates to a portable electronic device that includes an integrated pressure sensor. The portable electronic device includes a housing that defines a cavity with a number of components disposed therein. The cavity is sealed to form a volume of air within the cavity that is vented to the external environment through a barometric vent fluidly coupled to a first opening in the housing. A sensor measures a characteristic of a second volume of air within an isolated chamber that is vented to the external environment through a second opening in the housing. The second volume of air is isolated from the first volume of air within the housing of the portable electronic device. In some embodiments, the portable electronic device is a mobile phone and the sensor is a pressure transducer.

Abstract: Electronic devices and accessory devices designed for communication with electronic devices are disclosed. An accessory device suitable for use with an electronic device can receive the electronic device. Subject to authentication, the electronic device can read information stored on the accessory device through respective wireless communication circuitry of the electronic device and the accessory device. For example, the accessory device can store information related to the material makeup of the accessory device, dimensional information of the accessory device, and other integrated features. This information can be read and received by the electronic device. As a result, the electronic device can adjust a control system (that regulates thermal energy generation) by increasing a set point temperature that allows one or more processors to operate in a manner consistent with additional thermal energy generation.
