Abstract: An electronic device comprising a connector including a plurality of contacts and a liquid detection module coupled to at least one contact in the plurality of contacts. The liquid detection module can be configured to generate and apply a time varying voltage or current to the at least one contact over a range of frequencies, measure complex impedance including phase and magnitude at the at least one contact, and determine whether liquid intrusion has occurred on the contacts based on previously measured signatures of phase and magnitude versus frequency.

Abstract: A wirelessly locatable tag may include a first housing member defining a first exterior surface of the tag, a second housing member removably coupled to the first housing member and defining a second exterior surface of the tag, and an antenna assembly. The antenna assembly may include an antenna frame defining a top surface and a peripheral side surface, a first antenna on the antenna frame along the peripheral side surface and configured to communicate with the electronic device using a first wireless protocol, a second antenna on the antenna frame along the peripheral side surface and configured to send a localization signal to the electronic device using a second wireless protocol different than the first protocol, and a third antenna on the antenna frame along the top surface and configured to communicate with the electronic device via a third wireless protocol different than the first and second protocols.

Abstract: A wirelessly locatable tag may include a first housing member defining a first exterior surface of the wirelessly locatable tag and an interior surface opposite the first exterior surface. The wirelessly locatable tag may further include a second housing member defining a second exterior surface of the wirelessly locatable tag a first antenna configured transmit the wireless signal using a first wireless protocol, a second antenna configured to communicate using a second wireless protocol different than the first wireless protocol, and an audio system. The audio system may include a magnet assembly configured to produce a magnetic field and a coil positioned within the magnetic field and coupled to the interior surface of the first housing member, the coil configured to interact with the magnetic field to impart a force on the first housing member, thereby moving a portion of the first housing member to produce an audible output.

Abstract: A wireless power system may use a wireless power transmitting device to transmit wireless power to a wireless power receiving device. The wireless power transmitting device may transmit wireless power at a wireless power transmission frequency. Wireless power signals at the wireless power transmission frequency can create interference with a sensitive electrical component in the wireless power receiving device when the wireless power transmission frequency lies in a sensitive frequency band associated with the component. Measurement circuitry in the wireless power receiving device can measure the wireless power transmission frequency. In response to determining that the wireless power transmission frequency lies in a sensitive frequency band, the wireless power receiving device may send an in-band wireless power level adjustment request to the wireless power transmitting device. The request causes a frequency adjustment that moves the wireless power transmission frequency out of the sensitive band.
