Techniques for detecting mating and un-mating of a first connector with a second connector include providing a pulsed voltage signal at a contact of the second connector and measuring a rate of rise of voltage at the contact. If the measured voltage at the contact exceeds a threshold voltage during the time the pulsed voltage signal is applied, then it is concluded that the first connector is not present and not mated with the second connector. If the measured voltage is lower than or equal to the threshold voltage during the time of application of the voltage pulse, it is concluded that the first connector is present and mated with the second connector.

This application relates to methods and apparatus for waterproofing an electronic device having an audio output. More particularly a method for dynamically forming an acoustic volume of air for a speaker component is disclosed. The dynamically formed acoustic volume creates a sealed volume of air that prevents moisture from entering a portion of the device that includes moisture sensitive components. By dynamically forming the acoustic volume during a blow forming operation, the acoustic volume can utilize unused space within the electronic device in a highly efficient manner by occupying small areas of unused space that would otherwise go unused.

Electronic devices may be accidentally exposed to liquid during operation. To detect liquid intrusion events, an electronic device may be provided with one or more electronic liquid contact sensors. The liquid contact sensors may have electrodes. Control circuitry may make measurements across the electrodes such as resistance and capacitance measurements to detect the presence of liquid. Liquid contact sensor data may be maintained in a log within storage in the electronic device. The liquid contact sensor data can be used to display information for a user of the electronic device or can be loaded onto external equipment for analysis. Liquid contact sensor electrodes may be formed from metal traces on substrates such as printed circuits, from contacts in a connector, from contacts on an integrated circuit, or from other conductive electrode structures.

Power transfer systems including a direct current source and a plurality of outputs operable in several modes. A ground mode may couple an output to circuit ground and a current mode may couple the output to the direct current source. The power transfer system may also include a controller configured to iteratively select a pair of outputs from the plurality of outputs. Once a pair is selected, the controller may set a first output of the pair of outputs to the current mode and the second to ground mode for a determined duration. After the duration has passed, the controller may set the first output to the ground mode and the second output to the current mode for the same duration. Thereafter the controller may select another pair of outputs.

Cable assemblies for providing electrical communication between hinged sections of an electronic device are described. The cable assemblies can include a cover that covers one or more cables that run through a hinge region of the electronic device. The cable and cover can be drawn over a mandrel of the hinge region. The cover and the portions of the mandrel can be visible to a user at the hinge region of the electronic device. The cover can be sufficiently rigid to guide a path of the cable and protect the cable from bending beyond a prescribed angle during rotation of the electronic device at the hinge region. The cover can also be sufficiently rigid to prevent ceasing or folding of the cover and the cable during rotation of the electronic device at the hinge region. The cable assemblies can also include a hinged cover that can be pivoted to close a gap between two hinged sections of the electronic device.

Methods, structures, and apparatus that limit the amount of dendritic growth and metal migration between contacts in order to prevent an erroneous detection of a connection and/or functional failure. One example may reduce dendritic growth and metal migration by limiting an amount of time that a connection detection voltage is applied to CC contacts of a USB Type-C connector when an electronic device is detecting a connection. This and other examples may further limit dendritic growth by not applying the connection detection voltage to the CC contacts for a first duration following a detection of a disconnection.
