  • Method and system for detecting moisture on a connector contact
    Patent number: 10591430
    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.
    Type: Grant
    Filed: September 8, 2017
    Date of Patent: March 17, 2020
    Assignee: Apple Inc.

  • Battery cell with an integrated pouch metal foil terminal
    Patent number: 9136509
    Abstract: A battery includes a battery cell having a pair of cell electrodes that are encased in a laminated pouch. The laminated pouch has a conductive moisture barrier layer that is sandwiched between respective electrically insulating layers. Several terminals are integrated with the pouch, including a first terminal and a second terminal that are directly connected to the first and second cell electrodes, respectively, and a third terminal that is directly connected to the conductive moister barrier layer. Other embodiments are also described and claimed.
