Abstract: Contact structures that are readily manufactured, where contacts in the contact structures consume a minimal amount of surface area, depth, and volume in an electronic device.

Abstract: Contacts that may be highly corrosion resistant, may be readily manufactured, and may conserve precious materials. One example may provide contacts having a layer of a precious-metal alloy to improve corrosion resistance. The precious-metal-alloy layer may be plated with a hard, durable, wear and corrosion resistant plating stack for further corrosion resistance and wear improvement. The resources consumed by a contact may be reduced by forming a bulk or substrate region of the contact using a more readily available material, such as copper or a material that is primarily copper based.

Abstract: A dual subscriber identity module (SIM) card connector is provided that includes a lower connector housing portion having a bottom surface and an upper connector housing portion having a top surface. The upper connector housing portion is coupled to the lower connector housing portion to define an opening for a receiving space between the upper and lower connector housing portions. The opening and receiving space are sized and shaped to slidably receive a SIM card tray. The connector includes a first plurality of electrical contacts disposed at the bottom surface of the lower connector housing portion and configured to make contact with a first SIM card disposed on a first side of the SIM card tray when the tray is received within the receiving space.

Abstract: A case a portable listening device. The case includes a housing having an interior space to receive the portable listening device; a lid attached to the housing; a rechargeable battery and first and second wireless power receiving elements configured to receive electric charge from a wireless power transmitter during a charging event. The case further includes switching circuitry that is configured to disable one of the first or second wireless power receiving elements during a charging event when the disabled element is receiving power less efficiently than the other element.

Abstract: A method of applying a dielectric lubricant to an electrical connector of a consumer electronic device. The method includes inserting a dielectric lubricant delivery device apertures for delivering the dielectric lubricant to the electrical connector into a receptacle of the electronic device; applying pressure to a chamber including the dielectric lubricant, the chamber being fluidly coupled to the apertures of the lubricant delivery device such that the pressure causes the lubricant to enter the receptacle via the apertures and deposit on contacts of the electrical connector; and pulling vacuum using the lubricant delivery device to remove excess dielectric lubricant from the receptacle and the electrical connector.

Abstract: A waveguide structure to allow device to determine its orientation are disclosed. The waveguide may be formed of a dielectric core and a cladding. The dielectric core may be formed of a solid dielectric material that conducts radio waves at millimeter wave frequencies and above. The cladding may encapsulate the core, and may include at least two conductive portions. Each conductive portion may be disposed around less than the entire core. The conductive portions allow electrical signals to flow between two devices to determine an orientation of the waveguide.

Abstract: A voltage of a first pin that is one of several pins of an external connector of a system is measured, while the first pin is un-driven except for being pulled to ground through a first resistance, and a second pin of the external connector is being used as a power supply rail of the system. The measured voltage is compared to a short circuit threshold and in response to that threshold being exceeded, the power supply voltage on the second pin is reduced. In such an embodiment, no test stimulus needs to be applied to any of the pins of the external connector. Other embodiments are also described and claimed.

Abstract: A unidirectional cable connector that can be operatively connected between a host device and accessory device in the ecosystem of products. The cable includes first and second plug connectors at opposite ends of a wire where the two plug connectors share a common pinout but the insertion plug of the second connector is shortened in length as compared to the insertion plug of the first connector. The shortened plug prevents the second connector from being fully inserted into the host device that includes a standard depth receptacle connector, and thus prevents the second connector from being operatively coupled to the host device. The shortened plug can, however, be operatively connected with an electronic device having a shortened receptacle connector according to embodiments of the disclosure.
