  • Patent number: 9095076
    Abstract: An electronic device may have a housing in which electronic components are mounted. The electronic components may be mounted to a substrate such as a printed circuit board. A heat sink structure may dissipate heat generated by the electronic components. The housing may have a housing wall that is separated from the heat sink structure by an air gap. The housing wall may have integral support structures. Each of the support structures may have an inwardly protruding portion that protrudes through a corresponding opening in the heat sink structure. The protruding portions may each have a longitudinal axis and a cylindrical cavity that lies along the longitudinal axis. Each of the support structures may have fins that extend radially outward from the longitudinal axis.

  • Patent number: 9077093
    Abstract: An electrical power adapter employs a magnetically coupled mechanism to retract and deploy prongs used to interface with an electrical receptacle. The magnetically coupled mechanism is linearly displaced by a user, converting the linear displacement to rotary motion, pivoting the retractable prongs between a deployed position and a retracted position. When the retractable prongs are in the deployed position the adapter may be mated with a receptacle and when in the retracted position the adapter has a reduced physical size.

  • Patent number: 9044898
    Abstract: An electronic device may have electronic components enclosed within a plastic housing. The plastic housing may include housing members that are joined using heat activated thermoset polymer film. The heat activated thermoset polymer film may be heated using a metal structure such as a strip of metal that is placed along a joint between the housing members. The temperature of the metal strip and associated layers of the thermoset polymer film may be raised by applying current to the metal strip using an external tool or the electronic components within the housing. Heat activated thermoset polymer film may be heated using a reactive multilayer metal foil. Heat sink layers of metal may be interposed between the reactive multilayer metal foil and the thermoset polymer film. A heated metal ring or a heated edge portion of a plastic housing member may also be used to heat the thermoset polymer film.

  • Publication number: 20150093924
    Abstract: A dual-purpose transformer may be oriented in a plane perpendicular to planes in which printed circuit boards connected thereto are oriented, thereby providing structural support for a framework that can include a dense arrangement of internal power adapter components, in addition to stepping down voltage. Methods for ultrasonic welding are also provided and may be used to concurrently assemble, join and press-fit power adapter housing components. A ground lug is also provided that is shaped and located within a cover piece of a power adapter housing to allow for blind mating with a printed circuit board during an assembly process.

  • Patent number: 8988898
    Abstract: Apparatus that may help identify unauthorized removal of goods while maintaining a pleasing physical appearance, avoiding theft misidentifications, and allowing a high degree of customer interaction. One example may provide a signal path for conveying a signal that is active when a good or device is removed from a retail or other environment in an authorized manner. The signal path may be wired or wireless. In another example, a signal path for a sensor may be inconspicuously combined with a power cable. In another example, theft misidentifications may be prevented by not relying on connections that a customer is likely to interact with to detect a theft. Another example may provide a security device that may allow a high degree of customer interaction by unobtrusively attaching a sensor to the back of a good to be protected.

  • Patent number: 8920189
    Abstract: A power adapter including a wing deployment mechanism for retaining a wing in a first undeployed position and the second deployed position. One example may provide a housing, a spring, a spring cover, and the wing. In one example, the wing may be pivotally attached to the housing and the spring and the spring cover may be fixedly attached to the housing. The spring may contact a portion of the wing and may, in one example, apply a position dependent force to the wing that biases the wing towards either the first or the second position.

  • Publication number: 20140277643
    Abstract: Methods, systems, and apparatus for selectively communicating data and audio over a limited-size audio plug. A host device determines whether an audio accessory or a data communicating accessory is plugged therein via a signal, or lack thereof, communicated to the host device via the audio plug of the accessory. The host device then either communicates audio or data over the audio plug contacts that are typically used only for audio communication based on whether its connected to an audio accessory or data communicating accessory. An audio plug may also include a split-ring contact where multiple, independent contacts are formed in place of a single tip, ring, or sleeve contact. The split-ring contact may be used for communicating audio and/or data.

  • Publication number: 20140265763
    Abstract: Systems and methods of providing a tooling system for forming a unitary housing are disclosed herein. One embodiment may utilize a plurality of injection cavity slides. The slides may form the interior cavity of the housing. Utilizing a plurality of injection cavity slides to form a single cavity insert may allow the slides to be remove from an opening in the housing which is smaller than the cavity of the housing. Removing the slides from housing allows for the formation of housing having a unitary structure.

  • Publication number: 20140256186
    Abstract: Various embodiments of low profile male connectors are described. In one embodiment, a connector includes a plug housing having a depth and an interior cavity designed to accommodate pins that extend within the interior cavity in a direction of the depth. The plug housing may be designed to be fully insertable into a receptacle connector of an electronic device, and to have a rear surface that conforms with a shape of an exterior surface of the electronic device. The pins arranged in the plug housing may include various features, such as connecting portions protruding from the plug housing at an angle of approximately 90 degrees for coupling to a cable, bases including cutouts for extending a length of an elongated shaft of the pin, barbs for engaging the plug housing, and limit stops for distributing a force applied to the elongated shaft upon engagement with a receiving pin.

  • Patent number: 8782869
    Abstract: A connector of a cable (e.g., a 30-pin connector) can be used to facilitate various security-related and other functionalities. For example, a connector can include security locking mechanisms for engaging or locking the connector to a portable electronic device. A connector can additionally support the transmission of security signals, data signals, power, and/or the like. An unlocking tool can be used to disengage a connector locked to the portable electronic device. More specifically, the unlocking tool can be applied to a connector and cause the locking mechanisms of the connector to release such that the connector can be freely disconnected from a connected portable electronic device.
