  • Publication number: 20170033460
    Abstract: An electronic device may have wireless circuitry with antennas. An antenna resonating element arm for an antenna may be formed from conductive housing structures running along the edges of a device. The antenna may have a pair of switchable return paths that bridge a slot between the antenna resonating element and an antenna ground. An adjustable component and a feed may be coupled in parallel across the slot. The adjustable component may switch a capacitor into use or out of use and the return paths may be selectively opened and closed to compensate for antenna loading due to the presence of external objects near the electronic device.

  • Patent number: 9549387
    Abstract: The present techniques relate to reducing interference on conducted RF links by utilizing country information to determine where an electronic device is located, and using such information to select sub-bands or channels that are not available for wireless transmission to be used for transmission of signals via the conducted RF links. Because the conducted RF links operate on frequency bands that are different from the frequency bands used for wireless communications in a given country, there is less likelihood that wireless communications will create interference in the signals being transmitted via the conducted RF links.

  • Publication number: 20160374028
    Abstract: A host device is configured to increase the power output by an internal amplifier of its wireless chipset in response to requests from a remote device. Once the internal amplifier has reached its maximum power, further requests for power increases from the remove device do not similarly lead to automatic power increases being delivered by a external amplifier of the host device. Rather, the host device determines the strength of the link between it and the remote device. If the signal strength is too low, it is an indication that the signal power output by the remote device may not be sufficient to maintain the link and that any further increases in signal power by the host device will have little or no effect on the link. However, if the signal strength from the remote device is sufficient, the host device determines an error rate between it and the remote device. If the error rate is sufficiently low to maintain the link, then the host device will not further increase its signal output power.

  • Patent number: 9519771
    Abstract: This invention is directed to an electronic device with an embedded authentication system for restricting access to device resources. The authentication system may include one or more sensors operative to detect biometric information of a user. The sensors may be positioned in the device such that the sensors may detect appropriate biometric information as the user operates the device, without requiring the user to perform a step for providing the biometric information (e.g., embedding a fingerprint sensor in an input mechanism instead of providing a fingerprint sensor in a separate part of the device housing). In some embodiments, the authentication system may be operative to detect a visual or temporal pattern of inputs to authenticate a user. In response to authenticating, a user may access restricted files, applications (e.g., applications purchased by the user), or settings (e.g., application settings such as contacts or saved game profile).
