    Abstract: Handheld electronic devices are provided that contain wireless communications circuitry having at least first and second antennas. An antenna isolation element reduces signal interference between the antennas, so that the antennas may be used in close proximity to each other. A planar ground element may be used as a ground by the first and second antennas. The first antenna may be formed using. a hybrid planar-inverted-F and slot arrangement in which a planar resonating element is located above a rectangular slot in the planar ground element. The second antenna may be formed from an L-shaped strip. The planar resonating element of the first antenna may have first and second arms. The first arm may resonate at a common frequency with the second antenna and may serve as the isolation element. The second arm may resonate at approximately the same frequency as the slot portion of the hybrid antenna.

    Abstract: Diese Offenbarung betrifft Systeme, Verfahren und Vorrichtungen zur Begrenzung oder Drosselung einer Aktivität einer Zubehörvorrichtung, welche kommunikativ zu einer Computervorrichtung gekoppelt ist. Die Aktivität der Zubehörvorrichtung ist eingeschränkt oder gedrosselt, um elektromagnetische Interferenz zu reduzieren und die Signalqualität einer Drahtloskommunikation, in welcher die Computervorrichtung teilnimmt, zu verbessern. In einigen Ausführungsformen kann eine Entscheidung zu drosseln auf einem Batterieladeniveau der Computervorrichtung basieren. Zum Beispiel ist in einigen Ausführungsformen die Zubehörvorrichtung ein zusätzliches Batterieladegerät, eingerichtet, um der Computervorrichtung Strom bereitzustellen, wenn eine Steckdose nicht sofort verfügbar ist. Wenn die Signalqualität eines Telefonanrufs von der Computervorrichtung verringert ist oder der Benutzer in einem Bereich niedriger Signalabdeckung ist, kann das zusätzliche Batterieladegerät eingeschränkt oder gedrosselt werden, um Interferenz zwischen dem zusätzlichen Batterieladegerät und der Computervorrichtung zu verhindern.

    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).

    Abstract: Abstract of the Disclosure Electronic devices are provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry and antenna structures. A parallel 5 fed loop antenna may be formed from portions of a conductive bezel and a ground plane. The antenna may operate in multiple communications bands. The bezel may surround a peripheral portion of a display that is mounted to the front of an electronic device. The bezel may 10 contain a gap. Antenna feed terminals for the antenna may be located on opposing sides of the gap. A variable capacitor may bridge the gap. An inductive element may bridge the gap and the antenna feed terminals. A switchable inductor may be coupled in parallel with the 15 inductive element. Tunable matching circuitry may be coupled between one of the antenna feed terminals and a conductor in a coaxial cable connecting the transceiver circuitry to the antenna.

    Abstract: Apparatus and methods for authenticating and granting a client device (e.g., cellular telephone) access to a network. In one embodiment, a network service provider such as a cellular telephone company may distribute user access (e.g., Universal Subscriber Identity Module or "USIM") credentials to a services manager via a USIM vendor. The services manager may maintain a list of authorized users. A user at a client may authenticate to the services manager. Once authenticated, the services manager may provide the user with a set of USIM credentials. When the user desires to use wireless network services, the user equipment may establish a wireless link between the user equipment and the network service provider. During authentication operations, the user equipment may use the USIM credentials to authenticate to the network service provider. Following successful authentication, the network service provider may provide the user equipment with wireless services.
