H01Q 1/24
H01Q 1/42

US Classification:

343702, 343789

Abstract:

An electronic device may have a housing with conductive housing walls. A dielectric antenna window may be formed in an opening in one of the conductive housing walls. A dielectric logo may form the dielectric antenna window. A dielectric support structure may have an outline that matches the dielectric logo. An antenna resonating element for an antenna may be formed on the dielectric support structure. An antenna cavity for the antenna may be formed by a conductive cavity structure. A pattern of voids in the dielectric support structure may reduce dielectric loading for the antenna. The conductive cavity structure may be formed from solderable plated metal. The conductive cavity structure may have a planar lip that is attached to the conductive housing walls using conductive adhesive. Rear wall portions of the conductive cavity structure may be oriented at a non-perpendicular non-zero angle with respect to the planar lip.

International Classification:

H04L 9/32

US Classification:

726 16

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).

Appl. No.:

12/577128

Inventors:

Matt A. Mow - Los Altos CA, US
Robert W. Schlub - Campbell CA, US
Ruben Caballero - San Jose CA, US

International Classification:

G01R 29/08

US Classification:

343703

Abstract:

A test system for testing multiple-input and multiple-output (MIMO) systems is provided. The test system may convey signals bidirectionally between two test chambers. Each test chamber may be lined with foam to minimize electromagnetic reflections. Each test chamber may include structure three-dimensional array of test antennas. The test antennas may be mounted in a sphere using an antenna mounting structure. The antenna mounting structure may include multiple rings of different sizes. Test antennas may be embedded in the inner walls of the antenna mounting structure. There may be multiple receiving antennas located in each test chamber. One test chamber may include a device under test inside an array of test antennas and another test chamber may include base station antennas inside another array of test antennas. Signals may be conveyed between the test chambers using channel emulators.

International Classification:

H04W 12/06
H04W 88/06

US Classification:

455411

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.

Ruben Caballero - San Jose CA, US

International Classification:

G06F 19/00

US Classification:

702120

Abstract:

A wireless electronic device may serve as a device under test in a test system. The test system may include an array of over-the-air antennas that can be used in performing over-the-air wireless tests on the device under test (DUT). A channel model may be used in modeling a multiple-input-multiple-output (MIMO) channel between a multi-antenna wireless base station and a multi-antenna DUT. The test system may be configured to perform over-the-air tests that emulate the channel model. A design and analysis tool may be used to identify an optimum over-the-air test system setup. The tool may be used in converting a geometric model to a stochastic model for performing conducted tests. The tool may be used in converting a stochastic model to a geometric model and then further convert the geometric model to an over-the-air emulated stochastic model. The over-the-air emulated stochastic model may be used in performing conducted tests.

US Classification:

4555757, 343745

Abstract:

An electronic device has wireless communications circuitry including an adjustable antenna system coupled to a radio-frequency transceiver. The adjustable antenna system may include one or more adjustable electrical components that are controlled by storage and processing circuitry in the electronic device. The adjustable electrical components may include switches and components that can be adjusted between numerous different states. The adjustable electrical components may be coupled between antenna system components such as transmission line elements, matching network elements, antenna elements and antenna feeds. By adjusting the adjustable electrical components, the storage and processing circuitry can tune the adjustable antenna system to ensure that the adjustable antenna system covers communications bands of interest.

Abstract:

Electronic devices may include radio-frequency transceiver circuitry and antenna structures. The antenna structures may include antenna resonating elements such as dual-band antenna resonating elements that resonate in first and second communications bands. The antenna structures may also contain parasitic antenna elements such as elements that are operative in only the first or second communications band and elements that are operative in both the first and second communications bands. The antenna resonating elements and parasitic elements may be mounted on a common dielectric carrier. The dielectric carrier may be mounted within a slot or other opening in a conductive element. The conductive element may be formed from conductive housing structures in an electronic device such as a portable computer. The portable computer may have a clutch barrel with a dielectric cover. The dielectric cover may overlap and cover the slot and the dielectric carrier.
