Abstract:
An electronic device may be provided with antenna structures. The antenna structures may be formed using a dielectric carrier structure such as a speaker enclosure, so that interior space within the electronic device that is occupied by a speaker can be used in forming an antenna. A speaker driver may be mounted in the speaker enclosure. Openings in the speaker enclosure may allow sound from the speaker driver to be emitted from the speaker enclosure. The antenna structures may have first and second loop antenna resonating elements. The first loop antenna resonating element may indirectly feed the second loop antenna resonating element. The second loop antenna resonating element may be a distributed loop element formed from a strip of metal with a width that loops around the speaker enclosure. Openings in the second loop antenna resonating element may be aligned with the speaker enclosure openings.
Abstract:
An electronic device may have a display. A display cover layer and a transparent inner display member may overlap a display pixel layer. The display pixel layer may have an array of display pixels for displaying images for a user. A touch sensor layer may be interposed between the display pixel layer and the transparent display member. A ferromagnetic shielding layer may be mounted below the display pixel layer. A flexible printed circuit containing coils of metal signal lines that form a near-field communications loop antenna may be interposed between the ferromagnetic shielding layer and the display pixel layer. A non-near-field antenna such as an inverted-F antenna may have a resonating element mounted on an inner surface of the display cover layer. The resonating element may be interposed between the transparent display member and the display cover layer.
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 service 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.
Abstract:
In order to establish a connection between electronic devices, after receiving an advertising packet from another electronic device, an electronic device compares a performance metric associated with the communication with the other electronic device with a threshold value. Based on the comparison, the electronic device provides pairing-intent information specifying a pairing intent for the electronic device and the other electronic device for presentation by the other electronic device. Moreover, after receiving additional pairing-intent information specifying the pairing intent from the other electronic device, the electronic device establishes the connection with the other electronic device when the additional pairing-intent information matches the pairing-intent information. For example, the pairing intent may include a gesture and/or a sequence of one or more characters, and the additional pairing-intent information may include: the sequence of one or more characters; accelerometer data corresponding to the gesture; and/or user-interface data corresponding to the gesture.
Abstract:
In order to improve communication with another electronic device, during an advertising mode an electronic device (such as a smartphone) may transmit a packet with advertising information using a default transmit power level. Then, based on feedback about a performance metric associated with the communication from the other electronic device, the electronic device may selectively increase the transmit power level for a subsequent packet. Because this selective increase in the transmit power level may increase the overall power consumption, the change in the transmit power level may depend on a battery power level of the electronic device. However, the selective increase in the transmit power level may decrease the overall power consumption by reducing or eliminating retries.
Abstract:
Dynamic antenna switching based on weighted signal to noise ratio (SNR). A wireless device may include multiple antennas. SNR at each active antenna may be calculated. An antenna-specific weight may be applied to each antenna's SNR. The antenna-specific weights may further be radio specific and/or transmit or receive specific in some cases. Antenna selection (possibly just for a specific radio and/or for transmit or receive operations, depending on the specificity of the antenna weights), including potentially switching which antenna is used, may be based on the resulting weighted SNR values for each antenna. If the antenna-specific weights are radio specific and/or transmit or receive operation specific, the method may be performed multiple times with different antenna-specific weights to select antenna(s) for different radios and/or for other operations.
Abstract:
An electronic device may be provided with wireless circuitry. Control circuitry may be used to adjust the wireless circuitry. The wireless circuitry may include antennas that are tuned, adjustable impedance matching circuitry, antenna port selection circuitry, and adjustable transceiver circuitry. Wireless circuit adjustments may be made by ascertaining a current usage scenario for the electronic device based on sensor data, information from cellular base station equipment or other external equipment, signal-to-noise ratio information or other signal information, antenna impedance measurements, and other information about the operation of the electronic device.
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:
An electronic device having at least one operational setting, such as a power setting, with at least a first state and a second state. The electronic device may also include an access controller that can receive state data and authorization data from an external source such as a remote control. The access controller may enable a state of the operational setting upon receipt of proper authorization data received from or related to the output from at least one biometric sensor associated with the remote control.
Abstract:
An electronic device receives data associated with at least one biometric detected by a sensor of a remote control device. The biometric may be at least one fingerprint, retinal scan, facial image, and/or any other biometric. A profile for a user associated with the data is determined out of a number of possible profiles based on the data. The electronic device is then configured in one or more ways according to the determined user profile. Such configuration may include any way that the electronic device may be personalized and/or otherwise altered. In this way, an electronic device may provide a personalized experience for a number of different users without burdening and/or annoying the respective users.
