Abstract: The embodiments set forth techniques for an embedded Universal Integrated Circuit Card (eUICC) to conditionally require, when performing management operations in association with electronic Subscriber Identity Modules (eSIMs), human-based authentication. The eUICC receives a request to perform a management operation in association with an eSIM. In response, the eUICC determines whether a policy being enforced by the eUICC indicates that a human-based authentication is required prior to performing the management operation. Next, the eUICC causes the mobile device to prompt a user of the mobile device to carry out the human-based authentication. The management operation is then performed or ignored in accordance with results of the human-based authentication.

Abstract: A microphone equalization system determines an equalization filter which is used to spectrally shape a signal from a microphone. A loudspeaker has an enclosure, a back volume, a driver diaphragm, and a sensor located inside the back volume. An external microphone is located outside the loudspeaker. A processor determines the equalization filter based on comparison of a first signal from an output of the sensor and a second signal from an output of the external microphone both of which are produced while the driver diaphragm produces acoustic pressure waves produced by the driver diaphragm. The processor is to then spectrally shape a third signal from the output of the external microphone that is responsive to further acoustic pressure waves from a source other than the loudspeaker. Other aspects are also described and claimed.

Abstract: An acoustic module, such as a microphone or speaker module, includes an acoustic membrane that vibrates to produce acoustic waves and an acoustic cavity through which acoustic waves produced by the membrane travel. A liquid removal mechanism removes liquid from the acoustic cavity. Such a liquid removal mechanism may include the acoustic membrane, heating elements, hydrophobic and/or hydrophilic surfaces, and so on. In some cases, the liquid removal mechanism may remove liquid from the acoustic cavity upon connection of the acoustic module and/or an associated electronic device to an external power source.

Abstract: The disclosed embodiments provide a system that uses a first antenna and a second antenna in a portable electronic device. During operation, the system receives a request to switch from the first antenna to the second antenna to transmit a signal to a cellular receiver. Next, the system loads a set of radio-frequency (RF) calibration values for the second antenna. Finally, the system performs the switch from the first antenna to the second antenna to transmit the signal, wherein the second antenna is operated using the RF calibration values after the switch.

Abstract: The embodiments set forth herein disclose techniques for enabling a user device to seamlessly establish a secure, high-bandwidth wireless connection with a vehicle accessory system to enable the user device to wirelessly stream user interface (UI) information to the vehicle accessory system. To implement this technique, a lower-bandwidth wireless technology (e.g., Bluetooth) is used as an initial means for establishing a Wi-Fi pairing between the user device and the vehicle accessory system. Wi-Fi parameters associated with a Wi-Fi network provided by the vehicle accessory system can be communicated to the user device using the lower-bandwidth wireless technology. A secure Wi-Fi connection can then be established between the user device and the vehicle accessory system using the provided Wi-Fi parameters. The embodiments also disclose a technique for enabling the user device to automatically reconnect with the vehicle accessory system in a seamless manner (e.g., when returning to a vehicle).

Abstract: Portable electronic devices having I/O assemblies that can include optical and audio components are described. An exemplary I/O assembly can include a first camera module and a second camera module that can be carried within a camera module housing. A flex connector can carry a strobe that can be positioned between the first camera module and the second camera module. A trim can enclose the first camera, the second camera and the strobe and optically isolates the optical components. An exemplary portable electronic device can include a side wall retainer that defines its perimeter, a front cover glass and a rear cover glass that cooperate to form an enclosure. The I/O assembly can be secured to the enclosure both from inside and outside of the rear cover glass. I/O assembly can also include an audio transducer that can record sound when the camera module are recording videos.

Abstract: A device receives an instruction to authorize a relationship corresponding to communication over a first data connection with a peripheral display unit, and receives authentication data from the peripheral display unit over another data connection. The device then establishes a connection with the peripheral display unit over the first data connection, including providing the authentication information to the peripheral display unit. The device monitors a battery charge level and battery-usage patterns and provides alerts in accordance therewith. The device displays a reconfiguration interface for configuring the user interfaces of one or more peripheral display units, and detects a request to configure an interface of a peripheral. In response to detecting the request, the device displays an updated representation of the peripheral interface, and afterwards transmits instructions to the peripheral to display the user interface in accordance with the request.

Abstract: The embodiments set forth techniques for enabling mobile devices to trigger an electronic Subscriber Identity Module (eSIM) provisioning process. In some embodiments, a main operating system (OS) of the mobile device communicates a provisioning command to an embedded Universal Integrated Circuit Card (eUICC) included in the mobile device. In turn, the provisioning command causes the eUICC to establish a secure channel with a provisioning server. The provisioning command can include, for example, a network address (e.g., a uniform resource locator (URL), Internet Protocol (IP) address, etc.) associated with the provisioning server, an indication of a security protocol to be used for the secure channel, and/or other information. Using this information, the eUICC establishes the secure channel with the provisioning server, whereupon the provisioning server can provision the eSIM to the eUICC over the secure channel.

Abstract: Systems and methods described in this disclosure are related to fabrication and utilization of two-terminal electrical components that may have terminations with reduced width. Components, such as the ones described herein may be used to increase the density of components in electrical devices, as they may reduce a separation distance between devices that lead to solder bridging. Methods for fabrication are also described, including the use of ceramic layers that may provide reduction in parasitic capacitance and/or inductances.

Abstract: A method and structure for stabilizing an array of micro devices is disclosed. The array of micro devices is formed on an array of stabilization posts formed from a thermoset material. Each micro device includes a bottom surface that is wider than a corresponding stabilization post directly underneath the bottom surface.
