Abstract: In some examples, an optical encoder may consist of a light source that shines light onto a wheel which then reflects the light onto a sensor. Using information encoded in the reflected light, the rotation of the wheel may be determined. In some examples, rotation of the wheel may be determined by detecting an encoding pattern in light reflected from an exterior surface of the wheel. In some examples, the encoding pattern can be a pattern of light and dark stripes. In some examples, a pattern of light stripes can be generated from light reflecting off of reflective portions of the wheel. Some examples of the disclosure relate to using a surface topology for a wheel that can be used to generate an encoding pattern of light and dark stripes in light reflected from the surface of the wheel, even when the surface of the wheel is uniformly reflective.

Abstract: An electronic device with a touch-sensitive surface, a display, and tactile output generator(s) displays a user interface including a moveable component representing a plurality of selectable options.

As the first moveable component moves through the first selectable option with a speed: the device generates a tactile output and an audio output. As the moveable component moves through the second selectable option with a slower speed: the device generates a different tactile output in a first property but is the same in a second property and generates a different audio output.

The second loop includes a second converter with a first order series RC filter to reduce the second loop's response time. A second current mirror receives current from the second converter and generates a dynamically adapting feedback current, which flows through the resistor in the first loop.

Abstract: A pool of devices is initially associated under a single product type identifier, for example, a single stock keeping unit (SKU) identifier. Each device is associated with a secure element (SE), for example, an embedded universal integrated circuit card (eUICC). A wireless telecommunications carrier purchases a subset of the devices from the owner of the pool of devices.

The eSIM delivery server reserves eSIMs for the purchased devices. When an end user buys one of the devices from the subset, the purchased device is provisioned by the eSIM delivery server with the eSIM reserved for that device.

Abstract: Methods, devices, and servers for as-needed update of a trusted list are provided herein. An electronic subscriber identity module (eSIM) server receives a request for an eSIM of a particular type from a wireless device. The eSIM server evaluates the particular type and requests an eSIM of the particular type from a second eSIM server, which is not initially trusted by a secure element (SE) of the wireless device. The eSIM server sends a policy update to the wireless device. The wireless device passes the policy update to the SE, for example, a universal integrated circuit card (UICC). The UICC updates the trusted list with an identity of the second eSIM server. When the wireless device downloads a bound profile package (BPP) containing an eSIM from the second eSIM server, the UICC validates the BPP based on the updated trusted list. The eSIM is then installed on the UICC.

Abstract: A digitally stored map can indicate the signal quality for each of the map's regions. A device can determine its location, speed, and direction using global positioning system (GPS) and other sensors. Based on this information, the mobile device can predict a field of locations within which the device will probably be located within a specified future time frame. Based on both the information indicating signal quality and the probable future field of locations, the device can estimate a moment at which the device will probably begin to suffer from low-quality or absent signal. Using this prediction, the device can proactively perform a variety of anticipatory remedial actions. For example, the device can begin allocating a greater portion of currently available wireless network communication bandwidth to the reception of data packets that represent content that is being streamed to the device, so that the device can proactively buffer those packets.

Abstract: Pressure compensation can be used to improve performance of force-sensitive touch screens. Changes in pressure, particularly transient, internal pressure changes in an electronic device due to an object applying force to a touch screen of the electronic device, can degrade force sensing performance of the touch screen. For example, when a finger presses a force-sensitive touch screen of a sealed electronic device, the applied force can increase internal pressure of the sealed electronic device until internal pressure can equalize. The increased internal pressure can cause a normal force to oppose the deflection of the touch screen, resulting in inaccurate force measurements of applied user force. In some examples, an electronic device including a force-sensitive touch screen can include a pressure sensor configured to measure internal pressure of the electronic device. The measured pressure can be used to compensate the amount of force measured by the force sensor.

In response, the wireless device may transmit a second transmission occupying the second frequency band concurrent with the first transmission. The wireless device may set a duration of the second transmission based at least in part on a determination of whether the second wireless device is configured to assess the state of all frequency bands within the operating bandwidth before beginning a subsequent transmission.

Abstract: A context-aware voice guidance method is provided that interacts with other voice services of a user device. The voice guidance does not provide audible guidance while the user is making a verbal request to any of the voice-activated services. Instead, the voice guidance transcribes its output on the screen while the verbal requests from the user are received. In some embodiments, the voice guidance only provides a short warning sound to get the user's attention while the user is speaking on a phone call or another voice-activated service is providing audible response to the user's inquires. The voice guidance in some embodiments distinguishes between music that can be ducked and spoken words, for example from an audiobook, that the user wants to pause instead of being skipped. The voice guidance ducks music but pauses spoken words of an audio book in order to provide voice guidance to the user.
