Abstract: An electronic device with a display and a fingerprint sensor may authenticate a user for a respective function. While a respective function of the device is in a locked state, the device displays a graphical element on the display, the graphical element indicating a first direction of finger movement that enables unlocking of the respective function. While displaying the graphical element, the device detects an input that includes movement of a finger in the first direction over the fingerprint sensor and determines whether the input meets unlock criteria based at least in part on fingerprint information of the finger detected by the fingerprint sensor during the input. In accordance with a determination that the input meets the unlock criteria, the device unlocks the respective function; and in accordance with a determination that the input does not meet the unlock criteria, the device maintains the respective function in the locked state.

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: Systems and methods for switching between an electronic paper display and a video display are provided. Control circuitry in an electronic device can analyze visual content to determine one or more features of the visual content. For example, the control circuitry can analyze visual content to determine the rate of change and/or color composition of the visual content. Based on the one or more features, the control circuitry can selectively enable the device's electronic paper display or the device's video display.

Abstract: An electronic device may have gaze detection capabilities that allow the device to detect when a user is looking at the device. The electronic device may implement a power management scheme using the results of gaze detection operations. When the device detects that the user has looked away from the device, the device may dim a display screen and may perform other suitable actions. The device may pause a video playback operation when the device detects that the user has looked away from the device. The device may resume the video playback operation when the device detects that the user is looking towards the device. Gaze detector circuitry may be powered down when sensor data indicates that gazed detection readings will not be reliable or are not needed.

Abstract: Systems and methods are provided for selecting one or more of several images captured in sequence and stored in a buffer in response to receiving a user instruction to store a captured image. An electronic device can capture information describing the movement of the device at the time each of the several images was captured, such that each image can be associated with specific device movement information. The electronic device can then select the one of the captured and buffered images for which the movement information of the device satisfies particular criteria. This can ensure that the particular image stored is not blurry due to device movement at the time the image was captured.

Abstract: This is directed to an electronic device having an integrated sensor for detecting a user's cardiac activity and cardiac electrical signals. The electronic device can include a heart sensor having several leads for detecting a user's cardiac signals. The leads can be coupled to interior surfaces of the electronic device housing to hide the sensor from view, such that electrical signals generated by the user can be transmitted from the user's skin through the electronic device housing to the leads. In some embodiments, the leads can be coupled to pads placed on the exterior of the housing. The pads and housing can be finished to ensure that the pads are not visibly or haptically distinguishable on the device, thus improving the aesthetic qualities of the device. Using the detected signals, the electronic device can identify or authenticate the user and perform an operation based on the identity of the user.

Abstract: An air valve includes a valve body and a disc configured to engage a seat. An inlet port is upstream from the seat, and an outlet port is downstream from the seat. A stern is connected to the disc, and a piston is connected to the stern, wherein the piston has first and second positions. A chamber is defined at least in part by the piston and the valve body. A clearance between the valve body and the stem has a first cross-sectional area. One or more relief ports provide fluid communication from the chamber through the valve body and have a combined second cross-sectional area that is greater than or equal to the first cross-sectional area. A method for refurbishing the air valve, as previously described, includes increasing the second cross-sectional area greater than or equal to the first cross-sectional area.

For example, a method for placeshifting media may include sending a first message from a media-receiving electronic device to a media-playing electronic device playing a media file and receiving a response identifying the media file and a point at which the media file was being played when the first message was received. The media-receiving electronic device may play a copy of the media file at the point where the media-playing electronic device left off.
