Abstract: An item-providing system supplies items to a user device for consumption at the user device via communication infrastructure. The device may correspond to a book reader device or other type of device. The item-providing system uses a content delivery module to deliver the items to the user device.

Abstract: A detection device may monitor emissions from a computing device, which may include radiation and/or radio waves from a computing device. The emissions may be electromagnetic (EM) radiation indicative of operation of components of the computing device. When the emissions reach or exceed an emissions threshold, the detection device may output an indicator. The indicator may indicate a violation of an operational policy that is associated with the emissions threshold. The indicator may additionally or alternatively indicate compliance with the operation policy. In some embodiments, the detection device may be implemented as an accessory such as a case, a cover, a light, or another type of accessory for the computing device.

Abstract: An item-providing system supplies items to a user device for consumption at the user device via communication infrastructure. The device may correspond to a book reader device or other type of device. In one illustrative case, the item-providing system and the user device include functionality for providing upgrade-related items to the user device in a transparent manner. The item-providing system and the user device also include testing functionality.

Abstract: A computing device may operate in various modes, which may include a full operational mode and a reduced operational mode. When operating in the reduced operational mode, the computing device may reduce power, reduce radiation output, and/or power off various components to achieve operation in accordance with an operational policy. While operating in the reduced operational mode, the computing device may restrict user access to or adjustment of the impacted components thereby preventing the user from restoring the computing device to the full operational mode, at least temporarily. In some aspects, the device may initiate or terminate the reduced operational mode in response to a signal from a beacon, parameters from a monitored environment, or in response to user commands. In various aspects, the device may provide messaging to inform the user about the modes of operation.

Abstract: In some embodiments, a distance between the at least one light sensor and the surface may be calculated using a ratio representative of the phase difference using time-of-flight of light. The distance may be within a distance range defined by a distance of light travel during a modulation period of the predetermined frequency. The distance may be based on the ratio defined by an amount of energy stored from captured light during a first time interval and a second time interval, and a comparison of an amount of light stored from captured light during at least a third time interval. The first, second, and third time intervals are different, but may overlap in some instances. In some embodiments, the amount of ambient light may be identified and subtracted from the inputs of the ratio. A switch may be used to prevent oversaturation of a storage element storing the stored energy.

Abstract: Described are systems and methods for content-adaptive presentation of content. A presentation profile for use in presentation of content is determined based at least in part on one or more determination characteristics. The determination characteristics may include metadata descriptive of the content, such as genre, style, artist, and so forth. The presentation profile may include equalizer settings, overall amplitude or volume, speaker configuration, and so forth.

Abstract: A handheld electronic book device is configured with dual displays. The device includes a first display for presenting visible representations of textual or graphic content related to the electronic book. The device also includes a second display positioned alongside the first display. The second display includes a plurality of graphic elements that correspond to portions of the first display. Also, the second display is responsive to user input to one of the graphic elements to perform an action on the content that is shown in the portion of the first display that corresponds to the one element.

Abstract: A user can provide input to a computing device through various combinations of speech, movement, and/or gestures. A computing device can analyze captured audio data and analyze that data to determine any speech information in the audio data. The computing device can simultaneously capture image or video information which can be used to assist in analyzing the audio information. For example, image information is utilized by the device to determine when someone is speaking, and the movement of the person's lips can be analyzed to assist in determining the words that were spoken. Any gestures or other motions can assist in the determination as well. By combining various types of data to determine user input, the accuracy of a process such as speech recognition can be improved, and the need for lengthy application training processes can be avoided.

Abstract: An item-providing system supplies items to a user device for consumption at the user device via communication infrastructure. The device may correspond to a book reader device or other type of device. In one illustrative case, the item-providing system may send a notification message to the user device to notify the user device to wake up and perform one or more actions. The item-providing system may provide scheduling functionality for determining the timing at which to send the notification message.
