Abstract: An electronic book distribution system includes electronic devices that reset their passcodes after specified authentication failures. The passcodes of an individual electronic device is reset to a value that is generated using a predefined function of a randomly generated support code. The support code is displayed to the user, and the user is instructed to contact a support service in order to obtain the new passcode. The support service independently authenticates the user, calculates the new device passcode using the same predefined function used by the electronic device, and provides the new passcode to the user.

Abstract: The techniques disclosed herein allow a user to synchronize the playing and displaying of digital content on an electronic device. The device may render a first portion of digital content so it may be displayed. The device may also play a segment of the digital content as audio using text to speech software. The device may also render a second portion of digital content for display depending on whether the position of the last word read is greater than the last position in the first portion of digital content.

Abstract: A sharing service receives a request to store a media item stored on an electronic book reader device for sharing with one or more other content rendering devices. In response, the sharing service associates a pass phrase with the request. The sharing service then provides the media item to those devices (e.g., eBook reader devices) that provide the pass phrase to the sharing service within a predetermined amount of time.

Abstract: A processing device receives a schedule from a server, the schedule identifying delivery times for a set of items associated with the user device. At each delivery time, the processing device contacts the server to obtain one or more items from the server in accordance with the schedule.

Abstract: Power consumption while in a low power suspend mode is enhanced by placing a portion of suspend and resume instructions into internal rewriteable memory, such as internal random access memory (“IRAM”). During entry into suspend, control is transferred from instructions stored in an external memory to instructions stored within the internal rewriteable memory. These instructions are configured to reduce power consumption of the external memory by reducing a slew rate, drive strength, and so forth. Upon awakening from suspend, the instructions within the internal rewriteable memory place the external memory back to an operational state and control passes back to the instructions stored within external memory.

Abstract: A quiescent doze mode permits significant reductions in power consumption and dissipation by electronic devices while idle without producing adverse latencies to users. Device drivers communicate predictions as to future use of their coupled devices with a kernel. The kernel may then enter a quiescent doze mode comprising gating clocks on the processor and peripherals, disabling interrupts, and executing a wait for interrupt. Dynamically increasing timer interrupt intervals to significant fractions or multiples of a second further increases the percentage of time the device remains in quiescent doze mode.

Abstract: A low-power mode for interfaces, such as secure digital input/output (SDIO) interfaces, is described. The low-power mode provides significant power savings while allowing rapid resumption of data transfer on the interface. The SDIO low-power mode gates an SDIO clock and transitions the SDIO bus to a 1-bit mode. One line of the bus carries the 1-bit data while another line carries interrupts from an SDIO peripheral. Normal data transmission results in enabling the SDIO clock and setting the bus set to the 4-bit mode.

Abstract: A server creates a schedule for each of multiple user devices based on a set of items associated with a corresponding user device, and allows each user device to obtain associated items in accordance with the schedule.

Abstract: An electronic device in a low power mode, for example an eBook reader device, may use a fast awake module to quickly update a display. The electronic device may receive an interrupt, begin to awaken, present a cached pre-rendered image on the display, and may resume the low power mode or pre-render additional images to refill the cache before resuming the low power mode.

Abstract: Some implementations provide power management techniques for an electronic device that receives power through a USB port. The device may receive power from various different power sources such as a PC, USB hub, and various types of power adapters. To identify a type of power adapter connected to the USB port, the device's USB device controller may be reconfigured to operate in a host mode. A pull-up or pull-down may be placed on one of the D+ or D? lines of the USB port for determining whether the lines are shorted or floating. When the lines are shorted, the power source may be identified as a first type of power adapter that provides a known level of current. When the lines are not shorted, the values of the lines may be compared with known values for one or more pull-ups or pull-downs to attempt to identify other known power adapters.

Abstract: A device controller, such as a universal serial bus (“USB”) device controller, that is unattached to an external device is placed into a low power mode. During low power mode, interface components of the device controller are gated or placed into a reduced power state. For example, components such as a USB gadget PHY, which manages physical layer communication, USB direct memory access clock, secondary clocks, and so forth may be gated. Upon receiving a connection event indicating attachment of a device to the USB, the device controller resumes normal power operation. This device controller low power mode may work in conjunction with state retention modes or other low power modes affecting other components within an electronic device.
