Abstract: An electronic device includes a flexible display. A device housing provides a translation surface for the flexible display. A rotor positioned within a curvilinear section of the flexible display rotates with translation of the flexible display across the translation surface. The rotor can be a rechargeable electrochemical cell, can be a rechargeable electrochemical cell situated within a sheath, or can be positioned within a housing defining an outer surface of the rotor to save space within the electronic device.

Abstract: One disclosed method includes generating a rule set by an application running on a primary processor. The rule set specifies how the application handles events. The rule set is sent from the primary processor to a secondary processor and the primary processor is placed in sleep mode. The secondary processor may then handle at least one event corresponding to the application by executing the rule set while the primary processor is in sleep mode. In one embodiment, handling the event may include substituting for the application by the secondary processor by executing the rule set, and controlling a peripheral hardware device that is peripheral to the primary processor according to the rule set. Handling an event may also include waking the primary processor from sleep mode by the secondary processor and passing control back to the primary processor.

Abstract: One disclosed method includes communicating with a kernel running on a primary processor, by a second processor, in response to detection of a state change; performing a hardware operation, in response to the state change, using the kernel without waking user space on the primary processor, where the user space remains suspended; and resuming a sleep mode of the primary processor by suspending the kernel after the hardware operation is completed. One example of a hardware operation is modification of display data on a touchscreen display. The method of operation may perform the hardware operation using the kernel without waking hardware drivers other than a hardware driver related to the hardware operation.

Abstract: In embodiments of display co-processing, a computing device includes a display, a full-power processor, and a low-power processor that can alter visual content presented by the display without utilizing the full-power processor. The low-power processor can, responsive to a request from the full-power processor, generate additional display data to update display data stored in a frame-buffer of the display. The low-power processor can then transmit the additional display data to the frame-buffer effective to alter at least a portion of the visual content presented by the display. In some embodiments, the additional display data is transmitted via a protocol converter that forwards the display data to the display using a display-specific communication protocol.
