| 20120250665 | Method and system for maintaining concurrent membership in multiple networks from a single wireless modem - Method and system for maintaining concurrent membership in multiple networks from a single wireless modem on a wireless networking device. The device time-multiplexes between the networks according to time slots allocated to each network that are shorter than the membership timeout period for the other network. Moreover, whenever the device switches between the networks, the device resets the modem and rejoins the other network using configuration information stored in a nonvolatile memory when the network being rejoined was previously quit. Each network remains unaware of the device's membership in the other network and regards the absence of transmission from the device during the time slot allocated to the other network as a temporary loss of radio contact rather than a membership termination event. The invention enables a single-modem wireless networking device to maintain concurrent ZigBee sessions on a smart energy network and a home automation network. | 10-04-2012 |
| 20120311317 | Access-controlled customer data offloading to blind public utility-managed device - A method and system for access-controlled customer data offloading uses a blind public utility-managed device. A customer-managed device encrypts collected customer data using per-type, per-period keys and transmits the encrypted customer data to the utility-managed device. The customer-managed device further encrypts the per-type, per-period keys using a master key and transmits the encrypted per-type, per-period keys to the utility-managed device. When the current period ends (e.g., each day at midnight), the customer-managed device generates new per-type, per-period keys and continues the above customer data offloading using the new per-type, per-period keys. As a result, the customer offloads storage of customer data to the public utility without relinquishing control over access to the customer data. Moreover, the fact that the customer data are encrypted by data type and period allows the customer to access and expose the customer data in highly granular fashion. | 12-06-2012 |

| 20100083018 | FAN SPEED CONTROL OF SILICON BASED DEVICES IN LOW POWER MODE TO REDUCE PLATFORM POWER - In general, in one aspect, the disclosure describes running a cooling fan within a computer at low speed while the computer is in low temperature operations (e.g., idle). The operation of the cooling fan may reduce processor (CPU) temperature enough to decrease processor leakage power, offsetting the power consumption of the fan, and possibly resulting in a net system power reduction. The benefit at the platform level increases further when considering the low efficiency of voltage regulation (VR) in this lower power regime, and potentially reductions in other components (e.g., graphics processor). The optimal fan speed is the speed at which the overall system power is reduced the most (e.g., processor power savings is greater than fan power utilized). The optimal temperature may be determined dynamically during operation or may be determined in manufacturing and applied statically during operation. | 04-01-2010 |

In one embodiment of the invention, the processing unit dynamically changes the strength of the On-Die Termination pull-up/pull-down resistance based on the memory operating mode, memory voltage, and memory temperature. | 09-27-2012 |
| 20120311590 | RESCHEDULING ACTIVE DISPLAY TASKS TO MINIMIZE OVERLAPPING WITH ACTIVE PLATFORM TASKS - In general, in one aspect, a mobile device display includes panel electronics, a backlight driver and a rescheduler. The panel electronics is to generate images on an optical stack of the display based on input from a processing platform of the mobile device. The backlight driver is to control operation of a backlight used to illuminate the optical stack so that the user can see the images generated on the display. The rescheduler is to determine when a timing critical task of the processing platform overlaps with a non-timing critical task of the panel electronics or the backlight driver and reschedule the non-timing critical task until the timing critical task is inactive or a visual tolerance limit has been reached. The rescheduling minimizes overlap between the timing critical tasks and non-timing critical tasks and accordingly reduces power consumption without effecting performance or impacting a user's visual experience. | 12-06-2012 |
