20130326206 | REINTIALIZATION OF A PROCESSING SYSTEM FROM VOLATILE MEMORY UPON RESUMING FROM A LOW-POWER STATE - Boot configuration information is stored to a volatile memory of a processing system during a low-power state. When resuming from the low-power state, a processor device accesses configuration information for a memory controller from a non-volatile memory and restores the memory controller using the configuration information so as to permit access to the volatile memory. The processor device then configures the initial contexts one or more processor cores using the core state information maintained by the volatile memory during the low-power state and accessed via the configured memory controller, and the one or more processor cores completes the boot process by executing resume boot code maintained by the volatile memory during the low-power state and accessed via the configured memory controller, rather than accessing boot code from a non-volatile memory. | 12-05-2013 |

20140131139 | Lifting Apparatus - The invention consists of a lifting apparatus. It is designed to enable a user and their mobility assistance device, such as a wheelchair or power scooter, to enter or exit a facility, i.e. residential or commercial, that has at least one step at the en trance. While the invention is in the “lowered” position. the user can move their MAD atop the platform contained in the present invention. While atop the platform, the user can activate the controls and cause the platform to be moved into the “raised” position. The “raised” position moves the user and their MAD upwards and towards the top step of entrance of the facility. The user can then mobilize their MAD and egress off the platform into the facility. If the user desires to exit the facility, the user then reverses the process and enters onto the platform when it is in the “raised” position. The user, while atop the platform, then lowers the platform to its “lowered” position and is able to egress off of the platform. The present invention accomplishes the “raising” and “lifting” functions while utilizing a minimal footprint and impact on existing groundscape. Additionally, the present invention, by design can be easily relocated if the user desires to do so. | 05-15-2014 |
