The present disclosure describes technologies and techniques for use by a data storage controller (such as a non-volatile memory (NVM) controller) to emulate hardware registers in software and/or firmware.

In this manner, new hardware registers added to an NVM standard may be implemented by software and/or firmware rather than hardware. Hence, the NVM controller may comply with new standard requirements without changing the hardware. NVMe examples are provided. |

Drywall lifting tool
The PB-DSR tool is a lightweight tool weighing approximately two pounds that construction workers who hang drywall (or plywood) can use to roll the heavy material from the ground to the workers on a scaffold instead of lifting it by himself using his back, arms and legs, which causes injuries. The worker on the ground stands the drywall or other material on end, leans it against the roller, and rolls it upwards to the person on the scaffold instead of lifting the drywall up to the worker on the scaffold.Currently, a drywaller on the ground physically lifts a 100+ pound sheet of drywall, plywood or other heavy materials upwards as much as 20 feet to the person on the scaffold, who then has to lift and/or pull the materials up onto the scaffold. Both people must use their arms, knees, shoulders and back to lift the heavy material, and the worker on the scaffold sometimes uses his foot to slide the material up onto the scaffold. The PB-DSR helps eliminate this unsafe lifting procedure by providing a rolling mechanism to roll the sheet of material instead of lifting it. This takes most of the weight of the heavy material off the workers, making it safer and easier, and possibly reducing arm, shoulder, back and foot injuries from manually lifting the heavy sheet of drywall. It is an inexpensive way for drywall and construction companies to more likely than not reduce the number of workplace injuries and worker's compensation claims. |
