| 20080263276 | METHOD AND APPARATUS FOR EVALUATING AND IMPROVING DISK ACCESS TIME IN A RAID SYSTEM - Techniques for improving access time in data storage systems are disclosed. These techniques can be used to prevent undesirable access delays that are often experienced in conventional storage systems. “Slow-access” can be defined as an access operation that does not successfully complete within a predetermined amount of time. The “slow-access” time can, for example, be defined based on a system requirement, specification, or a particular need of a specific application. As such, when detected “slow-access” indicates a potential performance problem that can manifest in undesirable effects. A data storage system is evaluated for potential performance problems by scanning it for “slow-access.” In addition, preventative measures are taken to prevent occurrence of a “slow-access” once it has been identified. These measures can prevent the undesirable effects experienced in conventional storage systems. This also means that specific system or application requirements can be certified and met. | 10-23-2008 |

| 20080223679 | Transport trolley - A luggage trolley comprises a dragging bracket, a retractable drawbar, and at least a wheel set on the bottom of the dragging bracket. On the dragging bracket there is a wheel-moving assembly that can be opened to the forward dragging direction and form a supporting point. The luggage trolley can be very smooth and stable when dragged because it can form a stable structure having three supporting points including the two wheels and a newly-added wheel of the moving wheel-assembly. The newly-added wheel is the pivot which bears the most weight of the luggage when the luggage inclines. It becomes the bearing support and greatly improves the mobility of the trolley when dragged and the stability of the trolley when standing. | 09-18-2008 |
