  • Publication number: 20110308365
    Abstract: A safety device for a machine tool includes a machine, a main controller, a detection unit, a warning system, a drive circuit and a temporary stop device. The detection unit includes a contact sensing element and a non-contact sensing element. After the detection unit is induced and triggered by a charged body, a sensing signal is generated and transmitted to the main controller and interpreted by the main controller to drive the warning system, and the drive circuit transmits an analog signal to a charged body of the temporary stop device to rotate a motor of the machine in a reverse direction for a brake. The present invention provides a double sensing protection device with both contact and non-contact sensing effects to improve the safety of using the machine tool and prevent operators from being injured.

  • Patent number: 8079085
    Abstract: A program installed on a computer system registers and is placed on an installed program list or an uninstall software list. A check of the uninstall software list (USL) is added as a secondary verification mechanism to a behavior monitoring engine. A signature-based malware scan engine may be used. If the scan engine does not flag the file as malware, then the behavior monitoring engine monitors the activities performed by the underlying application. When the behavior monitoring engine flags an activity as potentially suspicious, the USL is checked to determine if the application running the process is on the USL. If so, then the process is treated as legitimate and there is no need to alert the user. Only if both the behavior is flagged as suspicious and the application performing the behavior is not on the USL will the user receive an alert as to the potential malware.

  • Publication number: 20110288273
    Abstract: The invention relates to a simple and high yield process for producing a regenerated silk fibroin which does not need dialysis. Particularly, a process of the invention is characterized in that the silk fibroin is precipitated by applying a shear stress and/or changing the solvent power of the fibroin solution. The process of the invention simplifies the process of producing silk fibroin and greatly shortens the process time to 1 to 2 hours, whereas the conventional dialysis process is complex and needs around 2 to 3 days. In addition to reducing the time needed, the process of the invention can increase productivity of silk fibroin by at least 8%.
