The present disclosure describes a device and methods for safely and accurately placing screws into bones with a powered driving device. By employing multiple layers of fail-safe features and image-guidance systems, the powered driving device provides safe, accurate, and efficient screw placement. That is, the powered driving device may continuously monitor a screw advancement and placement and may automatically shutdown when improper placement is detected. Monitoring placement may be conducted by a microcurrent-monitoring system, by an image-guidance system, or by any other appropriate sensory system. Additionally, upon detecting that screw insertion is complete, the powered driving device may be automatically shutdown. As screw placement is continuously simulated by image-guidance in real time, multiple redundant verification steps are eliminated, providing highly accurate screw placement while decreasing clinician error, device contamination, and surgical time, the decreased surgical time associated with decreased patient-recovery time and associated medical costs.

A system and method for the temporary closure of a wound, especially an abdominal wound, to facilitate re-entry, final closure, and long term healing of the wound. An abdominal wound dressing and methods of use are described that enable the application of negative pressure to the wound site in a site healing promoting manner while also limiting the formation of adhesions that would prevent the removal of the dressing.

This invention relates to active protective garments which are inconspicuously worn by an individual and which activate upon certain conditions being met. Activation causes inflation of regions of the active protective garment to provide padding and impact cushioning for the wearer. The invention is an active protective garment such as pair of shorts or pants, a jacket, a vest, underwear, and the like. The garments comprise multiple layers of material that constrain pockets or regions that are inflatable by a source of compressed gas or foam. The garments also comprise sensors to detect ballistic parameters such as acceleration, distance, relative acceleration, and rotation. The sensor information is used to determine whether activation is required. Detection and activation are accomplished in a very short time period in order to offer maximal protection for the individual wearing the garment. The system comprises a computer or logic controller that monitors the sensor data in real time and coordinates the information from all sensors. The system calculates velocity, distance, and rotational velocity. A rule-based system is used to detect a complex fall in progress and discriminate said fall in progress from the events of every day life. The pockets or inflatable regions of the garment protect the individual against falls and other impacts that may cause bone fracture or organ damage.

The packing manager provides an automated method that allows existing AV scanning technology to be applied to detect known malware samples packed by one or more packers that are potentially proprietary. The packing manager tracks the memory areas to which an executable binary writes and executes, and so can unpack programs packed by multiple arbitrary packers without requiring reverse-engineering of the packers or any human intervention. By tracking page modification and execution of an executable binary at run time, the packing control module can detect the instant at which the program's control is first transferred to a page whose content is dynamically generated, so AV scanning can then be invoked. Thus, code cannot be executed under the packing control manager without being scanned by an AV scanner first.
