Button anchor system for moving tissue

A system of non-reactive components for moving or for moving and stretching plastic tissue that exerts a relatively constant dynamic force over a variety of distances and geometries, that is easily adjustable, and is self-adjusting. This system includes a “button anchor system” for moving tissue, particularly including deep fascia and muscle layers of the abdominal or thoracic cavity wall, in surgical, post surgical, and post traumatic reconstruction where the wound margins are beyond a distance that permits normal re-approximation. Button anchor assemblies allow re-approximation of severely retracted abdominal wall and full thickness thoracic wounds where a closure force is required to be applied to the sub-dermal layers. Systems of this invention allow for such a force to be applied and externally controlled during treatment.

InactiveUS20060037685A1Safe of air pressureSafely ventingWithout separate inflatable insertsRimsEngineeringProjectile
A multi-piece safety wheel includes a plurality of circumferentially spaced, interlocking bosses and tabs on the inner rim portion and outer rim portion. In the event of improper disassembly of the wheel with an inflated tire mounted thereon, any failure of the wheel assembly fasteners will result in the outer rim portion separating from the inner rim portion a sufficient distance to vent air pressure from within the tire, at which point the interlocking bosses and tabs resist further movement of the outer rim portion. The outer rim portion is thereby resisted from becoming a potentially dangerous projectile. A method of safely deflating the tire upon improper disassembly of the multi-piece safety wheel is also provided.

Abnormal system service call detection method and system

The invention relates to an abnormal system service call detection method and system. The abnormal system service call detection method and system are mainly used for monitoring the phenomenon that an operator handles services illegally and storing operator information, service information and time in a log output mode to for manual inspection. When the operator handles the services illegally, because scripts similar to plug-in scripts are used for assisting a user in service handling, access rate is higher than that of manual handling. Because layer monitoring is added to a public page, loading time is accordingly recorded by a web server when the handing interface of each service is loaded, and loading time is recorded through a queue every time. The length of the queue is a fixed value, and when the number of time recorded in the queue reaches the fixed value, front time and tail time are compared. If the time difference is smaller than a threshold value, the operator information, the service information and the time are recorded in a log mode and session information of the operator is cleared to stop the operator from continuing handing services. In order to flexibly set the length of the queue and threshold values and guarantee system pressure, the queue length and the threshold values are recorded in a configuration file mode.
