A system and method for the preventing unintended surgical instruments and surgical disposables from remaining in the body cavity of a patient post surgically. Individual items are tagged with an RFID transponder tag preferably at the time of manufacture. Then, after an operation is complete, but prior to would closure, the body of the patient is scanned using an RFID reader device, such as, a hand held reader device to detect the presence of any latent RFID tags. As long as no tags are identified it is presumed that the body cavity is free of any unintended items. This avoids sponge counting and other overhead intensive methods of accounting for surgical items during a surgical procedure.

A computer system includes a security subsystem which is able to trustfully track which files or storage areas of a storage device have been altered since a last virus scan. The trusted information can then be used to accelerate scans for undesirable code or data such as viruses and invalid or corrupt registry entries. In the case of viruses, files or storage areas which have been altered are scanned against a super-set of virus definitions. Unaltered files or storage areas are scanned against a subset of virus definitions.

Provided herein is a retraction device for retracting soft tissue from the dental surfaces in the oral cavity of a patient. The retraction device is comprised of a topology conformable structure, where the topology conformable structure is adaptable to be delivered to the oral cavity in a constrained shape. The device can then undergo a conformation change in the oral cavity, where the device transforms into its unconstrained shape. The unconstrained shape of the device creates a useable working field in the oral cavity. The useable working field can provide increased accessibility to and/or visibility within the oral cavity. Also provided herein are methods for using the device and kits.

A medical supply such as an operating room towel, laparotomy sponge, gauze pad, bandage, or swab with radio frequency detectable material which eliminates the need for re-entry into a patent after operating in situations where medical supplies are missing. The patent can be easily scanned with a handheld scanner to determine if the medical supply was accidentally left inside the patient. If no RF detectable material is observed, unnecessary re-entry into the patient is prevented. The radio frequency detectable material is incorporated into the medical supply as a tag, in the handle, as a handle, stitched to the medical supply, woven into the medical supply, or sewn into a seam in the medical supply. An identifier on the medical supply indicates that the medical supply is an RF detectable medical supply. In addition to preventing unnecessary re-entry, scanning for RF detectable material is much safer than scanning for x-ray detectable material.

A networked configuration of structural health monitoring elements. Monitoring elements such as sensors and actuators are configured as a network, with groups of monitoring elements each controlled by a local controller, or cluster controller. A data bus interconnects each cluster controller with a router, forming a networked group of “monitoring clusters” connected to a router. In some embodiments, the router identifies particular clusters, and sends commands to the appropriate cluster controllers, instructing them to carry out the appropriate monitoring operations. In turn, the cluster controllers identify certain ones of their monitoring elements, and direct them to monitor the structure as necessary. Data returned from the monitoring elements is sent to the cluster controllers, which then pass the information to the router. Other embodiments employ multiple sensor groups directly connected to a central controller, perhaps with distributed local control elements. Methods of operation are also disclosed.
