A honeypot system for protecting a mobile communication network against malware includes one or more user-less mobile devices including a monitoring module for monitoring the events conveying software applications in the associated mobile device as well as a controller client module that emulates human-like interaction with the user-less devices as a function of the events monitored. The system controllably performs, for the applications conveyed by the events monitored, one or more of the following steps: i) installing the application on the device; ii) executing the application installed on the device; and iii) de-installing the application from the- device. After any of these steps, the state of the device is checked in order to detect if any anomalous variation has occurred in the state of the device indicative of the device being exposed to the risk of malware. If any anomalous variation is detected, the system issues a malware alert message.

A scanning apparatus and method for generating computer models of three-dimensional objects comprising means for scanning the object to capture data from a plurality of points on the surface of the object so that the scanning means may capture data from two or more points simultaneously, sensing the position of the scanning means, generating intermediate data structures from the data, combining intermediate data structures to provide the model; display, and manually operating the scanning apparatus. The signal generated is structured light in the form of a stripe or an area from illumination sources such as a laser diode or bulbs which enable data for the position and color of the surface to be determined.

A method, system, and computer program product for detecting malware from outside the host operating system using a disk, virtual machine, or combination of the two. The method, system, and computer program product detects malware at the disk level while computer files in the host operating system are in actual program execution by identifying characteristic malware properties and behaviors associated with the disk requests made. The malware properties and behaviors are identified by using rules that can reliably detect file-infecting viruses. The method, system, and computer program product also uses the disk processor to provide accelerated scanning of virus signatures, which substantially decreases overhead incurred on the host operating system by existing malware detection techniques. In the event that malware is detected, the method, system, and computer program product can respond by limiting the negative effects caused by the malware and help the system recover to its normal state.

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.

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.
