Surgical implement detector utilizing a radio-frequency identification marker
InactiveUS7307530B2Control moreSevere possibilitySurgeryElectric/electromagnetic visible signallingModulation functionEngineering
A radio-frequency surgical implement detection system detects surgical implements in a surgical wound during and at the completion of a surgical procedure. Surgical implements, including surgical sponges or laparotomy pads, gauze pads and metallic surgical instruments, are individually attached to a non battery-powered, encapsulated radio-frequency marker. The marker comprises an integrated chip having a burnt-in memory code, which is broadcast through an antenna using a modulated carrier frequency. The code is received by an interrogating antenna of a detector. The interrogating antenna provides a power pulse, which is received by the antenna of the radio-frequency marker. The power pulse charges a capacitor, which proves power for the read function, carrier frequency modulation function and broadcast function of the integrated chip, permitting each marker-containing implement to be specifically identified.

Hardened extended firmware interface framework
A method of system for hardening a firmware environment. A trusted core framework of firmware components are segregated from initially non-trustworthy extended firmware components such that the trusted core components are executed in a privileged processor mode, while the extended firmware components are executed in a non-privileged processor mode. An authentication of each extended firmware component is made to determine whether it is secure or non-secure. Through a memory code fault mechanism, memory accesses made by the extended firmware components are trapped, and a determination is made to whether the memory accesses should be allowed based on whether the extended firmware component is secure or non-secure and whether the requested memory page was allocated by the trusted core or a secure extended firmware component. This segregation scheme prevents non-trusted firmware from accessing privileged memory, thereby preventing rogue, errant, or malicious firmware from damaging the trusted core framework.
