  • Patent number: 10799282
    Abstract: An electrosurgical system includes an electrosurgical instrument coupled to an electrosurgical generator. The electrosurgical system may include a first sensor and a second sensor, which are configured to detect redundant tissue properties and output a signal corresponding thereto. The electrosurgical system has a signal processing circuit for receiving and modifying the output signal from the second sensor. The electrosurgical generator may include a controller for receiving an output signal from the first sensor and a processed signal from the signal processing circuit. The controller compares the two signals received and shuts down the system based on the comparison of the first sensor and a processed signal.

  • Publication number: 20120179159
    Abstract: An interlock system and related method includes a battery assembly, and first and second modules. The battery assembly has first and second power contacts, and a sense contact. The battery assembly includes one or more cells, a standby circuit, and an interface circuit. The standby circuit electrically couples to the first power contact and the sense contact for generating a standby signal in the absence of a detected external electrical coupling between the first power contact and the sense contact. The interface circuit electrically couples to the second power contact and to the at least one cell. The interface circuit is adapted to electrically decouple the second power contact from the at least one cell as a function of the standby signal. The first module is attachable to the battery assembly and has a first pair of contacts adapted to couple with the first power contact and the sense contact of the battery assembly.
