Abstract: A modular energy system for use in a surgical environment includes a plurality of functional modules including at least an initial module, a functional module, and a terminal module. Each of the plurality of modules has a module control circuit, and a local data bus. An internal data bus is composed of a serial array of the local data busses of the modules. The local data bus may includes a communication switch, a first switch data path between the communication switch and the module control circuit, a second switch data path in communication with the communication switch, and a third switch data path in communication with the communication switch. The third switch data path of a module N is in communication with a second switch data path of a module N+1. The system further includes a termination unit in communication with the third data path of the terminal module.

Abstract: Mitigating a user interface display function of a modular energy system includes receiving formatted video data at a video data converter circuit, providing differential video signaling data to the display from the video data converter circuit, providing a copy of the differential video signaling data to a processor, and determining that the differential video signaling data is changing over time. Mitigating erroneous outputs from an isolated interface includes receiving a state of a first switch of a first footswitch coupled to a first comparator and a reference voltage coupled to the first comparator, receiving the state of the first switch coupled to the first duplicate comparator and the reference voltage coupled to the first duplicate comparator, comparing the output of the first comparator with the output of the first duplicate comparator, and determining activation or deactivation of a surgical instrument coupled to the controller based on the comparison.

Abstract: A modular surgical system is disclosed. The modular surgical system comprises a header module, a first surgical module, a second surgical module, and a module identification circuit. The second surgical module is arrangeable in a stack configuration with the header module and the first surgical module. The module identification circuit is configured to cause a pre-determined current to be transmitted to the first surgical module through the second surgical module in the stack configuration, detect a first voltage indicative of a first position of the first surgical module in the stack configuration, and detect a second voltage indicative of a second position of the second surgical module in the stack configuration. The second voltage is different than the first voltage.

Abstract: Aspects of the present disclosure are presented for systems and methods for identifying characteristics of a return pad in a monopolar electrosurgical system using contact quality monitoring (CQM) and near field communication (NFC) signals. In some aspects, resistance or impedance materials are sensed that may help identify what kind of return pad is being used, including what is the structure of the pad. In some aspects, NFC signals are used to identify characteristics of the return pad. In some aspects, the grounding or return pad may include two separate materials that form an interconnecting or interwoven mesh and both act as non-active electrodes when both contact the patient. A non-zero impedance may separate conductive lines connecting the two separate materials that may be analyzed to obtain a defining signature about that is linked to structural characteristics about the return pad.

Abstract: A knitted fabric is designed and adapted to fit box springs of varying size. The knitted fabric includes four panels that each includes three layers—a middle layer, a top layer and bottom layer. The knitted fabric is elastic and stretches to fit over the box spring. The four panel construction provides a large opening on the top of the box spring, which allows the knitted fabric to be removed from the box spring without removal of the mattress.
