Abstract: A guard for use with a surgical cutting system. The guard includes a housing and wiring. The housing defines a longitudinal passageway, and is configured for releasable attachment to an instrument handpiece. The wiring is coupled to the housing and includes an electrically conductive wire and an insulative material. The wire defines opposing, first and second ends, with the first end being positioned within the passageway. The insulative material covers the wire apart from the first end such that the first end of the wire is exposed within the passageway. The first end of the wire establishes an electrical connection with a cutting tool shank upon placement within the passageway.

Abstract: Methods, apparatuses and systems are described for monitoring physiological parameters by using one or more sensors at a person. First and second physiological parameters of the person are monitored. A determination may be made, at the one or more sensors, that at least one of the first and second physiological parameters has crossed a threshold. An alert event may be generated at the one or more sensors, based on the crossed thresholds. The alert event may then be transmitted to a computing device that is separate from the one or more sensors.

Abstract: A dual clutch transmission is provided with first and second coaxial input shafts, at least one mainshaft, and an output shaft that are coaxial with one another. The transmission has a countershaft offset from the first input shaft that supports seven countershaft gear elements drivably connected to respective gear elements on the first and second input shafts and the at least one mainshaft thereby forming seven forward gear meshes for the transmission. The seven forward gear meshes provide at least nine forward gear ratios for the transmission. The transmission is powershiftable between consecutive gear ratios of the at least nine gear ratios such that no torque interrupt occurs during sequential shifts.

Abstract: In various arrangements, a nebulizer element of a nebulizer may be energized with a drive signal. A phase offset of the drive signal may be measured. A phase delta may be determined. The phase delta may indicate a difference between a target phase offset and the measured phase offset. The target phase offset may indicate a non-zero target phase difference between the voltage of the drive signal and the current of the drive signal. A frequency of the drive signal may be changed to decrease the phase delta.

Abstract: A bifurcated stent includes a first stent section and a second stent section. The first stent section is balloon expandable, has an unexpanded configuration, an expanded configuration, and a tubular wall defining a secondary opening. The secondary stent section is self-expanding and an end of the secondary stent section is engaged to a portion of the tubular wall of the primary stent section defining the secondary opening. The secondary stent section has an unexpanded configuration with a first length and an expanded configuration with a second length where the first length is less than the second length. The secondary stent section is expanded to the expanded configuration after the primary stent section is expanded to the expanded configuration. The secondary stent section forms a portion of the tubular wall of the primary stent section in the unexpanded configuration.
