Abstract: An information processing apparatus according to an embodiment includes: a common data model management unit that manages information indicating a common data model corresponding to a plurality of modules in common; a unique data model management unit that manages information indicating a unique data model corresponding to at least one of the modules; and a common management unit that manages a version of a module corresponding to the common data model managed by the common data model management unit, a version of a module corresponding to the unique data model managed by the unique data model management unit, and a version of a module corresponding to a newly installed data model, and verifies compatibility of the versions.

Abstract: Implant inserters and related methods are disclosed herein, e.g., for delivering a fusion cage or other implant to a spinal disc space and for rotating or articulating the implant within the disc space. An exemplary instrument can include a slider that is slidably mounted to a body to define an implant clamp. A locking mechanism can allow the slider to be quickly disassembled from the body and for fast and convenient loading and unloading of an implant to the instrument. An actuation knob can be moved between a first position in which the implant is locked from rotating relative to the instrument and a second position in which the implant is retained to the instrument but allowed to rotate relative to the instrument.

Abstract: A balanced/unbalanced filter module includes a switch including a first port that inputs and outputs unbalanced signals in a first frequency band, a second port that inputs and outputs unbalanced signals in a second frequency band, and a third port that inputs and outputs unbalanced signals in these two frequency bands. The switch switches a signal path. An unbalanced I/O port of a first filter that passes signals in the first frequency band is connected to the port. A port of a second filter that passes signals in the second frequency band is connected to the port. Individual balanced I/O ports of each of the first and second filters are connected to first and second branch ports with substantially the same electrical length. A balance coil for impedance matching is provided between the first and second branch ports.
