An example game device automatically receives character data from another game device positioned nearby through wireless communication, and generates an other-player character based on the character data. For example, imaging can use optical phase modulators based on optical delay lines that, in conjunction with a swept-source laser, can be used to achieve heterodyne swept source optical coherence tomography. The control circuit may also include a failsafe circuit that has at least one input that can be connected to a control device and at least one output that can be connected to the relay. The tongue is designed to engage the latch mechanism of a sterilization container when the container is in the closed position and the latch mechanism is in a latched position.
