A bus converter is disclosed that converts a signal of a synchronous bus into a signal of an asynchronous bus. The container is configured to receive the lid in a first configuration for shipping, and in a second configuration for funereal purposes. The first device then uses the plurality of beamforming feedback packets to select a group of multiple communication devices from among the plurality of second communication devices, wherein the group is selected for simultaneous transmissions to the first communication device. A bit counter performs updown counting operation in response to a count control signal after setting the fuse signals to initial values in response to a set signal and generates counter output signals which are higher or lower than the initial values by a counting number.
