Abstract: A vehicle loads at least one of a plurality of upper units having space to store a person or an object on an under unit including a drive mechanism that rotates wheels in the vehicle. The vehicle includes an under unit including a drive mechanism that rotates wheels and the at least one of the plurality of upper units loaded on the under unit. The under unit includes a loading unit, on which the at least one of the plurality of upper units as described above can be loaded. Each of the plurality of upper units includes a joint that joins to a different upper unit that is adjacently loaded.

Abstract: A data bypass system diverts data calls to a central office based modem bank and a data network at the subscriber's discretion. The data call diversion is based on a data service prefix in the user's dialing string. The data bypass device translates a subsequent telephone address of a data service supplier into a data network address. The data bypass system is either analog or digital and has a line card with a switch that selectively connects the subscriber line to the voice switch or to a data switch or router through two respective concentrators. The line card includes a data call prefix detector that controls the switch in response to a data call prefix that precedes a data call telephone number.

Abstract: A digital communication path network includes a first time division switch for producing a first time division multiplexed transmission signal, a cell assembly section for generating a broadcasting cell address, and for forming a cell from the transmission signal and the broadcasting cell address, a cell switch for transferring the cell from the cell assembly means to a plurality of output ports in accordance with the broadcasting cell address, a plurality of cell disassembly units respectively connected to the plurality of output ports, each for disassembling the cell, a plurality of second time division switches respectively connected to the plurality of cell disassembly units, each for producing a second time division multiplexed transmission signal from the disassembled cell in response to a time slot control instruction and a control section for selectively issuing the time slot control instruction to each of the plurality of second time division switches based on a communication path connection informat
