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: One of the plurality of first slave receiving apparatuses which serves as a reference first slave receiving apparatus repeatedly transmits a wireless control signal for controlling synchronization between a first receiving apparatus segment and a second receiving apparatus segment. One of the plurality of second slave receiving apparatuses which serves as a reference second slave receiving apparatus transmits a reference timing signal for performing synchronization in the second receiving apparatus segment including the reference second slave receiving apparatus to the second master receiving apparatus in synchronization with the wireless control signal.

Abstract: A mobile device is disclosed. A battery housing cover mechanism (80) of the mobile device comprises a cover member (81), a pivot shaft module (90) having a pivot shaft (92), and a pivot shaft module support mechanism (I00). The module (90) is movably supported by the module support mechanism (I00). The pivot shaft (92) is located in the recessed section (107). When the cover member (81) is opened excessively beyond the normal open position, the module (90) is moved to pull the pivot shaft (92) out of a recessed section (107). Therefore, the pivot shaft (92) is prevented from receiving an excessive force.

Abstract: A work item displaying system includes a database (6) storing a plurality of work item information lists (66) recording relevant information on work items, a web server (4), a number of browsers (8), and an application server (2). The application server includes: an expected completion ratio calculating module (261) for calculating an expected completion ratio as at a current time for each work item; a priority index calculating module (262) for calculating a priority index for each work item; a sequencing module (27) for prioritizing the work items according to their priority indexes; and a displaying module (28) for displaying the prioritized work items. A related work item displaying method is also disclosed.
