Abstract: A power supply detection apparatus including a base, a couple of longitudinal motion mechanisms, a couple of lateral motion mechanisms, a couple of pin bases and a couple of vertical motion mechanisms is provided. Each lateral motion mechanism is movably arranged on the corresponding longitudinal motion mechanism and thereby driven to move horizontally. Each pin base is driven to move horizontally by the corresponding lateral motion mechanism and a probe is arranged on each pin base. The probe and the perpendicular lateral motion mechanism are moved along respective directions perpendicular with each other. Each vertical motion mechanism is arranged on the corresponding pin base for driving the probe to move vertically. The probes can be thereby moved to automatically detect an electric power status of an electronic component on a circuit board of a power supply.

Abstract: A flat-proof rim for a pneumatic tire of a wheel is disclosed. The flat-proof rim includes a circular rim body having an outer periphery. A plurality of spaced linkages are arranged along and movably connected to the outer periphery of the rim body, and each have a hoof adapted to be movable between a radially inner position and a radially outer position relative to the rim body. In addition, there is provided an apparatus for driving the linkages so that the hoofs are moved from the radially inner positions to the radially outer positions when the pneumatic tire is deflated while the wheel is rotated at a high speed.
