Abstract: A cable arrangement mechanism is provided, which is disposed inside the housing of an electronic device. The cable arrangement mechanism includes a first tube, a second tube, and a plurality of first resilient elements. The first tube includes a first base, a first extension connected to the first base and extending from a first inner surface, and a first extrusion connected to the first base and extending from a first outer surface. The second tube includes a second base, a second extension connected to the second base and extending from a second inner surface, and a second extrusion connected to the second base and extending from a second outer surface. The first resilient elements respectively connect the first extrusion and the second extrusion to the housing, so that the first tube and the second tube are rotatably connected to the housing.

Abstract: A projection apparatus, a power management apparatus, and a method for power management thereof are provided. The projection apparatus has a first power socket corresponding to a first power specification and a second power socket corresponding to a second power specification. The second power specification is different from the first power specification. A voltage detection unit is adapted to detect an input voltage received by a powered power socket, wherein the powered power socket is the first power socket or the second power socket. A control unit decides whether the input voltage detected by the voltage detection unit is matched up with the power specification of the corresponding powered power socket to determine an operation mode of the projection apparatus and to determine whether the projection apparatus provides an alarm message to ensure safety of use.
