摘要： A wall hanging apparatus for a projection apparatus comprises a fixing seat installed at the lower surface of the projection apparatus, supporting arm whose lower end is fixed on the surface of the fixing seat and reflection mirror fixed at the upper end of the supporting arm and corresponded to a projection lens of the projection apparatus. Whereby, the projection apparatus can have both the portability of a prone type projection apparatus and space saving characteristic of a ceiling hanging type projection apparatus and can be used in an indoor space with a lower height to allow the usage of the projection apparatus is diversified. And, a trapezoid deformation of an image caused from the deviation of the angle of incidence can be modified effectively and quickly by adjusting the angle of the reflection mirror.

摘要： An antenna assembly includes a circuit board, and one antenna device disposed on one side of the circuit board, for receiving and transmitting signals laterally, and another antenna device disposed on the other side of the circuit board, for receiving and transmitting signals vertically, to prevent the signal receiving and transmitting operations of the antenna devices from being interfered with each other. The antenna devices each includes two antenna members for receiving and transmitting signals toward different directions relative to each other, and each having two or more antenna segments for receiving and transmitting signals of different frequencies.
