Abstract: The present invention relates to a method of purchasing goods via transnational shipping and its computer program product which assists users to evaluate the required vehicles (means of transportation), required time, and expenses during the shipping process of goods, and after confirmation of the route and the purchase, directly makes reservation for each vehicle. In this way, the user can see the required time and expenses for the shipping, and choose the most suitable route according to his/her own needs. Moreover, reservation is made automatically for each vehicle service provider. As a result, the complicated procedures for placing orders on translational goods are simplified for the user.

Abstract: The present invention provides a surveillance camera with rotary camera lens comprising a body having a pair of opposed and spaced pivot supports with a receiving space formed therebetween, a pivotable lens seat having two ends and a pivot portion at each of these two ends, and a pivot assembly connected between one of the pair of pivot supports of the body and the pivot portion of the pivotable lens seat so that the pivotable lens seat may be pivotably connected to the body within the receiving space and stopped at any desired pivoting position.

Abstract: The present invention provides a wireless video/audio transmission device for bi-directional communications, which comprises an emitting device and a receiving device. The emitting device comprises a 2.4 GHz or 5.7 GHz emitting module and a UHF receiving module. The receiving device comprises a 2.4 GHz or 5.7 GHz receiving module and a UHF emitting module. Video, audio, and a digital control instruction are emitted out by the emitting module after signal processing and transmitted to the receiving module. The receiving module is used to demodulate and convert the signal into a video, an audio, and an output control instruction. A control instruction and an analog audio signal are mixed and modulated by the UHF emitting module and emitted out to the UHF receiving module, thereby demodulating and converting the signal into an audio signal and an output instruction.

Abstract: This invention is to provide an angle adjusting mechanism for an antenna to be used to connect between an antenna and its casing. The angle adjusting mechanism includes a casing provided with a pivoting recess, an antenna provided with a connecting sleeve, and a linking member which has a hollow body and a first, second and third pivoting sleeves formed in T-shape. The first pivoting sleeve is pivotably connected to the connecting sleeve of the antenna; the second and third pivoting sleeves are pivotably connected to the pivoting portion of the casing. The characteristics of this is that each of the first, second, and third pivoting sleeves of the linking member is provided with a slotted or split free end and a resilient tab through which to achieve an resilient design.
