A cap is coupled to the central coupling member of the suction cup with a stem for actuating the suction cup.

Abstract: An antenna device includes an antenna member having a plate, a conductor member disposed on one side of the plate, and another conductor member disposed on the other side of the plate, the plate includes one or more orifices and one or more apertures, and a coupler includes one or more positive electrodes and one or more negative electrodes engaged through the orifices and the apertures of the antenna member and electrically coupled to the conductor members respectively. A housing includes a chamber for receiving the plate of the antenna member, and a cylindrical member having a bore for receiving the coupler. The housing includes two housing members having a chamber for receiving the plate.

Abstract: An antenna device includes a coupler rotatably attaching to a support device, a connector rotatably attached to the coupler with a pivot axle and having an extension, and having a stop. An antenna member includes a bore formed in one end for rotatably receiving the extension of the connector. The antenna member includes a stop for engaging with the stop of the connector, and for limiting the antenna member to rotate relative to the connector. The connector includes one or more projections extended into a peripheral groove, and the antenna member includes one or more anchoring members for engaging with the projection of the connector, to position the antenna member to the connector at selected angular position.

Abstract: An attaching device for attaching an antenna member to a coupling member of an electric facility includes a housing having a projection extended from one end for coupling to the antenna member, and another end for attaching to the electric facility, a casing is engaged into the housing and includes one end secured to the housing, and the other end for attaching to the coupling member of the electric facility, and a coupler is received in the casing and includes a conductive member engaged in a receptacle for electrically coupling to the coupling member of the electric facility and the antenna member, and for allowing the antenna member to be easily coupled to the coupling member of the electric facility.

Abstract: A ceiling antenna housing includes a lower receptacle having a number of orifices, an upper receptacle disposed on the lower receptacle and having a number of cavities aligned with the orifices of the lower receptacle, an antenna member received between the lower receptacle and the upper receptacle, one or more anchoring members disposed on the upper receptacle and each having a hooking member, and a number of fasteners for securing the receptacles and the anchoring member together. The hooking members of the anchoring members may be used for engaging with hanger members typically for attaching ceiling panels to the ceiling, to attach the ceiling antenna housing to the ceiling.

Abstract: An antenna device includes a coupler rotatably attaching to a support device, a connector rotatably attached to the coupler with a pivot axle and having an aperture formed in a free end, and having a stop. An antenna member includes an extension extended from one end for rotatably engaging into the aperture of the connector. The antenna member includes a stop for engaging with the stop of the connector, and for limiting the antenna member to rotate relative to the connector. The connector includes a number of grooves, for engaging with a projection of the antenna member, to position the antenna member to the connector at selected or predetermined angular position.

Abstract: Disclosed is a high-frequency wireless signal coupler, in which a plurality of metallic signal lines on two opposite sides of an electronic device is invested with a Teflon body, respectively. The metallic signal lines transmit a high-frequency signal through an impedance of 50 or 75 ohms at a frequency as high as 60 GHz. The coupler is also provided with an outer frame for encaging the Teflon body such that two sides of the electronic device can be securely connected to form the electronic device a unitary body.

Abstract: A ceiling antenna housing includes a receptacle having a chamber to receive an antenna member and having a number of orifices for receiving fasteners. The fasteners each includes an aperture for engaging with hanger members typically for attaching ceiling panels to a ceiling, and for allowing the ceiling antenna housing to be easily and readily attached to the ceiling without drilling holes by the users themselves. A cover is attached to the receptacle and has a number of cavities for receiving the fasteners. The cover may also include a hooking member or an anchoring member to engage with the hanger members.

Abstract: A signal connector is provided according to the invention which signal connector relates to a signal connector used to connect to an electronic circuit and can be switchedly operated between two signal sources. The elements needed are simplified so that the signal connector can reduce the prime cost.

Abstract: A lighted antenna is provided. The lighted antenna is composed of an antenna pole, a base block, a cylindrical body, a control circuit, and a battery. The base block has a hole in the center for fixing the antenna in upright position, and a plurality of clipping holes surrounding center hole. The cylindrical body has a plurality of cylinder clips formed along the circular rim on one end, corresponding to the positions of the clipping holes. A plurality of light-emitting diodes are installed inside the base block and positioned directly below respective clipping holes. The cylindrical body is attached onto the base block by press fitting the cylinder clips into respective clipping holes. Whenever the antenna is activated, light is projected onto the antenna surface with inclined angle, passing through unblocked portion of clipping holes, to produce flashing light.
