    摘要: An antenna assembly has a lower break assembly and an upper break assembly. Both have a center fed transmission line within a conductive tube, and both are mutually connectable for connecting the transmission lines to each other at a junction. When connected, the lower break assembly and upper break assembly form one pole of a center-fed dipole radiator without significant signal loss through the junction.

    摘要: A multiplexer circuit adapted to receive signals comprises two filter circuits. The first filter circuit presents a high impedance to signals outside a first frequency range and the second circuit presents a high impedance to signals outside a second frequency range. Isolation matching circuits enable transmission and reception of one of the signals in the first or second frequency ranges without degradation or interference with the other range. An embodiment allows transmission and reception of satellite Orbcomm frequencies over a standard AM/FM antenna without effect on the AM/FM signal.

    摘要: An AM/FM/CB/cellular telephone antenna includes a first frequency self-resonant circuit at a position above the lower end of the antenna such that the electrical length of the lower section of the antenna is equivalent to one-quarter wavelength for a frequency in the FM frequency range and a second frequency self-resonant circuit disposed below the first frequency self-resonant circuit. The first self-resonant circuit presents a high impedance in the FM frequency band and the second self-resonant circuit presents a high impedance in the cellular frequency range. The entire length of the antenna is equivalent to one-quarter wavelength in a frequency in the CB frequency band. The antenna wire is wound around a fiberglass core, and the FM self-resonant circuit is formed by a tightly wound, coiled section of the wire together with a thin-walled brass tube extending over the core in the area of the tightly wound section. A thin dielectric film is applied between the tube and the tightly wound section of antenna wire thereby forming a capacitor. There is no direct electrical connection between the antenna wire and the tube, and the capacitance between these elements is essentially only stray capacitance. Two antennas, each comprising two frequency self-resonant circuits, are connected by means of a multiplexing circuit to AM/FM, CB and cellular telephone apparatus.

    摘要: In a telecommunication switching system, an apparatus for automatically converting ISDN codeset and codepoint protocol in messages transmitted to the telecommunication switching system from a plurality of other telecommunication switching systems each using a diffrent ISDN codeset and codepoint protcol than the telecommunication switching system to identify the same data information. All telecommunication switching systems are interconnected by data channels. Further, the apparatus is responsive to another ISDN message generated by the telecommunications switching system for transmission to another one of the plurality of telecommunication switching systems to convert the codeset and codepoint protocol of the other message to the codepoint and codeset protocol of the other one of the plurality of telecommunication switching systems. The conversions are performed by using sets of conversion tables each identified with an ISDN data channel, and the identity of the data channel is used to select which set of tables is to be used to convert a codeset and codepoint protocol.
