摘要： The present invention relates to an antenna arrangement on a circuit board (10) extending along a length direction, L, and a width direction, W, the width direction being orthogonal to the length direction. The antenna arrangement comprising: a cell-band antenna (20); a ground plane (30) associated with the cell-band antenna; and a slit antenna (40) arranged in a slit antenna portion (32) of the ground plane, the slit antenna comprising a slit (42) in the ground plane, the slit having in the width direction a slit extension extending from an in the length direction extending edge (34) of the ground plane, the slit extension being 50-95% of an in the width direction extending total width of the slit atenna portion.

摘要： When a floating battery feed circuit is used to power telephone lines, it is desirable to provide an anti-corrosion biasing circuit to keep the voltage on the tip and ring conductors from becoming positive. This can be done using an anit-corrosion circuit that sinks a dynamic amount of current from the tip conductor. A line circuit including such biasing is, however, incompatible with special lines such as PBX lines that rely on a grounded tip conductor in the talk state. In accordance with the present invention, a constant current is supplied from a ground reference circuit to the ring conductor of such special lines only when loop current is flowing. The magnitude of this supplied current is such that the anti-corrosion circuit holds the tip conductor sufficiently close to ground potential to allow the proper operation of circuits connected to the special lines.

摘要： A resistor network is connected to a two wire line and used to detect and overcome changes of direct current levels without disturbing any alternating current signals superimposed thereon. Direct connections between the d.c. source and the network eliminate the effects of any fluctuations in the source voltage. The invention has general utility wherever changes in d.c. levels must be detected; however, a particular use of the invention is to compensate for longitudinal voltages induced on a telephone line.

摘要： A pair of magnetic amplifiers have their input windings serially connected to the receiving end of a transmission line for distinguishing between four different levels of direct current transmitted across that line, each amplifier also having an excitation winding energized by a pulse train and a biasing winding normally maintaining the amplifier core in saturation to minimize the magnetic coupling between the excitation winding and an output winding working through a transistor into an associated relay. The pulse amplitude and the winding turns are so chosen that both cores remain saturated with input currents below a first threshold whereby the two relays are unoperated, between the first and a second threshold, the first core is desaturated to energize one relay; between the second and a third threshold, both cores are desaturated with energization of both relays; and above the third but below a fourth threshold the first core is saturated with opposite polarity while the second core remains saturated to maintain only the other relay energized.
