Abstract: A CATV/MoCA signal distribution system includes a first 2-way hybrid splitter for receiving a CATV input signal and splitting it into first and second CATV output signals, a second 2-way hybrid splitter for receiving the second CATV output signal and splitting it into third and fourth CATV output signals, with the latter being connected to a CATV output port. A first diplex filter is receptive of the first CATV output signal, and MoCA signals for providing electrical isolation therebetween and connecting them to a modem port. A second diplex filter is receptive of the third CATV output signal and MoCA signals for providing electrical isolation therebetween and connecting them to a Gateway port. A resistive splitter is connected between the first and second diplex filters and a plurality of individual MoCA signal ports for providing bidirectional MoCA signal flow therebetween.

Abstract: In a grounded electrically conductive housing for an electrical device, common electrically conductive connection points for one or more components connected thereto to be protected from harmful voltage surges, are provided with a spark gap formed between the connection points and ground, via either electrically conductive surge rods, electrode chips, or eyelets for conducting the voltage surges across the spark gap to ground thereby protecting the associated components from damage due to a voltage surge.

Abstract: Apparatus and methods for controlled splitting and isolation of signals in a radio frequency network. In one embodiment, the network comprises a cable television network, and the apparatus comprises a signal splitter having controlled isolation loss at its output ports in at least one frequency band, thereby enabling communications between terminal devices at the subscriber premises that would otherwise be isolated by high losses typical of prior art splitters. The splitter apparatus can also be utilized with a filter/reflector circuit that advantageously provides maximal downstream frequency spectrum bandwidth while suitably reflecting the aforementioned communications to maintain them within the subscriber-side network without interference.

Abstract: Apparatus and methods for the management of radio frequency spectrum within a network such as a CATV network. In one aspect of the invention, an improved signal reflector apparatus adapted for use in the network is disclosed, the reflector circuit being designed to strongly reflect signal frequencies at the lower end of the CATV reverse band, and/or above the higher end of the forward band, while simultaneously allowing the rest of the reverse band and the entire forward band to pass freely through the device. This selective filtering of the spectrum allows control signals generated within a premises or private network to be directed (by reflection) to other devices within that network. A blocking element (e.g., amplifier) may also be used to provide control of the transmission and attenuation profile of the reflector apparatus. The passage of power signals such as DC or low frequency AC is also optionally provided.

Abstract: A conducting housing (to be closed by a lid) for a coaxial cable distribution network has a common port and one of an aerial or pedestal port. A motherboard carries an RF circuit and a transfer switch. In one setting of the transfer switch the RF circuit connects a coaxial pin at the common port with a coaxial pin at the pedestal port. In the other setting the common port pin is connected to the aerial port pin. When the aerial port is used on a rectangular housing, a transmission line forms part of the RF circuit between the motherboard and the aerial port. The transmission is preferably a central conductor spaced over most of its length by air from an outer conductor in the form of an inverted U enclosing the central conductor on three sides. Preferably a ground plane on the back of the motherboard connects to the transmission line outer conductor to provide a path entry in the housing at both ends for ground currents generated by signals in the RF path.

Abstract: A conducting housing for use in a coaxial cable distribution system is of larger length than width and defines an RF signal path therein. A part of the RF signal path is the inner conductor of inner and outer approximately co-extensive conductors. The inner conductor except near its ends has only air separating it from the outer conductor. The outer conductor will usually be of a U-shape lying, in section, on three sides of the central conductor. The outer conductor may be structually combined with an insulating plate supporting the remainder of the RF circuit.
