Abstract:
This invention disclosure relates to a community access television (CATV) signal distribution system which improves signal isolation issues for systems which are distributing both CATV signals and in-home entertainment (IHE) signals. The signal distribution system includes a signal input port, a first multi-port signal splitter and a second multi-port signal splitter. The first multi-port signal splitter is coupled to the signal input port through a first diplexer, and the second multi-port signal splitter is coupled to the signal input port through a second diplexer. In some embodiments the first diplexer high-pass node and the second diplexer high-pass node are coupled together. In some embodiment the signal distribution system includes a signal output port coupled to the signal input port through a third diplexer. The high-pass node of the third diplexer is coupled to the high-pass node of the first diplexer.
Abstract:
A downstream bandwidth output level tilt compensation device that can be inserted into a signal transmission line of a CATV system on a premise of a user. The device includes first and second filters to output first and second band signals, respectively. Detectors output a measurement representative of a characteristic (e.g., RF power) in the first and second band signals, respectively. A comparator uses the measurements from the detectors to determine a correction signal. A variable slope adjusting circuit is provided to adjust the gain slope of the downstream bandwidth responsive to the correction signal. The device includes a third filter after the variable slope adjusting circuit to pass a third band signals corresponding to the first and second signals. A second comparator uses measurements from the third signal to adjust the connection signal.
Abstract:
A maintenance method and system is provided. The method includes providing a device comprising a thru state switch and condition circuits. The device is permanently connected between a feed system and an antenna. The device receives a first control signal and disables a connection between the analyzer and the antenna. The device receives additional control signals and enables conditions. The device generates altered responses of the feed system. The altered responses are associated with the conditions. The altered responses are used to normalize an analyzer and the feed system or troubleshoot a communication system.
Abstract:
A surge protection device with an internal circuitry that protects a premise device from a surge input that arises from a transient event, e.g., a lightning strike. The internal circuitry can comprise a surge path that includes windings, e.g., inductors, and in one embodiment the surge path comprises a first winding and a second winding that is coupled in series to the first winding. The internal circuitry can also comprise a blocking element that is positioned relative to the surge path so that the blocking element receives the surge input before the premise device, wherein the blocking element can be selected so as to isolate the premise device from the surge input.

Abstract:
A circuit for automatically terminating a user port in a coaxial cable system includes a signal path extending from a user-side port toward a supplier-side port, the signal path including a conductor and a ground. The user-side port is adapted to connect to a user device. The circuit further includes a passive signal sampler coupled to the signal path, and a comparator element in communication with the passive signal sampler. The comparator is adapted to compare a line signal on the signal path to a reference signal and generate an output. A switch disposed in the signal path has a first state for terminating the line signal and a second state for passing the line signal. The first state and the second state are responsive to the output generated from the comparator.
Abstract:
There is provided a terminate or permit device that includes an internal circuitry, which discriminates between noise and non-noise transmissions. In one embodiment, the internal circuitry comprises a switch and termination unit ("STU") with a signal path that is used to terminate and/or permit the upstream bandwidth based on the presence of non-noise transmissions. The internal circuitry also comprises a signal processing unit ("SPU") with a processing circuit, which is configured to identify the non-noise transmissions from the upstream bandwidth, and to cause the STU to permit the upstream bandwidth based on the presence of the non-noise transmissions.

Abstract:
In order to fabricate a hollow part (29, 30), according to the method disclosed, fibres impregnated with resin are draped around a core comprising, inside an inflattable elastomer bladder (18), an internal rigid portion (13) which melts at a temperature lower than the polymerization temperature of the resin. The thus drapped core is introduced in a twin part mold (22, 28), and the assembly is heated to a moderate temperature. The molten material of the core is extracted through a conduit (12), and an air inlet is provided inside said core through another conduit (9). The internal volume of the bladder (18) is pressurized by means of the conduit (9), and the assembly is heated to the polymerization temperature. After cooling, the hollow part (29, 30) is removed from the mold (22, 28), and the bladder (18) is extracted through an orifice provided in the hollow part. The method allows to fabricate hollow bodies such as tanks, structural elements or drums.
