Abstract: An upstream bandwidth conditioning premise device for use as part of a CATV system and for placement on or near a user's premise to reduce noise created on the user's premise that would otherwise be injected into upstream transmission channels and passed into an RF main signal distribution system of the CATV system. The device includes a variable attenuation device, a signal measurement circuit, a memory circuit and an electronic circuit, which is configured to iteratively determine (i) whether an incremental amount of additional attenuation is to be applied and (ii) whether at least a portion of a previously applied incremental amount of attenuation is to be removed. The electronic circuit includes a counting circuit, a threshold comparison circuit configured to compare a peak signal strength to a predetermined threshold, and a peak comparison circuit configured to compare a contemporary peak signal strength to a previous peak signal strength.

Abstract: An integrated filter connector apparatus that performs the functions of a coaxial cable connector component combined with the functions of an in-line signal conditioning component. The apparatus eliminates at least one exposed point of connection between a separate coaxial cable connector component and an in-line signal conditioning component. Elimination of such a point of connection likely reduces RF ingress into a signal path and likely reduces interference with a signal traveling through the signal path. Embodiments of the connector apparatus provide various types of connector interfaces.

Abstract: A fixed filter assembly kit includes a plurality of filters with associated terminals inside a case. A booklet disclosing which filters are associated with which terminals as well as technical information about each filter is includes inside the lid. When the case lid is opened, the terminals are available to a user to perform proof of performance testing on a CATV system.

Abstract: An integrated seal assembly is provided, as is a coaxial cable system component incorporating the seal assembly with a connector for coupling to an externally threaded port. The seal assembly includes a bellows-type seal formed at least partially of a conductive elastomer and having an elastically deformable tubular body and a plurality of sealing surfaces, and an integral joint-section intermediate an anterior end and a posterior end that assists in the axial deformation of the seal in response to axially-directed force. One of the sealing surfaces engages a corresponding surface of an internally threaded nut or housing. The component is engagable with an externally threaded port via the internally threaded connector. The anterior end of the seal fits over the port and a sealing surface of the seal is capable of sealing axially against a shoulder of the port while the seal body covers the otherwise exposed externally threaded port.

Abstract: A device for use with coaxial cable to attenuate sheath currents associated therewith. The device is adapted to be coupled to incoming and outgoing coaxial cables and includes a ferrite core configured as a first hollow cylinder mounted coaxially within a housing configured as a second hollow cylinder. A conductor within the housing has opposite ends positioned for electrical contact with the incoming and outgoing coaxial cables and an intermediate portion passing through the ferrite core longitudinally at least twice, being passed back over the outside surface of the core between passes therethrough. The elements are so dimensioned that the outside diameter of the housing is less than one inch, thereby allowing side-by-side mounting of a plurality of the devices on industry-standard, multi-port taps which have center-to-center spacings of one inch.

Abstract: A cable system, and a method for configuring a path of a cable system, wherein the group delay caused by one or more amplifiers having diplex filter networks is substantially equalized over all frequencies within a predetermined band by the use of one or more all-pass delay equalizers. A method of configuring a path includes steps of determining a delay versus frequency characteristic of the path within the predetermined frequency band, and providing from one to a plurality of all-pass delay equalizers in the path, wherein a collective delay versus frequency characteristic of the all-pass delay equalizer(s) within a predetermined frequency band is a mirror image of that caused by the amplifier(s), such that all frequencies within the predetermined frequency band are delayed by substantially the same amount and hence all frequency components of a signal arrive at a receiver at substantially the same time.

Abstract: The present invention provides an over-voltage surge protection device comprising a printed circuit board having a signal carrying conductive member having a plurality of nodes positioned therealong, and a conductive member running to ground also having a plurality of odes positioned therealong. The nodes on the signal carrying member and ground member extend along a common path with corresponding ones of the signal carrying nodes positioned in adjacent, but spaced relation to the ground nodes. The peripheral edges of the nodes accumulate and discharge transient high voltage surges. Preferably the nodes are shaped in the form of triangles due to this particular geometry's favorable ability to accumulate and discharge voltage, but may be formed in a variety of geometries.

Abstract: An F-type connector for mounting to a prepared terminal end of a coaxial cable for threaded engagement of a nut on the connector to a threaded shaft at a port on video equipment to which the coaxial cable is to be electrically connected. Prior art connectors of this type typically required as many as six or more revolutions of the nut to bring a metal post of the connector into contact with the end of the metal shaft to provide a properly shielded coupling of the connector and video equipment. In the connector of the present invention, the nut is mounted for limited axial movement with respect to the post, body and compression ring. A coil spring biases the nut toward a rest position with respect to the other elements wherein not more than three revolutions of the nut into engagement with the shaft are necessary in order to bring the post of the connector into contact with the shaft on the equipment, providing a satisfactory coupling.
