A signal distribution system to save on the cost of cable modems for cable TV headend operators who wish to deliver broadband digital data services, DSL, video-on-demand or POTS service over their HFC CATV delivery networks. All species within the genus have a shared cable modem and a filtration and combining circuit comprised of a plurality of diplexer filters or junction boxes or both which mix baseband packet data with analog CATV signals onto coax drop lines coupled to the various subscribers and connect POTS or DSL signals onto twisted pair portions of siamese cables. Various species have the cable modem feeding digital data or packets of DOCSIS or other data or digitized DSL signals sent over the HFC to the cable modem or digitized POTS signals send over the HFC to the cable modem to either a packet switch, a DSL concentrator, a voice-over-IP gateway or some combination of the above. This data is either delivered to each subscriber as LAN packets or analog POTS signals or DSL signals or some combination of the above using coaxial cable or siamese cable drop lines.

An electrical connector that is integrated within an active cable at one end of the active cable, wherein the active cable is configured to communicate over much of its length using one or more optical fibers.

An active cable that includes an integrated electrical connector at one end and an optical connector at the other end, and one or more optical fibers disposed therebetween to facilitate optical communication over much of the length of the active cable. The communication may be one direction or even duplex.

The present invention provides parallel, cable based robotic manipulators, for use in different applications such as ultra high-speed robots or positioning devices with between three to six degrees of freedom. The manipulators provide more options for the number of degrees of freedom and also more simplicity compared to the current cable-based robots. The general structure of these manipulators includes a base platform, a moving platform or end effector, an extensible or telescoping central post connecting the base to moving platform to apply a pushing force to the platforms. The central post can apply the force by an actuator (active), or spring or air pressure (passive) using telescoping cylinders. The robotic manipulators use a combination of active and passive tensile (cable) members, and collapsible and rigid links to maximize the benefits of both pure cable and conventional parallel mechanisms. Different embodiments of the robotic manipulators use either active cables only, passive cables only, or combinations of active and passive cables. An active cable is one whose length is varied by means of a winch. A passive cable is one whose length is constant and which is used to provide a mechanical constraint. These mechanisms reduce the moving inertia significantly to enhance the operational speed of the robots. They also provide a simpler, more cost effective way to manufacture parallel mechanisms for use in robotic applications.

An adaptor that mechanically and/or electrically adapts to and/or from an electrical connector that is integrated with an active cable at one end of an active optical cable, wherein the optical cable is configured to communicate over much of its length using one or more optical fibers. The cable may be an electrical to optical cable, and electrical to electrical cable, or one of many other potential configurations.

An active cable that is configured to communicate over much of its length using one or more optical fibers, and that includes an integrated electrical connector at at least one end. The active cable includes an integrated eye safety controls to thereby reduce the chance of injury should the active cable be severed, or otherwise unplugged at an optical end, if any. The cable may be an electrical to optical cable, and electrical to electrical cable, or one of many other potential configurations.

A heating and distributed-temperature-sensor cable permanently fixed in a wellbore that permits known amounts of heat to be introduced to subsurface formations and improved temperature measurement thereof. The heat is introduced into a target zone of the wellbore by forming the cable in two sections: an upper section that carries an electrical current without generating significant amounts of heat, and a lower section that generates heat from the electrical current. Continuous distributed-temperature-sensing is performed through measuring various scattering mechanism in optical fibers that run the length of the cable.

A switch is inserted and connected between a first portion and a second portion of an HPD line. The switch connects the first portion to the second portion when an HPD signal is outputted to the second portion. The switch cuts off the connection between the first portion and the second portion when the HPD signal is not outputted to the second portion. An AND gate generates a connection state detection signal that represents the connection state of an HDMI optical active cable, and outputs the connection state detection signal to a switch.

An active cable that is configured to communicate over much of its length using one or more optical fibers, and that includes an integrated electrical connector at at least one end. The active cable includes an integrated retiming mechanism. Thus, multiple links of cable may be used while reducing the chance that the jitter will exceed allowable limits. The cable may be an electrical to optical cable, and electrical to electrical cable, or one of many other potential configurations.

An active cable assembly for use in Universal Serial Bus (USB) that includes at least one USB node, the cable assembly managing power delivered through the cable assembly.

An active electric cable assembly suitable for high speed communication (e.g., 10 Gbit/sec) between electronic devices, such as but not limited to a peripheral device (e.g., storage device, docking station, etc.) and a computing platform expansion bus.

Methods and systems to detect topographic fraud are provided herein. The system includes a Cable Modem Termination System (CMTS) to periodically poll active cable modems and generate polling data. The system also includes a processor and a memory coupled to the CMTS. The processor is configured to, based on instructions in the memory, periodically determine a current geographic location for each polled cable modem based on the polling data from the CMTS, determine a geographic radius within which each polled cable modem is to be operated in and determine cable modems whose current geographic location is outside of their geographic radius.

According to one embodiment, an active cable assembly may include a cable end, a data receiver, a controller characteristic circuit, and a controller. The data receiver, operable to receive a DC-balanced data signal, can be electrically coupled to a conductive input data line of the cable end.
