Active cables are copper cables for data transmission that use an electronic circuit to boost the performance of the cable. Without an electronic circuit a cable is considered a 'passive' cable. Passive cables are liable to degrade the data they carry, due to "channel impairments" including attenuation, crosstalk and group velocity distortion. In active cables, a circuit using one or several integrated circuits is embedded in the cable to compensate for some or all of these impairments. This active boosting allows cables to be more compact, thinner, longer and transmit data faster than their passive equivalents.

Active cable for wellbore heating and distributed temperature sensing
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.

Light weight parallel manipulators using active/passive cables
ActiveUS7172385B2Simple processMaximize the benefitsProgramme-controlled manipulatorMechanical apparatusUltra high speedCost effectiveness
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.

Integrated sensor cable for ranging
An intrusion detection system provides the function of an “active” ranging sensor cable system utilized for identification of the location of the intruder, with that of a “passive” cable detection system, in an integrated cable configuration. This dual function is provided with a single conventional sensing cable optimized for both “active” and “passive” sensing, or in combination with other parallel sensing cables for a “passive” cable component. The “active” cable component includes a coaxial sensor cable having a loosely disposed conductor. A signal is injected into the sensor cable such that a reflection is altered when an intrusion disturbs the cable. Based on the timing of the reflection, a processor, or a reflectometer, identifies the location of the disturbance. The “passive” cable component can be sensitized to detect intrusion via some other sensing phenomenology, such as the triboelectric effect, for triboelectric effect sensing.
