An injection molding machine includes an edge gate nozzle with a nozzle body having a primary melt channel and a nozzle head having first and second secondary melt channels that feed melt to first and second nozzle tips. First and second heaters are disposed in the nozzle head to provide heat to the secondary melt channels. In some embodiments, the heaters are positioned adjacent to the secondary melt channels, with first heater is closer to the first secondary melt channel than to the second secondary melt channel. In some embodiments, the heaters are positioned adjacent to the nozzle tips, with the first heater closer to the first nozzle tip than to the second nozzle tip. In some embodiments, each heater is adjacent to both the respective nozzle tip and secondary melt channel. In some embodiments, each heater is individually controllable.

A melt distribution device () including a heat-receiving part () and a heater (). The heater () is coupled to the heat-receiving part () so to maintain thermal communication between the heater () and the heat-receiving part (). The heater () is also coupled to the heat-receiving part () so to isolate, at least partially, the heater () from receiving stress and strain transmission from the heat-receiving part ().

A hot-runner system for use with an injection molding system, the hot-runner system including a hot-runner component, a material; and carbon nanotubes being combined with the material. The carbon nanotubes are dispersed, at least in part, in the material and the material includes a metal alloy. The carbon nanotubes are dispersed in the metal alloy, so that the metal alloy and the carbon nanotubes are combined to form a CNT-metal composite material.

A magnetic on-off robotic attachment device (MOORAD) () is used to make a number of systems, such as a mobile apparatus ('), a belt mechanism () and a sensor device (). The MOORAD allows the respective system to be removably magnetically attached to a ferromagnetic structure/object (A-B,A&#x2032;-B&#x2032;,). Each MOORAD generally includes a dipole magnet (A-B,) movable relative to first and second ferromagnetic portions (A-D,) that are separated by corresponding magnetically insulating portions (A-C,) so as to change that MOORAD between off and on states.

A thermoelectric device () that includes at least one thermoelectric couple () that contains a thermoelectric junction () between two dissimilar materials (P, N) that allow exploitation of either the Seebeck effect or Peltier effect of the junction. The thermoelectric couple includes two thermoelements () that extend between the hot side () and cold side () of the device. Each thermoelement has a thermally insulating region () that insulates the hot side from the cold side and an electrical energy storage device () that stores electrical energy. When operating in a Seebeck mode, each storage device may be periodically discharged by harvesting circuitry () so as to harvest the energy stored therein. When operating in a Peltier mode, each storage device may be periodically charged by charging circuitry () so as to induce a temperature change at the thermoelectric junction.

A system () for damping vibrations of a vibratory structure (). The damping system includes an active damper (), a vibration sensor (A'-C&#x2032;), and a controller () for controlling the active damper in a manner that damps vibration of the vibratory structure. In some embodiments, the active damper comprises an active mass (A&#x2032;-C&#x2032;,A&#x2033;-C&#x2033;) and an actuator () for controlling the movement of the active mass. In other embodiments, the active damper comprises a flexural damper ().

Self-healing cable apparatus and methods are disclosed. The cable has a central core surrounded by an adaptive cover that can extend over the entire length of the cable or just one or more portions of the cable. The adaptive cover includes a protective layer having an initial damage resistance, and a reactive layer. When the cable is subjected to a localized damaging force, the reactive layer responds by creating a corresponding localized self-healed region. The self-healed region provides the cable with enhanced damage resistance as compared to the cable's initial damage resistance. Embodiments of the invention utilize conventional epoxies or foaming materials in the reactive layer that are released to form the self-healed region when the damaging force reaches the reactive layer.
