An embodiment vibration dampening device includes a stack of permanent magnets having a plurality of cross-sectional areas, wherein the permanent magnets are electrically coupled in series with each other. The device further includes an insulating sheath disposed around the stack of permanent magnets, and a visco-elastic polymer disposed within the sheath and around the stack of permanent magnets.

The present invention is a signal cable for transmitting the signal between the transmitter and the receiver, providing an electrical connection by a connecting part, wherein said connecting portion comprises a layer of graphene disposed on a polymer layer, characterised in that it comprises two conductors, wherein each conductor includes a connecting portion arranged in a protective insulating layer (3) and the coupling portion takes the form of a tape, in which the graphene layer (1) is disposed between two polymer layers (2).

A cable having low values for resistance, inductance, and capacitance. The cable includes a plurality of conductors for each signal or leg, which may be configured as a braid of three subsets of braids of bonded pairs of insulated conductors. The bonded pairs may be twisted or untwisted, in close proximity such that inductance is reduced via magnetic field cancellation. Each leg may be separate and parallel, rather than interwoven or braided together, increasing the distance between the two signals and reducing capacitance. The legs may be positioned close to each other, such that their magnetic fields cancel to further reduce inductance.

A system includes processing circuitry communicatively coupled to a coaxial cable as well as a sensor, such as a light detection and ranging (LIDAR) sensor communicatively coupled to an unshielded twisted pair (UTP) cable. The processing circuitry and LIDAR sensor may be communicatively coupled to one another via a UTP-to-coaxial converter that is communicatively coupled to both the coaxial cable and the UTP cable. The UTP-to-coaxial converter includes filter circuitry configured to receive one or more signals generated by the LIDAR sensor and generate one or more filtered signals by blocking a portion of the one or more signals having a frequency in a first frequency range. The UTP-to-coaxial converter is configured to send the one or more filtered signals to the processing circuitry via the coaxial cable.
