An active terminating device (30) for an electrical transmission line with optional line-receiving and line-driving capabilities. The basic device is a two-terminal unit, denoted as a Signal Canceling Unit (SCU), which sensesthe signal available at its terminals (34a, 34b), and applies negative feedback in order to cancel and absorb the signal. When applied to the end of a transmission line (15a, 15b) as part of wired communication network, the SCU functions as a terminator. When connected in the middle of such wired transmission line, the SCU splits the transmission line into two separate and isolated segments. In such a configuration, the SCU can be used to isolate a portion of a network from signal degradation due to noise or bridge-tap. Furthermore, the two isolated segments may each employ independent communications, such that no interference exists between the segments. In another embodiment, line receiver functionality is integrated into the SCU, designated as a Signal Canceling and Receiving Unit (SCRU) (90). The SCRU can perform all the SCU functions, and also serves as a line receiver in the communication network. In yet another embodiment, line driver functionality is integrated into the SCRU, designated as a Signal Canceling, Receiving and Transmitting Unit (SCRTU) (120). The SCRTU can perform all the SCRU functions, and also serves as a line driver in the communication network. Upon connecting multiple SCRTU's to a continuous transmission line, terminated independent point-to-point communication segments are formed.

The invention relates to a vector point spatial data full-blind watermarking method based on grid dividing. The transform domain watermarking algorithms have the characteristic of being high in robustness. At present, most transform domain watermarking algorithms specific to linear vector space data and planer vector space data are characterized in that a watermark is embedded with a geometric object as a unit, but geometric objects of point spatial data are all independent points, and the situation that the transform domain watermarking algorithms are directly applied to the vector point spatial data watermarking can be difficultly achieved. If the whole of the point spatial data serves as a geometric object and a watermark is embedded in the geometric object, extraction of the watermark can be influenced by adding and deleting spatial points.
