A wedge-shaped connector for arranging and connecting seat modules in a predetermined spaced and angled relationship to form a non-linear modular seating array. In this context, after the authentication of the sensor, the random number or a part of the random number or a number obtained from the random number by a function is utilized for the time-variant parameters. Here, a position of the capillary 5 in a Z direction and a load detected by a load sensor 7 are detected and stored every predetermined time period. The hydraulic system has several configurations. Thus, the channel region makes a right angle with the trench or recess, and the channel region is bent. An example system includes a memory for storing computer executable instructions, and a processing unit for accessing the memory and executing the computer executable instructions.
