A nonvolatile memory device includes a trimming cell array storing trimming data for a plurality of operating modes, a trimming cell sense amplifier sensing the trimming data and a trimming cell latch storing the sensed trimming data. The arm includes a measurement probe having an integrated line laser scanner mounted thereon. At least one proximity sensor and at least one magnetometric sensor is further placed inside the housing, and filters are connected on the signal path between the accelerometer and the sensors and position analysis and identification module. A linked list is composed of entries in the control structure; each entry stores a value identifying the next control entry in the list and a memory bucket associated with the entry. Each of the connecting plates further includes an insulting pad. The telepresence system is in signal communication with the Internet and a wireless communication network.
