LIMIS systems, devices and methods

A monitoring and control system comprising at least one each of an active transceiver (AT) means associated with passive transceiver (PT) means, each being adapted for at least one of electromagnetic radiation (EMR) and sound communication with the other within predetermined distances;

• and each including computing means and alterable computer memory means,
• said AT means being further adapted for at least one of (a) transmission of coded interrogation signals;
• (b) calculation, from identification signals transmitted by the PT means, of the location of, the identification of, the motion of, and the count of the said PT means;
• (c) control of devices associated with PT means and (d) transmitting encoded PT memory alteration codes,
• each PT means further comprising computing means having memory means including at least one form of alterable ROM and means for altering memory means on receipt of at least one PT memory alteration code from an associated AT means and means for transmitting at least one predetermined identification signal only after the receipt of a coded interrogation signal from an associated AT means.
