Abstract: A sieve bed assembly monitoring system is disclosed. The system includes a sieve bed assembly including a canister having an intake; adsorbent material to produce oxygen enriched air from compressed air in a swing adsorption process; and an identification device including identification data for the sieve bed assembly, wherein the identification data is capable of uniquely identifying the sieve bed assembly. The system includes an oxygen concentrator having a retention mechanism to retain the sieve bed assembly, a compressor supplying compressed air to the intake of the canister, a controller, a transceiver and a reader operable to read the identification data from the identification device. The controller reads the identification data and transmits the read identification data via the transceiver. A remote external device receives the read identification data from transceiver.

Abstract: Systems and techniques for applying a pulsed electromagnetic field to body include: Self-contained portable pulsed electromagnetic field generating device which creates electromagnetic pulses given to feet and hands of the body. This device includes an electromagnetic field generator to provide power, device base to receive pulses from feet and device bulb to receive pulses from hand, thereby increasing energy of cells in the body.
