An MTJ cell without footings and free from electrical short-circuits across a tunneling barrier layer is formed by using a Ta hard mask layer and a combination of etches. A first etch patterns the Ta hard mask, while a second etch uses O2 applied in a single high power process at two successive different power levels. A first power level of between approximately 200 W and 500 W removes BARC, photoresist and Ta residue from the first etch, the second power level, between approximately 400 W and 600 W continues an etch of the stack layers and forms a protective oxide around the etched sides of the stack. Finally, an etch using a carbon, hydrogen and oxygen gas completes the etch while the oxide layer protects the cell from short-circuits across the lateral edges of the barrier layer.

A state of charge (SoC) a lithium-ion (Li+) battery is estimated at a time instant by first constructing a model of the Li+ battery based on a single particle operation. The model describes a relationship between the SoC, a charge current, a discharge current, and an output voltage. Using a nonlinear optimization, a function expressing a relationship between the SoC and an open circuit voltage is determined. The relationship is based on off-line measurements of the charge current, the discharge current, and the open-circuit voltage. Then, the SoC and parameters of the model are estimated concurrently, wherein the SoC and the parameters are based on the model, the function, and on-line measurements of the charge current, the discharge current, and the output voltage.

A method for controlling an adsorption unit and associated compressor that adjusts the flow rate of a compressed feed stream produced by the compressor so that it increases from a nominal flow rate and then decreased back to the nominal flow rate. The increase and decrease of the feed stream flow rate are controlled in accordance with increase and decrease rate functions of adsorbent bed pressure ratio between off-line and on-line adsorbent beds and a triggering pressure ratio at which the feed flow rate decreases. Each of the increase and decrease rate functions is tuned to produce a similar response in the flow of a product stream produced by the adsorption unit. Additionally, repressurization time is controlled by driving it toward a target value that allows the purge stage of regeneration to be maximized and therefore, the degree to which each of the adsorbent beds is regenerated.
