Abstract: Systems, devices, methods, and techniques for self-correcting current measuring are disclosed. Advanced material inductive measuring devices can obtain a reading of a monitored current in a monitored source. The advanced material allows the measuring device to operate at low temperatures disproportionate to saturation levels. Readings by the measuring device that are beyond a top-end limit of the measuring system or otherwise outside of a desired band can be transformed or transposed by employing a transformation to correct the reading to be within an acceptable ratio error band.

Abstract: This invention includes a tapered electrode assembly for providing a crumple zone in a rechargeable cell. The taper, which may be curvilinear, angular or piecewise linear, allows a void to exist between the corner of the metal can and the electrode assembly. This “crumple zone” prevents any external damage to the can from damaging the internal electrode assembly. The invention facilitates passage of common OEM drop testing without compromising cell performance or energy storage capacity. The invention increases the reliability of the cell by allowing the cell to resist external impacts.

Abstract: A switchable power supply includes a moveable electrical plug holding member that has a first position, which places an electrical plug pair in position for use with a first voltage standard, and a second position, which places the electrical plug pair in position for use with a second voltage standard. A switch is in a first state when the moveable electrical plug holding member is in the first position and is in a second state when the moveable electrical plug holding member is in the second position. When the switch is in the first state, a voltage modifier circuit generates a first output voltage and when the switch is in the second state, the voltage modifier circuit generates a second output voltage.
