Abstract: Disclosed herein is a rack ear for mounting equipment in an equipment rack. The rack ear can include a member that extends outward from a computing device, when the rack ear is coupled to the computing device, to an end of the member. The member can include an elongate opening that extends through the member and defines an upper lobe and a lower lobe. The elongate opening can extend through the end of the member to define a slot opening. The elongate opening can be symmetrical about a plane through the horizontal midline of the member. The member can define a height that corresponds to a 1U, 2U, 3U, or 4U dimension of the computing device.

Abstract: Systems, circuits, and methods are disclosed herein for charging (recharging) one or more batteries of an electric vehicle through an on-board charge shaping (or tuning) circuit. The charge shaping circuit may alter the charge signal received from a charging station and/or a regenerative charge signal from the vehicle motor based on one or more charge conditions at the battery. The charge shaping circuit and/or a motor controller/inverter of the electric vehicle may include circuitry that is controllable to generate a shaped power signal in a similar manner as above, with or without the charge shaping circuit discussed above. In some implementations, one or more heat transfer systems may be included to transfer heat generated from the battery charging system to the battery.

Abstract: The disclosure provides a method comprising inducing a first current between a source of a countercharge and a first electrode, the first current being through an electrolyte. A second current is induced across the first electrode, the second current being transverse to the first current, and the second current inducing a relativistic charge across the first electrode.

Abstract: A method, and associated batteries and battery charging units, that involve inducing electric and/or magnetic fields (field-induced current) across an electrode of a electrochemical cell, such as an anode of a battery. The field and current across the electrode may be referred to herein as a transverse current as this current is typically transverse to the ionic charge current that may be applied when charging a battery. The field and current may be induced from connecting AC energy, e.g., AC current, across the electrode or at a discrete point or points of the electrode. The induced field and current may suppress dendrite growth, experienced in conventional batteries without AC energy, among other advantages.
