+While working on an application of inductive WPT in a Inertial Hardware Security Module (IHSM) as previously
 published by \textcite{gotteCantTouchThis2022}, we found ourselves presented with an unusual set of constraints
 attempting WPT through a rotating joint using a planar inductor implemented in a Printed Circuit Board (PCB)---a set of
 constraints that does not seem to be addressed adequately in the existing literature on inductive WPT yet.
 
 Inertial Hardware Security Modules are a hardware security primitive that discourages tampering with a payload such as a
 single-board computer by rotating a tamper-sensing enclosure around the payload. The tamper-sensing enclosure
-continuously monitors itself for tampering using sensors such as tamper-sensing meshes~\cite{TamperResistance2020a} and
+continuously monitors itself for tampering using sensors such as tamper-sensing meshes~\cite{TamperResistance2020} and
 accelerometers. When the tamper-sensing enclosure signals a tamper alarm to the payload, the payload immediately
 destroys all sensitive data to prevent the attacker from gaining access to it. In principle, an IHSM is similar to an
 ATM that responds to attempts at opening its vault by dispensing dye over the bank notes within, rendering them
 unusable.
 
-In our IHSM implementation, the tamper-sensing enclosure rotates at \qtyrange{1000}{3000}{\rpm}. The tamper sensing
-circuit on the rotating enclosure is powered through a pair of WPT inductors located on the IHSM's axis of rotation. The
-large centrifugal acceleration prohibits the use of batteries or liquid electrolyte capacitors on the rotating part, and
-makes heavy components such as large Multilayer Ceramic Capacitors (MLCCs) challenging to balance. Planar inductors that
-are patterned directly into a PCB provide a cost-effective and lightweight solution to this problem, but the coarse
-pattern resolution of PCBs results in a strict upper limit to the turn count that can be achieved in an inductor with a
-given area.

 Planar inductors are usually considered approximately axisymmetric. In our application, we found that the field
 asymmetry in feasible PCB inductors is large enough that axial rotation of two such inductors results in an oscillation
 of their coupling coefficient that leads to voltage ripple on the secondary side, especially when the coils are
 misaligned.
 
-In other inductive WPT systems, this issue is mitigated by one of several factors: First, for this effect to matter in
-the first place, the two coils have to be rotating with respect to one another. In ferrite core inductors, the core is
-the major factor shaping the magnetic field and evens out the small effect of winding asymmetry. In wire-wound
-inductors, the often higher turn count and the tightly packed, circular wires render this effect negligible. Finally,
-the output ripple caused by this oscillation can be filtered through a voltage regulator or by using a large decoupling
-capacitor on the secondary side if the application can accomodate such components on the rotating part.

 \subsection{Twisted inductors}
 
 In this paper, we propose a layout for circular PCB inductors that uses a number of series-connected interleaved spirals
 to achieve a topological equivalent to a torus knot from mathematical knot theory. Our layout twists the inductor's
 windings around one another by connecting the interleaved spiral segments with a ring of vias each on the inside and
-outside of the inductor's windings. Our approach provides better performance beyond our particular use case, and
-improves over conventional contemporary planar inductors applying similar principles to those which inspired  the
