A cover is configured to selectively engage with a portion of a structure in response to receiving a wireless electrical power signal at a receiver antenna of the cover from a wireless power source located in an outside environment, to separate a first environment on a first side of the cover from a second environment on a second side of the cover opposite the first side. In response to wirelessly receiving the electrical power signal, a fastening subassembly of the cover changes from a secured mode configured to inhibit opening a cover body with respect to the structure, to an unsecured mode configured to facilitate opening the cover body with respect to the structure. This in turn allows the cover to be matingly engaged with a portion of the structure to form a smooth continuous surface, without any exposed fasteners on the exterior side of the cover.

A turret system includes a base subassembly and a turret subassembly. The base subassembly includes a base housing and a first turret mounting interface coupled to the base housing. The base subassembly also includes a first antenna configured to wirelessly transmit an electrical power signal. The turret subassembly includes a turret housing and a second turret mounting interface coupled to the turret housing. The second turret mounting interface is configured to rotate with respect to the first turret mounting interface, thereby rotating the turret housing with respect to the base housing. The turret subassembly further comprises a second antenna configured to wirelessly receive the electrical power signal from the first antenna.

A thermal battery including a casing; a stack of cells disposed within the casing; a pressurizing element; an actuator when actuated, translates the pressurizing element to automatically engage and repressurize the stack of cells; and a latch configured to inhibit movement of the pressurizing element in a direction away from the stack of cells.

Control circuits with energy recycling for envelope elimination and restoration and related methods are disclosed. A control circuit includes a filter module configured to condition an input power signal to provide an output power signal. An energy recapture module is electrically coupled to the filter module and is configured to capture a portion of residual energy from the filter module and return the portion of the residual energy to the input power signal. A control module is electrically coupled to the filter module and the energy recapture module and is configured to control the filter module to provide the output power signal and is further configured to control the energy recapture module to capture and return the portion of the residual energy to the input power signal.

Power modules with reduced parasitic inductances are provided. A power module includes a first substrate including a first electrically-conductive layer and a second substrate including a second electrically-conductive layer. These substrates may be stacked on each other. A scalable network of power switches may be arranged on the substrates. Power bars may be connectable to the electrically-conductive layers through electromechanical interfaces at selectable interface locations. The locations and/or type of interface may be selectable based on the arrangement of the switches. The first and second electrically-conductive layers may be disposed on mutually opposed surfaces of a dielectric layer having a thickness chosen to effect a level of coupling between respective source and return current paths provided by the electrically-conductive layers. The level of coupling may be arranged to increase the mutual inductance within the power module, which can effectively reduce the formation of parasitic inductance in the power module.

An energy storage cell, or a plurality of energy storage cells assembled into an apparatus, are self-orienting relative to one or more adjacent energy storage cells. The energy storage cells are capable of sensing their polarity orientation of at least one other energy storage cell and self-orienting its own polarity responsive thereto. Thus, a method for self-orienting a subject energy storage cell includes: sensing the polarity of an adjacent energy storage cell; and setting the polarity of the subject energy storage cell responsive to the sensed polarity if the polarities of the adjacent energy storage cell and the subject energy storage cell are incompatible.
