According to one or more aspects, systems and techniques for hydrogen fueling with integrity checks are provided herein. Communicated parameters measured by on-board sensors of a vehicle may be cross-referenced against calculated parameters measured by sensors of a fueling station. For example, communicated parameters relating to a compressed hydrogen storage system (CHSS) tank of a vehicle to be fueled may be received at different time intervals. Calculated parameters may be calculated based on a mass of hydrogen fuel dispensed by a hydrogen fueling station from a reference point to one of the time intervals and densities of the CHSS tank of the vehicle at respective time intervals. An error may be calculated between the communicated parameters and the calculated parameters. A fueling mode, such as a conservative fueling mode or a non-conservative fueling mode, may be determined based on the calculated error.

In some embodiments, the illustrative method defines an engine cycle comprising several state changes that allow for a net gain of energy from an underlying source force field. The potential for a net energy gain via the method results from the discovery that a Casimir force system can be rendered non-conservative. This is done by appropriately altering one or more of a variety of physical factors that affect the Casimir force, or by altering any of a variety of environmental factors that affect such physical factors. In various embodiments, the extracted energy is stored, used to power energy-consuming devices or used to actuate a micromechanical device. In one embodiment, the method is implemented using an energy extraction apparatus that comprises two spaced Casimir force-generating boundaries that are operatively coupled to an energy transformation system. The energy transformation system includes a first device that is operable to alter at least one physical factor of the system. The energy transformation system also includes a second device that is operable to change the distance between the two Casimir force-generating boundaries, and further operable to maintain the distance between the boundaries while the first device alters the physical factor.

Computer-based computational tools for use in determining spatial charge distributions for biological systems that include one or more biological membranes are provided. At least one of the biological membrane includes at least two regions having different electrical properties, e.g., the biological membrane can include a pore having a higher conductivity than the surrounding bulk membrane. In other cases, the membrane can include non-active and active regions, with conservative fields acting at the non-active regions and a combination of conservative and non-conservative fields acting at the active regions. The non-conservative fields can, for example, originate from differences in ionic concentrations of the type which generate Nernst potential differences across membranes. Using the computer-based computational tools, charge distributions not previously known to exist have been discovered, e.g., ring-shaped charge distributions in the vicinity of an active pore.
