Abstract: A method for generating liquefied gas is provided. The method includes receiving air, refining the air to create refined air, performing liquefaction on refined air to form liquefied gas, and transferring at least one constituent liquefied gas of the liquefied gas to a storage tank in a lighter than air aircraft. The constituent liquefied gas(es) is configured to serve as an energy source for the lighter than air aircraft. The method may include distilling the liquefied gas to obtain liquid nitrogen and one or more other constituent gases. The liquid nitrogen may be configured to store at least 250 kilojoule per liter of energy. Additionally, the air may be refined to create refined air by compressing the air, separating water from the air, scrubbing carbon dioxide from the air, and/or filtering dust from the air. The method may be carbon-neutral or carbon-negative.

Abstract: A control panel for an appliance is provided. The control panel can be produced by providing a dielectric substrate having a front surface and a back surface, printing a conductive ink onto the back surface of the dielectric substrate, curing the conductive ink such that the conductive ink forms a plurality of capacitive sensors on the back surface of the dielectric substrate, and positioning the dielectric substrate on the appliance such that the front surface of the dielectric substrate faces outwardly.

Abstract: A microwave oven comprises a cooking cavity and a RF generation module configured to deliver microwave energy into the cooking cavity. A controller is operatively associated with the RF generation module.

The controller is configured to at least temporarily block the signal when the RF generation module is activated if a frequency of the signal is at least partially degraded by a frequency of the RF generation module.

Abstract: A computer-programming tool for generating an implementation of a first data structure, the first data structure representing at least a portion of a computer-programming language. The implementation includes a second data structure and implementation rules which define the syntax rules of the first data structure to be enforced in relation to nodes of the second data structure during a subsequent processing operation which utilizes the implementation in order to establish compliance with the syntax rules represented by the first data structure. Links between nodes of the first data structure are representative of paths of inheritance of substitutability but not implementation and interface between those nodes.
