A method of providing visual information to a human viewer includes the steps of defining a range of distances from a surface and a range of viewing angles with respect to the surface, determining the location and viewing angle of a human viewer with respect to the surface, and providing a virtual image to the human viewer via a visual display device worn by the human viewer when the location and viewing angle of the human viewer with respect to the surface is determined to be within the defined range of distances and viewing angles, such that the virtual image is perceived to be defined on the surface by the human viewer.

A power generation system includes a fuel cell including an anode that generates a tail gas. The system also includes a hydrocarbon fuel reforming system that mixes a hydrocarbon fuel with the fuel cell tail gas and to convert the hydrocarbon fuel and fuel tail gas into a reformed fuel stream including CO2. The reforming system further splits the reformed fuel stream into a first portion and a second portion. The system further includes a CO2 removal system coupled in flow communication with the reforming system. The system also includes a first reformed fuel path coupled to the reforming system. The first path channels the first portion of the reformed fuel stream to an anode inlet. The system further includes a second reformed fuel path coupled to the reforming system. The second path channels the second portion of the reformed fuel stream to the CO2 removal system.

A fuel cell system includes: a power generation stack (1) composed by stacking a plurality of fuel cells (10); and a hydrocarbon-oxidizing device (2) disposed on an upstream side of the power generation stack (1) in a fuel supply passage (8). The hydrocarbon-oxidizing device (2) directly and electrochemically oxidizes hydrocarbons with a carbon number of 2 or more, which are contained in fuel gas, or decomposes the hydrocarbons and electrochemically oxidizes carbon obtained by decomposing the hydrocarbons.

An energy control apparatus for controlling hybrid energy sources for an aircraft is designed for determining an operating characteristic of an energy source, a demand of at least one first consumer for a first resource and a demand of a second consumer for a second resource. The energy control apparatus activates the energy source in dependence on the demand for the first resource and the second resource and, if there is no demand for a first or second resource that is generatable by the energy source and is present in excess, supplies a third consumer with the excess resource. This makes it possible for an energy system to operate different consumers independently of the type of generated resources and their dependencies during the generation.

The invention is using a hydrogen-containing solid as an energy storage material for naval and stationary uses. The system is designed and analyzed optimally for producing thermal energy necessary to dissociate magnesium hydride which in turn produces the needed hydrogen to operate a fuel-cell and meet the electricity demand. The collected hydrogen is used to power the various energy needs of the Navy as well as of homes. In addition, the solar thermal system may also be used to provide heat to hot water, and other heating needs. The system has an overall energy efficiency between 20% and 30% with both thermal and hydrogen storage capability for overall energy storage and provides smooth energy needs of a building.

The invention provides an operating method of a redox flow battery capable of grasping a charging state of the battery more reliably to stabilize an output capacity of the battery. The method is for operating the redox flow battery comprising a cell stack 1 comprising a plurality of cells. A selected cell(s) in the cell stack 1, to and from which positive electrode electrolyte and negative electrode electrolyte are supplied and discharged and which is/are not normally connected to a DC/AC converter 225, is/are in the form of an auxiliary cell 2 used for measuring a charging rate of the electrolyte. Also, a stop of charge of a main cell 3 and a stop of discharge of the main cell 3 are controlled with reference to a circuit voltage obtained from the auxiliary cell 2. Since the auxiliary cell 2 is integrally incorporated in the cell stack 1, the charging state of the battery can be grasped reliably without stopping the charge/discharge operation of the main cell 3. Also, since the stop of charge of the main cell 3 and the stop of discharge of the same are controlled with reference to the measured circuit voltage, the output capacity can be stabilized.
摘要:
A power regulator and a process regulator, or a power regulating device for regulating hybrid energy sources are provided for an aircraft. The power regulator and process regulator is equipped such that the requirement of a required means of a consumer is measurable. In this arrangement the power regulating device is equipped such that a first operating characteristic of a first energy source and a second operating characteristic of a second energy source are determinable. By means of the first energy source a first requirement share can be generated, and by means of the second energy source a second requirement share of the required means can be generated. The power regulating device can regulate the first energy source and the second energy source such that depending on the first operating characteristic and on the second operating characteristic the first requirement share and the second requirement share of the required means can be provided to the consumer.
