An embodiment of the invention includes a non-transitory computer-readable medium storing instructions that, when executed by a computer, cause the computer to carry out a method for scheduling at least one activity to achieve a time-varying energy balance of a power system. A mission plan for a mission is received. The mission plan includes at least one activity and at least one route. Each route of the at least one route includes at least one time and at least one location. A plurality of power load identifications is received for at least one time-varying power load for use in the mission plan. A plurality of energy storage device identifications is received for at least one energy storage device. Based on the plurality of power load identifications, a power requirement required to complete the mission plan is determined using the at least one power load. Based at least in part on the mission plan and the plurality of energy storage device identifications, an available power for the mission is determined. The at least one activity along the at least one route is scheduled based on the power requirement and the available energy.

Method for estimating the time-varying energy balance of a collection of energy sinks, harvesters, and storage devices

Disclosed herein is a system comprising: a hydrogen fuel cell; a fuel storage tank; a regulator coupled to the storage tank and the fuel cell; an electronic auto pilot; a rechargeable battery; a power electronics module for delivering power from the fuel cell to the autopilot and the battery; and a heat exchanger coupled to the fuel cell. The fuel cell is characterized by: a minimum continuous power output of no more than 25 W; a maximum continuous power output of no less than 5000 W; a specific power of at least 200 W/kg based on the mass of the fuel cell and any control electronics, cooling components, air delivery components, and water management components; an ability to operate at least 2 psig of hydrogen at an inlet; and an ability to operate at temperatures up to 90&#xb0; C.

Hydrogen fuel cell propulsion system

A computer-readable medium storing instructions that, when executed by a computer in a vehicle, cause the computer to carry out a method for determining an energy-optimal path for the vehicle from an initial location to a final location, the vehicle corresponding to a vehicle energy model. Based at least on the initial location, an initial time, the final location, the vehicle energy model, and an environmental forecast a global path is generated. The global path includes a final maximum net energy path and a plurality of waypoints. Based on the global path a local path from the present location to a next waypoint of the plurality of waypoints is generated. Whether a net energy gain is generated by a deviation from the global path to the next waypoint of the plurality of waypoints is determined. Generating a local path is repeated until the vehicle reaches the final location.

Method for identifying optimal vehicle paths when energy is a key metric or constraint

An embodiment of the invention includes a computer-readable medium storing instructions that, when executed by at least one computer, cause the at least computer to carry out a method for estimating a time-varying energy balance of a power system. A mission plan for a mission is received. The mission plan includes at least one activity and at least one route. Each route of the at least one route includes at least one time and at least one location. A plurality of power load identifications is received for at least one time-varying power load for use in the mission plan. A time-varying power requirement to complete the mission plan is determined. A baseline plurality of energy storage devices required to satisfy the time-varying power requirement is determined by the energy analysis code. The baseline plurality of energy storage devices includes a baseline number and type of energy storage devices.

A fuel cell includes a catalyst coated membrane with a proton exchange membrane, a cathode layer disposed on a first surface of the proton exchange membrane, and an anode layer disposed on an oppositely disposed second surface of the proton exchange membrane. At least one gas diffusion layer is bonded to at least one of the cathode and anode layers of the catalyst coated membrane. At least one bonding layer substantially surrounds at least one of the catalyst coated membrane and the at least one gas diffusion layer. The at least one bonding layer is bonded to a portion of the proton exchange membrane. At least one circuit is bonded to a portion of the gas diffusion layer and a portion of the at least one bonding layer.

Stackless fuel cell

A method and apparatus for the detection of pits and abnormalities in various stone fruits. The apparatus transmits a first plurality of beams of light (18) across inspection zone (14) and transmits a second plurality of beams of light (22) across inspection zone (14) in a direction opposite to beams of light (18). As a stone fruit (10) passes through inspection zone (14), a first plurality of sensors (32) and a second plurality of sensors (34) detect the variations in the intensity of the transmitted beams of light. The light transmittance and reflectance characteristics of the stone fruit are analyzed to detect the presence of a pit or internal or external abnormality.

Method and apparatus for detecting pits in fruit

A method and apparatus for non-destructive internal and external inspection of produce, including the detection of pits in various stone fruits. The apparatus transmits a first plurality of beams of light (20) across inspection zone (14) and transmits a second plurality of beams of light (30) across inspection zone (14) in a direction transverse to beams of light (20), thus forming an X-Y plane. As article of produce (10) passes through inspection zone (14) along the Z-axis, a first plurality of sensors (24) and a second plurality of sensors (34) detect the variations in the intensity of the beams of light and the data is processed to produce a three-dimensional 'picture' of the article of produce. Size, symmetry, external defects, and internal structure are determined as a result of processing the data collected. The apparatus and method can be used for detecting pits or surface defects, and for sorting or rejecting articles of produce based on size, symmetry, external defects or internal structure.
