摘要:
This disclosure relates to a device and system capable of producing electricity by using a temperature gradient and a dual-phase fluid to convert thermal energy into electrical energy. The system relies on a sealed enclosed volume that utilizes a thermal gradient to vaporize and condense a dual-phase fluid. The cycle of the fluid transforming between the two phases is used to turn a turbine to create electricity. The thermal gradient can be enhanced using energy input from the sun.

The present disclosure includes various apparatus, system, and method embodiments for vehicle energy absorption. One embodiment includes an inflatable structure for impact of a vehicle thereon and one or more cords coupled to one or more deflation vents on the inflatable structure, where at least one of the one or more cords is an activation mechanism to activate the deflation vent upon impact of the vehicle.

A variable orifice valve provides a changing orifice dimension based solely upon the temperature or other property of the fluidic medium, such as flow-rate of the fluidic medium passing through the valve, and is actuated via a thermally active wire or flow-rate activated spring, for example, immersed in the fluidic medium.

A heat transfer device generally includes a flexible cooling layer for use in heat pipe technology for example. The flexible layer has outer and inner surfaces. A backing layer has an outer surface and an inner surface facing the inner surface of the flexible layer. A rigid separator portion is disposed between the inner surfaces of the flexible and backing layers, and has inner and outer surfaces. The inner surfaces of the flexible and backing layers and the rigid separator portion define a sealed chamber. An evaporable working liquid is contained within the sealed chamber. The working liquid expands when heated to expand a volume within the sealed chamber, such that the flexible layer extends away from the sealed chamber. The flexible layer, when extended transfers heat through the sealed chamber to a cooler area of the device.

A direct ocular virtual 3D workspace (laser-based 3D display system) utilizes traditional binocular methods of image composition to produce a 3D workspace in the observers' psyche. This direct ocular virtual 3D workspace is implemented such that in moving environments, such as on a ship or vehicle, the immersion of the individual into the display environment will not result in vertigo and/or motion sickness. This is resolved by utilizing a system that accomplishes eye-tracking, and produces the display image within the eye by means of laser projection. Two images can thus be projected into an individual's eyes to produce a 3D holographic-like image space. The individual will still maintain partial vision, resulting in a holographic-like display in space that the observer can look through. The images provided to multiple collaborators/users are geometrically corrected for each collaborator.
摘要:
A shock-isolation system having a platform for supporting an operator station and a console which can both be fixedly secured to the platform in a relative non-displacement mode with the platform supported by a shock mount that simultaneously isolates the platform including an operator, the operator station and the console as a unitary component from high “g” shock to thereby minimize injury to an operator due to impact with either the operator station, the console or the platform.
摘要:
A method of positioning an optoelectronic device, for example a vertical cavity surface emitting laser, onto an optical fiber connector and maintaining that exact alignment while testing the quality of the optical output prior to applying an adhesive to make the interface permanent. The method includes the utilization of a multi-piece fixture which clamps the elements into position, allows for testing, and provides a fixture to maintain position throughout the curing process.
摘要:
A product application control system having at least one distributed network. Each distributed network includes at least one independent control module for controlling at least one activator device. The system includes a central processor which has a process distribution controller which monitors the level of processing activity of the central processor. The responsibility for processing objects is maintained in the central processor so long as the level of processing activity in the central processor does not exceed a predetermined target level. If the target level is exceeded the process distribution controller causes responsibility for processing one or more objects to be downloaded to at least one independent control module.

A variable rate fertilizer spreading apparatus for spreading a precise amount of multiple types of fertilizers upon a field based upon a location in the field. The system comprises a controller accessing a soil map indicating the type of soil for each portion of the field, several fertilizer maps storing the desired fertilizer level of each of the fertilizers stored in product bins on the tractor, and several status maps each indicating the current fertilizer level at various locations of the field to be fertilized. By accessing the speed of the tractor via a speed indicator, and ascertaining the location of the tractor in the field via a position locator, such as an LORAN or GPS system, an expert system determines the dispensing rate of each of the fertilizers based on the various maps and the position and speed indicators such that the proper dispense rate of the fertilizers from bins is set to attain the desired level of fertilizers. The expert system accesses standard and proprietary data tables and processes complex calculations taking into account the interaction effects of multiple fertilizers being dispensed upon a particular type of soil, as ascertained from the soil map. Thus, each portion of a field can be characterized and fertilized such that the resulting level of each of the fertilizers matches the fertilizer maps after spreading fertilizer, where no predetermined path of vehicle is necessary. The current fertilizer level map is updated after a dispensing pass to provide a real-time record.
摘要:
An unmanned aerial system (UAS) is described that is operable on or in water, in addition to being able to fly in the air. The UAS can float in a body of water, or submerge itself underneath the water, and then later launch from the water without human intervention to perform a flying mission. The UAS can then return back to the water. The UAS incorporates an electric ducted fan acting as the propulsion engine for the UAS in the water as well as in the air.
