The prosthesis in 2050 would mean surpassing ordinary human strength. The future belongs to the trans-human and the power of machine integrated human body The US already has plans to bring cyborgs to the military. The future looks very bright for prosthetics. Gone are the days of where the amputees couldn't serve the nation after losing a limb.

The project was undertaken in our course module 'Design for 2050', wherein we started with studying what prostheses are, how it evolved from the time it was first introduced in 950–710 B.C. to the current research in the field. The main topics of our interest pertaining to this project are as follows -
1. Brain Computer Interaction(BCI)
2. Agonist-antagonist Myoneural Interface ...

This space-transportation-system proposal is a reusable, optionally-manned, modular spaceplane to transport payloads and/or personnel into low-earth orbit. The emphasis is to reduce the number of maintenance man-hours vs. flight-hours to drastically reduce 'turn-around' time, making the vehicle commercially viable. Another objective is to provide "zero-to-orbit" escape capability for manned missions to improve crew safety at the expense of payload capacity. Finally, the ability to operate as an Autonomous-Unmanned-Aerospace-Vehicle, launches significantly more payload can by into orbit; since space and mass for the modules and resources to support them are opened for payload.

The basic design is a variation of the Inverted-D lifting-body similar to the X-30 / X-43 designs; using a high-mounted, retractable, variable geometry (VG) wing and canard ...

The use and employment of small unmanned aerial systems (sUAS) in public safety and commercial applications has grown exponentially since their introduction into the consumer market. As of February 2020 there were over 436,633 registered commercial, public/government and other drones and 167,841 remote pilots certified.The advantage of using drones in these applications is their ability to carry a payload that usually consists of a high resolution video/still camera, FLIR, multi-spectral sensors or other data collecting sensors. The efficiency, effectiveness, and usefulness of these sensors and the resulting data is directly correlated to the pilot’s ability to precisely position the sensor within the spatial environment in relation to the mission target of interest. The responsibility of safely flying the ...

As the core of a modular, optionally-manned, single-stage-to-orbit, reusable, trans-atmospheric spaceplane; this combined-cycle engine which operates on JP-7 jet fuel, and either air or LOX; functions as an Expansion-Cycle Turbojet for takeoffs and landings (for noise reasons). Then transitions through Pulse-Detonation Turbojet, Pulse-Detonation Ramjet, Supersonic-Combustion Ramjet, and Pulse-Detonation Rocket as it accelerates into earth orbit. Thus, fulfilling the promise of the X-30 National Aerospace Plane, and an economically viable Space Transportation System feasible.

The engine uses expansion-cycle turbo-machinery (ala. REX-I&III) to drive the fuel and hydraulic pumps, generator, and selectively the axial-compressor or oxidizer pump. This is driven utilizing catalytic-regenerative-cooling of the combustion chambers, which endothermically cracks the JP-7 fuel down into Ethelene and Ethane; as done in the ...

Below is the equation for the resistance of a fluid flow system:
∆P/Ǭ=(q-W)/VǬ-ρ δv/Ā-(μA_⟘ dv_⟘)/ĀǬ-(ρA_h gδh)/ĀǬ
Where Ǭ is the total volumetric flow in the system; ∆P is the pressure difference across the system; V is the volume of the system; Ā is the area perpendicular to the flow; A⟘ and dv_⟘are the area and velocity difference parallel to the flow; Ah and δh are the area and height of the system relative to gravity.
Each term on the right of the equal sign represents:
The flow resistance due to energy (q) or work (W) done to or by the system.
-ρ δv/Ā
The flow resistance due to a velocity change δv
-(μA_⟘ dv_⟘)/ĀǬ
The flow resistance due ...

As per title drones can be used as a power bank to recharge the drying batteries of sensors.

A drying battery will send a signal to recharge it and the drone will be ready to fly to recharge the battery of sensor by detecting the location of sensor.

The drone can be designed in this way that it can recharge multiple batteries.

The drone can also be designed in this way that the drone can replace the drying batteries with already recharged batteries .but there will be requirements of some changes in the sensors.

We can also designed a Ground vehicle power bank like drone power ...

False alarms are a common problem with invisible laser based sensors.

In border areas it just creates panic to identification whether it is a human being, an object, dust, an animal or some vehicle moving across the border.

The proposed solution will work to neutralize false alarms through accurate identification.

It can easily identify what kind of object is moving across the border.

As per the sketch, if a human being is trying to cross the border then the invisible laser rays will work to make a pattern of "footstep or shoes of human being" on the both side of laser board after hitting the shoes or footstep, as after hitting with footstep the connection of laser lights will ...

Satellite communication (SATCOM) systems need to operate in challenging and hostile radio frequency (RF) environments in the presence of unintended and/or intended RF interferences (RFI). For military and commercial applications, it is important to develop advanced RFI mitigation and anti-jamming (AJ) capabilities. Key enabling technologies for such capabilities include advanced RF situation awareness and adaptive dynamic resource allocation (DRA).

The Intelligent Fusion Technology, Inc. (IFT) team has developed EDGES, an Electronic Defense Game-Theoretic Engine for SATCOM. A hardware add-on for SATCOM Ground Control providing Electronic Defense (ED) in hostile RF environments. EDGES performs per-hop in-service signal-to-noise (SNR) based RF situational awareness using dynamic game theory-based DRA algorithms. EDGES has been developed for the wideband global satellite system (WGS) and ...

What is HyALTA® - A hybrid lighter-than-air (LTA) and flying wing air vehicle that allows a single vehicle to provide the simplicity, vertical heavy lift, and extended efficient station keeping capabilities of an LTA with the high glide ratio (>40:1) and velocity (up to 200 kts.) of low coefficient of drag flying wings. This patented design (U.S. Patents 9,623,954/10,287,000/10.377,465/10,532,803 and other patents pending) is unlike other conventional or LTA aircraft.

How Does it Work – HyALTA® delivers these capabilities through an elegantly simple minimalist internal structure that morphs to provide extensive combinations of aspect ratio, chord thickness and top and bottom camber to achieve a wide range of aerodynamic and buoyant lift configurations. A gas impermeable inner bag provides ...
