Who invented the dishwasher in 1850

From the top, the aircraft are the F, the U-2S, and the F Lockheed Martin. At least, that's the goal. The reality often falls short. The networks that knit together all these sensors are a patchwork. Some of them run over civilian commercial infrastructure and others are military, and among the military ones, different requirements among the different branches and other factors have contributed to an assortment of high-performance but largely incompatible communication protocols.

Messages may not propagate across these networks quickly or at all. Here's why that's a problem. Say that an F detects an incoming ballistic missile. The aircraft can track the missile in real time. But today it may not be able to convey that tracking data all the way to antimissile batteries in time for them to shoot down the projectile.

That's the kind of capability the 5G. MIL initiative is aiming for. There are broader goals, too, because future battlefields will up the ante on complexity. Besides weapons, platforms, and gear, individual people will be outfitted with network-connected sensors monitoring their location, exposures to biochemical or radioactive hazards, and physical condition.

To connect all these elements will require global mesh networks of thousands of nodes, including satellites in space. The networks will have to accommodate hypersonic systems moving faster than five times the speed of sound, while also being capable of controlling or launching cyberattacks, electronic warfare and countermeasures, and directed-energy weapons.

Such technologies will fundamentally change the character and speed of war and will require an omnipresent communications backbone to manage capabilities across the entire battlefield. The sheer range of coordinated activities, the volume of assets, the complexity of their interactions, and their worldwide distribution would quickly overwhelm the computing and network capabilities we have today. The time from observation to decision to action will be measured in milliseconds: When a maneuvering hypersonic platform moves more than 3.

Our 5G. MIL vision has two complementary elements. One is exemplified by the opening scenario of this article: the quick, ad hoc establishment of secure, local networks based on 5G technology. The goal here is to let forces take sensor data from any platform in the theater and make it accessible to any shooter, no matter how the platform and the shooter each connect to the network.

Aircraft, ships, satellites, tanks, or even individual soldiers could connect their sensors to the secure 5G network via specially modified 5G base stations. They could also share data via military tactical links and communications systems. In either case, these battlefield connections would take the form of secure mesh networks.

In this type of network, nodes have intelligence that enables them to connect to one another directly to self-organize and self-configure into a network, and then jointly manage the flow of data.

Inside the hybrid base station would be a series of systems called tactical gateways, which enable the base station to work with different military communication protocols. Such gateways already exist: They consist of hardware and software based on military-prescribed open-architecture standards that enable a platform, such as a fighter jet made by one contractor, to communicate with, say, a missile battery made by another supplier. The second element of the 5G. MIL vision involves connecting these local mesh networks to the global Internet.

Such a connection between a local network and the wider Internet is known as a backhaul. In our case, the connection might be on the ground or in space, between civilian and military satellites.

The resulting globe-spanning backhaul networks, composed of civilian infrastructure, military assets, or a mixture of both, would in effect create a software-defined virtual global defense network.

The software-defined aspect is important because it would allow the networks to be reconfigured—automatically—on the fly. That's a huge challenge right now, but it's critical because it would provide the flexibility needed to deal with the exigencies of war.

At one moment, you might need an enormous video bandwidth in a certain area; in the next, you might need to convey a huge amount of targeting data. Alternatively, different streams of data might need different levels of encryption.

Automatically reconfigurable software-defined networks would make all of this possible. The military advantage would be that software running on the network could use data sourced from anywhere in the world to pinpoint location, identify friends or foes, and to target hostile forces. Any authorized user in the field with a smartphone could see on a Web browser, with data from this network, the entire battlefield, no matter where it was on the planet.

We partnered recently with the U. Armed Services to demonstrate key aspects of this 5G. MIL vision. In March , Lockheed Martin's Project Hydra demonstrated bidirectional communication between the Lockheed F and F stealth fighters and a Lockheed U-2 reconnaissance plane in flight, and then down to ground artillery systems. This latest experiment, part of a series that began in , is an example of connecting systems with communications protocols that are unique to their mission requirements.

All three planes are made by Lockheed Martin, but their different chronologies and battlefield roles resulted in different custom communications links that aren't readily compatible.

Project Hydra enabled the platforms to communicate directly via an open-system gateway that translates data between native communications links and other weapons systems. Emerging technologies will fundamentally change the character and speed of war and will require an omnipresent communications backbone to manage capabilities across the entire battlefield. It was a promising outcome, but reconnaissance and fighter aircraft represent only a tiny fraction of the nodes in a future battle space.

Lockheed Martin has continued to build off Project Hydra, introducing additional platforms in the network architecture. Extending the distributed-gateway approach to all platforms can make the resulting network resilient to the loss of individual nodes by ensuring that critical data gets through without having to spend money to replace existing platform radios with a new, common radio.

Another series of projects with a software platform called HiveStar showed that a fully functional 5G network could be assembled using base stations about the size of a cereal box. What's more, those base stations could be installed on modestly sized multicopters and flown around a theater of operations—this network was literally "on the fly.

The HiveStar team carried out a series of trials this year culminating in a joint demonstration with the U. Army's Ground Vehicle Systems Center. The objective was to support a real-world Army need: using autonomous vehicles to deliver supplies in war zones.

The team started simply, setting up a 5G base station and establishing a connection to a smartphone. A white 3-D printed box housed processors for distributed-computing and communications software, called HiveStar.

The housings were mounted on unpiloted aerial vehicles for a demonstration of a fully airborne 5G network. The team then tested the compact system in an area without existing infrastructure, as might very well be true of a war zone or disaster area.

And so, in , the dishwasher was born. Actually, that's not strictly true. The first recorded evidence of a dishwasher dates back to when a crude hand-turned splashing device attached to a wooden tub, made by Joel Houghton, was given a patent.

It wasn't much cop, however, and even L A Alexander's development on this idea — adding gears to a spinning rack so that it could hold dishes, which could then be spun inside a wooden tub of water — wasn't much of an improvement.

Josephine's contraption, however, was in a different league. She built the first automatic dishwasher, a wooden wheel lying flat in a copper boiler. The wheel could be turned by hand or driven by a power source via a pully. Don't miss our next newsletter! Cricket Media Articles. Invention Activities. For Educators InvenTeam Grants.
