Wireless, handheld device for ground control of X-47B unmanned aircraft tested The first shore-based trials of the Control Display Unit (CDU) that wirelessly controls the X-47B on the ground (Photo: Northrop Grumman) Image Gallery (2 images) While impressive, unmanned flight is just one of the capabilities required of the Northrop Grumman-built X-47B Unmanned Combat Air System (UCAS) if it is to enter service with the U.S. Navy. Prior to and after any flights, the aircraft also needs to be safely maneuvered around the crowded deck of an aircraft carrier. In its first shore-based trials carried out earlier this month at Naval Air Station Patuxent River, Maryland, the handheld device, called a Control Display Unit (CDU), was used to control the X-47B’s engine thrust to roll the aircraft forward, brake and stop, and use its nose wheel steering to execute the tight, precision turns required to maneuver the aircraft into a catapult or out of the landing area following a landing.

Knocking Down a Door Alright, let’s get this out of the way first: kicking down a door is not the best option for opening a locked door. It will damage the door and cost you lots of money to fix it. It is better to call a locksmith, pick the lock, or attempt to crawl in a window. But let’s say it’s an emergency. You’re in a burning house and you need to escape and the door is on fire. How to break down a door If you have watched enough movies, your next move is a no brainer….run at the door shoulder first, right? Check to see which way the door opens by checking the hinges. Kick to the side of where the lock is mounted (near the keyhole). Using a front kick, drive the heel of your foot into the door. The wood should begin to splinter. Avoid jump kicks.

Nuclear Weapons - basic technology concepts [UNC] A few words about nuclear weapons technology.. Fission weapons Nuclear weapons exploit two principle physical, or more specifically nuclear, properties of certain substances: fission and fusion. Fission is possible in a number of heavy elements, but in weapons it is principally confined to what is termed slow neutron fission in just two particular isotopes: 235U and 239Pu. Typical appearance of a thermonuclear weapon detonation -- from many miles away. *Special techniques were required to record the fleeting moments of a weapon's initial detonation.
Shaking Hands: How to Give a Strong Handshake I’m in law school right now and as a future attorney, I’ll be shaking lots of hands: clients, potential clients, other attorneys, and judges.

Demon core Manufacturing and early history[edit] The two physicists Harry Daghlian (center left) and Louis Slotin (center right) during the Trinity Test The next bomb of the implosion type had been scheduled to be ready for delivery on the target on the first good weather after August 24th, 1945. Marshall added an annotation, "It is not to be released on Japan without express authority from the President", as President Harry S. First incident[edit] On August 21, 1945, the plutonium core produced a burst of neutron radiation that led to physicist Harry Daghlian's death. Second incident[edit] A re-creation of the 1946 experiment. On May 21, 1946,[11] physicist Louis Slotin and seven other Los Alamos personnel were in a Los Alamos laboratory conducting another experiment to verify the exact point at which a subcritical mass (core) of fissile material could be made critical by the positioning of neutron reflectors.

How To Win a Street Fight Let’s say you’re out with your buddies (or maybe a lovely young lady) having a good time, when all of a sudden some jackass shoves you. You didn’t do anything to instigate the guy, but it doesn’t matter. There is a special breed of males, that when inebriated, start fights with random people. This breed, when found in their wild habitat, are often accompanied by their similarly boneheaded buddies. Or perhaps you and your posse end up in a rumble with the Socs because one of your buddies killed a Soc while trying to save Ponyboy from being drowned by a douche bag Soc. What can you do to prepare for a street brawl and protect yourself in this type of situation? 1. 2. 3. 4. 5. Knee to the groin. 6. A punch to the head. 7. 8.

Handcuffs Of The Future Administer Shocks And Drugs To The Detained A patent for next-generation handcuffs offers a future in which the detained can be zapped directly from their restraints, and even injected with a medication, sedative, irritant, paralytic, or other fine substance. The patent is called “Apparatus and System For Augmented Detainee Restraint” and is the brainchild of Scottsdale Inventions.The augmentations it offers are truly quite something. The handcuffs are “configured to administer electrical shocks when certain predetermined conditions occur.” These shocks might be “activated by internal control systems or by external controllers that transmit activation signals to the restraining device.”These handcuffs might also be used to inject the detained with a substance in the form of “a liquid, a gas, a dye, an irritant, a medication, a sedative, a chemical restraint, a paralytic, a medication prescribed to the detainee, and combinations thereof.” Yes, you really did read the word “paralytic.”
How to Make Introductions Have you ever been at a party with a guy who runs into somebody he knows and starts yammering away while you stand there awkwardly, holding your drink? Man, I hate when that happens. You’re left in social limbo. I usually have to just take things into my own hands and introduce myself, which is fine, but the exchange would have been much smoother had my friend introduced me to his buddies. Being introduced invites you into the conversation and makes you feel like part of the group, which is why making an introduction shows your respect for your guest. With our more casual culture, the art of the gentlemanly introduction has disappeared, but we’re here to help bring it back. Making introductions used to be a much more formal affair, with bowing, scraping, and a lot of rules, but nowadays just remembering to make them sets you apart from the cads out there. The Big Rule The overarching principle when making introductions is deference and respect. Business Introductions Social Introductions
Rheinmetall's 50kW high-energy laser weapon successfully passes tests Practical high-energy laser weapons came a step closer to reality in November as Rheinmetall tested its new 50 kW high-energy weapon laser demonstrator. The series of exercises took place at the German-based group’s Ochsenboden Proving Ground in Switzerland. There the 50 kW laser weapon was tested against a series of targets to show the improvements over last year’s 10 kW version. Designed for air defense, asymmetric warfare and Counter Rocket, Artillery, Mortar (C-RAM) operations, the Rheinmetall laser isn't a single weapon, but two laser modules mounted on Oerlikon Revolver Gun air defense turrets with additional modules for the power supply. The lasers are combined using Rheinmetall's Beam Superimposing Technology (BST) to focus a 30 kW and a 20 kW laser on the same spot. The tests set the laser against three different targets.

How to Criticize (and Take Criticism) Dealing with criticism is a skill every well-adjusted man should possess. We give and take criticism among our co-workers, our friends, and our family. Criticism is an important part of our personal self improvement, for it is other people who can point out mistakes and shortcomings that we can’t see because we lack objectivity. Unfortunately, many young men today don’t know how to offer and accept criticism like a man. Because we all face situations every day that require us to give or take criticism, we provide the following guidelines on how to make the process more constructive. How to Give Effective Criticism Go in cool, calm, and collected. Be specific. Criticize the action, not the person. Be a diplomat. This can help take the sharp edge off of criticism. Make specific suggestions for improvement. Personalize your approach. Point out positives. Follow up. How to Take Criticism Consider the source. Shut your trap and listen. Don’t take it personally. Ask clarifying questions.
