Coalescence Cascade

Came across some videos of 2,500 and 10,000 fps films of water droplets interacting with the larger body of water. They preform the coalescence cascade which the first video explains pretty well.

Biochip Implant

Tim Cannon, a biohacker, is impanting a sensory chip in his arm in hopes of advances similar tech and implants in the future. The chip called Circadia can read biomedical data and transmit it to the Internet via bluetooth. “Instead of taking snapshots of your health by visiting a doctor, you can aggregate weeks or months of medical data that you can store for your personal viewing.” – Grindhouse Wetware : http://www.grindhousewetware.com/index.html

Robotic/Prosthetic Arm

Proto 2 and The DEKA Arm

http://www.oandp.com/articles/2013-02_01.asp

Two forms of robotic arms are now being developed. Those for people who are paralized and those for amputees. The paralized version makes use of electocortographical (ECoG) array implants. These pick up signals the patients send out when they think to move their prosthetic forward, back side to side, to rotate it or to grasp, etc. This method can take up to thrity days of test/programming to produce desired movements. Another patient who had two array impants that barely penetrated the motor cortex was able to obtain three degrees of freedom in three days.

The other form of arm is one in which an amputee’s severed nerves are connected to the arm. Using the nerves from  the bicep, the brachioradialus, and one of the heads of the triceps the robotic arm picks up on the same nerve firing/signals that the amputee’s brain still sends out when thinking about moving thier arm. Patients with these arms have been able to achieve 12 degrees of freedom. The arms have the possibility of achieving 26 degrees of movement while the human arm has 30 degrees of movement. The DEKA arm seems to be the most advanced of the arms and closest to becoming commercially accesible. Some of the arms have the ability to provide “feeling/touch” feedback to the patients.

Whipple Shielding

In the upper atmosphere in which the International Space Station resides a serious danger is the threat of impact from micro-orbital debris. The ISS itself travels at 7 km/s around the Earth meaning that impacts can come from debris traveling at 14 km/s if traveling in an opposite orbit. At these speed objects as small as 7 grams can cause significant damage. To reduce these speeds and subsequent damage the ISS borrows and developed a system used by Tanks in World War II. This system is called Whipple Shielding and is a system of dispersing energy. This shielding consists of a thin outer sheet of aluminum which absorbs impact of smaller projectiles and in the process shatters them. This sheet is held apart from the International Space Station by some distance which allows the even smaller particles, now slowed and broken up, to disperse damage to a larger area of the hull. For larger objects the ISS must perform maneuvers.
