DRX9000 Engineering Design - Part 2

CurtisEllzey — Wed, 01 Jul 2009 14:00:00 GMT
Scot Johnson from Axiom Worldwide continues his walkthrough of the DRX9000. He discusses the use of X-1R lubricants, a Certified Space Technology. Applied to critical DRX9000 subsystems, X-1R lubricants help reduce friction and provide the desired smooth operation while extending bearing and gear life. Scot also talks about Axiom's team of engineers and programmers that have combined cutting edge technology and science, allowing them to offer physicians and their patients an effective alternative to surgery.

DRX9000 Engineering Design - Part 1

CurtisEllzey — Tue, 30 Jun 2009 14:00:00 GMT
Axiom Worldwide's Director of Engineering Research and Development, Scot Johnson, takes us on a walkthrough of the DRX9000 True Non-Surgical Spinal Decompression System. The vast majority of components are designed and fabricated at their headquarters in Tampa, Florida. Highlights include a closed-loop feedback system within a closed-loop feedback system, referred to as nested closed-loop feedback. A servo-amplifier receives corrective force commands from the treatment computer 13 x per second. The servo-motor itself contains very accurate measurement devices that measure position, speed, and power consumption. The servo-amplifier monitors these variables, correcting the actions of the servo-motor 4,000 x per second. For more information, go to: Axiom Worldwide.

DRX9000 Spinal Decompression System

CurtisEllzey — Mon, 29 Jun 2009 14:00:00 GMT
The DRX9000 True Non-Surgical Spinal Decompression System is designed to provide pain relief for compressive and degenerative injuries of the spine. As it relates to Axiom Worldwide’s DRX technology, the theory behind non-surgical spinal decompression is a process whereby forces are applied to the spine in a manner that maximizes spinal elongation. Since its inception, the DRX9000 has shown promising anecdotal results in treating back pain caused by herniated discs, degenerative disc disease, sciatica, and facet syndrome. For more information, go to: Axiom Worldwide.

Dimension Icon AFM Walkthrough

CurtisEllzey — Tue, 16 Jun 2009 14:00:00 GMT
Veeco's John Thornton takes us through the operation of their Dimension Icon Atomic Force Microscope to scan the surface of a gallium nitride wafer. Many of the Dimension Icon AFM’s new features are engineered specifically to enhance technical performance while simultaneously increasing usability and productivity for both new and expert AFM users. The system utilizes a revolutionary XYZ closed-loop head that scans at high-speed rates while delivering extremely low drift and low noise. These features combine to drastically cut stabilization times, allowing the system to acquire artifact-free data in much less time than is possible with any competing AFM on the market. Also watch this episode: Dimension Icon Atomic Force Microscope. For more information, go to: Veeco.

Dimension Icon Atomic Force Microscope

CurtisEllzey — Mon, 15 Jun 2009 14:00:00 GMT
Veeco's Dimension Icon Atomic Force Microscope (AFM) brings new levels of performance, functionality, and AFM accessibility to nanoscale researchers in science and industry. Incorporating the latest evolution of Veeco’s industry-leading tip-scanning AFM technology, the Icon’s temperature-compensating position sensors render noise levels in the sub-angstroms range for the Z-axis, and angstroms in X-Y. This is extraordinary performance in a large-sample, 90-micron scan range system, surpassing the noise performance of most open-loop, high-resolution AFMs. Also watch this episode: Dimension Icon AFM Walkthrough. For more information, go to: Veeco.

Micromuscle

CurtisEllzey — Thu, 30 Apr 2009 14:00:00 GMT
Electroactive polymers (EAP) are an emerging class of materials with many new revolutionary properties. One of the main advantages of electroactive polymers is the possibility to electrically control and fine-tune their behavior and properties. Using Micromuscle EAP technology, a wide variety of small moving components can be constructed. The possibility to create moving structures and exert force enables new functionality for medical devices and other life science products. For more information, go to: Micromuscle.

Dermasol Thermoplastic Elastomer

CurtisEllzey — Tue, 24 Feb 2009 15:00:00 GMT
Dermasol is a new thermoplastic elastomer that feels remarkably like real human flesh. It can be made in any color (including clear), any shape and almost any durometer (hardness). It is especially useful for simulating tissue in organs and body structures for practicing operations and medical training. For over 20 years, California Medical Innovations has been formulating and compounding natural rubber latex, plastisols, and thermoplastic elastomers.

Inside HERCULES - Part 2

CurtisEllzey — Thu, 19 Feb 2009 15:00:00 GMT
Engineering TV concludes our inside look at the University of Michigan's HERCULES Petawatt laser. Dr. Victor Yanovsky elaborates on their amplification process, the compression of the output pulse using a 4-grating compressor, and the interaction chamber where the super-intense beam is focused by a parabolic mirror. Through projects like HERCULES, the goal of the NSF funded Physics Frontier Center FOCUS is to explore the ultra-relativistic intensity regime of laser-matter interaction, and ultimately reach 1023 W/cm2, by focusing about 15 J at 30 fsec (500 TW) to a diffraction limited focal spot of about 1 micron. Also watch these episodes: HERCULES Petawatt Laser and Inside HERCULES - Part 1. For more information, go to: Center for Ultrafast Optical Science.

Inside HERCULES - Part 1

CurtisEllzey — Wed, 18 Feb 2009 15:00:00 GMT
Dr. Victor Yanovsky takes us on an in-depth walk-through of the HERCULES Petawatt laser, starting with the short pulse oscillator on through the stretching of the energy pulse using their modified mirror-in-grating design. Ultrashort laser pulses are the shortest controlled bursts of energy ever developed. Optical pulses of a few femtoseconds (10-15 s) duration can be used to probe the fastest events in atomic, molecular, biochemical, and solid state systems. When amplified to even modest energies, such short pulses can achieve the highest peak powers. Also watch these episodes: HERCULES Petawatt Laser and Inside HERCULES - Part 2.

HERCULES Petawatt Laser

CurtisEllzey — Tue, 17 Feb 2009 15:00:00 GMT
Engineering TV visited The Center for Ultrafast Optical Science at the University of Michigan to take a closer look at HERCULES, a high-field petawatt class laser. The beam measures 20 billion trillion watts per square centimeter, contains 300 terawatts of power (300 times the capacity of the entire U.S. electricity grid), and is capable of producing this intense beam once every 10 seconds. Applications include optical communications at the terabit level, studies involving the behavior of electrons in quantum structures, and biomedical fields such as eye surgery , subcellular "nanomachining", and in vivo sensing (for example in vivo cytometry of circulating cancer cells). The National Science Foundation through the Physics Frontier Center FOCUS supports the development and construction of this laser. Also watch these episodes: Inside HERCULES - Part 1 and Inside HERCULES - Part 2. For more information, go to: Center for Ultrafast Optical Science.

Huggable Robot Interface

CurtisEllzey — Tue, 16 Dec 2008 15:00:00 GMT
The Huggable companion robot from MIT is designed to be much more than a fun interactive robotic companion. It is designed to function as a team member that is an essential member of a triadic interaction. Therefore, the Huggable is not designed to replace any particular person in a social network, but rather to enhance that human social network. The MIT Media Lab has developed several interfaces for the Huggable: a web interface to enable a remote operator (e.g., educator, grandparent, friend, etc.) to view the state of robot and evoke its behaviors, “stale panorama” interface, and a sympathetic interface that consists of a waldo-like device which maps to the Huggable robot’s body and joint angles. Also watch this episode: MIT's Huggable Robotic Companion. For more info, go to: MIT Personal Robots Group.
