ZScanner 700

Z Corporation, Burlington, MA, has introduced the ZScanner 700, a handheld, self-positioning 3D scanner that can digitize 3D surfaces in real time. The scanner is part-referenced, orienting itself to the target object, rather than to an external device. This eliminates the need for fixed-position tripods, mechanical arms, or other positioning devices that must be within the line of sight of the target surface. The user also can move the target object during scanning, and displays a real-time, on-screen image of the surface being scanned. To scan, the user holds the scanner and "paints" the object with a projected laser crosshair. The surface is recorded by the scanner's dual cameras, and ZScan software, included with the scanner, generates a polygon mesh of the surface on the computer screen in real time. The scanner captures data in one continuous scan. The software automatically produces an .stl file for import into a 3D CAD package, or output to a 3D printer. The system is accurate to within ±0.05 mm, and detects changes in surface height down to 0.1 mm. For Free Info Visit http://info.hotims.com/10952-120

13-bit magnetic sensor

Renishaw, Hoffman Estates, IL, has introduced a 13-bit magnetic sensor for rotary and angular positioning control. Providing 8,192 counts per revolution, the sensors are available in chip, chip-on-board, and ready-to-mount packaged versions. The solid-state, non-contact design features an integrated circuit chip that senses the position of a separate two-pole permanent magnet. Suited for difficult environmental requirements, the sensors provide -40°C to 125°C operational temperature range, and shock and vibration resistance. Friction-less, low-inertia operation enables 0.3° positioning accuracy at speeds to 30,000 rpm. They are available in models providing absolute, incremental, analog, or digital outputs, as well as simultaneous SSI and incremental output. Chip and chip-on-board models allow the sensors to be integrated into machinery and equipment designs. Packaged versions enclose the chip and electronics in metal cases. Enclosed units are used in rugged applications and environments; fully encapsulated versions are waterproof.

p1411A RF vector signal generator

PrecisionWave Corp., Colorado Springs, CO, has introduced the p1411A RF vector signal generator that includes a spectrum analyzer display and an internal IQ waveform generator. It is available in both benchtop and ATE configurations. User-created IQ waveforms can generate other signal types, specify data content, or create worst-case signal scenarios for development and test of ICs, sub-assemblies, or completed products. The display continuously shows the instrument's output, and can be used to preview waveforms prior to selecting them for output. The 7" TFT display includes a touch panel for instrument control without an external mouse, keyboard, or stylus - all of which can be connected if required. The instrument features LAN programming, and may be controlled and monitored from Web applications. It includes a low-phase-noise 10-MHz internal frequency reference, and can accept an external 10-MHz reference signal for synchronization with other devices and test equipment.

How Much Financing Does Your Growing Company Need?

How much money will your growing company need? The answer is, you want enough investment to grow the company to its potential, yet do not want to over-fund, giving up too much equity. You cannot raise funds without a reasonable estimate of what you need.

Building the Financials to Get Investors Interested

In our last article, we planned out the business chronologically; that is, what we expected to happen and when we thought it would happen. Now, we need to assign costs to the steps in that series of events and roll it up into a standard financial picture that investors, members of your board, employees, and others will understand.

NASA Studies Benefits of Exercise for Astronauts and Public

The 20-G Centrifuge facility at NASA Ames has a radius of 29 feet and is human-rated to 12.5 G. (NASA)NASA's Ames Research Center in California has teamed with the University of Kentucky in Lexington and Vanderbilt University in Nashville, TN, to study ways to reduce adverse effects of space travel on an astronaut’s health. The study is being done on the 20-G Centrifuge at Ames, a machine that creates artificial gravity forces by spinning, and that can simulate up to 20 times the normal forces of gravity experienced on Earth.
