Dual Hot Swap Controller

Linear Technology Corporation (Milpitas, CA) has introduced the LTC4224, a compact, low voltage Hot SwapTM controller for protecting boards and backplanes that uses two 1V to 6V voltage supplies. The LTC4224 enables safe insertion and removal of a module into a rail by limiting any in-rush currents large enough to create a glitch on the rail, which can cause other plug-in modules to malfunction. Peak fault currents are controlled in less than 1μs and an optional gate capacitor can be used to adjust the gate slew rate. The LTC4224 is suitable for optical networking, low voltage Hot Swap control, and electronic circuit breaker applications.

Specimen Tracking System

Applied Scientific Instrumentation (Eugene, OR) has introduced PhotoTrack, a system specifically designed to solve the problem of tracking a moving specimen. Combined with ASI’s closed-loop DC servo motor stages, PhotoTrack allows users to keep free moving samples in their field-of-view (FOV). PhotoTrack uses a low-light-level rapid position-sensing quadrant PMT sensor to monitor a bright reference spot on the target. It then commands an ASI automated XY stage to maintain that spot in the center of a microscope’s field-of-view.

Multimedia Kit

Moritex (Cambridge, UK) has introduced a multimedia kit for its LightScope industrial endoscopes that includes everything required to perform wide ranging portable inspection and video documentation tasks. The multimedia kit includes a high quality CCD camera, 2.5-inch TFT LCD screen, and a bracket to ensure secure mounting to the LightScope. Backed by SD flash card memory the multimedia kit enables users to capture, record, and view MP4 video clips in real time. Integral USB port and TV-out connection enable output of video clips to PCs and larger screen devices.

Ultra-Thin Silicon Solar Cells Process

IMEC (Leuven, Belgium) has developed a new method to produce ~50μm thin crystalline silicon wafers for use in solar cells. The process involves mechanically initiating and propagating a crack parallel to the surface of a Si wafer. The method makes use of industrially available tools, such as a screen printer and belt furnace, and is potentially kerf-loss free. Adding an ultra-thin wafer or foil of active silicon on top of a low-cost substrate is a solution to reducing the amount of high-grade silicon used in solar cells.

Laser Marker

Automated Laser Corporation (Fort Wayne, IN) has introduced the LSG-10 Laser Marker, the next generation of their high-speed CO2 laser markers. The LSG-10 offers a larger marking window, more choices and sizes of text including all True Type fonts, increased speed, more focal length choices, and the ability to mark many popular image formats all with considerable speed and precision at an affordable price.
