Micro dc/dc converter

Surface-mount micro dc/dc converter measures only 0.225 x 0.165 x 0.093 inch (LWH). The converter functions with a portable device's battery to provide a distributed power source that minimizes power loss via supply voltage control of the device's RF power amplifier circuit. The micro converter has 20 W/cm3 power density with 85% efficiency that the company says, for example, can increase cell phone operational time by 39%-180 to 250 minutes. The company uses flip-chip bonding with precise high-density component mounting, and the converter has compatibility with standard tape-and-reel dispensers. The chip accepts input voltages from 3.0 to 5.5V and provides adjustable output from 0.8 to 3.0V dc at 350 mA.

Machine vision system

FiberInspect(TM) automatically detects and measures scratches, cracks, and spots on fiber cable that form during the polishing process. The machine vision system can reportedly detect fiber-end defects smaller than a single micron, even when there is poor image contrast between the defect and background. The system can also be configured to classify defects by type to help users better quantify problems during the polishing process.

Marker sensor

The STEALTH(R) Laser Sensor is designed to detect invisible marks formulated with ISOTAG S ClirCode(R) markers. This combination of a laser sensor and invisible marker performs a variety of registration-mark and product-inspection tasks. The system's usefulness is increased because ambient or UV fluorescent light from either man-made or natural materials do not affect it.

Handheld counter

The Digital Hand Tally Counter permits counts up to 99,999. The water-resistant, O-ring-sealed counter produces an audible click that signals the count when its button is pressed. A fail-safe design eliminates accidental resetting. It weighs 1 oz and is 2.5 inches x 2 inches x 0.75 inch. Contained in a shock-resistant ABS plastic case, the LCD display and counter electronics are sealed against dust, dirt, and humidity.

Scanning CMM

The Endeavor FlexScan series Scanning Coordinate Measurement Machine (CMM) features a motorized, articulating probe head that eliminates the need for clusters of special probe configurations and extensions. It is flexible and can reportedly handle an analog probe, a touch-trigger probe, or both. Users can use the CMM to combine scanning and discrete point measurement on the same part without interruption.

Digital panel meter

The Trident Digital Panel Meter is factory calibrated to accept process voltage and current inputs, 100-ohm platinum RTDs, and four types of thermocouples. Setup and programming is jumper-free, and can be completed via a four-button programming method or a computer. If multiple meters need to be programmed, a copy capability allows one meter's setup to be automatically copied to another meter. The Trident's universal power supply allows any voltage between 85 to 265V ac or 90 to 260V dc.
