INDUSTRY PERSPECTIVES

brain synapse Medtronic Fighting For Minutes…While Losing Hours

We’ve all seen or heard commercials from the American Stroke Association (ASA) encouraging people who suspect they might be having a stroke to call 9-1-1 right away, because “time lost is brain lost.”. Stroke is the No. 5 cause of death in the United States, killing nearly 130,000 people a year. That’s one in every 20 deaths, according to the ASA. But even if you survive a stroke, you are not even close to being out of the woods.

  • Want Better Devices? Send Your Engineers Into The OR

    Before he was an “Outdoor Man” marketing sporting goods in the Rocky Mountains as the Last Man Standing, Tim (“The Tool Man”) Taylor did most of his work indoors — on a little show called Home Improvement. Fortunately for the often accident-prone know-it-all, he had a competent sidekick in the mild-mannered Al Borland, who often knew a better way to get things done properly.

  • Incorporating Accessibility Into Medical Device Design

    When incorporating human factors into medical device development, conducting user testing and gathering feedback from the device’s target end users is critical. To do this properly, the end user groups must be appropriately defined.

WHITE PAPERS & CASE STUDIES

  • Turning To Integrated Driver Electronics For BLDCs

    Despite advantages, brushless DC motors (BLDCs) have presented their own challenges in terms of technology, design, and capabilities. Typically, complex and bulky cabling has been required between motor and amplifier to attach discrete logic components “outside” the motor frame. With the latest advances in driver electronics that now can be integrated directly into brushless motor designs, BLDCs are evolving rapidly to become faster, smaller, more versatile, more controllable and more cost-effective.

Reasons For Turning To Slotless Technology

Brushless motors have gained greater acceptance in industry for a wider range of applications previously dominated by brush commutated products. At the same time, manufacturers have further sought to challenge conventional wisdom by improving brushless motor design. 

Brush DC Motors Turning More Advanced

Motor designs have incorporated new components in new ways to help extend motor life, and new or improved materials have been tapped to promote motor quality and output. Current and future brush commutated DC motors continue to move in highly advanced directions.

Customization To Suppress Electromagnetic Interference In DC Motors

A variety of active and passive approaches can be adopted to reduce electromagnetic interference (EMI) in systems that rely on precision motion control. The challenges are to maintain system integrity and DC motor performance without adding significant cost or weight to a subassembly.

Cartridge Brush Design For DC Motors And Gearmotors

The traditional method for mounting copper or silver graphite brushes in brush commutated DC motor and gearmotor assemblies has been to solder the brushes onto standard cantilever springs to enable the required constant contact with the commutator. However, this conventional spring design carries inherent drawbacks that can be overcome by housing the brushes within a specially designed cartridge and utilizing torsion springs to ensure desired even force over the life of a motor.

DESIGN COMPONENTS & SERVICES

Shimadzu was the first company to offer dynamic auto-alignment as a standard feature in an FTIR spectrometer in its' price range. With state-of-the-art technology, the Shimadzu dynamic alignment system continuously maintains optimal alignment during data acquisition, ensuring consistently reproducible spectra without the need for tedious mechanical adjustments.

Colder's new SRC connector is a unique small bore connector that eliminates the potential for misconnections with luer fittings. The intuitive design is simple to operate and provides a secure, leak-free connection.

Avalanche Photodiodes – Silicon and InGaAs APDs
Excelitas’ rear entry “reach-through” silicon APDs offer the best compromise in terms of cost and performance for applications requiring high speed and low noise photon detection from 400 nm up to 1100 nm. These APDs feature low noise, high quantum efficiency and high gain while maintaining reasonably low operating voltage. The active area varies from 0.5 mm to 3 mm to accommodate a large variety of applications including laser range finding, confocal microscopy, free space communication, fluorescence detection, DNA sequencing, and particle sizing.

Insert molding techniques can streamline the production of your next medical device and eliminate the need for additional secondary operations. This type of molding can result in consistency, stability, the potential for reduced size and weight, and design flexibility.

Corry Micronics' Gain Horn Antennas operate in the sub-gigahertz to over 100 GHz frequency range. These antennas can be custom manufactured for different applications, including but not limited to aerospace, military, wireless communications, and medical.
