The new network LED Dimmer from Opto 22 uses pulse width modulation technology (PWM) to control brightness from 0-100 percent for 9-30 to control VDC constant voltage LED lighting assemblies such as lamps, bulbs, strips, ropes and bars. It can also be used for other resistive-type loads. (Source: Opto 22)
Cabe, Very surprising that serial communications wouldn't be a topic that everyone would be exposed to. But I guess it is simple enough that young engineers can get up-to-speed on their own if they need to
In a lot of vehicles today, the interior lights dim as you prepare to drive, or when leave the vehicle and close the door. I do wonder if LEDs have been able to do that up tp now. This technology would be important for those applications, I would think.
Al, this is an interesting approach, and as you point out it is flexible and extensible. One thing it does bring to light (pun intended) is that controlling LEDs is much more complex than the systems they replace. On the other hand, with the electronics we have available now, it is not a problem to develop and integrate systems such as this.
United Launch Alliance will fly 3D-printed flight hardeware parts on its rockets starting next year with the Atlas V. The company's Vulcan next-gen launch vehicle will have more than 100 production parts made with 3D printing. The main driver? Parts consolidation and 57% lower production costs.
The new small-form-factor EZ-BLE PRoC (Programmable Radio on Chip) module is a derivative of the existing PRoC BLE Programmable Radio-on-Chip solution. The EZ-BLE PRoC module integrates the programmability and ARM Cortex-M0 core of the PRoC BLE, two crystals, an onboard chip antenna, a metal shield, and passive components.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
