Elma Bustronic Corp.'s 6U VPX Load Board in a conduction-cooled
format is designed per the IEEE standard 1101.2 mechanical
conduction-cooled VPX load board helps confirm the chassis meets the VITA
46/48/65 power specifications for VPX and aids in locating hot spots within the
enclosure. It helps test a system's cooling
capabilities by applying the load to the power supply for verification and
creating the necessary heat to confirm chassis cooling. The board features external voltage monitoring, load
stepping, and GO-NO-GO indicator LEDs.
The conduction-cooled load card
has a microcontroller-based stepped load control to 100W maximum. The
voltage rotary switch has settings for 3.3, 5, 12V, +12V_Aux, - 12 /
48V, and Sys Reset. The set load power levels are saved in EEPROM. Bustronic
also offers VPX load boards in a 3U form factor and 6U air cooled formats.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Microchip recently released the 3D TouchPad, the first USB PC Peripheral device that couples 2D multi-touch input with 3D air gesture technology. The company seeks the help of developers to further enhance the capabilities of the technology.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
