High-Performance Data Acquisition on USB

A common belief among engineers is that in order to get the best performance, a PC-based data acquisition module must plug into the PCI bus. Properly implemented, however, a data acquisition module can use the PC’s USB port to pump data into a PC as fast as PCI-based cards. The keys to achieving this performance are a hardware USB interface on the module, and optimized driver software for the host system.

Product of the Month: July 2015

ZF Electronics Corp., Pleasant Prairie, WI, announced CHERRY energy-harvesting products that include an energy harvesting generator, as well as a snap-action micro-switch and rocker switch. The energy-harvesting generator is able to generate its own power, store the power in a chip, and transmit a signal via RF technology without the use of wires or batteries. The generator can be housed in a standard CHERRY switch product or a custom assembly. The AFIS wireless snap switch and momentary rocker switch provide data transfer via RF technology, eliminating the need for complex wire assemblies, and enabling use in inaccessible locations. The required energy is generated by mechanical actuation of the switch, eliminating the need for batteries. Flexible pairing allows operation of several switches with one receiver and vice-versa, and the switch “Unique ID” provides clear identification while operating several switches at once.

NASA Releases Global Climate Change Projections

NASA has released data showing how temperature and rainfall patterns worldwide may change through the year 2100 because of growing concentrations of greenhouse gases in Earth’s atmosphere. The data shows projected changes worldwide on a regional level in response to different scenarios of increasing carbon dioxide simulated by 21 climate models.

Intelligent Back Light

EVT (Karlsruhe, Germany) has introduced a new industrial back light in its BrainLight smart illumination series. The LEDs of the intelligent back light can illuminate in the colors red, green, blue and white. There is a diffusor plate in front of the LEDs so that the light spreads evenly over the object. All together there are 48 full-color LEDs arranged in a tight grid. The BrainLight QC is 30 x 40 mm in size and has an input voltage of +24V. It is modularly expansible, meaning LED rows can be added, depending on application. The customer can choose any of the four available colors and the LEDs can be switched on row by row. Light sequences can be programmed and played successively. To learn more, click here.
