The Evolution of Storage

The embedded computing industry is being inundated with changes to storage products driven by technological advancements, market forces and environmental concerns. The precipitous drop in solid-state flash drive (SSD) prices has enabled designers, previously turned off by the cost, to now consider solid state as an option over rotating hard disk drives (HDD). With that decision comes a serious list of performance benefits, including improvements in durability and security, which SSDs have over HDDs.

Designing Converged Optical Ethernet Networks

Transport networks have witnessed two significant trends over the past half-decade or so. The first has been an explosion in the bandwidth these networks can support and the distances over which they can support it. This is due to the advent of cost-effective wavelength division multiplexing (WDM) and dense-WDM (DWDM), as well as a slew of technologies that extend transmission range, such as sophisticated optical amplifiers. The second has been the need to support a variety of traffic types (voice, video, data) and services: virtual private networks (VPNs), high-speed Internet (HSI), video-on-demand (VoD) and videoconferencing, and IPTV, to name a few. This is due to the need to simplify the network by collapsing intermediate layers and protocol stacks, thus reducing interface and node counts (and, hence, cost) in the carrier network. Thus, transport networks have migrated from being primarily voice-dominated to multi-service supporting infrastructures.

Electrostatic Detection System Prevents Injuries and Damage During Spacecraft Assembly

Remote Voltage Sensor Quasar Federal Systems San Diego, CA 858-228-3386 www.quasarusa.com Electrostatic charges impact the safety of both workers and spacecraft, and have been recognized as one of the main problems at the NASA spacecraft assembly facilities. Prevention currently depends on time-consuming, handheld electric-field devices scanning each individual worker’s clothing. Quasar Federal Systems has developed a new electrostatic detection system with support from NASA and the University of California Berkeley’s Space Science Laboratory.
