Fibre Channel All-Flash Arrays

AccelStor (Taipei, Taiwan) announced the new NeoSapphire 3605 and NeoSapphire 3611, a pair of dedicated all-flash arrays with dual-port 16G Fibre Channel interfaces and sustained 360K IOPS for 4KB random writes. NeoSapphire 3605 offers 5TB usable capacity while NeoSapphire 3611 provides 11TB in a very compact 1U rack-mount form factor. The low latency and high reliability of Fibre Channel makes these new arrays ideal for demanding, time-critical applications including banking, finance, and media production. Reliability is further enhanced by hot-swappable drives and redundant power supplies.

Teaching Computers to Understand Human Languages

Researchers at the University of Liverpool have developed a set of algorithms that will help teach computers to process and understand human languages.

While mastering natural language is easy for humans, it is something that computers have not yet been able to achieve. Humans understand language through a variety of ways – for example this might be through looking up words in a dictionary, or by associating it with words in the same sentence in a meaningful way. The algorithms will enable a computer to act in much the same way as a human would it encounters an unknown word. When the computer encounters a word it doesn’t recognize or understand, the algorithms mean it will look up the word in a dictionary (such as the WordNet), and try to guess what other words should appear with this unknown word in the text.

High-Efficiency Power Amplifier Could Bring 5G Cell Phones

A new highly efficient power amplifier for electronics could help make possible next-generation cell phones, low-cost collision-avoidance radar for cars and lightweight microsatellites for communications. Fifth-generation, or 5G, mobile devices expected around 2019 will require improved power amplifiers operating at very high frequencies. The new phones will be designed to download and transmit data and videos faster than today's phones, provide better coverage, consume less power and meet the needs of an emerging "Internet of things" in which everyday objects have network connectivity, allowing them to send and receive data.

Integrated Circuit for Radio Astronomy Correlators Supporting Large Arrays of Antennas

NASA’s Jet Propulsion Laboratory, Pasadena, California

Radio telescopes that employ arrays of many antennas are in operation, and ever-larger ones are being designed and proposed. Signals from the antennas are combined by cross-correlation. While the cost of most components of the telescope is proportional to the number of antennas, N, the cost and power consumption of cross-correlation are proportional to N2, and dominate at sufficiently large N. As radio telescopes get larger, there is a need to provide digital-signal-processing electronics that are smaller and less power-hungry than would be implied by the extrapolation of existing designs.

Fabrication of Silicon-Leg Isolated Bi-Cr Thermopiles

Goddard Space Flight Center, Greenbelt, Maryland

The objective of this innovation was to develop a methodology of fabricating thermopile detectors using standard semiconductor fabrication techniques. The goal was to develop a fabrication process that minimized the roughening of the Si legs during patterning of the metallic couples, and to enable delineation of the Si legs without the use of highly toxic or carcinogenic chemicals. Another key requirement was at least 50% optical absorbance across the spectral band.

Current Source Logic Gate

John H. Glenn Research Center, Cleveland, Ohio

High-temperature electronic integrated circuits have been demonstrated in silicon carbide (SiC) depletion mode MESFETs. This process is only capable of producing depletion mode n-channel MESFET transistors. With only this type of transistor, designing a logic gate is a challenge. A previous logic gate design that can be constructed in the current process has performed well. This invention improves upon the previous design by increasing output voltage range and decreasing the physical layout size of a logic gate. This logic gate circuit consists of depletion mode MESFET/JFET transistors and resistors that can be constructed with SiC depletion mode n-channel MESFETs.
