The document describes the Aurora Tigon, a new high performance computing system from Eurotech. Some key points:
- The Aurora Tigon can achieve up to 350 teraflops of performance in just 1.5 square meters using 256 CPUs and 256 accelerators.
- It uses direct liquid cooling to achieve high energy efficiency, with a target PUE of 1.05 and no need for air conditioning, resulting in up to 50% less energy usage.
- In tests, the Aurora Tigon achieved a world leading performance of 3150 million floating point operations per watt, 30% more efficient than the most efficient system on the Green500 list and 15 times more efficient than a typical
SUN Telecom’s PLC splitters divide a single/dual optical input(s) into multiple optical outputs uniformly,
and offer superior optical performance, high stability and high reliability to meet various application
requirements. Our standard PLC Splitter modules include “Cassette” and “Rack Mount” two types. We
also provide customized products.
The KBMK Series of Digital Adjustable Frequency Drives consist of two inverter models rated for 1/8 to 1 horsepower motors. These drives are housed in NEMA 1 / IP 50 aluminum enclosures. The KBMK-24DF contains a built-in CE approved AC Line Class “A” Industrial Standard RFI (EMI) Filter.
Options: IODA Input/Output Multi-Function Module and On/Off AC Line Switch.
A Plasma Tweeter is an audio device which uses a pair of electrodes as a source of sound. It has a clear reproduction and Omni directional radiation pattern. A plasma tweeter has a better frequency response than a conventional speaker and does not involve any moving part (diaphragm) and thus has less reverberation and no wear and tear. Plasma tweeters invented earlier were very expensive. This paper presents a plasma audio system which is making the regular audio system more efficient because of the use of the latest plasma tweeter. Here the objective is to create a low cost and more efficient version of the most speakers invented till now with the complete audio system.

CPU Subsystem Total Power Consumption: Understanding the Factors and Selectin...CAST, Inc.
Power consumption figures for a processor core only tell part of the energy usage story for a CPU subsystem.
Smart IP choices regarding performance, instruction set architecture, required memory operations and size, and other factors can also significantly reduce the real-world total power required for such subsystems. Learn how to better assess these factors through practical comparisons with processor cores supporting the BA2 ISA, which offer both extreme code density and excellent performance (see http://www.cast-inc.com/ba22).

The FlowHUB is ideal for condition monitoring, test
stands and closed loop control applications both for
fluid power and lubrication systems. The FlowHUB can
measure and display flow and temperature readings as
well as switch and transmit flow values. This enables a
system designer to trigger alarms, shutoffs and transmit
real-time values to a PLC using just one component,
instead of up to six which might have been required
conventionally. This represents a significant cost saving
in terms of reduced complexity of wiring and far fewer
components.
It is available in five flow ranges from 0.25 to 100 US
gpm (1 to 360 lpm) and in two pressure ranges 3,000
and 6,000 psi (210 and 420 bar). The FlowHUB is
available in three versions - ‘Switch’, ‘Transmitter’ and
‘Ultimate’, all three versions have built in temperature
measurement and a large bright digital display.
The \'Switch\' version provides two configurable switched
outputs; the trigger flow rate, time delay, sense
(above/below) and normal mode (normally closed /
normally open) can all be freely configured. Each
switch is independent and can switch up to 500 mA.
The \'Transmitter\' version provides a conditioned analog
output either 0 to 5 Volts or 4 to 20 mA - full scale is
configurable to any maximum flow. The \'Ultimate\'
version has both the switches and transmitter and the
highest pressure rating of 6,000 psi (420 bar) as well as
an enhanced response time of 50 ms.
Other configurations are available on request.
