ELECTRONICS: Vectron International’sPX-420 crystal oscillator is able to withstand continuous operating temperatures of up to 250C, the product is ideal for harsh environment applications, including oil and gas downhole operations.With the PX-420, Vectron successfully combines its advanced quartz resonator design for outstanding frequency stability with silicon on insulator (SOI) technology to meet the high-reliability requirements demanded by these harsh environment applications. For the first time, design engineers have a solution for applications requiring continuous, high-reliability operation at temperatures ranging from -55 to 250C. Vectron’s PX-420 crystal oscillator offers the widest temperature range and best frequency tolerance currently available for frequency control oscillators in the market. The unique compliant quartz resonator mounting scheme also provides high shock and vibration resistance.
Specific features of the PX-420 include:
Ultra high continuous operating temperature (-55 to 250C)
Special doubly rotated quartz resonator and electrode metallization for outstanding frequency stability
Silicon on insulator (SOI) technology for high reliability requirement in harsh environments
± 100ppm frequency stability over the entire operating temperature range
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
A recent example of a major CAE revamp is MSC Apex, released last month by MSC Software Corp. In a discussion with Design News, MSC executives noted that its next-generation platform is designed to substantially reduce CAE modeling and process time, “in some cases from weeks down to hours.”
The Thames Deckway would run for eight miles close to the river’s edge, rising and falling slightly with the tidal cycle. It will generate its own energy from a series of devices that will line the pathway and use a combination of sources to make the path self-sustaining.
