D-Wave Systems, Inc. is a quantum computing company, based in Burnaby, British Columbia, Canada. On May 11, 2011, D-Wave Systems announced D-Wave One, described as "the world's first commercially available quantum computer," operating on a 128-qubit chipset using quantum annealing to solve optimization problems. In May 2013 it was announced that a collaboration between NASA, Google and the Universities Space Research Association launched a Quantum Artificial Intelligence Lab based on the D-Wave Two 512-qubit quantum computer that would be used for research into machine learning, among other fields of study.The D-Wave One was built on early prototypes such as D-Wave's Orion Quantum Computer.The prototype was a 16-qubit quantum annealing processor, demonstrated on February 13, 2007 at the Computer History Museum in Mountain View, California. D-Wave demonstrated what they claimed to be a 28-qubit quantum annealing processor on November 12, 2007. The chip was fabricated at the NASA Jet Propulsion Laboratory microdevices lab in Pasadena, California. Wikipedia.

Pressure Wave Systems GmbH has developed a dry compressor for GM and pulse tube cryocoolers. The concept is based on hydraulically driven metal bellows in which the Helium working gas is compressed. The system is operated in the region of 1 kW of electrical input power and has been successfully tested with a SHI RDK-101D GM cryocooler cold head. Set-up, performance and reliability of the compressor system will be discussed. Source

A compressor device that periodically supplies compressed working gas to a cooling device loses less of the gas by not using rotary valves. The compressor device includes a compressor cylinder, a compensation container and a drive device with an hydraulic cylinder. The compressor cylinder includes a compressor element, such as a piston or membrane, that divides the compressor cylinder into first and second volumes. The first volume contains the gas that is compressed by the compressor element. The hydraulic cylinder has a piston that is coupled to the compressor element. The compensation container contains compensation fluid and is directly connected to the second volume. The compensation container is also connected to the first volume by a gas line with a non-return valve that opens in the direction of the first volume. The drive device allows the compressed gas to be provided at a frequency required for Gifford-McMahon and pulse-tube coolers.

At NEEL we have developed an absolute novelty on a world scale: UOZ-1 animal deterring system that successfully prevents the animal-train collisions. The device exploits an animal natural sensitivity to sound and just before a train approach, at the time of the danger, a series of sounds stimulates animal instinct and enforces their life defensive reflex reaction in the form of escape. Our UOZ-1 animal deterring devise has been created in response to the particular need of preventing collisions of wild animals with trains in areas where the migration routes of animals cross the railway lines. The primary objective of the SafeTrain Project is to pilot and test in real environment the autonomous system for the automatic train detection that will be integrated with our UOZ-2 animal deterring device. The new train location system will be based on an intelligent mechanism of listening for an approaching train commercially known as an Indian ear. Our goal is to incorporate it into the animal deterring system in order to make it independent from the currently used rail signalling system. This will not only reduce the complexity of the whole system but also will reduce the investment and maintenance costs down to 60% of the todays costs. The secondary, but not less important goal is the development of green powering system for UOZ-2 utilising renewable energy sources to make the system energetically self-sustained. This will be of particular importance in areas where the rail track has not been electrified and thus with limited access to grid power. Our acoustic method for train-animal collisions prevention is an excellent solution that allows preservation of ecological corridors and animal migration routes and significantly reduces the safety and business risk of rail carriers. It overcomes all limitations of the state-of the-art solutions available on the market, and looking at Europe only, opens the way to the market worth of nearly 125m.

Device identification scoring systems and methods may be provided that can increase the reliability and security of communications between devices and service providers. Users may select and configure additional identification factors that are unique and convenient for them. These factors, along with additional environmental variables, feed into a trust score computation that weights the trustworthiness of the device context requesting communication with a service provider. Service providers rely on the trust score rather than enforce a specific identification routine themselves. A combination of identification factors selected by the user can be aggregated together to produce a trust score high enough to gain access to a given online service provider. A threshold of identification risk may be required to access a service or account provided by the online service provider.

A compressor device that periodically supplies compressed working gas to a cooling device loses less gas by not using a rotary valve. The compressor device includes a compressor chamber, a working gas connection, a working liquid connection, a pump, a compensation container and a membrane that is airtight and liquid-tight. The membrane divides the compressor chamber into a first volume containing a working gas and a second volume containing a working liquid. The working gas connection is coupled to the first volume, and the working liquid connection is coupled to the second volume. The pump periodically pumps the working liquid through the working liquid connection and into the second volume and as a result periodically compresses the working gas in the first volume. The membrane is constructed as a balloon or a bellows that surrounds the first volume. The compensation container contains working liquid and is connected to the pump.
