Cambridge scientists are to design a architecture for superconducting spintronics computing, which could dramatically cut the energy costs of high-performance computing. Spintronics, which stores and processed data as the spin of electrons, in principle could save power compared with electronics because it avoids moving charge around. It is also potentially fast. “Given the energy-efficiency of …

UK looks to lead superconducting spintronics computing

As one of Edinburgh Royal High School’s less distinguished students, Alexander Graham Bell resented education conducted under strict discipline and consisting of memorising facts by rote. Bell derided the system of “giving out a certain amount of work which must be carried through in a given space of time and putting the children into orderly …

Fabless chip maker CambridgeIC has improved the accuracy and speed of its non-contact position sensing technology. Implemented in the firm’s CAM502 chip, it delivers 5,000 position sample/s, either linear or angular, and 14 bits of resolution using resonant inductive sensors. In operation, two passive resonant LC circuits, mounted on a single small PCB (see image) are …

Osram Opto has cut led light output droop by optimising its epitaxial processes. At a current density of 3A/mm², quantum efficiency of the has been increased 7.5%. Under laboratory conditions and driven at 3A/mm2, 740 lm typical luminous flux was produced from QFN LED package (6,200K, Cx 0.319, Cy 0.323, single-chip LDxyz). At low current densities …

Osram epitaxy boosts high power led efficiency

Researchers at the University of Southampton claim to have developed a graphene-based sensor that can detect harmful air pollution in the home with very low power consumption. The sensor, which is the result of a collaboration with the Japan Advanced Institute of Science and Technology (JAIST), detects individual CO2 molecules and volatile organic compound (VOC) …

Graphene-based sensor could detect sick buildings

Open APIs allow home users to tailor LED lights to respond to any cue. The APIs come with instructions to maximize the capabilities of the smart bulbs.
