SanDisk announced its new Extreme IV CompactFlash cards. These
new cards will be available in 2, 4 and 8 GB capacities and are rated as
delivering 'minimum read and write speeds' of 40 MB/sec. They are also
designed to be able to withstand extremes of temperature from -25°C
(-13°F) to 85°C (185°F). |
World’s First 100+ Million Pixel CCD Image Sensor.
This single sensor, developed for astronomy by DALSA Semiconductor, has
10,560 x 10,560 pixels, 111 million in total. The active area of the
sensor measures approximately four by four inches and has a 9 µm pixel
pitch. |

Kodak and Lexar Join Forces
Kodak High Performance memory cards (initially available in SD format),
offered by Lexar, are ideal for high-speed processing and rapid-fire
still shooting. |

Revolutionary new chip delivers better pictures for less power
Two professors at the University of Rochester in New York have
designed a prototype CMOS chip that uses a fraction of the energy used
today, captures better images and can run for years on a single battery. |

Kodak launches high resolution CCDs with 39 megapixels. The
new sensor will be used in upcoming digital backs. |

Two technologies, cable modems and Asymmetric Digital Subscriber Line
(ADSL), currently dominate the industry. Both are not fast enough to
support digital television and Video-on-Demand. However, another DSL
technology known as very high bit-rate DSL (VDSL) is able to
provide an incredible amount of bandwidth, with speeds up to about 52
megabits per second (Mbps). |

Quantum computers, which tap the
properties of particles like atoms, photons and electrons to carry out
computations, could potentially use a variety of schemes: individual
photons controlled by optical networks, clouds of atoms linked by laser
beams, and electrons trapped in quantum dots embedded in silicon chips. |

Serial
ATA II specs define up to 3Gbps (300MB/s) throughput that doubles the
performance of the previous standard version. |

When light rays pass through normal optical glass, the red and blue
light rays bend at slightly different angles. This dispersion results in
colour fringing and lack of sharpness. Modern techniques to
correct this chromatic aberration are effective with normal and
wideangle lenses. But telescopic lenses magnify the slight variation in
focus between red and blue light rays. So Nikon developed ED
(Extra-low Dispersion) glass which is especially designed to provide
precise optical colour correction. The result ? Brighter, clearer
viewing with remarkable resolution. |
