Hitachi has received an order for lithium-ion battery systems from General Motors Corporation (GM). Hitachi’s lithium-ion battery systems will be installed annually in more than 100,000 hybrid-electric vehicles (HEV), which is scheduled to launch in North America market in 2010. The order reflects GM’s recognition of the solid quality of Hitachi lithium-ion batteries, Hitachi’s proven record in a broad spectrum of lithium-ion battery technologies, including performance, cost, safety, durability and endurance, and its track record of having supplied the market with more than 200,000 cells since 2000. The lithium-ion batteries will be supplied by Hitachi Vehicle Energy, Ltd., a subsidiary of Hitachi, Ltd.

Owing to stricter environmental regulations and rising concern about fuel economy worldwide, Hitachi expects the global market for HEVs to continue expanding from the 410,000 unit level recorded in 2006 to 1.5 million units in 2010. Against this backdrop, Hitachi estimates that demand for HEV lithium-ion batteries will overtake that for the current mainstream nickel metal hydride batteries in 2015.

NVIDIA Corporation and Planar Systems are cooperating closely to produce display systems that will enable doctors to more effectively screen for breast cancer. The two companies are working to develop high-contrast, 10-bit grayscale display systems for use in mammography and other medical applications. Instead of developing specialty hardware, NVIDIA and Planar have developed a method of “pixel packing” that allows 10-bit or 12-bit grayscale data to be transmitted from an NVIDIA Quadro graphics board to a Planar Dome display using a standard DVI cable. Instead of three 8-bit grayscale channels, now two 10- or 12-bit channels are transmitted, providing up to 864 possible shades of gray at more than three times the image contrast of an 8-bit system.

Currently, digital mammography displays that rely on standard PC workstations are limited to 8-bit grayscale, which provides only 256 possible shades of gray for each pixel. Being limited to 256 shades-of-gray can sometimes obscure valuable data when an image is displayed; mammography systems and other medical sensors, however, are capable of greater degrees of contrast.
