Patent action on software by A.T.&T

Article Abstract:

AT and T sends letters to numerous software publishers informing them that they are infringing on a 1985 windowing technology patent held by AT and T's Bell Laboratories. The patent covers the basic technology used by most developers of workstation applications to enable multiple programs to run simultaneously in multiple 'windows' that can be visible or invisible to the user. The window managing technology is fundamental to most workstation applications based on the X Windows standard. Members of MIT's X Consortium, a group of software publishers who create applications for the Unix operating system, are among those contacted by AT and T. AT and T states there is nothing unusual in the letters, claiming they are part of normal industry practice.

Using computer engineering to mimic the movement of the bow: researchers are trying to capture the complexity of musical information

Article Abstract:

The Massachusetts Institute of Technology's Media Laboratory attempts to capture the subtleties and complexities of musical information on computer. Researchers at the Media Lab uses a Sun Microsystems workstation that controls a grand piano and 64 music synthesizers. The research aims to find new ways to compose, play and record music. Computerized synthesizers have been unable to match the flexibility and fullness of musical instruments in the past, but the Media Lab is using more sophisticated computer-based technologies that hope to reproduce the nuances of a live musical performance. The lab focuses on imitating gestures, or the subtle component in musical performance that makes each performance different.

Training computers to note images

Article Abstract:

Researchers at the Massachusetts Institute of Technology's (M.I.T.) Media Laboratory are developing the proper tools to equip computers with the capabilities to sort through enormous electronic libraries of pictures and be able to recognize specific images in a similar fashion that words and phrases are recognized. New machines that can integrate the power of computers with video and audio technologies have limited abilities to sort through and retrieve visual images. Currently, searching large data bases of visual images requires a user to type in very detailed descriptions of each picture. Researchers at M.I.T. expect more developments in image recognition over the next five years.
