Title: Optical amplifiers
Inventor: BRAY MARK E
IPC: H04B10/29
Filed: 2000-03-15
Abstract: In a WDM optical transmission system employing optical amplifiers in its transmission path, a supervisory signal channel, used for monitoring and controlling the operation of the amplifiers and spectrally separated from the data transmission, may be multiplexed with the data. A construction of amplifier is disclosed which is capable of being upgraded with an upgrade of the transmission system to include additional data handling capacity, for instance data transmission in an additional waveband and/or in the opposite direction, without interruption of the pre-upgrade data transmission path through the amplifiers. This is accomplished by the use of channel dropping and insertion filters disposed so that the amplifying data transmission path extends via the drop/insertion channel of those filters.

Title: Use of bisphosphonates for the treatment of osteogenesis imperfecta
Inventor: LLORET ANIBAL PEREZ
IPC: A61K33/16
Filed: 2000-05-11
Abstract: The present invention relates to a procedure applicable to medical preparations of bisphosphonates and their formulations for the treatment of Osteogenesis Imperfecta. This procedure consists of the administration of bisphophonate preparation to a patient requiring treatment in a first stage to obtain a defined bone mineral density.  Then the administration of the bisphosphonate preparation is interrupted in a second stage to allow for architectonic expression of bone. The length of the second stage can be determined by means of a tomography. In other words, the periods of administration or non-administration of the mineralizing agent are defined or controlled by precise osteologic variables and therefore are not fixed. If during the second stage the cortical mineral density drops by 6-10% of the maximum value previously obtained, administration of bisphosphonate preparation should be resumed until the corresponding maximum adjusted value is reached again. The proposed procedure of a period comprising bisphosphonate administration followed by a period of non-administration of the bisphosphonate agent improves fracture resistance, provided that the length of both periods is controlled by defined osteologic variables.

Inventor: GONZALO STEVEN M
IPC: G06K19/00
Filed: 2000-05-19
Abstract: A method and system for initializing and distributing information cards that contain information for configuring a computer system. The information card contains configuration information relating to the configuration of a user's computer.  A card generating computer system generates the information cards with user-specific configuration information. The card generating computer system receives a request for an information card from a user of the computer and directs the execution of a transfer program at the user's computer. That transfer program collects configuration information from the user's computer and sends the collected configuration information back to the card generating computer system. The card generating computer system then stores the received configuration information on the information card. The information card is then sent to the user. The user can use the information card at a publicly accessible computer system to configure that computer system in a similar way to which the user's computer system is configured.

Title: Sound generator and video game machine employing it
Inventor: KONDO KOJI
IPC: A63F13/10
Filed: 1998-11-19
Abstract: When any of push-button switches on a controller 40 is pressed in a sound input mode, a video game machine body 10 generates and temporarily stores frequency data of a tone corresponding to the pressed switch. At this time, when a joystick 45 on the controller 40 is tilted to a predetermined direction, the video game machine body 10 changes the generated frequency data according to the amount of tilt of the joystick 45 . It is therefore possible to input various sounds in tone using a limited number of switches . The frequency data stored in the video game machine body 10 is read later to be converted into audio signals, and outputted from a speaker incorporated in a CRT display 30. When a melody based on the inputted sound coincides with a melody set in advance, the video game machine body 10 makes various changes in the progress of the game. For example , a hero character is warped to a position that is different from the present position, or provided with various items.
