Title: Dynamic echo canceller and parameter selection in telephony systems
Inventor: DREYFERT TORKEL
IPC: H04B3/20
Filed: 1998-01-16
Granted: 2000-02-01
Abstract: An echo canceller pool configuration is provided that allows a user to predetermine and individualize the echo cancellation parameter settings for any echo canceller in the pool, based on prior knowledge of the echo path characteristics of the specific transmission route to be used for an ensuing call. The echo canceller with the individualized parameter settings is then switched into that route for the duration of the call. For example, at call setup, once a trunk route has been identified that will be used to complete the call, a ""flag"" is retrieved that is associated with that specific route. That ""flag"" identifies specific echo canceller parameter settings to be used for that route. Those parameter settings are downloaded to the echo canceller device selected from the pool, and that device is then switched into the specific trunk involved. An operator can thereby optimize echo cancellation in the system and significantly improve speech quality overall.

Title: Processing apparatus
Inventor: SADA TETSUYA
IPC: G03F7/30
Filed: 1998-02-04
Granted: 2001-02-21
Abstract: The object of the present invention is to provide a processing apparatus for preventing failure due to static charge by suppressing the electrification of a substrate, typically a LCD substrate. To achieve the object, the present processing apparatus comprising: a hold means to hold a substrate, such as a LCD substrate; and a processing liquid supply means to supply processing liquid to the surface of the substrate. The holding means comprises a loading section to be placed with the LCD substrate. The loading section is formed of a synthetic resin member. In accordance with the present invention, because the loading section of the holding means is formed of synthetic resin, the electrification of the substrate is decreased. Therefore, the electrification of the substrate is suppressed and various failures due to the electrification is prevented. Further, it is applicable to prevent the failure caused by discharge noise generated by the discharging phenomenon in transferring the substrate. On the upper or lower portion of the holding means, discharging liquid, such as ionized pure water or ionized gas, is applied toward the holding means, so as to depress the electrification of the holding means and further remove the electrification of the holding means. Therefore, it can better prevent failures of the devices already on the substrate due to the electrification of the substrate by suppressing the electrification and further prevent failures caused by discharge noise generated by the discharging phenomenon in transferring the substrate. In addition, by increasing the thickness (length) of the dielectric, i.e., the thickness (distance) of the holding means and the shaft portion, the amount of the electrification on the substrate can be decreased.
