Title: Host rejection filtering in a digital audio broadcasting system
Inventor: NEASE GREG ALAN
IPC: H04J11/00
Filed: 2000-10-17
Abstract: A digital receiver for receiving an analog host signal with one or more digital sidebands includes a bandreject filter arranged at least in part in an intermediate frequency (IF) processing stage of the receiver. In an illustrative embodiment, first and second digital sidebands are transmitted on either side of a frequency modulated (FM) analog host signal in a hybrid in-band on-channel (HIBOC) digital audio broadcasting (DAB) system. The received composite signal is filtered in the IF processing stage of the receiver by the bandreject filter in order to substantially attenuate the analog host signal while passing the digital sidebands. The bandreject filter may be arranged in the IF processing stage so as to filter the analog host signal from the composite signal at a point prior to an input of an automatic gain control (AGC) circuit, such that the AGC operating point is determined primarily by the digital sidebands. The bandreject filter may have a group delay characteristic for a portion of a frequency spectrum associated with the digital sidebands that is selected to equalize a corresponding group delay characteristic for a signal path of the receiver.

Title: Cable de manipulation conducteur
Inventor: WILL ROBERT
IPC: H01B7/04
Filed: 1999-03-17
Abstract: La présente invention concerne un câble (1) destiné à être utilisé pour déployer des équipements dans un trou de forage. Ce câble comprend une partie centrale conductrice (12) isolée d'au moins une couche (18, 20) de câbles blindés par une couche isolante (16). Afin de contrôler la migration des fluides de forage par le système de contrôle de pression, les pores (24) situées entre les câbles blindés (22) sont remplis de matériau élastique qui empêche les fluides de forage de s'infiltrer dans ces pores (24) et d'endommager le câble (10). Le matériau résilient se fixe fortement aux câbles blindés (22) les empêchant ainsi de se séparer, même après une utilisation répétée ou une perte de tension. Par conséquent, le blindage rempli de matériau élastique assure une force mécanique satisfaisante permettant de soutenir des charges relativement lourdes. Le matériau résilient assure également au câble une surface extérieure lisse.

These parameters may also be used to determine other information about the functioning of the pacemaker. The present invention may also be applied to the determination of tachycardia of an intrinsically paced heart, as well as other applications.

Title: Method to configure a communication link for data transmission
Inventor: SOCHER GUIDO
IPC: H04M11/00
Filed: 1999-09-25
Abstract: The invention relates to a method and a device for the op-timized negotiation of communication parameters for a transmis-sion of data in communication links. A list is initialized in a communication initializing device and is sent one after another to all devices involved in the communication during the connec-tion set-up phase. Each of the devices adds its own and most suited transmission parameters to the list. Said parameter list is sent to the communication initializing device by the last device involved in the communication. The initializing communication device finally selects the transmission parameters. The parameter list established in this way is one after another sent to all devices involved in the transmission to inform them on the valid param-eter selection. Each device configures its parameter setting or a corresponding connection by means of the received parameter list.  Thus, a configuration of the devices involved in the communica-tion is effected for the subsequent data transmission.
