Patent CA-2305254-C (CA)
Inventor: DAVIDSON CLAYTON L
IPC: H04N7/08
Filed: 1998-10-01
Granted: 2003-04-15
Abstract: L'invention concerne un procédé et un dispositif permettant la lecture d'une empreinte de signal vidéo numérique aux fins de "copie unique". L'empreinte intégrée a deux versions: une indiquant l'interdiction de copie et une autre indiquant la copie unique, la différence tenant à un seul bit d'empreinte. L'empreinte comporte des bits supplémentaires représentant un attribut numérisé (caractéristique d'image) d'une trame ou d'un signal vidéo spécifique: par exemple, valeur moyenne de l'amplitude d'un champ vidéo. La trame dont l'attribut est incorporé à l'empreinte a un marqueur de champ (ou de trame), sous la forme d'un signal spécial situé dans la partie de surbalayage de la trame. Un enregistreur vidéo conforme vérifie l'empreinte et le bit de copie unique (48-54), extrait de l'empreinte (56) l'attribut associé et le compare (68) à l'attribut (58) mesuré de la trame vidéo marquée. L'enregistrement est validé seulement si la valeur d'attribut extraite correspond à la valeur d'attribut mesurée. Pendant l'enregistrement (70), les marqueurs de trame sont éliminés (72), ce qui permet d'éviter les copies en seconde génération du signal vidéo enregistré, et le bit de copie unique est mis sur copie interdite.

Abstract: A device and method for outer-loop power control in a discontinuous transmission mode in a CDMA mobile communication system. In an outer-loop power control method for a non-frame data transmission period of a dedicated control channel (DCCH) which transmits frame data discontinuously, the signal-to-noise ratio (SNR) of power control bits (PCBs) received at a mobile station from a base station is measured for the frame period, and it is determined whether the frame has errors based on the measured SNR. A closed-loop power control threshold is increased if a frame error exists and decreased if no frame errors exist.

Abstract: This invention is a neurological control system (999) for modulating activity of any component or structure comprising the entirety or portion of the nervous system, or any structure interfaced thereto, generally referred to herein as a "nervous system component". The neurological control system generates neural modulation signals delivered to a nervous system component through one or more intracranial (IC) stimulating electrodes (37) in accordance with treatment parameters. Such treatment parameters may be derived from a neural response to previously delivered neural modulation signals sensed by one or more sensors (247), each configured to sense a particular characteristic indicative of a neurological or psychiatric condition. Neural modulation signals include any control signal which enhances or inhibits cell activity. Significantly the neurological control system considers neural response, in the form of the sensory feedback, as an indication of neurological disease state, and/or responsiveness to therapy, in the determination of treatment parameters.
