Title: Reception automatic gain control system and method
Inventor: NAKANO TAKAYUKI
IPC: H04W52/52
Filed: 1997-06-03
Granted: 2001-09-11
Abstract: An automatic gain control system is disclosed which incorporates a control error amplitude limiting circuit to provide fine gain control for relatively small control error values, while providing limited gain renewal values to maintain amplifier stability for relatively large control error values. In another embodiment, an automatic gain control system is disclosed which incorporates a variable scaling means which scales the control error with coefficients selected in accordance with the positive or negative sign of the control error to provide maximum control loop response rates which are the same for both increases and decreases in signal power.      Automatic gain control systems and methods are disclosed which respectively limit the control error amplitude and scale the control error with coefficients selected on the basis of the cotnrol error being either positive or negative, to provide improved, more precise, and more symmetrical amplifier gain control.

Abstract: A dynamic sealing arrangement for connectors carrying high pressure fluids such as are used in the oil and gas industry for transferring production fluids from drilling installations to transport vessels. The sealing arrangement comprises a primary and a second U-shaped hydraulically operated sealing ring with open sides facing away from the junction of the connectors in the direction of the fluid leakage path. Barrier fluid under a pressure higher than that of the production fluid is supplied to the chamber between the sealing rings and independently to the open side of the secondary seal. The primary seal thus experiences a pressure differential and is activated. The secondary seal experiences a pressure differential and is activated only if the primary seal fails. Thus the secondary seal does not wear under normal usage of the connectors and is brought into operation automatically, efficiently and without delay when the primary seal is damaged. Repair of the primary seal can then be accomplished at the next routine service avoiding the need to shut down the production line immediately as was the case with known sealing arrangements. Substantial cost savings are achieved.

Granted: 2003-06-03
Abstract: An apparatus and method that precisely controls the amount of liquid dispensed from dispensing apparatus onto an article. The present invention controls the weight of the dispensed liquid by using a force transducer that precisely weighs the article and dispensed liquid during the dispensing process. This weight value is input to a computer controller of an automatic dispenser that embodies a computer program that controls a liquid dispensing pump. Liquid is dispensed until the desired weight of liquid that is to be dispensed is reached, defined by an upper limit in the program. The flow of dispensed liquid is reduced when the weight limit is approached, and is stopped when the weight limit is reached. Thus, in the present invention, the weight (orvolume) of the dispensed liquid is controlled in real time during the dispensing process. Closed loop control of the dispensing pump using liquid weight as the controlling variable improves the volumetric accuracy and repeatability of the dispensing process.

Abstract: Système permettant de déterminer l'approbation d'une transaction à devises multiples entre un commerçant et un client impliquant un change de devises. Les obligations du commerçant et du client concernant une telle transaction peuvent être fixées au moment de la transaction. Les risques encourus par les parties, associés jusque-là au change de devises, sont donc réduits à un minimum. Les parties engagées dans une transaction à devises multiples autorisent une entité approbatrice à régler la transaction. L'autorisation est accordée par le fait que le client et le commerçant établissent des comptes sachant que des transactions seront soumises à l'entité qui détient les comptes et qu'elles seront traitées par ladite entité. Les parties transmettent des données représentant la transaction à l'entité approbatrice. Ces données comportent une somme dans une première devise qu'un client est prêt à payer pour un produit et un prix dans une deuxième devise qu'un commerçant est prêt à accepter pour ledit produit. L'autorité approbatrice approuve la transaction sur la base de critères prédéterminés. Une fois la transaction approuvée, l'entité approbatrice peut régler la transaction à sa discrétion, assumant ainsi le risque associé au change des devises. Toutefois, les parties ne courent aucun risque. Le client paiera la somme dans le première devise et le commerçant recevra le prix dans la deuxième devise. Il s'agit là de valeurs connues et acceptées par les parties au moment de la transaction.
