Abstract: Des détecteurs linéaires multiutilisateurs espace-temps sont décrits qui combinent le traitement en réseau, la détection en râteau, la détection multiutilisateur et qui satisfont un critère minimum d'erreur moyenne quadratique. Les deux modes de réalisation peuvent être mis en uvre de manière adaptée de façon à rendre compte des sources inconnues d'interférence. La mise en uvre adaptative du premier mode de réalisation d'un détecteur linéaire espace-temps nécessite des estimations explicites des coefficients de canal. D'autre part, la mise en uvre adaptative du second mode de réalisation ne nécessite pas ces estimations étant donné qu'elles peuvent être obtenues de manière adaptative. Ces deux détecteurs fournissent des avantages de performance significatifs vis-à-vis des détecteurs espace-temps à utilisateur unique et des détecteurs multiutilisateurs qui ne rendent pas compte des interférences CDMA provenant de sources inconnues.

Title: Method for variable block scheduling indication by an uplink state flag in a packet data communication system
Inventor: TURINA DALIBOR
IPC: H04W72/14
Filed: 1999-01-29
Granted: 2011-03-22
Abstract: A packet data communications system uses a USF (Uplink State Flag) transmitted on the downlink and interleaved with downlink data, to schedule traffic on the uplink for one or several mobile users utilizing the same physical channel. The USF indication is made variable and defined in the control signaling at setup of a packet transmission. A USF indicates to a mobile that one or several consecutive radio blocks is reserved for uplink transmission from a specific mobile. The mobile does not have to receive the USF during the remaining period defined by the number of radio blocks scheduled. The solution is especially advantageous in combination with adaptive antennas when all radio blocks on the downlink transmissions do not have to be broadcast to all users on a certain channel.

Granted: 2004-08-10
Abstract: A valve insert comprises a bushing assembly, a piston assembly and a spring. Its design prevents non-longitudinal movement of the piston assembly as it is moved within the longitudinal bore of the bushing assembly. This virtually eliminates the bell clapper effect commonly suffered by many of the valve inserts currently used in the industry. The design of the valve insert also avoids the pressure imbalances inherent to the prior art valve inserts. The valve insert is designed to fit snugly and sealingly within a suitable borehole, such as the fill and cut-out boreholes of an ECP manifold assembly.

Title: Underwire water weight turbulence sensor
Inventor: HU HUNG-TZAW
IPC: D21F1/06
Filed: 1999-04-13
Granted: 2008-06-17
Abstract: A system of providing on-line turbulence measurements in a papermaking machine. The measurements are used to perform on-line adjustments to turbulence-inducing and adjusting elements in the papermaking machine to optimize final sheet product quality. Turbulence measurements are obtained using water weight sensors (23) in the wet end of the papermaking machine, specifically, under wire water weight measurements. Water weight readings are correlated to turbulence intensity levels. A turbulence processing sensor (25) sorts accumulated water weight measurement readings into intensity level intervals to obtain turbulence measurements or a turbulence profile. The trubulence measurements or profile is provided to a machine element controller (26) which uses the measured turbulence information and target turbulence information to generate control signals. Water weight sensors can obtain independent machine direction (MD) and cross machine direction (CD) water weight measurements and consequently independent turbulence measurements can be determined so that turbulence can be controlled in both directions. Machine elements are controlled so that turbulence remains uniform across the CD and so that the MD turbulence profile is optimized to resemble a target profile.
