  • METHOD WHICH PERMITS A BLOCK-BASED FILE TO BE PLAYED OUT DURING TRANSMISSION
    Publication number: 20110305266
    Abstract: A file (FI) is transmitted via a first channel (CH1). In addition, a second channel (CH2) is used to transmit play parameters (D1, D2, R1, R2) which comprise at least one set (Di, Ri) of information about a play rate (R1, R2) and a delay time (D1, D2) for the file (FI) which is to be transmitted by the first channel (CH1). On the basis of the play parameters (D1, D2, R1, R2), it is possible to determine a time for starting to process the file (FI) which is to be transmitted.

  • MICROCAPSULE SUSPENSIONS INCLUDING HIGH LEVELS OF AGRICULTURALLY ACTIVE INGREDIENTS
    Publication number: 20110301036
    Abstract: Materials and methods for the formation of microcapsules that include a high concentration of agriculturally active ingredients (AIs) and a lipophilic polymer encapsulated within a polymeric shell formed via an interfacial polycondensation reaction. Under some conditions, these microcapsules may be formed using less lipophilic solvent than is required using convention microencapsulation techniques. These inventive methods include forming an oil-in-water emulsion in some cases using a first polymer as a lipophilic solvent for the AI and forming a microcapsule that includes the AI and polymer. Other methods include forming a microcapsule that includes a lipophilic monomer, agriculturally active ingredient and initiator having a polymeric shell then elevating the temperature to initiate polymerization of the monomer with the microcapsule.

  • Method and communication device for interference cancellation in a cellular TDMA communication system
    Patent number: 8073088
    Abstract: A system and method for interference cancellation of received data via a communication channel in a cellular communication system having corresponding channel impulse response coefficients. Linear filtering of the received data is performed and thereafter a non-linear detection is executed to get detected data by non-linear signal processing. Filter coefficients are determined for linear pre-filtering of the received data to suppress non-Gaussian interference. The pre-filtered data is further processed by non-linear detection to get detected data.
