  • Patent number: 11973544
    Abstract: A wireless system comprises a controlling node and multiple antenna processing nodes coupled to the controlling node but separated from each other. The controlling node receives (720) first soft bit information from a first antenna processing node, the first soft bit information corresponding to reception of a wireless transmission. Responsive to determining that it cannot decode transmitted bits using the first soft bit information, the controlling node requests (730) and receives (740) second soft bit information from a second antenna processing node, the second soft bit information also corresponding to the first wireless transmission from the wireless device and having been buffered by the second antenna processing node. The controlling node decodes (750) bits from the first wireless transmission using both the first and second soft bit information. The controlling node may then signal the antenna processing nodes that they can discard buffered information for the wireless transmission.

    Abstract: Disclosed is a method for determining a possible bacterial infection in a patient exhibiting symptoms selected from specific internal symptoms of disease, and/or diffuse and general manifestations of disease, and/or is a blood donor. The method includes: i) determining a) the level of a Rickettsia analyte in a sample 1 from a patient exhibiting symptoms, possibly combined with b) the level of a Borrelia analyte in a sample 2 from the same patient; ii) considering that the symptoms exhibited by the patient involve a) rickettsiosis if the level of the Rickettsia analyte in sample 1 is elevated, and b) borrelios if the level of the Borrelia analyte in sample 2 is elevated. For blood donors step, (ii) means that whole blood and blood fractions are considered to be infected with Rickettsia and/or Borrelia, respectively, when these levels are elevated.

  • Publication number: 20110104822
    Abstract: A method for determining the occurrence of an analyte subpopulation of heteroforms of a substance (=S) in a liquid sample. The method comprises as its main characteristic features the step of: (i) providing a flow path which a) comprises an outlet part and an inlet part, b) comprises a capture zone (CZ) containing a solid phase exhibiting an immobilized analyte specific binder (B) [=affinity counterpart to the substance] which is capable of affinity binding to S with an affinity that differs for the various heteroforms of S, and c) permits capillary suction from the outlet part for driving a liquid flow through CZ, (ii) flowing said liquid sample containing S in the downstream direction through CZ while S is captured by said binder B in CZ, (iii) determining the distribution of S along the flow direction in CZ by measuring the relative amount of S in at least one subzonei of CZ, and (iv) determining the occurrence of the analyte subpopulation based on the distribution determined in step (iii).

  • Publication number: 20100129932
    Abstract: A method for the determination of the occurrence of an analyte subpopulation of isoEPOs in a biological fluid comprising the steps of: i) providing a liquid sample deriving from the biological fluid and containing isoEPOs that are characteristic (=analyte isoEPOs) for said analyte subpopulation together with isoEPOs of other subpopulations, ii) separating the isoEPOs of said liquid sample into two or more fractions so that at least one of these fractions contains analyte isoEPOs which are enriched relative to other isoEPOs, by A) contacting the liquid sample with an isoEPO reactant under conditions allowing affinity complex formation between isoEPOs of the liquid sample and the affinity reactant, and B) fractionating and collecting the isoEPOs of the liquid sample into said two or more fractions, relating the occurrence of analyte isoEPOs in said at least one fraction to the occurrence of said analyte subpopulation in the biological fluid.

  • Patent number: 7100647
    Abstract: A forestry machine with devices for felling, trimming and cutting trees includes a control system with operating devices which are actuable by an operator. The operating devices control the felling, trimming and cutting devices, as well as the movements of the forestry machine. The operating devices are disposed discrete and separate from the forestry machine so that the working environment of the operator is free of the turnings, jolts and vibrations which the forestry machine is subjected to during operation. Preferably, the operator and the operating devices are placed in a load-carrying vehicle on which the forestry machine loads the felled trees. A system for forest felling includes a felling unit and an operating module. The operating module is disposed discrete and separate from the felling unit. Preferably, the operating module is disposed in a load-carrying vehicle which receives felled trees from the felling unit.

  • Patent number: 6490367
    Abstract: A system for administering certificates involves the generation, distribution and recall of certificates for public key systems. The generation comprises generating encryption keys and personalizing smart cards. The system is designed as a distributed system and is divided into a central unit with one or more associated terminal units. Each terminal and center is allocated unique certified identities. Mutual checking of access rights and data contents is carried out between the central unit and each terminal unit. An issued certificate can be traced back to the individual responsible for the issuing, compatibility with standards being seen to exist. Personalization of cards is integrated in each terminal.
