  • Patent number: 8601295
    Abstract: A network includes nodes that transmit information to each other. Some nodes operate intermittently; other nodes operate continuously. Information is transmitted to an intermittently operating node by a handshaking protocol in which the intermittently operating node indicates that it is ready to receive. Information is transmitted to a continuously operating node without such handshaking, thereby saving time and power. Each transmitting node has a memory storing information indicating which other nodes require handshaking.

  • Patent number: 6696294
    Abstract: The present invention provides methods for generating and identifying mutations in any target gene of a polyploid plant species. In a preferred aspect of the present invention, a plant is constructed and/or selected that has at least one copy of a functional, target gene located exclusively in only one of its homoeologous, or homologous, genomes. Seed derived from the selected plant are then contacted with an effective amount of at least one mutagenic agent, the treated seed are germinated and the seeds or plants derived therefrom, are screened for mutations in the target gene. Thus, the inventive concepts set forth herein can be used to create, select and identify mutations in any target gene of any suitable polyploid plant, thereby providing a source of numerous, readily-identifiable mutations that can, if so desired, be used in crosses to develop unique new crop cultivars.

  • Patent number: 6428985
    Abstract: Disclosed is the surprising discovery that a single amino acid provides the demarcation between the immunosuppressive and immunostimulatory properties of the cytokine, IL-10. The present invention thus provides mammalian and human IL-10 genes and polypeptides that have immunosuppressive properties, without immunostimulatory side-effects. Also provided are various methods of using the new IL-10 constructs, both in vitro and in vivo, particularly in sole or combination therapies involving immunosuppression, such as in the treatment of inflammatory diseases and disorders, and in transplantation.

  • Patent number: 6300118
    Abstract: The present invention pertains to the prevention or lessening of disease in cats caused by Feline Immunodeficiency Virus (FIV). Prevention or lessening of disease is understood to mean the amelioration of any symptoms, including immune system disruptions, that result from FIV infection. The invention provides for a plasmid which encodes the FIV genome where said genome has had a portion of the gag gene, specifically the p10 (nucleocapsid) coding region, or a portion thereof, deleted. This deletion prevents the production of functional or whole p10 protein, which in turn, prevents the packaging of RNA into virions produced from transfection of this plasmid into an appropriate host cell, resulting in virions which do not contain RNA. Such virions will be described as “empty” virions. The invention also encompasses host cells transformed with the plasmid which produce the empty virions, and the empty virions themselves.

  • Patent number: 6167264
    Abstract: Visitor location register and a method for handling an outgoing and an incoming call in a mobile communications system employing a multinumbering scheme. Signalling originating from a mobile services switching center (MSC) contains in case of a mobile-originating call the directory number of the calling subscriber and, in call forwarding, the redirecting number. This directory number is obtained from the visitor location register (VLR). All the directory numbers for different basic services of the mobile subscriber are transferred from the home location register (HLR) to the VLR. The VLR is thus capable of providing the MSC with the correct one of multiple directory numbers according to the basic service related to the call.
