Patent number: 8601295Abstract: 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.Type: GrantFiled: September 22, 2011Date of Patent: December 3, 2013Assignee: Oki Electric Industry Co., Ltd.Inventor: Yasutaka Kawamoto

Patent number: 6696294Abstract: 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.

Patent number: 6300118Abstract: 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.Type: GrantFiled: June 7, 1995Date of Patent: October 9, 2001Assignee: American Home Products CorporationInventors: Lloyd Chavez, Terri Wasmoen, Chengjin Huang

Patent number: 6167264Abstract: 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.Type: GrantFiled: February 20, 1998Date of Patent: December 26, 2000Assignee: Nokia Telecommunications OYInventors: Keijo L T Palviainen, Hannu-Pekka Salin
