Patent number: 8320942Abstract: Embodiments of wireless device and method for communicating in a wireless network are generally described herein. Other embodiments may be described and claimed. In some embodiments, a wireless device establishes a link using a directional antenna in an initially selected direction with another wireless device. If the link in the initially selected direction deteriorates, the link may be reestablished in a previously identified alternate direction. In some embodiments, the initially selected direction and the alternate direction are jointly selected by both the first and second wireless devices.Type: GrantFiled: June 13, 2006Date of Patent: November 27, 2012Assignee: Intel CorporationInventors: Ali S. Sadri, Eduardo Casas, Duncan Kitchin

Patent number: 7238479Abstract: Single nucleotide polymorphisms (SNPs) in the gene encoding micromolar calcium activated neutral protease (mu-calpain) effect meat tenderness in bovine. These SNPs correspond to position 18 of exon 9 of Seq. ID No. 3, position 17 of exon 14 of Seq. ID No. 4, and position 185 on intron 19 of Seq. ID No. 4, of the CAPN1 gene encoding mu-calpain. Alleles wherein the SNP at position 18 of exon 9 encodes alanine at amino acid 316 of bovine mu-calpain, the SNP at position 17 on exon 14 encodes valine at amino acid 530 of bovine mu-calpain, and the SNP at position 185 on intron 19 is an cytosine, are all indicative of increased meat tenderness. Any one or all of these SNPs may be used as markers for selecting bovines having superior meat tenderness, and selecting animals for breeding purposes.Type: GrantFiled: December 18, 2003Date of Patent: July 3, 2007Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Timothy P.

Patent number: 6992621Abstract: Wireless communication and beamforming is improved by depopulating one or more ports of a passive beamformer such as a Butler matrix and/or by increasing the order thereof. In an exemplary implementation, an access station includes: a Butler matrix having “M” antenna ports and “N” transmit and/or receive (TRX) ports; wherein at least a portion of the “M” antenna ports and/or at least a portion of the “N” TRX ports are depopulated. In another exemplary implementation, an access station includes: a Butler matrix that has multiple antenna ports and multiple TRX ports; a signal processor; and a signal selection device that is capable of coupling the signal processor to a subset of the multiple TRX ports responsive to a signal quality determination, the signal selection device adapted to switch the signal processor from a first TRX port to a second TRX port of the subset of TRX ports.Type: GrantFiled: March 7, 2003Date of Patent: January 31, 2006Assignee: Vivato, Inc.Inventors: Eduardo Casas, Marcus da Silva
