Patent number: 9357054Abstract: A handheld electronic device determines its position in a moving vehicle based on changes in air pressure that occur when the vehicle undergoes acceleration. Based on a direction of acceleration that correlates to a subsequent reduction in air pressure, a determination is made as to whether the device is in the front left, front right, back left, or back right quadrant of the vehicle. The device then alters its configuration based on the quadrant in which it is located.Type: GrantFiled: March 11, 2015Date of Patent: May 31, 2016Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Arnaud Marie Froment, Gy Stuart Fullmer, Wendy Chiu Fai Wong, Sean Thomas Congden, Seetha Lakshmi Annamraju, Kenneth Paul Kiraly, Brett Nathan Lynnes

Patent number: 7388919Abstract: A system that adapts wireless link parameters for a wireless communication link. A measure is determined of errors occurring in communication over a wireless link. In a case that the measure of errors corresponds to more errors than a first predetermined threshold, communication changes from a first set of wireless link parameters to a second set of wireless link parameters. The second set of wireless link parameters corresponds to higher error tolerance than the first set of wireless link parameters. In a case that the measure of errors corresponds to fewer errors than a second predetermined threshold, communication changes from the first set of wireless link parameters to a third set of wireless link parameters. The third set of wireless link parameters corresponds to lower error tolerance than the first set of wireless link parameters. Preferably, the measure of errors is determined by monitoring a number of NACK messages and a number of ACK messages that occur.Type: GrantFiled: September 20, 2005Date of Patent: June 17, 2008Assignee: Aperto Networks, Inc.Inventors: Subir Varma, Reza Majidi-Ahy, Joseph Hakim, Wendy Chiu Fai Wong

Patent number: RE45620Abstract: A system method that adapts wireless link parameters for a wireless communication link. A measure is determined of errors signal quality occurring in communication over a wireless link. In a case that the measure of errors signal quality corresponds to more errors than a first predetermined threshold, communication changes from a first set of wireless link parameters to a second set of wireless link parameters. The second set of wireless link parameters corresponds to higher error tolerance than the first set of wireless link parameters. In a case that the measure of errors signal quality corresponds to fewer errors than a second predetermined threshold, communication changes from the first set of wireless link parameters to a third set of wireless link parameters. The third set of wireless link parameters corresponds to lower error tolerance than the first set of wireless link parameters.Type: GrantFiled: April 11, 2013Date of Patent: July 21, 2015Assignee: Wi-LAN, Inc.Inventors: Subir Varma, Reza Majidi-Ahy, Joseph Hakim, Wendy Chiu Fai Wong
