Patent number: 9232333Abstract: The disclosed apparatus, systems, and methods provide a calibration technique for calibrating a set of microphones. The disclosed calibration technique is configured to calibrate the microphones with respect to a reference microphone and can be used in actual operation rather than a testing environment. The disclosed calibration technique can estimate both the magnitude calibration factor for compensating magnitude sensitivity variations and the relative phase error for compensating phase delay variations. In addition, the disclosed calibration technique can be used even when multiple acoustic sources are present. The disclosed technique is particularly well suited to calibrating a set of microphones that are omnidirectional and sufficiently close to one another.Type: GrantFiled: July 28, 2014Date of Patent: January 5, 2016Assignee: Analog Devices, Inc.Inventors: Juri Ranieri, David Wingate, Noah Daniel Stein

Patent number: 8792885Abstract: A method and system for controlling the provisioning of a device with information for accessing services of a wireless service provider via a wireless network is provided. The provisioning system initially stores automatic provisioning information on the device that includes the identification of wireless service providers that have the capability to automatically provision the device. When a user of the device wants to subscribe to a service of a service provider, the provisioning system requests an automatic provisioning service of the service provider to provide information describing available services and information needed to subscribe to those services. When the user selects a service and provides the needed information, the provisioning system retrieves provisioning information for the selected service from the service provider. The provisioning system stores the provisioning information on the device so that the device can then be used to access the selected service of the service provider.Type: GrantFiled: April 1, 2008Date of Patent: July 29, 2014Assignee: Microsoft CorporationInventors: Yue Chen, Alan W. Shen, Daniel Stein

Patent number: 8363465Abstract: A high speed and low power method to control and switch the magnetization direction and/or helicity of a magnetic region in a magnetic device for memory cells using spin polarized electrical current. The mapetic device comprises a reference magnetic layer with a fixed magnetic helicity and/or magnetization direction and a free magnetic layer with a changeable magnetic helicity and/or magnetization direction. The fixed magnetic layer and the free magnetic layer are preferably separated by a non-magnetic layer. The fixed and free magnetic layers may have magnetization directions at a substantially nonzero angle relative to the layer normal. A current can be applied to the device to induce a torque that alters the magnetic state of the device so that it can act as a magnetic memory for writing information. The resistance, which depends on the magnetic state of the device, is measured to read out the information stored in the device.Type: GrantFiled: March 4, 2011Date of Patent: January 29, 2013Assignee: New York UniversityInventors: Andrew Kent, Daniel Stein, Jean-Marc Beaujour
