Patent number: 8930136Abstract: A personal navigation device configured to determine heading readings continuously using data from a sensor in the personal navigation device. Heading readings are selected corresponding to a periodic event. A representative heading is determined from the selected heading readings. When a portion of the selected heading readings has a value within a range of the representative heading, a static heading indicator is asserted to indicate the personal navigation device is moving in a static heading. The static heading indicator may be used to smooth an estimated trajectory of the personal navigation device.Type: GrantFiled: April 1, 2011Date of Patent: January 6, 2015Assignee: Texas Instruments IncorporatedInventors: Tarkesh Pande, Jaiganesh Balakrishnan, Deric Waters, Goutam Dutta, Jayawardan Janardhanan, Sthanunathan Ramakrishnan, Sandeep Rao, Karthik Ramasubramanian

Patent number: 8761028Abstract: Apparatus, systems, and methods disclosed herein operate to calibrate path loss parameters corresponding to a communication channel between wireless stations, including a path loss exponent. A time-of-flight (TOF) associated with packet transmissions traversing a path between a first wireless station and a second wireless station is measured. A path length D1 corresponding to the path is calculated from the TOF measurements. One or more received signal strength (RSS) measurements corresponding to the packet transmissions are then made at the first wireless station. The path loss exponent associated with the path is calculated from D1 and the RSS measurements. Some embodiments may also measure RSS values associated with transmissions from a third wireless station. The latter measurements may be used in conjunction with the previously-determined path loss exponent to derive an unknown transmission path length between the first and third wireless stations.Type: GrantFiled: August 29, 2011Date of Patent: June 24, 2014Assignee: Texas Instruments IncorporatedInventors: Leonardo William Estevez, Deric Waters

Publication number: 20110071759Abstract: A system and method for controlling a navigation receiver is disclosed. A current position is determined using the navigation receiver and then the navigation receiver is placed in a power-save mode. The current position is updated using information from position sensors. The navigation receiver is temporarily placed in an active mode at intervals to determine an intermediate position. The current position is also updated using the intermediate position. The navigation receiver may be a GNSS receiver, a cellular receiver, a WiFi receiver, or another position-fixing device. The position sensors may be accelerometers, gyroscopes, electronic compasses or mapping data. A power-save controller controls the power-save or active mode of the navigation receiver. A sensor conditioning circuit pre-processes the data from the position sensors before providing the data to the power-save controller. During the power-save mode, an RF subsystem and/or a baseband subsystem of the navigation receiver may be turned off.Type: ApplicationFiled: September 21, 2010Publication date: March 24, 2011Applicant: TEXAS INSTRUMENTS INCORPORATEDInventors: Tarkesh Pande, Goutam Dutta, Deric Waters
