Patent number: 10557944Abstract: Disclosed are devices, systems and techniques for propagating a system time maintained at a mobile device in a lower power mode using a sleep counter advanced by an XO crystal oscillator. In one particular implementation, a mobile device obtains initial and subsequent satellite positioning system fixes while in a higher power mode. Between the initial and subsequent position fixes, the mobile device may transition to a lower power mode during which measurements of a temperature of the XO crystal oscillator may be obtained.Type: GrantFiled: September 4, 2015Date of Patent: February 11, 2020Assignee: QUALCOMM IncorporatedInventors: Jie Wu, Dominic Farmer, Lalitaprasad Daita, Emilija Simic

Patent number: 7551129Abstract: Method and apparatus to implement a “virtual” real-time clock at a terminal based on time information from multiple communication systems. At least one system (e.g., GPS) provides “absolute” time information for the virtual real-time clock, and at least one other system (e.g., a cellular system) provides “relative” time information. The virtual real-time clock is “time-stamped” with absolute time as it becomes available from the first system. Relative time (which may be received from multiple asynchronous transmitters) is mapped to the timeline of the virtual real-time clock as it is received from the second system. Absolute time at any arbitrary time instant on the timeline may then be estimated based on the absolute time from the first system and the relative time from the second system. Absolute times from the first system for two or more time instants may also be used to calibrate the relative time from the second system.Type: GrantFiled: October 27, 2006Date of Patent: June 23, 2009Assignee: QUALCOMM IncorporatedInventor: Dominic Farmer

Publication number: 20070205941Abstract: A mobile communications device uses a method for determining position that involves a positioning filter, such as a Kalman filter, which is initialized with measurements from reference stations such as satellite vehicles and/or base stations which may be acquired during different epochs. Accordingly, the positioning filter may be used for position estimation without the need to first acquire at least three different signals during the same measurement epoch.Type: ApplicationFiled: March 6, 2007Publication date: September 6, 2007Applicant: QUALCOMM INCORPORATEDInventors: Wyatt Riley, John Blackmer, Dominic Farmer, Rayman Pon

Publication number: 20060178154Abstract: A network sends to a user equipment (UE) an indication (e.g., a request for permission) to perform a position fix for the UE. The network also selectively sends to the UE a pre-session command for an action related to position determination. For example, the command may direct the UE to (1) clear all or a portion of location-related data at the UE prior to performing the position fix, (2) send back a position estimate for the UE, if available, or (3) apply a time offset and/or a position offset in performing the position fix. The UE sends to the network an acknowledgment (e.g., a grant of permission) to perform the position fix. The UE also performs the action indicated by the command (if any) received from the network prior to or in conjunction with performing the position fix. The network and UE perform the position fix for the UE.Type: ApplicationFiled: February 4, 2005Publication date: August 10, 2006Inventor: Dominic Farmer
