Patent number: 10755690Abstract: A headphone device includes a speaker housing, a first feedforward microphone, and a second feedforward microphone. The first feedforward microphone is coupled to the speaker housing at a first location, and the second feedforward microphone is coupled to the speaker housing at a second location. The headphone device also includes an active noise cancelling (ANC) circuit configured to generate an anti-noise signal based on at least one of a first signal from the first feedforward microphone and a second signal from the second feedforward microphone. The headphone device also includes a speaker configured to generate an audio output at least partially based on the anti-noise signal.Type: GrantFiled: June 11, 2018Date of Patent: August 25, 2020Assignee: QUALCOMM IncorporatedInventors: Asif Mohammad, Catalin Lacatus, Deepak Kumar Challa, Louis Dominic Oliveira

Patent number: 9686743Abstract: A method for a tracking device optimizing power to remain reachable for a desired period based on evaluated wide-area-network conditions. The tracking device may communicate via a power-intensive long-range transceiver and may continually measure service conditions related to network communications. The tracking device may periodically calculate statistical information describing the service conditions, such as a percentage of time in which the tracking device was out-of-network-service. Based on the statistics, the tracking device may operate in an optimization mode to conserve power when out-of-network-service. In an embodiment, the tracking device may calculate the statistics based on evaluation periods defined by predefined numbers of out-of-network-service occurrences, predefined time periods, and/or a hybrid of both.Type: GrantFiled: May 15, 2015Date of Patent: June 20, 2017Assignee: QUALCOMM IncorporatedInventors: Catalin Lacatus, Harleen Kaur Gill, Eric Carl Rosen, Hemish Parikh, Thomas Doyle

Patent number: 9651673Abstract: Methods, systems and devices are provided for operating a GPS engine in an active geofence monitoring state for no more than a first QoS period to obtain a first GPS fix. The GPS engine may also be set to operate in the active geofence monitoring state for no more than a second lower QoS period to obtain a second GPS fix in response to determining the first GPS fix was not obtained. The method may determine whether a geofence breach is detected in response to determining the GPS engine obtained the first GPS fix. The GPS engine may be set to operate in the active geofence monitoring state for no more than the second QoS period to obtain the second GPS fix in response to determining the geofence breach is not detected. The GPS engine may thus operate in the active geofence monitoring state to obtain the second GPS fix.Type: GrantFiled: March 15, 2013Date of Patent: May 16, 2017Assignee: QUALCOMM IncorporatedInventors: Catalin Lacatus, Alaa-addin Moussa, Harleen K. Gill, Hemish K. Parikh

Patent number: 9276630Abstract: Systems, methods, and devices of the various embodiments provide modified frequency hopping patterns that enable synchronization of a wireless tracking device with a beacon signal that defines a predetermined area (i.e., beacon fence). In an embodiment, a beacon may transmit a beacon signal according to a modified frequency hopping pattern and a wireless tracking device may receive the beacon signal by tuning a receiver according to the frequency hopping pattern. In an embodiment, the modified frequency hopping pattern may include a reference frequency generated at a high redundancy pattern multiplexed with a pseudo random sequence of frequencies. In an embodiment, the packets of the beacon signal transmitted at the reference frequency may include an indication of the next frequency according to the modified frequency hopping pattern.Type: GrantFiled: February 16, 2015Date of Patent: March 1, 2016Assignee: QUALCOMM IncorporatedInventors: Catalin Lacatus, Hemish Parikh, Harleen Kaur Gill
