Patent number: 10901529Abstract: Digital signal processing circuitry, in operation, determines, based on accelerometer data, a carry-position of a device. Double-tap detection parameters are set using the determined carry-position. Double-taps are detected using the set double-tap detection parameters. In response to detection of a double-tap, control signals, such as a flag or an interrupt signal, are generated and used to control operation of the device. For example, a device may enter a wake mode of operation in response to detection of a double-tap.Type: GrantFiled: July 19, 2018Date of Patent: January 26, 2021Assignees: STMICROELECTRONICS S.r.l., STMICROELECTRONICS, INC.Inventors: Stefano Paolo Rivolta, Mahaveer Jain, Ashish Bhargava

Patent number: 10868906Abstract: A portable device includes one or more memories and travel mode control circuitry coupled to the one or more memories. The travel mode control circuitry, in operation, monitors motion data and detects a first travel state of the device based on the monitored motion data and an acceleration profile. When the first travel state of the device is detected, motion data and pressure data are monitored to detect a transition from the first travel state to a second travel state of the device. When the transition to the second travel state of the device is detected, one or more control signals are generated to cause the device to enter a first travel mode of operation.Type: GrantFiled: June 3, 2020Date of Patent: December 15, 2020Assignee: STMICROELECTRONICS, INC.Inventors: Mahaveer Jain, Mahesh Chowdhary

Publication number: 20200348136Abstract: A device including microelectromechanical systems (MEMS) sensors is used in dead reckoning in conditions where Global Positioning System (GPS) signals or Global Navigation Satellite System (GNSS) signals are lost. The device is capable of tracking the location of the device after the GPS/GNSS signals are lost by using MEMS sensors such as accelerometers and gyroscopes. By calculating a misalignment angle between a sensor frame of the device with either the movement direction of the vehicle or the walking direction of a pedestrian using the MEMS sensors, the device can accurately calculate the location of a user of the device even without the GPS/GNSS signals. Accordingly, a device capable of tracking the location of a pedestrian and a user riding in a vehicle without utilizing GPS/GNSS signals can be provided.Type: ApplicationFiled: April 30, 2019Publication date: November 5, 2020Inventors: Mahaveer JAIN, Mahesh CHOWDHARY

Patent number: 10641625Abstract: In general, the invention relates to an algorithm and process for automated and/or continuous calibration of magnetic sensor, for example such as a sensor installed in a mobile positioning system handset. According to certain aspects, the calibration process can use the normal motion of the handset such that all measurement data from the three orthogonal axes of sensor when exposed to Earth's magnetic field is collected. According to still further aspects, the process includes fitting measurement data to an ellipsoid that characterizes the actual magnetic field measurements from a magnetic sensor, so that anomalies such as hard iron effect, soft iron effect and scale factors can be extracted and/or corrected by comparison to a sphere represented by magnetic field data from a model at the sensor's location.Type: GrantFiled: August 29, 2014Date of Patent: May 5, 2020Assignee: CSR Technology Holdings Inc.Inventors: Mahesh Chowdhary, Mahaveer Jain

Patent number: 10151805Abstract: A method includes acquiring magnetic data from a magnetometer, processing the magnetic data to perform robust calibration, and generating optimum calibration parameters using a calibration status indicator. To that end, the method includes generating a calibration status indicator as a function of time elapsed since a last calibration and variation in total magnetic field in previously stored magnetic data, detecting anomalies, and extracting a sparse magnetic data set using comparison between the previously stored magnetic data and the magnetic data. Calibration parameters are generated for the magnetometer using a calibration method as a function of the magnetic data set. The calibration parameters are stored based on performing a validation and stability check on the calibration parameters, and weighted with the previously stored calibration parameters to produce weighted calibration parameters.Type: GrantFiled: December 18, 2015Date of Patent: December 11, 2018Assignees: STMicroelectronics, Inc., STMicroelectronics International N.V.Inventors: Mahaveer Jain, Mahesh Chowdhary
