Abstract: A device (120) including microelectromechanical systems (MEMS) sensors are used in dead reckoning in conditions where Global Positioning System (GPS) signals or Global Navigation Satellite System (GNSS) signals are lost. The device (120) 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 forward axis of a sensor frame of the device and a forward axis of a vehicle (110) frame using the data received from the MEMS sensors, the device can accurately calculate the location of a user or the vehicle of the device even without the GPS/GNSS signals. Accordingly, a device capable of tracking the location of the user riding in the vehicle in GPS/GNSS signals absent environment can be provided.

Abstract: A system may include a motion sensor (102) configured to generate a motion signal in response to a movement of an electronic device (101), and at least one feature detection circuit (104-1, 104-2, 104-3) configured to determine at least one metric based on the motion signal. The system may further include a classifying circuit (108) configured to determine whether the electronic device (101) is in contact with a human body based on the at least one metric.

Abstract: A method uses a device including microelectromechanical systems (MEMS) sensors in vehicle and pedestrian 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 method capable of tracking the location of a pedestrian and a user riding in a vehicle without utilizing GPS/GNSS signals can be provided.

Abstract: A method and apparatus for classifying a spatial environment as open or enclosed are provided. In the method and apparatus, one or more microphones (102) detect ambient sound in a spatial environment and output an audio signal representative of the ambient sound. A processor (104) determines a spatial environment impulse response (SEIR) for the audio signal and extracts one or more features of the SEIR. The processor classifies the spatial environment as open or enclosed based on the one or more features of the SEIR.

Abstract: A portable device includes one or more memories (104) and travel mode control circuitry (112) coupled to the one or more memories. The travel mode control circuitry, in operation, monitors motion data to detect a first travel state of the device. When the first travel state of the device is detected, motion data are monitored to detect a transition from the first travel state to a second travel state of the device. The first travel state is different from the second travel state. 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.

Abstract: A portable device includes one or more memories (104) and travel mode control circuitry (112) coupled to the one or more memories. The travel mode control circuitry, in operation, monitors motion data and temperature data to detect a first travel state of the device. 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.
