摘要： The present invention relates to a head-mountable information processing apparatus allowing a user to hear a desired sound even if ambient sound unnecessary for the user is present. An audio input interface includes sound microphones worn in the vicinity of the user's ear, collects the ambient sound that occurs outside the head-mountable information processing apparatus, and converts the ambient sound into an input audio signal. An audio output interface, including headphones, converts a generated output audio signal for output, and emits the audio output toward the user. Based on a volume level of the input audio signal and a volume level of the output audio signal, a controller determines whether or not a state in which the ambient sound is preventing the audio for output from being heard is occurring, and based on a determination result, the controller controls a sound emission operation of the audio output interface.

摘要： An earbud set includes a first earbud and second earbud that each include a speaker and a wireless radio wirelessly coupled to a companion information handling system. At least one of the first or second earbud includes a processor, a memory device, and a magnetometer. The earbud set may include a relative mapping system to determine an earbud fixed compass orientation a front-facing assigned alignment direction for the first earbud and the second earbud and determine an angular alignment difference between the earbud fixed compass orientation and a magnetic earth field compass direction of the companion information handling system. The relative mapping system to use wireless or ultrasonic signals to determine distance from the first and second earbud to the companion information handling system. The processor uses distance measurements and a difference between the distances to determine a distance and a direction to the companion information handling system.

摘要： Systems, methods, and apparatuses for a self-locating compass for use in navigation are disclosed. The self-locating compass is operable to provide position and/or velocity without information from a global positioning system (GPS) device. The self-locating compass includes a direction finder and a Lorentz force detector. The method includes determining orientation with respect to Earth's magnetic field, measuring a Lorentz force proportional to rate of change of location with respect to the field, determining a change in location, and updating location.

摘要： A digital compass with two or more multi-axis magnetometers and a processing element to determine a heading and detect any offset error in the heading is described. One electronic device includes first and second magnetometers. The second magnetometer can be disposed at least a specified distance or co-located and offset at least a specified angle from the first magnetometer. A processing device determines a magnetic field at the electronic device using a first output from the first magnetometer, detects an offset error in the magnetic field using a second output from the second magnetometer, and reports the offset error in the magnetic field.

摘要： Roll data can be acquired from a magnetometer and an accelerometer of a towed object telemetry unit coupled to a towed object during rolls of the towed object in two or more different headings. The magnetometer can be calibrated based on the roll data. Turn data can be acquired from the magnetometer and the accelerometer during a turn of the towed object from a first heading to a second heading. The magnetometer can be further calibrated based on the turn data.
