Filed:

Sep 11, 2012

Appl. No.:

13/610719

Inventors:

Hung A. Pham - Oakland CA, US
Hengliang Zhang - Sunnyvale CA, US

Assignee:

APPLE INC. - Cupertino CA

International Classification:

G06F 15/00
G01C 19/00

US Classification:

702145

Abstract:

Implementations are disclosed for using magnetometer measurements to estimate bias for angular rate measurements provided by an angular rate sensor (e.g., a gyro sensor). In some implementations, a bias estimator running on a device is configured to determine if the device is rotating based on the magnetometer measurements. If the device is not rotating, a dynamic bias is calculated and added to a temperature compensated static bias to provide a total angular rate measurement bias. The total angular rate measurement bias can be provided to an attitude estimation system where it is used to update an attitude (orientation) of the device. In some implementations, the angular rate measurements are used to determine if the device is oscillating according to a threshold value. If the device is not rotating and the device is oscillating according to a threshold value, the static bias is updated in a calibration table.

Abstract:

Disclosed embodiments include wearable devices and techniques for detecting cycling activities and monitoring performance during cycling. By accurately and promptly detecting the end of cycling workouts automatically, the disclosure enables wearable devices to accurately calculate user performance information when users forget to stop recording a cycling activity session. In various embodiments, cycling activity detection techniques involve a cycling speed measure that incorporates terrain gradient determined based on pressure data. In various embodiments, the cycling activity detection techniques may distinguish between a temporary stop and an intentional stop using an estimated energy expenditure.

International Classification:

H04R 1/10
H04R 29/00

Abstract:

Ear buds may have optical proximity sensors and accelerometers. Control circuitry may analyze output from the optical proximity sensors and the accelerometers to identify a current operational state for the ear buds. The control circuitry may also analyze the accelerometer output to identify tap input such as double taps made by a user on ear bud housings. Samples in the accelerometer output may be analyzed to determine whether the samples associated with a tap have been clipped. If the samples have been clipped, a curve may be fit to the samples. Optical sensor data may be analyzed in conjunction with potential tap input data from the accelerometer. If the optical sensor data is ordered, a tap input may be confirmed. If the optical sensor data is disordered, the control circuitry can conclude that accelerometer data corresponds to false tap input associated with unintentional contact with the housing.

International Classification:

H04W 68/02
H04M 19/04
G08B 6/00
H04M 1/725

Abstract:

An electronic device that provides situationally-aware alerts determines to provide an alert output (such as haptic, audio, visual, and so on) via an output device, determines a movement pattern based on one or more signals from one or more sensors indicating information relating at least to movement of the electronic device, and adjusts the alert output to account for the movement pattern. In some implementations, the electronic device may adjust the alert output by delaying the alert output. In other implementations, the electronic device may adjust the alert output by altering the alert output to be discernible despite the movement pattern based on a cadence of the movement pattern. In still other implementations, the electronic device may determine to provide the alert output in response to receiving an incoming communication and may adjust the alert output differently based on a priority associated with the incoming communication.

International Classification:

G01C 5/00

G01C 22/00

Abstract:

An electronic device may include a motion sensor for detecting movement of the electronic device and a pressure sensor for detecting changes in elevation of the electronic device. Applications that run on the electronic device such as health and fitness applications may use motion sensor and pressure sensor data to track a user's physical activity. For example, processing circuitry in the electronic device may use the motion sensor to track a user's steps and the pressure sensor to track changes in the user's elevation. The processing circuitry may determine whether the user is climbing stairs based on the user's step rate and the user's changes in elevation. When the processing circuitry determines that the user is climbing stairs, the processing circuitry may use the pressure sensor and motion sensor to track and store the number of flights of stairs climbed by the user.
