Title
(EN) MULTICHANNEL GYROSCOPIC SENSOR
(FR) CAPTEUR GYROSCOPIQUE À CANAUX MULTIPLES
Abstract
(EN)
An electronic device may have a gyroscopic sensor. The gyroscopic sensor may produce angular velocity data in response to movement of the electronic device. The gyroscopic sensor may have a first and second parallel branches of circuitry that are configured to produce angular velocity data from microelectromechanical systems output signals. When performing functions such as gaming or navigation functions, the electronic device may use the first branch of circuitry to produce angular velocity data with a large dynamic range. When performing functions such as image stabilization operations, the electronic device may use the second branch of circuitry to produce angular velocity data that is characterized by a relatively small amount of noise.

L'invention porte sur un dispositif électronique qui peut avoir un capteur gyroscopique. Le capteur gyroscopique peut produire des données de vitesse angulaire en réponse à un mouvement du dispositif électronique. Le capteur gyroscopique peut avoir des première et seconde branches parallèles de circuiterie, qui sont configurées de façon à produire des données de vitesse angulaire à partir de signaux de sortie de système microélectromécanique. Lors de la réalisation de fonctions telles que des fonctions de jeu ou de navigation, le dispositif électronique peut utiliser la première branche de circuiterie pour produire des données de vitesse angulaire avec une large plage dynamique. Lors de la réalisation de fonctions telles que des opérations de stabilisation d'image, le dispositif électronique peut utiliser la seconde branche de circuiterie pour produire des données de vitesse angulaire qui sont caractérisées par une quantité de bruit relativement faible.
