Abstract: Techniques for controlling operations of a motor based on position errors are described. In an example, a user device sends an amount of electrical current to the motor to cause the motor to move. The user device also determines the motor is in position for a time interval despite the amount of electrical current. Based at least one the time interval and the amount of electrical current, the user device determines a position difference associated with a target position and a measured position of the motor during the time interval, and reduces the amount of electrical current based at least in part on the time interval.

Abstract: A roller module includes a supporting seat, a scroll wheel, a linkage rod, a torsion spring, a first magnet, a second magnet and a coil. The scroll wheel is installed on the supporting seat. The linkage rod includes a fulcrum segment, a resisting segment and an effort segment. The torsion spring is connected with the resisting segment. The first magnet is arranged between the second magnet and the effort segment. The coil is arranged around the second magnet. When the roller module is in a tactile mode, the first magnet and the second magnet are close to each other, and the torsion spring exerts a pulling force on the resisting segment. Consequently, the resisting segment is contacted with a toothed region of the scroll wheel. When the roller module is in a non-tactile mode, the resisting segment is moved away from the toothed region.

Abstract: A system uses a barometer to determine both a user interface event and a change in elevation. Portable devices are often limited by space to provide a user with features that make a product useful. The system uses the barometer to measure air pressure within a cavity of a housing of a wearable device. The cavity is enclosed by a cover that appears as a physical button. The cover is attached to the housing by a flexible seal that allows the cover to move in response to changes in air pressure or physical touch. If movement of the cover causes a change in air pressure in the cavity beyond a threshold, the change is interpreted to be a user input event. Otherwise, the change in air pressure is determined to be a change in altitude. Using a barometer to determine user input allows for a compact wearable device.
