Abstract: A system that generates a haptic effect using an Eccentric Rotating Mass (“ERM”) actuator determines a back electromotive force (“EMF”) of the ERM actuator during operation of the device and receives a haptic effect signal including one or more parameters, where one of the parameters is a voltage amplitude level as a function of time. Based on the determined back EMF, the system determines if the ERM actuator is spinning and varies the voltage amplitude level based on the back EMF to generate a varied haptic effect signal, where the varying includes, when the ERM actuator is determined to be spinning, reducing the voltage amplitude level compared to when the ERM actuator is determined to not be spinning. The system then applies the varied haptic effect signal to the ERM actuator.

Abstract: A signal associated with multiple haptic effects is received, each haptic effect from the multiple haptic effects being associated with a time slot from multiple time slots. Each haptic effect from the multiple haptic effects is associated with an effect slot from multiple effect slots at least partially based on the time slot associated with that haptic effect. An output signal is sent for each effect slot from the multiple effect slots, when the associated haptic effect is scheduled for its time slot.
Abstract translation: 接收与多个触觉效果相关联的信号，来自多个触觉效果的每个触觉效果与来自多个时隙的时隙相关联。 来自多个触觉效果的每个触觉效果至少部分地基于与该触觉效果相关联的时隙与来自多个效果时隙的效果时隙相关联。 当相关的触觉效果被调度为其时隙时，从多个效果时隙为每个效果时隙发送输出信号。

Abstract: A method of playing media on a device includes initiating the playing of audio/video (“A/V”) media on the device, and then identifying the A/V media. The method further includes selecting a pre-defined haptic track that corresponds to the identified A/V media, and playing the selected pre-defined haptic track in synchrony with the playing of the A/V, where the playing of the selected pre-defined haptic track generates haptic effects on the device.

Abstract: A haptically-enabled system retrieves a haptic effect definition in response to a request for a haptic effect and receives a power consumption management mode. The system modifies the haptic effect definition based at least in part on the power consumption management mode and converts the modified haptic effect definition into a haptic effect signal. The system then applies the haptic effect signal to a haptic output device.

Abstract: A haptic actuator comprising a base and a haptic transducer at least partially suspended by the base. The haptic transducer comprises a substrate and a smart material operably connected to the substrate. The smart material has resonance in response to an electrical signal having a determined frequency, and the resonance causes the haptic transducer to vibrate and deliver a haptic effect.

Abstract: A method for synchronizing haptic effects with at least one media component in a media transport stream includes identifying a series of video frames containing imaging information and/or a series of audio frames containing sound information in the media transport stream; identifying a series of haptic frames containing force feedback information in the media transport stream; and synchronizing the force feedback information in response to the imaging information and/or sound information.
