摘要： A haptic engine includes a haptic actuator having a double-wound driving coil in which the two windings are connected with each other either in series or in parallel. By using the double-wound driving coil in which the two windings are connected with each other in series, an instant back EMF voltage induced in either of the two windings can be determined without having to measure in real time a resistance of the corresponding winding, and without having to sense a driving current through the double-wound driving coil. By using the double-wound driving coil in which the two windings are connected with each other in parallel, an instant back EMF voltage induced in either of the two windings can be determined without having to measure in real time a resistance of the corresponding winding.

摘要： A haptic system includes a haptic engine in which a reluctance motor is driven by a driver controller operated in conjunction with an impedance-estimator that uses amplitude-modulated calibration signals. An enveloped-calibration signal is superimposed on a haptic-drive signal to quickly, and accurately, estimate the driving coil's impedance, while minimizing power penalty.

摘要： An electronic device includes a housing defining an aperture. An input device extends through the aperture and has a user input surface external to the housing. An inertial actuator is mechanically and fixedly coupled to the input device and positioned within the housing. A mechanical wave dampener provides mechanical wave dampening between the input device and the housing. The electronic device enables haptic feedback to be provided locally to the input device. In some cases, the mechanical wave dampener may dampen shaking of the input device with respect to the housing by at least an order of magnitude.

摘要： A haptic engine includes a gap-closing actuator having a double-wound driving coil in which the two windings can be activated with two driving sources, respectively. Or, the two windings double-wound driving coil can be activated with a single driving source when the two windings are connected with each other either in series or in parallel. By using the double-wound driving coil in the gap-closing actuator as described, an instant inductance of either of the two windings can be determined without having to measure in real time a resistance of the corresponding winding.

摘要： A head-mountable device can include a crown module that receives input from a user and provides localized haptic feedback to the user. A magnetic element coupled to a crown can be moved by inducing magnetic fields, and the position and/or movement of the magnetic element can be detected to provide closed-loop control of the induced magnetic fields. The haptic feedback can be effectively perceived by the user at the crown without causing the entire head-mountable device to vibrate against the head and/or face of the user.

摘要： A haptic engine includes a linear resonant actuator having a double-wound driving coil which is used for sensing a back electromotive force (EMF) voltage independently of the coil resistance, thus minimizing the back EMF voltage's sensitivity to temperature.
