    Abstract: This application relates to illuminated dome switches and a dome switch assembly having a first contact carried by a switch base and a dome shaped structure coupled to and supported by the switch base, the dome shaped structure comprising a material that is flexible and capable of internally transmitting visible light. The switch assembly can include a second contact coupled to the dome shaped structure and arranged opposite the first contact, and a light source configured to emit visible light, the light source in optical communication with the dome shaped structure such that at least some of the visible light emitted by the light source passes into the material and is subsequently emitted by the material in a generally uniform manner.

    CPC classification number: G06F3/043

    Abstract: Input devices can employ ultrasonic touch sensing capabilities that allow user inputs to be detected through conductive materials, such as metal enclosures. The ultrasonic touch sensing can include generation of ultrasound signals with a piezoelectric layer. The ultrasound signals can be reflected when a user or other object is in contact with a housing, and the reflected signal can be detected by the same piezoelectric layer that produced the ultrasound signal. Such a piezoelectric layer can include a piezoelectric polymer, such as polyvinylidene fluoride (PVDF). An array of electrodes distributed on opposing sides of the use of electric layer can be operated to generate ultrasound signals and detect reflected signals. Such an input device can be operated in conjunction with a conductive (e.g., metallic) housing, conform to a variety of shapes, and be compact and lightweight

    Abstract: According to some embodiments, an accessory device for interacting with an electronic device having a touch sensitive surface, is described. The accessory device can include a housing having walls suitable for carrying a processor capable of providing instructions and an interface unit extending through an opening at a distal end of the housing, where the interface unit is capable of interacting with the touch sensitive surface. The accessory device can further include a sensor in communication with the processor and the interface unit, where the sensor is capable of (i) detecting a stimulus generated by the interaction between the interface unit and the touch sensitive surface, and (ii) responding by providing a feedback parameter to the processor that responds by providing a feedback instruction. The accessory device can further include a feedback component that responds to the feedback instruction by transmitting a feedback force to the walls of the housing.

    Abstract: A stylus can include a housing and a tip. A force-sensing system can detect movement of the tip relative to the housing when a force is applied to the tip. A haptic feedback system can move the tip relative to the housing, for example by inducing a magnetic field in magnetic elements connected to the tip and the housing. The haptic feedback can be used to render texture sensations to simulate drawing on a textured surface with the stylus. As such, the same tip that is used to provide inputs can receive haptic feedback during use. The user can continue to use the tip for input even as haptic feedback is also being applied to the tip.

    Abstract: An input device, such as a stylus, can include a piezoelectric device for providing haptic feedback and/or detecting user input. The piezoelectric device can be coupled to an inner surface of a housing of the stylus. The piezoelectric device can provide haptic feedback with a force to the housing when an electric voltage is applied to the piezoelectric device. The haptic feedback can provide information to the user relating operation of the stylus with an external device. The piezoelectric device can also produce an electric voltage when an input force is applied to an outer surface of the housing and transmitted to the piezoelectric device. The electric voltage can be used to detect tactile input from a user.
