  • Patent number: 9836152
    Abstract: The single layer compressive substrate force sensor may include electrode patterns formed directly on a first side and second side of the compressive substrate. At least some of the electrode patterns are configured to provide a change in capacitance proportional with a compressive force applied to at least one of the electrode patterns, which compresses the compressive substrate. The single layer compressive substrate force sensor may include a first top electrode and a second top electrode pattern separated by an insulator to void contact between the electrode patterns. In operation, the first top electrode pattern and the second top electrode pattern are configured to provide projective capacitance, and thus provide detection of light touches or hover actions by an object.

  • Patent number: 9664577
    Abstract: A force-sensitive resistor (FSR) assembly includes first and second electrically insulative substrates. The first substrate includes a first top surface and a first bottom surface. The second substrate includes a second top surface and a second bottom surface. The first substrate is positioned such that the first bottom surface is disposed facing the second top surface. The FSR assembly also includes thermoset ink disposed between the first substrate and the second substrate.

  • Patent number: 9520036
    Abstract: A device includes a haptic actuator to generate mechanical force stimuli in accordance with a triggering event. A haptic control system includes an accelerometer to measure the haptic response of the device. Signaling from the accelerometer is analyzed in view of an intended haptic response. A control signal may be modified in view of the analysis to correct out-of-tolerance conditions of the haptic response. This correction may occur in real time or near-real time. Component aging, shifting device performance, or other factors may be compensated for and user expectations satisfied accordingly.

  • Patent number: 9448613
    Abstract: A voltage control circuit in an electronic device receives an actuator identification signal from a personality module of an actuator in the electronic device. The voltage control circuit determines, based on the actuator identification signal, an operating voltage for the actuator and providing a drive signal at the operating voltage to the actuator.

  • Patent number: 9195343
    Abstract: An FSR assembly includes one or more active areas configured to respond to incident force by changing resistance. The FSR assembly also includes a test area constructed from the same FSR material as the active area(s), but for which the resistance remains substantially constant despite incident force on the assembly.

  • Patent number: 9165318
    Abstract: Described are methods and systems of providing an augmented experience on a user device to facilitate user interaction with one or more virtual items. An augmented image comprising an actual object and a virtual item is generated and presented in a user interface. The user interface allows the user to lock a relative position of the virtual item as presented, such that the user may appear to “move” the virtual item. The user interface may also provide sizing information of the virtual item relative item to the actual object.
