  • Systems and methods for simulating a tympanic membrane
    Patent number: 11741856
    Abstract: Disclosed herein is a device for modeling properties of an ear. The device includes an artificial tympanic membrane and a housing coupled to the artificial tympanic membrane. The housing defines an interior portion coupled to an interior surface of the artificial tympanic membrane. The interior portion has an adjustable volume or an adjustable type of fluid and an adjustable gas pressure. Adjustment of the volume or type of fluid and the gas pressure changes a membrane movement to produce selected movement properties according to a mobility scale.
    Type: Grant

  • Keyboard appliance for touchscreen
    Patent number: 8988355
    Abstract: A keyboard activates areas of a touchscreen according to user interaction with the keyboard. A discharge circuit provides a discharge path for altering the electrostatic field of the touchscreen. Such discharge circuit excludes the user's finger (or stylus). Instead of grounding to the user, a ground plane in varying embodiments may be contained within the keyboard, or be formed at least in part by by the case of the keyboard, the case of the host device, or the ground plane of the host device. The keyboard includes an electrical ground member to absorb the capacitive discharge and/or conduct such discharge to the ground plane.
