    Abstract: An input knob for use with a touch screen device includes stationary and moveable members. The stationary member adheres to a touch screen of the device. The moveable member moves relative to the stationary member, and is secured to the surface via the stationary member. The moveable member produces touch events on the touch surface as bits of data in response to movement of the moveable member. The moveable member may include a rotary encoder. The stationary member may include conductive pads in contact with the surface and in selective contact with a conductive mass of the moveable member. The moveable member may be ring-shaped, removeable and repositionable with respect to the surface, and/or constructed of or coated by dielectric materials. The knob may lack a direct hardwired electrical connection to or through the surface. A display system includes the touch screen device and knob.

  • Patent number: 10942379
    Abstract: A bi-modal dimming mirror includes a display and a switchable mirror configured to vary in transmissivity in response to a dimming control signal, which includes one or more of an LCD voltage, a rotator control signal, and/or a polarizer control signal. The bi-modal dimming mirror includes a visible segment overlying the display panel and a sample segment for calibrating the transmissivity or the reflectivity of the switchable mirror. A light source projects a light beam through the sample segment, which is measured by a light sensor. A liquid crystal cell changes polarization of light passing therethrough in response to application of an LCD voltage. In some embodiments, an active absorptive polarizer varies in absorption of polarized light in response to a polarizer control signal. An active polarization rotator varies rotation of polarized light in response to a rotator control signal.

  • Patent number: 10838523
    Abstract: A touch screen device includes a display screen having a touch surface, an input knob, and a microcontroller programmed to execute a method. The knob has a stationary member with conductive base pads facing the surface and a moveable member. The knob lacks a direct electrical connection to the surface. The microcontroller receives encoder signals as the moveable member moves with respect to the stationary member, with the signals being indicative of discrete touch events between the moveable member and the screen, e.g., via an intervening switch. The microcontroller processes the encoder signals to determine a direction of movement of the knob, and derives a true position of a center point of the knob using a position of each of the base pads. The microcontroller then controls an operation of the touch screen device.
