  • Haptic feedback for UIs

    Haptic feedback for UIsHaptic feedback for UIs

    A2020-016 | Jakub Stachowski

    This invention describes a simple implementation of haptic feedback by using a few additional actuators known as ERM (Eccentric Rotating Mass) or LRA (Linear Resonant Actuators). The actuator used is a coil integrated into a flexible printed circuit board. When current is applied to this coil, a magnetic field is induced which interacts with a magnetic field generated by a magnet or with a magnetic field generated by another stationary coil. The magnet or the stationary coil are arranged on or in a rigid component. The magnetic force bends the flexible circuit board and moves the flexible part toward the rigid component until the flexible part collides with the rigid component. At the moment the flexible part collides with the rigid component, a knocking effect is generated and a haptic feedback is produced.

    Glow effects may occur on LED (Light Emitting Diode) light devices operated in an AC network – especially with sinusoidal voltage supply – when in "off" state, i.e. when the light devices are switched off and therefore should be dark.

  • TC Rotary Knob with slider Sensor

    A2015-009 | Mathew Schwind

    A rotary knob utilizing capacitive sensing to detect the movement of an indexed ring is suggested. Consumers are interested in a knob with an integrated user interface. Preferably this knob shall be rotating. Further a knob with metal look and feel is preferred, as it gives a worthy appearance.

    A2017-016 | Piotr Kijewski

    This idea suggests an optical transfer system. The optical transfer system transmits an image of a display located behind electronics of a front panel to the surface of a knob located on the front panel.

    A2015-015 | Andreas Brauchle, Simon Bihler

    A connector which is not placed correctly on a contact heats up and may catch fire. This risk is particularly high when high currents flow as is the case, for example, in electric-motor electronics.

    B2017-011 | Andre Selz

    The proposed technical solution concerns a sensor network consisting of a variety of sensors for surveillance-relevant parameters, which can be placed in a terrain and are self-networking.

    A2018-025 | Sascha Laue, Thomas Zodel, Tobias Hartmann

    This invention solves the problem of putting an appliance into demo mode, without the risk that the customer enables this mode by accident. Further it transfers and updates demo mode data to the appliance.
