  • STYLUS FOR CAPACITIVE TOUCHSCREEN
    Publication number: 20180120964
    Abstract: Embodiments of amplifiers and electrodes for capacitive styluses are disclosed. The amplifiers detect an input signal from a capacitive touch sensor, such as a touchscreen or touchpad, amplify and invert the signal, and emit the amplified and inverted signal to cause the capacitive touch sensor to detect a touch. The electrode sets, or tips, pair a sensing electrode and an emitting electrode, shielded from each other to limit interference, in a fine-point non-deforming configuration that improves usability over existing stylus tips.
    Type: Application

  • Battery charger device and method
    Patent number: 9859727
    Abstract: Embodiments of a battery charger and methods for operating same are disclosed. The charger has a plurality of charging pins, and a device to be charged may be plugged into the charger in multiple orientations. The charger detects the device's orientation and sets the states of its charging pins appropriately to charge the device. Optionally, the charger may have additional pins, likewise settable according to a device's orientation, for supplying power and/or communications to the device during charging.
