    Abstract: An e-pen includes e-pen sensor electrodes (including a first and a second e-pen sensor electrode) and drive-sense circuits (DSCs) (including a first DSC and a second DSC. The first DSC drives a first e-pen signal having a first frequency via a first single line coupling to the first e-pen sensor electrode and simultaneously senses, via the first single line, the first e-pen signal. Based on e-pen/touch sensor device interaction, the first e-pen signal is coupled into at least one touch sensor electrode of the touch sensor device. The first DSC process the first e-pen signal to generate a first digital signal representative of a first electrical characteristic of the first e-pen sensor electrode. Similarly, the second DSC drives a second e-pen signal having a second frequency via a second single line coupling to the second e-pen sensor electrode and simultaneously senses, via the second single line, the second e-pen signal.

  • Patent number: 10775632
    Abstract: A system and method for augmented reality (AR) visor light security employs an optical shutter to mitigate illumination escaping from a see-through waveguide holographic AR display incorporated with a ballistic visor. Based on a security level of the environment, the user selects an auto or manual mode to command a full transmittance, partial transmittance, or full occlusion automatically set via ambient sensors within the system to remove glare and better view a contrast of AR images presented on the waveguide. In high security, the user relies solely on enhanced vision systems display on the waveguide for situational awareness and desire a full bi-directional occlusion of the optical shutter allowing zero emissions from the visor. An optical shutter sensor continuously measures the current level of occlusion to ensure it matches a commanded occlusion and if not, the system disables the display source and removes the occlusion.
