    Abstract: A stylus pen that can be used as an input device to a digitizer associated with a computer screen on a computing device, such as a computer, mobile device, tablet, etc. The stylus pen can include an end cap that has multiple pressure thresholds for implementing different user-input commands. To detect the pressure being applied to the end cap, the cap is movable relative to a stylus pen body so as to move a plunger in proximity or contact with a mechanical switch. The mechanical switch is a single-action switch that is converted to a dual-action switch by using the electrical conductivity of the switch to detect an electrical coupling between a plunger and the switch. The electrical coupling can be in the form of a capacitive coupling or a direct electrical connection. Further pressure can be detected through actuation of the mechanical switch.

    Abstract: A computing device is provided, comprising a processor configured to receive a set of measurements of a vector x of acoustic data, including noise, interference, and a signal of interest. The processor may express x in a frequency domain discretized in a plurality of intervals. For each interval, the processor may generate an estimate Ŝx of a covariance matrix of x. For each Ŝx, the processor may use acoustic imaging to obtain an estimate Ŷ of a spatial source distribution. For each Ŷ, the processor may remove the signal of interest to produce an estimate Ŵ of a noise and interference spatial source distribution. For each Ŵ, the processor may generate an estimate Ŝn of a noise and interference covariance matrix. The processor may generate a beamformer configured to remove noise and interference from the acoustic data, wherein the noise and interference at each frequency are identified using Ŝn.

    Abstract: Various methods and systems for authenticating and identifying stylus devices are described herein. In one example, a method includes receiving a value generated by the stylus device during an initialization stage. The method includes receiving a code generated from the stylus device during an authentication stage. The method also includes cryptographically authenticating an author of digital ink corresponding to the stylus device on a computer device based in part on the value and the received code.

    Abstract: Individual clock adjustments between electronic devices are typically based around a round-trip time (RTT) measurement of the reference message between initiating and the receiving devices. With increasing expectations of clock synchronization accuracy, as well as widespread use of wireless data networks, the presently disclosed technology provides a dedicated clock synchronization network that yields a fixed delay between hops and within associated devices of a dedicated clock synchronization network. By accounting for the known delays between hops and within associated devices of the dedicated clock synchronization network, better clock synchronization accuracy can be achieved than prior art techniques that estimate latency based on an RTT measurement.

    Abstract: An apparatus for tracking eye gaze includes a capacitive sensor array having a plurality of capacitive sensors. The capacitive sensor array is configured to detect eye movement based at least on a proximity of the plurality of capacitive sensors to a part of an eye of a user (e.g., a bulge in the cornea). A frame of the apparatus is configured to be worn on a head of the user and configured to support the capacitive sensor array positioned in front of the eye. A control circuit of the apparatus is configured to receive signals from the capacitive sensor array. A body electrode of the apparatus is positioned on the frame and electrically connected to the control circuit, the body electrode configured to establish an electrical connection with a body of the user. A conductive line of the apparatus connects the body electrode to the control circuit.

    Abstract: An autonomous haptic stylus provides tactile feedback to a user writing or drawing on a smooth, uniform, touch-sensitive, glass display screen of a tablet, laptop computer, credit card point of sale device, or other device allowing a user to write or draw thereon. The stylus has an electrostatic detection sensor or a force/pressure sensor, which allows the stylus to detect certain characteristics of the display screen and to autonomously determine the position and/or velocity of the stylus on the display screen based on those characteristics. The position and/or velocity can be used to tailor the tactile feedback to the user. A display screen digitizer that provides driving signals for the row and column electrodes of a touch-sensitive display screen can be modified to transmit row and column information over the electrodes to allow a stylus to determine its position.
