Abstract: A seamless and secure cloud to PC pointer relay allows a pointer/cursor to be moved between secure and unsecure windows while being displayed with smooth transitions and while transitioning between secure and unsecure data handling for pointer information. A secure input unit encrypts pointing device operations in the secure window. A user (host) computing device performs location calculations on encrypted data, which conceals pointing device operations in the secure window from the host operating system. The secure unit decrypts the encrypted data returned by the host operating system to determine the calculated pointer location information. The secure unit relays the calculated pointer operation information to the source of the secure window (e.g., remote cloud server) to process user interaction with the secure window while keeping the host operating system unaware of user activity in the secure window (e.g., other than position, if the host renders the pointer).

Abstract: Phishing protection utilizes a security identifier displayed in association with secure content. The identifier may be displayed separately for comparison. A security identifier may be generated by a user interface, local source, or remote source. Users may visually and/or physically confirm identifiers. An identifier may be a character string or QR code. Phishing attempts may be monitored, detected, and alerted during and outside a secure session. A device may modify images from a first computing device to a display monitor. A device interface may receive a first image from the first computing device. A detector may monitor the first image for counterfeit information. An alert generator may generate a security alert for counterfeit information. A combiner may combine with the first image, in response to a secure session, a secure image associated with a secure identifier and, in response to the detector detecting counterfeit secure information, the security alert.

Abstract: Examples are disclosed relating to using a spatial noise model to compensate for noise in a frame of touch sensor data. One example provides, on a computing device, a method comprising receiving a noise level for each sensor antenna of a set of sensor antennas of a touch sensor; for each pair of sensor antennas, determining a noise compensation ratio comprising a noise level of a first antenna compared to a noise level of a second antenna; and storing the noise compensation ratio in a spatial noise model.

Abstract: Power management logic of a multi-display touch device provides for selectively reducing a power state of a touch system within each individual display at times when the touch system of the display is inactive. The power management logic facilitates selective toggling of the touch system from a high power state to a low power state independent of a power state of other touch systems in the multi-display device, The power management logic further facilitates selective toggling of the touch system power state from the low power state to the high power state responsive to a communication received across the interlink.

Abstract: A method of synchronizing system state data is provided. The method includes executing a first processor based on initial state data during an update cycle, wherein the initial state data represents a state of the system prior to initiation of the update cycle, detecting changes in state of the system by the first processor using sensors, the changes in state being added to a record of modified state data until a predefined progress position within the update cycle, designating the modified state data as next state data, based on reaching the predefined progress position within the update cycle, and transitioning from execution of the first processor based on the initial state data to execution of the first processor based on the next state data, based on completion of the update cycle.

Abstract: A touch-screen system comprises adjacent first and second touch-screen sensors, first and second digitizers, and synchronization and return logic. Each of the first and second digitizers is coupled electronically to the respective touch-screen sensor and configured to provide a pen signal responsive to action of a pen on the touch-screen sensor. The synchronization logic is configured to synchronize the pen to the first and second digitizers and to enable pen tracking by any of the first and second digitizers conditionally, based at least partly on the first and second pen signals. The return logic is configured to expose a result of the pen tracking to an operating system of the touch-screen system.
