Abstract: Devices and techniques to decrease latency in rendering a line or other feature on a display device responsive to input on a touch sensor are described. A touch sensor may detect a touch input with the touch sensor. Touch coordinates indicative of the touch input on the touch sensor are determined. The touch coordinates are mapped to display coordinates associated with the display device. Based on the display coordinates, an operating system kernel may generate a feature, such as a line, for presentation on the display.

Abstract: Techniques and systems are provided for facilitating secure pairing of a client device with a remote device using a inductive pickup coil in the client device and an intermediate hearing-aid-compatible (HAC) mobile device. Credentials stored in or accessible to the mobile device may be encoded in an magnetic HAC signal in the audio frequency spectrum and communicated to the client device through inductive coupling with the inductive pickup coil in the client device. The client device may then use the credentials to gain access to the remote device. In some implementations, the mobile device may cease broadcasting the magnetic signal upon receipt of an indication that the client device has gained access to the remote device.
