    Abstract: A stylus device is disclosed that provides a low power and low latency methodology of detecting a touch down event. In an aspect, the stylus device monitors an output of a pressure sensor of the stylus device using an analog comparator, a low power consumption component. When the output of the pressure sensor is greater than a first threshold value, thus indicating physical contact between the tip of the stylus device and a surface, the stylus device determines the output of the pressure sensor using an analog-to-digital converter, a higher power consumption component, to obtain a more accurate measurement of the pressure detected by the pressure sensor. When the output of the pressure sensor is less than a second threshold value, for example, indicative of non-use, the stylus device reverts back to monitoring the output of the pressure sensor using the analog comparator.

    Abstract: A stylus device is disclosed that is capable of changing its output so that it can communicate and function with a multitude of touch controllers of a computing device. In an aspect, the stylus device receives a message including the configuration information from the computing device. The configuration information may include an encoding scheme corresponding to a format for encoding data to be sent to the computing device and an operating frequency. The stylus configures itself in the encoding scheme, and communicates with the computing device using the encoding scheme. For example, the stylus device may encode data using the encoding scheme and send the data at the operating frequency.

    Abstract: Systems, methods, and devices for monitoring use of a tip of a stylus, determining an amount of wear of or life remaining in the tip, and notifying a user when to replace the tip are disclosed. The tip should be replaced to avoid an abrasive material of the tip from being exposed and contacting a touch screen or other surface of a computing device to avoid scratching or otherwise damaging the touch screen or other surface of the computing device. The computing device or the stylus device may perform one or more of the monitoring, determining, or prompting steps.

    Abstract: A stylus device is disclosed that is adapted to change its operating frequency to accommodate for a changing noise environment. In an aspect, the stylus may communicate with a computing device using a first frequency. However, when a different frequency having a better signal to noise ration than the first frequency is available, the computing device may send a message to the stylus device to switch to a second frequency. For example, the stylus device may receive a message from the computing device including an indication to communicate with the computing device on the second frequency. The stylus device may configure itself to operate at the second frequency and communicate with the computing device using the second frequency.

    Abstract: A stylus device is disclosed that enables a computing device to communicate to the stylus device using a capacitive link. In an aspect, the stylus device detects a change in an electric field generated by the computing device. A message including data is received from the computing device via the change in the electric field. The message may include an identifier corresponding to a data encoding scheme to be used for sending data to the computing device. Based on the identifier, the stylus device may configure itself to operate using the data encoding scheme.
