Abstract: A modular electronic device system that can include a computing device in electronic communication with an input device. Various types of sensor contained in either or both of the computing device and input device are used to determine orientation and hinge angle between the computing device and input device. Input settings can be changed according to the data from the various sensors. The input device can also include an elongated tail that is configured to attach to the computing device. The elongated tail can allow multiple physical configurations for ease of use.

Abstract: A stylus input device can allow a user to interface with an external electronic device. The stylus can provide an additional or alternative input to the external electronic device in response to a user applying a compressive force to the device housing. The stylus can include multiple sensors to provide a signal in response to the compressive force applied to the stylus.

Abstract: An input device such as a stylus for providing input to a touch-sensitive surface with reduced sensitivity to leakage current variations over temperature is disclosed. A passive stylus may include one or more diodes in parallel with one or more bleed resistors. The non-linear load of the diode and resistor network can be operative to provide a stylus electric field in response to a stimulation signal from an electronic device that can be capacitively coupled to, and sensed by, the electronic device. The signal sensed by the electronic device can be a function of the total leakage current, which can vary greatly as a function of temperature and frequency. In order to improve performance, the diode and resistor network, including the bleed resistor(s) and diodes within that network, can be selected and/or designed to provide a reduced variation in the leakage current and more accurate stylus detection.

Abstract: Touch-based input devices, such as a stylus, can receive tactile input from a user. The tactile input functions can be performed by a touch sensor, such as a capacitive sensing device. A touch sensor can be integrated into a stylus in a low profile form. Tactile input can be received at the user's natural grip location. Furthermore, the stylus can effectively distinguish between tactile inputs from a user and disregard sustained tactile inputs that are provided while the user simply holds the stylus at the user's natural grip location.

Abstract: Embodiments describe a receiving element that includes a ferromagnetic structure axially symmetrical around a central axis disposed along a length of the ferromagnetic structure. The ferromagnetic structure includes a groove region defining two end regions on opposing sides of the groove region, where the groove region has a smaller length than the two end regions. The receiving element also includes an inductor coil wound about the groove region of the ferromagnetic structure and in between the two end regions.

Abstract: Disclosed herein is an input device having variable make points. More specifically, the various embodiments described herein are directed to an input device having a key, a first button member and a second button member. A dielectric may be positioned between the first button member and the second button member. The key is also associated with a capacitive sensor that is configured to determine a change in capacitance as a distance between the first button member and the second button member changes.
