Patent number: 10031598Abstract: An adjustable effective electrode surface area stylus configured to operate with a capacitive touch sensitive device and coordinate detection method therefor is provided. The stylus comprises an electrode structure comprising a main electrode segment, a sub-electrode segment, a shielding, a switch, and a processing system. The main electrode segment has a main effective electrode surface area and the main electrode segment and sub-electrode segment together form an adjusted effective electrode surface area. The processing system drives the electrode structure to output one stimulation signal having one frequency and a flag and adjust between the output of a main projection of the main electrode surface area having a main central point and an adjusted projection of the adjusted electrode surface area having an adjusted central point. The main central point and adjusted central point projected from the electrode structure is used to calculate tilt and orientation of the stylus.Type: GrantFiled: June 16, 2017Date of Patent: July 24, 2018Assignee: Adonit Co., Ltd.Inventors: Jasper Li, Reinier Leopold Bloem

Patent number: 10025403Abstract: Stylus communication channels are described. In implementations, a stylus includes multiple separate and distinct communication channels used to detect the stylus, resolve positions of the stylus and a user relative to a computing device, and exchange data with the computing device (e.g., transmit and receive communications). The stylus may include a first electrode arranged in a tip portion is and a second electrode arranged in a grip area configured to form different corresponding communication channels with the computing device through the tip and through the grip area and a user's hand/body, respectively. A processing system of the computing device, such as a CPU or microcontroller, implements a stylus control module configured to analyze signal patterns derived from signals communicated the first electrode and second electrode and detect the stylus and/or resolve positions of the stylus and a user relative to the computing device based on the analysis.Type: GrantFiled: July 25, 2016Date of Patent: July 17, 2018Assignee: Microsoft Technology Licensing, LLCInventors: On Haran, Eliyahu Barel

Patent number: 10028137Abstract: Various embodiments relating to exchanging a cryptographic key between a display device and an input device via electrostatic communication are disclosed. In one embodiment, an interactive communication device includes one or more electrodes and a radio transceiver. The one or more electrodes may be excited to capacitively couple with one or more electrodes of a proximate communication device so as to capacitively send a cryptographic key from the interactive communication device to the proximate communication device. The radio transceiver may be configured to communicate with a radio transceiver of the proximate communication device via a radio channel. The interactive communication device may be configured to subsequently exchange encrypted communications with the proximate communication device over the radio channel. The encrypted communications may be encrypted using the cryptographic key.Type: GrantFiled: September 11, 2017Date of Patent: July 17, 2018Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventor: Jonathan Westhues
