Patent number: 10506068Abstract: Examples of the disclosure enable managing a user account, such that a peripheral device is configured to interact with one or more user devices associated with the user account. In some examples, a device identity associated with the peripheral device is identified, and it is determined whether the device identity is associated with a user account. Upon determining that the device identity is associated with the user account, the peripheral device is paired with a user device associated with the user account without manually pairing the peripheral device with the user device. Examples of the disclosure enable the peripheral device to interact with one or more user devices in an efficient, user-friendly manner.Type: GrantFiled: April 6, 2015Date of Patent: December 10, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Chintan M.

Patent number: 10489937Abstract: Paintbrush and liquid simulation techniques are described. In one or more implementations, input is received to perform brush strokes with a virtual paintbrush on a virtual canvas. For virtual paint on the virtual canvas, lifelike paint qualities are simulated. However, the lifelike paint qualities are simulated solely for the virtual paint that is within a region of the canvas. The lifelike paint qualities are not simulated for virtual paint located outside the region. As part of simulating the interaction between the virtual paint, the virtual paintbrush, and the virtual canvas, various parts of the simulation may be performed by different processing units. For example, bristles of the virtual paintbrush may be simulated utilizing a first processing device such as a central processing unit (CPU). A second processing unit, such as a graphics processing unit (GPU), may be employed to simulate the lifelike effects of the virtual paint.Type: GrantFiled: March 15, 2017Date of Patent: November 26, 2019Assignee: Adobe Inc.Inventors: Byungmoon Kim, Nathan A.
