| 20100277429 | OPERATING A TOUCH SCREEN CONTROL SYSTEM ACCORDING TO A PLURALITY OF RULE SETS - An electronic device comprises a display screen configured for displaying images, a touch sensor configured to detect user input in a sensing region, a host processing system and a touch screen control system. The touch screen control system comprises control circuitry and a memory configured for holding rules. The control circuitry is configured for updating the display screen in response to image data from the host processing system and for operating according to a first set of rules held in the memory. The control circuitry is also configured, in response to receiving an indication from the host processing system, for switching from operating according to the first set of rules to operating according to a second set of rules. | 11-04-2010 |
| 20100277505 | REDUCTION IN LATENCY BETWEEN USER INPUT AND VISUAL FEEDBACK - A system comprising a display screen configured for displaying images, a touch sensor having a sensing region, a host processing system and a touch screen control system. The touch screen control system comprising touch sensor control circuitry configured to operate the touch sensor and display control circuitry configured to operate the display screen. The display circuitry comprising a first memory configured to hold a primary image and a second memory configured to hold a secondary image and display refresh circuitry. The display refresh circuitry configured to update the display screen, and in response to the user input and without requiring intervention by the host processing system, generate a blended image comprising the primary image and the secondary image, and update the display screen with the blended image. | 11-04-2010 |
| 20110001703 | CAPACITIVE MOUSE - A pointing device some or all of whose elements are made from capacitive sensors.

| 20110277030 | SYSTEM AND METHOD FOR AUTHENTICATION OF INPUT DEVICES - Systems and methods are provided for authenticating an input device subsystem for operation with a host. One method includes storing a table comprising challenges and a plurality of values indicative of authentic responses to the plurality of challenges. A selected challenge is then communicated between the input device subsystem and the host. A challenge response is derived based on the selected challenge and a hashing algorithm, and the challenge response is communicated between the input device subsystem and the host. The challenge response and one or more of the values is used to determine whether the challenge response is authentic. Functionality of the input device subsystem with the host is selectively enabled if the challenge response is authentic. | 11-10-2011 |
