Publication number: 20180088624Abstract: Touch sensing can be accomplished using master/slave touch controllers that transmit drive signals to a touch surface and process sense signals including superpositions resulting from master/slave drive signals. The master/slave can drive and sense different sets of lines, respectively, of the touch surface. A communication link between master/slave can be established by transmitting a clock signal between master/slave, transmitting a command including sequence information to the slave, and initiating a communication sequence from the clock signal and sequence information. The slave can receive/transmit communications from/to the master during first/second portions of the communication sequence, respectively.Type: ApplicationFiled: December 4, 2017Publication date: March 29, 2018Inventors: Thomas James Wilson, Richard James Reeve

Patent number: 8890817Abstract: Centralized processing of touch information obtained by multiple touch sensing controllers connected to a touch sensing surface is provided. Each touch controller can obtain touch information of sense signals from different sense lines of the touch sensing surface and can store the touch information in a corresponding memory of the controller. The touch information of one or more of the touch sensing controllers can be transmitted as results data to a processor that processes all of the touch information. In some cases, prior to transfer of the results data, a determination of the validity of a sense channel can be made, and invalid channels can be excluded from the transfer.Type: GrantFiled: September 7, 2010Date of Patent: November 18, 2014Assignee: Apple Inc.Inventors: Thomas James Wilson, Richard James Reeve

Patent number: 8405617Abstract: A method and system for managing power in a computer system is disclosed. In one embodiment the method includes providing output signals from a sensor panel to a controller, wherein the controller includes a data bus and a plurality of devices communicatively coupled to the data bus; monitoring an activity level on the data bus by monitoring bus access requests by one or more of the plurality of devices; and reducing or shutting off a bus clock frequency if there is reduced or no activity on the bus for a predetermined period of time.Type: GrantFiled: January 3, 2007Date of Patent: March 26, 2013Assignee: Apple Inc.Inventors: Thomas James Wilson, Richard James Reeve

Patent number: 7622950Abstract: Dynamically configurable routing logic coupled between physical I/O ports and special purpose I/O associated with functions within a panel ASIC is disclosed that provide different routing configurations between the physical I/O ports and the special purpose I/O. In one routing configuration, any special purpose output can be coupled to one or more physical I/O ports, providing flexibility to route any functional I/O to any physical I/O port. In a second routing configuration, any input signal on a physical I/O port can be coupled to one or more special purpose inputs. In a third routing configuration, the input signals on a number of physical I/O ports can be configured to independently assert a single special purpose input for interrupt triggering. The dynamically configurable nature of the routing logic allows routing to be changed on the fly.Type: GrantFiled: January 3, 2007Date of Patent: November 24, 2009Assignee: Apple Inc.Inventors: Christoph Horst Krah, Richard James Reeve

Patent number: 4120509Abstract: A self-steering tandem bogie for the rear of an articulated vehicle. The bogie comprises a front and a rear axle which are universally attached to a pair of longitudinally extending walking beams for sliding motion thereon, affording angular variation of the axles during vehicle turning. The load of the vehicle is transferred to the bogie by a steering unit which is universally attached to the walking beams between the two axles. As the vehicle executes a turn, the steering unit rotates in the direction of vehicle turn, while the walking beams tend to maintain the straight-drive orientation. This relative movement between the steering unit and the walking beams is transmitted to the front axle by a pair of steering arms, causing the front axle to rotate in the direction of turn, and thereby facilitating vehicle turning.Type: GrantFiled: April 22, 1977Date of Patent: October 17, 1978Inventors: Richard James Reeve, Dennis Raymond Shirley
