Publication number: 20140217945Abstract: A method and apparatus for automatic resonance detection is disclosed for a motor-driven mechanical system such as a voice coil motor (VCM) in which a resonance detector and driver are provided. The automatic resonance detector may be implemented on the same integrated circuit as the driver, and dynamically determines the natural resonant frequency of the VCM driven by the driver. The resonant frequency is determined by measuring the back electromotive force (BEMF) of the VCM, detecting the slope of the BEMF signal, and determining the resonant frequency from the slope of the BEMF signal.Type: ApplicationFiled: February 6, 2013Publication date: August 7, 2014Applicant: Analog Devices TechnologyInventors: Alan Patrick Cahill, Gary Casey, John A. Cleary, Eoin Edward English, Christian Jimenez, Javier Calpe Maravilla, Colin G. Lyden, Thomas F. Roche

Patent number: 8605053Abstract: A method and a device for detecting user input includes receiving a user input at an input arrangement of a user interface. The input arrangement has at least one piezoelectric sensor that generates an electric signal in response to the input. The electric signal is processed to determine the presence of the input. The processing may indicate the magnitude of the force of the input, in addition to the input's location. An output arrangement of the user interface generates an output in response to the processing. The output may be a haptic, audio or visual output.Type: GrantFiled: February 19, 2010Date of Patent: December 10, 2013Assignee: Analog Devices, Inc.Inventors: Mark J. Murphy, Eoin Edward English, Eoghan Moloney, Mel Conway, Gary Casey, Krystian Balicki

Patent number: 8330324Abstract: An apparatus, system and method for controlling drive patterns is disclosed. A digital engine for controlling drive patterns may include a profile controller to program characteristics of one or more drive patterns for one or more piezoelectric actuators. The digital engine may further include a register array to store profile information for the one or more drive patterns. Each drive pattern may comprise a plurality of pulses with each pulse having a slope. The digital engine may also include a digital pattern generator to generate the one or more drive patterns based upon the profile information stored in the register array. The digital engine may further include a slope shaping circuit to modify one or more signals based upon an input from the digital pattern generator.Type: GrantFiled: June 8, 2010Date of Patent: December 11, 2012Assignee: Analog Devices, Inc.Inventors: Gary Casey, Eoin Edward English, Christian Jimenez, Alberto Marinas

Patent number: 8305200Abstract: A device and method are provided to drive piezoelectric elements in haptic applications. In one embodiment, a pattern generator provides user programmable PWM waveforms to a driver. The load of the driver is an inductor in series with the piezoelectric element. The filtration of the inductor in series with the capacitance of the piezoelectric element suppresses the high-frequency components of the PWM pulse train, and recovers a value commensurate with the duty cycle of the PWM pulse train. The resulting waveform across the piezoelectric element is converted to physical motion, thereby creating a haptic effect on a user interface. Advantageously, there is reduced power loss, reduced switching induced noise, and a more haptic rich environment.Type: GrantFiled: December 2, 2009Date of Patent: November 6, 2012Assignee: Analog Devices, Inc.Inventors: Mark J. Murphy, Alan Gillespie, Eoin Edward English, Donal Geraghty, Dennis A. Dempsey

Publication number: 20120229264Abstract: The present invention provides a haptics control system that may include a driver to generate a continuous drive signal and to output the drive signal to a mechanical system on an electrical signal line, wherein the continuous drive signal causes the mechanical system to vibrate to produce a haptic effect. The haptics control system may further include a monitor, coupled to the electrical signal line, to capture a Back Electromotive Force (BEMF) signal generated by the mechanical system in the electrical signal line, to measure a BEMF signals attribute, and to transmit an adjustment signal to the driver based on the BEMF signals attribute. The driver is further configured to adjust the continuous drive signal according to the adjustment signal.Type: ApplicationFiled: August 26, 2011Publication date: September 13, 2012Applicant: ANALOG DEVICES, INC.Inventors: Enrique Company Bosch, Javier Calpe Maravilla, Santiago Iriarte, Eoghan Moloney, Krystian Balicki, Mark Murphy, Eoin Edward English, Pedro Lopez Canovas
