High-Order Hybrid Actuator Controller

View page
US Patent:
7489472, Feb 10, 2009
Filed:
Jan 24, 2007
Appl. No.:
11/657161
Inventors:
Mirmehdi L. Abrishamchian - Shrewsbury MA, US
Travis Hein - Holliston MA, US
Jihao Luo - Shrewsbury MA, US
Assignee:
Maxtor Corporation - Longmont CO
International Classification:
G11B 5/596
US Classification:
360 7809, 360 7804
Abstract:
A method of providing a control output by selecting a controller to an actuator is discussed. A first controller having an estimator-compensator architecture is selected if the actuator is in a settle stage. A second controller having an architecture other than that of the first controller is selected when the actuator is in a track follow stage. The control output is provided from the selected controller to the actuator. The control output is indicative of the control signal.

Stability Margins And Error Recovery In Servo Control Systems

View page
US Patent:
7602572, Oct 13, 2009
Filed:
Feb 21, 2007
Appl. No.:
11/709184
Inventors:
Mirmehdi L. Abrishamchian - Shrewsbury MA, US
Travis Hein - Holliston MA, US
Assignee:
Seagate Technology LLC - Scotts Valley CA
International Classification:
G11B 5/596
G11B 21/02
US Classification:
360 75
Abstract:
Adjusting a servo control system includes identifying a gain crossover frequency for the servo control system, generating a sensitivity function for the servo control system, measuring a sensitivity peak in the sensitivity function, comparing a frequency of the sensitivity peak to the gain crossover frequency, and adjusting the servo control system in response to the comparison of the frequency of the sensitivity peak to the gain crossover frequency.

Diffuser For Reducing Fluid Velocity Near Disk Surfaces In A Rotating Storage Device

View page
US Patent:
6788493, Sep 7, 2004
Filed:
Dec 10, 2002
Appl. No.:
10/316417
Inventors:
Shankar Subramaniam - Shrewsbury MA
Edward G. Acciardi - Grafton MA
Roger Burhans - Worcester MA
Travis Hein - Holliston MA
Gary Walker - Sherborn MA
Assignee:
Maxtor Corporation - Longmont CO
International Classification:
G11B 1702
US Classification:
360 9702, 360 9703
Abstract:
A disk drive includes a drive housing, one or more rotating storage disks, each having a storage surface, and a fluid diffuser. The fluid diffuser includes one or more stationary diffuser wings, each having a wing surface positioned near the storage surface. One or more of the diffuser wings can extend between two of the storage disks. The diffuser wing includes a surface deviation that disrupts the fluid flow over the wing surface that is caused by the rotating storage disk. The surface deviation can include an indentation in the wing surface or can extend from the wing surface toward the storage surface. In still another embodiment, the surface deviation includes an aperture that extends through the diffuser wing. Further, the fluid diffuser can include a plurality of surface deviations that are positioned along the wing surface. Further, a portion of the surface deviation can form an angle with the wing surface that is greater than approximately 0 degrees and less than approximately 180 degrees.

Road Noise-Cancellation System Responsive To Entertainment Audio

View page
US Patent:
20230102460, Mar 30, 2023
Filed:
Dec 6, 2022
Appl. No.:
18/062315
Inventors:
- Framingham MA, US
Rohan Rohilla - Boxborough MA, US
Travis L. Hein - Holliston MA, US
Assignee:
Bose Corporation - Framingham MA
International Classification:
H04R 3/02
Abstract:
A vehicle-implemented, adaptive noise-cancellation system responsive to entertainment audio is provided. The noise-cancellation system uses reference signal from a reference sensor, such as an accelerometer, to generate a noise-cancellation signal to destructively interfere with road noise in the vehicle cabin. A first set of entertainment audio thresholds triggers the system to enable or disable adaptation of an adaptive filter of the noise-cancellation system. A second set of entertainment audio thresholds triggers the system to enable, attenuate, or disable the noise-cancellation signal. As the entertainment audio increases, the system first disables the adaptation of the adaptive filter, then attenuates the noise-cancellation signal, then completely disables the noise-cancellation signal. Conversely, as the entertainment audio decreases, the system first enables the noise-cancellation signal, then reduces the attenuation (thereby increasing the amplitude) of the noise-cancellation signal, and then enables the adaptation of the adaptive filter.

Seat System For A Vehicle

View page
US Patent:
20190283634, Sep 19, 2019
Filed:
Mar 16, 2018
Appl. No.:
15/769146
Inventors:
- Woburn MA, US
Lawrence D. Knox - Hopkinton MA, US
Travis Lee Hein - Holliston MA, US
Steven N. Brown - Hopkinton MA, US
Brian Alexander Selden - Concord MA, US
Assignee:
ClearMotion Acquistion I LLC - Woburn MA
International Classification:
B60N 2/39
B60N 2/02
B60N 2/50
Abstract:
A seat system for a vehicle includes a seat having a seat bottom on which a person can sit. An intermediate support structure is secured to the seat and the vehicle which allows the seat to rotate relative to the vehicle. An actuator can interact with the seat to cause the seat to rotate relative to the vehicle. The combined motion of the vehicle relative to the earth and the seat relative to the vehicle results in motion of the seat moving about a virtual pivot point. A user control is provided for adjustment of the location of the virtual pivot point.

Controlling Active Isolation Platform In A Moving Vehicle

US Patent:
20180290567, Oct 11, 2018
Filed:
Mar 30, 2018
Appl. No.:
15/941646
Inventors:
- Woburn MA, US
Travis Lee Hein - Holliston MA, US
Assignee:
ClearMotion Acquisition I LLC - Woburn MA
International Classification:
B60N 2/39
B60N 2/10
B60N 2/02
Abstract:
Systems and methods for actively isolating a payload from a disturbance. In one example, a seat system for a vehicle includes a seat, a support structure that allows the seat to move about an axis of a pivot, a first sensor positioned to detect movement of the vehicle, a second sensor positioned to detect lateral acceleration of the pivot, an actuator configured to move the seat, and a controller configured to receive a first signal from the first sensor and a second signal from the second sensor, generate a command signal based at least on the first and the second signal to instruct the actuator to position the seat at a desired command angle, wherein the controller is configured to correct the command signal for lateral accelerations caused by steering the vehicle, and provide a force command to the actuator to move the seat at the desired command angle.

Seat System For A Vehicle

US Patent:
20180222359, Aug 9, 2018
Filed:
Mar 16, 2018
Appl. No.:
15/923612
Inventors:
- Woburn MA, US
Lawrence D. Knox - Hopkinton MA, US
Travis Lee Hein - Holliston MA, US
Steven N. Brown - Hopkinton MA, US
Brian Alexander Selden - Concord MA, US
Assignee:
ClearMotion Acquisition I LLC - Woburn MA
International Classification:
B60N 2/39
B60N 2/38
B60N 2/02
Abstract:
A seat system for a vehicle includes a seat having a seat bottom on which a person can sit. An intermediate support structure is secured to the seat and the vehicle which allows the seat to rotate relative to the vehicle. An actuator can interact with the seat to cause the seat to rotate relative to the vehicle. One or more sensors can each measure an aspect of motion. A processor can (i) receive input from each of the one or more sensors, (ii) determine from this input a measure of rotation of the vehicle away from a nominal, level horizontal orientation, and (iii) utilize the input to determine a desired rotation of the seat. An angle that the seat has been rotated away from a nominal, level orientation is more than insubstantially larger than an angle that the vehicle has rotated away from a nominal, level horizontal orientation.
