Feedforward Controller And Methods For Use Therewith
US Patent:
7499239, Mar 3, 2009
Filed:
Oct 15, 2007
Appl. No.:
11/872474
Inventors:
Michael Chang - San Jose CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
G11B 5/596
US Classification:
360 7809
Abstract:
A controller includes a combining module that generates a total control signal for the drive device of a disk drive by combining a feedback control signal and a feedforward control signal. A feedback control module generates the feedback control signal in response to at least one state of the drive device. A feedforward control module generates the feedforward control signal based on a smoothing function and a feedforward control function.
Controller, State Estimator And Methods For Use Therewith
US Patent:
7436617, Oct 14, 2008
Filed:
Jun 21, 2006
Appl. No.:
11/472229
Inventors:
Michael Chang - San Jose CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
G11B 21/02, G11B 5/596
US Classification:
360 75, 360 7704, 318560
Abstract:
A controller is disclosed that can be used in controlling a drive device of a disk drive, or other systems, in the presence of sinusoidal disturbances. The controller includes a calibration module that generates a plurality of reference states for a reference region of a disk of the disk drive. An initialization state generation module generates a plurality of initialization states for at least one other region of the disk as a function of the plurality of reference states, a displacement between the other regions of the disk and the reference region of the disk, and a reference state transition matrix. A control module generates a control signal for the drive device based on the plurality of initialization states.
Feedforward Controller And Methods For Use Therewith
US Patent:
7295397, Nov 13, 2007
Filed:
May 30, 2006
Appl. No.:
11/443806
Inventors:
Michael Chang - San Jose CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
G11B 5/596
US Classification:
360 7809
Abstract:
A controller includes a combining module that generates a total control signal for the drive device of a disk drive by combining a feedback control signal and a feedforward control signal. A feedback control module generates the feedback control signal in response to at least one state of the drive device. A feedforward control module generates the feedforward control signal based on a smoothing function and a feedforward control function. The smoothing function is determined by evaluating a plurality of candidate smoothing functions by determining a smoothness factor associated with the control signal that results from each of the plurality of candidate smoothing functions, and selecting the smoothing function as one of the plurality of candidate smoothing functions, based on the smoothness factor.
Intelligent Blemish Control Algorithm And Apparatus
US Patent:
7199824, Apr 3, 2007
Filed:
Aug 25, 2005
Appl. No.:
11/212372
Inventors:
Michael Chang - San Jose CA, US
Allan Yeh - San Jose CA, US
Allan Yeh - San Jose CA, US
Assignee:
ESS Technology, Inc. - Fremont CA
International Classification:
H04N 9/64
US Classification:
348246
Abstract:
An image processing method and apparatus is described for processing a signal from a monochrome or color sensor that may be subject to pixel defects or blemishes. Without prior knowledge of any pixel defects, the processing method examines each pixel value and its neighboring pixel values. A number of tests are applied to the set of pixel values to determine whether the underlying pixel is defective. If the underlying pixel is determined to be defective, the pixel value is replaced by an estimate value derived from the values of its neighboring pixels. Otherwise, the pixel value remains intact.
Accurate Tracking Of Coil Resistance Based On Current, Voltage And Angular Velocity
US Patent:
7082009, Jul 25, 2006
Filed:
Feb 19, 2003
Appl. No.:
10/368743
Inventors:
Fernando A. Zayas - Loveland CO, US
Michael Chang - San Jose CA, US
Michael Chang - San Jose CA, US
Assignee:
Matsushita Electric Industrial Co., Ltd. - Osaka
International Classification:
G11B 5/596
US Classification:
360 7804
Abstract:
Methods and computer program products for determining accurate estimates of coil resistance are provided. Current differences between pairs of current values are determined. Additionally, voltage differences between pairs of actuator coil voltages (corresponding to the current values) and angular velocity differences between pairs of angular velocities are determined. Coil resistance is estimated based on the current differences, the voltage differences and the angular velocity differences. These coil resistance estimates can be useful for accurately estimating actuator coil, actuator arm and/or head velocity.
Method And Apparatus For Reducing Clock Speed And Power Consumption
US Patent:
7656907, Feb 2, 2010

Michael A. Sokol - San Jose CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
H04L 7/00, G06F 1/12
US Classification:
370503, 370429, 713400
Abstract:
A system for reducing clock speed and power consumption in a network chip is provided. The system can have a core that transmits and receives signals at a first clock speed. A receive buffer can be in communication with the core and be configured to transmit the signals to the core at the first clock speed. A transmit buffer can be in communication with the core and configured to receive signals from the core at the first clock speed. A sync can be configured to receive signals in the receive buffer at a second clock speed and to transmit the signals from the transmit buffer at the second clock speed. The sync can be in communication with the transmit buffer and the receive buffer.
Adaptive Bit Rate Allocation

Assignee:
ESS Technology, Inc. - Fremont CA
International Classification:
H04N 7/12
US Classification:
37524003
Abstract:
A method for determining quantization numbers for each macro block in one video segment having a prescribed capacity is disclosed. The quantization numbers determine how much data will be preserved for that macro block. The method begins by determining a level of complexity for each macro block. Next, initial quantization numbers are chosen for the macro blocks by choosing the largest values possible without exceeding the prescribed capacity of the video segment. Final quantization numbers are selected based on respective ones of the initial quantization numbers proportioned according to the level of complexity for that macro block. The final quantization numbers may be increased or decreased so that the capacity of the video segment is maximized but not exceeded.
