Assignee:

Intel Corporation - Santa Clara CA

International Classification:

F04D 29/66

US Classification:

415119, 416500

Abstract:

Apparatus, systems, and methods may operate to distribute acoustic spectral energy associated with a primary blade-passing frequency tonal component of fan noise and with harmonics thereof. The energy may be spectrally distributed by irregularly spacing a plurality of fan blades or stationary structures associated with the fan, or both. The stationary structures may be capable of being pressure-coupled to each one of the plurality of fan blades as each fan blade passes by each one of the stationary structures. Other embodiments are described and claimed.

Appl. No.:

11/349774

Inventors:

Eric Gordon Baugh - Portland OR, US
Tetsuo Semba - San Jose CA, US
Matthew T. White - Mountain View CA, US

Assignee:

Hitachi Global Storage Technologies Netherlands B.V. - Amsterdam

International Classification:

G11B 21/02

US Classification:

360 75, 360 7704

Abstract:

A magnetic recording disk drive has a disturbance sensor and a disturbance frequency identifier that are used to adjust the frequency of a peak filter as the disturbance frequency changes. The sensor and the frequency identifier are separate from the servo control loop and thus do not rely on the head position error signal (PES) to predict the disturbance frequency. The adjustable peak filter is coupled in parallel with the servo feedback controller. The peak filter modifies the open loop transfer function and the error rejection function of the servo control loop to provide a higher rejection at the identified frequency. The peak filter may be switched out of or uncoupled from the servo feedback controller during track-seeking or as desired, depending on the amplitude of the sensor signal or the amplitude of the PES.

International Classification:

H09F 27/00

US Classification:

381124, 73660, 73662

Abstract:

The present invention is directed towards a family of vibroacoustic emulators to simulate the vibroacoustic characteristics of components of an electronic device. Specific embodiments for simulating a hard disk drive comprise a housing and a vibroacoustic generator coupled to the housing. Various embodiments enable acoustic emulation through a cover side and base side, out-of-plane vibrational emulation to simulate hard disk drive during seek periods, and in-plane vibrational emulation to simulate a hard-disk drive during idle periods. Methods for using the vibroacoustic emulators to characterize system noise are also disclosed.

International Classification:

G11B 5/596
G11B 21/02

US Classification:

360 7702, 360 7706, 360 7804

Abstract:

Embodiments of the present invention provide a way to modify the controller of a HDD head actuator to increase the error rejection capability and suppress the wideband vibration that affects the head motion. In one embodiment, a system to suppress influence of an external disturbance to an actuator comprises a controller providing a controller output as an actuator input to drive an actuator; a feedback loop to feed a head signal at an output of the actuator back as an input to the controller to produce an error signal; and a plurality of peak filters coupled to the controller and having different peak frequencies. Each peak filter has a peak filter input including the error signal, and has a peak filter output. A supervisor module is coupled with the peak filters to selectively add or delete the peak filter output of each peak filter to the actuator input to drive the actuator.

International Classification:

H05K 7/20

US Classification:

361696000, 417423100

Abstract:

A fluid mover includes a rotor to transfer momentum with a fluid when operated at a given volumetric flow rate through the rotor. The rotor includes a plurality of enclosed passages to transfer momentum in or out of the fluid as the fluid passes through the enclosed passages in response to rotation of the rotor. The passages are formed with a cross sectional shape and cross sectional dimensions along their entire length sufficient to establish and maintain laminar flow of the fluid along the entire length of the enclosed passages when the fluid is passing through the rotor at the given volumetric flow rate. The fluid mover also includes a housing having at least one inlet and at least one outlet for the fluid.

Abstract:

Systems and methods for controlling cooling fan speed based on ambient noise levels are disclosed. Some embodiments may include a method for controlling cooling fan speed. The method may include receiving an indication of a current ambient noise level at a computer system and predicting noise due to one or more cooling fans at an expected operator position for the computer system based on a first speed of the cooling fan(s). Embodiments of the method may also include comparing the predicted operation position noise due to the cooling fan(s) with the current ambient noise level and adjusting the cooling fan(s) to a second speed based on the comparison between the predicted operator position noise and the current ambient noise level. Other embodiments are disclosed and claimed.
