Filed:

Aug 28, 1996

Appl. No.:

08/712638

Inventors:

Mark L. Elliott - Eden Prairie MN
Paul A. Galloway - Prior Lake MN

Assignee:

Seagate Technology LLC - Scotts Valley CA

International Classification:

G11B 5596

US Classification:

360 7708, 360 75

Abstract:

A servo system positions a transducer over a disc surface in a disc drive system. Disc surfaces in the drive each have a plurality of spaced servo samples recorded thereon. The servo samples on at least two of the disc surfaces are recorded in skewed relation to one another. A plurality of transducers are provided and one transducer is associated with each one of the plurality of disc surfaces. An actuator arm assembly is coupled to the transducers to move the transducers relative to the disc surfaces. A servo control system is coupled to the actuator arm assembly to control position of the actuator arm assembly. The servo control system includes a reader configured to read servo samples from at least two disc surfaces such that at least two servo samples are read within one servo time period.

Appl. No.:

10/219651

Inventors:

Gregory James Gliniecki - Cary IL, US
Mark Thomas Elliott - Elgin IL, US

Assignee:

ComputerProx Corporation - Elgin IL

International Classification:

G06F 1/26

US Classification:

726 34, 340287, 340288, 340289, 340290, 340291, 726 19

Abstract:

A device in one example comprises a standalone universal serial bus keyboard emulator and an ultrasonic sensor component. The standalone universal serial bus keyboard emulator is coupled with a computer through a universal serial bus port. The ultrasonic sensor component is coupled with the standalone universal serial bus keyboard emulator. The ultrasonic sensor component communicates one or more signals to the standalone universal serial bus keyboard emulator that serve to allow the standalone universal serial bus keyboard emulator to make a determination of entry to or exit from a predetermined proximity of the computer by a user. The determination of entry to or exit from the predetermined proximity of the computer by the user causes the standalone universal serial bus keyboard emulator to send a corresponding entrance or exit user configurable keystroke sequence to the computer through the universal serial bus port.

Inventors:

Mark L. Elliott - Eden Prairie MN, US

Assignee:

Seagate Technology LLC - Scotts Valley CA

International Classification:

G11B 27/36

US Classification:

360 31, 360 75, 324212

Abstract:

A device comprising at least one sensor configured to sense disturbances applied to the data storage device and to generate signals based on the sensed disturbances, and a controller configured to receive the signals from the at least one sensor and to detect jerk events in the sensed disturbances based at least in part on vector differentials of the received signals.

Appl. No.:

6/248644

Inventors:

Mark L. Elliott - Richfield MN

Assignee:

Magnetic Peripherals Inc. - Minneapolis MN

International Classification:

H02P 506

US Classification:

318312

Abstract:

A digital control system is provided to regulate the speed of a brushless DC motor via pulse-width modulation. Digital counters are used to measure the difference between the time for a motor revolution and a reference time. This time difference is in turn used to control the time until the application of power during a fixed period. A motor speed decrease increases the difference in time between a motor revolution and the reference time. This decreases the power pulse delay time and results in an increased power-on time to bring the motor back up to nominal speed.

Appl. No.:

6/869269

Inventors:

Mark L. Elliott - Eden Prairie MN

Assignee:

Magnetic Peripherals Inc. - Bloomington MN

International Classification:

G11B 555

US Classification:

360 78

Abstract:

A high velocity seek deceleration technique is disclosed for seek operations of disk drives wherein measured time per track is compared to a predetermined time per track in a memory as indexed by number of tracks to end of seek determines an error value which adjusts a deceleration amplifier. The gain of digital output to the amplifier is adjusted depending on the number of tracks to end of seek, the higher the number, the higher the gain. Further, a variable bandwidth filter is employed to increase bandwidth as velocity decreases.

Appl. No.:

15/714151

Inventors:

- Cupertino CA, US
Mark Lowell Elliott - Eden Prairie MN, US
Raye A. Sosseh - Minneapolis MN, US

International Classification:

H02P 3/18
G06F 1/26
H02J 9/06

Abstract:

A back electromotive force of a rotating motor is converted into a voltage for a load by driving, in accordance with a duty cycle, at least one switching circuit that couples the back electromotive force to a load through a rectifying circuit. An error signal is generated that is a difference between the load voltage and a reference voltage. The duty cycle is controlled as a function of the error signal to cause the load voltage to approach the reference voltage.
