09/611872

International Classification:

H03M 1300

US Classification:

714780, 714781

Abstract:

A soft error correction algebraic decoder and an associated method use erasure reliability numbers to derive error locations and values. More specifically, symbol reliability numbers from a maximum likelihood (ML) decoder as well as a parity check success/failure from inner modulation code symbols are combined by a Reed-Solomon decoder in an iterative manner, such that the ratio of erasures to errors is maximized. The soft error correction (ECC) algebraic decoder and associated method decode Reed Solomon codes using a binary code and detector side information. The Reed Solomon codes are optimally suited for use on erasure channels. A threshold adjustment algorithm qualifies candidate erasures based on a detector error filter output as well as modulation code constraint success/failure information, in particular parity check or failure as current modulation codes in disk drive applications use parity checks. This algorithm creates fixed erasure inputs to the Reed Solomon decoder. A complementary soft decoding algorithm of the present invention teaches the use of a key equation solver algorithm that calculates error patterns obtained as a solution to a weighted rational interpolation problem with the weights given by the detector side information.

Appl. No.:

11/324575

Inventors:

Spencer W. Ng - San Jose CA, US
Richard Michael Hamilton New - San Jose CA, US
Bruce Wilson - San Jose CA, US

Assignee:

Hitachi Global Storage Technologies Netherlands B.V. - Amsterdam

International Classification:

G11B 15/04

US Classification:

360 60, 360 66, 360 75

Abstract:

WORM safeguards are provided in a magnetic disk drive in which the disks are pre-magnetized or pre-recorded such that all magnetic domains on each recording surface are completely aligned pointing in the same direction. A special write head which can magnetically write only in the direction opposite to the pre-magnetization orientation is also provided.

Appl. No.:

11/200411

Inventors:

Bruce Wilson - San Jose CA, US
Richard Michael Hamilton New - San Jose CA, US

Assignee:

Hitachi Global Storage Technologies Netherlands B.V. - Amsterdam

International Classification:

G11C 29/00

US Classification:

714768, 360 48

Abstract:

Modified HDD sector formats have multiple sets of preamble data. The preambles are well separated so that any defect long enough to wipe out both preambles would also overwhelm the ECC.

International Classification:

D2101

Filed:

Nov 23, 1988

Appl. No.:

7/275814

Inventors:

John Urquhart - Palo Alto CA
Richard G. Hamilton - Fremont CA

Assignee:

Aprex Corporation - Fremont CA

International Classification:

B65D 8304

US Classification:

221 2

Abstract:

A device for monitoring the dispensing of drugs to a patient is disclosed. This device includes a detector which determines the actual physical delivery of the drug dosage to the patient. This eliminates ambiguities associated with devices in the art which only monitor inferentially the dispensing of the drug dosage to the patient. The detector can include an optical sensor which notes the physical passage of the drug dosage through a dispensing port to the patient.

Appl. No.:

7/275294

Inventors:

Richard G. Hamilton - Fremont CA

Assignee:

Aprex Corporation - Fremont CA

International Classification:

G04B 4700
G07F 1100

US Classification:

368 10

Abstract:

A device for detecting the dispensing of drugs from a container in a way which eliminates false detection events due to mishandling of the container is disclosed. The device includes a container which may be opened and closed. It also contains a means for detecting the opening and separately detecting the closing of the container as well as means for measuring the time between these events and comparing this elapsed time to a predetermined standard indicative of drug dispensing event. The times of proper drug dispensing events are stored in the device for use by the health care professional following the patient's drug dosing compliance. Other opening and closing intervals which fall outside this time range give rise to an alternative response. They may be recorded with a notation of their probable error or they may be disregarded. In other aspects, the invention provides a preferred physical configuration for the electronic components of the device and a preferred means for accessing the data stored in the device.

International Classification:

H01L 31/0224
H01L 31/18

US Classification:

136256, 438 98

Abstract:

Enhanced adhesion of seed layers for solar cell conductive contacts and methods of forming solar cell conductive contacts are described. For example, a method of fabricating a solar cell includes forming an adhesion layer above an emitter region of a substrate. A metal seed paste layer is formed on the adhesion layer. The metal seed paste layer and the adhesion layer are annealed to form a conductive layer in contact with the emitter region of the substrate. A conductive contact for the solar cell is formed from the conductive layer.
