The Hewlett-Packard Company patent solves the following problem:

Imaging devices, such as optical scanner, is well-known in the art and a machine-readable signal image data representative of a scanned object, such as a photograph or a page of printed text . In a typical scanner application, the data signal in the image produced by an optical scanner can be used on a personal computer to reproduce an image of the scanned object on a suitable display device, such as a CRT or a printer.

Our analysis of this patent is as follows:

Hewlett-Packard Company’s patent US 6002124 A deals with Portable image scanner with optical position sensors.
An imaging device could include a picture of the head with an elongate portion thereof with first and second lengthwise ends. The head may also include a first navigation sensor aperture and a second navigation sensor aperture position adjacent to elongate space in positions other than positions Ranged the first and second lengthwise ends of the elongate slot. An image sensing system optically aligned with the elongate head space that is responsive to the light passing through the elongate space and an image signal based on light image. A first navigation sensor optically aligned with the first navigation sensor head aperture image is responsive to first navigation light passing through the first navigation sensor aperture and a first signal tabok- navigation data base on the first navigation light. The second navigation sensor optically aligned with the second navigation sensor head aperture image is responsive to the second navigation light passing through the second navigation sensor aperture and a second signal navigation data base in the second navigation light.

The South Alabama Medical Science Foundation patent solves the following problem:

The folates are ubiquitous to nearly all forms of life. Humans and many other animals lack the capacity to make their own folate which thus is an important vitamin, a kind of important nurient. Anemia especially during pregnancy and geriatric population was an early indication of a dietary requirement for folate. A major function of folate is to remove the unit in a carbon from the molecule metabolized and then deliver them to the molecules synthesized. As an example. folate participate in the building of nucleic acid. Furthermore, the activity of DNA controlled, in part, by methylation, and the primary methylating agent in the body (S-adenosylmethionine) made a metabolic cycle involving a folate. Many studies, therefore, focus on the relationship of folate status to cancer susceptibility, especially colorectal adenoma.

Our analysis of this patent is as follows:

South Alabama Medical Science Foundation’s patent US 5997915 A deals with Compositions for human and animal consumption containing reduced folates and methods for making and using same.
A composition for human or animal consumption for providing folate include a natural isomer of reduced folate, such as (6S) -tetrahydrofolic acid, 5-methyl- (6S) -tetrahydrofolic acid, 5-formyl – (6S) -tetrahydrofolic acid, 10-formyl- (6R) -tetrahydrofolic acid, 5,10-methylene- (6R) -tetrahydrofolic acid, 5,10-methenyl- (6R) -tetrahydrofolic acid, 5-formimino- ( 6S) -tetrahydrofolic acid, and their polyglutamyl derivatives disclosed. The composition included in multivitamin preparations (or without minerals and other nutrients); breakfast foods such as prepared cereals, toaster pastries and breakfast bars; baby formula; Dietary supplements and whole foods and weight-loss formulas and bars; animal feed (for example to pet food) and animal feed supplements (like chicken feed). The amount of natural isomer of a reduced folate in a composition for human consumption include between about 5% and 200% of the daily requirement for folic acid per serving or the dosage.

The Seagate Technology, Inc. patent solves the following problem:

The present invention relates generally to the disc drive system with data storage on a large plaque mounted on a spindle to form a disc stack. Particularly, the present invention relates to a disc drive data storage system of data recorded on various surfaces of the disc groups different recording swarms to optimize the performance of the disc drive.

Our analysis of this patent is as follows:

Seagate Technology, Inc.’s patent US 5999352 A deals with Variable bits per inch recording.
A disc drive and a method of storing data in the disc drive declared. Multiple data each supported adjacent to a corresponding one of many disc on a disc assembly to form the many activities in the head / media. A special guardband or recording density capability in each of the many activities in the head / media determined. A real recording density assigned to each of the many activities the head / media based on the recording density capability for the particular combination of head / media. The actual recording density assigned to each of the many activities in the head / media may differ from the actual recording swarms assigned to other activities in the head / media. The disc drive is controlled so that the data recorded on each of the surfaces in the actual recording density appointed it.
