Filed:

Mar 31, 2000

Appl. No.:

09/540246

Inventors:

John E. Scura - Thousand Oaks CA 91360
Frank Obregon - San Ramon CA 94583
Lam Tran - San Jose CA 95112

International Classification:

G11B 2120

US Classification:

3602453, 3602451

Abstract:

A head suspension assembly comprising a visco-elastic coupling between a load beam dimple or protrusion and a suspension flexure to which a slider is rigidly coupled. The damping material is selected for a low static modulus, which reduces mechanical vibration by absorbing kinetic energy and releasing the energy as heat. The gimbaling function of the suspension is not significantly effected by the damping material because the damping effect occurs primarily when there is an undesirable relative velocity (movement with respect to time) between the dimple and the flexure.

International Classification:

G11B 5/54
G11B 21/22

US Classification:

3602562, 3602651

Abstract:

The invention includes a yoke assembly containing a top and a bottom proximity latch magnet. The invention includes a voice coil attached to a voice coil bias steel. The crash stop includes a magnetic proximity latch created by the voice coil bias steel attracted to the top and bottom proximity latch magnets. It may also include using the magnetic proximity latch with a magnetically weakened contact latch. Experiments have shown that the combined magnetic proximity latch and the magnetically weakened contact latch require significantly less initial releasing force than the prior art crash stops, and meet rotary shock requirements. The invention includes making the actuator assembly, the voice coil motor assembly, and the CSS hard disk drive. The invention includes operating the CSS hard disk drive with at least the magnetic proximity latch.

G01N 27/26

US Classification:

2057775, 20440314

Abstract:

Enzyme-based electrochemical sensors comprising transition metal complexes of iron, cobalt, ruthenium, osmium, and vanadium are described. The transition metal complexes can be used as redox mediators and include substituted or unsubstituted pyridyl-imidazole ligands. Transition metal complexes attached to polymeric backbones are also described.

Abstract:

Embodiments of the present disclosure relate to analyte determining methods and devices (e.g., electrochemical analyte monitoring systems) that have a sensing surface that includes two or more sensing elements disposed laterally to each other, where the sensing surface is on a working electrode of in vivo and/or in vitro analyte sensors, e.g., continuous and/or automatic in vivo monitoring using analyte sensors and/or test strips. Also provided are systems and methods of using the, for example electrochemical, analyte sensors in analyte monitoring.

C12Q 1/00

Abstract:

Methods and analyte sensors including at least a first working electrode having a first active area thereon, and performing a dip coating operation to deposit a bilayer membrane upon the first working electrode and the first active area. The bilayer may include an inner layer having a first membrane polymer and an outer layer having a second membrane polymer, the first membrane polymer and the second membrane polymer differing from one another. The dip coating operation may comprise one or more first dips in a first membrane formulation to form the inner layer of the bilayer membrane and one or more second dips in a second membrane formulation to form the outer layer of the bilayer membrane upon the inner layer.

International Classification:

H04L 9/40

Abstract:

A system and method for authenticating users of a data processing platform stores a mapping of a unique user platform identifier to multiple user identity provider identifiers associated with multiple realms for a same user. In some examples, the method includes receiving a request from a client device to establish an access session to perform one or more actions on data of the data processing platform and receiving, from at least one of the first external identity provider of the first realm or the second external identity provider of the second realm, a user identity provider identifier associated with the request. In certain examples, the method includes granting permission to perform the one or more actions on the data of the data processing platform based at least in part on the received user identity provider identifier.
