US Classification:

705014000

Abstract:

Powered platforms for various kinds are each characterized by a corresponding measure of fuel economy. Fuel economy credits are provided to a party who contributes a material that effects an improvement in such fuel consumption for a given powered platform. In a preferred embodiment, such fuel economy credits can be traded. When acquired from another party, such credits can be used to offset fuel economy performance shortfalls. The “material” can comprise any of a wide variety of substances, components, assemblies, design specifications, control strategies (including enabling software), and so forth. The powered platforms can include stationary powered platforms or mobile powered platforms.

International Classification:

G11B 5127

US Classification:

360113

Abstract:

In a magnetoresistive transducer, a conductor configuration in which magnetic fields in the conductors are oriented in the same direction to provide symmetric track profiles and improved track edge response. Conductor area at the transducer air bearing surface is also minimized to eliminate shorting and improve device yield and reliability. In one embodiment of the invention, inductive pickup is minimized by limiting the active width of magnetoresistive sensing elements through conductor placement. Another embodiment of the invention, useful for applications involving dual stripe magnetoresistive transducers, minimizes inductive pickup by providing relatively large conductors for each magnetoresistive stripe, arranged in parallel with each other and coupled differentially to cancel inductive pickup through common mode rejection.

International Classification:

US Classification:

360113

Abstract:

A read/write head for a hard disk provides both a magneto-resistive read function and an inductive write function in a common gap. The inductive write function is provided by a current carrying coil which is magnetically coupled to top and bottom shields or pole tips which in turn induce the magnetic fields required for writing on the disk. Mutually biasing magneto-resistive read sensor are located between the shields, which serve to improve the resolution of the read function. During a read operation, read/write circuitry maintains a current in the coil which cancels, at least partially, magnetic fields induced by sensing and bias currents in the magneto-resistive heads which might other perturb information stored in the medium. This arrangement provides a read/write head with improved read/write resolution as required by emerging high density storage media in compact formats.

C12N 9/24

Abstract:

The present invention relates to host cells having modified lipid-linked oligosaccharides which may be modified further by heterologous expression of a set of glycosyltransferases, sugar transporters and mannosidases to become host-strains for the production of mammalian, e.g., human therapeutic glycoproteins. The process provides an engineered host cell which can be used to express and target any desirable gene(s) involved in glycosylation. Host cells with modified lipid-linked oligosaccharides are created or selected. N-glycans made in the engineered host cells have a GlcNAcManGlcNAccore structure which may then be modified further by heterologous expression of one or more enzymes, e.g., glycosyl-transferases, sugar transporters and mannosidases, to yield human-like glycoproteins. For the production of therapeutic proteins, this method may be adapted to engineer cell lines in which any desired glycosylation structure may be obtained.
