Abstract: A mail server collects messages from a number of user accounts and presents them to the user from a single location. The user can set the mail server to block unwanted messages and to forward others to various receiving devices, including mobile telephones and pagers. Forwarded messages are automatically reformatted for the receiving device, while a copy of the original message is retained. The retained copy can be viewed later if the user is interested in message content that was not available to the wireless device. The user can also use the wireless device to forward the original message to another receiving device. In the case of forwarding, the saved original message and not the reformatted message is sent to the forwarding address. Some embodiments include an email agent that automatically pushes messages from intranet clients to the mail server through a firewall, thereby enabling the mail server to consolidate messages from intranet and Internet sources.

Abstract: A processor includes a translation look-aside buffer (TLB) that relates virtual page addresses to both physical page addresses and main-memory addresses. If the processor references a virtual page address in the TLB for which there is no corresponding information in cache, the processor passes the main-memory address directly to main memory, avoiding the latency normally associated with systems that translate a physical page address to a main-memory address before accessing information from main memory.

Abstract: A Network Interface device (NI device) coupled to a host computer receives a multi-packet message from a network (for example, the Internet) and DMAs the data portions of the various packets directly into a destination in application memory on the host computer. The address of the destination is determined by supplying a first part of the first packet to an application program such that the application program returns the address of the destination. The address is supplied by the host computer to the NI device so that the NI device can DMA the data portions of the various packets directly into the destination. In some embodiments the NI device is an expansion card added to the host computer, whereas in other embodiments the NI device is a part of the host computer.

Abstract: Described are memory systems designed to emphasize differences between memory-cell access times. As a consequence of these access-time variations, data read from different memory cells arrives at some modified output circuitry. The output circuitry sequentially offloads the data in the order of arrival. Data access times are reduced because the output circuitry can begin shifting the first data to arrive before the slower data is ready for capture. Differences between data access times for cells in a given memory array may be emphasized using differently sized sense amplifiers, routing, or both.

Abstract: An inductive transducer has inorganic nonferromagnetic material disposed in an apex region adjacent to a submicron nonferromagnetic gap in a magnetic core. The inorganic nonferromagnetic material has a much lower coefficient of thermal expansion than that of hardbaked photoresist, reducing pole tip protrusion even if other insulation surrounding the coil sections within the core is made of hardbaked photoresist. Alternatively, the entire insulation surrounding the coil sections within the core, in addition to the apex region, can be formed of inorganic nonferromagnetic material, further reducing pole tip protrusion. The transducer has SiO2 rather than alumina in an undercoat layer joining the wafer substrate and the thin film layers of the transducer. SiO2 may also replace alumina in other areas, such as a piggyback layer joining the inductive transducer with a magnetoresistive transducer.

Abstract: Variable optical attenuators that use a blade in a gap between two fibers to control the optical attenuation without having coupling optics in the gap, where the blade has at least one blade surface at an angle with respect to an end facet of one fiber.

Abstract: A method of making an inductive transducer having inorganic nonferromagnetic material disposed in an apex region adjacent to a submicron nonferromagnetic gap in a magnetic core. The inorganic nonferromagnetic apex region can be made by chemical etching of a layer of inorganic nonferromagnetic material, deposition of inorganic nonferromagnetic material through a mask that is then lifted-off, or anisotropic etching of a layer of inorganic nonferromagnetic material that is covered by a hardbaked photoriesist mask.

Abstract: In one aspect, an inductive transducer is disclosed having a leading pole layer and a leading pole tip, with the pole layer being further removed than the pole tip from a media-facing surface. In another aspect, an inductive transducer is disclosed having a magnetic pedestal disposed between a leading pole layer and a leading pole tip, with at least one of the pedestal and pole layer being further removed than the pole tip from a media-facing surface. In another aspect, a leading pole layer or pedestal may have a surface that slopes away from the media-facing surface with increasing distance forward from the leading pole tip.

Abstract: An inductive transducer having first and second magnetic pedestals disposed between first and second magnetic pole layers and adjacent to a media-facing surface, the pedestals separated by a submicron, nonmagnetic gap. The first pedestal extends less than the second pedestal from the media-facing surface, defining a short throat height. The second pedestal extends further to provide sufficient area for stitching to the second pole layer. The stitching and the thickness provided by the pedestals allow plural coil layers to be disposed between the pole layers, and the second pedestal, as well as other features, can be defined by high-resolution photolithography. The two coil layers have lower resistance, lower inductance and allow the pole layers to be shorter, improving performance. All or part of either or both of the pedestals may be formed of high magnetic saturation material, further enhancing performance.
