Abstract: A computer system implements a memory unit, which includes first DRAM devices, second DRAM devices, a first memory controller, and a second memory controller. Each of the first DRAM devices have a first individual memory capacity and each of the second DRAM devices have a second individual memory capacity. The first memory controller is in signal communication with the first DRAM devices and the second memory controller is in signal communication with the second DRAM devices. Each of the first DRAM devices and the second DRAM devices are selectively operable as one of an active DRAM device to stare application data or a spare DRAM device reserved to receive the application data from the active DRAM devices to dynamically over-provision a total memory defined by a sum of the first and second individual memory capacities.

Abstract: A magnetic sensor having adjustable electrical dimensions, such as electrical read width and electrical stripe height, is disclosed. The magnetic sensor includes a sensor stack with one or more bias electrodes positioned with respect to the sensor stack. The electrical width or electrical stripe height of the sensor stack is a function of a voltage applied to the bias electrodes. The electric field produced by the bias electrodes alters the electrical profile of the magnetoresistive device.

Abstract: The present invention relates to treatments for atom probe components. For example, certain aspects are directed toward processes for treating an atom probe component that includes removing material from a surface of the atom probe component (e.g., using an ion beam, a plasma, a chemical etching process, and/or photonic energy). Another aspect of the invention is directed toward a method for treating an atom probe specimen that includes using a computing device to automatically control a voltage used in an ion sputtering process. Still other aspects of the invention are directed toward methods for treating an atom probe component that includes introducing photonic energy proximate to a surface of the atom probe component, annealing at least a portion of a surface of the atom probe component, coating at least a portion of a surface of the atom probe component, and/or cooling at least a portion of the atom probe component.

Abstract: The magnetoresistive sensor has an MR stack and side shields formed by contacts and/or pedestals on either side of the MR stack. The materials for the contacts and pedestals are selected to be magnetically soft, electrically conductive and have a low AMR signal. The contacts and pedestals are magnetically decoupled from the hard bias materials by placement of spacers.

Abstract: A magnetoresistive sensor having an MR stack biased by high anisotropy hard bias elements thereby reducing distortion in sensor operation and improving head to head operational values. The high anisotropy hard bias elements are formed from a hard magnetic material deposited in a thin film having a substantially axial preferred direction of magnetic anisotropy prior to application of a setting field. The magnetic anisotropy in the hard magnetic material is formed by oblique deposition in a direction approximately normal to the preferred direction of anisotropy in the resulting hard bias element.

Abstract: A transducing head includes a first bias element, a second bias element, and a magnetoresistive sensor positioned between the first bias element and the second bias element. The first bias element and the second bias element are each formed of a permanent magnet material having a remanent magnetic moment in a range of about 200 to about 800 emu/cm3. In a preferred embodiment, the permanent magnet material is an alloy comprising iron, platinum, and at least one material selected from copper, silver, magnesium, lead, zinc, bismuth, and antimony.

Abstract: A transducing head has a magnetoresistive sensor and a first and a second dual path conductor/magnet structure for providing current to the magnetoresistive sensor and for stabilizing the magnetoresistive sensor. The first and the second dual path conductor/magnet structures are arranged in an abutted-junction configuration on opposite sides of the magnetoresistive sensor. Each of the first and the second dual path conductor/magnet structures has at least one bias layer and at least one conductor layer. Each bias layer is formed upon a bias seed layer positioned over one of the conductor layers. Each bias seed layer is selected to result in the bias layer formed upon it having a coercivity between about 1 kOe and about 5 kOe and an in-plane remnant squareness greater than about 0.8. Most preferably, each of the first and the second dual path conductor/magnet structures is formed of at least two conductor layers interspersed with at least one bias layer.

The first and second permanent magnet bias elements are arranged on opposite sides of the magnetoresistive sensor and recessed a distance away from the magnetoresistive sensor. The transducing head of the present invention achieves increased read sensitivity by recessing the first and second permanent magnet bias elements away from the magnetoresistive sensor.

Abstract: The forced air helmet heater and defroster system for sport and utility vehicles begins with a small motor driven blower. This blower is mounted or fastened to the vehicle and adapted to draw in cold, fresh air from the exterior of the vehicle and force it through a heat source. The heat source warms or tempers this cold fresh air. Then, depending on system configuration, the air exiting the heat source is either forced to an insulated helmet delivery conduit equipped with a break-away connection on the inlet end and a diffuser on the exit end, or it can first be routed to an optional temperature control junction and then to the insulated helmet delivery conduit. The vehicle rider may then place the delivery conduit's exit diffuser between the interior side of the helmet and their cheek or chin whereby the expelling warm air flushes the helmet's interior thus warming the rider's face and breathing air as well as keeping the rider's face shield and eyeglasses defrosted and fog free.

Abstract: An atom probe provides rapidly pulsed field evaporation/desorption of ions from a tip utilizing a local extraction electrode positioned closely adjacent to the tip. A bias potential is applied between the tip and the local extraction electrode which provides an electric field at the tip which is less than but near the field intensity required for field evaporation of ions. Additional potential is applied between the tip and the extraction electrode in relatively low over-voltage pulses to obtain field evaporation of ions without substantially accelerating the ions. The ions extracted from the tip by the sharply defined pulses pass through an aperture in the extraction electrode and are accelerated by a large potential difference between the tip and a detector spaced from the tip and the local extraction electrode.

Abstract: Fatigue lifetime enhancement of the holes formed in structural members occurs by introducing a cold working tool or interference fit fasteners fabricated from shape memory alloy materials. The tool may be employed to expand the wall of a hole while the tool material is raised above the critical transitional temperature. Then, upon lowering the tool material below the critical transitional material, it contracts permitting it to be withdrawn. Bushings and interference fit fasteners may be installed in holes formed in structural members when a shape alloy material bushing or fastener is heated above the critical transitional temperature so that an interference fit results and the hole is cold worked. If the alloy material is not cooled below the critical transitional temperature, the interference fit may be permanently maintained, thereby further enhancing the fatigue life of the members.

Abstract: A heating system has a substantially cylindrical hollow muffle formed of a alumina ceramic with a plurality of heat-generating windings therearound. A light-actuated power control is operatively connected to the windings. A computer is operatively connected to a temperature monitor associated with an article being heated in the muffle. The computer is also operatively connected to a light-signal generator and provides commands to the generator in the form of a train of equidistantly spaced electrical pulses in response to temperature measurements provided by the monitor such that an article can be heated to an elevated steady state temperature and controlled at that steady state temperature within precise predetermined limits. The precise temperature control makes the system particularly valuable in the fabrication of crystals with uniform properties or having special growth requirements.
