20080304180 | Bias techniques for magnetic tape media - The disclosure is directed to a method for creating a remanence magnetization on a magnetic tape medium. The magnetic tape is first substantially demagnetized, e.g., erased, by an erasure unit having multiple magnetic elements of alternating polarity. The erased magnetic tape is then passed by a bias magnet that creates a remanence magnetization on the magnetic tape. The remanence magnetized magnetic tape is then passed through a servo write head that writes servo patterns to the remanence magnetized magnetic tape. The bias magnet may be housed within the erasure unit or within a bias unit, and the distance between the bias magnet and the tape path of the magnetic tape may be adjustable to create the desired remanence magnetization on the magnetic tape. The remanence magnetization created on the magnetic tape may be greater than 20 percent to reduce defects in the servo pattern written to the magnetic tape. | 12-11-2008 |

The magnetic particles may be selected from the group consisting of magnetic platelet-shaped particles and magnetic particles with an aspect ratio less than or equal to approximately 1.5. In addition, the milling process may include milling the plurality of magnetic particles so a magnetic medium formed in the absence of an applied magnetic field exhibits a longitudinal squareness less than or equal to approximately 0.40. | 10-06-2011 |
20110244118 | Method of Forming Barium Ferrite Magnetic Storage Media - Magnetic storage media and methods for constructing magnetic storage media that include a multilayer structure are described. In general, the magnetic storage media include a substrate, an underlayer formed over the substrate, and a magnetic layer that includes a plurality of magnetic particles formed over the underlayer. In some examples, a magnetic recording medium can be formed by forming an underlayer over a substrate, drying the underlayer, and heat-curing the underlayer prior to forming a magnetic layer over the underlayer. A magnetic layer can then be formed over the underlayer. The magnetic layer may includes a plurality of magnetic particles selected from the group consisting of magnetic platelet-shaped particles and magnetic particles with an aspect ratio less than or equal to approximately 1.5, may then be formed over the underlayer. By heat-curing the underlayer prior to forming the magnetic layer over the underlayer, the formed magnetic recording medium may exhibit an improved magnetic recording surface for recording and storing data. | 10-06-2011 |

20150338430 | EXCESSIVE VEHICLE ACCELERATION DETECTION USING A MOBILE DEVICE - Techniques are described for measuring acceleration of a vehicle with a mobile device. The techniques are applied to detect excessive acceleration events of the vehicle. The techniques are implemented in a mobile device that includes an accelerometer, a global positioning system (GPS) sensor, and a processor configured to identify an excessive acceleration event of a vehicle that the mobile device is located in. The processor is configured to receive, from the accelerometer, a first acceleration data when the vehicle is a rest and a second acceleration data when the vehicle is moving. The processor is also configured to determine, based on the first acceleration data, a gravity vector, and determine, based on the second acceleration data, an acceleration vector for the mobile device. The processor is further configured to, responsive to determining that a y-coordinate axis of the acceleration vector for the mobile device is aligned with the gravity vector: update the acceleration vector by removing the gravity vector from the acceleration vector for the mobile device, and process the updated acceleration vector to identify the excessive acceleration event for the vehicle. | 11-26-2015 |

20150153935 | RESERVATION SYSTEM - A reservation system associated with an app installed on a user device can be used to regulate access to network-based features of a primary software service offered by the app. Network-based features can include providing access to online content items. Regulating access to these features can prevent overloading the backend service components that provide the network-based features. Growing the user base in a controlled fashion can benefit the user experience. A waitlist with a countdown can be used for users that have installed the app, but who are not yet allowed access to the network-based features of the primary software service. A user interface can display a reservation status (e.g., how many people are in front of the user in line, how many people are behind the user in line, and the like). This can increase user anticipation of the app features and reduce user attrition. | 06-04-2015 |

20080288444 | Evaluating Multi-Table Join Selectivity in a Computer Database - An improved method and apparatus is described for a query optimizer to evaluate multi-table join selectivities in a computer database. The query optimizer includes a statistics manager that finds the most appropriate set of assumptions and statistics to use when calculating the cost of an arbitrary join expression. As described herein, the statistics manager implements a unique bucket representation for the join expression. The bucket representation for the join expression can be evaluated and compared to the traditional domino expression so that the best possible estimate can be used. This new representation of the join expression allows the query optimizer to more accurately estimate the join selectivity for many queries compared to traditional representations. | 11-20-2008 |

20120205902 | SNOWMOBILE CHASSIS WITH TUNNEL - A snowmobile chassis includes dual panels that form a lighter weight and stronger tunnel preferably without the need for structural doublers, plates or other attachable reinforcement devices. The dual panels take the form of inner and outer panels coupled together with selective gaps or spaces located between the panels. The gaps laterally separate the panels and may be continuous and take a variety of shapes as defined by each panel's configuration. The arrangement of the gaps may advantageously define a desired structural load path through the tunnel, increase a section modulus with respect to a centerline of the tunnel, and reduce an overall weight of the tunnel as compared with conventional tunnels that utilize added reinforcement devices. | 08-16-2012 |
