20080208863 | Compound Item Locking Technologies - The present invention provides technologies including an item management system for the management of compound items and the storage of such items in tabular format using storage systems such as a database management system. Compound items may include file items which may be stored in a file format using storage systems such as a file system. The present invention further provides technologies for locking such compound items upon access by an application to preserve integrity of the items. In particular, the technologies allow for locking compound items including file items where the file items may be accessed via the item management system and/or via an associated file system. | 08-28-2008 |
20100198800 | ALLOCATION LOCKS AND THEIR USE - Systems and methodologies are provided that employ an allocation lock, which permits only a single transaction to acquire space on a particular page at any one time. The allocation lock of the present invention facilitates operations of concurrent transactions at a subpage level (e.g., a row level), and in conjunction with a heap manager can enforce a set of conditions such that prior to a commit stage of a transaction, a space availability for a particular page can be typically assured (e.g., that transactions operating on various copies of the page do not consume all of storage space on that page), and reorganization of data around the page is mitigated (e.g., that a transaction need not move data around the page for purpose of merging various copies.) | 08-05-2010 |

20080288487 | Typed Relationships between Items - Aspects of the subject matter described herein relate to creating, maintaining, and using relationships between items. In aspects, items such as files, folders, and other objects may be stored in a data store. A user may desire to form a relationship between two items that provides additional semantic information regarding the relationship. To do so, an instance of an item reference is created and populated with data that associates the item reference with a source item and optionally a target item. The item reference is part of a type hierarchy and inherits properties from ancestor types. These types are included in a payload of the item reference and may be exposed to programs that seek to obtain information about the relationship indicated by the item reference. An item reference may be added without changing other data about the referenced items. | 11-20-2008 |

All the components are prealigned during the crystal manufacturing process to form the optical laser cavity. The width of the cavity should be selected such that nearly all of the laser diode pump output is absorbed by the cavity. | 03-05-2009 |

20130299977 | RAMP-STACK CHIP PACKAGE WITH VARIABLE CHIP SPACING - A chip package includes a stack of semiconductor dies or chips that are offset from each other, thereby defining a terrace with exposed pads. Moreover, surfaces of each of the semiconductor dies in the stepped terrace include two rows of first pads approximately parallel to edges of the semiconductor dies. Furthermore, the chip package includes a high-bandwidth ramp component, which is positioned approximately parallel to the terrace, and which has a surface that includes second pads arranged in at least two rows of second pads for each of the semiconductor dies. The second pads are electrically and mechanically coupled to the exposed first pads by connectors. Consequently, the electrical contacts in the chip package may have a conductive, a capacitive or, in general, a complex impedance. Furthermore, the chips and/or the ramp component may be positioned relative to each other using a ball-and-pit alignment technique. | 11-14-2013 |

20160054090 | CROSSBOW KICKSTAND - A crossbow kickstand accessory which may be affixed beneath a crossbow stock. The kickstand has three positions: (1) a stored position; (2) a kickstand position; and (3) a bipod position. The kickstand position is at approximately a 40 degree angle, and the bipod position is at approximately a 90 degree angle away from the stock of the crossbow. The kickstand position allows the user to set the crossbow down while the stock is in the air making it simple to set down or pick up with only one hand. While the kickstand is open in the kickstand position, it prevents any twisting or rotation of the stand or the crossbow, which will prevent the crossbow from falling over. An alternative embodiment design would move the stand forward along the stock into the stock handle position. | 02-25-2016 |

20110265160 | PASSWORD MANAGEMENT SYSTEMS AND METHODS - Password management systems include a plurality of child nodes and a mother node. Each child node includes a secure resource, a target account, and a password management service. The target account can be password-protected, and the secure resource can be accessible through the target account. The password management service can periodically update a password of the target account by requesting a new password from the mother node. In response to such requests, the mother node can generate new passwords and forward the new passwords to the appropriate child nodes. The mother node can store the new passwords in a database of current passwords. When an authorized user of the mother node requests a current password for a target account of a child node, the mother node can provide the requested current password to the authorized user. Other aspects, features, and embodiments are also claimed and described. | 10-27-2011 |
