摘要： A locking arrangement for data structures is provided that prevents deadlocks, but still allows different threads to simultaneously obtain locks on different nodes of a data structure for both read and write operations. The locking system differentiates locks based on a priority hierarchy. The locking system will fail a request to lock one or more resources in a data structure if access to those resources has already been restricted by a conflicting lock of an equal or higher priority. The locking system may also employ preemptable and non-preemptable locks such that, if a preemptable lock with a lower priority has restricted access to resources, then the locking system will preempt the lower priority lock in favor of a conflicting higher priority lock. Alternately, if a non-preemptable lock with a lower priority has restricted access to resources, then the locking system will wait until the lower priority lock is removed before implementing a requested conflicting higher priority lock. This locking arrangement allows high priority operations that require higher performance and efficiency to receive preferential access to a data structure without preventing lower priority operations from accessing the data structure, while preventing deadlocks between different operations.
摘要翻译：提供了数据结构的锁定装置，其防止死锁，但是仍然允许不同的线程同时获得用于读取和写入操作的数据结构的不同节点上的锁定。锁定系统基于优先级层次来区分锁。如果对这些资源的访问已经受到相同或更高优先级的冲突锁限制，则锁定系统将失败锁定数据结构中的一个或多个资源的请求。锁定系统还可以使用可抢占的和不可抢占的锁，使得如果具有较低优先级的可抢占锁限制了对资源的访问，则锁定系统将优先考虑较低优先权锁以有利于较高优先级的锁定。或者，如果具有较低优先级的不可抢占锁限制了对资源的访问，则锁定系统将等待，直到在执行所请求的冲突较高优先级锁之前移除较低优先权锁。该锁定装置允许高优先级操作，其需要更高的性能和效率来接收对数据结构的优先访问，而不会阻止较低优先级的操作访问数据结构，同时防止不同操作之间的死锁。

摘要： A method of packaging an article comprises wrapping the article in a plastic film; and heat sealing the film using a sealing apparatus comprising a main sealing element, and a second sealing element attached at an angle to the main sealing element, and shorter than the main sealing element, such that when the film is sealed, a sealed notch that can be used to initiate opening of the package is made. A package comprises an article wrapped in a plastic film, the film being heat sealed to form a seal, the seal comprising a main seal, and a second seal attached at an angle to the main seal, and shorter than the main seal, and defining a sealed notch that can be used to initiate opening of the package. A sealing apparatus for making an easily opened package comprises a main sealing element, and a second sealing element attached at an angle to the main sealing element, and shorter than the main sealing element, and capable of creating a sealed notch that can be used to initiate opening of the package.

摘要： Aspects of the invention provide virtual hover zones. When a user lowers a hovering stylus while remaining within a hover zone, cursor control is modified to be more easily controllable by the user. If the user pauses the stylus in mid-air before lowering the stylus, and if the stylus remains within the hover zone, then upon touchdown the cursor may be moved to the projection of the location where the stylus was paused. Any action that my be taken in response to the touch down may be sent to the projection location as well. Also provided are cursor control zones. A dampening zone may be used to provide dampened cursor movement feedback in response to movement input provided by a pointing device. Also, a dead zone may be used to prohibit cursor movement in response to movement input provided by the pointing device.
摘要翻译：本发明的方面提供虚拟悬停区域。当用户在停留在悬停区域的同时降低悬停的触控笔时，光标控制被修改为更容易被用户控制。如果用户在降低触控笔之前在空中暂停触控笔，并且如果触控笔保持在悬停区域内，则在触地时，光标可能会移动到手写笔暂停位置的投影。对于触摸屏而言，我采取的任何动作也可以发送到投影位置。还提供了光标控制区。可以使用阻尼区域来响应于由指示设备提供的移动输入而提供抑制的光标移动反馈。此外，可以使用死区来响应由指示设备提供的移动输入来禁止光标移动。

摘要： The convex hull of two polygons having congruent corresponding angles with the same orientation can be determined by analyzing the relationship of each vertex of one of the polygons relative to its adjacent vertices. More particularly a line may be defined between a selected vertex on one of the polygons and its corresponding vertex on the other polygon. If the vertices adjacent to the selected vertex both fall on the same side of the line, then a line connecting the selected vertex with its corresponding vertex lies on the convex hull of the two polygons. If, on the other hand, the vertices adjacent to the selected vertex are located on different sides of the line, then the line connecting the selected vertex with its corresponding vertex does not lie on the convex hull.
摘要翻译：可以通过分析其中一个多边形相对于其相邻顶点的每个顶点的关系来确定具有相同取向的一致相应角度的两个多边形的凸包。更具体地，可以在多边形中的一个上的所选择的顶点和其他多边形上的对应顶点之间定义线。如果与所选顶点相邻的顶点都落在该线的同一侧，那么连接所选顶点与其对应顶点的线就位于两个多边形的凸包上。另一方面，如果与所选择的顶点相邻的顶点位于线的不同侧面，那么连接所选顶点与其对应顶点的线不在凸包上。
