    • A method and system for generating a hologram include a computer (104) connected to a printer (108). A mathematical description (102) of an object, including for example the physical dimensions of the object, is provided to the computer (104). The computer (104) computes a holographic interference pattern based on the mathematical description (102) of the object, and than transmits the computed holographic interference pattern data (106) to the printer (108). The printer (108) prints or otherwise fixes the holographic interference pattern to a print medium (107) to produce a holograph (110). A holographic (three-dimensional) image (114) of the object can then be produced by directing a light beam (118) from a light source (112) onto a surface of the hologram (110), so that the light will interfere with the pattern to generate the holographic image (114).
    • 用于产生全息图的方法和系统包括连接到打印机(108)的计算机(104)。 包括例如对象的物理尺寸的对象的数学描述(102)被提供给计算机(104)。 计算机(104)基于物体的数学描述(102)计算全息干涉图案,并且将计算出的全息干涉图案数据(106)发送到打印机(108)。 打印机(108)将全息干涉图案打印或以其它方式固定到打印介质(107)以产生全息图(110)。 然后可以通过将来自光源(112)的光束(118)引导到全息图(110)的表面上来产生物体的全息(三维)图像(114),使得光将干扰 生成全息图像的图案(114)。

    • Method and apparatus for reducing a number of storage elements in a synthesized synchronous circuit. In one embodiment, the circuit is represented as a directed, partitioned graph. The graph is divided into a plurality of time-ordered time slots that are bounded by storage elements. The strongly-connected components (SCCs) in the graph are first identified. For each middle SCC where there is slack between the middle SCC and a first SCC and slack between the middle SCC and a second SCC, a time-slot-relative direction is selected for moving the middle SCC. The direction is selected as a function of a number of storage elements required for moving the middle SCC toward the first SCC versus moving the middle SCC toward the second SCC. The middle SCC is then moved in the selected time-slot-relative direction.
    • 用于减少合成同步电路中的多个存储元件的方法和设备。 在一个实施例中,电路被表示为有向的分区图。 该图被分成由存储元件限定的多个时间有序的时隙。 首先确定图中强连接的组件(SCC)。 对于中间SCC与第一SCC之间松弛的中间SCC和中间SCC与第二SCC之间的松弛,选择时隙相对方向来移动中间SCC。 根据将中间SCC朝向第一SCC移动所需的存储元件的数量的方式被选择,而不是将中间SCC朝向第二SCC移动。 然后中间的SCC在选定的时隙相对方向移动。

    • A container (10) adapted for holding, storing, and dispensing various elongated tool bits (28) or other such tool items includes a base (12) with a hinged cover (18) that is substantially completely enclosed within the base (12) when the hinge cover (18) is pivoted to its fully open position by way of a hinge assembly (36, 38) that is also substantially completely unclosed within the base (12). Provisions are made for substantially preventing or at least minimizing any tendency of the tool items (28) to fall or slide loose from their respective tool item receptacles (24) when the container (10) is tipped or inverted. In addition, the tool item receptacles (24) include a number of flats (60) therein for grippingly and releasingly receiving the tool items (28). Such tool item receptacles (24) are also configured to have a large draft angle (64) on their exterior surfaces within a hollow interior space in the base (12) in order to facilitate the ease of removal of a base (12) during injection molding or other forming.

    • The inventive computer system uses a layer of software between the operating system and the hardware that localizes the fail-safe protocols into a single module. The system also uses shared memory allocation functions as the interface with the operating system. The memory allocation function creates data structures to satisfy the requests of the operating system. The system also has a data structure locking mechanism to prevent more than one processor from writing to the data structure at a time. This layer isolates and hides the complexities of the underlying hardware and memory sharing, and presents a simpler view of the hardware as a single system to the operating system that resides above it. Since all of the fail-safe code is in one single module, rather than distributed throughout the operating system, it is easier to test and verify its correct operation, as well as maintain the operating system.
    • 本发明的计算机系统在操作系统和硬件之间使用软件层,将故障安全协议定位到单个模块中。 该系统还使用共享内存分配功能作为与操作系统的接口。 内存分配功能创建数据结构以满足操作系统的要求。 该系统还具有数据结构锁定机制,以防止多个处理器一次写入数据结构。 该层隔离并隐藏底层硬件和内存共享的复杂性,并将硬件视为单个系统到位于其上的操作系统的简单视图。 由于所有故障安全代码都在一个单一模块中,而不是分布在整个操作系统中,因此更容易测试和验证其正确的操作以及维护操作系统。
