    • A rollable beam measurement apparatus is disclosed. In one embodiment, the apparatus includes a housing including a reel. A rule having a leading edge and a trailing edge is provided and the trailing edge is attached to the reel. An end hook is attached to the leading edge. In preferred embodiments, the rule comprises a pair of opposing rules forming a tubular structure. This new tape rule eliminates the typically unstable and flexible behavior of typical tape rules, providing the ability for stiffness and standout length in all orientations and in all environmental conditions. Furthermore, this invention improves the readability of the tape rule markings as well as maintains the accepted standard for tape rule stowage while providing these benefits.
    • 公开了一种可卷绕的光束测量装置。 在一个实施例中,该装置包括包括卷轴的壳体。 提供具有前缘和后缘的规则,并且后缘附接到卷轴。 端钩连接到前缘。 在优选实施例中,规则包括形成管状结构的一对相反的规则。 这种新的磁带规则消除了典型磁带规则的典型的不稳定和灵活的行为,提供了在所有方向和所有环境条件下的刚度和突出长度的能力。 此外,本发明改进了磁带规则标记的可读性,并且在提供这些优点的同时保持了磁带规则存储的公认标准。

    • A method and system for reducing the number of mathematical operations required in the JPEG decoding process without substantially impacting the quality of the image displayed is disclosed. Embodiments provide an efficient JPEG decoding process for the purposes of displaying an image on a display smaller than the source image, for example, the screen of a handheld device. According to one aspect of the invention, this is accomplished by reducing the amount of processing required for dequantization and inverse DCT (IDCT) by effectively reducing the size of the image in the quantized, DCT domain prior to dequantization and IDCT. This can be done, for example, by discarding unnecessary DCT index rows and columns prior to dequantization and IDCT. In one embodiment, columns from the right, and rows from the bottom are discarded such that only the top left portion of the block of quantized, and DCT coefficients are processed.
    • 公开了一种用于减少JPEG解码过程中所需的数学运算数量而不显着影响显示图像的质量的方法和系统。 实施例提供了一种高效的JPEG解码过程,用于在比源图像(例如手持设备的屏幕)更小的显示器上显示图像。 根据本发明的一个方面,这是通过在去量化和IDCT之前有效地减小量化的DCT域中的图像的大小来减少去量化和逆DCT(IDCT)所需的处理量来实现的。 这可以通过例如在去量化和IDCT之前丢弃不必要的DCT索引行和列来完成。 在一个实施例中,来自右侧的列和来自底部的列被丢弃,使得仅处理量化块的左上部分和DCT系数被处理。

    • A force measuring apparatus uses a flexible cantilever beam engaging a tool at one end and a handle at the other end so that a force, normal to the beam, can be applied and delivered to the tool. Mounted in spaced apart longitudinal alignment on each side of the beam, is a tensioned wire, and a vibratory modulator in electromagnetic communication with the wire causing the wire to vibrate. A vibratory sensor is also positioned on each side of the beam in sensory communication with each respective wire. An electrical circuit is functionally enabled for receiving electrical signals from the vibratory sensor, the signals corresponding to a vibratory frequency of each of the wires, and for controlling the vibratory modulators to maintain the wires at resonant vibratory frequency, and for measuring a differential vibratory frequency between the wires, and finally, for calculating the magnitude of a force applied to the beam in such direction that one of the wires is incrementally further tensioned and the other of the wires is incrementally relaxed. The force magnitude is displayed on the apparatus.
