    • An optical-to-tactile translator provides an aid for the visually impaired by translating a near-field scene to a tactile signal corresponding to said near-field scene. An optical sensor using a plurality of active pixel sensors (APS) converts the optical image within the near-field scene to a digital signal. The digital signal is then processed by a microprocessor and a simple shape signal is generated based on the digital signal. The shape signal is then communicated to a tactile transmitter where the shape signal is converted into a tactile signal using a series of contacts. The shape signal may be an outline of the significant shapes determined in the near-field scene, or the shape signal may comprise a simple symbolic representation of common items encountered repeatedly. The user is thus made aware of the unseen near-field scene, including potential obstacles and dangers, through a series of tactile contacts. In a preferred embodiment, a range determining device such as those commonly found on auto-focusing cameras is included to limit the distance that the optical sensor interprets the near-field scene.
    • 光学至触觉翻译器通过将近场景场转换为对应于所述近场景的触觉信号为视障者提供帮助。 使用多个有源像素传感器(APS)的光学传感器将近场场景内的光学图像转换为数字信号。 然后由微处理器处理数字信号,并且基于数字信号产生简单的形状信号。 然后将形状信号传送到触觉发射器,其中使用一系列触点将形状信号转换成触觉信号。 形状信号可以是在近场景中确定的有效形状的轮廓,或者形状信号可以包括重复遇到的共同物品的简单符号表示。 因此,用户通过一系列触觉接触了解到看不见的近场景,包括潜在的障碍和危险。 在优选实施例中,包括诸如在自动聚焦照相机上通常发现的范围确定装置,以限制光学传感器解释近场景的距离。

    • A process for realizing mappings between codewords of two distinct (N,K) Reed-Solomon codes over GF(2.sup.J) having selected two independent parameters: J, specifying the number of bits per symbol; and E, the symbol error correction capability of the code, wherein said independent parameters J and E yield the following: N=2.sup.J -1, total number of symbols per codeword; 2E, the number of symbols assigned a role of check symbols; and K=N-2E, the number of code symbols representing information, all within a codeword of an (N,K) RS code over GF(2.sup.J), and having selected said parameters for encoding, the implementation of a decoder are governed by: 2.sup.J field elements defined by a degree J primitive polynomial over GF(2) denoted by F(x); a code generator polynomial of degree 2E containing 2E consecutive roots of a primitive element defined by F(x); and, in a Berlekamp RS code, the basis in which the RS information and check symbols are represented.The process includes separate transformation steps for symbol-by-symbol conversion for a first RS code to ultimately a second conventional RS code capable of being corrected by a conventional RS decoder, followed by a reverse sequence of the inverse of the first set of steps to arrive at codewords having corrected information symbols, at which time check symbols of the RS code may be discarded.

    • A device for measuring strain in substrates at high temperatures in which the thermally induced apparent strain is nulled. Two gages are used, one active gage and one compensating gage. Both gages are placed on the substrate to be gaged; the active gage is attached such that it responds to mechanical and thermally induced apparent strain while the compensating gage is attached such that it does not respond to mechanical strain and measures only thermally induced apparent strain. A thermal blanket is placed over the two gages to maintain the gages at the same temperature. The two gages are wired as adjacent arms of a Wheatstone bridge which nulls the thermally induced apparent strain giving a true reading of the mechanical strain in the substrate.
    • 用于在高温下测量基底中的应变的装置,其中热诱导的表观应变为零。 使用两个量具,一个活动量具和一个补偿量规。 将两个计量管放置在基材上以进行计量; 活性量具附着,使得其响应于机械和热诱导的表观应变,同时补偿量具被附接,使得其不响应于机械应变并且仅测量热诱导的表观应变。 将热毯放置在两个量规上,以将量具保持在相同的温度。 两个量规被连线作为惠斯通电桥的相邻臂,这使得热诱导的表观应变无效,从而给出了衬底中机械应变的真实读数。
