摘要： A program generation system is described that generates a program based on a plurality of input-output examples. The input-output examples include input items and corresponding output items. The program generation system can include three component modules. A parsing module processes the input items and output items to provide a plurality of input parts and output parts, respectively. A transformation module determines, for each output part, whether the output part can be produced from a corresponding input part using one or more converter modules selected from a collection of candidate converter modules. A formatting module generates formatting instructions that transform selected output parts into a form specified by the output items. These three modules provide a generated program that embodies logic learned from the input-output examples; the generated program can be subsequently used to transform new input items into new respective output items.

摘要： A clip for retaining thin plastics film material (6) in tension formed of a pair of elongate channel members (2,4) removably assembled together in inverted relationship. The film material passes through the fixing between opposed cooperating complementary sinuous surfaces (8,3;9,12) of the flanks of the channel members and in so doing passes over surface portions of the fixing at the entrance to the cooperating surfaces of each flank pair, which are exposed to direct radiation. To avoid degradation of the plastics at these surface portions, means (30,32) are provided on one of the channel members to cover or shield these surface portions from such direct radiation. The covering or shielding (30,32) may be integrally formed with one of the channel members of removably afixed thereto.

摘要： A portable electronic device has a keypad for entering alphanumeric characters including a plurality of single contact keys and a multi-way shift key. A character is entered by actuating a single contact key (2) alone or in combination with the multi-way shift key (3). The multi-way shift key (3) may be a four-way rocker switch, with each single contact key having five character labels, four of which are arranged to indicate the direction in which the rocker switch should be actuated to enter the corresponding character.

摘要： A compression method and apparatus are provided for use in image data processing where two-dimensional pixel images have respective absolute depth values specified per pixel, and that depth data is required to be compressed prior to transmission or storage with the image data. The process of compressing the depth data per image begins by determining patches of adjoining pixels of the image (90), which pixels of a patch have the same or similar depth values, and assigning a common depth value to all pixels of the patch. Next, pixel patches having the same or similar common pixel depth values are grouped together (92), and a common depth value is assigned to all pixels of the patches so grouped, following which for each discrete pixel depth value, a determination is made (94) as to the area or number of pixels of the image having that depth value. For the smallest of these areas, the depth value of each of those pixels concerned is modified (100) to the nearest existing discrete depth value. The determination of smallest area and consequent reassignment of depth value is then repeated until only a predetermined number N (for example 16 or 32) of discrete depth values remain. The reassignment of depth values with reference to the depths of adjoining pixels means that the depth data reduced to the N discrete levels may then be run-length coded to achieve a substantial reduction in depth data volume.
摘要翻译：提供一种用于图像数据处理的压缩方法和装置，其中二维像素图像具有每像素指定的各自的绝对深度值，并且该深度数据在与图像数据传输或存储之前需要被压缩。压缩每个图像的深度数据的过程首先通过确定图像（90）的相邻像素的补片，补丁的哪些像素具有相同或相似的深度值，以及为该补丁的所有像素分配公共深度值。接下来，具有相同或相似公共像素深度值的像素贴片被分组在一起（92），并且将共同的深度值分配给所分组的贴片的所有像素，随后对于每个离散像素深度值进行确定（ 94）关于具有该深度值的图像的像素的面积或数目。对于这些区域中的最小值，将相关的每个像素的深度值修改（100）到最近的离散深度值。然后重复确定最小面积并随后重新分配深度值，直到仅剩下离散深度值的预定数量N（例如16或32）为止。相对于相邻像素的深度重新分配深度值意味着可以对减小到N个离散水平的深度数据进行游程长度编码，以实现深度数据量的显着减少。
