Abstract: Techniques for block-based indexing are described. In one embodiment, for example, an apparatus may comprise a multicore processor element, an assignment component for execution by the multicore processor element to generate a plurality of block-attribute pairs, each block-attribute pair corresponding to an attribute value and one of a plurality of data blocks, and an indexing component for execution by the multicore processor element to generate an index block for the plurality of data blocks based on the plurality of block-attribute pairs, the indexing component to perform parallel indexing of the plurality of block-attribute pairs using multiple indexing instances. Other embodiments are described and claimed.

Abstract: The present invention provides an optical path processing method and apparatus. The apparatus includes an FA, an LA, an aspheric lens, a filter, and a reflector, where the FA includes a test optical channel, where the test optical channel is configured to receive test light, and enable the test light to be incident through the LA and the aspheric lens to a surface of the filter; the filter is located between the aspheric lens and the reflector, and is configured to perform transmission on the test light; and the reflector is at a distance of less than or equal to a first preset value away from a focus of light transmitted through the aspheric lens, and is configured to reflect, at a preset angle, the test light transmitted through the filter to a specular surface of the reflector.

Abstract: The present invention provides an optical component and an optical device, and the optical component includes a two-dimensional fiber array and a compensation block, where an end face of the two-dimensional fiber array is obliquely polished as a whole; the compensation block is disposed between the two-dimensional fiber array and another optical component; any two light beams that pass through the two-dimensional fiber array and are emitted from the obliquely polished end face of the two-dimensional fiber array are incident to an end face of the compensation block in parallel, and are incident to an end face of the another optical component in parallel after being refracted by another end face of the compensation block.

Abstract: Systems, storage medium, and methods associated with transfer of content are disclosed herein. In embodiments, a storage medium may have first and second instructions configured to facilitate operation across two computing devices. In embodiments, the first instructions may be configured to enable a source computing device to recognize a sourcing gesture of a user as a command to initiate a cross-device operation, and in response to recognition of the sourcing gesture, generate and transmit a sourcing message to initiate the cross-device operation. The second instructions may be configured to enable the target computing device to recognize a targeting gesture of the user that is complementary to the sourcing gesture, and in response to recognition of the targeting gesture, generate and transmit a targeting message to facilitate completion of the initiated cross-device operation. Other embodiments may be described and/or claimed.
