  • Patent number: 10607121
    Abstract: Before dimension reduction is performed while local data distribution is stored as neighborhood data, a distance between data to be subjected to the dimension reduction is calculated, and a parameter (a neighborhood number of the k-nearest neighbor algorithm or a size of a hypersphere) which determines the neighborhood data is determined for each data to be subjected to the dimension reduction. Thereafter, the dimension reduction is performed on the target data based on the determined parameter.

  • Publication number: 20180373738
    Abstract: An information presentation apparatus obtains monitoring information that indicates a state of a monitoring target, accumulates it in a storage unit, and detects, based on the monitoring information accumulated in the storage unit, the occurrence of an information presentation trigger event. The information presentation apparatus generates, based on the monitoring information accumulated in the storage unit, search data for searching for relevant information related to the detected event, uses the generated the search data to search for the relevant information, and generates presentation information for present the relevant information found by the searching.

  • Patent number: 10156471
    Abstract: A combination scale is provided that includes a combinatorial computation unit and two operation modes; a normal operation mode, and a corrective operation mode in which correction values are decided. The correction values are for use in correcting errors of measured weight values calculated from weight signals of weight sensors. In the normal operation mode, the combinatorial computation unit corrects the measured weight values using the correction values decided in the corrective operation mode. Then, the combinatorial computation unit executes combinatorial computations based on the corrected measured weight values.

  • Patent number: 10151624
    Abstract: A virtual weight value is set, and a dummy run mode is set and activated. Then, a zero point, reference value used to calculate the weight value of articles to be weighed in each weighing hopper, is corrected based on the virtual weight value. This enables a dummy run of a combination scale to be performed with the actually empty weighing hopper being assumed to contain the articles equivalent to the virtual weight value.

  • Patent number: 10071710
    Abstract: The swing member (63) to be subjected to swinging drive is integrally provided to the output shaft (56) outside the speed reducer case (52), the speed reducer case (52) is provided with a pair of swing regulating portions (61, 62) which prevents the swing member (63) from being moved beyond the wiping-allowable limit angle (b°) by contacting the swing member (63). As a result, the swing member (63) and the swing regulating portions (61, 62) can collectively form the regulating member (60). As a result, essential components (such as fixing plate) can be omitted from the conventional wiper apparatus. Therefore, the wiper apparatus can be improved in assembly workability, size and weight by reducing the number of components thereof, and provided with a regulating member (60) which prevents the wiper member being moved beyond the wiping-allowable limit angle (b°).
