Abstract: An object is to provide a data collection device and the like capable of reducing a load on an IoT terminal in metadata transmission and power consumption associated with the metadata transmission. In the present invention, a controller is provided on a data collection side that collects metadata, the metadata transmitted from an IoT terminal is grasped, and the IoT terminal is instructed to reduce the transmission frequency of metadata that does not need high real-time property according to a sensor, the type of the IoT terminal, or the like. The IoT terminal transmits the metadata only at a window time (transmission timing, data size, metadata type, or the like) permitted by the metadata controller. As a result, the IoT terminal transmits the metadata only at a limited timing, and thus can reduce a transmission load and power consumption.

Abstract: An activity recording device includes: a work specifying unit for specifying a work of a worker; a position specifying unit for specifying a position of the worker from a position coordinate of the worker; a state specifying unit for specifying a state of the work of the worker from the position specified by the position specifying unit; and a recording unit for recording, as activity data, the work, the position, and the state in association with an activity time, wherein the position specifying unit includes a position estimation unit and a position correction unit.

Abstract: This activity recorder for recording, as activity data, an activity of a worker, includes: a first specification unit for specifying the worker; a second specification unit for specifying a position of the worker; a third specification unit for specifying a target of the worker; a fourth specification unit for specifying a mode of the worker; and a recording unit for recording, as the activity data, the worker, the position, the target, and the mode, with a specified time as an activity time associated therewith, the worker, the position, the target, and the mode having been respectively specified by the first specification unit, the second specification unit, the third specification unit, and the fourth specification unit.

Abstract: An image analysis device for analyzing image data acquired in time series, the image analysis device including: a feature quantity calculation unit for calculating feature quantity time-series data indicating time-series change in a feature quantity, from color information about each pixel of each image data, and storing the feature quantity time-series data in a feature quantity time-series DB; and a variation cycle calculation unit for extracting the feature quantity time-series data from the feature quantity time-series DB and calculating a variation cycle of the image data.

Abstract: A work state measurement device comprises an observation timing notifying unit which notifies observation starting timing and observation finishing timing as observation timing to an observer in every preliminarily set time interval, an observation state input unit in which the work state which is observed is divided into a plurality of work state items and an observation state record unit which weights work state items which are inputted in the observation input unit while from observation starting timing to observation finishing timing by information of the work state items which are inputted and records the work state items as observation states.

Abstract: This ground tint image generating routine sets an arrangement area where a plurality of character strings are arranged, sets an arrangement start line of a character string at least within the arrangement area (S100), arranges a plurality of character strings from a start position of the arrangement start line in a predetermined direction in a predetermined order, arranges the character string from a start position of the arrangement start line of a next line (S170 to S210) when a character string to be arranged next is outside of the arrangement area, and generates a ground tint image (background image) in an area including the arrangement start line by using a plurality of character strings arranged within the arrangement area (S220).

Abstract: A copying apparatus for copying an image of an original document on a recording paper, the copying apparatus includes: a reading section that transports paper, which is an original document or recording paper and is placed on a paper placing section capable of containing the paper, and reads a size and an image of the paper; a printing section that performs printing on the paper and discharges the paper; a switching transport section that switches transporting of the paper, of which the image is read by the reading section, to the printing section side and discharging of the paper.
