A work management system (1) includes: an image capturing device (20) worn by a worker; and a server device (60). The image capturing device (20) includes: an image capturing section (21) for capturing an image of a work range of the worker; and a communication section (30) for transmitting, to the server device (60), at least one of (i) the image captured by the image capturing section (21) and (ii) generated information generated in accordance with the image. The server device (60) includes a control section (70) for managing the at least one of the image and the generated information which one is received from the communication section.

Systems and methods for controlling chlorinators for pools and spas are provided. A controller communicates with a processor positioned within a replaceable cell cartridge of a chlorinator, to allow for remote control and diagnosis of the chlorinator and/or cell cartridge. The cell cartridge stores, in non-volatile memory on board the cartridge, one or more parameters associated with the cartridge. The controller can obtain this information from the processor of the cell cartridge, and can use same to configure operation of the chlorinator. Information relating to remaining cell life can be updated by the controller and stored in the non-volatile memory of the cell cartridge. Electrical and software-based mechanisms are provided for ensuring operation of only compatible cell cartridges with the chlorinator. A system for remotely diagnosing errors associated with the chlorinator is also provided.

A method and system for trend dynamic sensor imaging is described herein. In one embodiment a plurality of data sets is received and the plurality of data sets is pre-processed to transform the data of the plurality data sets to have a common scale. The pre-processed plurality of data sets is displayed by plotting the transformed data of the plurality of data sets on a grid according to a color gradient.

A debugging method for production line devices may include: receiving control commands for a plurality of first devices in a production line, where respective control programs may be configured for the plurality of first devices; and calling the control programs for the plurality of first devices according to the control commands for the plurality of first devices respectively so as to debug the plurality of first devices.

A robot system, includes: a robot; a camera configured to capture an image of operation of the robot; and a circuit configured to: control the robot so as to perform work in accordance with work contents information preliminarily stored to indicate a series of work contents; save image information captured by the camera during work performance by the robot in association with time information; and display the saved image information together with the time information.
