Various examples are disclosed for hybrid alert and action solution in Internet-of-Things (IoT) networks. A multi-edge alert definition specifies a plurality of IoT devices that communicate through edge devices. The multi-edge alert definition is decomposed decompose into individual edge alert sub-definitions. Each of the individual edge alert sub-definitions is evaluated using data from individual ones of the edge devices. An alert is triggered based on one of the individual edge alert sub-definitions being met.

The disclosure relates to a method for interacting with a user of a rechargeable-battery-operated machining tool, which can be supplied with energy by means of an exchangeable rechargeable battery pack or exchangeable rechargeable battery. According to the disclosure, in one method step a power characteristic variable of the exchangeable rechargeable battery pack or exchangeable rechargeable battery is sensed by means of a sensing unit of the rechargeable-battery-operated machining tool and/or of the exchangeable rechargeable battery pack or exchangeable rechargeable battery at defined times during the operation of the rechargeable-battery-operated machining tool, and in an additional method step the frequency with which the exchangeable rechargeable battery pack or exchangeable rechargeable battery has been operated at its power limit is calculated. The disclosure also relates to a system, comprising a rechargeable-battery-operated machining tool and an exchangeable rechargeable battery pack or exchangeable rechargeable battery, for carrying out the method.

A textile production monitoring system includes an electronic device connected with a sewing machine, and with sensors connected with the knife, the pedal, the motor tach of the sewing machine, and with the needle, the sensors transmitting signals to the electronic device. A microprocessor evaluates the four signals received from the sensors in a coordinated way. A software possessing a four-signal algorithm generates information about the products, information on which operator works on which machines for how long, how much product they produce, failure status, and machine efficiency. An Rfid module is connected with the electronic device for monitoring the information and working status of the personnel working on the sewing machine. At least one barcode reader allows for entering information on which order the product sewn in the sewing machine belongs to. A wireless connection module facilitates transfer of the information from the electronic device and the microprocessor wirelessly.
