The present invention relates to metering data remote collection technology. It is an object of the present invention to provide a remote collection unit configured such that battery consumption is reduced so as to endure until the term of use elapses. The remote collection unit periodically collects metering data at a first time interval and stores the collected metering data in a memory, and transmits metering data periodically collected and stored at a second time interval, at least from after the previous point in time of transmission to the current point in time of transmission, to a central center server over a wireless communication network, wherein transmission at the current point in time of transmission is performed after whether to perform the transmission is decided depending on communication sensitivity of the wireless communication network.

At a workstation for an order-picking system, with a remote control device are a source load carrier, and a target loading aid of a picking order, wherein the operator reloads at least one article unit according to an order. By actuating a confirmation control element, the operator indicates the completed reloading to a process controller of the workstation, which is configured to trigger a step following the current order. The confirmation control element has a base station and a mobile unit, between which a coupled wireless data communication connection is established. The mobile unit has an actuating element with an electric contactor, an electric energy storage, and a micro controller with a communication interface. Moreover, the data communication connection is only established during an actuation of the actuating element and the transmission of the data telegram.

In a method for operating a household appliance, a communications connection is established between an external operating facility and the household appliance. An application is executed on the external operating facility and configured so as to receive data from and/or to transmit data to the household appliance via the communications connection. An interaction of a user with the application of the external operating facility is detected and the communications connection between the external operating facility and the household appliance is terminated in dependence upon an expiration of a predetermined time interval since a last detected interaction of the user with the application of the external operating facility.

A system and method for remote calibration of an air-quality sensor device. The method includes receiving sensor data from at least one sensor device; analyzing the received sensor data to identify at least statistically-significant values indicating on at least drift from initial calibrated values of each of the at least one sensor device; for each identified drifted sensor device, computing re-calibration updates, wherein the re-calibration updates adjust the initial calibrated values such that readings of the respective drifted sensor device fall within a range of expected values; and transmitting the re-calibration updates to the respective drifted sensor device, wherein the respective drifted sensor device upon receiving the re-calibration updates is configured to update its calibration parameters.

A remote controller, a remote-control system and a control method thereof are provided. The remote controller includes a motion sensing circuit and a wireless communication circuit electrically connected to the motion sensing circuit. The motion sensing circuit determines whether or not a motion of the remote controller complies with one of multiple reference motions. When the motion of the remote controller complies with one of the reference motions, the wireless communication circuit is switched from a sleep state to a working state. The wireless communication circuit that is in the working state determines whether or not a received signal strength indication between the remote controller and a controlled device is greater than or equal to a strength threshold. When the received signal strength indication is less than the strength threshold, the wireless communication circuit is switched from the working state to the sleep state.
