A system is disclosed for managing a set of electrical/electronic devices for driving fans of a heat exchanger of a refrigeration plant, having a basic control unit adapted to act as interface between a remote control unit/Master unit and a plurality of electrical/electronic devices to be controlled. The basic control unit has a data input to receive inputs from the remote control unit/Master unit and a plurality of data outputs connectable with respective electrical/electronic devices of the electrical/electronic devices. The basic control unit is configured to address the electrical/electronic devices using management signals to program the operating parameters of the electrical/electronic devices, and to directly manage the operation. The management signals include addressing, programming and management commands previously programmed in the memory unit based on specific applications and communication protocols. The basic control unit manages the data outputs independently from the other data outputs, to manage the electrical/electronic devices independently.

A method uses telemetry data based on user habit information or user monitoring. User information is acquired from one or more sensors of a monitoring device. The user information is selected from of at least one of, a user's activities, behaviors and habit information. Signals are routed through ID circuitry at the user monitoring device. User information is communicated between the monitoring device and a telemetry system. A database of user ID's is accessed at the telemetry system. The telemetry system analyzes telemetry data based on at least one of, user's activities, behaviors and habit information, user condition, and user parameter, to create personalized information about the user. One or more contexts of a user activity are associated with an activity manager. The activity manager is a standalone device, included with the telemetry system or included with the monitoring device.

A plurality of terminal devices 3 are connected to a parent device 1 to measure analog voltages of the terminals. Reference voltages 6 and measurement voltages 7 each having a polarity reverse to that of clocks are sequentially switched to be connected at gaps of clocks supplied by the parent device 1. Thus, the reference voltages 6 and the measurement voltages 7 of the terminal devices 3 are directly connected. With this mechanism, measurement of analog measurement signals at multiple points can be performed by use of a pair of electric wires, in which errors due to voltage drops of the measurement voltages 7 over the transmission line 2 are corrected with measurements of the reference voltages 6 whose voltage is known in advance so that precise analog measurements can be performed.
