Abstract: A device has a body defining a space for the passage of a fluid, as well as a detector of a hydraulic or chemical-physical property of the fluid in the space. The detector is connected to a control unit by means of a wireless communication system that includes a data transmission circuit, connected to the detector, and a data receiving circuit, interfaced to the control unit. The wireless communication system includes a radio-frequency passive electric circuit without independent power supply.

Abstract: A device for controlling or preparing a mixture of fluids, in particular a food or domestic mixture, comprises at least two addition ducts for a first and a second fluid getting in (5B), an area where the two fluids are mixed (23), so as to obtain a mixture getting out, and control means (SC) for flow rate adjusting elements (13B) for the first and second fluid, arranged on the addition ducts. The invention envisages detecting means (29) for one or more physical-chemical properties of at least one among said mixture, first fluid and second fluid. In a preferred embodiment the detected physical-chemical quantity is pH.

Abstract: A device (1) comprises a body (E1, E2) defining a space (P) for the passage of a fluid, detecting means (32?) for at least a hydraulic or chemical-physical property of the fluid passing through said space (P), and a control system. The connection between the detecting means (32?) and the control system comprises a wireless data transmission circuit (SWG) connected to the detecting means (32?), and a corresponding receiving circuit (RWG) interfaced to the control system. The transmission system can advantageously be a radio-frequency passive electric circuit (34, 36) without independent power supply.

Abstract: Household apparatus using a fluid, comprising a purifying system in which at least a substance must be removed from at least a portion of said fluid, said system comprising: an electrochemical, electro-dialysis or electro-osmosis cell (20); collecting means (P,S,AC) of said fluid; controlling means (SCE). According to the invention, recycle means are provided (12,22,23,15,21,24), to realize a substantially closed circuit and/or continuous circulation of said fluid between the collecting means (P,S) and said cell (20), until a preset purifying value of the fluid is reached.

Abstract: Arrangement for electrochemical purification or treatment of a liquid, utilizing an electrochemical cell (20), where two electrodes (20B,20C) are provided with ion exchange membranes (C,A) arranged between them to delimit a plurality of channels (CE,CC,CP). According to the invention, at least a few channels (CE,CC,CP) have respective second electrodes (+,−) associated to them for obtaining a cleaning substance or solution, the latter being apt to dissolve and/or remove likely residuals and/or scaling deposited inside the cell (20).

Abstract: A mobile station decreases its transmit bit rate in response to a determination that its transmit power has exceeded an alarm-power threshold. The mobile station increases its bit rate in response to a determination that its transmit power is below a lower-power threshold. Lower-power threshold and alarm-power threshold delays can be employed to prevent ping-pong effects and avoid unnecessary throughput degradation. A dynamic lower-power threshold can be employed in which the mobile station estimates or predicts its transmit power if it were to increase its transmit bit rate and increases its transmit bit rate only if this can be performed without exceeding the alarm-power threshold.
