Abstract:
The invention relates to a system for transmitting power inductively from a transmitter (11) to a receiver (10), the receiver (10) comprising a signal generator for generating a signal, triggered by an event reflecting that the receiver intends to receive power from the transmitter, wherein said signal intends to activate said transmitter from standby mode to activated mode; and comprising a signal transmitting coil (103) for transmitting said signal to said transmitter; said transmitter (11) comprising a signal receiving coil (112); a detector (114) for detecting said signal received by the receiving coil; and a unit (115) for activating the transmitter from standby mode to activated mode upon the detection of said signal.
Abstract:
The apparatus allows the detection of light bubbles in the area of the pressurized fluid chamber or the nozzle of the micro-jet to detect bubbles by light scattering. Light is sent through the area of interest and detected behind it by a light detector. If the light intensity drops correspondingly a drop in the detector current is detected. This is indicative of unwanted bubbles. In this case the actuation of the electromechanical actuator to generate micro-jets may be stopped, alternatively or in additional signal may be output in order to inform a user to replace a fluid reservoir, or to simply issue an alarm. The fluid delivery device may comprise a durable and a disposable section, wherein the active parts such as power source, light source and light detector are integrated in the durable section and the disposable section comprises a nozzle and the fluid chamber which presents significant advantages, as the contact interface to the skin is frequently replaced and thus hygienic conditions are easy to maintain.
