An apparatus to remove ions, the apparatus including an inlet to let water in the apparatus; an outlet to let water out of the apparatus; a capacitor; and a spacer to separate a first and a second electrode of the capacitor and to allow water to flow in between the electrodes. The apparatus further including a power converter configured to convert a supply voltage of a power source to a charging voltage to charge the capacitor. The power converter is constructed and arranged to recover energy from the capacitor by converting the voltage on the capacitor to supply voltage of the power source.

Systems, methods for manufacturing, and devices for producing an output current that simulates a current generated by an optical patient sensor are provided. An optical patient sensor includes a sensor light source having a first characteristic profile and a sensor photodetector having a second characteristic profile. The current source includes a light source having a characteristic profile similar to the first characteristic profile and indicative of interchangeability between the light source and the sensor light source, and a first photodetector configured to produce an output current in response to receiving light from the light source, the first photodetector having a characteristic profile similar to the second characteristic profile and indicative of interchangeability between the sensor photodetector and the first photodetector.

Low-noise optical current source

A system is disclosed for monitoring the position of one or more RFID tags . The system has a detector incorporating circuitry for detecting changes in the range of an RFID tag from the detector and for triggering an alarm if a detected change in range of an RFID tag exceeds a predetermined threshold or if the RFID radio tag cannot be detected by the detector . Range may be detected, for example, by measuring the time of a returned radio signal from a tag , by measuring the strength of a returned radio signal from a tag, or by detecting changes in a periodic interval at which energy is transmitted by a tag.
