    摘要： An active implantable medical device for neurostimulation therapy is disclosed. The device produces stimulation pulse sequences generated continuously in succession during activity periods separated by intermediate inactivity periods during which no stimulation is issued. An input signal, provided by a physiological sensor, representative of cardiac activity and/or of the patient's hemodynamic status is received by circuitry. The circuitry further provides for dynamic control of the neurostimulation therapy, wherein the length of activity periods is modulated based on the current value level of the control parameter compared to a threshold. The duration of the next period of inactivity is calculated by the circuitry at the end of each activity period to maintain a constant duty cycle ratio between periods of activity and periods of inactivity.

    摘要： The invention relates to a device (LIGHT) for lighting a graphic and/or textual content present on any medium and in particular on a paper medium. The lighting device (LIGHT) is configured to periodically activate and deactivate said lighting beam in successive cycles carried out at a preset frequency Fd. Each cycle has a duration T and comprises a period of activation of the light beam of duration T1 followed by a period of deactivation of the light beam of duration T2 or vice versa. The frequency Fd is comprised in an interval of values ranging from 60 to 90 Hz and the duration T1 of the periods of activation of the light beam is comprised in an interval of values ranging from 15 to 30% of the duration T of the cycles.
