Abstract: An active medical device, in particular an implantable device such as a cardiac pacemaker, defibrillator, cardioverter, or multisite device, including a function for determining sleep disorders. This device can collect the heartbeat rhythm in at least one heart cavity, and analyze the collected rhythm so as to evaluate a value of heartbeat rate accordingly. The device can also discriminate within a collected heart rhythm the spontaneous events of sinusal origin, and to evaluate the heart rate according only to these spontaneous sinusal events, and to analyze the time variations of the aforementioned heart rate to determine the presence of a sleep respiratory disorder accordingly. This analysis can be realized through a search for episodes of bradycardia followed by episodes of tachycardia, or by determination of an index of sinusal variability that is a function of the detected variations, and comparison of this index with a predetermined threshold.

Abstract: The invention relates to a reconfigurable device comprising a plurality of processing devices, a connection matrix providing an interconnect between the processing devices, and means to define the configuration of the connection matrix. Each of the processing devices comprises an arithmetic logic unit, which is adapted to perform a function on input operands and produce an output. The input operands are provided as inputs to the arithmetic logic unit from the interconnect on the same route in each cycle. Dynamic instructions are enabled by means provided to route the output of a first one of the processing devices to a second one of the processing devices to determine the function performed by the second one of the processing devices.
