Methods and Systems for semi-automatic adjustment of medical monitoring and treatment
ActiveUS20080097553A1Good treatment effectConvenient treatmentDrug and medicationsMedical devicesDiseaseMedical disorder
Systems and methods are described for adjusting the operation of implantable stimulation devices used to provide medical monitoring and treatment. Several hierarchical algorithms are described which operate according to conditionally obtaining a patient response to an alert signal. In one such strategy semi-automatic therapy adjustment occurs by automatically issuing patient alert messages when selected operations are to occur, and using a patient's response to the alert message that is provided within a selected time limit in order to contingently adjust therapy. Methods are also described for resolving conflicts which may occur when time information and sensed data information each indicate different patient states are occurring. Although treatment of neural and cardiac disorders is emphasized, the techniques can be applied to the monitoring and treatment of any medical disorder with an implanted device.

Combined modulation recognition method based on clustering and support vector machine
InactiveCN102497343AImprove recognition rateImprove modulation recognition ratePhase-modulated carrier systemsMultiple carrier systemsPattern recognitionCluster algorithm
The invention provides a combined modulation recognition method based on clustering and a support vector machine in order to overcome the shortcoming of low modulation recognition rate of a clustering algorithm with a low signal to noise ratio. According to the method, a characteristic parameter of a modulation signal is extracted by using the clustering algorithm according to a phase shift keying / quadrature amplitude modulation (PSK / QAM) mode based on a constellation diagram; and a modulation mode for a signal is recognized through the support vector machine, so that the modulation recognition rate of a system is increased. The method comprises the following steps of: aiming at the PSK / QAM mode based on the constellation diagram, reconstructing the constellation diagram of a receiving signal by using the clustering algorithm; and obtaining an effective function value, which can reflect an outstanding difference of modulation types under different clustering central numbers, as the characteristic parameter input into the support vector machine by constructing an effectiveness evaluation function. In order to overcome the shortcoming that two common algorithms of one to multiple and one to one have high calculation complexity when the support vector machine recognizes multiple types, the support vector machine is trained by adopting a hierarchical algorithm.
