Abstract: An implantable medical device includes a detecting unit, a control unit and a communication unit. The control unit uses a seizure prediction algorithm to predict epilepsy seizure events in real time based on physiological information detected by the detecting unit, and stores internal data which comprise the detected physiological information and prediction information about the prediction result. The control unit is configured to, in a first communication mode, control its memory unit and communication unit to transmit the internal data to the external monitoring device, and in a second communication mode, control the communication unit to receive an updated seizure prediction algorithm from the external monitoring device and stores the algorithm in the memory unit for predicting seizure events.

Abstract: A system and method for processing X-ray fluorescence data in a hand-held X-ray Fluorescence (XRF) analyzer are provided. The X-ray fluorescence (XRF) analyzer includes a radiation source assembly including a first centerline axis and configured to direct an X-ray beam to impinge on a sample to be tested. The XRF analyzer also includes a radiation detector assembly including a second centerline axis configured to sense X-ray fluorescence (XRF) emitted from the sample in response to the X-ray beam. The XRF analyzer further includes a processor configured to determine a property of the sample to be tested from the emitted XRF, and a proximity sensor configured to continuously measure a distance between the XRF analyzer and the sample to be tested, the distance being at least one of displayed to a user and used by the processor to determine the property.
