Abstract: Methods for predicting health characteristic may include: obtaining patient medical information that includes protein data; a machine-learning model based on concordance with the characteristic, the patient medical information, a time-frame for prediction, or in the protein data. Different models may have been trained using different groupings of training patient data, trained to predict different characteristics, trained or evaluated using different biomarkers, trained using proteins, protein groups, or protein categories listed in Tables M through R, or evaluated for different time-frames. The selected model may be used to generate the prediction using the patient medical information. A model may be generated by pre-processing medical information, generating an ensemble of models; determining a sensitivity of variables of the medical information to identify a subset of variables; and training a machine-learning model using the subset.

Abstract: An infrared radiation intruder detection system is disclosed which employs a unique pyroelectric detector array. The array comprises a pyroelectric plastic film having electrodes arranged on opposing surfaces to define a plurality of heat-sensitive capacitors connected in parallel. According to a preferred embodiment, the film of selected detector elements is poled to a polarity opposite that of the other elements to cause internal cancellation of signals due to events which affect an even number of detectors simultaneously.
