Publication number: 20160247043Abstract: Large-area electronics (LAE) enables the formation of a large number of sensors capable of spanning dimensions on the order of square meters. An example is X-ray imagers, which have been scaling both in dimension and number of sensors, today reaching millions of pixels. However, processing of the sensor data requires interfacing thousands of signals to CMOS ICs, because the implementation of complex functions in LAE has proven unviable due to the low electrical performance and inherent variability of the active devices available, namely amorphous silicon (a-Si) thin-film transistors (TFTs) on glass. Envisioning applications that perform sensing on even greater scales, disclosed is an approach whereby high-quality image detection is performed directly in the LAE domain using TFTs. The high variability and number of process defects affecting both the TFTs and sensors are overcome using a machine-learning algorithm, known as Error-Adaptive Classifier Boosting (EACB), to form an embedded classifier.Type: ApplicationFiled: February 19, 2016Publication date: August 25, 2016Inventors: Warren Rieutort-Louis, Tiffany Moy, Zhuo Wang, Naveen Verma, Sigurd Wagner, James C.

Publication number: 20130080808Abstract: A biomedical device for comprehensive and a data-driven patient monitoring is disclosed. The biomedical device includes a receiver to receive sensor data associated with physiological signals and perform feature computations on the sensor data. A control system is included to classify the sensor data using the feature computations to generate medically-relevant decisions and identify relevant data instances, and to automatically select a set of relevant data instances. A base station or programming interface can provide a patient-generic seed model to the biomedical device. The patient-specific seed model is usable by the control system to automatically select a coarse set of relevant data instances that are transmitted to the base station, which in turn analyzes the coarse set of relevant data instances to generate a patient-specific model. The biomedical device receives the patient-specific model, which is usable by the control system to automatically select a refined set of relevant data instances.Type: ApplicationFiled: September 28, 2011Publication date: March 28, 2013Applicant: THE TRUSTEES OF PRINCETON UNIVERSITYInventors: Naveen Verma, Kyong Ho Lee
