Abstract: Control circuitry for a touch panel includes a touch panel interface, a memory including object classification logic, and a controller in communication with the memory and the touch panel interface. The controller is operable, when the object classification logic is executed, to perform selected processing of the touch panel heat map, including: classifying a touch as a hover touch, finger touch, or stylus touch; rejecting palm or other large object touches; rejecting knuckle touches; rejecting grip touches; and other processing.

Abstract: Certain aspects of the present disclosure relate to a method for estimating a blood pressure using both a pulse arrival time (PAT) and an instantaneous heart rate (HR). The PAT can be measured as the delay between QRS peaks in an electrocardiogram (ECG) signal and corresponding points in a photoplethysmogram (PPG) waveform. Parameters of the estimation model can be determined through an initial training. Then, the model parameters can be recalibrated in constant intervals using the recursive least square (RLS) approach combined with a smooth bias fixing. The proposed estimation algorithm is applied on a multi-parameter intelligent monitoring for intensive care (MIMIC) database, and the results are compared with estimation methods that use PAT only or HR only. The proposed estimation algorithm meets, on average, the Association for the Advancement of Medical Instrumentation (AAMI) requirements and outperforms other methods from the prior art.
