Abstract: A sensing and processing electronic circuit includes a sensing array having a plurality of sensing elements each having a sensor configured to produce an output signal in response to detection of an environmental parameter. The circuit includes a triggering unit configured to generate a trigger signal that causes an action to occur. The trigger signal is generated based on selected activated sensing elements satisfying one or more specifiable conditions. A sensing element is activated when a characteristic value based on the output value of the sensing element crosses one or more thresholds so that the characteristic value is above, below, within or outside of a specified range of values or when a difference value between the characteristic value and a previous or template value of the sensing element crosses one or more thresholds so that the difference value is above, below, within or outside of a specified range of values.

Abstract: Provided are systems, compositions and methods that useful in any setting where generating and tracking light is used. The systems, methods and compositions contain as a component flexible, transparent membrane-based materials that include light emitting diodes (LEDs). The LEDs can include or be formed from colloidal quantum dots (CQDs) as an active layer. The CQDs can be formed from solution-processed semiconductor nanocrystals. They have a tunable band gap energy that can be readily tuned by adjusting the size of the nanocrystals. Transparent membrane-based LED arrays exhibit emission wavelength that can be tuned anywhere in the range of 800-2000 nm. The LEDs are highly transparent in the visible wavelength range with the exception of the CQD active layer. The CQD-based LEDs are components of any device or system wherein generating and/or tracking reflected light is utilized, such as in tracing the location and movement of a living individual, or an inanimate object.
