A circuit and a related method to sense the inductor current of CD / DC buck converters have been achieved. The inductor current is sensed by generation of a voltage drop across a fully integrated sense resistor. The voltage drop is proportional to the inductor current in the pass device by supplying a fraction of the inductor current out of a source-follower, which matches to the pass device. The source of said source-follower is connected to a sense-resistor that is connected to the same supply as the pass device. The current, which is needed to generate the voltage drop, is fed back into the inductor current minimizing therefore the efficiency loss. Mirroring, amplification and offset correction of the voltage drop across the sense-resistor is performed by using a single matching pair of source-follower, which is supplied by a current tracking the internal reference voltage and the process variations of the resistors.

The present invention relates to a class of fluorescent, organic nanofibrils, and particularly the films comprising entangled piling of these nanofibrils exhibiting effective quenching of their fluorescence upon exposure the vapor of explosives. The invention also relates to a sensor and a method for sensing the explosives vapor and other volatile organic compounds, including the explosives taggants through the modulation of the fluorescence of the nanofibril film and the electrical conductivity of the nanofibrils. The invention also relates to a development of synthetic methods, protocols and techniques that leads to production of various arylene-ethynylene macrocycle (AEM) molecules, which consist of a shape-persistent, toroidal scaffold in planar conformation, with minimal ring strain and highly tunable ring sizes (from 0.5 nm to above 10 nm). The invention also relates to an approach to optimization of the one-dimensional molecular arrangement along the long axis of the nanofibril, which provides increased exciton (excited state) migration (via cofacial intermolecular electronic coupling) and charge transport (via pi-electronic delocalization). A combination of long-range exciton migration and efficient charge transport makes the nanofibrils ideal as sensory materials for detecting explosives and other volatile organic compounds through both optical and electrical sensing mechanisms.

The display is configured to display an image and comprises a touch sensor for touch input during an assigned sensing section. The controller is configured to perform an operation corresponding to the touch input sensed during the sensing section, and to control the touch sensor to adjust the sensing section based on conditions for adjusting the sensing section. With this, the display apparatus and a control method thereof which can efficiently sense, without lowering the speed of sensing, a touch input based on a plurality of pens or fingers is provided.

Apparatus for detecting the breaking of a contact-sensitive surface includes an acoustic, shock, and vibration transducer, a detector circuit responsive to the transducer for detecting an acoustic wave resulting from a contact force applied to the surface and generating a signal, a support for the transducer, and the means for disqualifying a contact force to the support as a breakage event that relies on differentiation of the speed with which a shock wave travels through a solid material versus the speed with which an acoustic wave travels through air. The transducer may include a front electret condenser microphone and in some preferred embodiments the microphone does not have a preamplifier associated therewith.
