A method, a non-transitory computer readable medium and a system for compensating for an electromagnetic interference induced deviation of an electron beam. The method may include obtaining measurement information about a magnetic field within an electron beam tool, the measurement information is generated by at least one planar Hall Effect magnetic sensor that is located within the electron beam tool; wherein the at least one planar Hall Effect magnetic sensor comprises at least one magnetometer integrated with at least one magnetic flux concentrator; estimating the electromagnetic interference induced deviation of the electron beam, the estimating is based on the magnetic field; and setting a trajectory of the electron beam to compensate for the electromagnetic interference induced deviation of the electron beam.

The demand for computational performance continues to rise exponentially, while power and thermal budgets impose strict limitations on integrated circuits (ICs). Modern processors employ multiple power domains, each requiring accurate current sensing for efficient power management. Existing current sensing techniques—such as shunt, Hall-effect, and fluxgate sensors—are either too large, too power-hungry, or too slow for integration at the scale of tens or hundreds of domains within a single chip. Digital ring-oscillator (RO) sensors have been explored, but they exhibit strong non-linearity, temperature, and supply dependence, which severely limit their accuracy. This research proposes a fundamentally new approach: a differential current-controlled oscillator (CCO) amplifier, which directly converts differential current or voltage into a frequency domain signal. Unlike conventional amplifiers, the CCO itself acts as both amplifier and analog-to-frequency converter, providing a highly compact, low-power, and fast solution suitable for power-gate current sensing in advanced processors. The proposed sensor targets an accuracy better than 0.2%, conversion time below 2 μs, power consumption under 20 μW, and area smaller than 0.01 mm², yet with performance significantly surpassing existing state of-the-art designs. Novel circuit techniques are introduced for non-linearity correction, temperature compensation, and common-mode rejection, including bias trimming, replica oscillators, and chopper stabilization. Preliminary simulations of a 65nm implementation demonstrate excellent linearity, 60 dB dynamic range, and temperature- and supply-induced variation below 0.02% when using replica compensation. This project will establish a new class of analog amplifiers based on differential CCOs, enabling fine-grained, energy-efficient current sensing for multi-domain processors, GPUs, and AI accelerators. The outcomes are expected to impact both industrial and academic fields by providing a compact, low-cost, low power sensing solution for power-management architectures and extending its use to applications such as biomedical monitoring, smart-grid systems, and energy-harvesting circuits.

We previously introduced a method and device for significantly enhancing the resolution of Raman spectroscopy measurements by using angle tuning of a Fabry-Perot (F-P) etalon in the beam path of a standard grating-based dispersive Raman spectrometer. Building on this innovation, we propose a novel configuration where Raman filters are placed after the F-P etalon. This configuration allows the F-P etalon to interact with both the coherent laser line and the excited Raman signal, enabling simultaneous measurement of the laser's spectral peak position and linewidth along with the stimulated Raman peak. By leveraging this dual measurement, we achieve simultaneous super-spectral-resolution of the Raman peak and the laser's spectral position, leading to an enhanced-resolution and determination of the absolute Raman peak shift, with both the laser and Raman peaks being super-resolved simultaneously. The method relies on computationally reconstructing the peak positions and linewidths of both the laser excitation and Raman scattering by comparing their angle-dependent intensity spectra to a physical model. The reconstruction provides ultra-high resolution for the linewidths and positions of both laser and Raman peaks in the same measurement, which can be achieved either by using a wide-enough range dispersive grating or by separately measuring the reflected or scattered laser signal with a photodetector. When analyzing a substance with a known Raman spectrum, this dual-measurement approach enables highly precise scattering spectroscopy using much more compact instrumentation. By combining the angle-dependent spectra from the Fabry-Perot etalon with a physical model, this method offers a streamlined and cost-effective solution for high-resolution spectral analysis, making it particularly advantageous for applications requiring compact and efficient setups. When analyzing a substance with a known single Raman peak, this dual-measurement approach enables highly precise scattering spectroscopy using just a pair of photodetectors, effectively eliminating the need for a full spectrometer. By combining the angle-dependent spectra from the Fabry-Perot etalon with a physical model, this method offers a streamlined and cost-effective solution for high-resolution spectral analysis, making it particularly advantageous for applications requiring super-compact and efficient setups.

The growing prevalence of large-scale sensor networks calls for direction-of-arrival (DOA) estimation methods that operate under stringent communication constraints. In this discovery, we show that DOA can be reliably inferred when each remote sensor conveys only extremum indices of its observations, requiring just a few bits. Using these indices, the fusion center computes a steered-response-power-like criterion, whose maximizer is a consistent DOA estimator. Simulations reveal that our method approaches the accuracy of a theoretical rate-distortion-based benchmark while requiring dramatically fewer bits than conventional compression followed by classical DOA methods.

State-of-the-art receivers in wireless charging for electric vehicles consist of horizontal coils (where the coil plane is parallel to the road). We propose a revolutionary coil configuration which maximizes flux collection in the receiving coils. This configuration consists of coils vertically situated to the magnetic flux with a ferromagnetic core within the coils. The magnetic core on which the vertical coils are wound, support the enhancement of flux collection while keeping the height of the coils limited as required. This innovation has been proved for its feasibility and advantageous in simulation based studies as well as in downscaled experimental model.

The invention provides a method for designing and implementing frequency-domain filter functions in quantum systems through dynamically invariant control fields. Unlike traditional dynamical decoupling methods, which derive spectral properties post hoc from time-domain sequences, this method analytically constructs time-dependent Hamiltonians that realize arbitrary spectral responses, including multi-band and phase-sensitive profiles. The approach utilizes the formalism of dynamical invariants to ensure exact state evolution and robustness to drive-amplitude errors. Experimental implementation on nitrogen-vacancy (NV) centers in diamond demonstrates enhanced coherence preservation and signal selectivity beyond conventional control protocols.

The present invention relates to optical and quantum sensing systems that utilize synthetic temporal gauge fields to perform ultrafast and noise-resilient measurements. More specifically, the invention describes an interferometric sensing architecture in which an external signal is converted into a gauge-invariant temporal phase, analogous to a temporal Aharonov–Bohm (AB) effect, and is subsequently measured through interferometric or correlation-based detection. In the disclosed system, correlated optical modes are generated using a parametric process, such as four-wave mixing or parametric amplification, forming a temporal interferometric structure. The optical modes propagate through a dispersive or time-lens-based section, in which a time-dependent modulation is applied. This modulation produces a synthetic temporal gauge potential that induces a relative phase shift between the correlated modes. The accumulated phase depends on the temporal profile of the modulation and constitutes a gauge-invariant quantity analogous to the Aharonov–Bohm phase in conventional electromagnetic systems. After the gauge-induced phase is acquired, the optical modes are recombined in a second parametric or interferometric stage. The output signal depends on the accumulated gauge phase and is detected using intensity, interferometric, or correlation-based measurements. Because the sensed quantity is a gauge-invariant phase, the system exhibits reduced sensitivity to local perturbations, amplitude noise, and certain environmental fluctuations, thereby enabling more robust and accurate measurements. The invention enables sensing of a wide variety of external signals, including but not limited to: ultrafast phase or delay variations, time-dependent electrical or optical modulation signals, radio-frequency or microwave waveforms, dynamic optical path variations. The sensing mechanism is fundamentally different from conventional phase or amplitude modulation techniques, as the measured signal is encoded in a synthetic gauge phase rather than in a local field interaction. This approach allows ultrafast operation, compatibility with both classical and quantum optical regimes, and the possibility of enhanced sensitivity through parametric or correlation-based readout. The disclosed architecture may be implemented using temporal SU(1,1) interferometers, time-lens systems, dispersive optical elements, electro-optic modulators, or other time-dependent phase modulation devices. The system can operate with classical optical fields, single photons, or entangled photon pairs, and may be configured for various sensing, metrology, and signal-processing applications.

This invention proposes a scalable and variation-aware algorithm for skew balancing of digital circuits. The skew balancing has two main objectives: the application of clockless wave-propagated pipelining (CWPP) and the reduction of dynamic glitch power. The algorithm achieves the balancing of the maximum and minimum delays through all internal gates of a combanatorial block by iteratively applying delays to the faster paths, while overcoming variation by using a skew balanced strobe signal for output capture.

The invention is an electromagnetic active protection system, designed to neutralize kinetic energy penetrators (such as armor-piercing rods) before they strike a vehicle's main armor. The system consists of an array of charged conductive plates; when a projectile traverses the array, it physically bridges the gap between electrodes, acting as a closing switch to trigger a rapid, high-current electrical pulse. This discharge exploits the "skin effect" to concentrate intense heat specifically at the projectile's tip, softening it significantly, while simultaneously generating an asymmetric Lorentz force that induces a yaw (tilt) angle. The combination of tip softening, shear stresses from differential thermal expansion, and mechanical tumbling causes the projectile to fracture or shatter upon impact, drastically reducing its penetration capability.
