摘要： The invention generally relates to ion traps and methods of use thereof. In certain embodiments, the invention provides a system that includes a mass spectrometer including an ion trap, and a central processing unit (CPU). The CPU has storage that is coupled to the CPU for storing instructions that when executed by the CPU cause the system to apply a constant radio frequency (RF) signal to the ion trap, and apply a first alternating current (AC) signal to the ion trap the frequency of which varies as a function of time.

摘要： A method for imaging a sample, wherein the sample changes a polarization state of light as a function of position, wherein the method includes changing a polarization state of a purely polarized light of an incident light striking a micro-retarder array, thereby inducing a changed polarization state of the polarization state. The micro-retarder array is placed in a rear conjugate focal plane of a microscope. The method additionally includes projecting the changed polarization state of the polarization state into an object plane of the microscope containing the sample.

摘要： The disclosure relates to particle heaters for heating solid particles to store electrical energy as thermal energy. Thermal energy storage directly converts off-peak electricity into heat for thermal energy storage, which may be converted back to electricity, for example during peak-hour power generation. The particle heater is an integral part of an electro-thermal energy storage system, as it enables the conversion of electrical energy into thermal energy. As described herein, particle heater designs are described that provide efficient heating of solid particles in an efficient and compact configuration to achieve high energy density and low cost.

摘要： The invention generally relates to mass tag analysis for rare cells and cell free molecules. In certain embodiments, the invention provides an apparatus including an essentially non-absorbent membrane having at least one pore, a microwell operably associated with the essentially non-absorbent membrane, and an electric field generator. The apparatus may be configured such that an electric field produced by the electric field generator operably interacts with a sample in the microwell and expels a droplet of the sample through the at least one pore in the essentially non-absorbent membrane. In certain embodiments, apparatuses of the invention are used for detection, and optionally quantification, of a target analyte from a heterogeneous sample, such as a rare target analyte (e.g., rare cell) from a biological sample.

摘要： Boresight and lever arm calibration of cameras and scanners on UAVs or mobile platforms is performed by optimizing the flight/travel path of the UAV/platform relative to control points or tie points. The flight/travel paths account for the potential bias of boresight angles, lever arm and times delays to produce an accurate estimation of the orientation of these cameras/scanners relative to the GNSS/INS coordinate system of the UAV/platform.
