    摘要： A new and distinct cultivar of Vaccinium plant named ‘NC4499’ is disclosed, characterized by attractive glaucous light blue-green foliage, and self-pollinating flowers developing into light blue fruit. Fruit is juicy and sweet. The new variety shows long-term survival under field conditions, and a heightened resistance to blueberry leaf rust. Plants are semi-evergreen in the Southeastern United States and maintain an attractive tidy shape long-term, including without pruning. Plants are suitable for pruning. The new variety is a Vaccinium, normally used as an ornamental garden or landscape plant.

    摘要： The present invention provides wearable plant sensors for continuous monitoring of plant physiology by tracking both biochemical and biophysical signals of the plant and its microenvironment. Sensors for detecting volatile organic compounds (VOC), temperature, and humidity are integrated into a single platform. The abaxial leaf attachment position is selected based on the stomata density to improve the sensor signal strength. This versatile platform enables various stress monitoring applications, ranging from tracking plant water loss to early detection of plant pathogens. A machine learning model was also developed to analyze multichannel sensor data for quantitative detection of tomato spotted wilt virus (TSWV) as early as four days after inoculation.

    摘要： A power device includes a packaged semiconductor switch containing first and second series-connected insulated-gate transistors, first and second control terminals electrically connected to the first and second insulated-gate transistors, respectively, first and second current carrying terminals electrically connected to the first and second insulated-gate transistors, respectively, and a voltage-monitoring terminal electrically connected to an internal node shared by first and second current carrying regions within the first and second insulated-gate transistors, respectively. The first and second control terminals can be electrically connected to a gate of the first insulated-gate transistor and a gate of the second insulated-gate transistor, respectively; and the first and second current carrying terminals can be electrically connected to a source of the first insulated-gate transistor and a drain (or collector) of the second insulated-gate transistor. The voltage-monitoring terminal is electrically connected to a drain of the first insulated-gate transistor and a source (or emitter) of the second insulated-gate transistor.

    摘要： Various examples are provided related to transformer designs that offer very high isolation while maintaining high coupling between the windings. In one example, an isolation transformer includes a first excitation coil wound around a first core and a second excitation coil wound about a second core. The second core is electrically separated from the first core by a high resistivity magnetic material or a non-conductive material. The first and second cores can include corresponding core segments arranged in a trident geometry or a quindent geometry. The core segments can align when the first excitation coil is inserted into a void of the second excitation coil. The isolation transformer designs are mechanically separable which can result in safe, energized, plug operations.

    摘要： A system for estimating moisture in soil includes a first antenna for transmitting RF signals, second antennas for receiving RF signals, and a controller configured to: emit, via the first antenna, RF signals at a plurality of frequency increments; determine a channel frequency response (CFR) based on amplitude attenuation and phase change of reflected RF signals detected by the second antennas; determine a power delay profile (PDP) for the second antennas based on the CFRs; extract a subset of the reflected RF signals using peak detection on the PDPs; and for each layer of the soil and for each of the subset of reflected RF signals, determine: i) a wavelength of the reflected RF signal in the layer, ii) an estimated depth of the layer, iii) a dielectric permittivity of the layer based on the wavelength, and iv) an estimated moisture content of the layer based on the dielectric permittivity.
