Abstract: Various examples related to electromagnetic interference (EMI) energy mitigation techniques are provided. In one example, a method includes adjusting switching angles of a switching circuit based on resolution bandwidths (RBWs) associated with an EMI frequency spectrum of the switching circuit and weight coefficients of the RBWs. The total energy of the switching circuit can be reduced by adjusting an average duty cycle of the switching circuit. EMI spectrum information can be determined based upon switching angles of a switching circuit. For example, weighted errors corresponding to differences between reference harmonic magnitudes and determined harmonic magnitudes can be determined. In response to a comparison of a maximum weighted error to a preset tolerance threshold, adjustment to the switching angles can be determined and/or applied.

Abstract: Disclosed is an AMS process using a water-leachable alloy that reacts with water and dissolves, and a porous metal manufactured using the same. An AMS precursor including element groups that are selected in consideration of the relationship of heat of mixing with the water-leachable alloy composition to be subjected to the AMS process is immersed in the alloy melt, thus manufacturing a bi-continuous structure alloy. The bi-continuous structure alloy is subjected to dealloying using water, thus manufacturing the porous metal. The water-leachable alloy is a Ca-based alloy having high reactivity to water and high oxidation resistance at high temperatures, and a dealloying process thereof is performed using only pure water, unlike a conventional dealloying process performed using a toxic etching solution of a strong acid/strong base. The metal porous body has high elongation, a large surface area, and low thermal conductivity.

Abstract: Various examples are provided for highly reconfigurable multiband radio frequency (RF) filters. The multiband RF filters can be continuously tunable. In one example, a multiband RF filter includes a Lyot loop filter that can generate an optical comb using an input optical signal from a tunable Mach-Zehnder interferometer (MZI), a birefringent device, and a polarization rotation angle of a polarization controller. The tunable MZI can include a tunable delay line that can adjust comb spacing of the optical comb. In another example, a multiband RF filter includes a second MZI in series with a first MZI. The second MZI can generate a second tunable output signal from a first tunable output signal from the first MZI. In another example, the multiband RF filter can include a third MZI in series with the second MZI. The third MZI can generate a third tunable output signal from the second tunable output signal.

Abstract: A three-dimensional, head mounted microphone array is employed to isolate and analyze intracranial sound sources such as may provide for objective tinnitus. The microphone array allows a region of interest within the patient's head to be isolated for the detection of sounds and allows episodic sounds to be automatically identified as to location. An interactive display allows a better understanding of sound locations and the extracted sounds can be analyzed with respect to a library of sounds linked to particular locations and diagnoses.

Abstract: Wireless power transmission (WPT) systems are provided. According to an embodiment, the WPT system uses one or more power transmitting coils and a receiver for electromagnetically coupled wireless power transfer. The electrodynamic receiver can be in the form of an electrodynamic transducer where a magnet is allowed to oscillate near a receiving coil to induce a voltage in the receiving coil, a piezoelectric transducer where the magnet causes a vibrating structure with a piezoelectric layer to move, an electrostatic transducer where movement of the magnet causes a capacitor plate to move, or a combination thereof. An alternating magnetic field from the transmitting coil(s) excites the magnet in the receiver into mechanical resonance. The vibrating magnet then functions similar to an energy harvester to induce voltage/current on an internal coil, piezoelectric material, or variable capacitor.

Abstract: Functional electrical stimulation (FES) cycling devices and associated methods are generally described. An FES cycling device may comprise a crank, two or more pedals connected to the crank, one or more sensors adapted to measure position and/or velocity of the crank, and one or more electrodes configured to deliver electrical stimulation to a person associated with the cycling device. In some cases, the FES cycling device further comprises a controller configured to receive input signals from the one or more sensors and deliver output signals to the one or more electrodes. In certain cases, the controller may dynamically generate a control signal to deliver an amount of electrical stimulation to a muscle group (e.g., quadriceps femoris, gluteal muscles, hamstring muscles) based on the value of a determined torque transfer ratio between a joint of the person and the crank of the cycling device. The electrical stimulation may, in some cases, cause the person to pedal the cycling device.
