    Abstract: Disclosed is an energy mixer having a first active diode coupled between a first input node and an output node, and a second active diode coupled between a second input node and the output node. A first capacitor is coupled between the first input node and a dynamic node, and a second capacitor is coupled between the second input node and a third node. Switching circuitry is configured to selectively couple the dynamic node between a fixed voltage node and the second input node in response to a control signal provided by control circuitry. When an output voltage at the output node is within a first range, the dynamic node is coupled to the fixed voltage node and when the output voltage is within a lower voltage second range, the dynamic node is coupled to the second input node such that first capacitor and second capacitor are coupled in series.

    Abstract: A device and method for detecting COVID-19 and other pathogens includes a sample compartment contained within an interior of the device and having multiple apertures for releasably receiving one or more test tubes containing a biological sample. A bottom portion of the test tube is contained within the interior of the device and a top portion of the test tube is exposed to atmosphere. The biological sample is lysed using the device; the lysed sample is mixed with one or more primers and then amplification (RT-LAMP) is performed using the device. A thermally conductive material on or in proximity to the sample compartment can facilitate precise heating of the compartment and sample. A thermally insulative material can be inside the interior of the housing. Multiple samples can be tested simultaneously. The results can be interpreted by a color change of the sample. The device is efficient, portable, reliable, and re-usable.

    Abstract: Techniques for measuring vacuum pressure using a memristor element are described. A vacuum sensor can include a memristor element having a semiconductor substrate, a memristive material layer, and a conductive electrode. The off-state resistance of the memristor element can be sensitive to changes in ambient pressure at the element. The off-state resistance of the memristor element may also exhibit a well-defined increase at pressures below a threshold pressure. Measurement of the off-state resistance may be obtained with low power consumption and without changing the resistance or switching the state of the memristor element. The measurements may be used to both determine a leak rate of the ambient pressure within the volume of interest and determine if the sensor is exposed to vacuum pressure below the threshold pressure.
