Abstract: The invention relates to methods and kits for detecting one or more antibody biomarkers in a sample, wherein the antibody biomarker specifically binds a viral antigen. In embodiments, the viral antigen is a monkeypox virus (MPXV) antigen, a vaccinia virus (VACV) antigen, or combination thereof.

Abstract: A two-terminal integrated circuit magnetic-field detector, for use in detecting a low level of a liquid in a vehicle, has a Hall element, a Schmitt type comparator, an anti-sloshing accumulator such as an up-down counter, and a latching driver all connected in tandem. The anti-sloshing accumulator is for producing a signal that is the integral as a function of time of the binary comparator output signal. During sloshing, when the average liquid level is near that at which a low-level warning signal is desired, the accumulator signal climbs in a vacillating manner. The latching driver is connected across the two integrated circuit (I.C.) terminals and latches on when the accumulator signal reaches a predetermined value, dropping the impedance across the two I.C terminals. A liquid level indicating lamp is connected in series with a source of DC voltage and the two I.C. terminals, so that when the average position of the floating magnet approaches that of the I.C.

Abstract: A low power magnetic-field detector, of the kind for detecting an ambient magnetic field that is greater than a predetermined field strength, is comprised of a Hail element, a transducer-voltage amplifier, and a zero-crossing comparator, all connected in tandem. A clock and switch are used to chop the energizing current to the Hall element. Alternatively, the amplifier and comparator are also chopped to further reduce power consumption. A clockable flip flop is synchronously enabled for an instant at the end of each period of energizing the Hall element. The comparator output signal is transferred to the flip flop Q output and held there during each period of not energizing the Hall element. A Positive-feedback hysteresis circuit adds a bias voltage to the amplified Hall voltage and is applied to the comparator input to effect comparator hysteresis with memory covering clock-period portions when the Hall element is not energized.
