  • Patent number: 10505094
    Abstract: Superconducting nanowire avalanche photodetectors (SNAPs) have using meandering nanowires to detect incident photons. When a superconducting nanowire absorbs a photon, it switches from a superconducting state to a resistive state, producing a change in voltage that can be measured across the nanowire. A SNAP may include multiple nanowires in order to increase the fill factor of the SNAP's active area and the SNAP's detection efficiency. But using multiple meandering nanowires to achieve high fill-factor in SNAPs can lead to current crowding at bends in the nanowires. This current crowding degrades SNAP performance by decreasing the switching current, which the current at which the nanowire transitions from a superconducting state to a resistive state. Fortunately, staggering the bends in the nanowires reduces current crowding, increasing the nanowire switching current, which in turn increases the SNAP dynamic range.

  • Patent number: 10426889
    Abstract: An optical sensor for a delivery device having a piston that displaces a substance, such as a fluid, from a reservoir. The optical sensor has a light source and a detector array for imaging encoding features disposed along a plunger rod coupled to the piston. By virtue of the pattern of encoding features, an absolute position of the plunger rod relative to a fiducial position may be determined uniquely. Thus, the volume of fluid remaining in the reservoir, the rate of fluid delivery, and proper loading of the reservoir may be accurately ascertained. Additionally, the encoding may serve to uniquely identify a version of the reservoir which may be supplied in various versions corresponding, for example, to differing concentrations of a therapeutic agent to be dispensed.
