  • Patent number: 9168354
    Abstract: A protective catheter tip has a generally tubular body portion defining an interior cavity. The proximal end of a urinary catheter is at least partially received within the protective tip, with the protective tip being retained on the urinary catheter without the need for a sleeve connecting the protective tip and the catheter. The protective tip may include a projection received within a draining hole or eye at the proximal end of the catheter to retain the protective tip on the catheter. The protective tip may instead include one or more projections that apply a frictional force to an outer surface of the catheter to retain the protective tip on the catheter. The protective tip may instead be retained on the catheter by a tether extending between the protective tip and a distal end of the catheter. The protective tip may also include two separate or separable pieces.

  • Patent number: 8716647
    Abstract: An analog silicon photomultiplier system includes at least one analog pixel comprising a plurality of analog photodiodes (APDs), and a capacitor, a signal generator, a phase detector, and a compensation network. The signal generator is configured to generate and propagate a sinusoidal signal concurrently along first and second transmission lines. A capacitor is loaded on the first transmission line when an APD corresponding to the capacitor detects a photon. The phase detector is coupled with the first and second transmission lines, determines a phase difference between the first transmission line and the second transmission line and calculates a number of APDs that have fired from the phase difference. The compensation network is coupled with the second transmission line and the phase detector, and comprises a plurality of compensation capacitors, wherein the compensation capacitors are loaded on the second transmission line in proportion to the number of APDs that have fired.

  • Patent number: 8264678
    Abstract: A light sensor and light sensing system to detect an intensity of incident light and an angle of incidence of the incident light. The light sensor includes a dielectric layer, a plurality of photo detectors coupled relative to the dielectric layer, and a plurality of stacks of opaque slats embedded within the dielectric layer. The dielectric layer is substantially transparent to the incident light. The photo detectors detect the incident light through the dielectric layer. The stacks of opaque slats are approximately parallel to an interface between the dielectric layer and the photo detectors. The stacks of opaque slats define light apertures between adjacent stacks of opaque slats. At least some of the stacks of opaque slats are arranged at a non-zero angle relative to other stacks of the opaque slats.
