Abstract: The eye imaging system for producing images with reduced speckle artifacts may comprise a laser diode for providing a beam of radiation to the eye; a detector for collecting light returning from the eye and generating output signals in response thereto, the detector having a sensor integration time; a driver circuit for applying a modulated drive signal to the laser diode, the modulated drive signal inducing a spectral broadening of the beam of radiation during the sensor integration time. The laser diode may be a single-mode laser designed to operate at a fixed current and wavelength. The drive signal may be modulated by shaping a drive current pulse. The drive signal may be modulated by imposing an RF modulation on a drive current pulse. The drive signal may be further modulated by shaping a drive current pulse.

Abstract: A safety valve is configured for use at temperatures at or above 760° C. (1400° F.). The safety valve includes a closure assembly that can create a self-energizing, metal-to-metal seal. In one implementation, this closure assembly includes a disc with an arcuate finger that circumscribes an axis of fluid flow through a seat. The arcuate finger may extend inwardly toward this axis and downwardly toward the seat. This geometry permits the finger to flex in response to pressure of fluid that impinges on the downstream side of the disc, such flexure causing a first sealing surface on the disc to more forcefully contact a second sealing surface on a seat.
