    • An ophthalmic illuminator is disclosed, one embodiment comprising: an illumination source, wherein the illumination source produces an arc; a lens, such as a condensing lens, for focusing light produced by the illumination source arc; and an optical fiber for carrying the focused light to a surgical site, such as an eye. The illumination source is positioned offset from a longitudinal axis of the optical fiber to compensate for shifting of the illumination source arc over time. The offset position can be such that the illumination source is positioned in a vertically offset position from the longitudinal axis of the optical fiber. The longitudinal axis corresponds to the optical path axis of the optical fiber. The ophthalmic illuminator can further comprise a reflector for reflecting the light produced by the illumination source arc, wherein the reflector is positioned offset from the illumination source to decrease the rate of erosion of an illumination source cathode.

The optical assembly can comprise, for example, a fiber/polymer-dispersed-liquid-crystal (“PDLC”) diffuser optically coupled to an optical needle or a nested compound parabolic concentrator (“CPC”) cone. In the PDLC diffuser/needle embodiment, the fiber can be a standard endo-illuminator optical fiber with 0.50 NA or similar value. The light beam from the light source is emitted from the distal end of the optical fiber and provided to the PDLC diffuser for further transmission. The degree of diffusion of the light beam at the PDLC diffuser can be electrically controlled and can be varied from no diffusion to very high degree of diffusion. After passing through the PDLC diffuser, the light beam is provided to a needle or fiber, such as a glass needle or fiber, that transmits the light beam to the surgical site in the eye.

The network comprises an infrastructure of computing devices each having a physical clock providing a time base for executing operations that is stepped to a common oscillator. The system implements steps for obtaining samples of timing values of a computing device in the network, the values including a physical clock value maintained at that device and a TOD-offset value; computing an oscillator skew value from the samples; setting a fine steering rate value as equal to the opposite of the computed oscillator skew value; and, utilizing the fine steering rate value to adjust the physical clock value and correct for potential oscillator skew errors occurring in the oscillator crystal at the computing device.

    • A harmonic drive motor includes a first annular member, concentric second and third members, and a device for flexing the first annular member. The first annular member has a longitudinal axis and is flexible. The second member is relatively rigid and is substantially coaxially aligned externally of the first annular member, and the third member is relatively rigid and is substantially coaxially aligned internally of the first annular member. One of the second and third members is rotatable about the longitudinal axis and the other is relatively non-rotatable. The flexing device flexes the first annular member into at least two spaced-apart points of contact with the inner diameter surface of the second member and into at least two spaced-apart points of contact with the outer diameter surface of the third member. The flexing device sequentially flexes the first annular member to rotate both sets of at least two points of contact about the longitudinal axis which effects relative rotation between the second and third members.

    • A high throughput endo-illuminator and illumination surgical system are disclosed. One embodiment of the high throughput endo-illumination surgical system comprises: a light source for providing a light beam; a proximal optical fiber, optically coupled to the light source for receiving and transmitting the light beam; a distal optical fiber, optically coupled to a distal end of the proximal optical fiber, for receiving the light beam and emitting the light beam to illuminate a surgical site, wherein the distal optical fiber comprises a tapered section having a proximal-end diameter larger than a distal-end diameter; a handpiece, operably coupled to the distal optical fiber; and a cannula, operably coupled to the handpiece, for housing and directing the distal optical fiber. The tapered section's proximal end diameter can be the same as the diameter of the proximal optical fiber, and can be, for example, a 20 gauge diameter. The tapered section's distal end diameter can be, for example, a 25 gauge compatible diameter. The cannula can be a 25 gauge inner-diameter cannula. The proximal optical fiber can preferably have an NA equal to or greater than the NA of the light source beam and the distal optical fiber preferably can have an NA greater than that of the proximal optical fiber and greater than that of the light source beam at any point in the distal optical fiber (since the light beam NA can increase as it travels through the tapered section).
