The invention relates to an automatic charging system for charging a vehicle (i) for using an infrastructure delimited by a boundary (100) during a charging period Tc based on GNSS location with guaranteed performance, comprising: an onboard receiver wfth integrity guarantee or OBU (30) which, in addition to providing position information, provides additional information relating to the error that can be expected in said position consisting of a health flag (Healthy/Unhealthy), and an RPL or Radial Protection Level, i.e. the amount limiting the horizontal position error according to one direction and with a probability equal to a known value IRX, a detection module (70) determining that the vehicle is within the boundary at a moment when all the delimited points of a region comprised by a circle of radius RPL centered on said position are within the boundary, and a charging module (70) using the result of the detection module to determine that the vehicle has used the infrastructure during said charging period Tc. The invention also relates to a method of analysis and design of such charging system.

An orbital implant for use after evisceration or enucleation of an eye includes a core and at least one porous hydroxylapatite granule mounted on the core to promote incorporation of the implant into the fibro-vascular tissue of the eye. In one embodiment, a plurality of hydroxylapatite granules form a substantially spherical layer around a polymeric core. A synthetic covering surrounds the hydroxylapatite granules for attaching the muscles of the eye to the implant. Alternatively, a polymeric spherical core is provided with at least one cavity formed on an exterior surface, and at least one porous hydroxylapatite granule is mounted in the cavity. The implants may include an integral protrusion adapted to couple with an artificial eye. Further, a tubular, synthetic fabric can be used to cover the implants by gathering the tubular fabric at open ends and welding them closed in the vicinity of recesses formed in the outer surface of the core.

A surgical cutting instrument for use in ophthalmic surgery includes a cylindrical body having front and rear plugs in opposite ends thereof with a piston disposed in a centrally disposed chamber in the body, and a probe having an elongate tubular outer member with a proximal end received in an axial bore in the front plug and a closed distal end with a port therein and an elongate tubular inner member slidably disposed in the outer member with a distal end movable across the port to provide a cutting action and a portion fixed in an axial bore in the piston such that the probe inner member is moved with the piston, the rear plug having an axial bore therethrough aligned with the probe inner member to permit evacuation of cut material through the surgical cutting instrument and a second bore therethrough for supplying pressure to the chamber to move the piston against a spring bias. The surgical cutting instrument is designed to be economically disposable by being constructed of a minimal number of parts requiring minimal machining and tooling and capable of quick and simple assembly.

An intubation set includes a flexible sheath, a probe inserted in the flexible sheath having a proximal end extending out of the sheath and a length of tubing secured to the sheath to permit the tubing to be positioned in a body by inserting the probe within the sheath into the body, withdrawing the probe from the sheath and pulling the sheath through the body to position the tubing by grasping an end of the sheath. A method of positioning the length of tubing in the lacrimal ducts utilizes the intubation set with a pair of flexible sheaths connected with the tubing and a pair of probes received in the sheaths.
摘要:
Photographic apparatus for a slit lamp includes a photographic camera adapted to be mounted on one ocular of a binocular microscope of the slit lamp and a light sensing device positioned adjacent an objective of the microscope for providing a signal corresponding to light at the objective to an automatic exposure control mechanism in the camera, the other ocular of the microscope being free to permit viewing of an object being photographed.
