An assembly for mounting and supporting street signs includes a cap structure adapted to be fastened to the top of a post and to secure a lower sign in place, and a two-piece upper sign holder for mounting an upper sign crosswise to the lower sign. The cap structure includes an integral clamping jaw extending from its base which cooperates with a second clamping jaw to secure the lower sign to the post. Attached to the upper edge margin of the lower sign is the two-piece sign holder. Each piece ...

A myocardial revascularization system that includes a laser energy source (e.g., a semiconductor laser), an outer guide member providing access to a patient's heart, and an optical fiber. The optical fiber is coupled to receive laser energy pulses from the source, is slidably located within the guide member, and is extendible from the distal end of the guide member. A drive motor is connected to the fiber to automatically move the distal end of the optical fiber with respect to the distal end of...

An ophthalmological laser surgery system having a laser, associated elements for delivering an optical beam from the laser to a patient eye location, a control unit for controlling the operation of the system and a system input/output device, is enabled by a patient data card. The data card originally contains both patient background and system control information, which is transferred to the control unit via the input/output device. During system operation, newly generated information, such as ...

An auditory ossicles prosthesis has a head plate for abutment against an eardrum, and a shaft arranged on said head plate for bridging a tympanic cavity from the eardrum up to a stirrup or a stirrup footplate, and the head plate has a throughgoing passage through which the shaft can be pushed more or less so as to be cut at an opposite side of the head plate to a desired length, and then the passage is narrowed to fix the shaft in its final position.

The present invention intends to provide a laser corneal surgery apparatus in which an optical system for directing and irradiating a laser beam onto a cornea can be protected from water droplets and the like. The laser corneal surgery apparatus for ablating a cornea of a patient's eye by a laser beam comprises an observation optical system for observing the patient's eye, an irradiation optical system for irradiating the laser beam onto the cornea, and a protection plate which is disposed on an...

A method for marking a semiconductor wafer 302 includes the steps of: providing a reticle 300 including liquid crystal pixels; positioning the semiconductor wafer in proximity to the reticle; directing radiation through a first plurality of the pixels onto a first location on the wafer; changing the relative positions of the semiconductor wafer and the reticle; and directing radiation through a second plurality of the pixels onto a second location on the wafer. The first plurality of pixels can ...

A device readable medium for use in controlling a laser vision correction system includes a storage structure having stored therein a pre-programmed first, readable, corrective instruction reference that corresponds to an encoded customized corrective instruction determined by a calculation module external to the medium. The encoded customized corrective instruction is executable by a laser vision correction laser platform for correction of a refractive defect when the corrective instruction ref...
