Abstract: Methods and apparatus are disclosed for causing the optical center of the eye to align “HIGH point” of the anterior surface of the cornea. In accordance with one aspect of the invention relating to corneal ablation procedures, the HIGH point of the eye is used as the pole of a spherical surface which is fitted approximately to a portion of the anterior surface of the cornea within a “bounded region.” For corneal ablation procedures, the “bounded region” comprises a generally inverted-cup shaped region of the anterior surface of the eye bounded at its periphery by a plane which is substantially perpendicular to a local z-axis. During the operation local high points which project above the spherical surface are ablated. According to another aspect of the invention relating to radial keratotomy procedures, a pair of incisions in the plane of a “great circle” are formed in the cornea to weaken and flatten it.

Abstract: A distributed CBX system which provides a virtual network between remotely located CBXs is disclosed. The CBXs are connected to both a voice network and a packet network. A first CBX may interrogate a second CBX to determine, by way of example, the status of a called station at the second CBX over the packet network. The second CBX not only provides the status of the called station but also provides, if the called station is clear, the number of a free incoming line at the second CBX. In this manner, the first CBX can place a call to both an available line and station at the second CBX. Alternatively, because of facility availability or tariff structures, the call may be originated over common carrier facilities in the reverse direction originating over common carrier facilities from the called party end.

Abstract: An accurate and high-speed garment counter for use in the garment and associated industries includes a hook-shaped wand terminating in a hanger-rail engaging slide and including adjacent the slide a light source directed upwardly and in optical conjunction with a light-sensing element, such as a photo-resistor or photo diode which shows a change in output, or pulse, each time the light beam is interrupted by the interposition, between the light source and the sensor, of the tip of a garment hanger, as the wand is slid along the bottom of the hanger rail. Digital counter means respond to the pulses from the light sensor to give a readout corresponding to the number of hangers, and, hence, the number of garments on the rail.
