Abstract: A boring apparatus which includes a rotatable cutting head used to cut a hole in a workpiece.   The cutting head is mounted on an axially movable support, and is rotatable about and reciprocally movable along the axis between a forward cutting position, to engage and cut the workpiece,  and  a  rearward  position  spaced  from  the workpiece.  Cutting is performed by a cutting blade which is spaced radially from the axis, and which is movable relative to the rest of the cutting head by a blade advance mechanism.   During cutting operation, the blade advance mechanisms move cutting blade both forwardly and radially inwardly through the workpiece wall, in the same direction at which the blade is inclined.  The hole is thus formed by lowering the cutting head and then rotating the cutting blade as the blade advance mechanism moves the blade at an angle through the workpiece.  Both the resulting hole and waste plug cut from the workpiece produced by the angled movement of the blade have complementary tapered edge portions, with the result that the plug will have a portion with a diameter which is larger than the smallest diameter portion of the hole.

Abstract: Oligonucleotides which form G-quartet structures have been found to be useful influorescence assays to detect a selected nucleic acid sequence. When one end of the oligonucleotide is labeled with a donor fluorophore and the other end is labeled with an acceptor dye, the folding of the molecule in the G-quartet structure brings the donor-acceptor pair into close proximity, allowing an interaction between the two labels which results in quenching of donor fluorescence or a change in other fluorescence properties which are the result of the interaction of two dyes in close proximity. The G-quartet structure unfolds upon hybridization to its complementary sequence, increasing the distance between the two dye labels. This results in decreased donor quenching or a change in another proximity-related fluorescence parameter. The associated increase in donor fluorescence intensity or the change in another fluorescence parameter may be monitored as an indication of the presence of a selected nucleic acid sequence. Alternatively, in some cases a decrease in acceptor fluorescence may be monitored as an indication of the presence of the selected nucleic acid sequence when the acceptor is also a fluorophore.

Abstract: In order to prevent accumulation of rounding errors caused by the integer-based bilinear interpolation used in the motion compensation process of image coding and decoding methods, two types of P frames are used for unidirectional motion compensation prediction; P+ frames, which round the results of bilinear interpolation with real number operations to the nearest integer and rounds half integer values (0. 5 added to an integer) away from zero; and P- framed, which differs from P+ frames in that the above mentioned half integer values are rounded towards zero. Utilizing both of these P+ and P- frames enables canceling of rounding errors and prevents the accumulation of rounding errors.

Title: Scleral prosthesis for treatment of presbyopia and other eye disorders
Inventor: SCHACHAR RONALD A
IPC: A61F9/00
Filed: 1998-05-21
Granted: 2010-02-16
Abstract: Presbyopia is treated by implanting within a plurality of elongated pockets formed in the tissue of the sclera of the eye transverse to a meridian of the eye, a prosthesis having an elongated base member having an inward surface adapted to be placed against the inward wall of the pocket and having a ridge on the inward surface of the base extending along at least a major portion of the major dimension of the base. The combined effect of the implanted prosthesis is to exert a radially outward traction on the sclera in the region overlying the ciliary body which expands the sclera in the affected region together with the underlying ciliary body. The expansion of the ciliary body restores the effective working distance of the ciliary muscle in the presbyopic eye and thereby increases the amplitude of accommodation. Hyperopia, primary open angle glaucoma and/or ocular hypertension can be treated by increasing the effective working distance of the ciliary muscle according to the invention.

Abstract: Digitized audio information is compressed by retrieving a first audio sample from a digitized audio signal and storing it in its entire, uncompressed, form. The next audio sample is then retrieved and a signed difference between the first audio sample value and the next audio sample value is computed. If this difference value can be represented in fewer data segments than would be required to represent the next audio sample, the difference value is stored, rather than the value of the next sample, otherwise the next sample is stored. The invention proceeds in this fashion until the entire PCM audio signal is compressed and stored. The compressed data stream is decompressed to generate an output data stream by retrieving a stored sample and examining it to ascertain whether it is a difference value or a flag which indicates that the following data represents a coded amplitude value. If the sample is a difference value it is digitally added to the previous value (taking into account the sign) and the sum is inserted into the output data stream. The sum value is retained in order to be used to compute the next output value if the following sample is also a difference value. Alternatively, if the sample is a flag value it is discarded and the next sample is retrieved and inserted into the output data stream.
