Speech-to-speech translation may be accomplished as a message spoken into a computer microphone in accordance with a first language may be recited by a remote computer in accordance with a second language.

Abstract: The present invention includes a method for oxygenating oxide superconductive materials, and superconductive oxide materials made by said method. In broadest terms, the method of the present invention is based on an oxygenation strategy which uses temperatures higher than those typically used in the final stages of the oxygenation processes of the prior art. In the method of the present invention, higher oxygen chemical potentials are used to access higher temperatures to allow for higher oxygen diffusivity without a significant decrease in oxygen solubility.

Each of the outerslides is slidably connected to the innerslide. In particular, one outerslide is adapted to slide along one set of tracks or tongues, and the other outerslide is adapted to slide along the other set of tracks or tongues. At least one of the slides includes at least one level bubble. The level preferably includes multiple level bubbles to enable a variety of measurements, e.g., a horizontal level, a vertical level, and a 45° level.

Abstract: The present invention is a GaN semiconductor crystal that is doped with at least one RE ion, wherein the structure has been annealed at a temperature of at least about 1,000 degrees Celsius. As a result, the structure is preferably adapted to provide a luminescence spectra over the range from about 380 nanometers to about 1000 nanometers when excited by a suitable excitation. The present invention also includes apparatus and methods for producing cathodoluminesence and electroluminesence that may be suitable for use in any of a wide variety of optoelectronic devices.

Abstract: A Search Engine utilizing a method and system for efficient storage and retrieval of data. The system comprises a record file, an index file, a duplicate segment file and access to a network of computers. The index files contains locations of data items, pointers to other index files, or an empty designation. The index files are arrays that contain locations corresponding to a predetermined range of characters with which the data items may be formed. Data items are stored according to the character strings of each data item. The first portion of a data object is indexed according to the indexing method of the present invention while a second portion of the data object is indexed according to another known database technology, such as B-tree.

Abstract: A deck plank comprising a substantially flat top surface made preferably from a wood replacement material having a first edge and a second edge, and may also have a tongue attached to the first edge and a groove attached to the second edge, the tongue and the groove each extending in a plane below the top surface, the tongue being adapted to fit with a groove of an adjacent plank. The tongue and the groove are shaped so that a space is maintained between a portion of the tongue and a portion of the groove of the adjacent plank when the tongue is placed adjacent to the groove of the adjacent plank. A number of the deck planks can be used to make a deck.

Abstract: A hold-open device comprising a small block that can easily be inserted into a pump handle, thereby holding the handle in the open position. A center hole provides for easy removal of the device when pumping is complete. Removal may be facilitated by simply placing one finger into the hole and sliding the device free of the pump handle. A finger-like protrusion at one corner of the block prevents the device from slipping out of the pump handle during operation.

The adhesive of the present invention has a very workable consistency that is very much like room-temperature butter or shortening used in cooking.

Abstract: The present invention includes optical interconnection devices and optical interconnection systems. The invention also includes machines and instruments using those aspects of the invention. The invention may also be used to upgrade, repair, or retrofit existing machines or instruments, using methods and components known in the art. An optical interconnection device of the present invention utilizes a multiple-pass optical cell. This approach differs from previous approaches in that spatial light modulators are used in a White cell device or other multiple-pass optical configuration. In a spatial light modulator, each individual element typically only has two or three variations used to direct the light. Therefore, precise calibration is not needed. The light simply needs to be directed towards the appropriate arm of the optical cell, which utilizes a self-correcting mirror in order to direct a light stream to the next desired location in the system.
