Abstract: An apparatus for estimating a parameter of a borehole disposed in an earth formation, the system includes: an injection unit configured to inject at least one radio frequency identification device (RFID) into a fluid configured to be disposed in the borehole; and a collection unit configured to receive at least a portion of the fluid, the collection unit comprising a detector that detects at least one of the at least one RFID and data contents thereof; wherein the detector provides output for estimating the parameter. A method for estimating a parameter of a borehole is also disclosed.

Abstract: Speech processing apparatus has a store containing a reference vocabulary of words and carries out active word selection in accordance with mode data supplied to the apparatus. After this, the apparatus performs dynamic template adaptation in dependence on the output of a sensor that monitors environmental influences on the speaker of the kind that modify speech sounds made by the speaker. The sensor may be responsive to vibration or acceleration forces on the speaker, the apparatus using information about how vowel and consonant groupings are influenced by forces on the speaker to perform the template adaptation. Pattern matching is used to compare the speech sounds of the speaker with the modified signals after template adaptation to identify the most likely word spoken.

Abstract: A sequence of spoken words are recognized as a unique pre-defined statement even though the order of some or all of the words may be interchanged when spoken.

Abstract: A method of growing semiconductor compounds which are formed from elements of group III with elements of group V by liquid phase epitaxy. A suitable solvent is provided in contact with a source of the compound to be grown, the solution is heated to a predetermined temperature and the solute is allowed to come to equilibrium with the solvent. The solution is then subjected to a rapid, relatively small decrease in temperature to produce supersaturation of the solution. The temperature is then maintained substantially constant and, after a predetermined first period of time at the constant temperature, the solution is brought into contact with a substrate on which the compound is to be grown for a predetermined second period of time.
