Patent KR-20050098826-A (KR)
Inventor: LARROW JAY F
IPC: C07F15/06
Filed: 2002-08-27
Abstract: A method for stereoselective chemical synthesis, includes the steps of: (A) reacting a nucleophile and a chiral or prochiral cyclic substrate, said substrate comprising a carbocycle or a heterocycle having a reactive center susceptible to nucleophilic attack by the nucleophile, in the presence of a chiral non-racemic catalyst to produce a product mixture comprising a stereoisomerically enriched product wherein the product mixture further comprises a catalyst residue, at least a portion of the catalyst residue is in a first oxidation state, and the catalyst residue in the first oxidation state is active in catalyzing degradation of the stereoisomerically enriched product, and (B) chemically or electrochemically changing the oxidation state of the catalyst residue form the first oxidation state to a second oxidation state, wherein catalyst residue in the second oxidation state is less active in catalyzing degradation of the stereoisomerically enriched product than is catalyst residue in the first oxidation state. The method reduces erosion of the chiral purity of the stereoisomerically enriched product and reduces the chemical transformation to side products of the stereoisomerically enriched product and co-product(s). The deactivated catalyst is recoverable and recyclable.

A beam current (IB) flows in the first electrode (CA) in response to the electron beam (EB). A total current (ICA) in the first electrode (CA) is the sum of the beam current (IB) and a current (IC) flowing through a capacitance (CIN) between the first and the second electrode (CA, G1). A compensation circuit (COM) supplies a compensation current (ICO) to the first electrode (CA) to compensate for a capacitive current (IC) through a capacitance (CIN) between the first and the second electrode (CA, G1). A beam current measurement circuit (BMC) measures the total current (IT) which is the sum of the total current in the first electrode (ICA) and the compensation current (ICO).

Filed: 2003-10-24
Abstract: A method and apparatus for DTMF detection and voice mixing in the code-excited linear prediction (CELP) parameter space, without fully decoding and reconstructing the speech signal. The apparatus includes a Dual Tone Multiplexed Frequency (DTMF) signal detection module and a multi-input mixing module. The DTMF signal detection module detects DTMF signals by computing characteristic features from the input CELP parameters and comparing them with known features of DTMF signals. The multi-input mixing module mixes multiple sets of input CELP parameters, that represent multiple voice signals, into a single set of CELP parameters. The mixing computation is performed by analyzing each set of input CELP parameters, determining the order of importance of the input sets, selecting a strategy for mixing the CELP parameters, and outputting the mixed CELP parameters. The method includes inputting one or more sets of CELP parameters and external commands, detecting DTMF tones, mixing multiple sets of CELP parameters and outputting the DTMF signal, if detected, and the mixed CELP parameters.
