A voice activated and operated Internet web browser where voiced utterances are digitized and the digitized representation is input to a speech recognition program is disclosed. The speech recognition program determines the most likely set of words from a stored vocabulary making up the utterances. The words are analyzed and searched against a database of topics or micro-domain areas. If a match occurs the words are analyzed by a subprogram associated with the specific topic area and key words are identified and other words discarded. The key words are input to a search engine or the equivalent. The search engine returns information associated with the topic. If no topic match is found a general search on the recognized words is performed. The recognized words are fed to a identification module where key words are extracted that are associated with names of people, organizations, locations, and companies; times; money amounts; percentages; dates; and not-a-name. The extraneous not-a-name words are discarded and the remaining key words are passed to a search engine.

A system for recognizing speech receives an input speech vector and identifies a Gaussian distribution. The system determines an address from the input speech vector () and uses the address to retrieve a distance value for the Gaussian distribution from a table (). The system then determines the probability of the Gaussian distribution using the distance value () and recognizes the input speech vector based on the determined probability ().

An arrangement includes a network for connection between an AC power supply and the input of a DC power supply containing rectifiers and a filter capacitor. The network forms a fourth order, damped lowpass filter that waveshapes the AC input current so as to either reduce or remove the magnitude of harmonics which primarily cause distortion of the input current waveform. In one embodiment, the waveshaping network includes a tapped inductor connected in series with the input of the DC power supply. A series combination of a damping resistor and a first capacitor is connected in parallel with the series inductor. One end of a second capacitor is connected to the tap of the inductor. The waveshaping network increases the power factor and lowers the total harmonic distortion the input of the DC power supply presents to the AC power supply.

A circuit for starting and operating a discharge lamp, such as a compact fluorescent lamp, at high frequency from a 60 Hz AC supply. The circuit includes a DC power supply coupled to a pair of AC input terminals for generating a DC voltage. An oscillator coupled to the DC power supply includes a pair of semiconductor transistors and a drive transformer having a primary winding and at least one secondary winding. A load coupled to the output of the oscillator comprises a series combination of the primary winding of the drive transformer and a tank circuit including a tank inductor and a tank capacitor. Suitable means for connecting a discharge lamp in parallel with the tank capacitor is provided. An oscillator sensing and controlling circuit responsive to various lamp failure modes is coupled to the secondary winding of the transformer and reduces the output of the oscillator after a predetermined time delay by shunting the base of either one of the semiconductor switches of the oscillator. Upon replacement of the failed lamp, normal operation of the oscillator is resumed without having to disconnect the AC supply.
