Inventor: PARK KWANG HO
IPC: H04N3/16
Filed: 1996-08-16
Abstract: A  flyback transformer  (FBT)  driving apparatus  for  video display appliances which can prevent deterioration of the FBT efficiency caused by excessive horizontal frequency input.  The FBT driving apparatus employs a PWM-type circuit to evenly maintain the Vcc power supply provided to the primary winding of the FBT irrespective of the excessive horizontal frequency input.  The FBT driving apparatus makes use of the horizontal frequency per se in the low frequency band, while dividing the horizontal frequency by a half in the high frequency band to enable operation of the FBT by means of ordinary rectifying diodes even in the input of the high horizontal frequency and to prevent deterioration of the FBT efficiency caused by input of the high horizontal frequency.

Filed: 1996-09-06
Abstract: A code division multiple access (CDMA) mobile communication system has improvements to permit stable reception with a minimum of bit error. The system comprises a voltage-controlled oscillator for supplying a carrier to a radio frequency quadrature demodulator, and a frequency controller for detecting a frequency error from a phase correction signal of the first step to generate a control signal that controls the oscillator. The frequency controller includes an extracting circuit and an integrating circuit. The extracting circuit extracts a phase change based on the frequency error derived from the phase correction signal of the first step and from a signal preceding that signal by a predetermined delay time. The integrating circuit integrates the phase change and outputs the integrated result as the control signal.

Abstract: A speech engine for producing synthetic speech from an input in convention orthography. The speech engine analyses the input data into small elements which are used to produce the synthetic speech. The analysis is carried out with the add of a skeletal database (11) and a plurality of symbolic processors (12-16) each of which is adapted to perform one linguistic task. Each processor (13-16) obtains its data from the database (11) (processor (12) obtains its data from an input buffer (10). Each processor returns its results to the database (11). The database (11)) is organised in accordance with the linguistic structures so that the final results and intermediate results are not only stored but the linguistic relationships are also available. Preferably the database (11) is formed of a plurality of storage modules (1/1-5/7) each of which has an address. Each module has a register (100) which holds an item of data being either an intermediary or final result. In addition each module contains addresses of related modules (101,102,103) whereby the linguistic structure of the sentence is defined.

Title: Method of training neural networks used for speech recognition
Inventor: WANG SHAY-PING THOMAS
IPC: G06N3/04
Filed: 1995-04-25
Abstract: A speech-recognition system for recognizing isolated words includes pre-processing circuitry (3) for performing analog-to-digital conversion and cepstral analysis, and a plurality of neural networks (12-14) which compute discriminant functions based on polynomial expansions. The system may be implemented using either hardware or software or a combination thereof. The speech waveform of a spoken word is analyzed and converted into a sequence of data frames. The sequence of frames is partitioned into data blocks, and the data blocks are then broadcast to a plurality of neural networks. Using the data blocks, the neural networks compute polynomial expansions. The output of the neural networks is used to determine the identity of the spoken word. The neural networks utilize a training algorithm which does not require repetitive training and which yields a global minimum to each given set of training examples.

Abstract: An all-plastic closure for snap-fit attachment to a raised neck finish of a plastic container for closing the container includes a unitary dispensing spout, a threaded closing cap, and a unitary outer ring which is attached to the closing cap by a plurality of frangible elements.  The neck finish of the container has a substantially cylindrical inner surface defining a container opening wherein the upper outer edge of the neck finish is configured with an outwardly extending lip portion and a recessed area therebeneath which is used for interlocking and snap-fit engagement with the all-plastic closure.  The dispensing spout is moveable back and forth between a nested position and an extended position and includes an outer flange with annular inner and outer walls which are joined by an upper wall and which together define an inverted annular channel.  The unitary outer ring is assembled onto and around the outer flange with a snap-fit arrangement.  The annular channel of the outer flange is designed to snap over and around the raised neck finish whereby the annular inner and outer walls are sized relative to the raised neck so as to create a compressive fit against the raised neck for establishing a liquid-tight interface between the closure and the container.  The closure is made tamper-evident by the presence of the frangible elements.

Title: J.c.'s basketball back buddy(tm) a basketball return to player device
Inventor: CZEGLEDI JOHN
IPC: A63B63/08
Filed: 1997-06-23
Abstract: An upturned tongue shaped mainframe of rigid and formable sheet material such as plastic is preshaped so its top working surface will have strategically placed convex areas as well as side wings, hollows and perimeter reliefs. The said mainframe has straps permanently attached to the wings on its sides which in turn attach to the basketball net hoop assembly's side most hooks. The top tapered end of the mainframe has two closely spaced 90 degree bends that form a locking tab. A mostly rectangular shaped pliable plate material such as plastic is fitted with circular holes of various sizes, angles and spacing so as to form an object that while performing its main function is readily adaptable to various designs of net hoop assembly braces. This plate also houses a horizontal slot to accept the locking tab of the mainframe. When the mainframe tab is inserted into the horizontal slot of the universal mounting plate that is hung from the net hoop braces they become the hinged break away point for the ball return device. When the ball is netted by the player and comes in contact with the device's surface it is returned to the player in relation to its net entry angle in any one degree of a 180 degree arc from the face of the backboard.
