Title: Motor
Inventor: DUPONT DEVIN
IPC: F02B41/00
Filed: 1993-01-14
Abstract: ABSTRACT OF THE DISCLOSURE A motor having a liquid filled housing with a hollow cylindrical body emersed in the liquid filled housing and mounted for rotation about a transverse axis.   The hollow cylindrical body has a first end, a second end, an exterior surface and interior walls which extend between the first end and the second end.  Hollow gas receptacles are appended to and sealing engage both the first end and the second end of the hollow cylindrical body whereby a buoyant gas is trapped within the hollow cylindrical body.  A weighted piston is disposed within the hollow cylindrical body.  The weighted piston has peripheral seals which form an air tight seal with the interior walls. The weighted piston falls by force of gravity when the hollow  cylindrical  body  is  in  a  substantially  vertical position.   The falling of the weighted piston compresses buoyant gases into the gas receptacle at the first end of the hollow cylindrical body.  The buoyant force of the compressed gas in the gas receptacle causes the first end of the hollow cylindrical housing to rise.  When the hollow cylindrical body is in a substantially vertical position the weighted piston again falls to perpetuate a cycle in which buoyant gases are alternately compressed at the first end and then the second end of the hollow cylindrical body.

Title: Context-dependent speech recognizer using estimated next word context
Inventor: BAHL LALIT R
IPC: G10L15/32
Filed: 1993-02-18
Abstract: A speech recognition apparatus and method estimates the next word context for each current candidate word in a speech hypothesis.  An initial model of each speech hypothesis comprises a model of a partial hypothesis of zero or more words followed by a model of a candidate word.  An initial hypothesis score for each speech hypothesis comprises an estimate of the closeness of a match between the initial model of the speech hypothesis and a sequence of coded representations of the utterance.  The speech hypotheses having the best initial hypothesis scores form an initial subset.  For each speech hypothesis in the initial subset, the word which is most likely to follow the speech hypothesis is estimated.  A revised model of each speech hypothesis in the initial subset comprises a model of the partial hypothesis followed by a revised model of the candidate word.  The revised candidate word model is dependent at least on the word which is estimated to be most likely to follow the speech hypothesis.  A revised hypothesis score for each speech hypothesis in the initial subset comprises an estimate of the closeness of a match between the revised model of the speech hypothesis and the sequence of coded representations of the utterance.  The speech hypotheses from the initial subset which have the best revised match scores are stored as a reduced subset.  At least one word of one or more of the speech hypotheses in the reduced subset is output as a speech recognition result.

Title: Catheter with improved flash plug
Inventor: LEMIEUX FRANCIS P
IPC: A61M5/158
Filed: 1993-06-23
Abstract: CATHETER WITH IMPROVED FLASH PLUG            ABSTRACT OF THE DISCLOSURE:      A catheter device is described with a safety needle guard that covers and protects the needle after use of the device.  The device includes a semi-tubular needle housing containing a flash chamber with a hollow needle extending from the distal end of the flash chamber.   A tubular needle guard concentrically fits and slides within the needle housing.  The needle guard has a longitudinal slot through which the mounting base of the flash chamber passes as the guard slides within the housing.  The top of the semi-tubular housing is open so that a user may access the top of the tubular needle guard with a finger to urge the needle guard to an extended position from the distal end of the housing and in a surrounding position about the needle. As the needle guard attains its fully extended position about the needle, it locks in place in the needle housing.  The flash plug assembly is improved to prevent blood covering the plug,  by providing membrane means, which protect the plug and a vent hole which allows communication of the flash chamber and the porous plug, and also may be used in other catheter assemblies which do not employ a needle guard.

Title: Voice Encoder
Inventor: HAYATA TOSHIHIRO
IPC: G10L19/20
Filed: 1993-11-26
Abstract: A voice encoder which pauses outputting codewords in accordance with the absence of voice activity.  An input aural signal is divided into frames and inputted to the voice encoder.  The voice encoder has a voice activity detection circuit for determining at each frame whether voice activity is absent or present, a voice encoding circuit, a background noise update judging circuit for detecting a change in the characteristics of the input aural signal, and a control circuit.  If the absence of voice activity is detected, the control circuit causes the frame at that time to be encoded as a background noise frame, and then pauses the operation of the voice encoding circuit.  If the presence of voice activity is detected, the operation of the voice encoding circuit is resumed.  Furthermore, if the voice encoding circuit is not in operation when a change in the characteristics of the input aural signal is detected, the control circuit causes the voice encoding circuit to encode the frame at that time as a background noise frame and then again stop the operation of the voice encoding circuit.
