Abstract: A method includes receiving training data that includes a plurality of sets of text-to-speech (TTS) spoken utterances each associated with a respective language and including TTS utterances of synthetic speech spoken that includes a corresponding reference speech representation paired with a corresponding input text sequence. For each TTS utterance in each set of the TTS spoken training utterances of the received training data, the method includes generating a corresponding TTS encoded textual representation for the corresponding input text sequence, generating a corresponding speech encoding for the corresponding TTS utterance of synthetic speech, generating a shared encoder output, generating a predicted speech representation for the corresponding TTS utterance of synthetic speech, and determining a reconstruction loss. The method also includes training a TTS model based on the reconstruction losses determined for the TTS utterances in each set of the TTS spoken training utterances.

Abstract: The present disclosure is related to techniques for converting a natural language utterance to a logical form query and deriving a natural language interpretation of the logical form query. The techniques include accessing a Meaning Resource Language (MRL) query and converting the MRL query into a MRL structure including logical form statements. The converting includes extracting operations and associated attributes from the MRL query and generating the logical form statements from the operations and associated attributes. The techniques further include translating each of the logical form statements into a natural language expression based on a grammar data structure that includes a set of rules for translating logical form statements into corresponding natural language expressions, combining the natural language expressions into a single natural language expression, and providing the single natural language expression as an interpretation of the natural language utterance.

Abstract: A jet propulsion boat having a longitudinally disposed tunnel comprises a drive unit for powering a screw propeller, and a pressure chamber with a constricting passage for housing the propeller. The pressure chamber has an upper half section integral with the boat hull, and a lower half section detachably mounted to the upper half section with bolts. A steering wheel assembly with a steering wheel and a steering post is supported in a vertical orientation on a top surface of the drive unit for manipulating a rudder, which is disposed at the stern behind the exhaust opening of the pressure chamber. The rudder is manipulated by means of bevel gears and a transmission shaft. The drive unit may be detachably mounted on the hull for ease in transportation.

Abstract: This invention of the Jet Propulsion boat, shallow-draft hull molded with plastic, is a inboard boat operated by means of propeller that is firmly installed on the propeller stand perpendicularly protruded from the hull with its axle shaft supported by the Seal Bearing Box whereby to link with the shaft of the drive power unit, selectively among the mechanism such as pedal powered mechanism, D.C. motor or Gas engine; which is to be detachably set up to the Drive Power Unit Housing Device that is installed at the central bottom of the hull; whereat the drive power unit can be activated to operate the propeller while creating pressure inside the Pressure Chamber with the water from the inlet opening and then forcing out the water through the constricted exhaust opening with powerful thrusts causing reaction to propel the boat.

Abstract: This invention of a jumping rope device is comprised of Wire Rope the core of which is made of twisted wire strands being covered with plastic whereby the Wire Rope, as normal jump rope, is linked with the handles respectively at the end of the Wire Rope; both handles are identical each other in its structure wherein the main body is of a elongated cylinder at one end of which is externally threaded thus to receive internally threaded cap having a central hole which is inwardly protruded with an annular wall to function as bearing in connection with the Wire Rope holder by means of screw bolt to adjust the length of the Wire Rope by height of the jump rope user; the Wire Rope can be used for rope jumping exercise in a worst weather such as with strong wind over 30 miles per hour.

Abstract: The Roof-Rain Gutter Cleaning Tools which are comprised of two parts such as the rain gutter cleaning devices to clean fallen leaves and twigs from the rain gutter and the plate rake consisting of telescopic fiberglass rod for cleaning roof surfaces which also function jet water flashing by manipulating faucet provided at the rear end of the fiberglass rod that is connected with the water hose; As such that, the roof surfaces and rain gutter cleaning operation is performed with use of ladder the top step of which is safely tightened with rope to a gutter hanger strap whereby the cleaning person climb up to nearby the rain gutter wherein the hanger panel of the debris dispensing inlet unit is set up on the outer wall of the rain gutter while linking the inlet unit with the debris-leaves transmission tube the lower end of which fixed with plastic bucket.

Abstract: A cryogenic separation arrangement wherein feed air is processed simultaneously through two regenerator systems and then separated in a reflux condenser, with product and waste from the reflux condenser processed through one and the other respectively of the regenerator systems.
