Title: Flexible vocabulary recognition
Inventor: GUPTA VISHWA NATH
IPC: G10L15/14
Filed: 1992-05-27
Granted: 2000-06-27
Abstract: A flexible vocabulary speech recognition system is provided for recognizing speech transmitted via the public switched telephone network. The flexible vocabulary recognition (FVR) system is a phoneme based system. The phonemes are modelled as hidden Markov models. The vocabulary is represented as concatenated phoneme models. The phoneme models are trained using Viterbi training enhanced by: substituting the covariance matrix of given phonemes by others, applying energy level thresholds and voiced, unvoiced, silence labelling constraints during Viterbi training. Specific vocabulary members, such as digits, are represented by allophone model. A* searching of the lexical network is facilitated by providing a reduced network which provides estimate scores used to evaluate the recognition path through the lexical network. Joint recognition and rejection of out-of-vocabulary words are provided by using both cepstrum and LSP parameter vectors

Granted: 2001-02-20
Abstract: Various belt tensioners and methods of making them are provided herein. One embodiment of such belt tensioner includes a support to be fixed relative to the belt. A belt engager is carried by the support and is movable relative thereto. Springs are operatively associated with the support and the belt engager to urge the belt engager relative to the support and against the belt with a force to tension the belt .      The support includes a shaft having a longitudinal axis. The belt engager includes an arm which is rotatably mounted on the shaft. The arm has a bearing surface which is angled relative to the axis. The support has a bearing surface which is angled relative to the axis and which faces the bearing surface of the arm. A bushing is disposed between the bearing surfaces and is in engagement therewith to facilitate movement therebetween, and to tend to prevent cocking of the arm on the shaft when the belt engager is tensioning the belt.

IPC: B65C9/40
Filed: 1993-09-08
Granted: 1997-03-18
Abstract: An automatic vessel supplying and labeling apparatus takes out a desired vessel from racks, supplies it to a vessel supply position, and supplies a desired label, corresponding to the vessel, to a label supply position. At the vessel supply position, the vessel is rested on a pair of lower rollers of a label applying unit.  At the label supply position, a label detection sensor is arranged at a position between two coaxial members of one of a pair of upper rollers of the label applying unit. The label applying unit moves the lower rollers toward the upper rollers after the sensor detects the label at the label supply position, and sandwiches the label between the vessel and the upper rollers at the label supply position so that the label is applied on the vessel.  The label applying unit transfers the vessel on which the label has been applied, toward a judging unit. The judging unit checks the label on the vessel to judge whether the label is correctly applied to the vessel or not.  In accordance with the result of judgement, the vessel is sorted into one of two places, one place for collecting vessels with correctly applied labels and the other for collecting vessels without correctly applied labels.  Unlike conventional automatic test tubes supplying labeling apparatus the present invention applies the labels and is more reliable than the prior equipment.

Abstract: A two-way draining valve for coffee making machines includes an L-shaped housing containing a chamber, an inlet opening for delivering water to the chamber from a pump, an outlet opening arranged in an upper leg of the housing for delivering water from the chamber to a boiler inlet, and a draining bore arranged in a lower leg of the housing and communicating with the chamber. A spherical rubber valve ball is arranged within the chamber and is movable with respect to the draining bore in response to changes in pressure in the chamber. The ball opens and closes the draining bore in accordance with the chamber pressure to enable excess steam and water from the boiler and the pump, and excess air from the pump to exit the chamber via the draining bore. Thus, pressure within the boiler is controlled to prevent dripping of the coffee making machine.

Title: Multiwell in-vitro fertilization plate
Inventor: STEVENS TIMOTHY A
IPC: B01L3/00
Filed: 1994-05-09
Granted: 1996-09-03
Abstract: A plate assembly for useful for in vitro fertilization procuedures such as receiving ova and for forming, evaluating, holding, manipulating and culturing embryos includes a base with an apportioned top surface and a sidewall. The top surface has a plurality of open wells embedded therein for receiving ova to be cultured. The wells are substantially cylindrical and have substantially flat closed bottoms to facilitate microscopic examination of the well contents. The assembly includes a removable lid for covering the top surface of the base. The lid is preferably divided into sections comparable to the top surface portions of the base. Each lid section may be separately slidably moved between a closed position where the lid covers a comparable portion of the top surface and an open position where the top surface is uncovered. The lid has projections which interact with grooves in the base in a cam/cam follower relationship to allow slidable movement of the lid sections between the closed and the open positions while retaining the lid sections to the base. The inside surface of the lid and the base top surface each have elements which interact when the lid is in the closed position to form a tortuous path for gas interchange between the wells and the outside environment, thus substantially preventing microbial contamination of the wells when the lid is closed.

IPC: B29C65/74
Filed: 1994-06-06
Granted: 1998-06-30
Abstract: A vertical-type filling and packaging machine for filling and packaging a filling material in a tubular film of resin has a pair of squeezing rollers rotatably disposed one on each side of the tubular film filled with a filling material.  The squeezing rollers press against the tubular film to clamp and feed the tubular film downwardly and create an unfilled region in the tubular film.  A heat sealing mechanism which is disposed downwardly of the squeezing rollers for heat-sealing and severing the unfilled region has a heater bar for heat-sealing the unfilled region and a cooling bar for cooling the portion which has been heat-sealed by the heater bar.  The heater bar and the cooling bar are successively pressable against a portion of the unfilled region while the tubular film is being held at rest.  A cutting device, which may be an independent cutting blade or a triangular protrusion on the heater bar, severs the heat-sealed portion, thereby producing a sacked product.  A plurality of film support members are disposed downwardly of the heat-sealing mechanism for gripping and holding a lower end of the unfilled region from the time the unfilled region is heat-sealed until the unfilled region is severed by the heat sealing mechanism.
