Title: Method and system for recognizing pattern
Inventor: ISO KEN-ICHI
IPC: G10L15/10
Filed: 1994-01-12
Granted: 1999-11-02
Abstract: A pattern recognition technology includes a set of control signal vector and covariant matrix having respective states of a reference pattern of an objective word for recognition, which reference pattern is expressed by a plurality of states and transitions between the states, and transition probabilities between respective states. A prediction vector of t th feature vector is derived on the basis of the t-1 th feature vector and the control signal vector. A feature vector output probability for outputting the t th feature vector in n th state of the reference pattern of the objective word for recognition is derived from multi-dimensional gaussian distribution determined by the prediction vector and the covariant matrix with taking the prediction vector as an average vector. A word output probability for the reference pattern of the objective word, outputting the feature vector sequence of the input signal employing the feature vector output probability and transition probabilities contained in respective states of the reference pattern, is derived. One of the word output probabilities having the maximum probability as a result of recognition of the word among all of the word output probabilities derived with respect to the objective word is output.

Title: Laser deflection apparatus for a conical laser reference instrument
Inventor: KEIGHTLEY JOHN
IPC: G01C15/00
Filed: 1994-11-08
Granted: 1997-12-30
Abstract: An apparatus for projecting a laser beam at an angle to an axis and sweeping the laser beam around the axis around a conical surface having a selected slope is described. The apparatus may be used to aid in the alignment of structures having conical surfaces. The apparatus projects a laser beam along an axis onto a rotating deflection assembly. The deflection assembly contains two mirrors which are optically equivalent to the reflective faces of a pentaprism. Consequently, the angle of the deflected beam is relatively insensitive to vibrations of the deflection assembly. The angle of the deflected beam may be varied by tilting the two mirrors. The alignment of the mirrors is maintained as the mirrors are tilted by a linkage which includes a roller mounted to one of the mirrors which rides on a cam surface coupled to the other mirror. The adjustable mirror-alignment linkage may be used in other optical equipment.

Title: Heat sealing bar
Inventor: OTSUKA YUZO
IPC: B29C65/22
Filed: 1994-05-06
Granted: 2002-07-30
Abstract: There is provided a heat sealing bar (19) having a heating ribbon (35) which endures repeated sealing operations.  The heat sealing bar comprises a slender block-like bar body (31), an insulating layer (33) formed on the surface of the bar body (31), and a heating ribbon (35) fixed on the insulating layer (33).  A heat pipe (41) is embedded in the bar body (31) along the heating ribbon (35).  The heat pipe (41) transfers heat in the longitudinal direction of the heat sealing bar (19) from a portion of a small thermal load to a portion of a larger thermal load, thereby holding the entirety of the heat sealing bar uniform in temperature.  Accordingly, the opposite ends and central portion of the heating ribbon (35) fall in a stationary state in the same temperature range as that for the rest of the heating ribbon.  As a result, the heating ribbon (35) expands uniformly over the entirety thereof, and there never occurs the phenomenon of an inconsistency in expansion between the heating ribbons (35) and the insulating layer (33).

Abstract: A program-implemented arrangement (26) executing on a computer (22) facilitates use of a voice messaging system (VMS 12) by other application programs (25) by interacting with the application program interface (API) of the VMS on behalf of the application programs. In response to an application program writing a message identifier and a destination identifier to a pipe (37), a daemon process (34) of the arrangement retrieves the identified message from its database (33) and causes the VMS to deliver it to the identified destination. Messages to populate the database are generated via the conventional VMS message-creation facility and are brought into the database by a message-retrieval process (32) of the arrangement.

If  the  call  is  directed to  a portable number,  a release message containing an indication that the called party number is a portable number and containing new routing information is forwarded from the terminating office to the originating office.  A new IAM is then sent from the originating office to a terminating office associated with the routing information.

Granted: 2000-03-28
Abstract: A modular jack telephone-type connector has a housing which is associated with a carrier on which metal conductors are mounted on a top surface thereof. A wire positioning fixture, which has wire openings for inserting electrical wires and a cavity for receiving terminals of the conductors, is supported in a hole on the top carrier surface allowing the fixture to move vertically in the hole with respect to the carrier. Vertical fins, which are mounted on the carrier, mate with vertical grooves, which are provided on an opposite side of the wire openings of the fixture, for additional secure positioning. A lever, which is pivotable on the housing, rotates toward or away from the carrier, and is coupled to the fixture via an interlock mechanism in order to transmit a rotational lever motion to the vertical fixture motion. As the lever rotates toward the carrier and pushes the fixture downward, wires inserted into the fixture precisely meet terminals, which extend through the cavity of the fixture. Slicers, provided on the terminals, remove the insulation from the wires ensuring good electrical contact between the wires and the terminals without using special termination tools.
