Title: Telecommunications system with active database
Inventor: PENZIAS ARNO ALLAN
IPC: H04M1/274
Filed: 1994-01-17
Granted: 1998-08-25
Abstract: Intexchange carriers make their rate information for long-distance service available in a database 16. PBXs 40 and telephone central offices 31 access that rate information using ISDN and/or SS7 signaling and use it as a basis for determining which carrier to use at any given time in the routing of a call. Such accessing may be carried out on a call-by-call basis. Or a carrier's schedule of rates can be stored locally in the PBX or local switching office, thereby obviating the need for a database query for every call.

Title: Speech decoder capable of reproducing well background noise
Inventor: OZAWA KAZUNORI
IPC: G10L19/08
Filed: 1994-12-06
Granted: 1998-11-24
Abstract: When background noise is superposed on speech, a speech decoder can well represent the background noise through signal processing only in the speech decoder even at low bit rates.  In the speech decoder, a decoding circuit receives a signal from a speech coder, a speech detecting circuit detects non-speech and speech intervals, and a excitation signal calculating circuit calculates a excitation signal using a sound source signal, a pitch period, and an average amplitude.  A signal reproducing circuit drives a filter composed of a spectrum parameter to reproduce a sound signal.  A searching circuit stores a set of random number code vectors of a predetermined bit number as a code book, and searches the code book for a best random number code vector which is selected.  A second signal reproducing circuit reproduces a sound signal (noise) using the selected random number code vector.

Granted: 2007-01-30
Abstract: The invention concerns a method and apparatus for classifying particles, and in particular for classifying particles according to whether they are diamond or non-diamond particles. In the method each particle (24) is irradiated with a pulse of monochromatic light capable of causing Raman spectral activation in certain particles. Light emitted by the particle is filtered to remove components which are outside a band including a characteristic Raman spectrum for the relevant class of particles. The filtered light is direct onto a light sensitive switch (26) which is arranged to close on receipt of filtered light of predetermined intensity. On closure of the light sensitive switch, an electrical pulse is generated and directed towards a pulse detector (32). The particle is classified according to whether or not the pulse detector (32) detects an electrical pulse within a predetermined time window. The original pulse of monochromatic light can be split into a test portion, used to irradiate the particle, and a control portion used to control a time gating apparatus which sets the time window. The method can be used in a particle sorting method in which, typically diamond and non-diamond particles are separated from one another.

Abstract: A valve for a vacuum die casting machine has a cover die block and as ejector die block. A slotted member and an abutting slotless member abutting said slotted member are movable between an open, fluid-passing position and a closed, fluid-blocking position. A controller directs movement of the valve between the open and closed positions.      The valve is moved to its open position as the air within the cavity and associated lines is being evacuated and is moved to its closed position as the shot is injected into the die cavity. The slotted and slotless members may either be rotatable drums or elongated bars. The slotted drum includes a slotted end and an actuation end. Similarly, the slotted elongated bar includes a slotted end and an actuation end.      Alignment of the slot of either the rotatable slotted drum or the movable slotted bar with the vacuum passage allows the passage of fluid.

Title: Low profile ostomy system with repositionable pouch
Inventor: KUCZYNSKI THOMAS J
IPC: A61F5/443
Filed: 1997-02-26
Granted: 2005-06-14
Abstract: The low profile ostomy system includes an adhesively securable repositionable pouch that bonds to a body-side mounting wafer. The repositionable pouch is removable from the mounting wafer for repositioning if necessary. In a preferred embodiment of the invention, a resealable tape, which is in the form of a foam tape, is located on a face plate of the pouch and a releasable film, which is backed by a foam tape, is located on a body-side mounting wafer. The face plate of the pouch is formed with an extension tab that is accessible before and after the pouch has been secured to the body-side mounting wafer. The extension tab facilitates peeling of the face plate from the body-side mounting wafer during removal of the pouch from the mounting wafer. The foam tape on the body-side mounting wafer and the face plate inhibit formation of wrinkles or kinks at the engagement surfaces of the face plate and body-side mounting wafer when the pouch is removed from the body-side mounting wafer.

Title: Magnet-controlled rowing exerciser
Inventor: WANG LEAO
IPC: A63B21/005
Filed: 1997-04-10
Granted: 2006-07-11
Abstract: The present invention relates to a magnet-controlled rowing exercisor which utilizes an adjustable magnet-controlled wheel mechanism such that the user can adjust resistance in exercise. A magnet controlled wheel mechanism includes a magnet conductive fly wheel and cooperating magnet set for providing variably adjustable resistance. The mechanism further includes a coaxially mounted leading wheel for securing an end of the pulling string in a spiral configuration and a spiral spring for exerting a counter-rotational force on the leading wheel. In use rotation of the leading wheel caused by extending the string creates tension in the spiral spring sufficient to retract the string for repeated motion. The magnetic resistance has the advantage of being less subject to fatigue than common known devices, quieter that prior art devices and more easily adjustable in resistance.

Abstract: At the beginning of each time trial a vector of measurement values and a vector of measurement plausibility values are supplied to a system (10), and a learning weight is either supplied to or generated by the system (10). The system (10) then performs the following operations during each time trial: convert-ing the measurement values to feature values; convert-ing the measurement plausibility values to feature vi-ability values; using each viability value to determine missing value status of each feature value; using non-missing feature values to update parameter learning; imputing each missing feature value from non-missing feature values and/or prior learning; converting im-puted feature values to output imputed measurement values; and applying a variety of feature values and feature function monitoring and interpretation statis-tics. A parallel embodiment of the system (10) per-forms all such operations concurrently, through the coordinated use of parallel feature processors (31) and a joint access memory (23), which contains connec-tion weights and provision for connecting feature pro-cessors pairwise.
