Title: Dynamic routing-administration
Inventor: BOGART FRANK JEFFREY
IPC: H04Q3/545
Filed: 1992-08-20
Granted: 1997-03-25
Abstract: Choice of what portions of a dialed number are important and what weight they carry in deciding how to route or otherwise treat a call is customized and made contextually dependent via a call-processing arrangement that uses stored definitions of syntax and grammar of the network numbering plan. The syntax definitions are reprogrammable definitions of individual symbol strings and include the string's associated virtual nodepoint index which indicates the string's influence on call treatment, an indicator of whether digit collection is to continue, an indicator of whether the VNI is to be combined with a VNI resulting from any preceding symbol strings in the dialed number, and an indicator of whether the VNI resulting from this symbol string is to be combined with a VNI of any succeeding symbol strings in the dialed number. The dialed number is parsed to identify therein all included symbol strings, and the definitions of the included symbol strings are used to selectively combine their VNIs to form a resulting VNI that specifies the route or other treatment for the call.

Title: Seal arrangement
Inventor: FORCH HANS
IPC: F16J15/3216
Filed: 1992-12-14
Granted: 2000-02-01
Abstract: Seal arrangement for the sealing of a reciprocating rod in a surrounding housing radially spaced therefrom includes a seal housing enclosing a sealing ring of polymeric material which has a radially movable sealing lip. The sealing ring is provided with an integrally formed auxiliary sealing lip which is forced in axial direction against the surrounding housing by a compression spring. A guide ring supports the sealing ring about the rod. The seal arrangement provides for low friction displacement of the seal in radial direction when the sealed medium is pressurized and is more easily manufactured and installed.

Title: Pump
Inventor: HANSEN BENT
IPC: F04C15/06
Filed: 1993-02-02
Granted: 2003-07-29
Abstract: A gear pump which is fitted with a magnetic coupling (6) to ensure against leaks uses circulation of the pump fluid to cool the magnetic coupling. The circula-tion is established by supplying the pump rotor (4) with radial channels (24) which terminate in recesses on the periphery of the rotor and which are connected to an axial channel (26) in the rotor shaft leading to the end of the shaft which is nearest the magnetic coupling. The fluid which is drawn through the channels (24) is mixed with the main stream of fluid in a sec-tion which is cut out of the wall of the pump chamber (16), and fresh cooling fluid is drawn via the chamber (40) to the radial gap in the magnetic coupling.
Patent CA-2097100-C (CA)
Inventor: MONETTE DANIEL A
IPC: F16H57/02
Filed: 1993-05-27
Granted: 1999-04-06
Abstract: An adaptor (25) is disclosed for use in mounting a transmission clutch housing (21) to a flywheel housing (11') wherein the flywheel housing defines a first bolt circle pattern (R1), and the clutch housing defines a second, substantially smaller bolt circle pattern (R2). The adaptor includes a first portion (27) and a second portion (29), the portions defining pluralities of bolt holes (37 and 43).  The first portion defines a forward surface (33) and the second portion defines a rearward surface (41), both surfaces coinciding with an imaginary transverse mounting plane MP.  The forward surface of the first portion engages a mounting surface (62) of the flywheel housing, while the rearward surface of the second portion engages a forward surface (54) of the clutch housing, such that the use of the adaptor (25) does not change the relative axial position of the flywheel housing and clutch housing, which would require a change in the configuration or length of the transmission input shaft (19).

Title: Apparatus and method for detecting magnetic electronic article surveillance markers
Inventor: CORDERY ROBERT A
IPC: G08B13/24
Filed: 1993-08-31
Granted: 2001-08-07
Abstract: Method and apparatus for detecting the presence of a magnetic marker in a dual frequency interrogation zone. A dual frequency field is generated to produce an interrogation zone wherein the higher frequency is substantially higher than the lower frequency. The signal generated by the magnetic marker is detected filtered and amplified. Time windows are selected at the expected pulse locations of the signal. The signals detected at the time windows are multiplied by a window function. The product resulting therefrom is averaged to produce a demodulated signal and the presence of a marker in the interrogation zone is determined by detecting the demodulated signal at the lower frequency of the dual frequency interrogation zone.

Title: Interactive computer system recognizing spoken commands
Inventor: MACK ROBERT L
IPC: G10L15/00
Filed: 1994-02-08
Granted: 1997-09-23
Abstract: An interactive computer system having a processor executing a target  computer program,  and having  a  speech  recognizer  for converting an utterance into a command signal for the target computer program.   The target computer program has a series of active program states occurring over a series of time periods.  At least a first active-state image is displayed for a first active state occurring during a first time period.  At least one object displayed in the first active-state image is identified, and a list of one or more first active-state commands identifying functions which can be performed in the first active state of the target computer program is generated from the identified object. A first active-state vocabulary of acoustic command models for the first active state comprises the acoustic command models from a system vocabulary representing the first active-state commands.  A speech recognizer measures the value of at least one feature of an utterance during each of a series of successive time intervals within the first time period to produce a  series of feature signals.  The measured feature signals are compared to each of the acoustic command models in the first active-state vocabulary to generate a match score for the utterance and each acoustic command model.     The  speech  recognizer  outputs  a  command  signal corresponding to the command model from the first active-state vocabulary having the best match score.

Abstract: A system and method for the detection and measurement of atmospheric air movement irregularities such as wind velocity vector, clear air turbulence, aircraft induced vorteces and turbulence, by means of electromagnetic waves. An air volume (10) un-der investigation is illuminated by a transmitter (1, 1A, 1B) with a beam of coherent electromagnetic energy (1E), and a resulting wave field (2E) is received and subsequently coherently demodulated and processed in process means to derive information on the existence of the said atmospheric irregularities and furthermore to give specific measurements of related parameters. At least one receiver (2, 2A, 2B) for said resulting wave field (2E), which is due to scattering in said air volume (10), is positioned at a bis-tatic location having a selected distance (2R) from said transmitter (1, 1A, 1B). Said electromagnetic energy (1E) is transmitted at microwave frequencies in a concentrated beam. Transmitter and receiver antennas (1A, 1B, 2A, 2B), respectively, are directed so as to cover said air volume (10) with a scattering angle (.THETA.) chosen to have such a (low) value that scattering from atmospheric irregularities in said air volume (10) has a higher power than noise sources in the system.
