Publication number: 20030039351Abstract: An equalizer for a loudspeaker telephone includes a signal generator for generating a reference signal for broadcast by a loudspeaker of the loudspeaker telephone. A filter alters the frequency response of signals prior to broadcast by the loudspeaker. During set-up, a processor processes the reference signal picked up by a microphone remote from the loudspeaker that has been convolved with the acoustical response of the environment to determine coefficients for the filter that are necessary to compensate for the environment acoustics and applies the coefficients to the filter.Type: ApplicationFiled: June 26, 2002Publication date: February 27, 2003Applicant: Mitel Knowledge CorporationInventor: Philippe Moquin

Publication number: 20020095293Abstract: A method of initiating a data session between a wireless device and an information network over a wireless communication link includes establishing a voice session between the wireless device and a voice recognition application over the wireless communication link. A speech request is conveyed to the voice recognition application for information to be obtained from the information network. The voice recognition application converts the speech request into search criteria. A search of the information network is then initiated using the speech criteria and the voice session is terminated. A data session is then established with the wireless device and the search results are pushed to the wireless device over the wireless communications link.Type: ApplicationFiled: June 29, 2001Publication date: July 18, 2002Applicant: Mitel Knowledge CorporationInventors: Warren Gallagher, Lisa Fast, Shawn Griffin

Patent number: 6363140Abstract: Dialable user profiles are established via a software user agent in a telecommunications system for filtering mixed-media messages, including electronic mail and voice mail. According to the software agent of the present invention, the user creates, stores and retrieves a plurality of user profiles which indicate how inbound messages are to be sorted and prioritized. The user selects and invokes a particular profile which is appropriate to a given situation, such as remote computer dial up, pay phone dial up, cellular dial up, etc. The user agent resides in a message server of the data communication network and interprets commands from the user via remote terminal or touch-tone pad to retrieve and apply the requested profile.Type: GrantFiled: July 23, 1998Date of Patent: March 26, 2002Assignee: Mitel KnowledgeInventor: Debbie Pinard

Publication number: 20020028107Abstract: An adjunct part can be secured to a host part, where the host part defines a recess configured to allow a threaded fastener to secure the host part to a further part. The adjunct part has a resilient boss projecting therefrom and adapted to enter the recess, the boss having an axially extending opening to receive a threaded tightening member. The boss and the threaded tightening member have configurations which allow the tightening member, as it advances into the boss along the opening, to resiliently urge portions of the boss radially outward into binding contact with the interior of the recess, thereby fastening the adjunct part to the host part.Type: ApplicationFiled: July 18, 2001Publication date: March 7, 2002Applicant: Mitel Knowledge CorporationInventors: Peter Mathieson Craig, Julia Turner

Publication number: 20010036260Abstract: A multi-frequency tone detector with analysis window (i.e. filter size) chosen such that spectral nulls are located at adjacent frequencies of interest. The decision logic block of the tone detector uses the roll-off characteristics of the filter in conjunction with background noise to determine a threshold pass/fail for any tone that has deviated excessively from its nominal value. The foregoing aspects of the invention result in simple filter design (i.e. reduced order) relative to prior art tone detectors.Type: ApplicationFiled: March 15, 2001Publication date: November 1, 2001Applicant: Mitel Knowledge CorporationInventor: Dieter Schulz

Publication number: 20010031047Abstract: A line circuit utilizing a differential amplifier whose output is regulated to zero volts D.C. (when the subscriber's set is off-hook) by a negative feedback circuit, for controlling a voltage controlled power supply which provides a constant current feed to the subscriber's loop. The differential amplifier also transmits audio signals received from the subscriber's loop directly to a PABX via an unbalanced terminal. When the loop range exceeds a predetermined threshold, the circuit reverts to a voltage feed operation thereby allowing operation over long loop lengths and the ability to provide on-hook CLASS services.Type: ApplicationFiled: March 30, 2001Publication date: October 18, 2001Applicant: Mitel Knowledge CorporationInventor: Chuk Seto
