Patent number: 7418040Abstract: A receiver 200 as a component in a wireless communication device 100 and a corresponding method are used for receiving a multi-carrier communication signal and determining a timing offset thereof. The receiver 200 comprises a controller 222 to perform a correlation on each of a plurality of sub-carriers comprising the multi-carrier signal to provide a plurality of timing offsets. A quality metric corresponding to each of the plurality of timing offsets may be employed to select the best timing offset. Alternatively, a set of timing offsets whose quality metric exceed a threshold may be averaged. Either the best or average timing offset is used for processing all the sub-carriers of the multi-carrier signal.Type: GrantFiled: May 30, 2003Date of Patent: August 26, 2008Assignee: Motorola, Inc.Inventors: Michael J.

Publication number: 20040121812Abstract: In performing speech or voice recognition, a start point (306) is identified (214). The mobile communication device is provided with an automatic voice recognition algorithm. In noisy environments, however, excess noise may cause the automatic voice recognition algorithm to falsely determine that the noise is speech. Including the noise that occurs before the user actually begins speaking substantially reduces the ability of the voice recognition algorithm to correlate the audio signal with a voice template. To eliminate the effect the noise preamble would have if included by the automatic speech algorithm, the mobile communication device is provided with a user interface (210) that allows the user to assert a speech interrupt (220), causing the start point to be reset (222) at the time the speech interrupt becomes active (306), thereby disposing of the noise preamble.Type: ApplicationFiled: December 20, 2002Publication date: June 24, 2004Inventors: Patrick J.

Patent number: 6487181Abstract: A communication device employs a method and apparatus for transmitting and receiving information in a time slot. When transmitting, the communication device generates user information symbols and positions the symbols in a first portion of the time slot. The first portion of the time slot occupies less time than the time slot. The communication device then transmits the user information symbols during the first portion of the time slot only. When receiving, a communication device decodes and then encodes a received time slot, presuming the received time slot is not a truncated time slot. The communication device determines an error metric for the encoded time slot and, based on the error metric, determines whether the encoded time slot is a truncated time slot. When the encoded time slot is a truncated time slot, the communication device processes the user information symbols in the received time slot.Type: GrantFiled: November 30, 1998Date of Patent: November 26, 2002Assignee: Motorola, Inc.Inventors: Christopher L.

Patent number: 6301517Abstract: An automated monitoring and notification system for use with a testing arrangement is able to identify “potentially faulty test sockets”. The system uses a set of pre-existing data contained in a manufacturing database regarding the number of device failures for each socket. A threshold number of consecutive device failures is used to flag a particular test socket as “suspect”. Another database, containing historical “failure” data for the test sockets is then queried upon identification of each “suspect”. When the number of “failures” for a “suspect” exceeds a predetermined threshold, the socket is identified as “potentially faulty” and an alarm is sent to the system user.Type: GrantFiled: March 10, 1999Date of Patent: October 9, 2001Assignee: Lucent Technologies, Inc.Inventors: Patrick J. Doran, Daniel Kern

Patent number: 6157844Abstract: A mobile communication device containing voice recognition capability is first enabled to perform voice recognition (102). The user then speaks the name of the party the user wishes to call (104), the name corresponding to a record the user has programmed into a memory of the mobile communication device. The mobile communication device then uses the output (106) of the voice recognition process to search the memory for a corresponding record (108). The record contains at least two calling numbers, each associated with a different mode of communication, such as dispatch and telephone communication. For a brief period of time after locating the record, the mobile communication device waits (118) for the user to initiate a call in the first communication mode (120) by, for example, pressing a dispatch call button (124). If, after a preselected duration of time has passed and no input is received from the user, the mobile communication device defaults to a second communication mode and makes a call (122).Type: GrantFiled: August 2, 1999Date of Patent: December 5, 2000Assignee: Motorola, Inc.Inventors: Patrick J. Doran, Douglas E. Ross, Sheetal Shah

Patent number: 5911124Abstract: A communication device (200) includes apparatus (210) that selectively applies echo cancellation in the processing of an audio signal (207). The audio signal is processed for echo cancellation, and a modified audio signal obtained (410, 420, 430). The energy content of the modified audio signal is compared (440, 450) with that of the original audio signal. When the energy content of the modified audio signal exceeds that of the original audio signal, the unmodified audio signal is selected instead of the modified audio signal for further processing (450, 460, 470).Type: GrantFiled: February 3, 1997Date of Patent: June 8, 1999Assignee: Motorola, Inc.Inventor: Patrick J.
