Patent number: 8565145Abstract: A method for transmitting a communication generated by an originating device to a target device using a repeating device is provided. In the method the communication is transmitted from the originating device and received at the repeating device. A repeater request sequence is transmitted from the originating device and retransmitted from the first repeating device to the target device before the repeater request sequence is received at the first repeating device.Type: GrantFiled: December 15, 2010Date of Patent: October 22, 2013Assignee: Motorola Solutions, Inc.Inventors: Shakeeb Z. Khan, Joseph J. Medvid, III, Charles R. Ruelke, Richard S. Young, Branko L. Avanic, Lorenzo Cruger, Tan V. Dinh, Mahes M. Ekanayake, Armando J. Gonzalez

Patent number: 8295825Abstract: Methods of enabling late entry into an on-going spread spectrum call are described. A late join frame replaces, and has the same size as, a traffic frame. A late join slot in the late join frame contains sufficient information in preamble and sync subframes to permit a target to join the call. The traffic slots in the late join frame replicate data such that call quality of the call is substantially unaffected if one of the remaining traffic frames is not received. The preamble and sync subframes frequencies may be the same as, or different from, preamble and sync frames frequencies during a call establishment phase of the call. If different, the preamble and sync subframes frequencies are selected from one or more frequencies. Use of the preamble and sync subframes frequencies is compensated for when selecting the traffic slot frequencies to obtain uniform utilization of the spectrum.Type: GrantFiled: November 30, 2010Date of Patent: October 23, 2012Assignee: Motorola Solutions, Inc.Inventors: Ellis A. Pinder, Branko L. Avanic, Lorenzo J. Cruger, Tan V. Dinh, Mahes M. Ekanayake, Armando J. Gonzalez, Joseph P. Heck, Shakeeb Z. Khan, Joseph J. Medvid, III, Wayne M. Phang, Charles R. Ruelke, Dang N.

Patent number: 7383021Abstract: A technique for activating a transmit mode of a communication device (100) is provided encompassing the steps of generating a light signal on an outer surface of the communication device; inhibiting the light signal; and activating the transmit mode of the communication device in response to the light signal being inhibited. A communication device (100) operating in accordance with this technique includes a light transmitting device (108); and a sensor (110) for sensing light generated by the light transmitting device, the sensor disabling a transmit mode when light is detected and enabling a transmit mode when light is inhibited.Type: GrantFiled: July 28, 2004Date of Patent: June 3, 2008Assignee: Motorola, Inc.Inventors: Hiep T. Dang, Branko L. Avanic, John K. McKinney, Joseph J. Medvid, III, Wayne M. Phang, Kevin D. Walkup

Patent number: 7113804Abstract: A communication device (105) includes a first communication block (205) for operation within a first communication network (150); and a second communication block (210) for operation within a second communication network (160). The communication device (105) further includes an audio control (245) for at least one microphone (250). The audio control (245) is coupled to the first communication block (205) for receiving a first audio input for operation of the first communication block (205) and is coupled to the second communication block (210) for receiving a second audio input for operation of the second communication block (210). A low noise ground (315) is isolated from a common ground (320) of the communication device (105) to facilitate the sharing of the at least one microphone (250) between the two communication blocks.Type: GrantFiled: January 9, 2004Date of Patent: September 26, 2006Assignee: Motorola, Inc.Inventors: John McKinney, Branko L. Avanic, Hiep T. Dang, Joseph J. Medvid, Wayne M. Phang

Patent number: 7096025Abstract: A communication device (105,200) includes a cordless telephone (205) and a two way radio (210). The communication device (105,200) is adapted to place an active cordless telephone call in a low frequency mode in response to receiving an incoming two way radio communication. The communication device (105,200) is adapted to then establish communication within the two way radio communication. The communication device (105,200) periodically re-establishes the cordless telephone call to maintain communication with a cordless base station (120) until the two way radio communication is completed.Type: GrantFiled: December 11, 2003Date of Patent: August 22, 2006Assignee: Motorola, Inc.Inventors: Wayne M. Phang, Branko Avanic, Hiep T. Dang, Joseph J. Medvid, Dang N Vu, Kevin D. Walkup

Patent number: 6741844Abstract: A receiver (10) includes an antenna (12), a preselector (14), an amplifier (16), a mixer (18), a filter (20), a signal strength measurement circuit (22), a radio frequency signal detector (26), and a processor (24). The processor (24) is programmed to receive a signal indicator level (42) from the signal strength measurement circuit (22), generate an automatic gain control command (44) based on the received signal indicator level (42), and send the automatic gain control command (44) to the amplifier (16) to control a gain of the amplifier (16). The processor (24) is programmed to receive an off channel signal strength (48) from the radio frequency signal detector (26), compare the off channel signal strength (48) to one or more threshold levels, generate a filter command (46), and send the filter command (46) to the filter (20). The filter command (46) identifies a cutoff frequency for the filter (20).Type: GrantFiled: November 27, 2001Date of Patent: May 25, 2004Assignee: Motorola, Inc.Inventors: Joseph J. Medvid, Dang N. Vu, Branko Avanic

Patent number: 6055421Abstract: A radio receiver operates primarily in a first operating mode to process received signals (410). When a carrier signal detect is triggered while in the first operating mode (415, 420), the receiver temporarily operates in a second operating mode which has receiver parameters selected to reduce carrier detect falsing when compared to the first operating mode (430). Preferably, in the second operating mode, the receiver's frequency and time response characteristics are modified to facilitate carrier squelch detection. Carrier squelch is performed if a carrier signal detect is triggered while the receiver operates in the second operating mode (440, 450, 460, 470).Type: GrantFiled: October 31, 1997Date of Patent: April 25, 2000Assignee: Motorola, Inc.Inventors: Rajesh H.
