Patent number: 9363296Abstract: A digital broadcast communication system includes a transceiver configured to receive a digital packet containing a payload having voice content and to add a user's voice to the received voice content to create a combined voice content signal. The combined voice signal packet is then forwarded upstream to the network master wherein other similar devices may combine additional voice inputs. The system includes a buffer for canceling previously transmitted voice from a packet produced by the network master and adding a current most voice input from playback through a speaker.Type: GrantFiled: January 3, 2014Date of Patent: June 7, 2016Assignee: Havenet Technologies, Inc.Inventor: Seung Moon Ryu

Publication number: 20100203835Abstract: In wireless devices for transmitting/receiving at least one of broadcasting, communication and controlling, a wireless network protocol transmits repeatedly data structure with a certain period in a unit of the same cycle, and maintains synchronization of the devices in a unit of the same cycle. As a result, a frequency hopping is performed in a unit of a cycle. Here, length of the cycle is set to below 20 msec so that a buffer used for transmitting/receiving a broadcasting signal and a voice/data communication has length of below 20 msec. Cycles form a network cycle. Control frames included in the cycles in the network cycle are differently assigned in accordance with their use, and so the control frames may be used for various controls. A payload frame in the cycle used by a user may be set freely in the range of length of the cycle.Type: ApplicationFiled: November 2, 2007Publication date: August 12, 2010Applicant: CASUH CORPORATIONInventors: Seung-Moon Ryu, Wan-Gyu Ju, Hae-Young Cho, Jae-Hyun Eom

Patent number: 6961305Abstract: Disclosed is a method for modulating data for a polarity alternated pulse width code division multiple access (PAPW/CDMA) system and a method for measuring a distance between communicating equipments using the PAPW/CDMA. The method for modulating data includes the steps of multiplying CDMA signals inputted from multiple channels by a selected mask pattern, selecting the mask pattern among predetermined mask patterns that have the least peak value, truncation of multiplied CDMA signals according to a predetermined magnitude of levels to form level-number-reduced signals, converting the level-number-reduced signals to pulse width to generate modulated signals having a constant level, and alternately switching a starting polarity of pulses of the modulated signals between “high” and “low”.Type: GrantFiled: June 27, 2001Date of Patent: November 1, 2005Assignee: Casuh CorporationInventor: Seung Moon Ryu

Publication number: 20040042530Abstract: The present invention, relevant to a procedure for modulating/demodulating with code-select/code-division multiple access, provides a technique of code-division multiple-access, in which information channels in number of N+1 are assigned to each of blocks that includes a unit of orthogonal signature pattern codes in number of 2N, which are generated to maintain orthogonality between information channels transferred. One of the orthogonal codes of 2N belonging to the block is selected as a digital bit value of N-numbered information channels among the assigned information channels, and the other digital bit value of the information channel is set by modulating data channels of N+1 after being multiplied by the selected orthogonal code. Therefore, it reduces the number of orthogonal codes to be transferred rather than the number of information channels, lessening mutual interferences between crowded users and downing a cost for fabricating a system.Type: ApplicationFiled: June 5, 2003Publication date: March 4, 2004Inventor: Seung-Moon Ryu
