Publication number: 20110153842Abstract: A control device, which is for use during multimedia streaming between a user terminal and a base station over a wireless broadband network, includes a parsing unit, a computing unit and a processing unit. The parsing unit parses a session signal for establishing a multimedia streaming session so as to acquire a call ID and a media descriptor of the multimedia streaming session. The computing unit receives the media descriptor thus acquired by the parsing unit, and computes a bandwidth needed for the multimedia streaming session based on the media descriptor. The processing unit receives the call ID and the bandwidth, and transmits a quality-of-service request signal to the base station according to the bandwidth and corresponding to the multimedia streaming session so as to request the base station to provide a quality of service corresponding to the bandwidth during the multimedia streaming session.Type: ApplicationFiled: September 15, 2010Publication date: June 23, 2011Applicant: GEMTEK TECHNOLOGY CO., LTD.Inventors: Cheng-Yuan Chuang, Yi-Ping Tsai

Publication number: 20110110297Abstract: A wireless broadband subscriber equipment with network quality management capability includes a parsing unit, a quality-of-service (QoS) controller, and a grant controller. The parsing unit receives a session signal containing session-establishing information, and parses the session signal to obtain a control signal. The QoS controller sends to a base station a QoS request signal corresponding to the control signal. The grant controller receives a response of the base station to the QoS request signal, is configured to forward the session signal to an intended recipient of the session signal when the response of the base station indicates that the base station is available to establish a session conforming to the QoS request signal, and to send a busy notification to a sender of the session signal when the response of the base station indicates that the base station is unavailable to establish the session conforming to the QoS request signal.Type: ApplicationFiled: June 4, 2010Publication date: May 12, 2011Applicant: GEMTEK TECHNOLOGY CO., LTD.Inventor: Cheng-Yuan Chuang

Patent number: 7797968Abstract: Circular knit, elastic fabrics of at least one of single jersey, French terry, and fleece are disclosed that include a bare elastomeric material plated with spun and/or continuous filament hard yarns. The circular knit, elastic fabrics of at least one of single jersey, French terry, and fleece are manufactured by a method that does not require a dry heat setting step. The method requires drafting the bare elastomeric material no more than about 7× its original length when knitting to form the circular knit, elastic, single jersey, French terry, or fleece fabric. The method includes contacting the knit fabric with an aqueous solution under very low tension and under conditions of temperature and pressure for a period of time sufficient to substantially set the elastomeric material.Type: GrantFiled: August 12, 2005Date of Patent: September 21, 2010Assignee: INVISTA North America s.à.r.l.Inventors: Cheng-Yuan Chuang, Graham H. Laycock, Raymond S. P. Leung, Peter George Szanto, Fred Wynegar

Patent number: 7779655Abstract: The invention provides a method for knitting fabric with bare spandex comprising: providing bare spandex yarn; providing hard yarn; drafting the bare spandex; knitting fabric from the hard yarn and the drafted bare spandex with the hard yarn and the drafted bare spandex plated in every course; and contacting the knit fabric with a continuous phase aqueous solution under conditions of temperature and pressure for a time sufficient to set the bare spandex without heating the knit fabric on a tenter frame above 160° C. in air having a relative humidity of less than 50%. The invention further provides a bare spandex-containing knit fabric containing spandex in every knit course that has been exposed to manufacturing process temperature no higher than 160° C. as shown by molecular weight analysis of the spandex and that exhibits wash shrinkage of less than about 14%.Type: GrantFiled: December 16, 2005Date of Patent: August 24, 2010Assignee: INVISTA North America S.á r.l.Inventors: Cheng-Yuan Chuang, Graham Laycock, Raymond S.

Patent number: 7634924Abstract: Circular knit, elastic fabrics of at least one of single jersey, French terry, and fleece are disclosed that include a bare elastomeric material plated with spun and/or continuous filament hard yarns. The circular knit, elastic fabrics of at least one of single jersey, French terry, and fleece are manufactured by a method that does not require a dry heat setting step. The method requires drafting the bare elastomeric material no more than about 2.5× its original length when knitting to form the circular knit, elastic fabrics of at least one of single jersey, French terry, and fleece.Type: GrantFiled: August 12, 2005Date of Patent: December 22, 2009Assignee: Invista North America S.ár.l.Inventors: Cheng-Yuan Chuang, Graham H.
