Publication number: 20090046627Abstract: A method and system for controlling discontinuous reception (DRX) in a mobile device in a wireless communications network that supports voice-over-internet-protocol (VoIP) and that uses an automatic repeat-request (ARQ) method, like a hybrid automatic repeat-request (HARQ) method, uses autonomous DRX control after initial VoIP traffic setup. If the mobile device transmits a negative-acknowledgement signal (NACK) indicating unsuccessful receipt of a VoIP packet, then it autonomously turns on a predetermined delay time later to receive the retransmission of the VoIP packet, where the predetermined delay time is related to the time for the base station to process the NACK and prepare the VoIP packet for retransmission. When the mobile device transmits or retransmits a VoIP packet, reception is deactivated, but is autonomously activated the predetermined delay time later to receive an acknowledgement signal (ACK) or NACK.Type: ApplicationFiled: August 13, 2007Publication date: February 19, 2009Applicant: SHARP LABORATORIES OF AMERICA, INC.Inventor: Shugong Xu

Publication number: 20090047594Abstract: A developer according to the present invention is arranged such that the composition of particulate metal oxide added as an external additive to a toner surface and the composition of particulate metal oxide added to a resin layer covering a carrier surface are identical to each other, so that the amount of frictional charge that is generated between the toner and the external additive is made larger than the amount of frictional charge that is generated between the external additive and the carrier surface. With this, the external additive is prevented from migrating from the toner surface onto the carrier surface. This makes it possible to prevent the external additive from migrating from the toner surface onto the carrier surface, and thereby to remedy (i) defects in charge and fluidity and (ii) secondary failures, i.e., defects in development that are caused by deterioration in performance of the developer due to the defects in charge and fluidity.Type: ApplicationFiled: January 11, 2008Publication date: February 19, 2009Applicant: Sharp Kabushiki KaishaInventor: Hiroyuki Hirakawa
