20130155046 | Level Shifter With Low Voltage Loss - A system and method are disclosed for level shifting a DDC bus with a low voltage loss. A pull up circuit includes an NMOS transistor, a PMOS transistor and resistor. An NMOS pull up gate is also included in line with the DDC bus. When powered, the level shifter adjusts the voltage of transmitted signals to match the voltage of a receiving device. The resulting adjusted is slightly lower due to a threshold voltage lost across one or more transistors. Additionally, when unpowered, the level shifter releases the signal transmission line. Unadjusted signals can then be transmitted without consumption of power by the level shifter. | 06-20-2013 |
20140105078 | Method for Switching Working Mode on Relay Network, Base Station, Relay Node, and Communications System - The present invention provides a method for switching a working mode on a relay network, a base station, a relay node, and a communications system. A donor eNB (DeNB) sends an RN reconfiguration message to a relay node RN in frequency division duplex FDD mode, so that the RN switches from the FDD mode to a half-duplex frequency division duplex H-FDD mode. The DeNB receives an acknowledgment message sent by the RN in FDD mode. When the DeNB verifies, according to the RN reconfiguration message and the acknowledgement message, that the RN has already started to switch from the FDD mode to the H-FDD mode, the DeNB switches from the FDD mode to the H-FDD mode. | 04-17-2014 |
