LBT interface for logical DTX
Methods, systems, and devices for wireless communication are described. A base station may support layer-to-layer listen-before-talk (LBT) interfacing for logical discontinuous transmission (DTX) events. That is, a layer one entity of the base station may indicate to a higher layer that a channel is unavailable or experiencing high levels of interference. For example, a layer one entity of the base station may perform a failed clear channel assessment (CCA) or LBT procedure on the channel. The layer one entity may then convey an indication that a scheduled message was not successfully transmitted to a higher layer (e.g., a media access control (MAC) layer that performs link adaptation and scheduling). The higher layer may schedule a retransmission of the message based on the indication. In some cases, the same link parameters may be used. In other cases, the link parameters may be updated based on channel conditions. |

Cloud powered system enabling mobile devices to control peripherals without drivers
Smart devices including smart phones and tablets are getting more powerful and become versatile enough to replace conventional personal computers. Despite the rapid evolution of capabilities of such devices, controlling peripherals such as networked printers is infeasible due to lack of dedicated drivers to communicate with peripherals. To immediately enable smart devices to operate peripherals, a cloud-powered system, CloudBridge, is suggested. A CloudBridge application miming on a smart device works as a TCP bridge relaying packets between two TCP tunnels connected to a networked peripheral on one side and a cloud server on the other side. Through the bridge, issuing operations from a smart device without having drivers becomes possible by asking the cloud server to interpret the operations to a language that the peripheral can understand, CloudBridge further optimizes user experience by using data compression that is adaptively applied by a decision function. The system implemented in Android phones and Linux servers is demonstrated to control networked printers on smart phones and tablets. The decision function is shown to optimize QoE metrics, such as response time and energy consumption though extensive evaluations. |

Semiconductor device with field threshold MOSFET for high voltage termination
This invention discloses a semiconductor power device disposed in a semiconductor substrate comprising a lightly doped layer formed on a heavily doped layer and having an active cell area and an edge termination area. The edge termination area comprises a plurality P-channel MOSFETs. By connecting the gate to the drain electrode, the P-channel MOSFET transistors formed on the edge termination are sequentially turned on when the applied voltage is equal to or greater than the threshold voltage Vt of the P-channel MOSFET transistors, thereby optimizing the voltage blocked by each region. |
