20140077782 | SEMICONDUCTOR DEVICE INCLUDING SHORT-CIRCUIT PROTECTION - A semiconductor device is described that includes a switch to switch a load current path on and off according to an input signal. The device further includes an over-current detector to compare a load current with a threshold and to signal an over-current when the load current reaches or exceeds the threshold. The device further includes a control unit to set the threshold to a higher value while in a first state of operation and to a lower value while in a second state of operation, and to at least temporarily switch the switch off when an over-current is signalled, change from the first state of operation to the second state of operation when a first pre-defined time span has elapsed, and to change from the from the second state of operation to the first state when the switch is off for more than a second pre-defined time span. | 03-20-2014 |
20140078629 | SEMICONDUCTOR DEVICE INCLUDING SHORT-CIRCUIT PROTECTION - A semiconductor device includes a load current path operable to carry a load current from a supply terminal having a supply voltage to an output circuit node. The device further includes a voltage comparator configured to compare the supply voltage with a voltage threshold and to signal a low supply voltage when the supply voltage reaches or falls below the voltage threshold. An over-current detector is configured to compare a load current signal that represents the load current with an over-current threshold and to signal an over-current when the load current signal reaches or exceeds the over-current threshold. Furthermore, the semiconductor device includes a control logic unit that is configured to deactivate the load current flow when an over-current is signalled and to reduce the over-current threshold from a first value to a lower second value as long as the voltage comparator signals a low supply voltage. | 03-20-2014 |

20110046542 | APPARATUS AND METHODS FOR CLOT DISSOLUTION - Clot disruption and dissolution are achieved using a catheter having the ability to infuse a thrombolytic agent, aspirate clot and fluid, and allow passage of a guidewire. Optionally, the catheter may also include a mechanical agitator for further disrupt clot in the presence of the thrombolytic agent. A flow resistor in the catheter provides for infusion and/or aspiration to be concentrated primarily at a clot treatment area in a blood vessel while also providing optional infusion and/or aspiration distal to the treatment area. In some embodiments, infusion, aspiration and guidewire passage occur through a common lumen. The thrombolytic agent, such as tPA, streptokinase, or urokinase, is directly released into the clot at the point where the agitator is engaging the clot. In this way, the thrombolytic activity of the agent is enhanced and the dissolution of the clot is improved. | 02-24-2011 |

20100020691 | Actuator for implementing rate-based packet sending over packet switching networks - An actuator is disclosed which is required to implement, without errors, a generic rate-based packet sending algorithm over a packet switching network such as the Internet. Typical applications are audio/video streaming over UDP or TCP, audio/video conference over IP, Voice over IP, real-time data delivery, IP Television, Digital Video Broadcast over IP, client-server or peer-to-peer content distribution, Content Delivery Networks, Hybrid peer-to-peer/CDNs. Rate-based packet sending is of key importance for providing Quality of Service/Experience (QoS/QoE) over the Internet because it provides reduced queuing delays and jitters, and reduced buffer sizes both at application and network layers. | 01-28-2010 |
