20140051908 | Hemodynamic Assist Device - A hemodynamic flow assist device includes a miniature pump, a basket-like cage enclosing and supporting the pump, and a motor to drive the pump. The device is implanted and retrieved in a minimally invasive manner via percutaneous access to a patient's artery. The device has a first, collapsed configuration to assist in implantation and a second, expanded configuration once deployed and active. The device is deployed within a patient's aorta and is secured in place via a self-expanding cage which engages the inner wall of the aorta. The device includes a helical screw pump with self-expanding blades. Also included is a retrieval device to remove the hemodynamic flow assist device once it is no longer needed by the patient. Also included is an arterial closure device to close the artery access point after implantation and removal of the hemodynamic flow assist device. The hemodynamic flow assist device helps to increase blood flow in patients suffering from congestive heart failure and awaiting heart transplant. | 02-20-2014 |

20110029790 | System and Method for Policing Bad Powered Devices in Power Over Ethernet - A system and method for policing bad powered devices in power over Ethernet. Degradation of components within powered devices can lead to noise and ripple that exceed specified thresholds. This noise and ripple can adversely impact the operation of the power sourcing equipment. A noise detector implemented in the power sourcing equipment can detect the presence of such noise and ripple and modify the application of power to the particular port. | 02-03-2011 |
20110283118 | Adaptive power sourcing equipment and related method for power over ethernet applications - There is presented a circuit and a related method for adaptively supplying Power over Ethernet (PoE) by a power sourcing equipment. The circuit comprises first and second power channels coupled to first and second network interfaces of the power sourcing equipment. A shunt device is operated to identify a maximum power characteristic of a powered device. The first power channel provides a first current to the powered device through the first network interface if the maximum power characteristic does not exceed a power threshold. The circuit provides another current to the powered device through the first network interface if the maximum power characteristic is greater than the power threshold. Various embodiments of the present invention may provide a second current to another powered device through the second network interface if the maximum power characteristic of the first and second powered devices does not exceed the power threshold. | 11-17-2011 |
