Abstract: A device is designed to remove blockages in a lumen such as a thrombus, blood clot, or embolus. The device comprises a manipulating wire and a structure that can conduct electrical current to a lumen blockage. The electrical current is preferably in radio frequency (RF). The RF electric current in the blockage can excite the contents such as proteins of the blockage, so that cross-linking density and interfacial adsorption of the entire blockage is enhanced. The enhanced cross-linking density can result in increased fracture resistance of the blockage such that fracture of the blockage during the removal process is unlikely. The enhanced interfacial adsorption results in increased interfacial fracture resistance between the device and blockage so that the blockage can be securely captured during the removal process without using radially applied force.

Abstract: The claimed biocompatible device is designed to remove vessel occlusions such as a thrombus, blood clot, or embolus. The claimed devices maybe used to treat occlusions in the brain, in the vasculature, and in tissues and organs. The device is in a form of a wire or wire-like structure which can capture the occlusion with minimal contact force with the vessel wall by an application of electricity, or electrical, chemical, or microwave generated heat to enable capture of the occlusion by the device. The device, compared to conventional mechanical thrombectomy devices, captures the occlusion and reduces occlusion fragmentation without large radial force and vessel wall friction that can damage the vessel wall.

Abstract: A push messaging platform includes a push server system having push engines (PE) for maintaining persistent connections with mobile devices, and push controllers (PC) for maintaining records of mobile devices' connections. The platform provides high scalability by including a load balancer for distributing connection requests received from mobile devices across the PEs, and dispatchers for forwarding each received message to a PC associated with the mobile device identified in the message.

A global registered process (GRP) on each PC is linked to a process on a backup PC, and the backup process replaces the GRP if the GRP fails. Local registered processes (LRP) on each PC are linked to corresponding processes on a remotely located mirror PC, and the mirror process replaces the LRP if the LRP fails.

Abstract: This invention discloses a system for line powering in communications. The system for line powering includes a power supply at the central office and remote power supply units (PSUs) connected to the power supply, wherein the power supply at the central office comprises at least two central office PSUs, and the central office PSUs provide power for the remote PSUs after being connected in parallel. At least two central office PSUs are set and connected in parallel to provide power for the remote PSUs, which provides redundant power backup for the remote PSUs and ensures reliability of normal communications in the network communication system. This method also helps to reduce the number of PSUs at the central office power supply part, to save space of the equipment room and to facilitate monitoring of central office PSUs. Thereby, this solution achieves reliable communication services, high integration of central office equipment and cost-effective network communication system.

Abstract: A system for line powering includes at least one office-end PSU, one standby PSU and one power switching unit. The office-end PSU provides power for a group of subscriber lines in a centralized manner. The power switching unit monitors the power supply status of the office-end PSU and controls the switching between the office-end PSU and standby PSU. In embodiments of the invention, different rectifier/boost circuits and different step-down circuits need not be set for each pair of subscriber lines between the office-end PSU and the remote device. When an office-end PSU fails to supply power, the standby PSU can be switched over quickly to supply power for the remote device, which cuts down the cost for designing the office-end PSU and the standby PSU while ensuring the reliability of power supply for the remote device.

Abstract: A symmetric dual-voltage charge pump and its control circuit generate bipolar output voltages. The charge pump converts a unipolar power source to a set of dual-voltage outputs of opposite polarity that are completely independent of each other. The charge pump includes two voltage-boosting transfer capacitors and two output capacitors. Two-phase operation generates an increased-magnitude output voltage of a negative polarity and another two phases of operation generate an increased output voltage of a positive polarity. The charge pump selectively charges one or both of the bipolar outputs with individual 2-phase charge cycles or with a sequence of charge cycles. When controlled by comparators with unequal reference voltages, the charge pump can force the bipolar outputs to unequal positive and negative voltages. Charge pumping is faster since only 2 phases are needed for charging either the positive or negative output.
