摘要： In a method according to the present invention, charging and discharging of motor phases (10A, 10B) in an electromechanical motor is performed with a small voltage difference between the voltage source and the capacitive load of the motor phase (10A, 10B). This is accomplished by connecting a series of voltage sources (36), one at a time. Energy from the discharging operation is stored to be used in subsequent charging operations. In a device according to the present invention, the voltage sources (36) are preferably provided by means of capacitive or induction voltage step-up or step-down circuits. Preferably, switches (34) control the charging and discharging. In a preferred embodiment, the capacitance of one motor phase (10A) is used for storing charge resulting from the discharge from another motor phase (10B).

摘要： The present invention discloses an electromechanical actuator arrangement (10) and a method for driving such arrangement, having a plurality of drive elements (14a-d) according to a walking mechanism in a motion relative a body (22). A driving portion of the drive elements (14a-d) are independent movable tangentially and normally to the body (22) surface. The drive elements (14a-d) are driven in the fours cycle steps; gripping, moving the body, releasing and returning to the original position. The drive elements (14a-d) are divided into two exclusive sets. The driving of the sets is phase shifted. At least one of the sets is in contact with the body (22) surface at each instant. The present invention is characterised in that the driving of the drive elements (14a-d) during the gripping sequence is performed in such a way that the drive elements (14a-d) have a velocity, which has a significant tangential component.

摘要： Systems and methods are disclosed for mobile user identification and tracking for load balancing in packet processing systems. Packet processing systems, such as network tool optimizer (NTO) systems, are configured to receive packets associated with multiple mobile users, to extract user identification information from the packets, to store identity binding information for the mobile users, to track changes in identification information for mobile users within a communication system by analyzing control information within packets for the communication system, and to forward packets to one or more tool ports associated with the packet processing system. The packet processing systems disclosed thereby allow for user packets to be identified and sent to the same load-balanced network tool, even though the user identification information changes over time within the communication system. The disclosed embodiments are useful for a wide variety of mobile and/or non-mobile communication systems and related communication protocols.

摘要： A control valve for a double acting type Stirling engine of the type having two or more piston assemblies reciprocating in bores with each of the piston assemblies separating isolated volumes of a working gas. The control valve provides the functions of a check valve which allows an internally defined volume within the engine to be held at a low pressure near the minimum pressure of the cycle volumes. The valve may further be actuated to unload the engine to provide low starting torque and to unload the engine in case of an engine or load malfunction. The control valve further provides a controlled leakage path for working fluid flowing between the cycle volumes and the minimum pressure volume which acts as part of a pressure balancing system for the Stirling engine which maintains the volume or mass of a working fluid in a balanced condition between the cycle volumes.

摘要： The present invention overcomes the problem of S1 interface failure by redirecting user equipments to another radio basestation, or another RAT. This redirecting may be on a UE-by-UE basis, i.e. when a connection request is received, redirecting that UE, or may involve redirecting all UEs in a cell by broadcasting modified system information. The redirecting may be such that future traffic load, for example as caused by UEs performing tracking area updates, is minimized, by instructing UEs to redirect after a randomized period of time, or by locking the cell after a randomized period of time, for example. In yet further embodiments of the invention, the cell may be locked after a certain number of connection requests have been received. In this way, particularly busy cells can be locked sooner than would otherwise be the case.
摘要翻译：本发明通过将用户设备重定向到另一个无线电基站或另一个RAT来克服S1接口故障的问题。这种重定向可以在UE-by-UE的基础上，即当接收到连接请求时重定向该UE，或者可能涉及通过广播修改的系统信息重定向小区中的所有UE。重定向可以使得例如由执行跟踪区域更新的UE引起的未来业务负载被最小化，通过指示UE在随机化的时间段之后重定向，或者通过在随机化的时间段之后锁定小区，例如。在本发明的另外的实施例中，在接收到一定数量的连接请求之后，单元可以被锁定。这样，特别忙碌的单元可以比其他情况更快地被锁定。

摘要： Aspects of the present invention relate to improved systems and methods for handing over a UE from a source node to a target node. In some embodiments, the target node receives UL and DL count information directly from the UE being handed over, rather than from the source node or from a core network node.
