摘要： Systems and methods are disclosed for in-line removal of duplicate network packets in network packet streams operating at high speeds (e.g., 1-10 Gbps and above). A hash generator applies at least one hash algorithm to incoming packets to form one or more different hash values. The packet deduplication systems and methods then use the one or more hash values for each incoming packet to identify data stored for previously received backs and use the identified data to determine if incoming packets are duplicate packets. Duplicate packets are then removed from the output packet stream thereby reducing duplicate packets for downstream processing. A deduplication window can further be utilized to limit the amount of data stored for previous packets based upon one or more parameters, such as an amount of time that has passed and/or a number of packets for which data has been stored. These parameters can also be selected, configured and/or adjusted to achieve desired operational objectives.
摘要翻译：公开的系统和方法用于在以高速（例如，1-10Gbps及更高）运行的网络分组流中在线去除重复的网络分组。散列生成器将至少一个散列算法应用于传入数据包以形成一个或多个不同的哈希值。然后，分组重复数据删除系统和方法使用每个输入分组的一个或多个散列值来识别为先前接收的背部存储的数据，并使用所识别的数据来确定传入分组是否是重复的分组。然后从输出分组流中删除重复的分组，从而减少用于下游处理的重复分组。可以进一步利用重复数据消除窗口来基于一个或多个参数（例如已经经过的时间量和/或数据已被存储的数据包的数量）来限制对先前分组所存储的数据量。也可以选择，配置和/或调整这些参数以实现所需的操作目标。

摘要： A digital camera is constructed with multiple lenses mounted in a pair of tubular elements which are nested together for relative axial movement. Movement is provided by piezoelectric actuators mounted externally to a support tube on flexible printed circuit board elements. Each lens tube is provided with a drive rail which extends at least partially over the length of the lens tube and projects radially outward from the periphery of each of the tubes.

摘要： An electromechanical actuator comprises at least two actuating portions of electromechanically active material extending by a generally elongated shape from a back portion. The actuating portions are bimorphs, attached by a first end to a first side of the back portion and positioned parallel to each other one after the other in a first direction. The bimorphs are arranged to provide movements of the second end along the first direction and along the extension of the actuating portion, thereby being able to move relative a body in the first direction. The actuating portions have generally flat internal electrode layers arranged inside the electromechanically active material directed substantially perpendicular to the first direction. The internal electrode layers extend continuously through the actuating portions and into the back portion.

摘要： An electromechanical motor according to the present invention has a stator with a drive element consisting of two serially connected bending sections and a central drive pad, for actuating on a body to be moved. The drive element extends parallel to the body. The drive pad and/or the body is elastic. Preferably, the drive pad has a lower stiffness than the body. The elasticity of the drive pad allows an assimilation of a part of the travelling wave energy applied to the drive element. The backbone of the stator is arranged to restrict the drive element from being removed from the body, but at the same time allow the drive element to be translated towards the body and even leave the mechanical contact with the backbone for shorter periods of time. Support means are preferably designed with convex surfaces in order to allow self-centering of the different parts of the motor.

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.
