The ability of an ultrasonic system to sweep and lock onto a resonance frequency of a blade subjected to a heavy load at startup is improved by applying a high drive voltage or a high drive current while systematically increasing the level of the applied signal. Increasing the drive signal to the hand piece results in an improved and more pronounced “impedance spectrum.” That is, under load, the increased drive signal causes the maximum phase margin to become higher and the minimum/maximum impedance magnitude to become more pronounced. Increasing the excitation drive signal to the hand piece/blade at startup significantly alleviates the limiting factors associated with ultrasonic generators, which results in an increase of the maximum load capability at startup.

An implantable medical device includes a porous metal foam or foam-like structure having pores defined by metal struts or webs wherein the porous structure has directionally controlled pore characteristics. The pore characteristics controlled include one or more of the metal structure porosity, pore size, pore shape, pore size distribution and strut thickness. The pore characteristics may vary in one or more directions throughout the structure. Preferably the pore characteristics are controlled to match the porous metal structure to various mechanical and biological requirements of different regions of the structure in order to optimize aspects of the implants performance and may vary not only over the surface of the porous structure but through the depth of the porous structure. The thickness of the porous metal structure may also be modified to establish a thickness profile that optimizes mechanical and biological requirements of the implants performance. Acetabular cup embodiments of the invention are described. Various methods of manufacturing implants having directionally controlled pore characteristics are described.

Standby computers are dynamically divided into groups according to the difference between the software thereof and the software required of a business system. When a computer is made available, the standby computers divided into groups by software structure are searched and an appropriate one is extracted to quickly complete the construction of the software environment. An active computer, if to be transferred to standby mode, is associated with the group having the same software structure as the business system with which the active computer has thus far operated. The active/standby states of the computers are monitored, and the standby computers are changed thereby to widen the possible range of application to other business systems, removing copy operation of disk images from the active computer to the standby computers.

Presented is a method and apparatus comprising one or more robotic members which are curvaceous or snake-like; having movable shapers through which may pass an articulable column having successive joints formed of alternating ball and socket members. The shapers can be directed up and down the articulable column, to create virtually any radius of curvature, in any direction. The robotic member may also include discrete microelectronic mechanical devices (MEMS) shapers with embedded addressable controllers. Thus the device, with computerized control is capable of negotiating a tortuous path to access the site of a given operation and to retreat along the same path, without injury to the body in which the arm is directed. Once at the work site, the articulating columns, or parts of them, may be put in compression, causing them to become rigid.

An aircraft comprises a wing tip device, for example a winglet, a raked-tip device, a wing tip fence or a planar wing extension, mounted in the region of the tip of a wing on the aircraft. The wing tip device is rotatably moveable between a first position and a second position, in which the upward lift produced by the wing or the wing tip device is reduced. During flight, the bending moment at the root of the aircraft wing therefore changes in dependence on the position of the wing tip device. The maximum bending moment in the aircraft wing sustained during high-load conditions is thereby reduced, allowing the structural mass of the aircraft to be reduced.
