摘要:
An assembly of a cable gripper and a cable that has an outer protective layer formed from plastically deformable material, over an inner tensile strength portion). The cable gripper includes at least one gripper member having a supported outer end and an active inner end penetrating the outer protective layer and gripping the inner tensile strength portion beneath the outer protective layer. The active inner end includes a material of sufficient hardness to penetrate the outer protective layer by movement of the gripper member through the outer layer from an inoperative to an operative position.
摘要:
With one known cable gripper device, when the gripper device contacts the outer surface of a submarine telecommunications cable, there is a problem of insufficient friction between the cable layers being acted on by the gripper, and/or insufficient adhesion between the cable layers along the cable from the gripper to the free end of the cable, and consequently there is a tendency for the protective outer sheath to be stripped from the core during recovery, with the result that the engaged end is lost. The cable grippers (100) of this invention are able to penetrate the outer protective layer and to grip the inner tensile strength core of cable. They may have at least one pair of co-operative gripper members (15a, 15b), the inner ends of which are profiled to together define a pre-shaped gripper for secure engagement of cable, providing an inner region to receive and retain the inner tensile strength portion

A program controller is arranged to automatically authorize or configure or upgrade a program for a customer replaceable card of a system, the controller being arranged to manage the program automatically, according to a licence agreement, and according to a stored history of use of the hardware module. A supplier can track customer changes and enforce more easily different conditions for authorizing the program on, different modules from different sources, having different levels of capability. There can be less interaction with the supplier to get specific authorizations. The history can be stored on the module. It can be used to ease inventory tracking and generate billing information.
摘要:
In embodiments of the present invention improved capabilities are described for providing data protection through the detection of tags associated with data or a file. In embodiments the present invention may provide for a step A, where data may be scanned that is intended to be communicated from the client computing facility. In response to step A, at step B, restricted data may be identified by identifying an absence of a tag associated with the data. And finally, in response to step B, at step C, an interruption to the intended communication may be caused.

In embodiments of the present invention improved capabilities are described for presenting a physical computing machine including a virtual computer machine monitor and a one or more of virtual computing machines, where each of the virtual computing machines runs its own operating system, presenting one of the multiple virtual computing machines as a host, and the remaining multiple virtual computing machines as guests, and providing for a virtual machine protected environment, where suspicious file information is shared between the virtual machine protected environment and other virtual machines.
摘要:
A passive acousto-optic modulator for the modulation of a light beam as a function of a variation in air pressure comprising a beam splitter arranged relative to the beam so as to produce a signal beam and reference beam, the beam splitter ideally comprising a flat interface located between two optically transparent mediums such as the end of an optic fiber located within air, the interface being arranged relative to the light modulator such that when the light beam travels through the interface, some of the light beam is able to pass through the interface to form the signal beam, the rest of the light beam being reflected back off the interface to form the reflected reference beam; a light modulator which modulates the signal beam, the light modulator comprising an approximately flat optically reflective surface capable of movement, the reflective surface being located in a position which, at rest is a predetermined distance from the beam splitter and is approximately parallel to and facing the beam splitter and a piezoelectric element, the piezoelectric element being connected to the reflective surface in such a way that when an electric potential is applied across the piezoelectric element, it causes the reflective surface to move; and conversion means to convert variations in air pressure into corresponding variations in a signal for driving the light modulator; the arrangement being such that the modulated signal beam is combined with the reference beam to produce constructive or destructive interference.
