Abstract: A submersible habitat 100 for the repair of subsea cable 11, the habitat comprising a cable maintenance environment 108 being suitable for receiving a portion of the subsea cable under repair 115 while the subsea cable 11 is submerged. The submersible habitat further comprising raising and/or lowering component 25 configured for raising and/or lowering the submersible habitat 100 relative to the subsea cable 11. The entire repair is carried out within the submersible habitat 100 without the requirement to transport any portion of the subsea cable 11 to the surface.

Abstract: A constant velocity joint includes a shaft. The constant velocity joint also includes a boot member. The boot member covers a portion of the shaft. A corrosion resistant sleeve is disposed intermediate the shaft and the boot member. The sleeve includes a vent channel. The vent channel is formed only in an outer surface of the sleeve.

Abstract: A computer-implemented method of operating a user device to access data relating to at least one of a plurality of topics, the method comprising: transmitting from the user device a request for topic data; receiving at the user device, in response to the request for topic data, core topic data defining at least one property of the selected topic; storing the core topic data in a topic database associated with the user device; receiving at the user device supplementary topic data associated with at least the selected topic; and in response to a request to access the selected topic, outputting the core topic data and the supplementary topic data (for example to a user via a display). A corresponding method of operating a server is also disclosed, as well as a user device, a server and a system employing the above-mentioned methods.

Abstract: A method of adapting the output of commercially available dimmer switches for use with non-incandescent light sources. Commercially available TRIAC and SCR based dimmers (62) output a waveform where AC output is varied based on user input by adjusting duty cycle (71), or the portion of the AC waveform that is output to the electrical load (76), having undesirable effects on non-incandescent loads. This output is fed into two alternately charging and discharging energy storage devices (72, 75), generating a modified AC waveform whose amplitude is proportional to the duty cycle percentage of the incoming AC waveform from the dimmer. Charge and discharge switching is handled by two switches (73, 74), triggered by the natural oscillation of the incoming AC waveform.

Abstract: A messaging method is described in which avatars, representative of attributes of users and individuals, are used for capturing information and/or selecting users or individuals. In one embodiment, an avatar is rendered in response to attributes input by a user, and a matching and retrieval selects records from a database. Avatars are rendered in accordance with the attributes in the records. The user selects an avatar, and is able to communicate anonymously with the individual. Methods and systems for capturing data using avatars and selecting individuals using avatars are also described.
