Abstract: The invention is directed to a method for increasing the overturning moment resistance of a jack-up drilling rig that includes the step of attaching at least one lateral leg support to at least one jack-up leg, wherein the jack-up leg is secured and has a lattice framework. The invention is also directed to a system and apparatus for increasing the overturning moment resistance of a support member with a lattice framework.

Abstract: The spatial sound conference system enables participants in a teleconference to distinguish between speakers even during periods of interruption and overtalk, identify speakers based on spatial location cues, understand low volume speech, and block out background noise using spatial sound information. Spatial sound information may be captured using microphones positioned at the ear locations of a dummy head at a conference table, or spatial sound information may be added to a participant's monaural audio signal using head-related transfer functions. Head-related transfer functions simulate the frequency response of audio signals across the head from one ear to the other ear to create a spatial location for a sound. Spatial sound is transmitted across a communication channel, such as ISDN, and reproduced using spatially disposed loudspeakers positioned at the ears of a participant.

Abstract: A digital subscriber link data network incorporates a throughput test server (TTS) to provide fault identification, isolation, and verification of DSL service availability and data rates. An asymmetric digital subscriber line (ADSL) terminal unit—remote (ATU-R) is connected to an ADSL terminal unit—central office (ATU-C) over a conventional copper loop or equivalent. Data connectivity via a packet switch provides access to high speed data networks, TTS connectivity and interfaces to service providers (SPS). Upon receiving a test request, a technician routes a customer to the TTS. The customer uses a web browser to access the TTS and download executable testing software, e.g., a JAVA applet. The applet causes test messages to be sent to and received from the TTS and computes upstream and downstream data rates that is displayed to the customer together with whether the measured data rates are consistent with a specified class of service.
