Abstract: Apparatus for locally disturbing an underwater bed to enable the burial of an elongate member (39) comprises a mounting (30,31), resilient means (88-93) such as brush filaments coupled to the mounting, and means (9) for moving the resilient means with respect to the mounting. The resilient means is constructed such that on moving the mounting along the line of the elongate member while moving the resilient means with respect to the mounting, the underwater bed is disturbed by the resilient means to enable the elongate member to be buried.

Abstract: A communication system, comprising at least one mobile handheld telephone handset adapted to communicate with a telephone network handling system. The handset comprises means to produce first signals dependent thereupon, means to produce a voice transmission signal and means to transmit the voice transmission signal. The handset also comprises first processing means to carry out a speech recognition process to produce initial feature analysis parameter coefficients data dependent thereupon. The first processing step preserves predetermined information. The handset further comprises means to produce a data transmission. The telephone network handling system comprises means to receive the voice signal, means to forward the voice signal, and means to receive and process the data transmission signal. The telephone handling system also comprises means to carry out the remote second processing step in a speech recognition process on the regenerated data.

Abstract: A communication system comprising at least one mobile handheld telephone handset adapted to communicate via a wireless telephony medium with a telephone network handling system.The handset comprises input devices to receive input from a user and produce signals dependent thereupon, an onboard processor to adapt speech input to produce a voice transmission signal as part of a telephone conversation with a third party; and an antenna to transmit the voice transmission signal via the wireless telephony medium.The telephone network handling system comprises a receiver to receive the voice transmission signal, and means to forward the voice signal to a third party.

Abstract: An underwater plough for ploughing an underwater bed, the plough comprising a first share (10) and a second share (21) which is movable with respect to the first share whereby the depth of the ploughing profile presented by the plough can be varied.
