Abstract: ABSTRACT OF THE DISCLOSURE     A buoyancy system for a tension leg platform tether 10 or other element extending a significant vertical distance through a body of water.  A series of bulkheads 25 divide the interior of the tether 10 into individual buoyancy cells 31.  A central access tube 32 extends along the central axis of the tether 10, passing through a sealed penetration in each bulkhead 25.  A series of cascade conduits 42 are provided the lower portion of each buoyancy cell 31 in fluid communication with the buoyancy cell 31 immediately above.  A tool 82 is provided for injecting air into a selected buoyancy cell 31.  As air is injected, water exists through the central access tube 32 until the buoyancy cell 32 is emptied of water, at which point air passes through the cascade conduit 42 into the adjacent upper buoyancy cell.  The tool 82 can also be used to selectively flood individual buoyancy cells 31.

Abstract: DIGITAL SPEECH CODER WITH DIFFERENT EXCITATION TYPES     Abstract An improved speech analysis and synthesis system where pitch information for excitation is transmitted during voiced segments of speech and modified residual information for excitation is transmitted during unvoiced speech segments along with linear predictive coded (LPC) parameters.  The speech analysis portion of the system uses a pitch detection circuit to determine when the speech is voiced or unvoiced and to calculate the pitch information during voiced segments.  A multi-pulse excitation forming circuit generates the modified residual signal which is obtained from the cross correlation of the residual signal and the LPC-recreated original signal.  The pitch detection circuit controls a multiplexer which selects either the output of the multi-pulse excitation forming circuit or the output of the pitch detection circuit for transmission as the excitation information with LPC parameters to the synthesizer portion of the system.

Abstract: Abstract of the Invention A radar receiver having a feed-forward control circuit for adjusting the automatic gain control (AGC) setting in 6 dB increments for each range cell in a next sweep based on the AGC setting of each corresponding range cell in the present sweep, the magnitude of the larger of the in-phase (I) or quadrature (Q) components of the video signals of the present sweep from an A/D converter, the status of present sweep and previous sweep A/D limit conditions, and a selected guardband thereby holding the level of the radar return signal within the dynamic range of the A/D converter.  The AGC setting is adjusted using a switchable attenuator which changes the level of the video signal into the A/D converter in 6 dB increments, each increment corresponding to a common I and Q data exponent directly used for floating point signal processing.  A pulse interference detection and signal replacement apparatus and method utilizes an 8-bit log magnitude representation of each range cell sample generated from a floating point exponent and reduced precision mantissa components to detect a range cell pulse of interference at a specific range M and causes replacement of the range cell sample with an interpolated value determined from the average of the radar return signals of adjacent sweeps at range M.

Abstract: ABSTRACT            A method for automatically extending the size of a segment in a page segmented virtual memory data processing system. The method increases the size of a segment in blocks of 64K virtual pages in response to the system detecting that the requested page has been protected. The conventional UNIX type System Calls create and open files in virtual memory. All pages are protected "read only" until a SHMAT type System Call is made to operate on a page at a specific address. At that point in the process, a protection exception is recognized by the system and the UNIX kernel takes control to remove the protection and update the appropriate data structures to reflect the new status of the page and the addresses in real memory where the page may be found.          Segments containing mapped files are also extended by the method.

Abstract: ABSTRACT           A decision timing control circuit particularly for use in demodulating multi-level QAM signals is disclosed.  The circuit includes a demodulator  which demodulates a multi-level modulated received signal and outputs a multi-level signal, and an A/D convertor operatively connected with the demodulator for converting the multi-level signal input into a corresponding digital signal.  A clock recovery circuit operatively connected with the demodulator, recovers the clock from the multi-level signal.  A variable phase shifter is operatively connected with the clock recovery circuit and the A/D convertor for outputting the phase of the recovered clock to the A/D convertor by shifting it with an applied control signal.  An error rate detector operatively connected with the A/D convertor outputs a value corresponding to the actual error rate as the error rate information by obtaining such value based on the digital signal.          Finally, the decision-timing control circuit includes a phase controller which is operatively connected with the error rate detector and the variable phase shifter for varying the amount of phase shift at the variable phase shifter with the control signal so that the error rate becomes small on the basis of the error rate information.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of high-speed magnetic resonance imaging in  which the object to be imaged is placed in a high static magnetic field.   Nuclear spins are excited in an image area in a selected plane of the object by superimposing a slice-selection gradient along an axis and applying a pulse of radio frequency magnetic field.  Following an encoding pulse sequence  and  rephasing  of  the  nuclear  spins  by  the application  of  a  180°  radio  frequency  pulse,  mutually orthogonal   phase-encoding   and   readout   gradients   are alternately applied in the image plane to effect a traversal through spatial frequency domain (k-space).   In a preferred embodiment of the invention, the readout gradient is applied as a continuous sinusoidal wave.  If phase errors vary slowly in time, only a partial k-space trajectory is required.  In one  variant  of  partial  k-space  imaging,  the  trajectory extends over the k-space origin, and the information acquired from  the  extension  is  used  to  compensate  for  any phase errors.  If the same number of points are collected as in a full k-space acquisition, signal bandwidth is maintained, and spatial  frequency  response  is  increased.    In  a  another variant,  two  or  more  partial  k-space  acquisitions  are performed and then pieced together in a "mosaic" prior to Fourier transformation.   In a further variant, partial k-space acquisitions in the direction of the readout gradient are combined with interleaved acquisitions in the direction of  the  phase-encoding  gradient  to  avoid  discontinuities. Chemical shift is eliminated either by the application of a suppression pulse of RF field or by tailoring the frequency spectrum of the rephasing pulse so as to preclude rephasing of one or other of the chemical moieties.

Abstract: An undersea cable plough for laying of a cable or conductor previously laid out on the bottom in a trench comprises a frame which can move forward along the bottom, a digging element and carrying elements for the cable or conductor. As the plough moves forward along the cable or conductor, the latter is led in a bend above the frame and down into the bottom of the trench. It is difficult to exactly follow the laid-out cable or conductor, and deviations from the correct direction of travel and jerking during movement results in skewed tensile stresses, which can damage or even break the cable or conductor. These inconveniences are avoided when the frame is comprised of a chassis for a controllable vehicle, which is provided with an element 16 for sensing the direction of the cable or conductor entering with the vehicle in the horizontal plane and with a mechanism controlled by the sensing element 16 for automatic influencing of the control equipment of the vehicle in such a way that the direction of movement of the vehicle is adjusted in the direction of the cable or conductor. <IMAGE>
