Abstract: A method of increasing the HDL concentration and the HDL/LDL concentration ratio in human serum by providing a balance between a sufficient and required proportion of cholesterol-free saturated fatty acids in the daily dietary fat of the human and a sufficient and required, but not excessive, proportion of polyunsaturated fatty acids comprising linoleic acid in dietary fat, while the remaining proportion of fatty acids and energy from the dietary fat is provided by monounsaturated fatty acids comprising oleic acid. The saturated fatty acids must constitute between 20% and 40% by weight of the daily dietary fat based upon dietary fat accounting for 30% of the total dietary energy consumption, and linoleic acid must constitute between 15% and 40% by weight of dietary fat. In this way, the required proportional intake of polyunsaturated fatty acids enhances the formation of HDL from VLDL and/or decreases the clearance of HDL, while an excessive proportional intake of polyunsaturated fatty acids and monounsaturated fatty acids is avoided to assure a sufficient dietary availability of saturated fatty acids which are required for sufficient VLDL synthesis and HDL production.

Title: Videophone system
Inventor: SPRUCK MANFRED
IPC: H04N5/238
Filed: 1996-10-25
Granted: 2004-05-11
Abstract: In the case of a videophone system, it is known to vary the amount of light falling onto the target by a shutter, which is electronically controlled for a greater or lesser length during a short exposure time, rather than by means of a controlled mechanical aper- ture. It has been found that interference occurred when data reduction was used for the signal to be transmitted. In particular, macroblocks were also formed when no difference signal was present. The object is to develop such a videophone sys- tem such that interference of this type is avoided in the case of data reduction. The control circuit for the exposure time and the mains power supply which produces the ambient light are coupled by means of a PLL circuit in such a manner that the exposure time always occurs at the same phase of the mains voltage. In particular for a videophone system having an electronically controlled shutter and data reduction for the transmission.

Abstract: A well collar counting methodology is provided comprising first obtaining acoustic pulse data from a well and then digitizing and storing the amplitude-versus-time signal for subsequent processing. The raw signal is processed by applying a Wavelet Transform thereto for producing multiple resolutions of the signal, preferably four, at least one of which has a transformed signal resolution sufficient to distinguish reflections emanating from collars, and one of the coarser resolutions having a transformed signal resolution sufficient to distinguish reflections emanating from the fluid surface as kicks. The fluid surface kick and repeat kicks are determined by performing multi-resolutional analysis of each maximum, at the coarser resolution, as synchronized against the successively finer resolutions and compared as being significant with respect to adjacent maximums. Tubing collars are then counted at a finer resolution, as being reflection maximums counted in the interval between the wellhead and the kick, irrespective of tubing joint length or collar frequency. Direct collar counting, interpolation and extrapolation of collars is performed.

Title: Telephone line interface circuit with voltage control
Inventor: ROSCH REINHARD W
IPC: H04M3/22
Filed: 1993-03-17
Granted: 2000-02-15
Abstract: A telephone line interface circuit comprises two unity gain d.c. amplifiers (132, 134) having outputs d.c. coupled via feed resistors to the line wires. Currents in the feed resistors are monitored via a digital control circuit (152), which can be programmed to provide desired operating conditions. The control circuit controls, via D-A converters (158, 160), currents passed by current sources (142, 148) through resistors (140, 146) at inputs of the d.c. amplifiers, thereby determining voltages at the amplifier inputs and hence on the line wires. These d.c. voltages are smoothed by capacitors (136, 138) used for coupling an a.c. signal to the d.c. amplifiers. The voltage control facilitates adaptive adjustment of the line interface circuit to the line in dependence upon the monitored currents.

Abstract: An optical cross-connect node architecture interfaces plural optical fiber input and output links, each link containing plural wavelength channels. In one embodiment, the input links are connected to an optical coupler. Pairs of tunable optical filters and optical wavelength converters are each connected to an output port of the optical coupler and perform wavelength channel routing and switching in the wavelength domain, i.e., without the need for any optical space switch. In another embodiment, an additional input wavelength converter is connected to each input fiber link to convert the plural wavelength channels on each link to different, non-interfering wavelengths. This prevents wavelength contention in the optical coupler to which the input wavelength converters are connected. New fiber links may be added in modular fashion without significant impact on the pre-existing optical cross-connect structure. Similarly, new wavelength channels may also be multiplexed onto existing fibers to provide wavelength modularity without having to reconfigure the node.

Abstract: A road vehicle sensor provides an output signal having a magnitude which varies with time through a plurality of values as a vehicle passes the sensor. Signal processing apparatus monitors the timing of sensor signals generated from sensors in adjacent lanes of a highway and provides an indication when such sensor signals could correspond to a double count with a single vehicle being detected by both sensors. Then, the geometric mean of the amplitudes of the sensor signals fr om the sensors in adjacent lanes is calculated and is used to indicate a double count if the geometric mean is below a threshold value. Signal processing arrangements are also described to detect tailgating vehicles which may be simultaneously detected by a sensor, and fo r determining the length of slow moving or stationary traffic.
