Abstract: Four stage production of enantiomer-pure bis-diphenylphosphine oxides starting from an aromatic bromo-compound and a diphenylphosphine acid chloride is effected under specified conditions. Production of enantiomer-pure bis-diphenylphosphine oxides of formula (I) comprises: (i) reacting a bromo-compound of formula (IIa), after selective mono-metallization, with a diphenylphosphine acid chloride of formula (II) to give a diphenylphosphine oxide of formula (III); (ii) metallizing (III) in the 6-position and reacting with I2 to give a 2-iodo- diphenylphosphine oxide of formula (IV); (iii) converting (IV) with Cu to a racemic bis-diphenylphosphine oxide of formula (I); and (iv) crystallizing the racemic (I) with enantiomer-pure mono- or di-carboxylic acids to separate it into its enantiomers, the process being such that: (a) the solvent in step (i) is a mixture of THF and an aromatic hydrocarbon, the acid chloride (II) being added without solvent and the oxide product (III) being isolated from its solution in the aromatic hydrocarbon by addition of a saturated aliphatic hydrocarbon; (b) step (ii) is at not less than -25 degrees C and the metallized (II I) and I2 are introduced simultaneously such that there is always a small amount of I2 in excess, the iodinated intermediate (IV) being separated off dissolved in an aromatic hydrocarbon; (c) dendritic Cu and an aromatic hydrocarbon solvent are added in step (iii) and the racemic (I) is crystallized from solution in an aromatic hydrocarbon; and (d) an enantiomer-pure mono- or di-carboxylic acid is added and the first enantiomer is recovered by crystallization from solution in an aromatic hydrocarbon, while the second is recovered by hydrolysis followed by crystallization from solution in an aromatic hydrocarbon.   R<1> = phenyl, naphthyl, heteroaryl (with 4 or 5C and 1 or 2 N, O or S heteroatoms) or cyclohexyl, these optionally being substituted by R, OR, NO2, NH2, NHR or NR2; R = 1-6C alkyl; R<2> = 1-4C alkoxy; R<3> = H, F, Cl or Br; and R<4> and R<5> = H, F, Cl, Br or 1-6C alkyl or alkoxy.

Abstract: The invention concerns the use of phosphatidylserine (PS), lyso-phosphatidylserine or/and a physiologically acceptable salt thereof for the treatment of the attention deficit syndrome (ADHS) in small daily doses over a longer time period and in larger daily doses over a short period as well as in combination with suitable additives selected from the group comprising antioxidants, essential fatty acids, mineral substances, amino acids, mood-lifters or/and phospholipids. In this connection it is preferred to carry out the administration to probands aged 2 to 20 years preferably 3 to 10 years whereby the phosphatidylserine as well as the additives are used in solid and also in liquid formulations. Due to its positive properties phosphatidyl-serine is in particular suitable as a therapeutic agent or food supplement in connection with ADHS. The good tolerance of phosphatidylserine even in high doses and over a longer supplementation period and the excellent compliance should also be stressed.

Abstract: A data rate detecting device detects a data rate for a received signal based on a variation of the energy for the respective received signals between the two adjacent intervals upon failure to receive information about the data rate, and performs channel decoding of the detected data rate information. First, the data rate detecting device divides an interval defined as between a lowest and highest one of a plurality of given data rates into m discriminating intervals. Then, the device calculates a difference between an average energy of received signals up to an i'th discriminating interval and an average energy of received signals for an (i+1)'th discriminating interval, wherein i is an integer is less than m. If the difference between the average energies is greater than or equal to a threshold value, the device determines that the received signal in the (i+1)'th discriminating interval is transmitted at a data rate corresponding to the i'th discriminating interval.

Abstract: A sharps cup for receiving and storing a plurality of needles against accidental dislodgement, includes a plastic cup defining a bottom, a top, a sidewall connecting the bottom and the top, and a vertically extending central post disposed within and horizontally spaced from the sidewall. A resilient disc is disposed within the cup and defines a plurality of slots and segments, the segments being intermediate the slots, and each segment having a free end spaced from the post. A plastic cover for the cup defines a plurality of needle-receiving passageways therethrough adjacent the post and communicating with spaces between the post and the segment free ends. Each segment free end is individually deflectable toward the bottom adjacent the post by insertion of a needle downwardly through one of the passageways and then into the space intermediate the post and the segment free end. The disc is of a harder material than the needle so that the segment resists withdrawal of the needle by biting into the needle as the segment free end attempts to return from its deflected orientation during withdrawal of the needle.

Abstract: A method for determine blurring in a test video sequence due to video processing includes detecting blocks within each frame of the test video sequence that have valid image edges. An edge point within each valid image edge block is selected and a series of points defining an edge profile in the block along a line normal to the valid image edge at each edge point is defined from an enhanced edge map in which video processing blockiness artifacts have been removed. From the edge profile a blurring value is estimated for each frame or group of frames within the test video sequence. Additionally a reference blurring value may be derived from a reference video sequence corresponding to the test video sequence, which reference blurring value may be generated at a source of the reference video sequence and transmitted with the test video sequence to a receiver or may be generated at the receiver. The reference blurring value is then compared with the blurring value from the test video sequence to produce a relative blurring value for the test video sequence.
