Inventor: HIGGINS SHERYL W
IPC: A61F2/82
Filed: 1993-05-12
Abstract: A catheter combination is described using a percutaneous transluminal transmitter for transmitting energy to a localized area. The combination includes a catheter (20) having a hollow tubular member (22). A transmitter combination for partial insertion into the catheter (20) includes a continuous central conductor (82) terminating in a tip (86) for receiving and transmitting a signal to the tip (86). A dielectric material (88) surrounds at least a significant portion of the central conductor (82), and a continuous coaxial conductor (90) surrounds the dielectric material for receiving and transmitting a signal to a point adjacent the tip (86) to form an antenna for transmitting energy to tissue when the transmitter is placed into biologic tissue. A coating around the coaxial conductor (90) covers the coaxial conductor (90). A signal generator (48) is coupled to the central conductor (82) and the coaxial conductor (90) for applying a signal between the central (82) and coaxial conductors (90) to transmit energy from the tip (86) of the central conductor (82).

Title: Technique sans clonage d'expression d'un gene interessant
Inventor: SELBY MARK
IPC: C12N15/65
Filed: 1999-04-13
Abstract: L'invention concerne une méthode sans clonage d'expression d'un gène intéressant dans une cellule hôte mammalienne. L'invention fait appel à trois éléments individuels de base : (1) un élément promoteur ; (2) au moins un gène intéressant ; et (3) une cassette de marqueur pouvant être sélectionné et comprenant dans un ordre 5' à 3' un site intérieur d'entrée du ribosome (? IRES ?), au moins un gène codant un marqueur pouvant être sélectionné et une séquence de terminaison de transcription. Les trois éléments individuels sont cotransfectés dans une cellule hôte d'un mammalien où ils deviennent liés de manière fonctionnelle de sorte que l'expression des gènes de marqueur pouvant être sélectionné nécessite forcément une coexpression des gènes intéressants.

Abstract: The quality of reconstructed speech on which background
noise is superimposed is improved in a speech signal decoding
apparatus for generating a speech signal by driving a filter,
which is constituted by linear prediction coefficients, by an
excitation signal. A smoothing circuit smoothes sound source
gain in a noise segment using sound source gain that was obtained
in the past. A smoothing-quantity limiting circuit calculates
an amount of fluctuation represented by dividing, by the sound
source gain, the absolute value of the difference between the
sound source gain and the sound source gain that has been
smoothed, and limits the value of the smoothed gain in such a
manner that the amount of fluctuation will not exceed a certain
threshold value.

Abstract: A method for determining the state of charge of a storage battery, wherein at least two methods of different approach for determining state of charge are simultaneously applied. The individually obtained results of the different methods are weighted in accordance with their respective reliability in the respective current or former operating situation of the storage battery, and the weighted mean value of the individual methods thus obtained is used as final output variable of the method and displayed. The voltage of the storage battery, the current flowing through it and its temperatures are measured, and the different methods use these input variables and variables derived from these input variables as final input variables. At least one of the different methods uses the integration of the current flowing through the storage battery to determine the changes in the charge content of the storage battery. At least one other of the different methods uses a mathematical model which is implemented on an electronic computer and simulates the behavior of the storage battery.

Abstract: A receiver, comprising an adaptive filter, performs blind equalization using a
modified form of the constant modulus algorithm (CMA). This modified form of CMA is
referred to as symbol CMA (SCMA). SCMA utilizes both the constant  R  and the sliced
symbols,  A ∧ n   , in performing blind equalization. The constant  R  is statistically related to the
sliced symbols,  A ∧ n   . The adaptive filter is a two-filter structure. The SCMA blind
equalization technique reduces the rate of occurrence of a diagonal solution.
