Title: Cascade low-pass filter to improve xdsl band attenuation for pots splitter
Inventor: WANG JIE DONG
IPC: H03H7/01
Filed: 2003-04-09
Granted: 2012-01-17
Abstract: Cascade low-pass filters are useful in attenuating the xDSL band in a POTS splitter. The design of the low-pass filter is a sixth-order filter having two stages. A first stage includes a fourth-order filter, preferably with a stop-band frequency of approximately 48 kHz. A second stage includes a second-order filter in cascade with the fourth-order filter. For this filter, the stop-band frequency is preferably approximately 29 kHz. The inductance value of the second stage is relatively small in comparison to the inductance values of the first stage. In this manner, improvements in xDSL band attenuation are facilitated with little or no eroding of the voice band performance such as insertion loss, pass-band attenuation and return loss.

Abstract: An agitation system for a mud tank to prevent core material initially suspended in the drilling mud, from settling. The method agitates sludge and eliminates the need to hand shovel sludge from the tank after dumping. The method comprises the step of pumping mud taken from within the tank through a permanently mounted rubber nozzle directed at mud on a bottom portion of the tank. In a preferred aspect of this invention the tank is a cylindrical and longitudinally mounted on a truck for waste mud hauling, and has a rear end cap hinged to a top portion of the tank, so that when a front portion of the tank is marginally elevated and the end cap is hinged opened, mud dumps from a rear end portion of the tank.

Abstract: The present invention relates to the discovery that the T1R receptors assemble to form functional taste receptors. Particularly, it has been discovered that co-expression of T1R1 and T1R3 results in a taste receptor that responds to umami taste stimuli, including monosodium glutamate. Also, it has been discovered that co-expression of the T1R2 and T1R3 receptors results in a taste receptor that responds to sweet taste stimuli including naturally occurring and artificial sweeteners. Also the present invention relates to the use of hetero-oligomeric taste receptors comprising T1R1/T1R3 and T1R2/T1R3 in assays to identify compounds that respectively respond to umami taste stimuli and sweet taste stimuli. Further, the invention relates to the constitutive of cell lines that stably or transiently co-express a combination of T1R1 and T1R3; or T1R2 and T1R3; under constitutive or inducible conditions. The use of these cells lines in cell-based assays to identify umami and sweet taste modulatory compounds is also provided, particularly high throughput screening assays that detect receptor activity by use of fluorometric imaging. Finally, the invention relates to the discovery that some compounds, e.g., lactisole, inhibit both the activities of human T1R2/T1R3 and T1R1/T1R3 receptors, and accordingly the sweet and umami taste, suggesting that these receptors may be the only sweet and umami receptors.

Abstract: A method and apparatus for screening, sensing, or diagnosing disease states by obtaining a plurality of electrical impedance data measurements in organized patterns from two anatomically homologous body regions, one of which may be affected by disease. One subset of the data so obtained is processed, compared and analyzed by structuring the data values as elements of n × n impedance matrix, and characterizing these matrices by their eigenvalues and eigenvectors. Another, not entirely exclusive subset of the data is alternatively processed, compared and analyzed by plotting the impedance data as chords of two circles representing the two homologous body regions. Impedance chord plots provide a visual indication of certain disease states and their location.

Abstract: On applique un cathéter à ballonnet pour le traitement du système lacrymal d'un patient de manière transnasale sans qu'il soit nécessaire de faire appel à un fil guide ou à un élément de retenue courbe. Le cathéter est constitué d'un hypotube en acier inoxydable et présente une rigidité et une résistance en colonne suffisantes pour pousser le cathéter dégonflé depuis la cavité nasale du patient à travers une petite ouverture préparée étanche pratiquée à travers la paroi nasale latérale et la fossette lacrymale en direction du sac lacrymal. Le cathéter présente une tige proximale et un segment distal fléchi selon un angle de 70· à 115·, de préférence 90·, vers la tige proximale. Un élément gonflable est monté autour du segment distal et est lié de manière adhésive à l'extrémité distale de la tige proximale, le cintre et l'extrémité proximale du segment distal et à la partie distale du segment distal. On obtient la petite ouverture préparée étanche en poussant de petits orifices à travers le cul-de-sac médial, la fossette lacrymale et la paroi nasale latérale à l'aide d'un instrument et en coalesceant des orifices afin de former ladite ouverture. Le cathéter est introduit dans la cavité nasale et tourne, ou se déplace, de manière à aligner le segment distal sur l'ouverture préparée. Le segment distal est ensuite poussé à travers l'ouverture préparée et on applique un fluide sous pression sur le cathéter afin de gonfler l'élément gonflable et de dilater l'ouverture préparée.
